Return of Blitzkrieg Gensokyo

by WildMath55

20 years after Final Armageddon Warfare, Gensokyo Union Fighters become one of the major powers in Multiverse. They already have contact with United Gensokyo Forces. But recently, their relationship disturbed since GUF ally themselves with Humanity Military Force. Meanwhile, another Gensokyo, forgotten by history, finally appears... Collab with Lt Colonel Summers and Xovercreator

3. The Call to Arms

AN : I just finished reading Wild and Horned Hermit, and surprised to see the info about a particular Sage that we suspect being an Oni. Want to know the answer? It's true, and heck, I'm really shocked to see her true form. If you remember Vaati Star'sseries, Fugere Illusion, we see that other characters also suspect her as Oni. Good thing I also pick Fugere Illusion's timeline as one of basis for Historia Gensokyo.

Luckily for GUF, the Blitzkriegers didn't catch the wind of this, being restricted to Touhou games timeline base only, as opposed to Historia Gensokyo, which implements events according to Gensokyo's timeline listed in Touhou Wiki, with some changes. I'll put it in motion here. Oh, who do I mean? Right, she's Kasen Ibaraki, one of Gensokyo Sages. It's not Hilarious in Hindsight at all, mind you! Rather, take caution if you try to harm any of GUF allies' sovereignty.

On Chapter 1 from HMF perspective, ten Nation Leaders already decided to join their man. No need to worry about them. LT already said previously that he and all Nation Leaders already injected by Super Serums that based from RAIDERS' DNA. Like he said again, Authority Equals Asskicking! Go for it, HMF! Defend your world at all cost! (This Chapter is set before GUF arrives in Neo-Gen Outside World)

(This AN was made months ago.)

Disclaimers are in the Prologue. And then… "To arms! Under one banner!"

Return of Blitzkrieg Gensokyo Chapter 1 (GUF)

The Call to Arms

Date : May 11th, 2055 (Historia Universe Time)
Location : GUF Headquarter/Hakurei Shrine, Floor B4

Soon after the meeting ends, Yasei gives directives to all Guardians. "We need to do the head count once again to affirm the responsibility we have to take. Call every single registered GUF Members in the Factions and gather at the open fields where UNAF soldiers are resting. After we done it, we will go to Neo-Gen Outside World at haste." With nod from all Guardians, Yasei dismiss them, and went to the Central Command Room.

Yasei's POV

Okay, so the first thing I have to do is to inform Yayoi-san regarding this. It might be awkward, since she only comes later after Final Armageddon Warfare, but I don't want to regret it again. So I asked Yukari to bring me to year 2009, where she recently graduates and luckily for me, she reacts like usual, and asks me about how's the mission is going. Probably thanks to the time drift, I was able to reply her and don't have to worry about my current status. That's when she told me that she hasn't read the letter sent to her from her grandfather, Masayuki Kochiya. Apparently, he already passed away when Yayoi-san graduates. I offer her to go to her current residence, and being quick-witted, she cuts her hair to the usual style I know, in order to avoid confusion. Ah, sorry about that. I tend to flashbacks a lot. But now isn't the time!

Thankfully, she's still there, and apparently, perhaps a coincidence or not, all GUF Support members are in the room as well.

"Yayoi-san, there's something I need to tell you!" I called her, and she complies. Out of any GUF members, only two people that I ever call with -san suffix, one is Iesua-san, and the other is Yayoi-san, my senpai back in Historia Outside World. "Is this regarding the current event? I heard that Blitzkrieg Lotus Army already invades Neo-Gen Outside World during the meeting." Like I said earlier, she's quick-witted, and also sharp. It must be cool to graduate from a university… Sanae and I drop out on our Third Year in High School…

"Indeed. Before that… How's it going, the Chroniclers?" By Chroniclers, I refer to Hieda no Akyuu, the ninth Generation of Miare descendants, Saya Kurahinata, the descendant of Misaki, and Kosuzu Motoori, GUF main book decipherer. Something is puzzling me. I wonder why, but did Akyuu survive living past 30 years because Kurahinata comes here…? That's not something I should search for now.

"From the info we gathered from the meeting, we conclude that the Blitzkrieg Lotus Army also based from the canon Gensokyo, just like our Gensokyo Union Fighters and United Gensokyo Forces, albeit with some differences. Their timelines are highly connected to the Incidents, with little details from other Gensokyo historical work, such as Gensokyo Chronicle." Akyuu sure is fast when it comes to this. Make sense. Miare descendants are known as Chroniclers of Gensokyo. And seeing that our universe is refered as Historia, you know where it went.

"I know I can't do much, but I will support GUF with all my best. And because of that, I asked Kochiya-san to integrate my skills as one of GUF Universal Support Skills." Wait, I didn't expect that coming from you, Kurahinata. But thanks. "I see… Does that mean your skill integrated as well, Kosuzu?" Kosuzu cheerfully smiles and she nods her head. "Right, and thankfully, it's passive skill. That means every GUF member shares my ability now, and the information received will be sent to the Central Command."

That sure is a big boost. Information is the most important when it comes to intelligence. That's why, when Yayoi-san says she want to join GUF as a full-fledged member, I decided to make a Support team to accommodate her, since she can't fight in battlefronts. Sure enough, many locals are joining as well. "Not to be rude, but am I placed here because my lack of interest and skills in danmaku duels?" That's Kourin. His full name is Rinnosuke Morichika. He's a hybrid of human and youkai. "While that might be the case, you are here because your ability is as important as Kosuzu, Kourin."

Kourin fell silent before realizing that there are many outsiders in GUF. "Right. There's already many elite Outsiders here. Thanks for reminding me." I wave my hand and tell him not to worry about that. "It's okay. At least you know now." Then I noticed that Merry (Maribel Hearn) and Renko (Renko Usami) is in the room as well. "I'm surprised to see you two here. It's rare actually, for you two to come here." They giggle at the same time. Huh… Future girls… I can't blame them, though. I know exactly how it feels, like I explained before.

"Indeed it is, and only Renko that comes here frequently." I think I know where this is going… "I see… Living GPS… Add it with Living Radar, and they make a perfect couple." Sure enough, Renko blushes. Spot on, it seems. "Don't worry about that. I only want to ask if you two are ready for this. It will be the first time GUF intervenes directly in AU matters." Just like most of GUF Support team, they can't fight. But they have the needed skills to support GUF. Both of them nod at the same time. "We're ready."

And with that, I checked the list of GUF Universal Support Skills.

- Advanced Information Processing/Passive (Yayoi Kochiya)
- Healing Art of Misaki Lineage/Active (Saya Kurahinata)
- Advanced Boundary Detection/Passive (Maribel Hearn)
- Advanced GPS Interface/Auto-Activation (Renko Usami)
- Full Memory Saving/Auto-Activation (Hieda no Akyuu)
- Literature Deciphering/Passive (Kosuzu Motoori)
- Advanced Item Description/Passive (Rinnosuke Morichika)

"Good. In the meantime, I'll go ahead to build a moving Headquarter. That way, the Support team can help GUF at battlefront." It is the first time, indeed. But we have to use everything we have in our disposal. That means we need supports as well. And knowing Mark, he's most likely aware about the reason why I said that. To my surprise, they nod. I actually expect some reluctance, but it seems they know I won't say it without deep planning. So I go ahead and inform them to come after I done with it.

Reimu's POV

One thing I didn't expect, is that Yasei endures the shock and proceeds to do the meeting like usual, even though he knows that Kasen is confirmed to be an Oni, and not any ordinary Onis, but one of the Four Mountain Devas, at that… As expected from him. That's why he's the Zen Captain. Putting that aside, I have to call every single group leader here. I'm sure he will give notice to every GUF Elites member. With that, I took my smartphone, and began calling. Good thing it's upgraded so multi-call is possible.

"Is any Gensokyo Group Leaders here?" I wait for few seconds, until someone replies. "Oh, Reimu-san! I didn't expect you to call me as well." That's Letty. I think she already married with Arcluz, and probably thanks to her SGGK training, she can fight out-season now. "Right. Assemble all Neo Sub-Characters to the open field, and wait for further information." It didn't take long for her to comply, since she cuts the call afterward. "Oh, if it isn't the red-white shrine maiden. At least I recognize your voice, you know." Yuugi… Hate to admit, but she's also one of the group leaders I mention earlier. "Right… At least you're more reasonable than Suika… You know what this call means." Again, she complies with cutting the call.

"Ayaya… Did I miss something?" That paparazzi tengu… "No, and your group are called as well. Tell your colleagues and superiors about this." I didn't even bother to hear her response, and cuts the call with her. "I assume this have something to do regarding Danmakufu Faction." Now it's Kanako… Well, she's Sanae's patron, and quite cunning. "Right. There are many Danmakufu members that joins our groups, and Iesua already calls the group that led by Danmakufu members." She complies, but unlike them, she replies. "Very well. Let's maintain the good relationship we have with them." Then she cuts the call.

That leaves four more groups. It's too long if you ask the detail, but in short, everyone complies. At last, I can call it finished from our part. Our part? Yep, me and Iesua. Our factions are the natives, after all.

Oh, and as of why I say that first line, you need to know a certain flashback I have, more precisely when I actually fought him. I'll skip it to the end part for this.

March 10th, 2019, in Hakurei Shrine area, Gensokyo (Reimu's Flashback, Normal POV)

*pant* *pant* Both Reimu and Yasei pants heavily because the fatigue they get on their fight. 'Dang… Reimu did have an impressive amount of stamina… Must've because her experience in Incident Resolving.' Yasei thinks about how their fight dragged for so long. He also can read what's in Reimu's mind, and actually didn't expect that she already knows about his Living Radar. Why? 'Do you really think so? I actually quite shocked when Yukari told me that you beat her back then. Also, your actions during this whole fight… It's as if you already knew about my moves.'

(Wow, did Reimu also gain Telepathy? Guess there'll be silence in literal sense…)

Needless to say, Yasei is surprised by that. But it didn't last long. 'I must admit, Yukari is right about you. But it's time to end this farce once and for all.' He makes a serious face to show his point. Reimu got what it means, but only partially. 'Right.' Then both of them prepares for a final strike. Yasei holds his Iron Metric Sword tightly, while Reimu holds her gohei. Seconds later, they charge at each other quickly, and end on the exact opposite side.

Yasei's Iron Metric Sword shatters in pieces and he is facing Reimu's back. Then, something falls on her sides. It was a pair of horns. (Wait… horns?!) "Ungh…!" Realizing it, Reimu holds her head to cover the wounds. "Why did you… cut the horns…?" Reimu speaks slowly, because the wound she received is on the border of fracturing the skull. "There's something that bothers me all this time, and I intend to steer it back to the right direction before it becomes too late." Yasei replies as he looks at the pair of chained cuffs, which was in Reimu's hands before. (Hold on, chained cuffs?!)

"What do you mean…?" Somehow, Reimu speaks in normal pace. It probably hints something. "I'd rather not say this after finding out about your past, but I have to. I'm concerned about your inactivity for almost 15 years, and you only show up in relevant events (Incident Resolving, that is) to keep up with everyone else. All I want to say is…" To her surprise, Yasei bows to sign his sincerity. "Please, Reimu. I, no, we need you back. We need you back, as Hakurei Shrine Maiden."

Instead of replying, Reimu charges at Yasei. There's anger written on her face. The latter defends with a cross block, and he is surprised to see that she actually able to push him few feet backwards with a kick. "What makes you think you know everything about me?! Is it because of your Living Radar?! You don't know what I feel when Yukari told me that my family got massacred by the very same species we try to protect, and that means humans! I don't need your fake sympathy. Begone from my sight, Yasei."

But, to Reimu's surprise, Yasei didn't get angered by that. Instead, he walks slowly until he's right in front of her. And then…

*SLAP!*

"!" Reimu held her left cheek. She expects Yasei to return the favor, but instead, she got slapped. "Surprised, aren't you… Expecting me to return the favor, only to get this… Also, I'm already bitten by a vampire, and still trying to resist the vampirication process. Let me say it again. For our sake Reimu, please. I don't care about your views toward others. But I care about Gensokyo. This has gone for almost 15 years, and I can't imagine what will happen when this continues. Just please, at the very least, be more active." (Rescind that. Yasei is in Tranquil Fury.)

Yasei then writes something. He probably noticed that Reimu hesitates to say anything. "This is the very least you can do, for our sake. The role will be reversed from now on…" Confused by that statement, Reimu wants to ask, but decides not to. Instead, she reads the note Yasei write just before.

'If you really can't bear it, here's something that might ease you a little. Your role here is the balancer between human and youkai. That means, you should prevent any humans from the village to be eaten by youkai or become one themselves. Truth to be told, I'm already bitten by Flandre just after beating Remilia on Koumakan Challenge. I'd rather not say what makes her do that, for her sake. Right now, I'm in the middle of transforming into a kind of vampire myself. And I'll try to resist it as long as possible until it's inevitable for me to face you again in different circumstances. By then, your humanization is long since completed. Don't ask me or Yukari how's that even possible. Anyway, either you decided to kill me or spare me, know that I won't mind whatever your choice is, since I'm already considered as Outsider Immigrant here, and on the verge of becoming a youkai.'

Present Day (Reimu's POV)

… That note he gives to me that time… It's as if he foresaw this would happen. Like he said, I returned to be a human again, and he… He's no longer human ever since Liberal Clones Rebellion ended. In the end, I couldn't bring myself to kill him, unlike a certain jinyou that was a human once. What differs is the fact that the said jinyou already planned it, while Yasei didn't expect he would get bit. On that jinyou case, he is willing, and even planned to become a youkai, while Yasei resists the vampirication process as long as he can until he eventually become a vampire himself, more precisely Draconian, a sub-species that doesn't require blood to survive. He and Lucy are the first confirmed Draconians in Gensokyo, since Lucy also resists the same process after bitten by Remilia.

"Now then, I wonder what the others do… It's been five years ever since GUF actual intervention in Multiverse…"

Lithnanai's POV

For Yasei to welcome me here, I'm grateful for it. And for me to be part of GUF Guardians… I honestly wish there will be no war, but sometimes, it's just impossible to avoid. So, I call Omega, Azure, Nirvana, and Hana. Oh, for your info, somehow, all OCs on my saga managed to reach this Gensokyo as well. There's two known major conflict that roots to our faction. First one is from Azure, and the next is from Omega's inner self, Marisfelis. Thankfully, Yasei managed to resolve both.

"Are your group ready for this, Omega? This isn't as lethal as the war we have back then or the Great Wars here, but be careful. I don't want to lose anyone again, especially you."
"Fully ready, Lithnanai. All of the Doppel's former subordinates are waiting for the command."
"How about you, Azure? Make sure you don't cause trouble like that time. Good thing Yasei managed to resist it."
"… Okay, I'm sorry about that. And yes, all unaffiliated members are here."
"Nirvana, you don't have to join if you don't feel like it. We'll manage somehow."
"Our Gensokyo are already destroyed, and this is the only world we can consider home. No need to worry about me. Do what you must, as one of GUF Guardians."
"Thanks. Sorry for abandoning you that time, Hana. This time, I won't abandon you. I'm asking this not as a Guardian, but as your mother. Will you lend me your strength?"
"I will, mother. It's grim news for me that my step sister didn't manage to survive, but I will live on for her sake, now that I'm here."
"Again, thanks. And then, let us make haste."

Meimu's POV

I know Lithnanai-sama ever since before the Grand Tournament was held in Fantasia Gensokyo. And I participated on that tournament as well. If you speak about the wars that result in destruction of both Fantasia Gensokyo and Alterna Gensokyo, which is my home, I was there. At first, I was confused when I found myself in Historia Gensokyo, but after I learned that Lithnanai-sama was already arrived here, somehow it gives me relief. And what relief? I'm relieved to found Mitori, Sasha, and Satsuki has arrived here too. So, I decide to call Mitori. It didn't take long for her to answer it.

"Hey, it's been a long time ever since we arrived here, don't you think Meimu?"
"Yeah, very long time, indeed. Anyway, inform Mihana and Angra regarding this. GUF is at war again. And like in Final Armageddon Warfare, we will fight on their side."
"Okay. It seems you've been more… zealous lately. Is there something wrong?"
"Right… It's something about the past that I just can't forget."
"I see… Don't think too hard about it. I'll go contact them, as you told me."
"Please do so."

I ended the call and thinking about how much I progressed here. Now I even able to synchronize my moves with Reimu and her CRA counterpart, and because that we're called the 'Paradise Trinity'… I wonder what will the latter do after his decision to fight BLA…

Shirei's POV

Armageddon… That reminds me when we're facing each other on the Rebellion I invoked… You only have a handful of friends with you, while I have a literal army… You taught me that number and strength isn't everything, and I'm forever grateful that you give me a second chance as GUF member. And that feeling is what makes me swear my allegiance to you. Good for GUF, we in CRA have experience on invoking a war before, so we know how to exactly prepare for such case. It seems all the Generals are already on the field. I decided to brief them about the meeting.

"Okay, so we, the CRA Generals, will participate on this war. From what I heard, there will be a United Front of the Clones, as result of Zen Anomalia Recuerdo, Fanbase Characters Guild, and us, being integrated in one group. Knowing him, I'm sure he already has a plan. Regarding our army, we will leave them here to guard Gensokyo. We can't risk being exposed to open attack. Besides, the Outside World already gives their support by sending their army here. Just like what Armageddon said, we should honor the trust they give. I hope this is clear, Mega, Faust, Wesker, Myon, Inaba."

"Yes, Captain!" All of them answer simultaneously. Why Captain instead General? For GUF, soccer is like the second nature, and naturally, we in CRA are affected with that. I don't mind what type of challenge he imposes, as long as I can face him. "Good. Then I'll talk with the UNAF High General." Good thing GUF adopts English as one of official languages. It will make this easier. Iseya Sugaku told me that the whole UNAF is her dear comrades. She abdicates once she knew that Armageddon is alive here, and decides to follow him. At least her connection with them isn't broken.

Since all UNAF aware that flight is common here, this won't surprise them. Instead, I give signal to one of the Generals, asking to talk with their leader. Thankfully, he understands, and informs the High General about it. Learning military hand codes sure is handy, I give Iseya Sugaku that. And just after I land, he walks to my direction.

"I didn't expect you to talk with me personally. We haven't introduced ourselves, aren't we? Then let me start. Maverick Carne, United States General and UN Armed Forces High General." As expected from Iseya Sugaku's former subordinate, Maverick Carne also shares some of her traits. "Indeed. It's my turn, then. Shiro Reimu, one of GUF Guardians and Clone Rebels Army High General." We then shook our hands. For your info, Clone Rebels Army now is GUF Main Army as well. So it's only normal for me to look for Maverick Carne, since he is the High General of UN Armed Forces, Outside World's Main Army.

We talked about the detailed battle plans that derived from the main battle plan Armageddon explains during the meeting. I learned that the soldiers that come along with the UN Generals are only a fraction of the said 67 Field Armies. Even picking the minimal required amount will put it on staggering 6.7 million soldiers! Put it to maximum amount, and you got 20.1 million! On the contrary, CRA only have 10 thousand and more confirmed clones of Gensokyo Faction members. But we make it up with immense strength needed to protect Historia Gensokyo from any and all threats.

"I see… So your army will stay here to defend. Good point. GUF Headquarter is located in this world, and is vital for this war." I nod, and began asking for the full list of confirmed UN Generals. But just before I could do so, I saw Armageddon building something. "Wait, what are you doing here, Armageddon?" I fly to his direction. "Oh, Shirei. About this? We need a movable Headquarter since this is our first direct intervention in alternate universe matter, and a military conflict, at that. It's 67% complete now."

I see… So the Support team will join as well… That is fortunate. He also told me that having a support is very important, because it will be a deciding factor should the conflict reaches stalemate. I remember one of his favorite phrases. "Play the cards, and play it right. Then you will know what to do." He also said that it applies to everyone, not just the leaders. The meaning is, use whatever you have in your disposal, and use it to your advantages. Then proceed to turn the tip to your favor.

Yasei's POV

Now that you mention it, ever since Kasen is confirmed to be an Oni, I almost can't look at her without some puking. I'm not kidding, it dates back just after I beat Yukari. Since I'm still working now, this is the right time to tell you what I mean. By the way, thanks for reminding me of that phrase, Shirei.

October 22nd, 2018, in the foot of Youkai Mountain, Gensokyo (Yasei's Flashback, Normal POV)

'Both Yasei and Yukari bleed heavily, and they already reach their limit. All of a sudden, Yukari falls. The battle is decided once Yasei holds her up. Thanks to his newly obtained Living Radar, Yasei can counter and predict all of Yukari's movements. But since he's still new at it, he still takes some damages from her attacks.'

"Enough with the narration, Yukari. You say that Reimu is missing?" Yasei slightly annoyed by the narration, and tells Yukari to explain the details. She nods, and tells him briefly. "I'm afraid this won't be easy. That's one reason I decided to heal you. You already absorbed the knowledge you need since you completed your Challenge Agenda. All I can tell you is these clues, Darkness of Avici and Touhou Ibarakasen." Using his Memory Connections, Yasei tries to connect both clues, and shocked with the result. "I don't know how I can enter Avici, but I'll manage, somehow. If anything tells me, removing Reimu from Gensokyo is Armageddon." With that, he dashes to Higan.

Meanwhile in Avici, Reimu stumbles to someone that looks like Kasen. "Look like you still retain your initial powers, even after transformed into an Oni. It was awfully rude to borrow it only to trap you here for eternity." That lookalike is identified to be Kasen's missing right arm. "And I also heard that someone actually managed to beat the gap youkai. It's unfortunate that he isn't here… I would like to devour him, flesh and all…" Reimu is shocked when she heard that. She grits her teeth, and picks her gohei. "I don't know what you're planning to do with him, but if what you say is true then I won't allow you!"

Reimu fires a barrage of amulets, but to her surprise, the arm didn't flinch. And it didn't stop there. The arm closing in and throws the punch. Reimu managed to dodge her punch and lands. "You expect to hit me with a punch that sl-" Before she finished, she was thrown back quite far because the shockwave resulting from the said punch.

On the other side of Avici, Yasei apparently managed to mark the entrance he found to his Living Radar Map. He then feels the ground shaking rapidly. "Kh… An earthquake, here?! This scale… It easily reaches 10 Richter minimally. If what I learned from Memory Connection is true, Reimu can't be far!" Soon after the shake stops, he dashes rapidly. That dash speed is as fast as speed of sound, 1 Mach/second! 'Please let me reach her in time…!'

"What kind of crazy strength is that?!" Reimu lie down and tries to stand up. When she finally stands uptight, the arm already holds a stone pillar. Just when the pillar is about to hit her… "!" It suddenly breaks to pieces. Reimu jumps sideways, while the arm furiously throws multiple stone pillars at the intruder, only to see it crumbles. "That's not so nice of you, Ibaraki-douji." Turns out, the intruder is none other than Yasei. His clenched left arm stretches upward, and to the arm's surprise, it didn't show any sign of cut or scratches.

"Yasei!" Reimu exclaims in surprise to notice that it's him who intrudes. "How did you…" "No need to worry about that. Yukari send me. She already gives enough clues for me to find where you are." Yasei assures her that he didn't come without reason. "Typical Oni, always use brute force and proud of their stamina and endurance… Nevertheless, her stat is far above that of any ordinary Onis in Former Hell…" The arm, now identified as Ibaraki-douji by Yasei, smirks when she heard his remark. "So it's true… You're the human that managed to beat Yukari Yakumo outside Spell Card duel. At least you didn't evade my attacks."

Ibaraki-douji then proceeds to hit the ground, but unlike last time, she partly buries her hand. "Here they are, here they are… The unlimited servants of Hell…" As she raises her right arm, she holds a skull. Then, a massive amount of skeletons rose from the ground, as if heeding Ibaraki-douji's call. "Do you really think I'm scared of a pile of bones?!" Reimu fires a barrage of bullets around her, and it hit all the surrounding skeletons. To her surprise, the skeletons somehow managed to connect their parts back. 'I see… Let me check if my theory is true.'

Without wasting time, Yasei snatches a skull from a skeleton behind him, and crushes it to pieces! "!" Again, Ibaraki-douji is surprised to see Yasei's unexpected move, especially since the skeleton didn't move after its skull crushed. "Kh… I must admit, I underestimated you. How about joining them, then? I'm sure you'll make a great skeleton." She then throws the skull she held this whole time, and all the skeletons pulled to the skull's direction. 'Wait… Wait…' Yasei waits until the pile of bones blocks Ibaraki-douji's sight from him and Reimu. 'Now!' Once it blocks her sight, Yasei grabs Reimu and activates his Spell Card. 'Speed Sign "Mach Pursuit!"' Then they escape and sped rapidly.

Ibaraki-douji seems satisfied when the pile of bones covering the crater. She mutters to herself. "Those skeletons are all the remains of the people I've eaten. Looks like I'll have two more servants." She didn't know that the said 'servants' already escaped safely. Three seconds and still no movements, she finally realized it. "Again?! How did that human managed to outwit me?!" If only she hears what Yasei said earlier and not smirks… Without wasting time, she decides to look for them.

"For a second, I feel sorry for outwitting Ibaraki-douji…" Yasei remarks about his move earlier. Breathing heavily, Reimu scolds him. "That's just you! I almost have a heart attack there! Your speed is as crazy as her strength just now!" Reimu wants to hit Yasei, but the latter stops her. "Not now. I already propose a challenge to you, but not now. Right now, Ibaraki-douji already realized my last move. We have to stay here, or she'll spot us." The shrine maiden sighs. "Hide and seek, I take it? Alright…"

On yet different side of Avici, the real Kasen enters. Yasei already notices her, but decides to not make a move. From his Memory Connections, he only needs to take caution of one thing. And it's about to be unveiled soon. Ibaraki-douji is coming closer to Yasei and Reimu's position. She is about to spot them when she noticed that the piles of bone has been exploded. "Wha?!" What's more, someone strangles her from behind.

"Why you…! I almost managed to get that human!" Ibaraki-douji tries to free herself, but to no avail. "If you're going to be like that, then why did I bother bringing your body here?!" The strangler rebukes her and still not lessening the power. That's when Ibaraki-douji seems to recognize the voice. "Could it be…" She then laughs. "Ha ha ha...! What the hell? It's the real one!" Turns out, the strangler is the real Kasen, who Yasei already detects. Noticing it, he gives signal to Reimu. "It's safe now. But don't move a single inch from our position. There's a chance they might notice us." Reimu sighs again, and complies.

Kasen reunites with Ibaraki-douji, and they have some friendly chat. "It's been a while, my dear partner." The latter chuckles and she replies. "Seriously, wasn't expecting you to drop in. Guess I have to thank them. You heard about that human, aren't you?" That makes Kasen surprised. "Wait, Yasei is here?!" Ibaraki-douji rubs her head in embarrassment. "Yeah, and just like what was rumored, he's very smart. Heck, he outwits me twice. Now, you didn't forget me, didn't you?" Kasen closes her eyes and answers solemnly. "Of course not, how could I?"

Yasei and Reimu watches them talking. "Hey, shouldn't we interfere?" Reimu seems impatient to settle a score she has with Ibaraki-douji. "Don't do it, and you'll see why soon." Yasei stops her from acting rashly. That's when it happens. "Come on, partner." Kasen invites Ibaraki-douji, and she complies. "I found you at last." Then both of them say something at the same time. "Let us finally become one again!" Realizing what's going on, Yasei shouts loudly. "Darn! Hit the ground, Reimu!" Reimu is surprised by his sudden shout, and complies. (I wonder if the fusion itself is a danmaku…)

Yasei tracks the fusion process via his Living Radar, and shivers. 'Okay, I'm dead… Kasen is officially an Oni now…' Reimu notices his shiver and asks. "Is something wrong?" Yasei simply points above. Reimu tilts her head and shocked to see what's in front of her. The bandage in Kasen's right arm is gone. Ibaraki-douji disappears, and her essence gathers to form Kasen's right arm. But that's not all. Horns grow in where her buns previously placed. The sleeves are gone, and her hair becomes longer. When the process is completed, Yasei suddenly vomits blood, to Reimu's shock.

Needless to say, Kasen, who regains her true form, noticed it as well. 'So it's true, after all… Yasei is here…' She waits until he stands up, and about to introduce herself. But… "Indeed, I am-" "One of the Four Mountain Devas, Wile and Heinous Oni, Kasen Ibaraki. At least wait until I recover, you know…" Yasei sighs regarding Kasen's eagerness. 'This will be complicated now… What's more, she became even more attractive than the last time! I only can rely on my Living Radar now…'

It's Kasen who is surprised now. She didn't even start, yet Yasei already know her true title. She then noticed the blood that flows from his mouth. 'He says whether he thinks about a female proportion, it happens… But I never expect it to be this bad. And what's more…' That's when she realized it's her who caused it. Naturally, her face becomes red. But she can't be angry to him. 'So that's why… He didn't want to offend us…' Instead, she throws bread to him.

"Take this. You'll need it." Yasei catches it and starts eating it. Reimu is surprised to see that. "Wait, how about me?!" Kasen tilts her head and answers. "I have no business with you right now, Reimu. You're free to go. Besides…" She then looks at Yasei and grins. "I'm interested to see his skills, since he already beat Yukari." Noticing the signal, Yasei looks at Kasen and returns the grin. "First, confirmed as one of Gensokyo Sages, then one of the Four Mountain Devas… Just great, I already faced Suika as well, just so you know." There's a period of silence before both Kasen and Yasei challenges each other.

"Fighting you while you're weakened like that wouldn't be fun at all. When you done with the recovery, feel free to come at me with all you got. Let's see how much you grow, after completing the Challenge Agenda you sent to Reimu, Yasei." Kasen lands after she says that. She's probably aware that Yasei can't fly, and decides to fight on the ground. Yasei replies while sits on the ground. "Interesting, isn't it… I'll make sure to gather your data, just like Hijiri, Suika, Satori, Iku, Miko-kun, Tenko, Udonge, Kokoro, Youmu, Yuyuko, and Yukari. You'll be the Extra Boss of my Challenge Agenda, Kasen." Both of them grins again, and soon, Yasei stands up and facing Kasen. Their fight is about to begin…

Present Day (Normal POV)

Yasei finally finished building the movable Headquarter. "That took longer than expected… The flashback, I mean." He pukes when he detects a familiar presence. "See? She's more gorgeous as an Oni…" Then a chained iron ball sweeps from behind him. Yasei grabs the chain and throws it to a clear area. He's not surprised to see a familiar face from his flashback, as she lands gracefully, for an Oni. "Seriously… Just when you would stop puking when you detect me, Yasei…"

Right, she's none other than Kasen Ibaraki. She's one of the Gensokyo Sages as well as one of the Four Mountain Devas. "Can't be helped, Kasen. You already listed as one of my greatest rivals in GUF alongside Yukari, Shirei, Reimu, Lithnanai, and Lucy. Besides, it's me who should ask you to get some sleeves for your tabard, for God's sake! Didn't you hear what I just said before?" As per usual, every time Yasei mentions Kasen's attractiveness, the latter blushes.

"That's beside the point. Are your pets with you?" That makes Kasen intrigued. "It's rare for you to ask me about my pets. Do you notice something?" Yasei nods, and materializes a paper that has some writings in it. "This paper is the note from my Memory Connections. I'm sure you'll understand once you read it, as one of Gensokyo Sages." He then calls both GUF Elites and Support team, informing them that they are needed in the field.

End of Memory Connection Note

While Kasen reads the note, Yasei talks with Shirei and Maverick. He also calls the GUF Elites and informs the Support team that the movable Headquarter is completed. "Wow… UN is serious about this… The Generals are coming from different nations…" Like LT on the meeting, Yasei is stunned as well. Only, he's stunned from the diversity of the Generals' homelands.

Yasei's POV

Oh, right. I need to tell Izayoi-kun to call all registered Outsiders Guild leaders. Luckily for me, he also has Augma as well. Then I turn on the Augma. "Can you hear me, Izayoi-kun?" Needless to say, he replies right away. "Yeah, literally. Technically, your hologram shows up on my Augma interface." I burst out a short laugh. "Right… Anyway, you know what this means, right?" Izayoi-kun is right about one thing. His hologram shows up on my Augma interface. "Got it. Kirigaya and Tomoe already went to the field. Wait, shouldn't you ask Thesda instead of me?"

He's right again. On the period of Historia Alliance Formation, Lucy challenges Izayoi-kun, and managed to win, thus makes her the current Rank 2 of Outsiders Top 4. "I also intend to shift the baton to her anyway. Consider this my last assignment as Advent Outsiders United Vice-Leader, Yasei-kun." Living in Gensokyo sure makes him softer. "Okay, Izayoi-kun." Then I turn off the Augma.

So Kazuto and Mami Tomoe already on the move… Right, Vaati told me they came here before the rest of us Outsiders. Sanae already gone native, if that's what you ask. And the Danmakufus? They're natives as well, according to Reimu. That reminds me… UN already gives their support by sending their Field Armies. Yeah, I know I said that war declaration applies to all Historia Alliance members, but I don't want to burden them for now. I already have Yori's (Yorihime) contact, and Iseya got Miho's. Then I pull out a smartphone. Seems outdated considering the year we're in, isn't it? And I called her. There are a lot of callings lately. It must've been the effect of that declaration. Thank God she connects right away.

"Iseya, I have a favor to ask you." She seems surprised to hear me say that. But then again, it is rare for the GUF to hear me asking for a favor. "Yes, what is it, Onii-chan?" Here we go… "It's regarding Miho. I don't want to burden the Senshado League for now. Can you relay a message to her?" We both fell silent. Right… We both are reminded with that war, Final Armageddon Warfare. To be honest, the cause is more to my own doubt regarding Catholicism doctrines in Christianity. Let's not go there, shall we? I'd rather not tell anyone outside GUF about the real reason of it unless if I have to.

"I see… Does that mean you will need them in the upcoming battles?" I'll give her that. We both aren't related by blood, yes. But the bond we have… That reminds me with a verse. 'There is no greater love than those who gives their lives for their friends.' Sparing Shirei and her army is one thing, since I can tell she just want someone to understand her. But realizing that Iesua-san isn't that perfect? True, it did shock me, but eventually I'm able to accept it.

Why? I decided to look at her info that I've neglected to read. Apparently, her backstory is quite tragic. And let me warn you that this might offend some Outside World believers, so take this as Gensokyo history lesson. Why again? I'm Christian now. And I even made it official in GUF that no one should offend any religions and its believers. Seiga tries it once, and that result in me coming personally after her. Trust me. It's not pretty at all. I'm not offended if she says it out loud to me, but for her to offend Yuuki, as in Yuuki Konno, and Arcluz as well… That, I can't let it stay that way.

It results in formation of 'Gensokyo Faith Defenders'. Reminded with Europa Universalis, aren't you? That's because it's exactly what you think it is. That means, I met personally with Kanako, Hijiri, and Miko-kun to discuss about this topic. They are surprised to hear that I become a Christian, but they understand why. Someone has to represent the Christian Faith, and I'm willing to do anything to prevent religious wars like Final Armageddon Warfare from happening again. Then it's official. Kanako is Shinto Faith Defender, Hijiri is Buddhist Faith Defender, Miko-kun is Taoist Faith Defender, and I'm the Christian Faith Defender. Now let's go back to the original topic.

One of Iesua-san's Spell Cards, "Eli, Eli, Lema Sabachtani", is actually based from one of Christ's sayings on the cross. It literally means, "My God, My God, why have You forsaken me?" From what I read, in another reality, (not Universe, reality) this results in Iesua-san losing her powers once, because that saying means she blasphemes God, and thus became mere human. No wonder Reimu declares Wicked Star Incident as closed. Because it's the conclusion of that story, and signs the start of Danmakufu Influx of Incidents. Mind you, Historia Gensokyo has two sets of Influx of Incidents that Reimu has to work very hard to resolve until my arrival in 2017.

I hope that will tell you enough about the reason why Final Armageddon Warfare happens. I'm actually surprised to see that MSS has some Christian believers, meaning Tsurubami didn't oppress the religions in Mugenri, which is good for them, and one of reasons why GUF allies with MSS, despite their Socialist ideology. Let's go back to the call. "Yes. Tell them to have two sets of annihilation matches against UN Army tankers. I know you trained the whole UNAF before, and I really hope the Senshado League will be in top form in the upcoming battles. We will need them like that time."

To my relief, she got what I mean. "Alright, Onii-chan. Say, shouldn't you call Yorihime-san as well?" There it is. She finally asked about that. "Don't worry about Yori. I'm sure she will get the message and decide when it's the right time to intervene." I can say that because I actually faced Yorihime myself before. "Got it. Best of luck in the battlefield." We both turn off our smartphones.

Mark's POV

Earlier on the meeting, I feel uneasy when I heard Dad confirms that BLA intends to destroy HMF. And since I also have Living Radar like him, Dad decides to let me think the best course of action for our group, Neo GUF Guardians. What both I and Dad can agree on, is the fact that the Neos are more capable of recon operations. And that's what I intend to tell to them. Good thing I already gather the First and Second Squad members.

"So, why we're here, Mark-san?" Unusual for her, Izeka is the first one to speak. That reminds me… The Neos are basically bunch of siblings grouped together, minus Rozie. "It's about the current situation. I'm sure you also heard about it, Izeka. BLA already made their move just after Dad done tells the battle plan to LT-san and Tsurubami-san. With that in mind, I need to do Ability Check to all of you." Ability Check… One of many functions I can use with Living Radar. Dad told me that he created it by fusing Satori-san's Mind Reading, Iku-san's Atmosphere Reading, and Miko-san's Desire Reading. And since I inherit it, that means I'm his firstborn. I also inherit Mom's Loophole Detection as well. By the way, Izeka inherits both Iseya-san and Izayoi-san's combat skills.

"I see… Good to see you finally able to grasp your ability, Aniki." Kazei… He's among the first one that knows about my Living Radar. He can control momentums. By momentum, just picture Dad punching Yukari-san's train during his duel with her. That means Kazei can partially control speed and force by changing the values. "Thanks for that, Kazei. It's the same for Mirai and Shinano as well." Why I said that? It's because Mirai and Shinano are Kazei's younger siblings. Speaking about it, Irami and Nagano also qualifies, since they're Izeka's younger siblings.

Quick summary for their ability is as follows. Like Sanae-san, Mirai can invoke miracles, though she still isn't near Sanae-san's level. Irami, just like Dad, can create inorganic materials out of thin air. Rock, soil, metal, mineral, anything. That means he also can create weapons and arsenals in the same manner. The only drawback is, his combat skill is not as good as the rest of us, though I won't say he's bad. He's actually quite good in it, only he suits better for supplying our materials, with Dad providing majority of GUF materials. About Shinano, he's the best when it comes to technological improvements. And I should tell you that he's also quite a nerd when it comes to arsenals. I kid you not. Last is Nagano. One thing you will need when it comes to recon operations is ability to find any signs of traces. And she has exactly that. She even knows the owners of the traces just by looking at it.

"That's good and all, but don't you think you need some nature support, Mark?" That's Seth. Mind you, Seth here is she, unlike the biblical version. "Right. And you're the one who will do it, Seth. You already learned Kasen-san's and Yuuka-san's abilities, after all." It's exactly what I said. She can connect herself to the surrounding nature, particularly animals and plants. Seth basically combines Yuuka-san's Flower Manipulation (which she already improves to Botany Manipulation), Kasen-san's Animal Guiding (which she already improves to Zoology Manipulation), and Iku-san's Atmosphere Reading into another Ability Fusion that she dubs as Nature Connection. My Living Radar is inherited from Dad, as I said before. One more thing, Seth also able to use Elemental Powers because of said Nature Connection.

"That aside, Kureha, Shinsei, in case there's something I couldn't detect with my Living Radar, tell me." Both of them nod. "Got it, Nii-san." If this continues, you know where it went… Something Dad rather not focused himself on. Anyway, Kureha has stronger Aura Manipulation than Shinsei, but the latter is more suited for combat. Also, Kureha is the Priest, while Shinsei is the Shrine Maiden. One hint for you, both of them are the next Hakureis.

Next in line are Jikan and Kukan. Something tells me that they still improving their abilities until now. As stated by their names, Jikan inherits Sakuya-san's Time Manipulation, while Kukan inherits her Space Manipulation. I know Komachi-san also able to use it, but the reason why Sakuya-san is stronger is because she also has time on her side, literally. Then I call them. "Already done?" Suddenly, they appears, and they seems embarrassed, probably because the fact that all Neo GUF Guardians are immune to their abilities. "Right. Sorry about that." Well, you don't have to be that sorry. If anything, the faster it's done from the other's perspective, the better. "Don't mind about it. As long as you don't bother anyone, we don't mind." Exactly, in fact, we even encourage them to improve their abilities.

Finally, the Single Entries. Jigen, Kekkai, and Maria. Again, for Jigen and Kekkai, their abilities are stated by their names. Jigen's stats are far above that of Izeka's, despite he's being younger than her. If there's one thing that I can tell you regarding him, he's the result of experiment conducted by Dad and Iseya-san. Know In Vitro Fertilization? Apart from that method, they also add their dominant gens to it. Dark, isn't it? But don't worry. Eirin-san supervises the said experiment, so it's fine. Kekkai, on the other hand, inherits Yukari-san's usage of gaps and barriers. I heard Richard-san from UGF also has gap manipulation, but he leans more to combat spell caster. Kekkai here is our defensive support member, and a very vital one, at that. You know why. He can report back to the base simply by teleporting himself. Maria… Just like Marisa-san, she's quite brash. But at least she shares her mother's hard worker perk. Another thing they shares is their abilities, with Maria leans more to explosives usage. Grenadier, saboteur, anti-armor, just leave it to her.

Last is Rozie. Like I said, she's the most veteran, so she has more experience compared to all of us. She has decent swordsmanship and Hostile Presence Detection. She's even the oldest on our group! Oh, I almost forgot one thing. I also have one other ability apart from Living Radar, just like Dad, though he has two instead. While Dad has Speed and Rage Manipulation, I have Vortex Manipulation. By that, I mean controlling any rotary movement. Tornado? Check. Hurricane? Check. Firestorm? Check. Ice Storm? Check. Whirlpool? Check. I mainly use it for defensive purposes, so no worries.

Before I finalize it, let me tell you few things. Neo GUF Guardians has few twins to note. Both I and Seth are one. Next are Kureha and Shinsei. Last are Jikan and Kukan. Kazei and Izeka have some special privileges. Here is what I mean. Kazei - Mirai - Shinano and Izeka - Irami - Nagano. This sign (-) means one year older. So, basically, the cousins (Kazei=Izeka, Mirai=Irami, and Shinano=Nagano) are born at the same time. I already explain about Jigen, Kekkai, Maria, and Rozie. So we can skip them. This is the summary of our current age, sorted from the oldest. I also input our genders as well.

43 (as of 2055): Rozie (F)
20 (as of 2055): Mark (M), Seth (F), Kazei (M), Izeka (F), Kureha (M), Shinsei (F), Jikan (F), Kukan (M), Jigen (M), Kekkai (M), Maria (F)
19 (as of 2055): Mirai (F), Irami (M)
18 (as of 2055): Shinano (M), Nagano (F)

"Okay, I already completed the Ability Check. And speaking about which, our actual first mission is to help HMF rebuild itself and still ongoing as of now. Then Neo-Gen Conflict almost hamper it. Almost, but thanks to Dad's diplomatic skills, it ended with minor damage to Pacific Ocean. I'm not kidding. Dad may be the strongest in GUF, but he also knows that strength isn't everything." Mark almost over talking there, but he stops himself with a cough. "Sorry. Where are we…? Oh, right."

Mark then explains their role as recon team now that GUF joins HMF in their conflict once again. While they do participate in the rebuilding, that wasn't a wartime mission. This time, however, they can show their full potential. And he knew that sooner or later, he will need help from other Neo GUF Guardians Squads.

Kasen's POV

… I see… So that's what Shiro Reimu felt when Yasei spares her and the rest of CRA… Another chance to redeem yourself… I thought he would end me like what happens a thousand year ago… But I was wrong. He also struggles to keep his carnal desires, which he dubs as Yami Yoru, in check, just like that time when I struggle to get full control of my body from her… And luckily for the Higher Echelon, they just need to look at my eye color to determine whether it's me or her who controls this body. Since he already having a flashback about how I found out about his carnal desires, it's only fair for me to do the same about how the battle went out. But still, I don't expect him to think I'm alluring… No wonder he is very anxious that time…

October 22nd, 2018, in depths of Avici, Gensokyo (Kasen's Flashback, Normal POV)

"Kh…" Yasei holds his left arm while his eyes closed. He was in Blind Fighter mode. As strong as he is, he is still human. And this fight proves it. 'Both Suika and Yuugi weren't this serious… So this is the real power of a Mountain Deva…'

"It seems like you're not giving your all. I wonder if that bread wasn't enough…" Kasen half-mocks Yasei, but the latter didn't respond at all. "Hmm?" Obviously, she became curious. 'What was he thinking? I can't seem to grasp his planning…' For some reason, she can't read what was in his mind. 'Never expect it to work wonders… Not only I can check my surroundings without worrying about invoking it, but it also prevents the opponent from reading my mind. But I feel like there's something familiar about this… It's as if…'

In shock, Yasei opens his eyes. 'There's no mistake about it! Kasen also faces the same trouble I'm facing this whole time. I made a self-pact to contain my carnal desire, while she found out that Ibaraki-douji is still as malicious as she was millennia ago. This is more complex that I thought…' Just when he opens it, Kasen tries to hit him, but he dodges to the left, and performs a back volley kick using the propulsion from the said evasion. "… You and your stunts… Still, that does give me shock damage. Not bad for a human." Yasei only sighs deeply in his mind. 'It seems she doesn't know what parkour is…'

Unbeknownst to Ibaraki-douji, who now controls part of Kasen's body, the latter monologues in her mind. (Note: It seems there will be another telepathy conversation here… The battle is still going on, but it'll be more even, since Kasen now fights on the ground, unlike in WaHH. And the plot differs as well.)

'I've always been looking for her, the arm I lost long, long ago. All of my malice was forced into her, and sealed away. Along with my malice, I lost all interest in this hellish reality. I became a hermit, one who strives for another world. But, it's not as though she was completely destroyed. Still filled with malice, she waited for the seal to weaken.'
'! Wait… Is that…?!'
'?! Is that you, Yasei?'
'Yeah… You know, Kasen, your stats ramped up ridiculously high, so much that my left arm paralyzed when my fist met yours.'
'I see… I assume this is your 'Living Radar'. Good job on finding me.'
'Save that for later. Any clues you could give me?'
'Just another monologue. Do you mind?'
'Not at all.'
'At long last, I finally found her, in the Outside World. She… was left neglected, on display at some run-down old temple. As expected, her seal was nearly undone. It seems she have already eaten numerous people. So to secure it, I took her to Gensokyo, where I tried to reseal it. However, that was a grave miscalculation. In actuality, her seal had been placed on my own body, not on herself. I realized that she alone couldn't be resealed or destroyed.'
'… I feel like it could emerge at any moment… My carnal desires, that is.'
'! So that's why you spitting blood earlier…'
'Right, and that's not a pleasant one. This might sound crazy, but I have a plan.'
'… I'm actually going to ask what your plan is, but somehow I know already… That carnal desire of yours… I feel that it can become sentient in the future, whether you suppress it or not.'
'I'd rather suppress it, but if Ibaraki-douji gone berserk… Then I have no other choice.'
'… Letting you cop a feel on my breasts…It might shock her, but I'm afraid that won't be enough. In order to reseal her, you have to defeat me. And it must happen just like a thousand years ago… when I lost my arm to the Youkai Blade Onikirimaru.'
'Onikiri… Wait, did you say you left an onigiri for Reimu?!'
'Right, but I decided not to bring it here, since I heard that Reimu became an Oni just like me. You, on the other hand, are still human. To be honest, I didn't expect you to foil my plan already. I only can hope someone managed to find it and bring it here…'

Around the same time, Tenshi suddenly appears next to Reimu.

'Tenko… I'd say she's the key for this. Shall we halt it for now?'
'Might as well. You know what to do.'
'Got it.'

True, to Tenshi and Reimu's surprise, both Kasen and Yasei stops suddenly.

"Wait, you're here already?" Tenshi is surprised to see that Yasei also in Avici. "Yeah, I was sent by Yukari. She says since I already beat her, I have the right to decide how we will resolve this." He explains the reason why. "That's ridiculous!" Reimu didn't seem to believe what Yasei said, but he isn't surprised. "I know, right? Just ask Yukari yourself after we're done with Ibaraki-douji. Anyway, did you found anything of use, Tenko?"

Tenshi and Reimu didn't know that Yasei just had a telepathy conversation with Kasen. Needless to say, they look at him with a confused look. *sigh* "Got any onigiri? I'm hungry again…" Upon hearing that, Tenshi grins. "So you found it out… Here. I found it at the shrine. Look like Reimu is only interested in the arm, so when the banquet is over, I decided to take it, since I feel she might need it." Just after that, Reimu yells loudly. "How could I be hungry at a time like this?!"

Waiting until the 'discussion' over, Kasen holds her right arm. 'I originally planned to train Reimu so she could help me reseal this arm. But when I heard that she became an Oni after hearing a shocking truth, I desperately need someone to replace her. Then you came. Unlike Reimu, you're a real hard worker, so I don't have to worry about training you. And hearing your training helps you won against Yukari outside Spell Card Rule further affirm it. Furthermore, you even found out about my plan.'

Yasei then unwrap the bamboo leaf, and when the onigiri fully unwrapped, he feels something heavy underneath it. "You're right. Sorry about that 'hungry' part. That's just a farce." It's Reimu who surprised now. "Eeh?! So you don't need the onigiri?" Yasei nods, and pulls out something between the wrappers. It's a piece of metal, but since Tenshi says it might turn the tide, he decides to take it. "This is what I need." To further affirm his point, as well as checking whether it's Kasen or Ibaraki-douji who currently controls the body, he points it to her. 'Let's see who was affected by that.'

Turns out, it's the right arm that twitches when Kasen looks at the said piece of metal. "That… That shine… No way! Is that a fragment of the Youkai Blade Onikirimaru?! What's that doing here?!" Yasei grins when he heard that. "Got you, Ibaraki-douji." Then he places the fragment of Onikirimaru to the magazine box of his modified Desert Eagle. The said magazine box didn't have any bullets, but instead filled with crystals for non-lethal measure.

"This might be unpleasant for both of you, so please step back. I might do something unthinkable when the fight begins. And I'm sure you don't want to think what it is, since I'm a boy…" Surprised to hear that, both Reimu and Tenshi steps back. "Are you sure this is really okay?" Reimu asks Tenshi, in which the latter replies. "I don't know… But if there's one thing I'm certain about, it's that he already have a plan for it. Besides, he already beat me as well." Reimu seems prone to surprises now… "Even you too?!"

'Okay Kasen, I got what you mean. Brace yourself. I might do what you suspect.'
'Alright, she might go berserk upon realizing it. I'm counting on you, Yasei."

The light on Kasen's eyes are gone as they done strengthening their resolves telepathically, signaling that Ibaraki-douji now has full control.

"I see. So my main body hid that trump card. Betrayed by my own self… What a sad story. Then from now on, I, the arm, will just have to take full control of Kasen Ibaraki." From the tone of her voice, Yasei knew that this malice will stop at nothing, since it can never be satisfied. "You're not the only one who can do that, Ibaraki-douji." As he done saying that, his voice changes. "I must admit, you're quite strong, for someone with such alluring body." Needless to say, both Tenshi and Reimu are shocked to hear Yasei saying such things. "So that's what he means by 'unthinkable'…" They thought that he might turn to a combatant rapist, while in fact the carnal desire took full control over Yasei's body, just like how Ibaraki-douji took full control over Kasen's body.

Since their bodies are taken over by their other selves, Kasen and Yasei continue to talk telepathically.

'What will you do after your carnal desires dried out?'
'When that happens, I'm afraid I can't grant your wish.'
'What do you mean?'
'I have three reasons why. First, sure, I can detach Ibaraki-douji, but I don't intend to seal her. And I don't think Reimu can- actually, she can, but who knows what will happen. It's not like I don't want to, but I don't know what will happen if I forcefully trying regardless.'
'You have a point. She couldn't be destroyed, and her seal is placed in my own body. What's next?'
'Second, no offense to your path as a hermit, but I think it's too… cruel, even for someone as malicious as Ibaraki-douji. If you ask me, I'd rather have my carnal desires exterminated, but I decided not to. Why? I only start to get it ever since I enter Gensokyo. And you know what I mean by that… That's why I keep suppressing it, even though I know it's inevitable and have a bloody cost.'
'Is that connects to your final reason?'
'Yeah, and to be honest, I agree with Yami Yoru. That's the name I choose for my carnal desires. You're so alluring… I think I also told Yukari about this, but I'm more attracted if there's a well-endowed girl or woman with long hair. Huft… And right now, you qualify for both, since you don't have any sleeves (for the alluring one). I don't know if this makes me a pervert or not. All I can do for now, is to make sure to keep him in check. The truth will reveal itself, whether we like it or not.'
'They already know that I'm an Oni, but they probably would never expect this… You're right. Detach her, and I'll take care of the rest. You also want to confirm your other theory, right?'
'You got me. I want to know whether you can return to your normal form after she detached or not.'
'Then it's settled. I might need her strength in the future, whether I like it or not.'
'I feel you. I might need his strength as well in the future, whether I like it or not.'

Both of them stop midway upon hearing each other's synonymous line.

'Look like we're thinking the same thing. Want to say it together?'
'Sure. Yoru's time here is about to end, after all.'

Back to the reality. To Reimu and Tenshi's shock, despite the fierce fighting sounds, they could hear two different voices, saying the same sentence. "Whether we like it or not, we won't trash away our other selves. No matter how malicious or carnage they are, they are still part of us. And we intend to keep them, because we might need their strength in the future."

As if responding to the said voices, both Ibaraki-douji (Kasen) and Yami Yoru (Yasei) stops abruptly. That alone is enough to repel them out. Kasen looks at her wounded right arm, signaling Yasei to shoot it. The latter nods, and then proceeds to shoot multiple times. Sure enough, the right arm wriggles itself out, and reveals Ibaraki-douji, now full with wounds. "Kh… How could you…" She then passed out.

Yasei only sighs, and says something. "She must've never heard about enchantment. I just put the fragment of Onikirimaru to my Desert Eagle magazine box, and the bullets fired now have same property with it." Kasen shook her head lightly in disbelief. "Probably she also never heard about parkour. So, what do you think about… You know… My breasts?"

Yasei fell silent for a second. 'Never thought she actually remembers it…' He sighs and tell Kasen bluntly, not even bothering to lower his voice. "How should I put this, I don't know what to say, apart from the firmness. Sorry for making you hear about my ridiculous plan. The first time I ever grope someone… So my theory confirmed…" As he said that, Ibaraki-douji returns to her initial form, an Oni arm.

"Right, and with this, I don't need to worry about her. All that's left is to bandage this cut arm again. If she does go berserk again, can I count on you?" Yasei is about to reply, but Reimu interrupts. "Hold on, what do you mean by bandage that arm again?" Kasen picks up the arm, and reattach it, to her surprise. "Wait, what you're doing?!" Kasen didn't say a word, but instead applies the bandage so it covers her whole right arm. "I figured it might be better if I keep her under check. Besides, everyone already knows that I'm an Oni, but Yasei only realized it now. Might as well letting him get used to it."

On closer look, Kasen indeed returns to her normal form. Earlier, her tabard was black and golden, and her skirt was white. Now, the tabard is maroon and the skirt is green. Somehow, the sleeves are back. You could see that she has little horns on the bun spot. (Note: Congrats to Vaati Star and everyone who thinks Kasen is an Oni. It's true, and Vaati even suspects the bun hides her horns, which turns out to be true as well. Do note that I pick Fugere Timeline as one of the basis for my stories.)

Warning, fourth wall breaking conversation is about to commence.

The group then talks about how it should happen in the canon version (aka Wild and Horned Hermit) while they made their way to return to Gensokyo.

Yasei starts with his Memory Connection. "Reimu is supposed to be the one who cut Kasen's right arm and reseal it, but since she's an Oni here, the plot didn't happen. Must be the Butterfly Effect Yukari told me about. To be honest, it already happens ever since Vaati enters Gensokyo, before this Influx begins. From there, it's only a matter whether this Gensokyo can hold on or not. Luckily for us, it still holds on. The flow went as usual, albeit with some ebbs."

Tenshi is the next in line. "Yeah, I didn't expect that one. The Hakurei Shrine Maiden is an Oni now? No wonder she has that ridiculous strength. But then again, it happens back during the First Scarlet Devil Tournament. Speaking about which, you do won a tournament once, right?" Nod from Yasei. "Winning a tournament sure gives some prestige for a Gensokyan. Another way to get it is by challenging someone to a fight. And the said someone must be well-known. If you win, you get that prestige."

Reimu barges in. "No wonder you send me that Challenge Agenda... From the look of it, the first five, Byakuren, Suika, Satori, Iku, and Miko serves as your way of training. Afterwards, it's actual challenge using MUGEN System. That one system that lets you challenge anyone without Spell Card Rule, and still without fear of dying… Pretty convenient for any competent Outsiders like that of Kazuto Kirigaya and Mami Tomoe."

Last is Kasen. "I guess that makes Yasei the first Outsider that also managed to create Spell Cards, then. Vaati basically uses Patchouli's Spell Card arsenal, so she doesn't count. Our fight can be considered as part of his Challenge Agenda, although impromptu. Fitting, since from what you said, there's only 11 people written, with the latter six, Tenshi here, Reisen, Kokoro, Youmu, Yuyuko, and Yukari are the real challenge according to him, with me being the Extra Boss… Making you think about the main games setting… 6 main stages and an Extra…"

(Note: If you ask where Ibaraki-douji is, she's bandaged to Kasen now. Like I said, the plot altered here.)

End of fourth wall breaking conversation.

Back to the shrine…

To their surprise, many waiting for them at the shrine, in particular Marisa, Sanae, Sakuya, and Youmu. "What happened?" Sanae is the first one to ask. "Just facing a berserk Oni in Hell. I can say that Kasen helps in it." Yasei actually want to cover for Kasen, but decides to shred a light of truth. "Right, and it wasn't an easy one. Then again, you all already know that I'm an Oni. The AU Gensokyos might not aware about this. But our Gensokyo does. Need an Oni to know another, am I right?" Kasen winks and Yasei returns the favor.

"Is Reimu alright? She seems… pretty beat-up." Marisa unexpectedly shows concern about Reimu. "I'm fine… The fact that there's an Oni able to make both me and Kasen got a hard time is what worries me. It's definitely not Suika or Yuugi." Reimu was shouldered by Tenshi before she then proceeds to enter the shrine. "Don't ask why. That's very exhausting, and I could use some rest."

When the situation calmed down, Yasei was called by Kasen to talk in private.

"What will you do from now on? I will start training myself to contain her until she's completely under my control. Don't want a reenactment of what happens a thousand years ago." Again, Kasen holds her bandaged right arm, which is Ibaraki-douji. "I might need some replacements, though…" She laughs when saying that. "True… I might be able to buy you some bandages in the village. About Onikirimaru, I think I'll try to find other fragments and then bring it to Goto-san. He's the village's elder blacksmith specialized in holy weapons, so I figure once I gather all the fragments, I'd ask him to re-forge it in a new hilt. Also, I already set my target." Intrigued at Yasei's decision, Kasen asks again. "So, who will you challenge next?" Upon hearing that, he grins. "Touhou Top 4."

Present Time (Normal POV)

"Oh, are you done, Kasen?" Now that Yasei finally able to control Yoru, he no longer worried about his carnal desires. Plus, he's Draconian. "Indeed. You know, nearly every other GUF members are against forgiving Clone Rebels Army. Regardless, you decided to do so, and guess where we are… Not like I'd blame this war as your fault. I understand that we must stand with HMF as allies." The form Kasen took when she approaches Yasei earlier is her true form, and that's why he pukes when he detect her.

"Thanks for that. Taking a path to its extremes… I've chosen to spare every opponent I face, to the extremes… It's that extreme, to the extent of No Killing Code that I propose to GUF Higher Echelon. It seems ridiculous, but I then explain it's exactly why we're called GUF, F as in Fighters, not Force. By sparing your opponents, it allows you to train harder because the said opponents might come back stronger. In short, the stronger they become, the stronger we become as well."

Just about time, Shirei decides to join in. "One reason why I pledge my allegiance to Armageddon. He always sees himself as challenger, not the champion. Not many people have that spirit. You could say that Ippo Makunouchi from Hajime no Ippo has that spirit, as in his own words. Being a leader of this Union sure is hard, but he keeps going on. I don't regret my choice. Rather, it's an honor for me and the whole Clone Rebels Army to be part of Gensokyo Union Fighters."

Meanwhile, in UNAF side, Iseya checks the Generals line-up. "All good?" In which the Generals stand up and salutes Iseya. "Yes, sir!" (Told you. One reason why UNAF Generals also salutes Yasei is because his rank is higher than Iseya now, with the former as Zen Captain, while the latter is Rank 4 of Outsiders Top 4.) "Alright then, I have something to say, and it's very important because some of you might not like it." Upon hearing that, as she predicted, some of the Generals feel uneasy about the coming topic. "I know it… Regardless, we shouldn't let our prejudices get the better of us. And do remember, this is like the last war we faced, though this time, we have allies as well. Many said that Trans-Dimensional Warfare was the deadliest conflict in our world ever since World War 2, with few even said that it's World War 3. And for HMF, it's STICK War, which they dub as 'War against Humanity'. In all likelihood, both we and they share a bond. Before I proceed, I need to tell you this, since this might not be pleasant, and Rick already aware about it."

As if waiting for the signal, Maverick speaks. "Before that, General, the Security Council just asked me to relay this message to you." He proceeds to give a letter to Iseya. "… The Security Council, huh… Now all 15 members are permanents ever since that time… I assume it's about my absence throughout 2020 to 2040… Alright, I'll read it." (Note : I know in last chapter I stated UNSC permanent members already, but I think it won't hurt to see how this UN differs from ours. So, like Iseya said, all 15 slots in their UNSC all filled by permanent members. Let's do the roll-call. United States, United Kingdom, France, China, Russia, Germany, Italy, Japan, Australia, India, Mexico, Brazil, Israel, Egypt, and Indonesia. Surprised? I actually didn't expect that as well, especially the last one. This is just my opinion, though.)

Contrary to her expectations, the letter wasn't about forced resignation, but rather, a rank promotion that effectively makes her the de-facto leader of UN Military. (That means World Senshado League also integrated to UNM.) "… What does it say?" Needless to say, the Generals waited until Iseya has done reading the letter. "… I just promoted… to Grand Marshal…" The said Generals gasp simultaneously. Everyone knows that 'Grand Marshal' rank only used as ceremonial rank, but if it's used officially, that means whoever the rank holder effectively got the whole UN force on their disposal. In military history, only nation leaders can use that rank. And to note, this rank is even higher than 'Field Marshal', which in itself is placed higher than 'High General' in UNAF. Knowing what it means, the Generals salutes once again. And as expected, Yasei overheard the said news as well. 'Congratulations, Iseya… Now you held the highest rank ever inaugurated to any military officers, and thus makes you de-facto leader of UN Military… Looks like I don't have to worry about you anymore.'

(Note: Iseya's rank before the promotion is Field Marshal, but because of 'Frontline General' trope, she's usually called as General, which in this case, being translated to Japanese as 'Shogun', her nickname back in UNAF.)

Founding new vigor, Iseya then resumes her explanation. "So, as I said before, some of you might find this unpleasant, but two of HMF members are the one we considered 'taints of history', the Nazis and the Soviets." Once again, the Generals gasp. Maverick then explains the reason. "I actually went to the meeting, albeit briefly, and Zen Captain is kind enough to give us the data of HMF members. As Marshal said, the Nazis and Soviets are there. And that's exactly why she told us to not let our prejudice get the better of us. Remember, we're not fighting at home, unlike last time. This time, we're helping HMF as a member of Historia Alliance. So, if any of you still hold resentment towards them… At the very least, please hold it until we're back."

It became clear as day who thinks that the idea of working with the Nazis and Soviets are unpleasant. Noticing it, Iseya does a roll call.

"Germany, Krieger Comm. Germany, Heckler Koch. Russia, Forse Alkov. Russia, Odyat Vikov. Austria, Glock Steyr. Czechia, Divu Devíti. Slovakia, Veľký Moc. Poland, Waltera Lucznik. Netherlands, Beaumont Karabijn. Luxembourg, Sola Societe. Belgium, Herstal Belgien. France, Bayonne Étienne. Denmark, Dansk Madsen. Norway, Krag Kongsberg. Finland, Lahti Valtion. Ukraine, Fort Makariv. Estonia, Arsenal Tallinn. Armenia, Vahan Hrazen. Azerbaijan, Yirtiji Mubariz. Georgia, Delta Svetvari. Israel, Negev Sharon. Israel, Dror Haganah." (Note : I bet on her stay in Gensokyo, Iseya learns basic mind reading from Yasei.)

The called Generals flinch. They probably didn't expect that each of them would be called using their countries' respective languages! Then, Iseya began her first speech as Grand Marshal of United Nations.

"Truth to be told, I was part of the joint strike team composed of GUF and STI members during the STICK War. Our mission there was to secure victory for HMF, which is rendered helpless because STICK Army's superior technology. And we succeed in doing so. Back to the topic at hand, I probably wouldn't be able to entirely remove your sentiments, but like I said before, please, don't bring our Earth sentiments to HMF. They already faced something similar to ours, an external threat. We wouldn't want UN relationship with HMF strained just because difference in history. And that's exactly why we're called here. To respond to our brethren in another universe, that is our responsibility. So, I can only ask this. You all are free to decide. Just know this, if some or all of you can't stand it, we won't hold resentment towards each other. One can't force another to follow them. That's what I learned from my brother. On that following topic, we won't force World Senshado League to help if they are unavailable. It's our fight, and we aren't alone. HMF already accepts our offer of help, and right now, we all are put under GUF command. We won't do this to gain reputation, no, we're doing this because it's the right thing to do. Anyone who fought against the righteous cause shall not be spared. That means those that decides to break Geneva Conventions will pay for the cost. There won't be another World War under our watch!"

Unexpectedly, the respond came in various army slogans chanted in successions. After that, Iseya realizes that this will be just like 2010, when dimensional forces attacked their Earth. Knowing what she needs to do, she contacts the current UN Secretary General.

"This is UN Secretary General Brunhild Manahan speaking. State your identity."
"UN Military Grand Marshal Iseya Sugaku, sir. I believe that this rank promotion I recently got is related to what I would request from the UN."
"So you accepted our call… That is fortunate indeed. And yes, it does relate to what your request will entail, Grand Marshal. Rest assured, the UN accepts your request of sending full number of specialized agencies divisions to reinforce the military. They deserved it for their service in Trans-Dimensional Warfare. We honestly didn't expect that you'd become part of GUF as well…"
"Family reunion might cause me to drift from the original objective 35 years ago, sir. But here I am, back to home. We have another war at hand, as you already informed."
"Indeed. And again, it's directly related to dimensional threats we keep our eyes on. As High General Maverick Carne said before, our military is in your hand. You got your objectives already, Grand Marshal. Make the best use of the specialized agencies. We have another war to win, this time for the Alliance."
"Roger, sir. WSL will stay until further assistance required. And we won't fail the UN and the Alliance."

Before Iseya could terminate the call, Brunhild interrupts her.

"Oh, and don't forget to give my regards to your brother."
"You can count on me, sir."

As the call fully terminated… "So Brunhild accepts your request before you even asked for it…" There's Yasei, standing just below a tree. Iseya can only grins, because she knew what that means. "It was you right, Onii-chan? And Brunhild-san also sent his regards to you." Yasei chuckles lightly upon hearing that. "You got me. I told Yukari to go to UN Headquarter on Manhattan. About the rest, you know already. At least she's better than some other AU version of her I'd wish never encounter. She can be playful at times, and sometimes it's not funny, but she does know when it's time to get serious."

That makes Iseya giggles in return. "Indeed. And I'd say they'll arrive sooner than later." Her brother nod in agreement. "This won't be easy. We all know what's at stake here. I do, you do, Brunhild does, Yori does, and Tsurubami does as well. Though, Yori wouldn't make her move right away. That much is to be expected. I'll make sure to properly thank Brunhild. As of Tsurubami, they'll join when they're fully ready. You know what they must do as of now, cleaning the remains of Mugenri Civil War."

The two siblings, leading their respective dominions, both of them looked at the sky, wondering what they will do next. Yasei Sugaku, Zen Captain of Gensokyo Union Fighters, and Iseya Sugaku, Grand Marshal of United Nations Military. Both of them eventually came to an agreement.

"UNM will be in the frontline alongside HMF. GUF will provide supports when the unexpected happens. You can count on us, Onii-chan." (Iseya)
"Alright, but just know that UNM isn't alone in this struggle. I'll repeat what Brunhild said. Make the best use of the specialized agencies." (Yasei)

While waiting for the rest of GUF and UN Specialized Agencies divisions, they discussing a topic related to Historia Alliance.

"So, did Saderan Empire managed to recover from the Civil War?" Yasei is the one who said that. That question refers to the latest member of Historia Alliance, though their name is classified for now. "Mostly, and I believe in less than 2 years, the manpower will be replenished." Iseya replies, knowing well what that means. "Alright. We better don't force them to join this war. It will strain our relationship with the current Empress. Let them have their peace, and once they decided to join, we will let them." Both of them nod simultaneously.

And just in time, all of GUF members and UN reinforcements gathers in Gensokyo open field. Another war in another universe, and this time, it might shake the very balance of Multiverse itself...

AN: There's some things that I want to say. Alternate history and Isekai scenarios are just very appealing, at least in my opinion. That's why this chapter is dragged for very long. Especially after I found out that GATE - Jieitai has some very good crossovers. Originally, this chapter doesn't even has any mention to it, but after the last AutoRecovery deleted unexpectedly, I decided to add a reference to it. You could say that I also plan to make a crossover of it myself.

Regarding UNAF Generals, I tweaked their names based on 'List of firearms' in Wikipedia. Really, that's not a joke. And there's one thing that differs Historia UN from our UN. One, Historia UN is constantly threatened by potential dimensional invasions, hence the formation of UN Armed Forces, and later included to UN Military after admission of World Senshado League (Girls und Panzer reference), while our UN mostly deal with internal problems, and you know what I mean. Second, our UN employs peacekeeping forces instead of having military forces. You can see 'United Nations is a Superpower' trope for more detail. Lastly, It's unknown if our UN managed to stay for a century, but in Historia Universe, it does.

And mind you, although UN Military bear some similarity to GDI from C&C Tiberium series, it didn't go the same path the latter did. Why? Trans-Dimensional Warfare. Ten year of struggle to defend the Earth from dimensional invaders strengthen the bond between UNAF soldiers, showing the world that they can be united under one banner. So, while UN is still in charge of internal problems, the military are given free reign to investigate anything related to dimensions, and in return, they are expected to report it to UN Security Council. Naturally, the military will have a say in the meeting related to dimensional threats, due to their service as stated above.

Let's just say I choose a name that pops in my mind for UN Secretary General in this saga, as in, Clash of Gensokyos.

And you read it right, here, UN Specialized Agencies also has military divisions to make sure that they can help UN Military in combat beside that of their assigned roles. Apparently, Blitzkrieg Lotus threat is so high that UN Secretary General allows this right from the start. The only similar situation happens back then during Trans-Dimensional Warfare.

How about GUF treaties, you say? I made it to show what GUF has to go through before becoming one of Historia Universe major powers. While their wars aren't lethal, it does change Gensokyo massively. How so? Initially, Historia Gensokyo isolating itself due to fear of legends extinction. Now? GUF is the leader of Historia Alliance, as stated by Tsurubami in the Prologue. And they also actively trying to made contact with other universes, as shown by successful attempt in making alliance with HMF. In fact, these points is the main driving plot of this saga as a whole!

Last word, you read it right, again. The WaHH plot here is changed, since I combine both Vaati Star's Fugere Illusion timeline up until Book 2 and Savato93's The Outsider timeline in this story. Reimu is replaced by Yasei, who was still human back then, since Reimu became an oni shortly after Eternal Night Incident, while Yasei arrives days before Perfect Possession Incident take place. And somehow, Heavenly Jade Scepter Incident happens before it, thus marks multiple Butterfly Effects that eventually culminates in formation of GUF.

I'm running out of words, so that's all I have to say. Comments, reviews, and critics are always welcomed. See you in MSS perspective of Chapter 1.
