(Trails into Reverie ost - Now, at the Beginning)

"Well done, everyone." Arceus said as everyone gathered in the conference hall. "I can't thank you all enough. That's all of my Legendary and Mythical Pokemon you've rescued. Words cannot express my gratitude."

"We're just glad they're safe and sound. How are they by the way?" Lloyd asked.

"They're breathing, but Xerneas is helping them nurse back to health. Given time, they will recover their strength."

"I'm just so glad that both legendary and Mythical Pokemon are rescued and good health as everyone else." Elie smiled

"Yeah, thank goodness for that." KeA smiled.

"And now, we can finally begin the meeting. What's the situation in Crossbell now?" Randy asked.

Litchi pressed the remote and then revealed the map of Crossbell.

"We got good news and bad news. The goodness is that the barrier sustaining Crossbell has completely vanished. We can now attack Crossbell if we want too. However, the bad news is that the EDF has already sent out multiple of their soldiers, Zauber Soldots to different areas of defense. Furthermore, we received words from our scouts that Calvard plans to make an attack."

"Already?!" Alisa gasped.

"Then we need to liberate Crossbell quickly before they show up." Machias muttered.

"The only good news is that they won't attack until tomorrow." Robin said. "And speaking of tomorrow, we developed a man to liberate Crossbell."

Litchi presses the button and reveals three teams.

"We will attack from the south, east, and west entrance of Crossbell City all at once. From there, three teams will lead the further assault on Orchis Tower. Rufus's group, Lloyd's group, and Rean's group." Emblem Soren said as Litchi pressed the button again.

"The co-supreme leaders will be stated in Orchis Tower. If we can route them, then Crossbell will be liberated." Musse said. "It won't be easy with so many Zauber Soldots, the Paradox Pokemon and other weapons they have in hand, but with cooperation from other teams, we can overwhelm them with our own."

"We've also analyzed that machine still in the Castle of Mirror. We learn something about a weapon, but we don't know where the weapon is located." Kokonoe said.

"Speaking of that machine. We also brought additional help." Rufus said as Ansem the Wise, Even, Ienzo, Scrooge McDuck, Huey, Dewey, Louie, Webby, Launchpad, Della, Lena, and Mrs. Beakley.

"Oh, Ansem!" Rean gasped. "It's so good to see you again."

"Even Ienzo and Even. How are you guys?" Alisa asked

"We're doing fine, Ms. Reinford. As you can see. We also plan to lend your our assistance." Even said.

"Indeed. Radiant Garden has been save, thank to Rufus and his party. While Radiant Garden hasn't suffer much, we heard what became of Zemuria. And learn about the Singulary: Elysium." Ienzo smiled

"Yes. A super AI is very fascinating. However, the other Rean also pictures my curiosity. I don't know why he set his sights on Radiant Garden to place one of his contraptions and set up a dimension of Hollow Bastion: but we cannot ignore the danger he posses." Ansem said. "Therefore, Rufus suggested we help with that machine in this Castle of Mirror."

"Oh, nice! We got extra help on our side!" Futaba cheered.

"Well, its thanks to yours truly." Lapis said proudly.

"Honestly, it was too much work. We've been through hell tor each the generator!" Nadia groaned. "But on the bright side, we took a tour to Radiant Garden—Our first world we explore otusie of Zemuria~! And it was beautiful!"

"I can't deny that. Kairi's homework is really something. Unlike we've seen before." Swin agreed.

"Hehe. I'm glad that you like it." Kairi smiled.

"Aww, I wish I could see Kairi's world." Estelle giggled.

"Maybe once we have the time." Joshua smiled.

"And of course, we also got other help. Not just Ansem the Wise. But Donald's family." Neve said.

"Aye." Scrooge tip his hat. "Pleasure to meet you all ladies and gents. Name Scrooge McDuck. Donald's uncle. I'm a world traveler you see. And I've heard so much of your homeworld Zemruia and plan to visit it one day. But then this conflict happen. I would gladly like to help out and also start business here in this fine world."

"A pleasure Mr. McDuck." Peach smiled.

"Sup. Names Huey!" Huey waved his hand. "This is Dewey and Louie. We're Uncle Donald Nephew."

"Hey, we're the one who is supposed to name a cool introduction!" Dewey complained.

"Yeah, what's the big idea Huey?" Louie complained.

"Eh, can't win them all." Huey struggled.

"Hiya folks! And whooooa!" The female little duck eye sparkling. "This is absolutely so cool! And so many people!"

"Webby, remember your manners." A Middle-aged female duck.

"haha! Ah, let the kid have her fun. But hey, nice to meet you." Della waved. "I'm Donald sister, Della Duck. I'm also the mother of the triplets who are making a big deal of their introduction."

"Hey! I got a cool introduction I've worked all day!" Louie complained.

"If we can get on with it." Neve said with a cross on his forehead.

The middle-aged female duck cough. "All right, my name is Bentina Beakley. I'm Mr. McDuck's housekeeper and Webby here is my granddaughter."

"Hiya!" Webby wave her arms. "And this is my best friend, Lena!" She pull the teenage female duck.

"Sup." She greeted

"Oh, look Marnie, you got a goth friend you can also hang out with." Bede teased until Marnie elbow his fist. "Oogh!"

"Hilarious Bede." Marnie rolled her eyes.

"Yeah, it's funny coming from someone who looks like a Twink." Lena comment.

"Pffft! Ahahahaha!" Hop and Victor laughed.

"I'm NOT a Twink!" Bede yelled.

"I like her." Marnie smirked.

"What's a Twink?" Lapis asked

"I'll tell you when you're older." Neve respond.

"It means he's young g—" Neve summons his Keyblade and throw it at Ash. "Nugh!" He fell on the floor, causing everyone to sweatdrop.

"Anyway..." Edelgard scratch her cheek. "With the additional help of multiple Professors and men and woman of science, along with Jona and KeA examing that machine, adding Ansem the wise and his two apprentices will bolter our chances."

"Right. In any event, Hoopa along with Palkia will help transport everyone to their respectful point for the liberation." Zhongli said. "We will begin the operation at morning."

"With this many of us, we can definitely liberate Crossbell." Florian smirked.

"Right. With that in mind, we should prepare for tomorrow." Dan Heng nodded. "It's going to be a large scale battle."

"Agreed. Especially the large scale battle we've been through ourselves." Riku sighed.

"Hmm..." Shadow hummed.

"Something wrong, Shadow?" Rogue asked.

"It's about Mephiles."

"Mephiles? What about him?" Mewtwo asked.

"He and Infinite were there along with Phoenix two enemies. We dealt with them, and those guys said their farewells afterward.


Flashback...

"I'm glad that you guys won! But I knew you can do it!" Maya cheered

"Yeah. Listen, how about we somehow help you guys out too. If we got the chance." Phoenix suggest.

"That depends if you have any clients, Phoenix." Edgework said. "But in any event, thank you."


End of Flashback...

"Something that Mephiles said that did bother me. He said timeline."

"Oh, yeah! I remember something." Sonic scratch his hair. "Solaris was erased from existence, right?"

"Wait, he was ERASE from existence?" Sothis asked. "Since when?!"

"Like... well for some time now. Anyway, I don't remember much, but I remember fighting Solaris with Shadow and Silver. Turns out time has reset after he was defeated."

"We didn't remember at the time. However, during our time here in Smash Bros, and the incident involving Eggman using the Time Eater to undo his defeat. We've learn that the event in Soleanna that time was reset when Solaris was erased from time. With it, Mephiles and Iblis. We learn those names when Silver has been doing some digging."

"Yeah. I was wondering why Blaze and some places were familiar to me back with the Wisp incident." Silver struggled. "I've been doing some digging involving time and turns out, what happened in Soleanna this time wasn't attack by Eggman."

"Wait, let me see if I get this straight." Furina pinch her nose. "You're telling me that Mephiles, Solaris and Iblis were Erase from time. But before time was reversed, Eggman never attacked Soleanna?"

"You got it."

"Okay, this is just one thing after another with you guys." Celine muttered.

"Time itself was reset..." Emma rub her chin. "Unbelievable."

"Time is absolute... and there are multiple entities who can control time in your world?" Kevin asked.

"There were a few and Eggman is involved but that's all in the past now." Sonic said.

"I see..." Kevin rub his chin. 'I didn't expect Sonic's world to have that many powerful god-like figures who can meddle with time... but... Zemuria is no longer what it once was now. Plus we have other gods here who can manipulate time. There are many characters who mettled with time... *sigh* Time is absolute by the goddess... and yet everyone is treating this casually. No... perhaps I should remember in this new era now. Not by Aidios alone who can control time. The church had to accept that. Still... should I report this regardless... And even if I do... both the church and I don't have jurisdiction to explore other worlds. And every nation has different gods they worship.'

"In any case... If Mephiles, Iblis, and Solaris were erased from time... then how are they back?" Arios asked

"Perhaps the other Rean must have either brought them from another timeline... or that he summoned them through time and space when he was lost to time." Sothis fold her arms. "Either way, the other Rean's power is another frightening we need to be aware. Who knows what other enemies through spacetime we have to face."

"Yeah. Then let's prepare our final battle. It won't be easy. But we will win this." Rean agreed.

"Right! Let's-a-go, everyone!" Mario declared.

"Yeah!" The Team rallied up.

(BGM ended)


Later...

"All right, follow me, Mr. Mcduck. I'll show you around Toad Town while we have time." Peach smiled as they all leave the room.

"Excellent, miss! By the way, let's talk some business. I've heard about Orbal technology and all, but is there anything else?"

"Oh, I can help!" Alisa ran up with Sharon as they leave.

Zhongli hummed to himself until Rachel approached him. "Lady Rachel. Are you prepared for the battle ahead."

"Naturally. However, I wish to discuss with you and the other involving this other Rean. He's far more dangerous than we expected by summoning other being from time and space."

"Indeed. That's one of the powers of the Chaos Heart..." Zhongli sighed. "I'm I'm sure everyone is aware of his strength and formidable powers."

"Indeed. Do you recall the other topic that I discussed with you and the others?" Rachel asked, causing Zhongli's attention.

"You mean... the "invitation"?

Rachel nodded. "Correct."

Zhongli sighed. "It's certainly a gamble but... Given that "them" also see him as a threat... It would make sense. Everyone said their piece. While there were disagreements... but we're going to need every ally we can get. Should I summon everyone to discuss the final time?"

"Yes."


Later again...

"Are we going with this everyone?" Palutena asked as the Hands, Lumera, Rachel, Es, Mewtwo, Raquel, Sothis, Arceus, Furina, Mavuika, Ei, Miko, Tiki, Venti, Zhongli and Viridi gather in the lounge of Smash Bros.

"Well, given that our goals are align..." Viridi muttered. "Plus, we DID cooperated with them before."

"Then we shall accept nonetheless." Arceus said.

"Valkenhayn." Rachel turn her head as Valkenhayn teleported in.

"Yes, Madame?"

"Sent the invitation."

"At once." Valkenhyn bowed respectfully and teleported away.


Meanwhile...

In the Celestial Globe of Ouroboros... all within was inactivated until Valkenyn rip a hole in the dimension and then he enter the domain.

"So..." Valkenyn look around. "This is Ouroboros headquarters..." He look around. "Ahem. Is there anyone there? I seek an audience with your Grandmaster."

(Trails of Cold Steel IV ost - Ancient Oath)

"Oh my..." A voice spoke as the Grandmaster's pillar lit up with the Celestial Globe turn on and then teleported herself in was the Grandmaster. "This is quite the surprise. I never expected anyone outside of my society would learn of my home."

"Are you perhaps the Grandmaster of Ouroboros?"

"Yes. That is correct. And who might you be, good sir?"

"I am Valkenhayn R. Hellsing. A number servant of Madame Rachel Alucard."

The Grandmaster look surprised. "Valkenhayn of the Six Heroes? And a servant to Rachel Alucard? How interesting. What does a servant of Rachel Aluvard want with me?"

"I came before you to send you an Invitation." Valkenyn answered.

"An invitation?"

"Yes. It involves a matter related to the event in Crossbell. As well as the true enemy."

"The true enemy..." The Grandmaster close her eyes. "I'm aware of the situation of Crossbell... but given the true enemy... you speak of an unknown force... the same force that I've sense entering this world."

"Hmm... As expected. You are one of those who sense that presence when it first arrived a couple of months ago." Valkenyn rub his chin. "The very same. That is why my lady sent an invitation. Will you accept?"

The Grandmaster hummed and given a moment of thought. "Never once, I would receive an invitation. And by Rachel Alucard no less. Given the threat that poses... Very well. I shall accept her invitation. However, I wish to bring a escort. Will that be acceptable?"

"By all means." Valkenhayn replied

"Thank you."

(BGM ended)


Later...

In Alucard Castle of BlazBlue lies the Rose Garden. Waiting by the chair was Rachel Alucard blowing the tea with her two familiars as Nago was the chair and Gil serving tea until a portal appeared and Valkenhayn approached.

"Madame Rachel." Valkenhyn bow respectively. "I have brought Ouroboros Grandmaster as requested. She also brought an escort, will that be acceptable?"

"I'll allow it. Thank you, Valkenhyn." Rachel said as she sipped her tea and then placed her teacup on the table where Valkenhayn stepped away and bowed respectfully and came was the Grandmaster along with a girl with black hair, high pigtails, a white and red kitsune mask at the angle on the top fo her head, along with a sleeveless and backless short red Kimono with crossing black spaghetti straps, Cherry blossom flowers and all that and stared at the Grandmaster. "We finally meet, Grandmaster of Ouroboros."

"Rachel Alucard." The Grandmaster mused. "I'll admit. I'm surprised you would send me an invitation."

"It is not just her." A voice spoke as coming from the portal was Arceus as he flew in.

Mewtwo teleported himself in, A Ray of light appeared as Palutena descended with Lumera and Tiki. Sothis, Es, and Raquel teleported themselves as Zhongli, Ei, Nahida in her adult forms, Furina, Mavuika, and Venti appeared.

A portal appeared and in was Master and Crazy Hand along with Viridi from her Ray of Nature.

"Oh my. I didn't expect that I would also gain an audience with the Goddess Sothis, along with the Goddess of Light, Lady Palutena. Including meeting the Pokemon God himself, and Mewtwo." The Grandmaster said.

"So you're Ouroboros Grandmaster." Mewtwo said. "We meet at last."

(Genshin Impact ost - Devantaka Mountain 11 (night))

Master Hand snapped his finger and a large table appeared with chairs. A portal came in and a couple of Miis in butler uniforms came out, holding in Food and drinks fit for a King as they were set on the tables.

"I thought some of us or you would be hungry so I brought over some food." Master Hand said.

"All right, then let us take seat." Palutena said as everyone then begin to take a seat while The Grandmaster takes hers while her escort stood next to her. "And who is this."

"This is my escort and one of my Enforcers." The Grandmaster said as she turn to her as she nodded.

The girl curtsy.

"A pleasure, everyone. I am Sparkle the I am Enforcer No. 0 of Ouroboros. The Mad Puppeteer. A pleasure."

"No. 0? Isn't that the Fool's number?" Mewtwo asked

"You are correct. However, due to my society's expended, some Numbers are going to be shared." The Grandmaster explained.

"Is that right?"

"And who are these other ones?" Sparkle turn to the Titans, Es, Lumera, Tiki. "I'm familiar with the Creators of Smash Bros because they're a pair of hands. Get it? Because they're just hands? Hehe."

"That isn't the first time someone said that." Master Hand said

"Bwahaha! It gets me every time! I like this one! I can tell she's a mischief type." Crazy Hand laughed.

"You can call me Zhongli. Think of me as... one of the special guests." Zhongli replied.

'So he's the one...' The Grandmaster thought.

"Ei. And the woman next to me is Miko." Ei said.

"A pleasure."

"Hiya! And wow! I never thought the infamous Grandmaster would be such a beauty. Call me Venti." Venti winked.

"Venti, shut up." Furina pinch her bose. "Anyway, I'm Furina."

"Ah. I heard of you. You are Furina Fontaine. A famous actress in Calvard."

"Hehe. A pleasure that someone infamous as you would know me."

"I am Mavuika." Mavuika replied.

"As for me. My name is Tiki." Tiki greeted.

"And I am Lumera." Lumera said.

"Ah. So you are Queen Lumera, adopted Mother to the Divine Dragon Twins." The Grandmaster said intrigued as she placed her hand over her chest and curtsy. "It is a pleasure to make your acquaintance. And on a personal level, I also wish to thank you."

"Thank me?" Lumera asked in confusion. "Whatever for?"

"For summoning the spirits of both Arianrhod and Emblem Leonhardt into your world and turning them into Emblem. They were both members of my society as I cherish all in equal with love and support. Their departure to their world saddens me, even when it is necessary for all of the phases of my plan. I owe you and your children a personal debt of gratitude for allowing me to see them again. Even though it was only Steel and not the Bladelord."

"I see. I am happy that you are comfortable with your formal late member. I hope Emblem Arianrhod hasn't been using for ill."

"Not at all. Noel told me about the agreement to not use the Ring of the Steel Maiden for ill. I have no intention of using her ring for ill. Her Emblem Ring is a gift from you and your children. He would not do anything that would jeoperdize it. And neither would I."

"I see. I am glad to hear that. Although I'm sure your society cause quite the uproar."

"Oh, you don't know the half of it." Sparkle giggled.

"So I'm the last one, huh? Great." Viridi muttered. "Fine. I'm Viridi. Goddess of Nature. So you better remember me."

"Oh, the Goddess of Nature? Oh I heard about you. Rumor has it that you're a children's goddess with a tantrum over humans for ruining nature. And I see some rumors speak truth."

"Okay, WHO is telling me I'm childish!?" Viridi glared. "I swear if it Hades I'm going to throw a reset Bomb on his face!"

"Now, now Sparkle. Be on your behavior." The Grandmaster said with a smile.

"My apologies for speaking my tongue." Sparkle bow with a curtsy.

"I am Es." Es said.

"With the foolish distractions aside, we can now begin business." Rachel fold her arms.

(BGM ended)

"Now then, Grandmaster of Ouroboros. I will admit that I did not expect that you would accept my initiation. Nor reveal your identity. But despite all that, you would reveal your face, exposing your identity. Or is this a mere proxy?"

The Grandmaster shook her head. "It is not. I am the one you invited in person."

"I see. You are more brave than I give you credit for. Very well, we shall now begin why I invited you. The matter involves a certain entity that would jeopardize this world. I assume this also would jeopardize your Orpheus Final Plan."

(Genshin Impact ost - In a Forgotten Tongue)

"The Mastermind behind the event in Crossbell, was it? So... they are the presence that you sense?"

"Correct. However, their identity has yet to be made. But we do know his form and appearance. You are aware of Rean Schwarzer, are you not?"

"Yes. I am aware of Rean Schwarzer. The newly Divine Blade of the Eight Leave One Blade School and Instructor of Thors Class XII and its original members in the Branch Campus of Thors."

"Well, the mastermind behind Crossbell... is someone who took his form."

"His form you say."

"Correct. The only difference is that this "Rean" is malevolent. His presence... and his power is capable of wiping reality. Including Spacetime. Do you know what that means?" Ei asked.

The Grandmaster remains silent as she closes her eyes.

"Judging from your expression. You are aware of his dangerous power." Palutena said

"Yes. I assume you also felt his presence somewhere in early October."

"So you also felt his presence." Mavuika folds her arms. "Correct. He's the one we're looking for. His arrival is that very presence we all felt. We've been investigating for sometimes, but he hid his presence well. There were... incidents that maybe related to what has happened. But we don't know for certain. But what we do know he is someone we all must be extreme caution."

"Everyone including ourselves are gathered to deal with that man. And I assume you also wish to deal with him." Arceus said

"I cannot deny that. His presence alone shook even me when I first sensed him. If what you say is true... then all within the universe is in jeopardy. All existence perhaps will be extinguished." The Grandmaster said.

"You at least understand that."Mewtwo said "We're near the final battle. However, I fear that he won't be killed easily. We don't know how strong he is, all Zhongli did was only small half of his strength."

"Yes. I could never forget it..." Zhongli muttered. "And thus, which is why we share a common enemy. As such, we propose an alliance with Ouroboros."

"..!" Sparkle respond in surprise, even the Grandmaster look surprised

"An Alliance with my society?" The Grandmaster asked. "Even though we may be considered enemies due to my plan involving the world?"

"We cannot deny that." Tiki said. "However, we did learn that all of your plan involving this world and the Sept-Terrions. We do not know what is your plan for the world. But if you threaten this world's safety, then we will step in to stop you."

"We also wish to know who you are. But be that as it may, we know you won't give it willingly. But we will soon once the threat that poses our world been settled." Arceus said.

"Right. Therefore, should the time arrive when that other Rean possesses an even greater threat than before, you won't have a problem joining forces with us, as we did before with Organization XIII." Palutena said.

"I see. Which is why you propose an alliance." The Grandmaster mused. "I understand, therefore I accept."

"You... accept just like that?" Raquel asked

"As you pointed out, this Rean possesses a power that is beyond my comprehension, did you not? Including spacetime. Therefore, it means my Orphaus Final Plan will also be in jeopardy. We do not know what else the power he wields. Therefore, I agree that we should form an alliance. For the safety of both our causes. The world, even the universe itself."

"I see. Then we are an agreement then." Rachel said.

The Grandmaster nodded. "Yes. You have my society's support should the time arise when this dark version of the Divine Blade's plans would threaten this world. Or when we confronted him. Regardless of the situation, I will lend you my support. But I do have conditions that must be met. One of the conditions is my identity remains hidden. All the clues you know is I'm a woman with great power. No one has seen my face. Not yet at least. Only time will tell when I will make my appearance."

"Very well, we can accept that." Ei said.

"The other condition is that until the time we deal with this other Rean, we will keep our alliance hidden until the time is right. I'm sure you also thought of this, haven't you?"

"We also thought of this, yes. But that also means we will remain as enemies. Are you sure you're up for that?" Furina asked.

"Of course. I expect that there will be formidable adversaries. And I would like to keep it that way." The Grandmaster smiled.

"You're an... interesting person." Lumera said.

"Interesting is putting it lightly." Mewtwo muttered.

"Then very well." Rachel got up from her chair. "Then our alliance has been arrange, Grandmaster of Ouroboros. Until we deal with this other Rean permanently, we shall be enemies still until the time has come for this other Rean's final battle."

"Until then, we shall keep this meeting between us as part of the agreement until that other Rean the time to unite our forces." Master Hand said. "Until then, we shall pretend this meeting never happened. We will not take responsibility should we... "accidentally" kill any of your society."

"Bwahaha! So shall we dine in?" Crazy Hand asked. "We don't want to food to get cold."

"Yes. This all look delightful. Shall we?" Tiki asked.

(BGM ended)


Later...

"Ahh." Sparkle spread out her arms as she and the Grandmaster return to the Celestial Globe. "Boy, this is becoming more exciting now!" She turns to the Grandmaster. "Then shall we inform the others, Grandmaster?"

"Yes. I will gather Campanella and the other Anguis to call. Thank you for escorting me, Sparkle."

"It was my pleasure." Spartle curtsy. "I can't wait to rub it on Campanella's face~"


And that's the wrap for this chapter! What an expected twist, right everyone?!
