Author's Notes:

Hey everyone! Do you guys enjoy the latest chapter of the Camelot Singularity. I had to work so hard to write that chapter. Which involves watching the movie itself. Now then, let's go back to the Septem Singularity where the heroes are now continuing their battle against the United Empire.

But as they successfully rescued Boudica, Nero had an unexpected encounter with none other than Romulus the founder of Rome. With Nero being disturbed, this causes the others to be really worried. However, Sougo and Ritsuka did some cheer up for Nero. Which then causes to calm down.

Quartzer Final

Quod Flagellum Dei

3rd POV

In the United Empire Palace, Gaul

60 AD

As the heroes continue to run, Nero asks Jing Ke, "Are you sure this is the way, Jing Ke?" The latter sighed as she turns her head towards Nero and replied.

"This is the second time I've gone to the emperor. Don't worry, I promise I'll guide you to the throne without fail."

"Ok then Jing ke-san, sorry about that." Kiva said.

Nero looks around the palace and marveled at it," The city sure looks familiar... It's impressive, they even replicated the palace down to the interiors. When did they build it? ls this some sort of spell?"

"That's possible. It might have been the power of the Holy Grail."

"Look Doc, we saw many crazy things in our lives. But that's so far off…" Sento muttered.

"Okay guys stop arguing! Look!" Geiz pointed at the enemy.

"There's no time to chit chat. The enemy's noticed us—They're not human." Jing Ke shouted.

"Nor are they Servants. They're probably monsters created by Magecraft." Romani exclaimed.

"Really? You serious now!?" Den-O shouted back.

Nero gave a disgusted look, "Ugh, monsters huh? Whatever they may be, I am no longer afraid!"

"If that is what it is then, Emperor of Roses let us see what your resolve gets you." Artoria Alter and Jeanne Alter shouted.

"Master, Tokiwa-san, everyone! It's enemy lifeforms... Commencing battle." Mash shouted.

Sougo POV

Inside the Palace of the United Empire, Gaul

60 A.D

As they started to fight the monsters, the battle was very clearly one sided. With most of the monsters being destroyed mostly by the efforts of the Kamen Riders and the Heroic Spirits. As they finished the fight… They heard footsteps and saw Romulus smiling at them, "...Here you are, my beloved child."

Nero's face then devolved into a serious look as she replied, "Umu, I am here! O proud founder of our great nation, King Romulus!"

"Yes… And this time we will be putting an end to you!" Dark Kiva declared.

"...Splendid radiance. In that case, should I call out your name, "Emperor?'" Romulus asks Nero.

"Oh, there's no need. Call me what you did just now— Whether it's the past, the present, or the future. I am the one and only Fifth Emperor of the Roman Empire! Holy Progenitor, O King Romulus! I hereby challenge you with my warriors, my swords!"

"Hey! Hey! Nero-san… You're not going to fight him alone!" Kiva shouted as he and Dark Kiva go towards her.

"My… Wataru, Taiga. Are you sure do you want to join?" Nero asked.

"Of course, after all… We promised that we will fight together, right?"

"Wataru's right… You can't do this alone." Dark Kiva agreed.

"Interesting friends you have there, just who are you two?" Romulus asked.

Kiva looked at Decade as the latter smiled, "Just some Passing through Kamen Riders remember that! Your Majesty!" Kiva shouted copying Decade catchphrase. He then pulls out a Fluestle and called out, "TATSULOT!" He then puts it on Kivat's mouth as he blew it. As this was going on a golden metal bat and Sword appeared with the sword being grabbed by Kiva. Surprising Ritsuka and the Chaldea crew.

"Pyun! Pyun! Tension Fortissimo! Hey Wataru! King! Jiro! Ramon! Riki! Long time no see!"

"Umm…. Who is that?" Mash asked.

"Tatsulot, another of Kiva's companions." Decade answered.

Tatsulot then breaks Kiva's shoulder pad chains as it turns then pads into armor that emits golden bats. He then inserts himself to Kiva's left hand as he shouted, "HENSHIN!" Kiva's armor then turns gold and red with his visors turning red as the latter swipes his hand and creates a red cape with flames coming out.

The Chaldea crew marveled at this with Ritsuka, the Artoria trio, Romulus and Nero asking, "What is this form?"

"Everyone meet Kamen Rider Kiva Emperor Form!" Jiro announced.

Nero then muttered, "Emperor…." She then smiled, "Well then Wataru, Taiga as a fellow Ruler. I'll allow you to join me."

Romulus also smiled, "And as the progenitor I'll allow it, Nero Claudius, Wataru Kurenai and Taiga Nobori. Show me you can trample over Rome's love with your love." He then grabs his Spear, "Behold. My spear-—"Rome" is here!"

"An enemy Servant is approaching. Speculated class is Lancer. Battle commencing. Master, your orders!"

"Well then… help Wataru-san, Taiga-san and Nero handle Romulus. Mash, Everyone! We will take care of the minions!" Ritsuka commanded.

"Well then… It's time for me to call the others!" Den-O then called the Den-Liner, from which the other Taros and Sieg emerged.

"Geez… Sempai looks like you are in a tough spot!"

"Well Momonoji… It's time for us to share the spotlight…"

"Yeah, it's been a long time, Momotaros."

"Guess I'm also honored."

"Yeah, yeah sure here." Den-O SF then give out the belts as the other Taros put them on and scan the passes.

"HENSHIN!"

ROD FORM!

GUN FORM!

AXE FORM!

WING FORM!

They then turn into their Rider Forms, with Kintaros' Rider Form having yellow armor and a horn on his helmets forehead.

"Would you mind if I string you along?"

"Mind if I defeat you? Can't hear your answer!"

"My strength will make you cry!"

"Advent! To the top!"

Mash marveled at this, "Wow! Well then let's go!"

The others nodded as they started to fight the mooks, meanwhile Kiva Emperor, Dark Kiva, Mash and Nero started to clash with Romulus. With the latter proving to be a match to the three. As his skills with the spear is unmatched, with it giving him the power to manipulate plants and trees. Nero tried to use her flames to burn the trees. But Romulus used his branches to keep her restrained.

"It's going to take more than that to take me down, Nero!"

"What are we going to do now?" Mash asked.

Nero smirked, "Hah! Do you really believe I attacked you just to kill you myself?" Romulus widen his eyes as he turn and saw Kiva slash his back with the Zanvat Sword and Dark Kiva piercing him with the Jacorder. Causing him to release Nero. Who then started to cough and gasping for air.

"Are you okay? Nero-san?" Kiva asked as he checks on her.

"You seem to almost suffocated."

"Yes, I'm fine. But we have to help your brother." She then pointed at Dark Kiva was now about to be overwhelmed due to the trees. They then slice the branches that are approaching Dark Kiva.

"Are you okay, Nii-san?" Kiva asks Dark Kiva.

"I'm okay… But jeez your first king is such a powerful son of a bitch." Dark Kiva muttered.

Romulus smiled, "What's the matter?! I that all you got!?"

Nero then got up as she smirked, "Of course not… Come on Wataru, Mash, Taiga let's go!"

The two nodded as they and Nero resumed fighting Romulus who then smiled as he declared, "Well then have at you!" As the latter unleashed more trees. Nero, Kiva Emperor, Mash, and Dark Kiva then suddenly destroy all of them with Dark Kiva creating a large crest from which it hit Romulus in the back. It then launches him towards the four who then proceeds to slash as well as continuously punching and kicking him in the chest.

As Romulus started to stagger, Dark Kiva then shouted as he uses his Jacorder to pierce Romulus in the chest as he creates a crest in the top and jump through it causing Romulus to be on a hanging position, "NOW WATARU! MASH! NERO!"

"Yes, Nii-san! You ready Nero-san, Mash-san?"

Nero smiled, "Ready as I'll ever be, Wataru."

"I am ready too, Wataru-san!"

Kiva Emperor pull out the Fluestle from the sword and put on Kivat's mouth.

WAKE UP!

The sword then glowed red as Nero nodded and pulled out a Rose as she chanted, "See my talent! Hear the thundering applause! Thus, praise! Golden Theater!" As she does this the whole background turns into a theater and rose petal started flying and her sword flares up. The two Kivas as well as Mash marveled at what they saw.

"So this is the theater that you so happily talked about…" Kiva muttered, he then slide the hilt of the sword up and down again as it whistle. It in turn causes it's blade to turn red. They then started to charge as Nero shouted.

LAUS ST. CLAUDIUS! (ラウス・セント・クラウディウス (童女謳う華の帝政)

As they charged Romulus tried to defend by desperately trying to create more trees only for him to get slashed by the three. With Dark Kiva touching down the Jacorder string. Causing him to wince in pain and fall down.

The others then noticed this as Romulus was now coughing blood, he looks at the three and smiled, "...Your love, is so dazzling, Nero. My eternal crimson and gold empire. I entrust it all to you and your heirs. Don't forget. Rome is eternal. Therefore, the world must always be eternal. Remember that..." He then disappeared in a bright light.

"Looks like it's over." Kiva said.

"We've defeated the enemy Servant, Lancer Romulus. Victory is ours." Mash proclaimed.

"We won? In that case... ...Umu. Rome shall be restored to its former glory." Nero shouted.

"That's true, more, or less, but we still haven't found that Court Mage. We've got to search for the Holy Grail."

"I agree that Lev bastard is still out there!" Sento said.

"Hmm? But the United Empire has already met its end. Isn't that right, Unseen Mage?" Nero asked.

"That's certainly true, give or take. But unless we secure the Holy Grail, our purpose will be—"

Suddenly Jing Ke interjected, "Wait, someone's there. Though it's not a Servant." They turn to where Jing Ke is pointing, and it was none other than Lev Lainur who was now walking towards them.

"Oh look at here… It's pointy nose hat Bastard." Den-O SF muttered.

Lev then clapped sarcastically while grinning, "...Well, well. To think you took out Romulus. Nice work for a "mere" Demi-Servant and two so-called Kamen Riders. Have you become more powerful since I last saw you at Fuyuki? However, a Servant is still a Servant. Sorry, but you'll never surpass the power of the Holy Grail." He then pulled out a golden cup. Surprising the heroes.

"ls that the Court Mage? Then that golden chalice he has is—" Nero said while widen her eyes.

"Your guess is correct." Decade interjected.

"Yes, that's the Holy Grail. It looks similar in shape to the one we saw before..." Mash exclaimed.

"Who could've thought a Court Mage would ignore his king's crisis. I guess betrayal is second nature to you now, Professor Lev? Actually, perhaps this is the real you? You seem more energetic than when you were at Chaldea." Roman snarked.

"Romani… We get it, okay. You're angry. Let's just focus ok." Olga said.

"Hey! Let's just save the small talk, guys!" Ritsuka interjected.

Ritsuka's right! Okay Lev hand over the Holy Grail!" Zi-O shouted.

Lev sneered at the two as he rants, "I see. Looks like you've learned to talk back, boy." He then focused on Zi-O, "And you and your masked friends are really starting to get on my nerves…. I hear you two did quite a bit in France. Thanks to that— I really got yelled at! I would've been back at the Temple already, but I got sent back out! As a result, I am here to do some clean-up. My plan was to give the Grail to a fitting fool, then enjoy what would unfold. But you ruined that."

"So that was your plan, huh?" Geiz said.

"...I see. Find a human, or a Heroic Spirit who wants to plunge an era into madness. Then if you give them the Grail, that era would surely
drive itself into madness.
That's what happened in France, but this time—"

"Yes, the Holy Progenitor Romulus did not wish for the downfall of mankind. That's why—"

"You have no other choice but to interfere, yourself. That's quite ironic, Professor Lev. In this era, the only betrayer of mankind is you."

"You must be so proud of yourself huh? Long nosed bastard." Den-O SF snarked.

That last comment causes Lev to grit his teeth, "Shut it, trash. I never had any hope for humans in the first place. You either, Ritsuka Fujimaru! Sougo Tokiwa! You two think you can stop me, Lev Lainur, just because you defeated a few Servants?"

"It's not going to like it did before!"

"It's true, you've changed. You've grown quite a bit. You've grown more stupid, that is! Don't you know that if you try to resist, you're going to suffer that much more?"

"Is that all you have to say?" Decade interjected.

"What did you just say?"

"I said… Is that all you have to say? Jeez your still as narcissistic and ill-tempered as ever. I'll say this so that you can understand, nobody cares about your opinion, okay? Nobody! So… What are you after, anyway?"

"Why you…. I believe I told you, I already long completed my objective. This is what you should be asking, Ritsuka Fujimaru! Sougo Tokiwa! "Why did you destroy humanity?" Although, even if you did ask me, I have no reason to answer you. Besides, I think you people misunderstand something. Recover the Grail, repair the Singularity, protect mankind— Protect humanity? —Idiots. There's nothing you can do. There's no point in struggling. The end is certain. You're insignificant, worthless! You will perish in sorrow! Allow me to show you the favor of our King!" As he said that, he suddenly transforms into what appears to be a pillar with red eyes.

"Fou! Fooou!"

"What the fuck is that!" Den-O SF exclaimed.

"What's that creature! It's ugly! You're uglier than anything of this world!"

"Did he just turn into a pillar?" Zero One asked.

Lev then shouted, "Haha! Hahahaha! That's right! That ugliness will be your undoing!"

"...This signature, this amount of magical energy... ...This signature, this amount of magical energy... That's not a Servant, not even a Phantasmal Could that be—could that be an actual "Demon" from legends?"

"WHAT!" Everyone shouted.

"Allow me to introduce myself again. I am Lev Lainur "Flauros!" That name causes Ghost, Wizard and Zi-O to be shocked.

"Wait? Flauros? You don't mean…"

"One of the Seventy-Two Demon Gods! The Demon God Flauros— This is the true favor of our King!" Lev shouted.

"How disgusting... You are the reincarnation of evil!" Nero exclaimed.

"A giant pillar of flesh protruding out of the ground? A large amount of magical energy... Doctor!"

"And wait… did you just say Seventy-two Demon Gods as in the Seventy-two Demons of Ars Goetia?"

"You're right, Souma-kun…...Flauros. He did say Seventy-Two Demon Gods. In that case, the King he speaks of is— No, there's still not enough information. That's impossible, Demon Gods do not exist!"

"Um… Hello Doc you see reincarnated heroes all the time and you're shock that there are demons?" Diend said.

"...Fou! Kyu, kyu, kyu, kya!" Fou said.

"We don't know the details, but that thing is dangerous. Here it comes! We've got to take it out!"

"Ok Doc!" The heroes then started to fight Lev who was now trying to zap them with laser beams. Only for the heroes to counter every attempt to zap them. With their arsenals, as Lev staggers Grand Zi-O, Kiva Emperor, Mash, and Nero then used their signature attacks to defeat Lev. Who then transforms back into his human form.

"...lmpossible... A mere Heroic Spirit... and a Masked Man. Do you really think you can repel one of the "Gods?" No, this is simple miscalculation. That's right, that must be it. It's been too long since I left the Temple. My cells are starting to die off. But I am entrusted with the mission to incinerate the future. It's not as if I didn't have a contingency plan."

The Heroes felt that there's something off in the air as Mash said, "Is something else coming?"

"Watch out! I'm detecting the Holy Grail's activation! Mash, Fujimaru-kun and Tokiwa-kun, something's about to happen!" Roman shouted.

"...By sacrificing ancient Rome, I have managed to summon the strongest hero. Rejoice, Emperor Nero Claudius. This one is truly fit to bring the demise of Rome."

"Rome is the world, and the world shall never come to an end!"

"Yes, and you can bet on that!" Kiva agreed.

"Even pride is nothing more than ultimate stupidity if misdirected, huh? See with your own eyes, the end of your world! We'll pull the bottom out on humanity! We'll destroy one of its seven foundations! —By the esteemed words of our King! Come forth! The great hero of destruction, Altera!" Lev then summoned a girl with brown skin, white hair, brown eyes and is holding a rainbow sword. However, as he then laughs as he continued, "Kill. Destroy. Incinerate. With your power, burn Rome and this Singularity to the ground! Hahaha! It's over, Romani Archaman! Your dream of continuing Humanity is nothing but a dream! This Servant is the ultimate destroyer' Altera is a Heroic Spirit, but her power—"

"—Silence."

he froze as he was sawed in half by the girl Altera, which shocked everybody, "Huh?"

"Did she just…"

"Fou!"

"What? Lev Lainur's signature has disappeared!"

Den-O replied, "Yeah we saw that bastard get cut in half."

"I agree… He...He was cut in half by the Servant he summoned! Her True Name is Altera. She's probably a Saber." They then saw Altera grab and absorb the Grail.

"Woah this is not good." Ghost muttered.

"Altera has the Grail! It's being absorbed...huh? She's absorbing it..."

"I am— A warrior of the Hun. And it's King. I am the King of Destruction, the one who destroyed the western world. Destruction—" Altera muttered.

"Hun... as in Attila the Hun?"

"I think I have the feeling that we should get out of here." Artoria Lily said.

"I've got a bad...feeling about this! Mash, something's going to happen. Even I can tell!"

"Huge spike in her magical energy signature! This must be her Noble Phantasm—an Anti-Fortress level at that!"

"Master!"

Ritsuka then commanded, "Deploy your Noble Phantasm, hurry!"

"Right!"

"This is what you people said. That I am the divine punishment itself. —The Scourge of God."

"Let me help you, Mash!" Wizard exclaimed.

DEFEND PLEASE!

They then deploy shields that protected them from the blast.

A few minutes Later

60 AD

"...I thought I was going to die." Nero said as she and the others got up. With most of them dusting off the sand. With Boudica greeting them with a smile.

"Thank you, Mash. You too, Boudica. That was great timing."

"...To be honest, that was too close. I ran in to raid the palace from the entrance, only to sense this vast amount of magical energy, so I rushed to release my Noble Phantasm's True Name as well."

"I couldn't have blocked that with my Noble Phantasm alone. Thank you, Boudica."

"Yeah, we owe you one."

"Likewise. But what are we going to do now. Lu Bu and Spartacus were rampaging around the palace entrance and unfortunately got hit by that light. We can't count on them anymore. We've gotten this far..."

"Altera was the name, right? She—" Nero said.

"Already started her advance from the United Empire's capital. Judging from the direction, she's heading for Rome."

"Hey! Hey! That means…" Sento said in horror.

"In that case, is she planning to burn my capital to ash?"

"I'd imagine so. Plus, she has that ability. Even if you're left alive, with the capital destroyed, Rome will disappear as well. Or she might come to kill you after she destroys the capital."

This caused Nero to shouted back, "Either option is rejected. I have no intention of allowing Rome or myself to fall."

"Then we have to defeat Altera. But can we...even stand up to her? Her magical energy is tremendous. It reminded me of the sacred sword in Fuyuki..." That statement shocked the Artoria trio, "And we had a powerful Caster helping us back then. Now..."

"Hey, don't tell me that you're afraid?" Sayo asked.

"You can't do it, Mash?" Nero asks Mash about the predicament, "I would like to think otherwise. Fujimaru, Tokiwa and Mash have saved me multiple times. You were talking about gods and the like, I'm certain the gods and fate are on our side. That's why, Fujimaru and the rest of you
came here. My wish shall see its fruition. Rome will be saved. My people and my Rome will be left for future generations. I'm sure of it. The Holy Progenitor said so as well. I heard it. The world must be eternal. Rome must continue on eternally. Even if its name will someday be forgotten, the many seeds Rome planted will continue on in different forms. The eternal empire will continue to exist. Even if its emperor, state, and name changes. It is the innate truth that mankind will continue to thrive. The tree of life that is humanity. Fujimaru, Tokiwa, Wataru and Taiga I am sure that is the "Humanity" you are trying to protect."

Boudica in the meantime is now confused, "...Emperor Nero. I don't understand what you're trying to say."

"I see. Honestly, I don't, either."

"Well to us that was one inspiring speech." Geiz smiled.

"I understood it a little. At least, I think I did. Even if something clear and defined fades, as long as the world exists, its memories will remain." Mash agreed.

"Fou!"

"How about thinking more romantically? Nero's words gave me strength. She's confident that we can fight Altera. That's why the world won't end. Sounds good to me. Although there's no real basis for it— But it makes you feel like we should at least try. Fujimaru-kun, Tokiwa-kun, Kurenai-kun, what do you think?"

"Jeez… Do you have a fetish for ancient ghost girls, Doc?" Hana asked.

"Well, Let's put out faith in Nero then…" Zi-O and Ritsuka smiled.

"...Got it. Then I will put my faith in your words, Senpai. Tokiwa-san."

"I'll join in, too. I'm tired of things getting destroyed. I hate that one called Altera far more than Emperor Nero."

Jing Ke suddenly appears shocking the others, "I don't really get what's going on, but I think it's safe to believe in Nero Claudius's luck."

"Oh, hey there Jing Ke, where did you disappear off to?" Nero asked.

"I was observing—Altera. It looks like she's slowly advancing. We can catch up if we leave now. That is, if you all want to."

"We just came to a conclusion on that. Nice timing, there. Well then, everyone, time to head out! Let's get the Grail back and save the world! ...At least that was the plan until a second ago. I am picking up a major magical energy signature."

What? What is coming, Doc?"

"It must've been drawn to the power of the Grail when it connected with Altera—Phantasmals, it's the wyverns!"

This caused the others to facepalm and look at Jeanne Alter who was now confused.

"Wyvern? What's that? A monster out of a fairy tale?" Nero asked.

"No, it's a dangerous enemy! Master, your orders please!"

"Gosh… Okay Mash, let's fight!"

As they finished off the Wyverns, they saw Altera walking with more Wyverns following, "Now I'm picking up multiple magical energy signatures. ls, she attracting monsters just by walking? ls she summoning them? I don't know the details, but they're closing in fast!"

"Wyverns again? I never thought I'd be fighting dragons."

"We're used to it. Lord Nero, Senpai, Tokiwa-san and I as well as the others will take the front!"

"So reliable! Umu, I'm leaving it to you!" Nero smiled.

"Fou!"

As they also finish off the Wyverns Romani shouted, "I really want to say "good work," but more are coming. Several times more than before—"

"Wh-What? Several times? That's pretty wild."

"You said it… Red Roses." Den-O smiled.

"...Guess it can't be helped. We'll take those on, Jing Ke, are you ready?"

"Monsters aren't my specialty. But I should take on non-human enemies for a change." The two then stand their ground with Nero asking.

"W-Wait, Boudica, Jing Ke, what do you mean take them on? You're coming with us." Nero said.

"Yeah, you are all going to die here!"

"Exactly. You go on ahead, already."

"What are you saying—"

They then heard a wyvern roar, "Go! You stupid emperor! Never mind this, go protect what you call your world!"

Dark Kiva then shouted, "Come on, let's go!"

"...Apologies. My worthy rival, Queen of Britannia."

"That's right, everyone. No time to look back, we're close to where Altera is—"

As they confront Altera she asked, "...Are you going to stand in my way?"

"That's why we're here." Ritsuka and Zi-O said.

"Yes, I'll stand in your way. I can't allow you to advance further, no matter what. You said that you would destroy the world. I don't understand. Why would you say that you were going to destroy the world? The world is brimming with beauty. Flowers, songs, gold, love... That's right, above all, this Rome, this world is filled with my love. And you'd destroy it? Don't you find that wasteful, Altera, or whoever you are?"

"I am— A warrior of the Hun. And its King. A King of Destruction, who will bring destruction to the western world."

"She's not listening." Decade said.

"That again? How sad, Altera, but even that sadness seems beautiful to me. I can't just leave you like this. I feel a great pain and contradiction in your life. Perhaps your power exceeds mine, but know that you cannot defeat me in love."

"I know not of love; I know not of beauty." Altera replied as she stares at them.

"Doctor, those words are different from before. It seems like she's not responding automatically."

"It is as if she is confused…" Ghost said.

"This reaction— I see, she's going out of control by becoming one with the Grail! This isn't good, talking is not going to end this. Magical energy signature rising. You have to stop her before she unleashes it again. This is the last battle for Rome— Mash, Fujimaru-kun, Tokiwa-kun, Everyone!"

"Prepare for anti-Servant combat! Master, your orders!"

Zi-O and Ritsuka smiled, "It's obvious, isn't it? Let's stop her now!"

As Altera attacks the heroes, she tried very hard at trying to kill them. but not only are they too many. He was defeated by Nero, Kiva Emperor, Mash, and Zi-O as she tried to stand, she muttered, "...I see. In this world... There are things that cannot be destroyed, even... by my sword. I was called, the Scourge of God... Even my... Sword of Mars...can't... I see... Well, that... Makes me...a little happy..."

She then disappeared as Nero muttered, "Altera is gone. Perhaps fate will arrange for us to battle again one day. But...is it over? Have you obtained that Holy Grail—"

She then saw the Chaldea group glowing while Decade and Den-O as well as New Den-O and Zeronos calling the curtains and trains with Mash smiling, "Yes, we've obtained the Holy Grail. This concludes our mission. Thank you very much, Nero Claudius."

"Mash, your toes are looking faint! Don't tell me you're going to vanish too! Fujimaru, Tokiwa, Wataru, Taiga, Fou... I see you're all going to vanish..."

"Yeah, our mission here is complete." Kiva smiled.

"Farewell, we must go now."

"...I had a feeling. My intuition is pretty sharp, you see. You're going to disappear like Altera, my uncle, and the Holy Progenitor. Boudica, will you, as well? Jing Ke, Lu Bu, Spartacus?" Nero said.

"...Yes. This era will be restored. Your memories of fighting the United Empire will no longer exist."

"That's a sad thing."

"Yes, it is..." Mash sadly agreed.

"I will no longer doubt you. I believe you, but this is a problem. It's unfortunate, I haven't given you any reward. You could have been more than my retainers. Something more— No, no sense in saying it, Fujimaru, you will find yourself heading to Rome. All roads lead to Rome, for Rome is the world. Both the Holy Progenitor and I believe so. So I will not say goodbye. Only thanks. So I will not say goodbye. Only thanks."

The heroes then disappeared, leaving Nero alone who smiled.

Year 2019

The heroes are now talking to Romani and Da Vinci with the former saying, "Welcome back and good job, you guys. You retrieved the Grail. With Ritsuka asking.

"When?"

"Yeah, are you sure is this for the beast, Da Vinci-san?" Takeru asked.

"I'll explain. The Grail is the law that decides how magical energies in a dimension is used. Think of it as a world's rules. It normally doesn't have a form, but Lev crystallized it into one. We can't analyze its workings, but we can seal it away. I fiddled with Mash's shield a little, and created a space for the Grail."

"Woah! You did something like that behind our back?" Akari said.

"My shield can do that?"

"Yes. The best place for a relic is in a relic, I figure. It can only hold one at a time, so I yank it out after each retrieval. Got it?"

"Ahhh!"

"DA VINCI!"

"Ok, Grail's retrieval is confirmed. Try your best to search for the next one!" Da Vinci smiled.

"This is our second Grail and we've also achieved our original goal of finding Lev."

"Yeah, but Lev is…"

"...That's right. Altera killed him, and we never found out what his plans were."

"Yes, that bastard got…"

"...That's right. Altera killed him, and we never found out what his plans were."

"...You mean why he betrayed mankind and tried to...destroy it?"

"That's right. We still don't know anything, but still have five singularities left. Lev spoke of "Gods." In other words, there are other enemies out there just like him. What that means at this point, we don't know. All we can do is to recover the Grails one by one, and restore the Singularities."

"We've got a long way to go."

"I agree, Ritsuka."

"Good answer. I'm counting on you, Fujimaru-kun, Tokiwa-kun. We don't have that much time, but for tonight try and rest well. You walked a long way. You'll want a good massage, I'm sure."

A few minutes later

Year 2019

Mash was silent at all of this, "You kook down, Mash."

"Still thinking about Nero?" Wataru asked.

"...Yes. Our parting with Nero was so sudden. I feel bad about leaving her... Even if it ended up never happening, in that last moment,
she was alone. She defeated the people she respected and said goodbye to her rivals—"

"Do you think Nero is lonely?" Ritsuka asked.

"—No, I don't think so. ...I'm sure that's not right. It was a hard battle, yes. We almost died many times, and I'm still scared of fighting. But—
it was a fun journey. Partially thanks to Nero's glamour, but... It was a lot of fun."

"Well, I'm sure it was fun for Nero too." Sougo smiled.

"...Yes. I'll never forget that sky and land, I'm sure. By the way, Senpai, about what the Doctor said."

"What did Roman say?"

"Yes, you need to take care of yourself. Shall I give you a massage?"

This caused the others to sweatdrop and facepalm with Ritsuka saying, "Umm… I'll pass."

"Come on, please! ...Ahem. I really wanted to try it. Yes, that's all. Um, well... I tried it once before, and they said it really hurt...Oh! T-That shouldn't happen anymore. I practiced after that. In my mind." As Mash mutters, Ritsuka turns the others.

"Guys little help here…"

"Sorry, you're on your own."

Ritsuka grunted as he ran Mash noticed, "Huh? Where are you going? Oh, you want a massage in your room, right? Senpai?" She then went after him with the others chuckling.

"My... She sure is cheerful." Artoria smiled.
