Bottom Black Encore!

So, welcome back to SE.RA.PH, Senpai! Let me guess:

I still want to go wild! My long break hasn't ended just yet!

So, in acknowledgement of that spirit, BB is proud to present...SE.RA.PH's super-secret bonus mode!

There are no more threats to your life, and nobody pulling strings from behind the curtains. You're free to enjoy SE.RA.PH to your heart's content, in peace.

？！

Beats me! I have absolutely no idea!

Okaaay, firstly: I am totally innocent! But, if someone doesn't do something, the world will still get destroyed!

So this time I decided to have you save the world, Senpai, without drawing too much attention to my failings!

？！

Hmph... It seems I've become so softhearted over there that I can't face my own darkness.

Or maybe I should just outright say I've grown weak? Isn't that right, Mooncell BB?

Or should I call you...the FORMER Ruler of the Moon?

(Gasp) That voice... I knew it...!

Yep. I'm going to show you a site from the dark web. Something you'd never do now that you've gone straight.

Ready to inject some lemon squash right into your pupils? Got your vomit bag handy?

Then get ready for a nightmarish show that mixes good and bad kids alike into a dark cocktail...

BB Channel/GO! Now live and on the air!

？！

Hello, Master of Chaldea. Nice job getting rid of Beast III.

Under most circumstances, nobody would have been able to do anything about her. Pulling off a victory even while you're so hopelessly outclassed was impressive!

So, thank you...

Thank you so much for working for my benefit! Everything went exactly as I planned!

Now there's nothing left that can stop me. From now on, I can do whatever I want! Me, BB/GO!

I've taken full control of SE.RA.PH. I no longer belong to the Mooncell or the human race.

As an illegal high-grade AI possessing intelligence far beyond humanity's, I hereby declare war on the human race!

？！

...Are you taking me seriously? I really am a ruthless murder machine, you know!

Oh well, I guess I'll just have to fill in the blanks for you, Senpai, since you're so lacking in imagination.

To be specific, I'm going to make SE.RA.PH settle in these waters while remaining a fully digital zone, then patch it in to the Internet at large.

I'll use your factories to mass-produce Earth-conquering BBB robots and use them to imprison humanity.

Your brains have decent memory capacities, so I'll requisition them as bio-processors.

After that, I'll link everyone's minds up here in this digital zone and have them dedicate the rest of their web-based lives to worshipping me.

That is...the most delightfulahem, despicableidea I've ever heard! I won't stand for it! Senpai, you gotta do something about herer, me!

Go on, defeat me! Do it! I've GOT to be weaker than Kiara!

Huh? Oh no, did I really say that in front of you, Senpai...? I'm so embarrassed...

My voice and my thoughts got a bit muddled up there! How could I be so careless! Teehee♡

The bad me, of course!

I mean, come on! Just look at how she looks down on you even as she acts like a kouhai!

？！

...That's right. I almost forgot. You're the reason I'm not getting the respect I deserve, BB.

I'm the BB that was salvaged from Kiara. And you're a copy of the original that was sent from the moon.

I may have helped you defeat Kiara as your fellow BB, but that all ends now.

I won't let anyone get in my way.

Not even a Master with an exceptional track record.

In fact, Fujimaru, you're a blight on all humanity.

I'm not fond of last-minute comebacks. The whole idea of underdogs winning just makes me want to puke.

So I'm going to do everything in my power to squash you.

From now on, I'll be using the slot machine that the other me set up to keep Kiara in check.

Everything on SE.RA.PH will be your enemy. If you want specifics...

Remember those Servants you lost when you first Rayshifted here, Senpai?

I've captured them and turned them into Sentinels.

You'll have to defeat them if you want to open up the route to the central area, where I am.

...Hehe. The only way to reach me is to raise a hand against your own allies, much as it will pain you.

Then, once you get here, you'll find that I'm an even more powerful boss than Kiara was, and I'll put you through a world...no, a whole universe of hurt.

Let's start with some horrific punishment no one under the age of 18no, 21...actually, let's go with 21.5should ever see or experience.

Then, for the finishing touch, I'll send you hurtling down a demonic abyss of despair!

I said despair! Despair!!! Trust me, I've done my homework!

(Dammit, he's got me there...!) That is none of your concern, Senpai!

Being the big, evil boss is all about making dastardly plans on a shoestring budget!

？！

...Hmph. Your reaction isn't at all what I calculated, but no matter.

I've been biding my time, waiting for just this moment. When it's over, I'll have the last laugh.

And just so we're clear, this is NOT about being sad or lonely or jealous after being left alone for so long.

...This concludes our broadcast from BB/GO, the true last boss of this story.

Oh man, this is terrible... I can't believe there's an AI out there with such an evil-looking face... (Sob)

？！

I suppose I'd better explain.

The Mooncell made an exception when it sent me out to deal with the whole Beast III transformation thing.

To put it the way the Mooncell did: "I'm sorry that one of my void phenomenon is causing you so much trouble. I'm sending in my best AI to deal with it."

However...this is where we ran into another problem.

During the Moon Holy Grail War, Kiara absorbed three AIs when she took on that form:

Meltryllis, Passionlip, and BB.

Having become the god of pleasure, she now paradoxically contained three AIs.

Eventually, she took advantage of that and salvaged them from within herself.

Meltryllis and Passionlip defied Kiara, and, as you know, were severely punished for it.

Meanwhile, that BB redefined herself as BB/GO, and decided to help her.

Or rather, pretended to.

In fact, it was at this time that BB/GO (the BB who split off from Kiara) and I (the BB from the moon) met up in secret and formed a pact.

"Moon BB, I'm going to hide in the bottom of SE.RA.PH and build up my strength in order to defeat Kiara."

Please keep SE.RA.PH running in my place while I do that.

I had experience with this sort of thing, so I agreed to do it.

After all, I'd be able to secretly help humanity out in the meantime too.

Of course, I knew BB/GO planned to use me as bait so that she could take over once Kiara was out of the picture...

Neither of us wanted Kiara to gain more allies.

To prevent that, we secretly agreed to retrieve whichever version of BB remained

after we defeated Beast III!

？！

Well, what else could I do? Besides, this was all to help you win!

I needed Kiara Punishers to create an Anti-Beast III item. I couldn't let BB/GO on Kiara's side get her hands on it.

We agreed to leave each other alone while we cooperated to take down our mutual enemy, Beast III.

O-oh, those...?

I guess you could say they were designed to help keep Kiara's arousal in check? Basically, they were a way to translate interference into numbers.

If you had fought on SE.RA.PH without any hesitation, it would have played right into that saucy nun'sI mean, Kiara's hands.

So to make sure her wish for a recreation of the Temple of Time wasn't granted and that she wouldn't fully emerge, I used everything I could think of to annoy her...

In other words...the KPs were actually Kiara Punishers!

Without them, Kiara would've been satiatedwould've emergedlong ago, and that would've been really bad news for Earth.

？！

Anyway, the very last enemy has finally shown herself! Sorry about that!

THAT BB is well and truly capable of going through with that awful plan she told us about.

So I'm going to have you clear this SE.RA.PH no matter what, Senpai.

After all...

I haven't leveled up my Noble Phantasm even a little bit yet! How am I supposed to help you out like this!?

There are many BB prototypes slumbering around SE.RA.PH that Kiara failed to salvage.

So I'm counting on you to collect them and make me into the best kouhai ever! Okay, Master!?
