Prologue: The Warring Era of Heroic Spirits

An intruder in Chaldea! Again? Where are they from?

They seem to have directly entered from a different phase space. But this response? I wonder what this is.

Doctor, is it an emergency? Oh, Senpai, good morning.

Yes, of course. It's good to be cheerful. I also had a delicious breakfast today.

I think you're acting a little too calm! Greetings are important, but for now, intruder!

Fried eggs, seaweed, and miso soup, with stewed pumpkins for dessert.

Even rationing out what little we have stored, I believe this was a frugal yet complete meal.

Pumpkin, huh. We did harvest a lot, so there is an excess of them.

No wait! Intruder, the intruder!

？！

Oh my, I'll go intercept them right away. Senpai, please do the honors.

The response was from around here...

Mash, behind you!

Wh?

Nobu nobuu!

?!?!?!

Wha?

？！

Nobu nobuu!

What is this thing?

Be careful, Mash. It may look like a joke, but it's displaying high combat capabilities.

Nobbuu!

Master! Look out!

Stop right there!

Nobu!?

W-Who are you?

Nice to meet you. I'm from Shinsen Uh... Let's see... Just call me Sakura Saber.

Sakura... Saber?

Yes. I materialized in this world to pursue that mysterious creature...

Wait, wait, man-slayer! Don't leave me behind!

Sheesh, my normal self could take them out like it was nothing, but this is rather hard on me...

U-Um, the two of you are?

Hmm? Me? I am the Demon King of the Sixth Heaven, Nobu No, Demon, right! I'm Demon Archer!

Demon Archer and Sakura Saber... I see.

If I could interrupt, I figured out where that thing spawned. It's a different phase space that collided with Chaldea.

We have to destroy the source of the problem. Or else, Chaldea will be filled with strange creatures.

I finished calculating the coordinates for the Rayshift. Go in there and get rid of them quick!

Understood! I'll hurry over with Senpai! Um, by the way, what will you two do?

We're hoping to do the same thing you're trying to do. Please let us come along with you.

If that's okay with you? Archer?

All right, all right. Well, it is our problem and I've grown tired of chasing after them...

Very well! The Demon King of the Sixth Heaven, Demon Archer will lend you a hand!

Anyway, once you all Rayshift, I'll lock the system down.

There. Now we can have some peace of mind.

By the way, those two Servants... How did they directly materialize into Chaldea?

Hmm, it looks like we got connected to a strange space by an astronomical probability.

Look at the conditions they're Rayshifting into. What's this? Phenomena Corruption from another phase space?

In any case, it's pretty terrible.

Wow... What's this? A group of strange creatures, and something else? They're not quite Shadow Servants...

...Either way, I believe Fujimaru will be able to do something about it

Now it's time for me to go back to bed.

I'm sleepy because I was sending messages to Magi☆Mari till really late last night.

You kept sending her messages and she just kept yelling at you... Is that some sort of punishment?

It's not a punishment, it's a reward!

Though, I need to take a nap or something to reset my mind and regain my footing...

Foou!

Huh? It's you, Fou. You were left behind? Eh? You had a bad feeling so you didn't want to go?

Foou...

Rayshift complete, but... Where are we?

It seems the Imperial Holy Grail lost control and created a separate dimension within this phase space.

Imperial... Holy Grail? What is that?

We can talk later. They're coming!

The Grailis out of control?

Yes. There was a Holy Grail War in our world, but the Grail was tampered with by some strange technology.

At the end of all that tampering, its power got out of control...

Unfortunately, I got involved in the accident and my subconscious materialized. It's starting tocorrupt reality.

Worst of all, it took away most of my power. Originally I should be OP like a Last Boss, but now I'm like a 0.5 star Servant...

In short, I got nerfed to a level 1 noob.

With my power, I should've been a 5-star character. Why did it end up like this...

I'm sorry our Archer is causing you so much trouble.

？！

So that indescribable creature is the manifestation of Demon Archer's subconscious and power?

Y-Yeah. I don't quite understand it myself, but that seems to be the case.

This has nothing to do with you, I'm sorry that you've gotten involved.

It's basically all Archer's fault, so please complain to her as much as you want.

I-It's only being hidden by hair, yes? See, it's just like Mash over there!

Don't lump me in with that thing!

？！

By the way, I found this during the earlier battle. ...A bowl? Perhaps? And a steel pot?

Looks like the magical energy leaking from the Grail copied what's "valuable" in my mind.

Valuable? A black pot and an old bowl... They don't look like they're that valuable...

Mash, can I have a look at them? Hmm, hmm...

What is this? Such dusty looking vessels are valuable in the Far East?

Rude Westerners! Rikyu will punch you for not understanding value in the simple and subdued!

Well, even if you claim this is valuable... Wait, now that you mention it...

I'm curious! These tea set-like things? My workshop will take them!

You're interested in them?

Just look at this black, unsightly teapot! Quality iron, smooth to the touch...

...But is super dull in shape and color. Still, I feel like it has an indescribable charm, or maybe not so much?

Oh, you are quite knowledgeable. I'll make you some tea later.

Let's see, I'll rent out an entire temple somewhere...

No, no, there is no way a teapot could ever explode.

You think so?

？！

I-In any case, let's head towards the center of this Singularity.

We somewhat forced your hand for assistance, but I hope we can work together well.

Right! Let's go, everyone! On to the journey that will unify this nation by force!
