Angrboda

...Under Londinium, huh?

I knew there was a subway underground, but who'd have thought there'd be something "under" that.

And how dense this Demonic Fog is... Isn't it getting thicker the lower we go?

I'm not sure. I can't observe from here, but if it's getting dense enough to visually confirm...

Then maybe what Babbage said was true. After all, there really was a path leading below.

？！

London has had an underground transportation network since the middle of the 19th century.

But there are no records of underground passages like this. ...Perhaps the remnant of a national top secret project?

The Mage's Association only excavated the area right under the British Museum...

Hard to think an individual secretly built an underground labyrinth, so maybe this existed before London took shape?

There's this old story. Deep underneath the Tower of London

The head of an ancient king of Britain named Bran is buried, and it watches over Londinium.

A head, huh...

Interesting story, huh? The Tower of London has other stories, like the crows.

Oh, I know a bit about that one. They watch over London

They're said to be the avatar of my father, King Arthur. I mean they're crows! His avatars are crows! Ha ha!

What? I think crows are really cool. Raven Master is really cool, right Mash?

Uhh... What do you think, Senpai?

...

Right. I think so too, Senpai.

That's...true. No, I, well...

？！

Setting crows aside, you can't track this underground passageway or routes from your end?

Sorry, just as Mash mentioned earlier, there are no records. You'll have to explore on your own.

Hopefully it's not too complicated... But it already sounds like a labyrinth.

Deep underneath London... An unknown underground passage, underground labyrinth.

If what Mr. Babbage said was correct, then a "large-scaled machine" should exist.

？！

Yes, the source of the Demonic Fog filling London. The Massive Steam Engine Angrboda, powered by a Holy Grail.

That's what he mentioned right before vanishing. To think a Holy Grail would be integrated into a machine...

But, that makes some sense. The existence of a fog abnormally full of magical energy, and its proliferation.

A strange situation that throws off a Servant's detection ability, and prevents various observations from Chaldea.

I see, by using the power of the Holy Grail, something like that would be possible.

That may also explain the mechanism that materializes Servants from the Demonic Fog.

By incorporating the Holy Grail into a device, the Demonic Fog gained the ability to summon Heroic Spirits.

Such speculation is also possible.

But Angrboda, huh? That's a grand old name.

？！

Right, Angrboda is a Divinity from Norse mythology. They brought forth Fenrir, World Serpent, and the Goddess of Death among others.

With Loki, right? An unbelievable woman giant, but I don't hate her.

It's not often that you see someone give birth to so many troublesome beings

Definitely worth punching. I'm sure she has thick skin too, so I can get down and hack her into pieces, right?

(Oh, that's what you meant by "don't hate her"...)

(It's been so hard to retort to all this... I'm sure Mordred is saying everything on purpose)

(Y-Yes. I believe Mordred's mother was...)

(Yeah. A witch among witches. None other than Morgan!)

Looks like they're finally here. Hostiles.

Beat me to it again. Detecting multiple targets! Looks like there aren't any more Helter Skelters.

Quality aside, they're coming in large quantities! Be careful!

Roger that. Master, starting combat!

...We've come pretty far down. This is the second level, isn't it?

We've travelled pretty far. We're most likely under Hyde Park now.

Oh brother. We've walked quite a bit...

I'm mapping the whole thing here. You shouldn't be traveling in circles, at least.

Taking into account Fujimaru's stamina, you should probably take appropriate periods of rest.

Doesn't look like we'll get that chance. They're here again.

We've got enemy signatures. Quite a few! It will be another series of battles. Be careful!

Roger that. Master, give me you orders!

...What level are we on now?

The fourth level. We went down a set of stairs earlier.

We're currently several hundred meters underground.

We've gone pretty deep. Isn't it going to be a pain to go back up?

...More hostiles again. It really is quantity over quality.

Master, give me your orders. Going to demolish the enemy group!

What the hell is this?

...Almost identical to the Fuyuki Greater Grail. Incredible magical energy.

So much magical energy, I can feel it strongly even in the Demonic Fog. Such a giant Magical Reactor Core...

I can observe it here, too. This is amazing. No doubt about it, "that's" what's creating the Fog.

I've never seen a machine this big. Angrboda... The name of a giant fits perfectly.

I'd love to take a closer look But it looks like the last boss is here.

Oddly enough.

Oddly enough, it is just as Paracelsus said. Evil must be stopped by those who do good.

The Massive Steam Engine, Angrboda. This is our evil embodied, but it is also our hope.

Your path ends here. Good will now be destroyed by our evil.

You folks really like to talk. Shut up. What ends here is your life.

Heroic Spirit Mordred. The 13th Knight of the Round Table and legendary Treacherous King.

I thought you'd stand with us, but it seems you're now a hero of good. Ironic.

？！

I am Makiri Zolgen. The first leader of this "Project Demonic Fog."

One mage seeking the annihilation of this erathe Fourth Singularity, by releasing Demonic Fog all over England.

All of England!? So it's not just London! That's...I have to say, going to be tough...

Destroying London alone isn't enough. Only by destroying this era completely can I erase the Foundation of Humanity.

That is our King's wish, and an act which we had no choice but to embrace after our surrender.

Our King... Master, is he part of the same group as Lev Lainur?

？！

There's no need to say another word. Angrboda is shifting to overload mode.

A powerful Heroic Spirit, one sufficient to truly awaken the Demonic Fog that fills the city, will now materialize.

A single strike from him shall activate the Demonic Fog, engulfing the world. "Everything" will meet its end.

Now, behold. The Heroic Spirit we desire shall appear from the Demonic Fog shortly.

A Pioneer of the Star, fitting for the end of the Myth of Humanity. Or perhaps, this planet's glimmer

I ain't letting that happen. I'll kill you, and destroy Angrboda.

I'll never forgive someone other than myself for trampling over Britain. Even if you are a human.

!?!?!? He's not...a Servant!?

Just a hunch. I told you they're usually right, remember? He's human.

I don't know if he's rightfully from this era, or "shifted" like Babbage was.

Why are you doing this, Makiri Zolgen? Why are you destroying the era you live in

Of course, I tried to resist. But I realized everything was useless.

Even if I wished for the salvation of all humanity, the world where they should live has already been incinerated.

Past, present, and future. Our King has decided not to allow them to exist.

All will be destroyed before it is achieved.

The King has proclaimed to us that he tires of seeing more of this ugliness and existence.

Then, before long...

No, there's nothing left to say. With the power of our King I shall destroy you.

You will die here, without seeing the last Heroic Spirit. Come forth from the sky of destruction, our Demon God!

What!? This presence, this mass magical energy!

He's summoning a Demon God! Just like the last two!

One of the 72 Demon Gods. Demon God BarbatosThis is the form of our evil.

My King has "found" my evilness. The ugliness lurking within me as I desire human salvation.

With the epitome of my abomination Begone, you who seek to spread good as I once did!

Demon God Barbatos has gone completely silent. We've won.

？！

Right, Senpai.

That was a weird monster. That was hard even for me to fight.

Now all that's left is to smash this big thing. Let's do it, Mash, Fujimaru.

...It's too late. There's enough Demonic Fog...filling London...already...

You're still alive? You're tough.

Now... Come, my last Heroic Spirit...

Pioneer of the Stars... who can complete my evil!

...Thou who are trapped in a cage of madness... and I the summoner who holds thy chains

Seventh Heaven clad in the great words of power! Come forth from the circle of binding, guardian of scales!

This is... A Heroic Servant summoning incantation!?

Shut your mouth!

...Shut up and die.

Doctor, his last words were a Heroic Servant summoning incantation. With...the phrase causing Madness Enhancement.

Unfortunately, you're right. Mash, Fujimaru, incoming Servant!

He didn't use the full spell, but the Demonic Fog served as the circle and the rest of the incantation.

I can see the Servant response clearly from here. Mash should feel it too. This is...

A Great Hero-class magical energy response. No

See? I sacrificed my life for this summoning, and it succeeded...

You're still alive!? You're human, right? How can you be so tough

Magical energy of the Holy Grail, amplified by Angrboda... The power of the Demonic fog...all concentrated onto "him"...

...He has reached the realm of the gods!

The magical energy response is huge! It's coming!
