ACT-6 "United Battlefront"

I see. Observing the past projected on the Earth Environmental Model, and the Rayshift technology that implemented the Heroic Spirit Summoning System...

And all of this is made possible by the use of the Spiritron Calculation Engine.

Spiritron Calculation Engine... I'd heard rumors that the Atlas Institute was working on such a thing, but...

Yes. All of these great achievements in magecraft are accomplished by the Archibald family.

？！

(You there, don't let it show on your face!)

(Remember, poker face, Senpai!)

(Fou fou fou...)

So in the future, the Archibald family achieves all this?

Of course, this is only possible due to your astonishing leadership. Your later exploits at the Clock Tower...

...bring together a number of different academic factions to make this huge project, "Chaldea," a reality.

(If Director Olga Marie heard this somehow, who knows what she'd say...)

(Right, I don't even want to imagine it...)

Humph. I have no connection to the Atlas Institute. I dislike that group of eccentrics.

I would never work with those pessimists... Or so I thought, but... Heh. Hehehe.

I see... Well, it's not impossible, is it!?

？！

(Whaaaaat!?)

(Is the Lord of the Clock Tower an...)

Well, I was just thinking that the Evocation department and Mineralogy department weren't enough for me to get the upper hand in the academic world.

I was thinking perhaps it was time to find some new research. Yes. I'm surprised I had such skills in that direction, though.

Hmm. I guess even in my old age I can still pull off some new tricks, huh?

(What!? He's not the kind of person I thought he was. He's not, right?)

Amazing! Yes, I always believed in you.

Right now, you may be struggling, but in the future you'll achieve great things!

Of course, it's not only your technological achievements, but the financial backing provided by the Sophia-Ri clan.

The vast amount of funds required for Chaldea was only available due to the loving relationship you have with your future wife.

Aww, shucks. Hehe. I've dedicated my whole life to magecraft, so I don't know if I could be a family man...

At least, I didn't until now! I see! Fwahahaha!

(Oh, so the reason Lord El-Melloi wanted to get the Lancer faction on his side first was that...)

(They were the easiest to trick, maybe.)

(...Fo-u.)

And so we've come here to make your future glory all the more certain, Lord Archibald.

But time travel brings with it certain restrictions on what you can do in the past.

We can't offer you too much aid, but when it comes to information...

Yes, with your intervention, I'll have the advantage over the enemy at all stages in the process.

The first thing you must do is eliminate Caster. The other Masters don't know where he is.

If you can launch an attack first, the additional Command Spell the Overseer promised will be yours.

Wonderful! So I'll get a fourth Command Spell before I've even used one?

Hahaha! This battle's as good as won!

I joined this battle mostly on a whim, but if my future descendants are intervening...

Perhaps there's more meaning to this than I thought?

Please just keep in mind that such possibility cannot be ignored.

We can only speak to events that have already been decided when it comes to our intervention.

We must remain silent about anything that has not been observed by anyone in this temporal axis.

Otherwise, the ripples caused by the change of history will grow too great, and may activate the Counter Force.

Hmph...

Our very intervention has caused the future to change and lose its certainty.

What happens now is unknown to us as well.

These secret spells enter the realm of True Magic, and so they aren't that easy to use, huh? So I guess it all depends on how you use them.

We're almost at Caster's workshop. This is where it gets rough.

We've already passed the boundary, it seems. Something's coming!

HISS!

Caster's pet familiars.

He has a powerful Noble Phantasm, but is weak as a mage. However, in large numbers these things pose a threat.

Hmph. If it's giving such power to scum who can't even keep their magecraft secret...

I guess I'll need to personally secure this Fuyuki Grail.

Go, Lancer! Destroy all who would stand in my way!

As you wish!

Senpai, we're being left out of this for some reason, but we have to fight, too!

？！

Fou, fou!
