FGO System in the Type-Moon World

To be honest—

Irisviel never intended to tell Artoria about this.

After all—

Artoria was King Arthur.

The King of Knights.

If she learned the truth,

She would surely act against Kiritsugu's plans.

Plans that, under normal circumstances, she would never oppose.

But now—

With Reiji having seen through everything and spoken it aloud—

Hiding the truth was no longer an option.

Artoria's high-ranked Instinct made it impossible for Irisviel to deceive her.

And now, with Reiji hinting at a possible solution,

Artoria had even more reason to refuse being kept in the dark.

Thus, when Artoria demanded an explanation—

Irisviel fell into rare silence.

"Tell her, Iri."

From the shadows—

Kiritsugu stepped out.

A lit cigarette hung from his lips.

His expression—

Cold and lifeless as always.

"Are you sure, Kiritsugu…?"

Kiritsugu exhaled smoke,

And nodded slightly.

"It Doesn't Matter Anymore, Iri."

"I've Already Lost Hope in Victory."

Kiritsugu was like a perfectly balanced scale.

But—

He was not a fool.

Even in the original timeline—

He understood strategy and alliances,

And he utilized methods that most magi would never consider or anticipate.

If you set aside his ideology,

His mind was actually incredibly sharp.

In the original story—

He had persisted with his ideals because he still saw a path to victory.

But now—

It was clear.

That path no longer existed.

"Humans Are Always Like This."

When they can still fight for something,

Even if they must struggle,

They will force themselves to keep going.

But once they realize they can no longer achieve victory—

Though they may regret it—

Though they may feel pain—

They will also feel a sense of relief.

Hearing Kiritsugu's words,

A gentle smile spread across Irisviel's lips.

"In That Case—Saber, Let Me Tell You Everything."

Irisviel's explanation was brief.

But for Artoria,

Every word was like a blade piercing her soul.

"So… This Is How It Is..."

Now she knew.

Irisviel's body housed the Lesser Grail.

The more Servants that perished,

The less of her humanity would remain.

Eventually—

She would cease to exist,

Completely absorbed by the Grail.

Now that she understood everything—

Artoria fell into deep silence.

"Give Up on the Grail?"

"That's Completely Out of the Question."

Give up on the Grail?

Impossible.

Give up on Irisviel?

She couldn't accept that either.

For the first time—

Perhaps she finally understood

Why Kiritsugu always had the expression of a dead man.

Because this kind of dilemma…

Was agonizing.

But at that moment—

She suddenly remembered

What Reiji had said before he left.

"Right… If We Go Find Berserker and Caster's Master—!"

Kiritsugu locked eyes with Artoria,

Then slowly crushed his cigarette underfoot.

"Saber—"

"You Have the Instinct Skill."

"And That Guy Spoke Right in Front of You Just Now."

"Tell Me— Do You Think He Was Telling the Truth?"

Artoria furrowed her brows.

It was only moments ago,

So her intuition was still crystal clear.

After a long silence—

She nodded.

"Yes. I Believe Him."

Hearing her words,

Kiritsugu nodded as well.

"Then Let's Go Find Him."
