FGO System in the Type-Moon World

"Uncle, Mom says you should come inside."

At Sakura's voice, Reiji paused.

He had been leaning against the doorframe, ready to leave without a word.

But now, he turned his head.

Beside Sakura, clutching his sleeve, stood another young girl.

She was pretending to admire the scenery, but her occasional glances at him were far too obvious.

Even without being told, Reiji knew exactly who she was.

Tohsaka Rin.

Aside from the two girls, a graceful woman stood at the end of the stone pathway leading into the courtyard.

She gently brushed her hair back, her expression both elegant and warm.

"I don't know if you are my husband's friend or foe…

"…but may I invite you inside, even just for a moment?"

Her voice was soft, yet there was a quiet resolve behind it.

This woman—Tohsaka Aoi—was the wife of a magus.

And as such, she had long since come to terms with the realities of the world.

Otherwise, she could have never ended up with a pure magus like Tokiomi Tohsaka.

Was she unaware of the arrangement that had given Sakura to the Matou family?

Of course not.

She knew everything.

And yet—she had never protested.

She was a kind mother, but she had accepted her husband's decision.

But now, the very daughter she had reluctantly parted with…

Had been brought back home by an outsider.

It was only natural for her to wonder—

What exactly was going on?

If not for the presence of her two daughters, if not for her uncertainty about Reiji's abilities as a magus—

She might have contacted Tokiomi immediately.

But the Tohsaka estate was under surveillance.

Surely, Tokiomi had already been informed of Reiji's arrival.

Thus, Aoi decided to stall for time.

If Reiji was an enemy, Tokiomi would soon arrive.

If he was a friend, then at least the Tohsaka family wouldn't have displayed poor hospitality.

But what Aoi didn't know—

Was that Reiji had already seen through her reasoning.

To Sakura and Rin, who looked at him with grateful eyes, he could be kind.

But to a woman already plotting against him—

He couldn't muster a shred of interest.

"No need."

His response was immediate.

"If I wanted to find you all, I could do so easily."

He lightly patted Sakura's head.

Then, without another word—

He turned and walked away.

Aoi Tohsaka stood still, confused yet relieved.

Then, without hesitation, she immediately contacted her husband.

And when Tokiomi heard what had happened—

His eyes widened in shock.

Even his usual graceful smile vanished.

For the first time in a long, long time—

Tohsaka Tokiomi lost his composure.

His wife and daughters—

Had been found by his enemy.

And worse—they had spoken with him.

Leaning back in his chair, Tokiomi rubbed his temples.

For a long while, he simply sat there, eyes closed, gathering his thoughts.

When he finally opened them again, he immediately called an old friend.

"Risei… is Kirei back yet?"

A pause.

Then, Risei Kotomine responded.

"…Yes. He has returned."

Risei was puzzled by Tokiomi's sudden urgency—but he didn't question it.

Instead, he simply answered as requested.

And upon hearing that his prized student had returned, Tokiomi let out a slow breath.

For a brief moment, his hand trembled.

Then, his fingers steadied, and with one final inhale—

He regained his elegance.

"Then come over at once."

His voice was calm, but beneath it was a smoldering intensity.

"There's been a change of plans."

"Until the war begins, do not engage the magus."

"We will hold our ground. Once our preparations are complete…"

His eyes darkened.

"We'll settle this when the time is right."

Meanwhile…

Tohsaka Tokiomi's scheming was the last thing on Reiji's mind.

Instead—

He was preparing for his next move.

Unlike Matou Zouken, who had been a regular magus, killing him had yielded no Saint Quartz.

If he wanted more, there was only one way—

To kill Servants.

But first—

He needed to test something.

So, before the Holy Grail War...

He would try killing a Master.

If it earned him Saint Quartz, that would be ideal.

If not, at most, it would simply add more chaos to the Fourth Holy Grail War.

Other transmigrators might fear making such changes, but Reiji Souma?

He wanted to live freely and authentically—so he simply didn't care.

As for his target, he had already made his choice.

At this point, Waver and Kayneth had yet to arrive in Fuyuki.

The Tohsaka family? Too much trouble.

Considering all that—only one person fit the role perfectly.

A future Caster Master.

A serial killer lurking in Fuyuki City.

—Uryuu Ryuunosuke.
