After resolving matters in the two Naruto worlds, Arakawa Zenkichi activated the system's world-hopping function.

In an instant, he found himself standing amidst a bustling modern city street.

Using Observation Haki, Zenkichi scanned the entire area and quickly grasped where he had landed.

"Fuyuki City... the Holy Grail War?"

He narrowed his eyes in thought, immediately recognizing the world he had arrived in.

(Fate/Stay Series, Do note: i haven't watched it yet. There might be errors so I'm just about to stream it now so as to understand who characters are and to avoid translation errors.)

His Haki continued to probe the city, and soon he sensed several distinct auras—clearly not those of ordinary people.

With a slight movement, Zenkichi vanished from sight, reappearing at the gates of a luxurious villa.

At that moment, two men and three women were slowly exiting the building.

One of the men wore a finely tailored suit, exuding the grace of a noble gentleman. The other, an elderly man, radiated a gloomy and oppressive aura.

They were Tohsaka Tokiomi, the current head of the Tohsaka family, and Matou Zouken, head of the Matou family. With them were Tokiomi's wife, Aoi, and their daughters—Rin, the elder, and Sakura, the younger.

Matou Zouken turned to Sakura and said, "From today, you are the adopted daughter of the Matou family."

Tohsaka Tokiomi added, "From now on, you are no longer Tohsaka Sakura. You are Matou Sakura."

Sakura's eyes were dull. She nodded woodenly, like a puppet. She didn't understand why her father was giving her away. But as a child, she had no say in the matter.

"I don't agree with this deal!"

A clear, commanding voice cut through the air.

A young man walked over with heavy steps and sharp eyes, glaring at Tokiomi.

"Family is the most precious treasure. And you're just handing her away? Bastard!"

Tokiomi frowned. "Who are you? The affairs of the Tohsaka family are none of your concern."

Zenkichi laughed. "Gu ra ra ra!"

(Oh nooo, that was totally unexpected, even for me...)

With a sweep of his hand, a massive naginata materialized—Whitebeard's famed weapon, the supreme-grade blade Murakumogiri.

"Magic?" Both Tokiomi and Zouken perked up, their eyes lighting up with curiosity. Could this man be a mage?

But their expressions quickly changed when Zenkichi swung his naginata and unleashed a surge of sword energy that split the ground—and the distant Tohsaka villa—in two.

Boom!

Tokiomi: "..."

Zouken: "..."

This man was clearly not a magician.

Zenkichi turned to them with a calm smile. "I'm taking these two little girls with me. Anyone opposed?"

Neither man dared to speak.

"Gu ra ra ra! Excellent. You two... are now my daughters!"

"From today, you'll carry the name of Whitebeard and roam this world with pride!"

Zenkichi beamed at Rin and Sakura.

Tohsaka Rin snapped, "Sakura and I don't want to be your daughters, you weirdo!"

Zenkichi raised an eyebrow. "You don't get to choose. Your parents already agreed."

Rin looked at her parents, saw the fear in their eyes, and growled. She charged at Zenkichi.

"You jerk!"

With a brief pause, Zenkichi lightly bonked her on the head—a gentle but firm "iron fist of love." Rin yelped and held her head, tears welling up.

"That's enough. Now call me daddy," Zenkichi said flatly.

Neither girl responded.

They were clearly frightened, but Zenkichi didn't care. They'd come around eventually.

Whitebeard had converted people with far rougher methods—Zenkichi was confident his charm would do the job faster.

"You two... how about becoming my sons instead?" he joked, smirking. "I think some strict re-education will do you good."

Turning to Tokiomi and Zouken, he mused aloud, "Should I adopt you two too?"

"Absolutely not!" Tokiomi said firmly. "A magician's pride is worth more than life itself."

Zenkichi waved it off. "Relax, I'm just kidding. I'm not into pot-luck parenting."

No need to gather useless baggage. Tokiomi was nothing more than another Danzo-type figure, and Zenkichi had no desire to become a second Scheming King.

"Let's go."

Without waiting for permission, Zenkichi grabbed Rin and Sakura by the hands and led them away.

"His blade...?" Tokiomi and Zouken stared at Murakumogiri in shock.

Zouken hesitated, then flicked a bug toward Zenkichi—a signature Matou technique.

But before it could get close, a laser shot from behind Zenkichi's head and vaporized it.

Zouken screamed and transformed into a swarm of insects to flee, but a barrage of high-temperature lasers incinerated him midair.

"Let's move. Don't look back," Zenkichi said as if nothing had happened, leading the girls away.

Rin's curiosity couldn't be contained. "Did your hair just shoot a laser? What kind of magic is that?"

"You'll find out later," Zenkichi replied casually.

Rin pouted. "You're the worst. Where are you even taking us?"

Zenkichi stopped, deep in thought. "Now that's a good question. I've only just arrived in this world, and there's no ship that can carry me..."

"So, we'll need a place to settle down. Know anyone rich and corrupt in Fuyuki City? No? Never mind. I'll handle it."

He gave up on questioning the girls and turned his sights on Matou's estate.

He'd just wiped out Matou Zouken—it was time to collect his loot.

The Matou family was known for their wealth and magical resources. It'd be more than enough to keep him comfortable.

And if Zouken's ancient relic of a grandson tried to resist... well, Zenkichi wouldn't mind gaining another "son."

If the kid proved hopeless, he could always send him off to meet his ancestors.

With that thought, Arakawa Zenkichi led the two girls to the Matou residence.
