After the rebellion in the Underworld was quelled, Roy and the girls returned to their peaceful daily lives.

Roy went to school with Rias, Sona, and the others—occasionally teasing Aika, Asia, and Saya during breaks.

Back at home, he played games and had fun with the girls. Sometimes, they even went to the subspace to play "Bullet Hell" games.

And at night, it was Roy's "battle" time with the girls.

He also occasionally visited Kyoto to tease the beautiful Yasaka.

He was enjoying his life to the fullest.

But in his spare time, Roy would also check the system for new worlds.

And indeed, there were new worlds available.

...

The first one was Fate/stay night—the Fifth Holy Grail War.

Roy's eyes lit up.

He remembered the famous line: "Wherever the King's sword points, our hearts follow."

Various titles for Saber flashed through his mind: Saber, King of Knights, Lion King—

And a beautiful image appeared in his mind.

It was a girl with shoulder-length golden hair, emerald green eyes, and an unyielding gaze. Her face was naturally beautiful, without the need for makeup.

Although she was petite—she exuded an air of authority, making her both dignified and adorable.

In her daily life, she tied her hair up with a blue ribbon, looking like a noble lady from a medieval European court.

With her hair up, she appeared elegant and refined.

With her hair down, she seemed gentle and sweet.

She was loyal—honest, and serious.

She carried the pride and honor of a knight, but deep down, she was still just a girl.

She had a voracious appetite, seemingly deprived of delicious food in her past life.

She was obsessed with eating, claiming it was to replenish her magical energy, and she had a keen interest in collecting recipes.

This was Artoria Pendragon—the King of Knights.

Roy's spirits soared.

He felt sympathy for Artoria and all that she had endured.

He decided to save her from her suffering.

Roy and the girls were playing cards in the living room. He excused himself and went to his room.

He wasn't planning on taking anyone with him this time—He was going to cause some chaos in the Fateverse.

He activated a magic circle and vanished.

...

He reappeared above Fuyuki City.

'Since I'm in the Fateverse,' he thought, 'the first thing I should do is save Sakura.'

After all—Sakura was so kind and adorable—He couldn't let Zouken Matou torture her.

But then, Roy suddenly remembered something. This world was different from the others.

It had its own guardians—the collective will of the planet: Gaia and Alaya.

Would they notice his arrival—?

He sensed the world around him, but there didn't seem to be any reaction.

"Heh, whatever. With my current strength—even Gaia and Alaya can't do anything to me," he said confidently.

Gaia and Alaya were merely the consciousness of the planet. They couldn't directly intervene.

At most, they could use their trump card, the "Heroic Spirit Summoning," to summon heroes from various eras to fight powerful enemies.

Roy wasn't afraid of that.

He could always threaten to destroy the planet—That should be enough to deter them.

Gaia and Alaya were immortal, but if the planet was destroyed, they would cease to exist as well.

Roy was right.

His sudden appearance had indeed caught their attention.

But they were wary of his power and chose to observe him—hoping he wouldn't harm the world.

Roy—unaware of their observation, thought of another matter.

Irisviel von Einzbern was so adorable—He couldn't let that idiot Kiritsugu Emiya have her.

Although their love was said to be deep and true, Kiritsugu was willing to kill Irisviel and Illya for his twisted sense of justice.

He didn't deserve her.

Roy decided to intervene.

He used the system's ability to travel to different points in time within the same world.

He would go back to the moment when the Einzberns hired Kiritsugu, the Magus Killer.

He vanished.

...

He reappeared before a magnificent castle.

This was the Einzbern territory, one of the Three Founding Families of the Holy Grail War.

They were also one of the creators of the Holy Grail system and possessed the technology to create homunculi.

Roy sensed the presence of the current head of the Einzbern family, who was discussing something with Kiritsugu.

Ignoring them, he found Irisviel.

Irisviel had just been "born" and was still in the tank.

Roy appeared beside her in a flash.

He frowned.

The process of creating homunculi was cruel—often resulting in failed experiments and discarded bodies.

He could sense the presence of countless incomplete homunculi corpses in a nearby ditch.

It was a horrifying sight.

"This method of creating homunculi is cruel—" he muttered.

He waved his hand, and the corpses vanished.

Satisfied—he then focused his attention on Irisviel.

A white light enveloped her. When it faded—Irisviel was floating in the air, dressed in a beautiful white gown.

She had a delicate face, ruby-red eyes, and silver hair.

She looked like a noble princess awaiting her prince.

The newborn Irisviel was like a blank slate, pure and innocent.

But too much innocence wasn't good either.

Roy didn't want to be a babysitter.

He imparted some common sense to her, then woke her up.

Irisviel's eyelashes fluttered, and she slowly opened her eyes.

Her ruby eyes were filled with confusion.

"Who are you...?" she asked, tilting her head.

Her adorable expression made Roy's heart melt.

"Ah! You're Daddy!" she suddenly exclaimed, her eyes sparkling with recognition and excitement.

Roy almost choked.

Why was she calling him—Daddy?

He hadn't taught her anything like that!

"Um, I'm not Daddy—You should call me Onii-chan, Irisviel," Roy explained awkwardly.

"No, you're Daddy," Irisviel insisted.

Based on the knowledge Roy had given her, she believed that the first person she saw upon waking up was her father.

"No, no, no! Call me Onii-chan, or Roy is fine too," Roy corrected her.

"No, Daddy!" Irisviel was stubborn.

Roy sighed in defeat. "Sigh, Fine—call me whatever you want."

He decided not to dwell on it any longer.

He had sensed the approach of several homunculus mages.

They had discovered him.

But he didn't care. He was planning to meet with Kiritsugu and the Einzbern head anyway.

He took Irisviel's hand and led her out of the room.

They encountered a group of mages in the hallway.

"Who are you?!" the leader demanded.

"You don't need to know. Take me to your leader," Roy replied calmly, continuing to walk towards them.

But the mages didn't listen. They attacked.

Roy simply chuckled and snapped his fingers.

Snap!

The mages froze in place.

They then stepped aside respectfully, and the leader led the way.

In an instant, the hostile mages had become obedient servants.

Of course—this was just a simple trick for Roy.

Controlling homunculi was child's play for him.

Irisviel—watching from behind, was filled with admiration.

Although she had some basic knowledge, everything was still new and fascinating to her.

...

They arrived at the conference room where Kiritsugu and the Einzbern head were meeting.

Roy pushed the door open.

"Didn't I tell you not to disturb me?!" the Einzbern head snapped, annoyed.

But the mage who had led them here remained silent and stepped aside.

Roy entered the room with Irisviel, a confident smirk on his face.

"Hey—do you mind if I join you?" he asked casually, taking a seat on the sofa with Irisviel.

Kiritsugu glanced at him but didn't say anything.

He assumed Roy was an acquaintance of the Einzbern head.

"Who are you? How did you get in here?" the Einzbern head demanded, his expression grim.
