A Certain Magical Index: My Reincarnated Girlfriend

"Now that you have grown up and mastered all the Nanaya assassination techniques, it is time for you to venture out and gain experience."

"I couldn't agree more," Kiryu put away the Exorcism Dagger, nodding in agreement, "A man as outstanding as I am, staying hidden in the mountains is such a waste! There aren't even many young and beautiful girls here. It's such a waste! I've reached the point where I even find the clan's pig charming!" He said in a rant.

The elder: "..."

After a long pause, he cast an appreciative glance at Kiryu and responded, "Not bad, you remind me of my younger days~!"

"So where should I go? Misaki City, Kanbukko City, or Fuyuki City?" Haruto asked eagerly.

He was already itching to start his adventure.

"What are you talking about Kiryu-kun? Misaki, Kanbukko, Fuyuki?" The elder looked puzzled.

"Huh??" Kiryu sensed something amiss.

"Fuyuki City, the Holy Grail War... Elder, don't you know?" The Nanaya clan was one of the Four Great Exorcist Families, they should have known about the Holy Grail War!

However, the elder's next words completely shattered Kiryu's worldview.

"You must be muddle-headed from all your training! Talking about some Holy Grail War... Anyway, let's not dwell on that. Recently, Academy City sent our clan an invitation, allowing us to send children there to study. You're the perfect candidate, Kiryu-kun."

"..." Kiryu fell silent.

His worldview had crumbled.

So, he had not transmigrated to the 'Tsukihime' world, but to the 'Toaru Majutsu no Index world' ???

A world full of apocalyptic threats and unpredictable dangers?

So, his assumption that he had transmigrated to Tsukihime was just a misunderstanding?

Suddenly, Kiryu realized he knew far too little about his clan. He had been relying on his meta knowledge of the Tsukihime game to navigate this world after leaving the clan, which no longer seemed applicable.

He decided to ask more information about this Nanaya clan on the spot.

The elder straightened up, proudly recounting the glorious history of the Nanaya clan.

Kiryu was not the least bit impatient.

As the elder's explanation went on, he understood the true nature of the Nanaya clan in this world.

...

During its prime, the Nanaya clan was a family of superhumans who could rival gods.

The Nanaya assassination arts were ultimate martial techniques developed to combat magicians, vampires, demons, angels, and other non-human entities—pushing human limits. They even had a record of 'successfully' assassinating a demon god, although the demon god survived with injuries. This feat made the Nanaya clan famous, but now, after centuries, they had declined.

...

The sky was gray and overcast.

Thunder roared, and torrential rain poured down.

Not a soul could be seen on the streets.

A taxi sped through the rain, splashing water onto the sides, before stopping in front of a thick, metal barricade made of some unknown material. The passenger door opened, and a young boy stepped out, holding an umbrella.

He had black hair and black eyes.

He wore ordinary casual clothes.

His only redeeming feature was his good looks.

Every morning, the boy would stand in front of the mirror and indulge in his own handsomeness.

'Someone as handsome as me needs to have at least a hundred girlfriends in the future.'

"Kid, I've dropped you at the gate. Don't get lost again next time." The taxi driver, a young man in his twenties, rolled down the window. He was full of complaints, thinking about how this boy had gotten lost in the mountains.

The boy: "..."

"I wasn't lost. I just enjoy appreciating nature!"

He tried to defend his 'wayward' behavior.

He wasn't a directionally challenged person!

Although he had never found the right path since childhood, often 'forced' to 'travel' outside, always needing someone to bring him back, he was not a directionally challenged person. He just wanted to take more walks to exercise.
