A Certain Magical Index: My Reincarnated Girlfriend

Fundamentally, science was not just something found in textbooks or references. It was not something unknowable without parental or teacher guidance. Essentially, everything forming this ordinary world was considered science. For the young Enshuu, she could basically learn from anything. Her surroundings provided infinite study materials, from the dust particles floating in the room to the texture of a plastic cup, all became mediums enhancing Kihara Enshuu's intelligence...

...

So, to successfully separate 'science' from the 'Kihara' Clan, there is no other way but to destroy the entire world completely.

The overly talented Kihara Enshuu roamed the ocean of science without a teacher.

Freely and joyfully.

Rather, it was the purest and most malevolent form, untainted by good or evil, and without boundaries...

It was this very Enshuu that was rescued by the Kihara Clan not long after.

In fact, the Kihara Clan had long known where little Enshuu was taken and who the kidnappers were, but they never sent anyone to rescue her. They merely wanted to experiment whether a member of the Kihara Clan could truly become a 'Kihara' without any education. Kihara Enshuu's performance passed, so they sent someone to rescue her.

As for the kidnappers, they all ended up as guinea pigs on the Kihara family's experimental table.

Originally, if it were just this, Enshuu would have lived her life as a tool for the Kihara Clan until death.

However, that summer, she met him...

It was on a scorching morning that she, for the first time, defied the will of the Kihara Clan and left the research institute. Unfamiliar with language, she didn't know how to comprehend this beautiful yet strange world. She simply stood dumbly on the street.

Looking at the passersby with confusion and helplessness.

Enshuu didn't know why she ran out of the lab nor what to do after coming out.

She just wanted to go out and see.

Then, someone spoke to her.

"Excuse me, little sister... can you give big brother some directions?"

It was a black-haired, black-eyed boy, several years older than Enshuu.

He seemed a bit awkward, probably feeling embarrassed asking directions from a little girl.

His gaze was clear, and his eyes looked at Kihara Enshuu with excitement but without a trace of evil intent, purely appreciative.

Not understanding language, not knowing any characters, only using her invented 'characters' and speaking a 'language' only she understood, Enshuu didn't know what the boy was saying but felt he meant no harm. Hence, she looked at him blankly.

Normally, when encountering a little girl who could not speak, most people would stay far away.

Others might call security or the disciplinarians.

The boy however, seemed worried about Enshuu's safety and stayed by her side. Although he was also lost, he tried hard to hold her hand and find someone who recognized her. He checked with security and disciplinarians, but Enshuu's information was not in any database... after all, the Kihara Clan members' information would never appear in the database.

At this point, most people would give up and leave her to the security or disciplinarians.

However, the boy chose to take her away.

He took her to his student dormitory...

Not knowing any written characters or language, little Enshuu did not understand why the boy was so good to her, but she genuinely enjoyed the care.

This was something she had never felt with her kidnappers or in the cold research institute with the Kihara Clan.

After discovering that Enshuu did not know a single word, the boy became her teacher, teaching her to write. The first word she learned to write wasn't her own name, but the boy's name, 'Nanaya Kiryu'.

The first sentence she learned and recited also included the name Nanaya Kiryu.

Living in Kiryu's student dormitory for over a month, Enshuu used her exceptional talent to learn all the languages and characters he taught and gave her access to in that short time.

This moment was the most precious time of her life!

Infact, it was the only moment that she truly enjoyed her life!

Here, she learned many things the Kihara Clan deemed unnecessary for her to learn...

However, the good times didn't last long, and the Kihara Clan came for her.

They wanted to take her back, and naturally, they intended to eliminate Kiryu for meddling in Kihara family affairs. Enshuu found an opportunity to escape, crying and shouting for him to run. Seeing her unwillingness, Kiryu, who had the chance to escape, chose to stay, standing in front of her, facing those Kihara Clan's lunatic scientists alone.

Then, Kiryu was killed...

With no special abilities, only some martial arts skills, he was barely stronger than an ordinary person... how could he possibly fight the Kihara Clan?

He died silently, like a small wave in the ocean, quickly returning to calm.

Apart from Kihara Enshuu, no one would mourn him, feel sad for him, or be angry for him!

The only person in the world who was good to her was dead!

Killed by those with whom she shared her surname, 'Kihara'!
