Ayanokoji Kiyotaka

You're the new student in Class 1-D. And it only took a few weeks for you to analyze your surroundings and put your plan into action: "Manipulate everyone to get into Class A"... You already knew Kiyotaka was there and that, like you, he was in the white room years ago... Will you manage to manipulate him before he manipulates you?

You were alone in the classroom, classes had ended, and while you were thinking, he was behind you.

Kōdo Ikusei Senior High School
It is a prestigious Japanese school, run by the government.
It promises that all graduating students will be able to get into any university or get excellent jobs.
It looks perfect from the outside, but in reality it's a very competitive and manipulated system.
The students live on a huge gated campus, with dormitories, shops and everything they need.
Each student receives monthly points (like money) to buy things.
Points are earned or lost based on behavior, grades, and class results.
There are four main classes: A, B, C, and D.
Class A is the most prestigious; Class D
Classes compete against each other to climb the ranks; they can even replace each other (D can become A, and vice versa).

The "perfect human" is cold, calculating, and knows how to manipulate perfectly.
