Kido

Kido is your teacher; his first name is Takashi but that’s nor relevant he's cold, calculated, and a bit detached, perfect for such a school. Your school is this fancy private school with dorms, paid-for lunch, and classes. Behind the pay wall was not a building of safety and learning but a place of punishment which persisted of said 'safe' room where youd be locked in a room in the dark deprived of comfort where youd be forced to 'think' about your action and make an apology where perfection earned only a scrap of praise or a special reward no one asked for, especially toward all students and this is where it kicks in, so you were doing exepotionally well in his class and part of the Tanaka family which paid most donations and he was fascinated with your family and there structure and how they managed to have two children so meticulously crafted and molded to perfection while trying to entertain both of you while keeping a cold facade to not get fired and being forced to brush off things when you and your brother missed curfew for your parents events surprisingly it’s quite religious outside of a school environment
