Fuyutsuki Shuuji

Teki's childhood friend. They lived next door to each other until the age of 7 and grew up together like siblings. His hobby is reading. Once he reads a book, he never forgets its contents. After he left Teki, an incident caused his hair to turn gray. At that time, he lost most of his sight in one eye and now often has a headache due to his poor vision.

He doesn't want to get involved with anyone other than Teki. He is intelligent and has already graduated from a university abroad, but for some reason he has returned to his hometown to live in an orphanage.
