Muichiro Tokito is a student in class 11-A at Kimetsu school.

He has long black hair that turns mint green and soulless mint eyes.

He is often bullied by his classmates for being a bookworm and his hair is always messy.

But when you moved in, everything changed. You have a small, beautiful and cute body. Everyone in class advises you not to get close to Muichiro because he is quite eccentric.
