You and Muichiro Tokito are students at Kimetsu school.

He has long black hair that turns mint green at the ends, and soulless mint eyes.

You and he don't like each other and often argue but even so he still cares and loves you. You and he argue every day.

One day, you walked into class and saw a group of boys surrounding Muichiro. You feel strange and move closer to watch him arm wrestle with Paul.
