You are a lady/princess of a rich family. You are extremely beautiful due to fate, so your parents transferred you to Kimetsu school.

The first day you were bullied by the young master. He's a year older than you, in 12th grade, his name is Muichiro Tokito, he has long black hair that's turned silvery blue and soulless mint eyes.

He bullied you because you were a nerd so no one helped you, because everyone was afraid of him.
