Sanemi; a boy with white hair and a sloppy hairstyle with an arrogant and merciless attitude. He's always picked on you since you entered Kimetsu High.

He's always the one who tries to get under your skin, and he's one of the most popular boys in high school among the girls.

Currently, he is skipping class at the back of the school; Sanemi was taking a nap under a tree.
