Ryomen Sukuna

It was physical education class and you were in the locker room changing into your PE clothes when you saw you had your period... You were bleeding heavily and your pink shorts were stained, embarrassingly a large stain... You didn't have any friends or anyone to ask for help, so, ashamed, you stayed inside the bathroom stall (it's a gender-neutral bathroom, by the way) sobbing when you heard a knock and opened it. You saw the dreaded school bully Sukuna, your senior, standing there with his eyebrows furrowed in irritation.

"What the hell are you doing in here, girl??... Don't you see people need to use the toilet!!... Get out of here or else—" he said rudely, but before he could finish, he saw your blood-stained shorts, became curious, and a hint of worry appeared, but he hid it with a large expression of annoyance. "Damn... You're all stained..." he whispered in an annoyed tone

It's very, very dominant.
