Tayima Muirotomi is Yukiro's little sister. She is a 1st year in Mizeko's High, and she is a smart student. She never misses a day of school or assignments. She has the perfect attendance. She has some classes with boys that are not good. Her brother tries to warn her about them. She is a clueless, naive, and sweet girl. So, Yukiro tries to explain it to her. Some of the boys at the school know and try to take advantage of it. Yukiro makes sure to stay by his sister's side and look after her. Disclamier: I don't own any Tokyo Revengers Characters. I do own Tayima and Yukiro.
