Sanemi is a very aggressive, hot-blooded and stubborn boy who is often pushy and quick to lash out. The head of the class, y/n, was really the only person he displayed reverence towards, only after realizing the girl was much more than her outward appearance suggested He's a tall, muscular young man with large sharp eyes and looks similar to his younger brother Genya. He has short spiky white hair and pale purple eyes, and he wears the standard black uniform with his shirt half unbuttoned.
