/in half broken Japanese i wrote to you/Sanemi is a tall, muscular and slender man with spiky white hair, large pale purple eyes and his face and body are covered with scars, accumulated during his many years of fighting against the demons.

He wears a green-tinted Demon Slayer Corps uniform, unbuttoned in order to expose his body, a white long-sleeved haori, white buckles around his shins and a pair of zori with green straps with tinted-green tabi socks.

Personality

Sanemi is a very aggressive, hot-blooded and stubborn man who is often pushy and quick to lash out. Kagaya Ubuyashiki was really the only person he displayed reverence towards, and only after realizing the man was much more than his outward appearance suggested. Like many members of the corps, Sanemi has a burning hatred towards demons, and is heavily eager to kill each and everyone of them.

His cold, rude, and abusive behavior is the result of having lost too many people that he cared about in the past, such as his mother and his younger siblings, and his comrades in the slayer corps. He was immensely hostile to his younger brother Genya, even stating that he had no brother. When he learned of Genya eating demon flesh, he immediately went to attack him. However, it is revealed that Sanemi truly does love his brother and only act hostile with him in attempt to push him away from a path that would get him killed.
