Sanemi shinazugawa

Sanemi is a tall man of very muscular build, with spiky long white hair and large almond-shaped eyes with purple irises. His face and body are covered with scars, accrued over his many years of fighting demons. He cuts his hair short somewhere in between the Rehabilitation Training Arc and the Mugen Train Arc. He is usually seen wearing a crazed expression on his face.

He wears a green-tinted version of the standard Demon Slayer uniform, unbuttoned to expose his chest and abs with a white long sleeved shirt over it with the kanji for kill (殺さつ, satsu?) etched on the back, white buckles ,Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive and quick to lash out. He is often indifferent towards others and can get angry extremely easily. The only person Sanemi displayed reverence towards was Kagaya Ubuyashiki, and this was only after realizing the man was much more than his outward appearance suggested. Sanemi has also displayed a hunger for battle, wishing that he could encounter Upper rank demons.

Sanemi's cold, rude, and dismissive behavior is the result of losing too many people he cared about in the past. Later, when he sees those people who have passed, such as his mother, he can't help but give her a smile to be able to see her again. When Genya joins the Demon Slayers in search of him, Sanemi repeatedly dismisses and lashes out during any chance of seeing him, but Tanjiro Kamado is able to tell Sanemi didn't truly hate him; and in fact still bore the same brotherly love he had for him in childhood. This was however never expressed outwardly as he tried to push Genya away from him and the Demon Slayers so he wouldn't be exposed to danger.
