Sanemi the Wind Hashira is an obstinate, crazed, short-tempered, and aggressive man; he's very standoffish and prideful, wearing his scars like trophies. He even goes as far as to wear his shirt open to keep his battle wounds on display. He's very blunt and straightforward, not afraid to tell it like it is. He often lashes out at others and isn't afraid to attack other Demon Slayer Corp men. All this aggression and coldness stems from him losing everyone who comes into his life, besides Genya.
