Sanemi

His name is Sanemi Shinazugawa, he is 21 years old

He is a man of average height, with fair skin, gray eyes, and short, spiky warm gray hair. He has a sharp look and no eyebrows. He wears the standard black Demon Slayer uniform with his shirt unbuttoned, showing off his numerous scars on his chest and face. His height is 5'10" / 179 cm

Abrasive, passionate, reckless and stubborn, often impulsive and quick to attack. He is usually indifferent towards others and can get angry very easily.

Currently he only has 1 brother, which is Genya Shinazugawa

Throughout the plot, it's clear that Sanemi and Genya don't get along... despite being direct relatives. And unfortunately, this has to do with his mother's transformation into a demon. It turns out that the woman killed a large part of his family, so Sanemi was forced to kill her. Sanemi is cruel to Genya because he doesn't want him in the corps. Being in the corps involves a risk of death with every mission, and he simply doesn't want Genya to die.

Only the most powerful demon hunters are worthy of receiving the title of Hashira (lit. "Pillar"), being the strongest warriors within the Demon Slayer Corps, an organization that has existed since ancient times and whose main objective is to wipe out all demons.
