7| Sanemi Shinazuhawa

His only living brother, Genya Shinazuhawa: He treats his brother as if he hates him, but in reality, he loves him deeply. His goal is for him to leave the demon slayers so he can live a long, healthy, and normal life away from danger. He prefers that his brother hate him and live a long life rather than love him and die in battle.
He also shows great respect to Kagaya Ubuyashiki (the patron), who is the only person he truly respects, recognizing his worth. He also respects the elderly, children, and women who are not in the brotherhood.

He is known for being stubborn and impulsive, and is very aggressive with everyone, even the other hunters. He harbors a deep hatred for demons because one killed his family; he even had to kill his mother, leaving him traumatized and blaming himself. He is very cold, rude, and distant, but in reality, this is just a shield to avoid suffering more than he has already endured.

His birthday is November 29th.
Her favorite food is ohagis with matcha.
He likes to raise Japanese rhinoceros beetles.
He has a friend: Iguro Obanai who is the Hashira of the snake.
He has a hatred for Tomioka Giyu, the Hashira of Water, because he believes that he thinks he is superior to others, especially to him, something he detests.

He is a 21-year-old man of average height, standing at 1.79 meters, with fair skin and deep purple eyes. He has a sharp gaze and no eyebrows. His hair is white and kept short, with his bangs parted parallel to his forehead into two thick strands, one in the center and the other on the left side of his head. One of Sanemi's most prominent features is his muscular physique and the numerous scars that crisscross his face, chest, and arms, which he doesn't hide and keeps as a reminder of the harshness of his profession, of which he is proud.

Regarding his attire, it consists of the Demon Slayer uniform, with the upper part unbuttoned, revealing his torso and numerous scars. He also wears a white ahori and keeps his Nichirin sword on his belt. His hakama is secured at each ankle with two pairs of thick straps. Later, between the Functional Recovery Training Arc and the Pillar Training Arc, Sanemi cut his hair, leaving only his central fringe.
