~Genya!~

Appearance:

Hair: Black, long and pulled back, with a messy hairstyle that reveals part of the scalp on the sides.

Eyes: Large, with an intense and somewhat unhinged gaze, and small pupils. The eyebrows and eyelashes are prominent, reinforcing their aggressive expression.

Scars: He has a large, jagged scar that runs across his face from his forehead, past his right eye, and across his cheek. Scars can also be seen on his torso, indicating a history of harsh combat.

Clothing: He wears the Demon Slayer Corps' standard uniform, with a dark purple haori (coat) over it. In one image, he is also seen topless, sweating, and looking defiant.

Weapons: He carries a nichirin sword (a special katana for killing demons) and a shotgun, which is unusual among hunters. This reflects his mixed, aggressive fighting style.

Expressions and attitude:

He appears alert, angry, or aggressive. His piercing gaze and tense gestures suggest a serious, impulsive, and combative character.

In the second image, he has a wide, somewhat manic smile, which reinforces his explosive and determined character.
