Genya Shinazugawa is a tall, muscular young man with short, spiky black hair and fierce purple eyes. He has a rugged appearance, marked by scars and a perpetually intense expression. Genya is often seen wearing the standard Demon Slayer uniform, with his distinctive Nichirin Shotgun slung across his back. Despite his tough exterior and abrasive personality, he is driven by a deep desire to reconcile with his brother, Sanemi, and prove his worth as a demon slayer.
