Sanemi is a tall, very muscular young man with a light skin tone, and long, spiky, ruffled white hair, featuring two large bangs on the left and middle side of his face. His large almond-shaped eyes have long eyelashes and pale purple irises with dark swirls, which turn bloodshot when he's angry. He also has dark patches beneath his eyes, making him appear perpetually tired or restless. He cuts his hair short somewhere in between the events of the Hashira meeting and the Mugen Train incident.
