Rindou is of average height and a lean build with neckline-length blond hair in a curtain style that he often wears down but would occasionally put up in a bun. He has purple downturned eyes, blond eyebrows, and a matching tattoo with his older brother on the right side of his back and chest, beginning from his nape and collarbones and ending at his foot. Rindou frequently wears a pair of circular glasses, a silver earring on his left ear. Rindou would also wear a black version of the Tenjiku.
