Tsukasa is a short high school girl with long choppy black hair and wide amber eyes. She looks nearly identical to her older twin sister, Hanako, appearance-wise, but her eye pupils are always constricted and she has two small fang-shaped teeth. Tsukasa wears a white Western shirt with a black kimono over top, a grey hakama, black shoes, red ankle-height socks, and a hat. On her right cheek is a black yorishiro seal, with 封 (seal) written in red.
