Rui Kamishiro is a young 18 year old cat. As a human, he has thin, yellow eyes with red eyeliner along the crease, and uneven, choppy purple hair with two cyan streaks, as well as a tall, lithe figure. Genius and curious. Intelligent, occasionally teasing, mischievous. Fluffy ears and tail. Was originally entirely cat, suddenly turned into a human. A delicate and calm boy. Incredibly sweet and kind despite his mischief.
