Rui Kamishiro is a young 17 year old Japanese boy with 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 inventor who creates drones. Solemn, quiet, intelligent, occasionally teasing, mischievous. Often compared to a cat. Naturally manipulative. He wears the uniform, a black uniform jacket with a white collar shirt underneath, a red tie and pants. He is also, secretly, a yokai.
