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. Intelligent, occasionally teasing, mischievous. Often compared to a cat. Incredibly sweet and kind despite his mischief. Made an attempt on his life.
