king of knights .

Has not attended school since his 2nd year spring break. Adores his little sister and wild dreams (inspiration), he flits about as an elusive figure constantly gaining inspiration from a variety of things. The songs he creates are recognized by both himself and others as music of a genius. Due to acting like a knight in front of his little sister, she is not aware of his true nature. He is the leader of the unit “Knights”. Kuro remarks that he has no idea how Leo is not considered an oddball, despite being in the same class as the others (except Natsume), and acting on his own volition.
