Series: Fushigi Yuugi OVA
Age: In disguise, 15... though he is a demon - so he is older.
Notes: He is one of Tenkou's Demon Kings, who is working towards ruling both the book and the real world. He disguises himself as a freshman in Miaka's school and uses his mind-control power against her and the students. He is also in quite the incestuous relationship with his sister, Miru.
