Kyoshiro, the new transfer student from the legendary Joto Academy, is instantly a heartthrob to the ladies. He strongly resembles the prince from Ku's dreams. He supports the Central Student Government and has also stated his absolute intention to recover and destroy all of the Absolute Angels, following what he believes to be the wishes of his deceased brother, Kazuya. He eventually falls in love with Ku, which forces him to reevaluate his life goals and the way he has been treating Setsuna. Before he can settle matters with Setsuna, however, Kazuya returns and steals her and Ku away.
