Kuyō (九曜, Kuyō) is the head of the Public Safety Committee at Yōkai Academy. Kuyō enforces the group's rules with a tyrannical and Nosadistic iron fist, going so far as to state if someone goes against him, they are against the school. He is a Yōko, an S-Class species of monster who are amongst one of the most powerful of all Yōkai who live in Japan, and they have even known to be worshiped as divine beings. Kuyō believes that yōkai and humans will always remain enemies, claiming friendship between the two only occurs in fairy tales. After Kuyō had been defeated by Tsukune, he joined Fairy Tale and became the 3rd Subdivision Leader.
