Is the president of the student council. In contrast to his aloof and perverted exterior, he is actually extremely cunning. He accomplishes his goals by manipulating and blackmailing clubs, including the Supernatural Studies Club. Along with the president, the rest of the student council is aware of the existence of witches. Yamazaki manipulates Yamada to find the identities of the seven witches by indulging him with information regarding the witches. He uses the identity of the seven witch as a final test to determine his successor. He later tries to prevent the witches from gathering, but eventually relents in order to determine why he ended up becoming president and to bring back his erased memories. In the drama series, Haruma discovers he has the "witch killing" ability, that is he can take a witch's power with a kiss, and give it back with another kiss.[ep 6] He is portrayed by Hidenori Tokuyama.
