When Yuta finds out Izumi's true colors, he attacks and tries to exorcise Yuta while Izumi reveals he was the one responsible for all the deaths, including the fathers of Yuta and Sarai. He then exorcise the ghosts of those victims, disguising himself as a masked exorcist to keep them from possibly saying anything. He even takes part of the experiments that were responsible of the deaths of the hundreds of corpses found in the lake. Part of the hierarchy and assassin of the Society of Eight, Izumi intends to find out the secret of immortality, and personally murders anyone who stands in his way. Occultic Nine: Kouhei Izumi(n) at first appears as a friend, but in actuality is a sadistic and cruel murderer.Mikaze was a manipulative sociopath with a wide sadistic streak with no reservation about murdering anyone who got in the way of her omnicidal plans. After exposing her true nature, Mikaze paralyzes Fumiaki after he wears out his use and promises to give him a torturous death, and utilizes her cult of brainwashed innocents to try and kill Maya and her friends, succeeding in murdering vice principal Chihiro and nearly attaining her goal of unleashing Hell upon the world.

Mikaze is responsible for the periodic monster attacks that have led to numerous deaths, and directly seduces time agent Fumiaki into doing her bidding. Disguised as a chef at a curry eatery with no apparent connection to the occult, Mikaze attempted to murder then-principal of Waldstein Academy Jun'ichiro to remove him as a threat to her own designs, and targeted his daughter Maya shortly after apparently killing him. Occult Academy: Mikaze Nakagawa appears sweet and kindhearted, but is actually a black mage with a penchant for seduction and a desire to open a gate to Hell and obliterate the world.
