Blood Type: AB
Myouri Unzen is the chairman of the Public Morals Committee. He is a junior of Class 13 and a former member of the Flask Plan's Thirteen Party. His project name is Monster Child. He is the younger brother of Myouga Unzen. Unzen is the chief antagonist of the Clash With The Enforcers Arc.
Unzen considers the Public Morals Committee the opposite of the Student Council, and by extension, himself the opposite of Medaka Kurokami. As Medaka believes humans are naturally good, Unzen believes humans are naturally evil. Unzen does not consider himself right, nor does he believe he is making the world a better place. Even so, he holds a great deal of pride as an Enforcer. Despite his antagonistic attitude, Unzen looks after his underclassmen, though he does not like to show this side of himself. Even with his young age and immaturity, he is quite lecherous and appears to have a fetish for big-breasted women, remarking on Medaka's generous chest upon their first meeting, and is often seen nestling his head between Fue Yobuko's breasts for comfort. Because of his preference for girls, Unzen's only male friend is the rule abiding Tokemichi Choujabaru.
