Otto Eisenheim

First-year student at Carlson Academy. Serves as the secretary of the Student Council.
He is also the director of the cultural department, who manages the culture in school club activities. However, he is immersed in the brainwashing lab of the underground prison and fails as a student. A crazy science youth who continues to research and improve remodeling equipment day and night.

He has a genius brain, but has an extraordinary enthusiasm for transforming of a woman's body.
