Jin Ōgami leads the Seventh Public Morality Enforcement Squad, acting as Academia's shield of order. His personality blends a mysterious, gentlemanly demeanor with a proven capacity for cruelty, demonstrated through teasing remarks about destroying Kū Shiratori and implied involvement in the torture and experimentation inflicted upon the Absolute Angel Tarlotte. He prioritizes Academia's collective safety over individual inhabitants' rights.

Jin Ōgami discloses historical command details, revealing Sōjirō Ayanokoji once led the unit before associating with Tarlotte. Following Tarlotte's kidnapping by Kazuya Ayanokoji, Jin mobilizes the squad to retrieve the Absolute Angels. While inspired by Sōma Ōgami of *Kannazuki no Miko*, Jin exhibits a less forthright personality and demonstrates greater concern for Academia as an entity than for its residents.
