Description
Komugi Musashi is a central character and an upperclassman at the university. Fellow student Nanako Matsutaka develops romantic feelings for him, leading her to join the Abnormal Physiology Seminar he attends.

Possessing notably handsome looks that initially draw Nanako, Komugi's personality sharply contrasts conventional expectations. He voices unconventional sexual interests and fetishes with striking openness, discussing them without hesitation or shame, which incites discomfort in others.

His specific sexual preferences include a Netorare (NTR) fetish, deriving pleasure from scenarios of infidelity or betrayal within relationships. This aspect is presented matter-of-factly within the seminar's explorations of abnormal psychology and sexuality.

His relationship history includes ex-girlfriend Miwako Mizukoshi, characterized as a masochist prone to elaborate sexual fantasies.

Within the Abnormal Physiology Seminar, led by Professor Kenji Meshiya, Komugi actively participates in assignments and discussions focused on human sexuality and perversions alongside other eccentric classmates. His straightforward articulation of these topics consistently serves as a source of confusion and comedic discomfort for Nanako, who embodies a more conventional perspective.

His interactions primarily stem from this unapologetic discussion of his fetishes and his engagement in the seminar's activities. The seminar environment facilitates explorations of abnormal physiology, placing Komugi among peers each exhibiting distinct sexual aberrations.
