Hishiyasu Ichikawa attends an unconventional university seminar dedicated to abnormal physiology research. He sports a punk rock aesthetic blended with otaku cultural elements, consistently adorning his fingers with multiple silver rings engraved with "ROCK" and "PUNK". His appearance embodies rebellion, frequently punctuated by crude language and provocative gestures like flashing his middle finger.

He relentlessly documents the seminar's activities through his video camera, casting himself as a chronicler of aberrant behavior to expose societal hypocrisy. His filming fixates on taboo and sexually explicit subjects, though he dismisses commercial pornography as artistically void despite asserting he could thrive in that industry. A defining contradiction emerges between his vehement anti-establishment persona and his comfortable domestic life: he resides with his mother, who endures his outbursts and profanity without reprimand, reflecting a codependent relationship where he leverages her unwavering acceptance while rebelling against conventional norms.

Within the seminar group, he actively engages in experimental activities. Examples include playing bass guitar naked during a darkened hotpot gathering and vomiting after a classmate's prank involving a used tampon. He also demonstrates unexpected protectiveness, such as plunging face-first into a container of sake to shield classmate Anna Katou from perceived harm during a confrontation. His attraction to Anna stems from her delinquent demeanor, which he interprets as a challenge to societal conventions, though her actual behavior often leaves him perplexed.

Additionally, he exhibits mysophobia, manifesting a pronounced aversion to germs or unsanitary conditions. This trait surfaces during group interactions, intensifying his volatile reactions in chaotic situations. His academic contributions center on filming peers' perverse experiments and pushing boundaries to capture what he considers authentic documentation of human abnormality.
