Sensei operates a medical clinic sharing a building with the S&A Detective Agency. His clinic routinely treats the agency's members and their associates. He displays overtly lecherous tendencies, especially directed at his assistant Monica, whom he frequently photographs in cosplay attire. His personal motto champions lust as a fundamental human drive.

Despite these perverse inclinations, Sensei maintains professional competence as a doctor. His clinic functions as the primary medical facility for injuries sustained by main characters during investigations, particularly those involving Sara's protection. His medical skills are functionally relevant to the central plot, especially concerning cases tied to the Glass Maiden phenomena.

His assistant Monica actively participates in his interests, accommodating the cosplay photography and inappropriate physical contact, suggesting a consensual dynamic within their working relationship. This dynamic occasionally intersects with the detective agency's activities, primarily for comic relief.
