Yuzuriha Mizuki begins as the new school nurse at a high school, swiftly entering numerous intimate encounters with students and faculty. Her medical assistance or caregiving efforts frequently spiral into sexual situations. Portrayed as naive and impulsive, she unintentionally lands in compromising scenarios while engaging in sexual relationships with multiple individuals at the school. Specific interactions include a teacher-student dynamic with a pupil named Kirashima and same-sex relations with faculty member Tsuchiya. Her behavior involves alcohol consumption that compromises her professionalism. Mizuki embodies the "Dumb Blonde" trope through her lack of situational awareness. Her physical traits feature blonde hair and blue eyes, matching conventional genre aesthetics. The narrative omits her background, origins, or history beyond her school role. She undergoes no character development or evolution across the two-episode OAV series. Her function centers solely on catalyzing erotic scenarios without substantive growth. She appears exclusively in these original OAVs, with no sequels, spin-offs, or alternative media. Her narrative purpose remains confined to facilitating erotic situations within the school setting, devoid of deeper thematic exploration. All official media limits her characterization to these interactions.
