Shino, a strikingly beautiful chemistry teacher at Shirakumo Academy, commands considerable attention within the school environment, particularly noted for her distinctive glasses. Her educational approach transcends conventional academics; when student Sayaka Iijima voices anxieties about sexual relationships, Shino provides direct guidance, covering contraception and demonstrating sexual acts through practical participation. This reflects her non-judgmental, open-minded attitude toward students' personal concerns, though her methods extend beyond typical educational boundaries. Her interactions include addressing delinquency: after confronting three male students engaged in extortion, she prioritizes their truancy over misconduct, emphasizing academic attendance. When these students later visit her residence with coercive intent, Shino's prior arousal shifts the encounter to consensual territory. The following day, she critiques one student's inadequate sexual performance and offers hands-on correction, framing it as essential for his social development. This reinforces her belief in practical sexual education as behavioral reform, resulting in the student expressing gratitude and committing to self-improvement.
