The female teacher, a colleague of the protagonist at their high school, first regards his extreme susceptibility to fatal accidents with scientific curiosity and measured concern—noting, for instance, his fearful reaction to steam from a humidifier. Her initial shock evolves into routine acceptance, and she begins treating his repeated demises with morbid humor, joking with staff and anticipating these incidents as grimly predictable events. Their professional rapport features camaraderie, regularly socializing during lunches and discussing everyday challenges.

When the protagonist endures an unusually long period without dying, she reveals his past willingness to risk death for students unexpectedly inspired her own teaching methods. Motivated by this perceived dedication, she actively urges him to resume perilous behaviors to reignite her professional drive, underscoring her dependence on his example.

Her practicality surfaces when a delinquent targets the protagonist: she intervenes to warn that even minor contact could prove fatal, primarily to prevent unintentional murder charges. Her observational nature further emerges upon witnessing him display unexpected strength—like stopping a truck to save a puppy—where she later notes his diminished extra lives but focuses on implications over admiration.

Throughout, she maintains professionalism while normalizing his condition, engaging in matter-of-fact discussions about near-death incidents without overt emotion. Her grounded presence balances concern and adaptability, serving as a stabilizing counterpoint within the school.
