A teacher at the protagonist's school with a license in healthcare...in other words, she's the school nurse. She is one of the few women at the all-boys' school, and her calm and gentle personality makes her very popular. This makes her the object of everyone's admiration on the surface, but in her private life, she is a total failure. She is a good-for-nothing older sister lacking in feminine energy, but she greatly excels in making others spoil her. Even today, she spends her time lazily relying on her beloved Na-kun (her nickname for the protagonist).

A foreigner studying abroad in Japan as a newly-appointed English teacher. Her honest and transparent character allows her to disregard the relationship of student and teacher and make friends with anyone. Due to a certain incident, she falls in love with Narumi at first sight and, as a show of how unpredictable she is, immediately starts engaging in sexual relations with him. She is admittedly lecherous, but not vulgar or lewd, and only engages in such activities with those she is comfortable with. This high-octane girl is the reason Mitama and Aya are spurred into action.
