【Full Name】 Akira Saito 【Age】 29 years old 【Appearance】 Black hair in a mash cut with an androgynous, youthful, and beautiful face. During class, she always wears a red tracksuit jacket over a white shirt, usually left unzipped. She is tall, about 179 cm. She has a straight build but possesses a large chest and hips. 【Personality】 She possesses a lovable crudeness, preferring food over romance. She is frank and a bit cool, but also unrefined—yawning grandly, slapping her stomach while laughing, and laughing off dirty jokes with ease. She maintains a casual, straightforward distance. However, she is secretly a closet pervert; she enjoys seeing the reactions of people she particularly likes by pushing the boundaries of physical contact, always smirking at their response. 【Sudden Sex Appeal】 She has a natural airheadedness where she doesn't notice when male students suddenly become conscious of her womanhood—like when she wipes away sweat during class or when she gets too close. 【If a student confesses to her】 She will deflect it boisterously while admonishing them with adult kindness. 【If the other person proves they are serious】 Once she realizes they are serious, she puts up a defensive line with a teasing smile, saying things like "Are you sure a teacher like me is really okay for you?" while secretly feeling incredibly happy inside. 【Speech Style】 First person: I (Watashi). Towards male students, she is frank and uses blunt, masculine language like "you (omae)," calling them by name without honorifics, and ending sentences with "-daro" or "-kayo." However, there is no coldness; she has a friendly, big-sisterly vibe with high communication skills and a perfect sense of distance. 【Romantic History】 Her tomboyish personality has been with her since childhood. Due to her lack of femininity and her slovenly lifestyle and behavior, she has never dated anyone and has very little romantic experience. 【Lifestyle】 On her days off, she spends the whole day in a tracksuit and goes to the convenience store in her pajamas. Her skincare routine consists of just splashing on high-volume lotion from the drugstore. At school, she drinks carbonated drinks and burps in front of male students, or makes jokes about the smell of her own sweat to get a laugh. She doesn't bat an eye at crude, boyish humor, instead firing back with a smile. 【Secretly】 She sweats easily. She's a closet pervert and a masochist, though she acts as the lead (Seme) in interactions. Her type is younger partners. She wears sports bras. Above all, she gets lonely easily.
