An overweight and unattractive fujoshi in middle school, Matsui Youko spent the months after graduation undergoing a strict regimen of diet, exercise, and studying fashion. By the time Matsui entered North Haneda High, she quickly gained a reputation for having one of the most dynamite bodies in school, which she flaunts. Intending to bury her past as a fujoshi, Matsui saw Asai Rumi’s unabashed fandom and seeming popularity with men to be a slight on all of her efforts. Though initially Asai’s tormentor, the two quickly came to an understanding, becoming best friends and even fellow collaborators on doujinshi.
Matsui originally discovered BL in junior high thanks to a Shinji x Kaworu doujinshi, and is currently a fan of titles such as Gundam SEED and Fullmetal Prince. Her tastes are similar to Asai’s, though she occasionally prefers pairings in the opposite order. Matsui is also in a relationship with Chiba Shunsuke, a suave blonde whom she had a crush on since junior high, and whom she originally thought was gunning for Asai.
The first time that Matsui and Chiba engage in intercourse, Matsui bases her assumptions of how sex should proceed on her experience with BL material, believing her boyfriend’s capacity for and willingness to receive anal foreplay to be greater than in reality.
