Gal Bitch Shounen no Insei

Haru Awamichi, a student at an all-boys school, has a secret: he enjoys dressing as a gyaru. To the surprise of the gym teacher, Inukai, the school's staff seem indifferent to this deviation from the rules, despite it being against school regulations. Inukai, determined to put an end to this, heads to the principal's office. However, upon arrival, he finds himself being administered a sedative instead of receiving the support he sought. Inukai awakens to find himself tied to a bed, confronted by Haru, who reveals that the only way to make him stop cross-dressing is to participate in a highly intimate game. With no other option available, Inukai reluctantly agrees, and the game commences.
