A teenage boy trapped in an all-girls school has to nail the performance of his life just to survive the day. The comedy doesn't come from the premise sitting there looking cute, it comes from watching him actively fail at the basics, panicking every time someone gets close, sweating through makeup tutorials. This is peak early-90s ecchi chaos where the joke is the desperation, not the setup.

Banji's status-conscious parents want him at a good school, but they will not pay for a good co-ed one, so the teenage pervert ends up as the only boy at an all-girls school. To stay enrolled, nobody can learn he is a guy. Alongside math and science, he now has to master bras and makeup. Stuck at the very bottom of the social pecking order, Banji must hide his masculinity from the pretty classmate who has won his heart while dodging female bullies who threaten to expose him in the locker room. The single OVA plays this cross-dressing premise for comedy and ecchi gags.
