A girl walks into a convention and falls into a world built from pure fan desire, then watches it collapse in real-time as the event ends. The joke lands because the show understands what anime fans actually want, then treats that want as a physical place that can break. Twenty minutes is exactly long enough to let the absurdity breathe without explaining itself to death.

Rei is heading to a Stratos 4 convention when he stops for a bathroom break and instead lands in the Yukikaze world. There, Maeve, Super Sylph, Sylphide, One-chan and Two-chan are fighting for survival. The place was born from the wishes of anime fans and lasts only while they keep their favorite characters in mind. With the convention drawing to a close, this world starts to fall apart, and Rei has no idea how to return home. The single OVA plays this science fiction premise for comedy.
