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 attends what seems like a normal anime convention until reality warps around her, pulling her into a pocket dimension born from the collective fantasies of thousands of fans. She finds herself trapped in a world where fan-created characters and scenarios run wild, where logic bends to match whatever people desperately want to see. The problem: as the convention winds down and fans start heading home, the world begins to unravel. The collective desire that held it together is fading, and Rei has no idea how to escape before everything collapses completely. Caught between fan service gone literal and genuine panic, the story plays this premise for pure comedy chaos. Mave-chan, a combat fairy girl summoned from fan imagination itself, becomes Rei's unlikely ally in navigating this surreal landscape. The tone shifts between absurdist humor and genuine stakes as the countdown continues. If you find comedy in the collision between fandom culture and reality, or enjoy stories where the rules of existence itself are negotiable, this rapid-fire OVA delivers exactly that kind of weird, self-aware fun.
