It puts you on a rooftop watching two girls run their manzai bit, straight man and funny man trading beats, while the building underneath them quietly fills with things that used to be students. Yuu and Nobu's back-and-forth is the actual load-bearing wall here, and it holds. The direction is sharper than a one-shot OVA has any business being, with shot composition that frames the school like a set piece instead of a hallway. Then it turns, hard: get bitten, die, come back, hunt your classmates, and the gore goes further than the runtime earns. Half the people who watch this bail at the first spray and half stay for the dialogue. If you loved how Gakkougurashi weaponized cuteness against you, you already know which half you're in. The comedy pair keeps their rhythm even when there's nobody left to laugh.
Two comedy performers find themselves caught in a nightmare when their school transforms into a hunting ground for something inhuman. Yuu and Nobu are rehearsing their manzai routine on the roof when the building below descends into chaos. A parasitic creature has infested the campus, biting students and transforming them into extensions of itself. The infected become vectors for further infection, turning the school corridors into a labyrinth of danger where survival hinges on recognizing who has already been compromised. Trapped with a handful of other students, Yuu and Nobu must navigate the claustrophobic horror of their own school while keeping their wits sharp enough to stay alive. The comedy duo's chemistry becomes their lifeline as they search for an escape route, but trust becomes impossible when infection spreads silently and the infected disguise themselves among the survivors. This short unleashes supernatural terror in a confined space where every corner could hide a threat and every classmate could be an enemy. It's visceral, claustrophobic horror that treats its premise with genuine menace rather than school-based melodrama.
