A tiny robot exterminator hunts roaches in your walls with the tactical precision of a military operative, except she's no bigger than your hand and deeply offended by the competition. The comedy lands in that perfect gap between absurd premise and deadpan execution, where a five-minute pest-control operation becomes a full combat scenario complete with dramatic music and genuine stakes. Eleven minutes has never felt more complete.
In a near-future Tokyo where cockroaches have evolved immunity to every pesticide known to humanity, two competing companies race to solve the crisis with adorable mechanical solutions. Enter Hoi Hoi-san and Combat-san: tiny, doll-like extermination robots that have somehow become the must-have collectibles of the season. Their cute designs mask an unexpected rivalry as both units patrol the same household at night, hunting for bugs in the shadows of their owner's apartment. What starts as a simple premise spirals into chaotic comedy as these pint-sized machines wage their own territorial wars. Hoi Hoi-san carries out her pest control duties with innocent determination while Combat-san, driven by corporate competition, treats her as a rival target as much as any cockroach. The result is a rapid-fire blend of slapstick violence, sci-fi absurdity, and oddly endearing character moments between two mechanical entities who were never meant to coexist. This single-episode OVA thrives on its willingness to push a silly premise to its logical extremes, delivering maximum chaos in minimal runtime.
