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 where cockroaches and other household pests shrug off every insecticide, a Japanese company answers the crisis with Hoi Hoi-san, a tiny doll-like robot built to wipe out bugs. A rival firm soon releases its own model, Combat-san. Thanks to their cute looks, both machines have become a craze with a devoted following. Late at night in a fan's home, the two little robots go hunting for insects, but Combat-san is just as happy to take a shot at Hoi Hoi-san along the way. The single-episode OVA mixes comedy, sci-fi and slice of life around a squabble between two pint-sized exterminators.
