Nobody's heard of this one because it's a single OVA dropped in 2012 with almost no fanfare. What you get in that one episode is pure comedy chemistry between a broke shrine maiden and a cat deity who shows up to ruin her life in the most specific ways possible. The humor doesn't reach for broad appeal; it trusts you to find the joke in the smallest interactions, the timing, the way these two characters orbit each other's disasters. If you've ever wanted a show that treats a supernatural premise as an excuse for character comedy rather than spectacle, this 25 minutes knows exactly what it's doing.
A cheerful cat deity and her motley crew of shrine inhabitants take on an unexpected job during cherry blossom season: ghostbusting. What starts as a simple request to clear spirits from the local festival grounds spirals into comedic chaos when the group discovers the ghosts aren't interested in leaving. Between Mayu's lazy attitude toward actual deity work, her human companion's exasperation, and the various supernatural beings who keep getting in the way, the operation becomes less professional extermination and more controlled disaster. The tone balances slapstick humor with the cozy supernatural atmosphere of the main series, treating its ghostbusting adventure more as an excuse for character hijinks than serious action. Viewers who enjoy comedy rooted in character quirks and supernatural settings without high stakes will find plenty to laugh at here. This is comfort-food anime that knows exactly what it is: a brief, silly detour into the world of a cat god who'd really rather be napping.
