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.
Mayu is a cat god who lost her rank and powers and was banished from Takamagahara to Earth for illegal gambling. She now lives with a girl named Yuzu in Yaoyorozudou, an antique shop. When Yuzu proposes a day of cherry blossom viewing, Gonta, still smitten with her, promises to find the finest spot. Finding an empty place on a fine Sunday is hard, but Shirasaki Hasumi recalls a blooming cherry tree in the yard of an abandoned hospital. The catch is that a mischievous ghost girl has possessed the tree. The result is a single comedic OVA with supernatural touches, released in 2012.
