Kaiki Senban! Nekomachi Shoutengai

Summary

At a particular shopping district located in an old Tokyo neighborhood, humans and cats seem to live together in peace. But these cats aren't your ordinary felines! They are spirits, whose human forms allow them to go about their days undetected amongst the other locals. And the truth is, this neighborhood attracts some rather unique problems because of its residents. Chisato, a shop owner and the only human aware of the cat spirits' presence, and Kotora, a young cat spirit band together in attempt to solve the various predicaments they encounter. But will luck be on their side? (Source: Shodensha)
