Okyaku-sama wa Kamisama Desu.

A deity appears as a customer, but these modern gods are violent monster claimers causing chaos. Shurara and Shiratsuka, an unfortunate pair, deal with these overwhelming divine customers at a convenience store. Located in the underworld, the store is filled with strange and unfortunate occurrences. Shurara works in customer service to pay off her parents' debt and ends up at Neko Market, a magical convenience store. There, they face various disruptive entities including delinquent monster claimers, Virgin Mary, a child prodigy, a wind god, a thunder god, and yokai beyond human comprehension.
