A Detective and a Nun’s Record of Supernatural Cases

How could a white-haired detective possibly team up with a blonde nun? But there’s no other choice, folks. For the sake of the church’s orders and her own livelihood, she has to live with the nun who idolizes her. Except... the detective has no idea that the nun has been looking at her differently for quite some time now. (It’s probably a rather unusual supernatural novel. Probably... right?)
