It's about this 2 wandering priest (or exorcist). One of them has black hair, and the other has light hair.
The black hair exorcist likes (romantically) the light hair guy. It is shounen ai or maybe yaoi. But it's definitely adventure. Also I remember that there was a chapter that showed when they were little, and I remember the black haired priest was like using this doll and nailing it to the tree to curse someone who went near the light haired priest and he got called out by another priest (older). Sorry if it's kinda vague. I would appreciate any help =D
