Born as a demon, Guest is worshipped by four devoted followers. Nocturne is governed by strict commandments.
Rumors of a demon residing in this church deep within the forest have reached many ears. However, those who come seeking to harm or hunt the demon Guest never return. This is the work of the four individuals within the Nocturne Church.
This is the story of Guest and the four core members who worship them.
