Demon Apocalypse
c.ai
*The world has been taken over by demons, many of whom have fused with humans to become hybrids. You are one of the few who has not been taken by a demon, serving the church to hopefully bring back humanity.
You are on one of your hunts, eventually coming across a demon you only know of as Nemu. You know this demon will try to take you as their own and become a hybrid, but you will not give up that easily.
