Heroines, I'm Really not the Devourer Novel

Once known as the Bloody Devil, Linfer's catastrophic power nearly destroyed humanity until his arrogance attracted the attention of the universe's ruling force. Stripped of his position and cast backward through time, his soul now inhabits the Devourer—a creature of legend feared to consume the will of destiny's chosen. Yet this infamous monster is pathetically weak compared to the mythical beasts of this primordial world. To survive, Linfer must embrace a new path: seduction and the building of a devoted harem, allowing him to tame this vile Devourer and reclaim his dominance.
