My Shapeshifter Girlfriend

[VOLUME 1 COMPLETE!] He transmigrated and fell prey to the divinities the moment he arrived. Even after he reincarnated again into his 3rd life, they came for him and his supposed family, killing the few people he actually gave a real damn about. Finally accepting the Demon Goddess' offer, he ascends to the position of the Demon King. He grew stronger and the Demon Realm grew alongside him. He learnt to make new Devils and forge Devil artifacts, which were supposed to be extinct. Everything was going well but what? "Why didn't you tell me sooner?!" "It was just a suspicion." "Suspicion or not, don't you think that the fact that my girlfriend transmigrated into this world alongside me was something I might want to know?!" --- --- --- --- Update Schedule: Everyday ---- --- ---- Tags: Righteous MC turns Villain and then OP, R18, Kingdom Building, Magic, Tragedy, Transmigration, Action, Level Up, Romance, Action, Nonhuman Lover, Sentient Monsters, Fight Divine Beings ..
