But despite his fearsome reputation, Diablo’s true identity is Takuma Sakamoto, a shut-in gamer devoid of any social skills. Defeating hopeless challengers day by day, Takuma cares about nothing else but his virtual life—that is, until a summoning spell suddenly transports him to another world where he has Diablo’s appearance!In this new world resembling his favorite game, Takuma is greeted by the two girls who summoned him. They perform an Enslavement Ritual in an attempt to subjugate him, but the spell backfires and causes them to become his slaves instead. With the situation now becoming more awkward than ever, Takuma decides to accompany the girls in finding a way to unbind their contract while learning to adapt to his new existence as the menacing Demon King.

It was one of those anime(s) with MC being the strongest but with a lot better story and comedy. Fan Service was a little too much though like always. I would definitely recommend this anime to any isekai fan also hoping for another season.


I always rejects anime that have anything sexual, like big boobs, all about boobs and his face in her boobs and also showing panties. But I liked Demon Lord and how the story goes, it was entertaining but I was expecting more, like SAO (But not as good as SAO).


I'm sick of over the top fanservice in anime. It's not like it has a ton of episodes so I thought there was way too much time spent on crap. There might be a good story somewhere in there but the show lost me at episode 2. I'm older and have less patience for its kind. Not my cup of tea. If it is yours, I hope you enjoy it.
