The 30-year old NEET Kuranosuke unified the demon world, but didn’t end up being the great maou. He lives peacefully with the maous in the human world, but one day an angel came to his room (via his monitor again) and he ended up being caught in a strife between two heavenly powers, one intent on destroying the demon world and the other with a pacifist approach. Somehow, he was able to solve it with the help of the maous. But then the two angel faction leaders, as well as the angel from before, came to stay at his house too!? It seems like they’ve taken a liking to him after his help from before.
