Maou no Kuse ni Namaiki da! 2 ~Kondo wa Seisen da!~

This is the sequel to 'Don't Get Cocky, Demon King!' Thirty-year-old NEET Kuranosuke unified the demon world but didn't become the great demon lord. He lives peacefully with the demon lords in the human realm until one day an angel barges into his room through his monitor again, pulling him into a conflict between two heavenly factions—one bent on destroying the demon world, the other advocating peace. With the help of the demon lords, he resolves the crisis. But then the leaders of both angel factions, along with the earlier angel, move into his house!? It seems they've taken a liking to him after his help. From Hau~ Omochikaeri!
