Beelzebub-jou no Okinimesu mama.

One of the seven princes of Hell, Beelzebub, is said to have betrayed God and been exiled from Heaven forever. All previous angels now reside in the kingdom of Pandemonium, which is ruled by Beelzebub, and labor there every day of their eternal existence. If Beelzebub were a devil, people would shudder at the mere mention of his name. But what if Beelzebub is not as bad as once believed? What if he had a fluffy object obsession? What if Beelzebub is a female after all? When Myurin is employed to work for Her Majesty Beelzebub, he finds that out. She may know exactly what needs to be done to keep Pandemonium operating smoothly, but once she leaves the formality of the workplace, the girl requires some help in order to act like a typical... devil. Myurin is secretly infatuated with her adorable antics despite the fact that he detests acting impolitely. His new job has also taught him that nothing is as it seems, particularly when it comes to the other chief demons of Pandemonium.
