After betraying God, Beelzebub, one of the seven princes of Hell, was banished from Heaven for all eternity. She now reigns over the kingdom of Pandemonium, where former angels toil for their immortal lives. Even the mere mention of her name sends shivers down people's spines due to her fearsome reputation. But what if Beelzebub isn't as monstrous as people believe? What if her passion lies in fluffy things, and she's actually a woman? This is precisely what Myurin, Beelzebub's new assistant, discovers when he joins her team. Despite her competence in running Pandemonium, Beelzebub needs help in appearing like any other devil outside her office. While Myurin finds it challenging to steer away from professionalism, he can't help but be drawn to her endearing quirks. His job opens his eyes to the fact that first impressions aren't everything, especially when it comes to the other powerful devils in Pandemonium.
