Beelzebub-jou no Okinimesu mama.

Synopsis

Pandemonium is a paradise populated by demons who run Pandemonium in Satan's absence. Beelzebub, a former Seraph, now rules Pandemonium and many demons look up to her as she is an expert ruler. However, in private she is ditzy, air-headed and loves anything fluffy. Her head attendant, Mullin finds her asleep, naked and surrounded by fluffy White Gossamers, embarrassing Mullin who finds her cute but infuriating. Beelzebub frequently amuses herself by teasing him. Mullin learns Beelzebub trusts him a lot he is the only attendant she is willing to complain to. Realizing he may have upset her by running away Mullin gives her Alpacca wool sweater, so she can feel fluffiness without sleeping naked. Beelzebub is happy Mullin does not hate her. Beelzebub explains demons do not cause human sin, they provide opportunities to sin or not to sin so God can judge them accurately. One of Beelzebub's duties is to make sure demons living in Pandemonium are content. Mullin worries she may be in danger until he learns she fought in the war against Heaven and was second only to Satan. Despite this Mullin gets angry that she keeps wandering away from him while in town. They argue and Beelzebub ends up getting lost. Mullin beats up two demons harassing her in a bad neighborhood and gets angry at her for worrying him as he kabedons her. As they return home Beelzebub sends Mullin away as his protectiveness of her has confused her and made her heart race. Mullin worries he has overstepped and might lose his job. Beelzebub finally uses her new sweater.
