Belzebeaut

Beaut was accidentally summoned by Mayuri after she decided to summon a demon because she stained her skirt. At first he's outraged at this simple request and the meager fee she has to offer, until he is distracted by the smell of her freshly-baked sweets. Mayuri uses this weakness to have him do her bidding, while in reward giving him her own baked goods. Beaut obviously doesn't understand human emotions very well, and acts irrationally, usually causing Mayuri to be upset, even though he cares for her.
