Cheloaf-san no Mahou Ningyou

This is a slightly different world. Normal humans exist, but so do magics and monsters. The witch Cheloaf’s specialty is making magical medicines, to the extent that many people travel from far away to buy them. Cheloaf’s servant Lololojio is a time-worn doll. When she was little, Cheloaf wanted a friend, so she made the magical doll — and now that she’s all grown up, he spends his days serving her. Source: MU
