With large windows adorning its spick-and-span halls, St. Morwald's Home for Children serves as a warm refuge for displaced orphans. For 10-year-old Aya, she is perfectly content living without a normal family, especially since she has everyone at the orphanage wrapped around her finger. However, to her dismay, she is one day selected by a peculiar couple, Bella Yaga and the Mandrake. Aya soon learns that she has, in fact, been adopted by a real witch who wanted her solely as an assistant and had not even considered being her foster mother. As if that was not enough, Aya is told the one rule she must obey at all times—never disturb the Mandrake. To win the hearts of this seemingly heartless witch and the grumpy Mandrake is no easy task; but unlike other children, Aya accepts this challenge without hesitation.
