Harukaze Doremi considers herself the unluckiest girl in the world. Her parents are constantly fighting, her younger sister teases her, and her crush is infatuated with another girl. If only Doremi could simply wave a magic wand, she would have a much better life—or so she used to think. After a mishap involving a real witch, Doremi becomes an apprentice witch herself, and it turns out she is pretty horrible at that, too. Now she and her two friends must study to improve their magic skills so they can become good witches. That is, if they can focus on their magical studies! The three apprentices will need all the luck they can get if they want to pass the witch exams and become full-fledged witches. Only then will Doremi's debt to the witch Majorika be repaid. Until then, Doremi will remain a useless little witch girl!
