This is a world where witches and humans coexist. In order to ensure that the identity of the witch is not exposed, the witch whose true identity is discovered by humans will turn into a witch frog. Only another witch with an official identity can unlock the magic. By chance, the girl Harukaze Doremi (voiced by Chiba Chiemi), who has always dreamed of becoming a witch, discovered the identity of the witch Lika. In desperation, Lika had to accept Harukaze as an apprentice witch. Harukaze must go through a long and arduous training and pass the witch's exam to officially obtain the qualification of a witch. After that, the mature and quiet Fujiwara Yuzuki (voiced by Akitani Tomoko), the smart, capable and lively Meio Aiko (voiced by Matsuoka Yuki), the arrogant and domineering but kind-hearted Segawa Odo (voiced by Shishido Rumi), Harukaze's sister Harukaze Paopao (voiced by Otani Ikue) and others all became apprentice witches one after another because they discovered Harukaze's identity. As time goes by, passing the witch exam has become a secondary goal for the girls. The most important thing is to use their magical abilities to make people happy.
