Doremi believes she's the unluckiest girl alive, what with her battling parents, mocking younger sister, and unrequited crush. She used to daydream about possessing magical powers to improve her luck, but that seems like wishful thinking now. By chance, Doremi crosses paths with a bona fide witch and ends up transforming into an apprentice herself. Sadly, her magical prowess is woefully subpar. Together with her buds, Doremi is tasked with honing her craft to attain the mantle of full-fledged good witch; if only their focus would hold. Passing the witch exams is a formidable feat, one that requires all the serendipity they can muster. Only then can Doremi settle her debt with the tough-loving witch Majorika, otherwise she'll remain a hapless novice with no special abilities.
