High school was supposed to be an adventure for Suzuki Ouji, but he never anticipated meeting Kuromori Kisaki, a witch from a 400-year-old clan. During their encounter, Kuromori lost her brooch, which was necessary for flying on her broom. Though hesitant to interact with a witch at first, Suzuki eventually returns the brooch and is rewarded with a demonstration of Kuromori's flying magic. Intrigued by the prospect of flying himself, Suzuki puts on the brooch and they take off into the sky, but ultimately crash into the school's swimming pool. Suzuki is left contemplating the consequences of his new-found abilities and wondering just what he's turning into.
