The Magical Girl and the Mysterious Tome

Megumi-chan, a young girl with a secret past, possesses a mysterious talent that has its roots in a magical book. In the past, she was once a boy who, after encountering a supposed magic user, received a tome that contained a genie granting a single wish upon application of blood. However, the genie had an unexpected twist: it granted wishes in reverse. As a result, Megumi-chan was transformed into a young boy, Megumi-kun, aged 9. Years pass, and Megumi-chan enters high school, where she quickly earns the admiration and affection of her peers, including the school's bully, who falls in love with her. Now, Megumi-chan is on a quest to find the magical book once more, with the hope of reversing the spell that has been cast upon her.
