A bookish girl with glasses becomes a mystery-solving magical girl, except the magic isn't the point, solving the puzzle is. The transformation is just permission to be clever out loud. This is for kids who read mystery novels instead of watching TV, suddenly seeing themselves reflected back as the hero who uses her brain to save the day.
Hinami is a quiet girl who loves books and hides behind her glasses, content to observe the world from the sidelines. Everything changes when she discovers her secret ability: the power to transform into Nazotoki-hime, a brilliant detective princess who can unravel any mystery with style and wit. Armed with her newfound confidence and detective skills, Hinami steps out of the shadows alongside her two closest friends, ready to tackle the puzzles that surround them. Each case brings something different. A stolen item, a strange rumor, a puzzle that doesn't quite add up. When Hinami transforms, she becomes someone fearless and sharp, someone who doesn't hesitate to speak up and take charge. But the real mystery isn't just solving the crimes around her. It's figuring out who she really is when the transformation ends and the glasses come back on. This is a story about finding courage in unexpected places and discovering that the quiet girl with her nose in a book might be braver than anyone realized.
