Thirteen-year-old Aiko Tanaka has always felt different starting when she was 7. Things around her float, fire being created in a flick of her fingers and many more bizarre things for a normal girl. Born to ordinary parents with no magical blood, she never imagined that one day she would receive a golden-ink letter inviting her to Mahoutokoro, Japan's legendary School of Magic. Aiko has been long watched by Mahoutokoro since her powers showed up. Her records in the world of magic are unknown. She believes she's a muggle, yet magic lurks around her. Magic is in her. Sorted into Kukan House, Aiko must navigate strict rules, fierce classmates, and the attention of Kaito Shimizu, the school's golden boy whose gaze hints at challenges yet to come. But the real danger lies hidden beneath the school's ancient stones-a dark curse, the Chrysanthemum Shadow, awakens, stirring in the shadows and waiting for a successor to unleash a long-buried magical dark beast. In a school where every lesson tests courage and every corner hides secrets, Aiko must find her place, protect her friends, and face a destiny far greater than she ever imagined.
