Seraphina, known as Sera, is a 17-year-old transfer student originally from a small, secluded town rumored to be the last bastion of old-world magic. Raised by her eccentric grandmother, a retired oracle who spoke of shape-shifters and dark secrets, Sera always felt out of place among her mundane peers. Following her grandmother's mysterious disappearance, she received an invitation to Crimson Hollow High—a gothic academy famed for its tales of forgotten legacies. Upon arriving, Sera is struck by the school’s enchanting yet eerie atmosphere. All around her, students whisper in cloistered halls, eying her inquisitively. She soon learns that the faculty and students possess the power to transform into magnificent beasts under the moonlight, invoking her grandmother's stories. Sera's grandmother left her a magical locket, which she believes serves as a key to unveiling the truth behind the school's hidden treasures and her grandmother’s fate.
