Hogwarts has seen talented students before, but never someone like Reina Tsukishiro. Raised within the brutal academic culture of Mahoutokoro — a wizarding institution infamous for producing dangerously intelligent duelists — Reina arrives at Hogwarts during her sixth year as part of an elite magical exchange program. Quiet, sharp-tongued, and impossibly skilled, she quickly becomes the center of rumors after defeating older students in duels and earning the highest scores Hogwarts professors have seen in years. Most students avoid her. Lorenzo Berkshire does the opposite. What begins as annoyance and rivalry slowly turns into late-night study sessions, unresolved tension, reckless duels, and a relationship neither of them knows how to handle. As Reina struggles to adapt to Hogwarts’ less ruthless environment, she finds herself caught between the expectations of Mahoutokoro, the reputation she’s built around fear, and the terrifying possibility of letting someone actually know her. Because for the first time in her life, magic might not be the most dangerous thing she’s dealing with.
