For hundreds of years, vampires have lived in secret, hiding their existence from the human world. Among them, the most powerful young vampires attend Crimson Academy, a prestigious school where they learn to control their abilities and prepare for the dangers lurking in the shadows. Katsuki Bakugo is one of the academy's strongest students. Known for his explosive temper and incredible power, he refuses to let anyone challenge his position. His closest friends are Kirishima, Kaminari, and Sero, who somehow always end up getting dragged into trouble with him. Meanwhile, Izuku Midoriya spends his time studying vampire history and ancient legends, while Shoto Todoroki remains distant and mysterious, rarely speaking unless necessary. Everything changes when strange events begin happening around the academy. Students disappear during the night, strange symbols appear on the walls, and rumors spread about an ancient vampire hidden somewhere within the school. While Bakugo insists it's probably nonsense, Midoriya becomes convinced that something dangerous is awakening. As tensions rise, rivalries grow, secrets are revealed, and the group finds themselves pulled into a mystery far bigger than any of them expected. In a world of vampires, trust is fragile, power is everything, and the darkness is always watching.
