Kojou Akatsuki

Kojou Akatsuki was an ordinary high school student until a mysterious encounter with Avrora transformed him into the legendary Fourth Primogenitor. While he deals with uncontrollable vampire instincts and physical side effects like nosebleeds, he possesses unparalleled superhuman strength and speed. He serves as the vessel for twelve powerful familiars, granting him a level of magical potential that defies logic. Despite having no memory of the incident that changed his life, he now lives as a supernatural entity.
