Strike the Blood

Kojou Akatsuki was just a normal high schooler living in Itogami Island's Demon District-until a chance encounter turned him into a vampire. Now, he's learned he's no ordinary bloodsucker but the fabled fourth primogenitor, a being of legendary power. Concerned by his potential danger, the Lion King Organization assigns Yukina Himeragi, a young sword-shaman in training, to watch him. Her mission: observe Kojou, and if necessary, eliminate him. Thrown together, the two reluctantly join forces as Kojou grapples with his newfound abilities and they work to fend off the growing threats to their city.
