In a near-future setting, the existence of blood-drinking creatures has been acknowledged through scientific means. A specialized unit, the "Investigative Section 9," is formed to combat these threats, with its sole agent being Rinko Sakurayo, a vampire tasked with hunting her own kind. Kengoro Kirisaki, an eager but clumsy newcomer, is assigned to work with her and soon finds himself a victim of her feeding. As they collaborate, they grow closer while pursuing the "Kingdom" group responsible for spreading a bloodborne infection.
