Black Bullet ♥♥♥♥ Huge insect-like monsters called Gastrea devastated the world 10 years ago. At that time, rare girls were born with the Gastrea virus, possessing immense fighting skills. Civil Services were formed and paired an Initiator (infected child) with a Promotor (combat skilled human to lead the child). Rentarō, a unique Promotor, and his Initator, Enju, fight to save Tokyo. Though most of Tokyo views them as no better than the monsters they fight.
