Black Bullet

Gastrea, a parasitic virus that has destroyed humanity, has imprisoned humanity inside a wall built of Varanium Monoliths, a metal with the power to control Gastrea. The "Cursed Children," infants with the Gastrea virus who can control it and possess superhuman skills, were soon identified. The Gastrea virus's influence made it possible for the Cursed Children to only be female. Civil Securities are created to specialize in defeating Gastrea, and they work alongside a pair of Initiators, who are cursed children, and a Promoter, who serves to guide the cursed children. Ten years after the war, Rentar Satomi, a high school student who serves as a Promoter in Kisara Tend's Tend Civil Security with his Initiator Enju Aihara, is given a secret mission to stop the devastation of the Tokyo Area.
