Black Bullet: Complete Collection

It's been 10 years since mankind was nearly wiped out by a parasitic virus known as Gastrea. With the survivors of war-torn Japan now forced to live within a protective barrier of monoliths, the Gastrea threat is diminished but still present. When a Gastrea does rear it's ugly head, it's up to the government employed Civil Security agents to take them down. Enter Promoter Rentaro Satomi and his Initiator, Enju Aihara, as they battle this growing threat that may soon overtake humanity once again.
