Episodes
The Last Hope
Year 2031: Tokyo Area. Most of the human race has been wiped out by the parasitic Gastrea. Part of the Anti-Gastrea movement, high school student Satomi Rentaro works as a civil officer for Tendo Civil Securities. On a mission, he meets a suspicious man in a mask and a tuxedo: Hiruko Kagetane.
The Mask of Madness
Rentaro and President Kisara head to the Defense Ministry after being summoned. All of the reputable civil officers from the Tokyo Area show up there. The one who summoned them there is Seitenshi, in regards to destroying the host Gastrea and recovering the contents of the case that's inside the Gastrea.
The Children of Fate
Enju is treated like an outcast at her school when it is found out that she is one of the Cursed Children, who have the Gastrea virus within them. Despite her sadness, they go look for the host Gastrea. She gives it her all and instantly is able to recover the case...
Black Bullet
Hiruko instantly takes care of 29 civil officer pairs and comes face to face with Rentaro and Enju again. Rentaro shows his true power to Hiruko, proving that he's not the only one that was part of the New Human Creation Project and they battle again.
The Crimson Black Assassin
The Tendo Civil Security Agency gets a job from Seitenshi. The job is to act as her bodyguard. Rentaro isn't very fond of the idea, but notices odd activity when it's revealed that Seitenshi will be meeting with the head of the Osaka Area while Kikunojo is gone.
Tragic Irony
Seitenshi's vehicle is hit by a sniper while she in enroute to her meeting. Rentaro realizes this is more than a mere assassination attempt and gets help from Miori to find out more about the attack.
In the Still of the Moonlit Night, the Dawn Sky
Rentaro gets hurt trying to protect Seitenshi from the sniper. The security plan that Seitenshi's bodyguards had set up were leaked to the sniper. Enju had gone after the sniper and falls into a coma.
The Monument on the Border
Rentaro had set up an outdoor classroom for the kids in the outer district and was enjoying class. Seitenshi suddenly appears and lets him know that one of the Monoliths is about to be destroyed.
The Protectors of the Barrier
The monolith finally starts to turn white. In fear of the great destruction to follow, the people of the Tokyo Area start panicking. Meanwhile, the civil officers start gathering around Monolith 32.
Tokyo Area Defensive Battle
Before the battle against Aldebaran, Rentaro and Enju enjoy the outdoor class with the girls of the Outer District. Because the girls have very little hope and are unsure of their future, Rentaro takes them to a place where humanity had won their last battle against the Gastrea. Only three days remain until the destruction of the Monolith.
The Heart of Taurus, the Spear of Light
The outdoor classroom is completely destroyed because of the bombing. Hope is starting to be destroyed along with the Monolith as the JASDF and Gastrea face off. However, the ones to show up at the civil officers' base were JASDF who had been turned into Gastrea themselves.
Crisis Point
Rentaro is condemned for a decision he made in battle, and is told that there is another Gastrea named Pleiades that is protecting the already supposedly immortal Aldebaran. Rentaro is forced to face the enemy alone, and is helped by someone rather unexpected: his enemy from the past.
The Ones Who Aspired to Be Gods
With the addition of Kagetane and Kohina, the adjuvant is complete. They choose the Flames of Revolution, the last place humanity won their battle against the Gastrea, as the ground for the final battle against Aldebaran.
