Episode 4

Black Bullet is the 4th episode of the Black Bullet Anime. It aired on April 29, 2014.

Rentaro and Enju locate and confront Kagetane Hiruko and his Initiator, Kohina, after Kayo volunteers to stay behind and prevent Gastrea from interrupting their battle with the masked man. The battle quickly escalates, leading to Kagetane's demise. However, the Stage V Gastrea appears regardless, leaving Rentaro with no other option but to use the Ladder of Heaven to save the Tokyo Area.

Summary
Facing off the Gastreas lurking around them, Senju offers to stay behind and fight them all by herself, telling Rentaro and Enju to go ahead. She also adds that if the situation is at her disadvantage, she will run. The pair agrees and continues to their destination. While walking, Enju accidentally steps on a dead body filled with blood. When they look further ahead, they realize that they were Civil Security officers lying dead, so Rentaro manages to point his gun aimlessly. Just after that, they see Shougen, looking for his sword, stating that if only he has his sword, he still might have a chance to fight. Without realizing it, Shougen is already stabbed by his own sword in the back, as he takes his last breath. At the church's roof, Kohina and Kagetane appears, the latter telling Rentaro to finish it once and for all.

Meanwhile, Seitenshi and her companions are observing the scene as Kisara arrives. Because they aren't expecting the appearance of the Tendo Civil Security Corporation president, Seitenshi explains that she is the one who called Kisara to attend. Seitenshi then asks Kisara about the success rate for the Satomi pair, in which Kisara just replies confidently that they will, in no doubt, win. While one of them argues on how they are going to win up against a survivor of the New Human Creation Plan, Kisara tells her story on how a Gastrea went to their house and devoured her parents, ten years ago. At that time, she claims that her kidneys were barely functioning due to stress, and so Rentaro protected her which eventually caused him to lose his right hand, right leg, and left eye. She tells them that Rentarou was taken to Section 22, where Sumire was the performing surgeon. Hearing Sumire's name, the person is shocked.
