Volume 5

Summary
At the Scar Chain hideout Rokuro, alongside his foot soldiers, holds everyone hostage and attempts to publicly execute the Deadmen in order to force Nagi into joining the Undertakers. He orders Mōzuri and Shinagawa to kill Ganta right before Senji bursts in, killing them both instantly. The other Deadmen break free of their hold and manage to defeat the remaining Undertakers alongside Senji, who uses Invisible Black, a supersonic version of his Branch of Sin, to counter the worm eaters. While waiting impatiently Scar Chain's public execution, which was prevented, Genkaku recalls Nagi's forgotten tragic past in order to bring out his insanity. At the mean time, Senji rejects Karako's proposal to join Scar Chain, saying that the outside world isn't different from the prison. Before departing, Senji tells them they shouldn't act almighty if they cannot do it themselves. After witnessing the death of his friends once more and lacking the power to protect them, Ganta goes in search of Senji's help in order to improve his abilities and learn the supersonic version of his BoS. Senji gladly accepts as they start their training session. At the same time somewhere in Deadman Wonderland, Shiro, while crying over Ganta's rejection, meets Toto Sakigami, who refers to her as The Wretched Egg.

With little to no success in their training, Senji crushes Ganta's medicine candy in order to boost his self-confidence and determination. He hangs the final one on a thread, saying that he can have it back if he manages to surpass his Invisible Black and shoot it down. While Toto attempts to distance Shiro from Ganta, she accidentally eats liquor candy while drowning her sadness in sweets and works up the desire to go and punch Ganta for his behavior towards her. As she leaves, Toto comments that he should go and eat some sweet Branches of Sin. Due to the lack in numbers and the much needed strength, Karako decides to abandon Nagi. After getting the necessary information from Rokuro, she instructs everyone to take a separate route in order to escape with each member having their own copy of the data chip. After everyone leaves, she decides to turn her back on the plan and attempt to save Nagi herself, disguised as one of the foot soldiers. While the inspection team is being entertained with a prisoners concert, Tamaki orders Genkaku to annihilate the remaining Scar Chain rebels. In the mean time, Karako attempts to infiltrate Undertaker HQ, when Shiro bursts through the air duct in a drunken state, searching for Ganta. Genkaku sees through her disguise and takes them both hostage. Back at the gym, Ganta barely manages to form a supersonic blood bullet due to anemia and shoots down the candy, but before he can celebrate Genkaku makes a live broadcast to all Scar Chain members in order to provoke them into attempting to rescue Karako and Shiro before they get molested. As Ganta flees the gym, he runs into other Scan Chain members who've decided to rescue them. When they arrive at the Undertaker HQ, Genkaku greets them right before commencing with their final standoff.

Before the battle unfolds, Hibana breaks Shiro's legs in order to stop her from interfering. The battle starts as the Deadmen clash with the Undertakers.
