Detesting his weak self, Ganta asks Senji to teach him how to use his Branch of Sin to fight. Meanwhile, Karako attempts to infiltrate the Undertakers by disguising herself as a guard. As Toto appears before Ganta and Senji during their training session, Shiro, who gets drunk off of liquor sweets, appears before Genkaku, who also discovers Karako. Just as Ganta manages to produce a blood bullet that can break the sound barrier, Genkaku announces his capturing of Shiro and Karako. Despite being low on blood, Ganta rushes to where Genkaku is keeping them, but is confronted by Nagi, who had been mentally broken by Genkaku and turned into a raging demon.
