As both Gokudera and Gamma rest for a short time to finish their fight, Gamma reveals he has a deep hatred of Byakuran, believing that he did something to his boss Uni that caused her to become emotionally detached. Meanwhile, Yamamoto finds and fights Byakuran's strongest subordinate, Genkishi. Yamamoto tries to use the knowledge he gained from adult Squalo's fights he watched during his training to defeat Genkishi's illusions, but he is knocked out. At the same moment, Chrome Dokuro, Lambo, I-Pin and Hibari's subordinate, Tetsuya Kusakabe, invade the Millefiore base, while Tsuna and Spanner are attacked by several Millefiore members. Before Yamamoto is finished off, the adult Hibari appears to fight against Genkishi. Although he manages to fight at the same level, Hibari runs out of rings and weapons and is overpowered. As Hibari is about to be killed, he is suddenly replaced by his younger self.
