Kakashi is faced by Kigiri, who uses his Exploding Flame Shot to ignite Kakashi and then bind him with his Binding Smoke Prison.

Naruto tells her that even if Yūkimaru despises her, she must be there for him and protect him, which she agrees with. On the clifftop, Yūkimaru runs out of chakra and is unable to control the Three-Tails, prompting Rinji to attempt to inject him with Orochimaru's Juinjutsu to grant him the chakra needed. His attempt is blocked by Guren and Naruto, who arrive in time to save Yūkimaru. Faced with no other choice, Rinji tells Yūkimaru that Guren was the one who killed his mother and took away his home and that he should have his revenge by using the Three-Tails to kill her and destroy Konoha. However, Yūkimaru tells Guren that he forgives her and that he loves her; Guren responds that she loves him too and that she will always be with him, thankful that he has chosen to forgive her.

"Rinji" then peels his face off, revealing himself to be none other than Kabuto, who warns Naruto that he would kill him if he does not stop interfering.
