Kiba's Determination!! (キバの決意!!, Kiba no Ketsui!!) is chapter 205 of the Naruto manga.
Ukon is amazed that Kiba would stab himself just to kill him. As Kiba goes for a killing blow, Ukon exits his body to avoid further damage. Kiba takes this time to gather Akamaru and escape. Ukon, exhausted, rejoins with Sakon and demands that, once Sakon has found Kiba and Akamaru, they kill them together. Meanwhile, Kimimaro is able to destroy wave after wave of Naruto's shadow clones, his dancing, acrobatic movements and his ability to use his own bones as weapons being more than a match.
