For the Sake of Those Precious (大切な者の為に, Taisetsuna Mono no Tame ni) is chapter 217 of the original Naruto manga.
Gaara's defence proves stronger than Kimimaro's attack. Defeated, Kimimaro finds solace in that, when he dies, he will continue to live on in Orochimaru's heart. Gaara tells him he has been brainwashed and buries him underground. Kimimaro attacks again as he sinks, sprouting a field of bones from the ground, but Gaara protects himself and Lee from damage. Kimimaro emerges from one of the bones, telling them he was not brainwashed and preparing another attack. He succumbs to his illness before he can follow through. Lee and Gaara discuss Kimimaro and how strong he was, which Gaara observes to have been because he fought for Orochimaru. Even if someone is evil, people who consider them precious will always fight for them. At the Valley of the End, Naruto finally tracks Sasuke down.
