"Jinchūriki…!!" (人柱力…!!) is chapter 261 of the original Naruto manga.
Out of curiosity Sakura questions Chiyo about jinchūriki, individuals that have had a tailed beast sealed within them. Experiments intended to help in controlling the power of their tailed beast, jinchūriki have access to great power, power that interests Akatsuki. Sakura asks what will happen to Gaara or any other jinchūriki that has had its tailed beast removed. Chiyo says they will die. Sakura worries about Naruto, but he says there is no need. They continue towards Akatsuki's base. Akatsuki, meanwhile, finishes extracting Shukaku from Gaara's body. At that same moment Team Guy arrives outside.
