To Suna…!! (砂へ…!!, Suna e…!!) is chapter 251 of the Naruto manga.
Kankurō has been defeated, his puppets destroyed. He makes one last attempt to strike Sasori; however, having created the puppets years ago, Sasori easily stops Kankurō. Having managed to poison Kankurō during the battle, Sasori leaves with Deidara, knowing Kankurō will die in three days' time. Kankurō loses consciousness and is collected by Sunagakure forces sent to provide backup. Suna's medical-nin can't cure him, but are able to learn that Kankurō's injuries were Sasori's doing. In Konoha, Team 7 prepares to depart. Jiraiya speaks with Naruto before he leaves, reminding him not to use that technique. As they head to Suna they encounter Temari, also on her way back to Suna.
