Charge Tactic! Button Hook Entry (突入!ボタンフックエントリー, Totsunyū! Botan Fukku Entorī) is episode 18 of the Naruto: Shippūden anime.
Kakashi and Guy's teams find out that there is a barrier protecting the Akatsuki hideout, being generated by five forbidden tags in the nearby area. Neji pinpoints the tags' locations with his Byakugan, and Team Guy dispatches to remove the tags and disables the barrier, allowing Team Kakashi to enter the hideout. Meanwhile, the Akatsuki members end their astral projection technique and leave the hideout, except for Deidara and Sasori, who are ordered by the Akatsuki leader to dispose of the intruders.
