"The Last Battle!!" (ラストバトル!!, Rasuto Batoru!!) is chapter 273 of the original Naruto manga.
While Chiyo's ten puppets are individually stronger than Sasori's one hundred, they are overpowered in a contest of numbers. Sakura protects Chiyo from any puppets that get too close. Knowing this can't go on forever, Sakura attacks Sasori directly, hitting him with a chakra-suppressing seal. Though the battle seems won, Sasori's body no longer able to move or control puppets, another Sasori appears behind Chiyo. He tries to kill Chiyo but Sakura uses herself as a shield.
