True Face of Sasori
With his puppet destroyed, Sasori reveals himself to Chiyo and Sakura, looking no older than when he left his village twenty years ago. As a further bit of nostalgia, he produces a summoning scroll and calls forth the Third Kazekage, whom Sasori has made into a puppet. Using its weapons, which are even more dangerous than Hiruko's, Sasori is able to catch Sakura in a poison gas cloud. Meanwhile, Kankuro, Temari's team, and Ebizo make their way to the Akatsuki hideout.
