Synopsis
Sasuke decides to go to Orochimaru in order to get stronger, and accompanies the Sound Four back to his lair. Upon learning of Sasuke's defection, Naruto accompanies Shikamaru Nara in assembling a team to retrieve him, and the two gather Neji Hyūga, Kiba Inuzuka, and Chōji Akimichi to their cause. The team pursues the Sound Four until they are trapped by Sound Four member Jirōbō, who distracts them while the rest of the Sound Four goes on ahead. Chōji is able to free the team from Jirōbō, and begins to do battle with him while the others continue their pursuit. Chōji and Jirōbō have a battle of strengths, with Chōji eventually claiming victory.
