Synopsis
Freed, Choji volunteers to stay behind and deal with Jirobo to give the rest of the team a chance to catch up to the other Sound Four members. As the team goes on, Choji eats the first of the Akimichi's Three Colored Pills, increasing his strength. Doing so proves enough to overpower Jirobo, forcing him to advance his cursed seal to its first level. With Jirobo now having the upperhand, Choji takes the second Akimichi pill.
