Naruto: Shippūden (2007)

S6E116 Guardian of the Iron Wall

Sasuke's team gains its second member, a woman named Karin. Upon arriving at the Southern Hideout, Sasuke asks her to join them. Although Karin is initially reluctant and has some disagreements with Suigetsu, she ultimately agrees after recalling her first meeting with Sasuke. Sasuke then instructs Suigetsu to free the prisoners, and once that's done, they head out to find the last member of their team, Jugo.
