Naruto's School of Revenge

is episode 181 of the Naruto: Shippūden anime.

Summary
The story begins with Naruto, Sakura Haruno, Inari and Tazuna sitting together and remembering the days of the original Team 7. The team was on a mission of having to return Mr. Ostrich to his habitat. Mr. Ostrich is very fond of pecking Naruto and Sasuke onto their heads. When travelling through what it seems like a small city they encounter a vendetta (the challenger is fighting for the revenge of the deceased family member). The fight participants are Tsukado (challenger) and Kageki. At first look, Tsukado looks like an amateur fighter, always inferior to his opponent. Naruto said that he will teach Tsukado how to gain victory in his fight, but the training was not successful. After Ostrich gone wild, Tsukado revealed his sword skills, explaining that he cannot win because he cannot look straight into Kageki's eyes. Meanwhile Kanabun and his gang organised the fight once more. Tsukado thought he could win by not looking into opponents eyes but he did not succeed. Naruto, seeing something is not right interrupted the fight. Kageki discovered that he is not the man Tsukado's looking for, explaining that he (Katazu) took the role of his brother because he believed that the murder was an accident. Tsukado believed in this story and he cancelled his vendetta. But the gang did not like this ending because they placed bets. So the fight began. Joint forces of team 7, Tsukado, Katazu and Mr. Ostrich managed to gain victory.
