Episode 72

Tōtōsai's Rigid Training is the 72nd episode of the InuYasha anime.

Plot
Inuyasha goes to Tōtōsai to learn how to break Naraku's barrier. He finds there that a young demon of the lynx tribe named Bunza is trying to become an apprentice for the very same reason: to break a barrier that the enemy of his tribe has built around them, trapping them away from their hunting grounds. Inuyasha and Bunza think that the tasks that they have been assigned are training, but in fact Tōtōsai simply wants them to prepare a bath for him. As a lynx messenger comes and tells Bunza that his father tried to attack their enemy, Nanafushi, Bunza rushes off to his father's aid. Inuyasha then accompanies Bunza to try and help the lynx tribe to get rid of Nanafushi, the giant mantis. He breaks the barrier with his wind scar and kills the demon. Finally he leaves Tōtōsai before he learns anything new, but Tōtōsai tells Myōga to pass on the method for breaking barriers to Inuyasha.
