Plot
InuYasha goes to Totosai to learn how to break Naraku's barrier. He finds there that a young demon of the lynx tribe is trying to get apprenticed for the very same reason : breaking a barrier that enemy of his tribe has built around them, trapping them away from their hunting grounds. As a lynx messenger comes and tell Bunsa, the young demon, that his father tried to attack their enemy, Nanafushi. InuYasha then accompanies Bunso to try and help the lynx tribe to get rid of Nanafushi, the giant manties. He breaks the barrier with his wind scar and kills the demon. Finally he leaves Totosai before he learns anything new, but Totosai tells Myoga to pass on the method for breaking barriers to InuYasha.
