Mugen no Juunin: Immortal

Synopsis

Meguro, Tanpopo and Magatsu shelter from the snow in a hut while Rin and Manji recover from their ordeals. However Renzo still seeks revenge against Manji and proposes to sever both of his arms. Both Rin and Magatsu stop him, and Magatsu suggests that Renzo find out more about his father before blindly seeking revenge for his death. Meanwhile, Ryo volunteers to accompany Lord Habaki's man Ban in a dangerous pursuit of a small band of Ittou-ryuu led by Koji. Ryo realizes that Ban is preparing to desert, but they are attacked by the Ittou-ryuu who have laid a series of booby traps. Fighting together, they survive the attack but Ban is overcome by carbon dioxide fumes in the thin mountain air which is emanating from multiple jars of carbonic acid that Koji had placed in the woods. Koji kills the hallucinating Ban, and pursues Ryo who is also succumbing to the fumes. He finds her semi-conscious, but as he is about to kill her, she springs a trap of her own and kills him. Later, she is found by Lord Mitake and taken to Giichi for protection as she is the last person carrying Kagimura's blood. Meanwhile, Kagimura plans to eliminate the remaining Ittou-ryuu before they reunite.
