Dororo to Hyakkimaru - episode 24 - 13 Sep, 1969

Dororo's arm becomes caught in a fish-trap, and Hyakkimaru goes looking for help. He finds a nearby temple and meets the monk Nyudo Shiki who willingly lends him a tool. However, when he returns to the river, Hyakkimaru finds Dororo gone and he challenges the suspicious monk who changes into a demon and escapes. Hyakkimaru then encounters a woodcutter who tells him that years ago, the monk refused to surrender the temple to a warrior general and was buried alive, but then mice, frogs, otters and weasels then attacked the general and saved the nearby villages. With the help of the woodcutter, Hyakkimaru rescues Dororo and kills the demon which bestows on Hyakkimaru the ability to feel heat, cold and pain within his body. (Source: Wikipedia)
