Dororo to Hyakkimaru EP22 - The Demon Monmon

Dororo and Hyakkimaru arrive at a deserted village with only one girl inhabitant called Ochii. She tells them that the villagers went to the mountains to look for gold and never returned. Ochii tells them she knows the location of the gold and Dororo eagerly goes with her to see it. Dororo grabs a bag full of gold, while Hyakkimaru who has followed Dororo into the mountains is attacked by the demon Momonga and falls into a river. Ochii is in fact Momon who has lured people into mountains by telling them about the gold, where they are eaten by huge slugs whose slime makes ordinary rocks look like gold. Hyakkimaru kills Ochii and then Dororo creates a fire which incinerates the slugs.
