A village within Daigo's domain is being terrorized by a ghoul that dwells in a nearby lake. Tahomaru, accompanied by his aides Hyogo and Mutsu, volunteers to exterminate the ghoul.

Sabame has been feeding people to the demons to protect the village over which he rules. As Hyakkimaru once again confronts the demon moths, Dororo gets trapped in a storehouse.

The shark demon lets out a roar and attacks Dororo, who is tied up and unable to move. Meanwhile, a troop of soldiers commanded by Tahomaru is also approaching the cape.

To fix Hyakkimaru's broken sword, he and Dororo travel to a village where a master swordmaker named Munetsuna lives. Upon arriving at Munetsuna's house, they are met by his daughter Okowa.

Daigo Kagemitsu continues to prepare for war with the neighboring land of Asakura. Upon receiving word that Hyakkimaru is approaching his domain, Kagemitsu sends Tahomaru to dispose of him.

Hyakkimaru comes face to face with Tahomaru, Mutsu and Hyogo, who have been possessed by the power of demons. Dororo, Lady Nui and Biwamaru hurry to the scene, where they witness a ferocious battle that will determine the future of the land of Daigo.
