In Japan's Warring States period, Lord Daigo Kagemitsu makes a pact with 12 demons, offering them his unborn son in exchange for the prosperity of his lands. Years later, young thief Dororo is attacked by a ghoul but rescued by a mysterious boy, whose body parts turn out to be almost entirely prosthetic.

Dororo and Hyakkimaru happen upon a village and are brought before its chief, Lady Bandai. However, Hyakkimaru inexplicably draws his sword in her presence, resulting in both him and Dororo being locked in a storehouse by the villagers. It turns out they are not the only ones confined there...

Jukai is a doctor who travels the land fitting prosthetic arms and legs to those who have lost their limbs in war. One day, on the riverbank he finds a baby missing most of its body parts. He decides to raise the child, who he names “Hyakkimaru”. Jukai provides the child with prostheses, but the time comes when Hyakkimaru sets out on a journey to recover his own body parts.

Dororo and Hyakkimaru come face to face with Tanosuke the Slaughterer, who wields a cursed sword in which a demon dwells. Hyakkimaru narrowly manages to repel Tanosuke, but the demon blade falls into Dororo’s hands and begins to take control of him.

Hyakkimaru discovers too late that sound is deafening.

Hyakkimaru regained his voice in a fight with a demon, but lost his leg in the process. After returning to the run-down temple to allow his wounds to heal, he once again sets out to confront the demon. Meanwhile, Mio and the children wait at the temple but...

The spider-like ghoul Jorogumo is wounded by Hyakkimaru. To heal itself, it transforms into a woman and takes advantage of the hospitality of a young man named Yajiro. Having let Jorogumo slip through their fingers, Dororo and Hyakkimaru stop at a village where they hear rumors of a kidnapper at large.

At a certain village, young girls are offered up as ritual sacrifices to appease a giant centipede demon that appears shrouded in black clouds. Hyakkimaru and Dororo team up with Saru, a boy whose older sister has been offered as a sacrifice, and together they confront the demon.

Dororo remembers the past while stricken with fever.

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.

After entering Lord Daigo’s domain, Dororo and Hyakkimaru hear tales of Banmon, the huge wall that is the last remnant of a fort that once stood on the border. Hyakkimaru squares off against the fox demon that haunts the wall.

A father once sacrificed his son for power. Now, he must face a reckoning when his son returns.

Having left Daigo's domain, Dororo finds a statue of Fudo, one of the wisdom gods. But the statue is actually a demon that is harvesting humans' faces in an attempt to find one for itself.

Dororo and Hyakkimaru come across an abandoned, burnt-out temple, where they meet a man named Sabame who rules the surrounding area. Sabame invites the two of them to his residence and tells them the story behind the burnt-out temple and the ghoul that haunts it. However, Dororo and Hyakkimaru suspect that he might not be telling the truth.

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.

Dororo has been captured by Itachi and is being taken to the cape where Hibukuro supposedly hid the money. As Itachi and his men look for boats to get across to the cape, they are approached by a one-armed boy named Shiranui.

Jukai is reunited with a bloodied Hyakkimaru at the site of a recent battle, and finds out the truth of how Hyakkimaru and the demons are connected. Hyakkimaru asks Jukai for a new prosthetic leg, but...

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.

While traveling along a mountain path in search of a demon, Dororo and Hyakkimaru encounter a young man named Dice-spot Saburota. The man says that he too is hunting the demon, and they set off to exterminate it together.

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.

Inside Daigo's castle, Lady Nui appears before the cell in which Dororo has been imprisoned. Meanwhile, Hyakkimaru is also approaching the castle as he tries to take back both his body and Dororo. Behind Hyakkimaru stands Midoro, who has transformed into a ghoul.

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.

Daigo's castle is engulfed in flames. Within, two brothers by blood are at the mercy of fate. Dororo, Jukai and Lady Nui also head for the castle, each with their own thoughts weighing down upon their hearts. For a life that began with a silenced cry, where will the path of destiny lead?
