Since leaving Daigo’s lands Hyakkimaru has barely slept, as he seeks out any and all demons to kill until all of his parts have been returned, and Dororo is worried about him. He suggests they head to a hot spring for some rest and recovery, but has to lie about there being a monster there to get Hyakkimaru to go along.
Turns out Dororo’s only half-wrong: there is a monster in these parts, but it can be found under a waterfall. A great stone statue possessed by a demon cleanly cleaves the faces off victims. A woman with long black hair is delivering these fools to be de-faced, and she in turn can look and sound like anyone.
When Dororo encounters the statue while collecting firewood, the woman appears as his mama, and the resemblance and sound of her voice are so familiar he can’t help but want to call her Mama, which she allows (her real name is Okaka).
As Hyakkimaru dozes, Okaka tells Dororo the story of the statue, a giant Fudo that was to be a scorned carver’s masterpiece and thumb in the eye of his detractors. But he never completed the face, working himself to death but never satisfied with the results.
As Dororo starts to nod off, Okaka reveals that she drugged the both of them, and that she is in fact the carver, revived by a demon to complete the Fudo’s face. And Okaka thinks she’s finally found the perfect face in Hyakkimaru’s.
When Dororo comes to, he’s just in time to slow Okaka down before she can place Hyakkimaru in the path of the Fudo’s giant sword; that buys enough time for Hyakkimaru to wake up, cut himself free, and start hacking at the Fudo, much to Okaka’s chagrin.
Dororo, whose guileless kindness has clearly had an effect on Okaka to this point, manages to convince the carver of the madness she has wrought. Okaka doesn’t know how her obsession with artistic perfection has turned him into a murderer.
The demon within the Fudo isn’t so contrite, however, and it slashes Okaka nearly in half with its sword. Hyakkimaru finishes it off, and the demon disperses, but before Okaka dies and turns to ash, she asks if she can feel Dororo’s smiling face—like the kind face of the Buddha statues she once carved.
Dororo apologizes to Hyakkimaru for getting tricked by his mama’s face, but Hyakkimaru tells him out loud that he’s fine, and that they should proceed to the hot spring to rest. Once they get there, they find Biwamaru is already there (and he believes they were fated to keep meeting like this).
They also encounter a father and two rugrats who jump into the spring and splash about, disturbing the tranquility. But they also notice something on the annoyed Dororo’s back: an elaborate red tattoo that looks like some kind of map. That just may indicate where they should head next, as they’re currently lacking a set destination.
Dororo returns with a new OP (not as good as the first but still nice), ED (wonderful vocals with somewhat muddled visuals, though that’s probably the point), and demon-of-the-week. We also learn Hyakkimaru’s mom is still alive (though not in good shape) and that Daigo believes his deal with the demons is still in effect, but who knows for how long.
