Yokai Kozo (妖怪小僧, Yōkai Kozō) is the benevolent spirit vessel that houses the deceased children who once lived in an orphanage in the mountains. Some time ago, they, along with the nun, and the orphanage itself, burned down in a fire by Sabame after they discovered the landlord made a pact with Maimai-onba to keep the land prosperous by sacrificing people to feed the demoness and her offspring. Since then, the orphans who were sacrificed came together and created this spiritual form.
Yōkai Kozō takes the form of the giant fetus-like monster gathered by the many deceased children spirits. It has an overly-large, bulbous head, with a protruding lump on its forehead. It has big eyes with droopy eyelids and appears to have exotropic strabismus, and has no eyebrows. It has saggy and puffy cheeks, an absent nose, and an odd-shaped mouth resembling puckered lips.
As seen from Episode 14, he is rather playful, especially around Dororo, as he often harmlessly tackles him to the ground and snuggling him. Before doing so, he stretches his hands out towards Dororo and moves towards him while exclaiming "num-num!". When travelling with Hyakkimaru for a short period of time, he also likes to carry Dororo in his arms. However, Dororo does not like it, as he often screams and struggles in vain.
As much as it is playful, the Yōkai Kozō is also kind and cares for the well-being of others who have given it attention as well as shown it kindness. When Dororo was cornered by Maimai-onba's children in larvae form, it intervened in the nick of time and saved his life. When Dororo asks why, it replied with "Dororo is kind. So I save Dororo."
