Moyako Somaki is a supporting character in the anime Kamisama Dolls. She lives in Karakami village and works as a kakashi repair and maintenance specialist, assisting her grandfather in the craft of maintaining the wooden god dolls that are central to the story. She is an engineer by trade, knowledgeable about the construction and inner workings of these dolls, and she shares some of those secrets with Hibino Shiba when the group visits the village.

Her background ties her closely to the main conflict. She has been childhood friends with both Kyohei Kuga and Aki Kuga, and she is the older sister of Yurako Somaki and the daughter of Leiter, a powerful figure in Utsuwa City. Her motivation stems from her duty to preserve the kakashi and the traditions of the village, which she approaches with quiet competence and a practical mindset.

In the story, her primary role is to provide essential technical support. After Kukuri, Utao's kakashi, is severely damaged in battle, Moyako repairs it, allowing Utao to continue using it. She also trains Utao in handling the doll after the repair, demonstrating her skill and patience. Her interactions with other characters are largely professional and helpful, though her familiarity with Kyohei and Aki hints at shared history.

Moyako does not undergo major personal growth over the course of the series; she remains a steady, knowledgeable presence who ensures that the kakashi function properly. Her notable abilities lie in her expertise with the dolls: she can repair even severe damage, understand their complex construction, and guide others in their use. Her calm, capable demeanor makes her an indispensable part of the village's infrastructure.
