Yagyou-san

Yagyou-san (夜行さん) is a Youkai from the anime and manga series of "GeGeGe no Kitarou". He often rides on Kubinashi-Uma. Throughout the series, his position varies from a higher being similar to a god to an oni of a higher rank although his most well-known career is as an inventor, especially the Youkai Car. In his first appearance in Saishinban GeGeGe no Kitarou, Yagyou-san is described to be closer to a god than Yōkai, and even though he was initially under Nurarihyon's command, he was regarded as higher at rank than Nurarihyon.
