Oumi is an absolutely rotund red anthropomorphic dragon. He serves as an assistant at a Samurai Training Dojo and generally toward samurais that come and go there. Unlike other Yoriki, he’s tasked with handling much easier things, such as janitorial tasks. While he’s not proud of the way he’s treated by the others, he’s always trying to improve himself—despite his clumsy and gluttonous appetite, which does not make him fit for a true warrior. Oumi carries around a bo-staff for self defense.
