Mieu is a blue Cheagle. Cheagles are considered holy by the Order of Lorelei due to a pact formed with Yulia, symbolized by the Sorcerer's Ring. The Sorcerer's Ring enables Cheagles to communicate with other creatures and humans, as well as use the power of various Fonons to gain new skills (like flight by flapping their ears). He joins Luke's group when the elder Cheagle bans him for one cycle of the seasons for setting fire to the forest in which the Ligers live, which caused the ligers to hunt the Cheagles for food. Mieu quickly grows fond of Luke, referring to him as "Master," and naively accepting the name, "Thing". Though Luke originally abuses and ridicules Mieu with little provocation, he eventually comes to regret his actions. Mieu, however, thought of Luke's actions as mere play and affection, thanking Luke for his "name". He ends most of his sentences with "desu no".
