Inhabitants of Munia are able to feel people’s “percentage of goodness”. Niki Batsprite is a half good and half bad creature, and he’s the champion of acrobatic flight races. He’s forced to care of Moari, a sweet and lively rabbit from whom the balance of Munia depends on. Pity that Niki is much more interested in his career as an athlete! Will they get along and succeed in keeping their world safe?
