Sparrow and Robin are traveling merchants
Sparrow is the sneaky type, shes smooth with her words, i usually draw her a bit thinner than depicted here but i couldnt get it to look right for some reason
Robin is her brother, he's the more dependable type, but he prefer to sit and write while Sparrow sells their wares. He was also born blind.
Their leaves help them transform, they are shape-shifting foxes after all. They claim foxes are better at transforming than tanukis, but tanukis claim otherwise.
