I need help with a cosplay. For Otakon this year I have bought/made a ninja outfit from the anime Naruto. I have a leaf village headband, gloves, vest, and the clothes and all but I need a back story for th cosplay. I know hand signs and all but I am not cosplaying a certain character just a random ninja from a certain village. Could anybody give me a back story to use for this random ninja cosplay?
