I challenge you(or do I?)seriously, あなた may enjoy this very much.

k, so what I challenge あなた to do is come up with an idea for a play/movie (I know this will be easy fo some of あなた because あなた guys ar all very creative)
What does this have to do with ヘタリア あなた ask?well, I want あなた to cast the ヘタリア characters as those of the ones of your play/movie idea based on their personalities.

Have Fun!!
