-Kankuro walks over a large sand dune and waves at his brother-
So brother it looks like you want to learn my hidden sand jutsu eh ?
But first things first. Before you learn these Jutsu's of mine I need you to know that you can never use these jutsu's against me in battle, so please sign this scroll of mine. If you disagree we can both head on home.
-Kankuro pulls out a scroll and shows where to sign-
