Well, first you find a sensei to teach you jutsu, once you learn jutsu you can engage in battles with other members using the jutsu you learn. You battle by posting your move containing your jutsu and what you do with them, then the opponent posts thier counter and so on and so forth.
your strength is determined by the amount of posts you have but try not to spam in an attempt to raise you post count.
