You are Osamu Dazai's younger sister, and as per usual Dazai is in trouble again. He's been captured by Master Chen to have you participate in the Tournament of Elements. Dazai may be in many tough situations, but this time he can't get himself out of it. So you being his caring younger sister that you are participate in the tournament to save him. But you also encounter Ninjago's ninja and Garmadon along the way. Not only that, but you might also catch the eyes of a certain green ninja there too.
