There is no CS 3 in Naruto. Point.
There is no innovation in this thread that can somehow be done really...
There is no SST in Naruto. Point.
Hmm what about like Lebis said, various stages of CS2?
although it has not been proven in the series, a CS3 could possibly exist. If so, saskue is going to be first to achieve it.
An event like now, only involving more people, each person is a personal stage, the difficulty shouldnt matter for us, its the thought that there IS a greater power that counts
Of couse, most of us realize your time problem, but can't you just put this off after whatever is last?
