hostuma,youre completely ignoring the underlying storyline of emotion,friendship and revenge that is driving each of the characters to reach their limits so they can accomplish their goals. Its like saying a marathon runner gets passed in the last 100 meters on the race and digs deep for extra energy to retake the lead and win the race. Its called perservarance and motivation. Its not like DBZ where they go in a room to purposely reach another level. Levels were never mentioned in naruto besides ninja rank and that means nothing. levels were in dbz from the start they had powerlevel readers for godsake.


And i still think sasuke wont use the curse seal he will realise he own individual potential.
