In Naruto world the best jutsu i think its rasengan cuz from rasengan naruto made so powerfull jutsus and in every naruto movies he endes up by killing enemy with rasengan and rusengun effects as a symbol of movie like in 1st movie 7color chakra. 2nd red rasengan on 3rg half odoma half moon. so tell me if i am correct or not tell me ur opinions.
