Well, Team 7, Naruto, Sai, Sakura, And Yamato Came To Help Fight Kakuzu And Hidan. Kakuzu, However Did Not See Naruto As A Threat, This Changed When Naruto Unveiled His Newly Developed Technique, Wind Release: Rasenshuriken. Then Kakuzu Knew That It Would Be Dangerous If It Had Hit Him. Kakuzu Had Attempted To Crush Naruto, And Did, But It Was A Shadow Clone. Kakuzu Then Was Defeated By What He Called "Kids".
