u guys really underestimated kakashi i mean this is the copyninja kakashi ok first kakashi had no idea he had more then 1 heart which to me is unfair if they faced one on one with 1 heart kakashi would win back to the point kakashi wasnt really tryin his hardest he not once tried to use kumia he was really just running around and only used rakari once and if i recall right it severly injured kakuza and wouldve killed him if wasnt for the multi heart crap kukuza winning against kakashi is like saying pains weaker then kakuza because pain knew kakashi was strong enough to interfere with his plans in the future lastly in the words of minato sensei kakashi would kill kakuza in a flash
