AND THEY STAY THERE ! <| sep |> Well let ' s hope for the best and prepare for the worst . Thank you for the info ! <| sep |> To the point the difference between chidori and raikiri , is that whereas chidori is a pure nature transformation , Kakashi took it one step further and applied shape transformation by shaping the chidori into a blade which increased the jutsu ' s lethality immensel , and also made the jutsu much harder to learn and perform . This , is what the raikiri is . It is the combination of the lightning nature with the shape of a lightning . Kakashi disagreesAlso , if chidori is just raikiri without shape transformation , then explain how can Sasuke use chidori in various kinds of form basic chidori stab , the famous chidori sword , a chidori sword with impaling tip , chidori needles , chidori current ? I would even say Sasuke ' s chidori has more diversity in shape than Kakashi ' s raikiri .
