Im unsure whether this version of the water technique is a continuous release or a simple "expulsion" of water. Its been displayed in the anime but I haven't had time to watch it yet.To begin i focus my raiton chakra and I then channel it into my right hand. There I begin to amass my chakra, quickly building up my chakra until i have a sufficient amount. I then focus my chakra around my hand while simultaneously using both nature and shape manipulation to transform my chakra into lightning and then form it around my hand. I then jump into the air and condense the lightning before launching a bolt of lightning at your clone. It races towards him and strikes through him, causing him to disperse.
Adv-No hand seals
The lightning bolt is large and fast, making it difficult to directly dodge
Disadv-You have to jump into the air to use this technique
I rate your counter as bad. The lightning once coming into contact with the defensive wall of water will conduct up through the water and to you, shocking you. So this doesn't really defend you at all.
I rate this techniques speed of use as medium. It requires no hand seals and lightning is naturally fast but it still takes time to travel plus having to jump into the air before you use it slows this technique down.

(Raiton: Raikiri) - Lightning Release: Lightning Blade
Rank: S
Type: Offense
Range: Short
Chakra Cost: 40
Damage Points: 80
Description: This jutsu is an advanced form of Chidori.
First, perform the basic Chidori. After performing it, increase the chakra supply to the Chidori greatly, as well as condensing the chakra down even further to make the Raikiri more stable and deadlier. It should end up as a mass of concentrated blue chakra in your palm.
