Welcome to Gaia! ::

OK. I charge my chakra into the water balloon until my chakra makes it explode.

I looked at him and said, Ok, I think that will be fun.

I see I'm gonna have to use a little more power. I breathe slowly and my eyes get serious. I start to move one of my hands right above the ball as if I was scratching it. I began to move my hands faster while charging my chakra into the ball. I began to move so fast that my hand became a blur. I then made my hand go in one final motion as if I was slashing it with my nails. The ball exploded sending me flying back into a nearby tree.

"Pretty good...now the last step is to gather up chakra and spin it in your hand like in the first step...then make the chakra faster and in different directions like in the second step...and last is to form it into a compact sphere in your palm and keep it that way all the way through your target" Rato walks to a tree "watch...this is how" Rato easily gathers chakra into a ball in his palm and spins it into a Rasengan and presses it into the tree "Rasengan" Rato blows a hole straight through the tree "if you don't keep it in a sphere all the way through the attack this is what happens" Rato spins the chakra into a rasengan again and preeses it against another tree "Rasengan!" The chakra hits but Rato lets go of the control and the rasengan creates a swirl mark on the tree and disappears "now get to it"

Kai did exactly what he said. He did all the steps from his previous training except charged his chakra with one hand, and he made the chakra into a ball but the chakra was strange. It was turning dark red. He then aimed it at a tree and yelled Rasengan! He rode on an airwave straight at the tree to give him extra speed and he hit it, completely destroying the tree. Once it hit the tree an overwhelming force shot Kai back at such a high speed that it send him flying through a tree. He was weak from the amount of chakra used and from the tree injury sustained so he past out there.

He laid there unconscious.

O walked back over to the trees and I began to train. When I completed the rasengan, my chakra had returned to normal. The first time I completed Rasengan, my chakra was dark red and It was so overwhelming tat it completely eradicated the tree. I continued to train until I mastered the Jutsu.
