As Alexander waits, he notices a change in shade...all of a sudden his whole area around him turned dark.He looked up and saw a humongous image of an animal which crashes in a safe distance upfront of him, however the shockwave knocks alexander off his feet. Usui's figure emerges from the hand of the great beast, Goruku-king of the chimpanzee's.
" Alrighty than, hope that didn't scare you.What I shall teach you now, is the highest form of ninjutsu, the highest chakra control able to be created- rasengan. Tell me first, what do you think the rasengan consists of, its nature how it works etc"

Good, now take this water balloon and put chakra into it. I want you to burst the balloon using your chakra only.
After grabbing a hold of the water balloon I place it within my right palm and start focusing chakra throughout it. As I keep focusing chakra I manage to see the balloon spinning in a single direction. Knowing this won't be enough to actually pop the balloon I start focusing on rotation my chakra in different directions. Some time later, I manage to see slight dents and spikes coming out of the balloon but still no pop! After careful calculations, I place the balloon on my hand once again and start focusing my chakra inside of it whilst rotating it at even faster speeds as the dents and spikes increase throughout the balloon anddd.....
And...Pop!
"Good work, it took a while but you caught on faster than most! Now..take this rubber ball and trying popping it" *troll face*
A-a-a.... rubber ball? O.O
After being congratulated I grab a hold of the rubber ball and place it on my left hand this time as my right one is rather tired from the continuous chakra manipulation. Following the same principles as before, I start focusing chakra inside of the hard rubber ball whilst rotating it around in several locations. However upon doing so all I notice is the rubber ball barely moving on top of my palm. In frustration and remember one of my compares doing it, I utilize my right hand and start "scratching" the ball around the edges in which I am focusing the chakra. So in unison I am focusing my chakra while manipulating it into a perfect sphere that starts rotating in every single direction, allowing me too.....
Di-di-did... I do it?...:ghehe:
BOOM
"Wow, be careful there. If you put too much power there,you can cause a blast which will certainly not be easy on your palm. Now, I want you to combine all that you learned, and create the same chakra sphere in this balloon. Let me remind you,the goal is opposite of what you have been doing, do not pop it."
-Hands you a bag of balloons-
"Don't expect to get it from the first try"
Following the same steps as before but a bit tweaked, I start focusing chakra inside of the thin and light balloon whilst rotating it around in several locations. However upon doing, I try to imagine a perfect sphere around the edges of the balloon from within, and create a small "coating" to hold my entire rotating chakra in place. All of the sudden, the balloon pops as I lose complete control of the shape manipulation of the sphere.
Nooooo!!
Once I again I repeat the same steps as before, although like with the rubber ball, I utilize my right hand and start "scratching" the balloon around the edges in which I am focusing the chakra. So in unison I am focusing my chakra while manipulating it into a perfect sphere that starts rotating in every single direction, allowing me too create a perfect sphere with devastating power within.
Like this Sensei?
Roger that!"Almost, now you can control it. But we need to put the power to the test, go over to that rock over there.If you can blast a hole into it,than you can consider yourself done with the training."
