Yeah, A Rank......
Chelsea was happy nonetheless, but knew that higher rank means more complications and more efforts, but she was ready to put everything in it, nonetheless.
Rank: A
Type: Attack
Range: Short
Chakra Cost: 30

Description: Rasengan was a Ninjutsu technique developed over the span of three years by the Fourth Hokage, Namikaze Minato. The technique was taught to his sensei, Jiraiya, who then passed it on to Minato's young son, Naruto, years later. The technique is unlike many other jutsu in that it does not require any hand seals. It just relied on the ninja's ability to mold chakra. The ninja concentrates a contained, fast, rotating sphere of chakra in the palm of their hand, which can create a destructive impact.
Advantages:
-Doesn't require any handseals and hence technique is almost instantaneous making it way a lot of useful, based upon user's creativity.
-It just requires molding of chakra, no need of scrolls or weapons. I can add elements into it to make it elemental rasengan.
Disadvantages:
-Can be used only at short range and hence needs you to reach at cnc range from your opponent, which is tricky part of the technique.
-It is very specific when it comes to application and attacks as melee attack only, making it completely useless as a projectile or any other type of continuous attack.
Combinations and Strategies:
-Can be used alongside suitable elements to overwhelm my opponent's defensive jutsus. Such as, I can use lightning rasengan, to overcome doton defenses at short notice etc.
-Sometimes getting at closed range from my opponent is really tough and hence one needs to use it alongside diversion tactics, like Naruto uses shadow clones as a diversion to get near his opponent.
Counters:
-It can be countered by getting out of the range of the technique. One can use simple techniques on ground for that purpose.
-I can also use powerful long range attacks which cover large amount of ground to take down diversions as well. Though it is chakra consuming and using simple defenses is always a solution.
Demonstration:
Chelsea first gathers all her chakra and then focuses required amount of chakra in her right hand. She then molds the chakra at the palm of her hand and shape manipulates it in the form of concentrated orb of chakra then molds the chakra in sufficient amount to give it rotation ability and then maintains it.
Then she runs towards her opponent and after reaching at short range from her opponent she then hurls that rotating sphere of chakra in your clone's stomach. The rotating sphere of chakra has enough amount of strength and rotating speed to completely destroy the inside muscles and organs of stomach on your clone and is destructive enough to make him disappear due to the hurling pain.
One down, one more to go.
Rank: A
Type: Attack/Defence
Range: Short
Chakra Cost: 30
Damage Points: 60
Description: By combining the original Rasengan with an elemental affinity, a new Rasengan can be created that may produce a variety of effects. Only the basic 5 elements can be used in this technique.
Advantages:
-Can be used to provide different effects to the rasengan. For example, Doton Rasengan to make it heavy, Raiton rasengan to increase it's penetration, fuuton rasengan to increase it's cutting ability etc.
-It can be used to break down enemy's defenses, after hurling him using an element which is strong against the defensive technique element he used.
Disadvantages:
-Again Rasengan's problem of range isn't solved here.
-Also it is really difficult to change from one element to other when you are at sufficient range and is almost attacking the opponent, making it really difficult to overcome high ranked defenses.
Combinations and Strategies:
-Can be used alongside diversion, but this time alongside clones, which themselves can use few ninjutsus to attack opponent from all possible directions.
-Can also be used alongside chidori or other ninjutsus to attack opponent via ground, when I attack via air or attack from front side.
Counters:
-Can be countered by using defensive techs or getting out of range of the technique.
-I can use something like transformation jutsu to sneak behind my opponent and catch him offguard as rasengan completely leaves back of opponent vulnerable.
Demonstration:
Just like previous jtusu, Chelsea again gathers her chakra and then focuses the required amount of chakra in her right hand. Now, she shape manipulates it in the form of sphere and then molds it in the form of compressed sphere of chakra with rotation provided to it. She then kneads her chakra and then element manipulates it in the form of Katon which she then adds into the already formed Rasengan.
She then runs towards her opponent and after reaching at short range, she again hurls the rasengan, this time near the chest part of your clone to deliver sever burns due to the fire element.
After doing so, she then forms the rasengan again, but this time element manipulates her chakra in the form of Raiton element, which she then adds to the rasengan.
She again hurls the rasengan at your clone, which now produces electric shock like effect and hence few sever cuts and burns are inflicted at the stomach part, where she hurls her elemental rasengan.
After that she again gains her chakra and then shape manipulates it in the form of rotating sphere of chakra, maintain it in her hands and then element manipulates her remaining chakra in the form of fuuton and this time hurls at the chest part of your opponent.
Fuuton chakra has better cutting abilities and hence produces some sharp cuts which leads to bruises.
Then while your clone is at trouble she forms Rasengan and adds suiton chakra to it, to give it fluid like properties, which she hurls at the backside your clone, due to which your clone is sent flying.
One last time...
Now she gathers her chakra and then focuses it in her left hand and the molds it to form the Rasengan sphere with rotation. She then adds Doton chakra into it, giving it mass and weight, making it heavy. She then hurls the Rasengan at the stomach of your clone. This rasengan is as heavy as stone and hence upon impact is powerful enough to send the opponent flying.
Finally done, that was tiresome though
She sits under the nearby tree, waiting for you to show her new trick.
