Re: katon with Akihiko sensei
Hm...interesting observation of jumping into the air. It does give a wider field of vision of the battlefield, that's for sure.
Furthermore, this allows for direct impact from the sky (also, remember the law of gravity, objects falling down often have greater impacts) and it also allows you to avoid earth jutsus at the same time. (Two-in-one actually). Lastly, it gives you a better field of vision on the battlefield.
For this next one, please proceed to spit out Fire Chakra once again in the form of gas (free-flowing molecules). Then, guide this ash towards my clone, causing it to surround him.
When it does so, give you and I time to run away...then click your teeth and cause the ash to explode!
