*First jutsu*
When I recieved the lighter from my sensei,I threw it in front of me. While it was fliping in the air with,I used my Katon chakra to turn the small open fire of the lighter in the massive fire wall. This massive fire wall repeled the sensei's clone which was rushing towards to inflict me some taijutsu damage.
This jutsu can be used to repel some basic attacks like small projectiles or some taijutsu attacks,but it can't be used as a defence against some advanced and more dangerous jutsus,because they can just go through the flame and inflict some damage on the user.
Also it can't be used at all times,because user needs some external fire source for this jutsu. Also the good side of this jutsu is that it doesn't require andy handseals so it can be performed pretty fast.
*Second jutsu*
First I start by performing a single tiger seal,and then I mold some katon chakra into my lungs. When I gathered the right amount of chakra for this jutsu,I released it from my mouth in a form of a stream. While it was passing through my mouth I used shape manipulation,to change the stream into a circle. When it was launched,the circle went flying through the air towards the clone. On impatc,the circle completely enveloped the opponent and deal his some serious burns.
This jutsu requires only one handseal so it can be performed quickly. It has two forms so the user can't be always sure against what he is dealing with. It can also be used with some fuuton jutsus to increase it's damage,which is a big plus.
