Other World Chimera
Air Bullet

The day after Tomoka's visit, she is seen in her backyard with her father. Today he'll learn how to use air release or at least that's the plan. Tomoka was quite excited. Studying the transformation of the elements both will improve much of his jutsu repertoire. He could even imagine himself opening up some kekkei genkai related to them. Of course the probability of that happening is almost zero. 

“Alright Tomoka, listen carefully. Unlike lightning discharge, the air release is sharper. I spoke to your mother to find a way to better describe it. Simply put, if the Lightning release is a spear, then the air release is a sword.”

With that said Nagi started teaching Tomoka some of the jutsu she knew while guiding her. But before that, he let Tomoka observe his jutsu and how he did things. Tomoka watched without letting even the smallest detail pass. Like before he started using his previous life knowledge to formulate theories. 

'There are several rules that determine the way a fluid moves. For starters, when a fluid is heated, it expands causing its density to drop. For this reason the warm liquid flows upward while the cold one flows downward. 

There is also the fact of pressure difference. Liquids and matter in general will try and flow towards a vacuum to fill it. If I follow this rule, I can create wind by creating a vacuum, putting pressure on air, heating it, or cooling it.

However, I must not forget what happened earlier with my lightning discharge. I doubt the normal air release works as I thought or at least not completely. In fact, some air release jutsu use vacuum cleaners and compressed air. But the way they do it may be different from what I think at a basic level'

While thinking about all this, Tomoka decided to give it a try. He'll try a simple jutsu, Fuuton: an air bullet. Performing a hand gesture, Tomoka followed his father's lead. First he took a deep breath while collecting the chakra in his lungs. He did this while keeping an image of an air bullet in his mind before expelling the air with as much force as he could.   

The end result is satisfactory even though mediocre. From his mouth, a mass of air flew towards the wooden puppet before hitting it. The damage is not good and will hurt if nothing else. However, it's not important. What matters to Tomoka is how his chakra behaves. 

He's correct. Although his chakra compresses the air in a way that feels lacking to him. In the eyes of his mind, he made a visualization of the situation to understand it better. Jutsu felt like blowing air into a balloon before throwing it. 

Following the picture, he began to think. Yes, a regular latex balloon will cause a slight increase in pressure on the air inside. But the increase can be ignored. Chakranya is the balloon. It's his job to keep the air inside. It did its job but the result was still disappointing. 

When he thought about it, he realized his mistake. He had used his chakra after inhaling air. He should have used it before that. By making the container first, he can breathe in more air to fix the previously mentioned problem. 

While Tomoka was daydreaming, Nagi was just observing her. At a time like this he wondered if Tomoka was really still a child. Usually children will become excited after using their first jutsu or become discouraged due to the lack of power of the jutsu. Instead, Tomoka would remain silent. He will be lost in his mind.

Nagi only smiled wryly as she continued to observe Tomoka. As he was about to speak, he saw him doing hand gestures again. That was exactly the same for the air bullet he had just used. Maybe he thought too much about it or he didn't show too much emotion. He thought when he believed that he used the jutsu again out of frustration but ...

"Fuuton: a wind bullet" As he said that, Tomoka took a deep breath. But this time, he pulled out about five times the amount of his small lungs. A moment later a compressed wind bullet flew towards the target puppet. 

*bang* 

With that, the puppet now had a deep hole with broken wood protruding out. A little more and the air bullets will be able to penetrate. With a satisfied smile Tomoka nodded her head, but followed by a loud cough.

[You know at this point I should know better than to tell a stubborn girl like you to be careful but you should take better care of your body. I live here!]    

'Oh shut up, it's just internal bleeding from broken blood vessels in my lungs, nothing serious' Saying that Tomoka swallowed the blood pooling in her mouth. There was no way he would let his father see him. Only God knows what he'll do if he sees it. 

"Tomoka, are you okay?" Of course Nagi became worried. However, she is convinced by her cute daughter that she is fine so she drops it after a while. Like that they continued training for the rest of the day.
