*It took a lot of effort for her to not jump out of her skin when she heard the familiar voice of Miya. She had grown so used to relying on her sensory techniques so when someone who could suppress their chakra turned up it was always a shock.* "That's true, to be honest I doubt I'll use fire release much but I want to make sure when I did use it I could rely on it." 

*Quickly she formed a set of hand seals with one hand before a much smaller wave of flame was expelled from her mouth. Another good jutsu but she still didn't feel the same control over as she did with her other elements. Finally she turned to face the chunin.* "Anyway, its good to see you again Miya. I have to ask do you have any advice when it comes to fire release? It's almost completely different to every other nature transformation I've performed."

Miya looked Chinami in the eyes as the genin explained her reasoning for wanting to learn the technique. It was always good to have options in one's arsenal, especially in times of war. Shinobi normally picked up the skillsets they realised they lacked and given that fire was almost exclusively an offensive element, did Chinami think she lacked fire power?

"Why Fire Release?" The stoic Operative inquired before proceeding to answer the genin's question. "Without including Wind Release, it's probably the most offensive basic elemental release that exists. Do you feel that you lack offensive power?"

Miya paused for a second to let her words sink in before she continued. "Unlike water or earth, fire doesn't have mass, making it very difficult to use defensively. When used offensively, it requires very little shape manipulation unlike lightning."

Channelling her chakra and stretching her hand out to the side, Miya performed a quick, one-handed seal sequence before said lightning emerged from her hands. The technique itself didn't look like anything in particular, a single powerful bolt emerging from her palm and moving forward towards a tree.

"Lightning naturally has shape to it, while fire doesn't. If you find yourself using it, you shouldn't try to shape it too much."

"Why fire release? It's nothing really about lacking power although I will admit I'm having issues with that but that's a separate issue. No the reason why I chose fire release is purely because the only choice I had was earth or fire. I thought about it and came to the conclusion a lot of what I could do with earth I can do with Ice. So to give me the most adaptability I chose to learn Fire."

 *Chinami leant back slightly as she listened to Miya's explanation and demonstration of Lighting release. It reminded her that despite being skilled in the nature she did want to learn additional techniques that used it. Of course this was being used to explain fire release to her, perhaps she was restraining herself too much?* "Well I suppose it couldn't hurt to try a little less restraint. I just worry I might end completely loosing control of the jutsu if I do. Oh well I'm going to give it a shot."

*Turning to look back down the range, Chinami formed the seals again. A moment later she exhaled a plume of fire. The flames travelled down the range with a violent ferocity but still it wasn't quite right. They burned bright but almost instantly died down. She knew fire jutsu werent exactly the longest lasting but she doubted anything would be burned with such little exposure.*
