The reason behind the mess

My throat was burning. It was just a side-effect of my flames consuming most of the air around, the flames that quickly found their way into my throat with every desperate breath that I made. 

Still, the pained throat was the least of my troubles. Because after turning the two men that attempted to kill me into a crispy steak of blackened human shape, a new, weird feeling spread out through my body. 

I was lacking oxygen. My raging emotions only exacerbated the problem. And then this weird feeling, as if yet another force was trying to guide my body against my will. 

There was no intent behind this last feeling. It felt as if my body suddenly woke up from ages-worth of training, instantly feeding all the muscle memory into my flesh itself. 

My movements became swifter, more fluid, even though all I did was slowly walk forward.
