The Source?

Holding back the attack I was going to follow up with, I observed the swordswoman who seemed to have noticed that I was planning to finish the battle within the next few moves, and thus wanted to use her strongest attack in response…

'This…'

Not only did I finally understood the reason why the observers had regarded her as a solo fire swordswoman, but I was also given a good jolt of surprise…

'Isn't this 'Raging Fire'...?!'

The 'Elemental Art' that she was currently using was actually quite similar to the one I bought from the system shop, which she was using to completely strengthen her fire attribute using the wind one, thus giving people the impression that she was only using the fire attribute.
