Despair

"What is this?" Evan couldn't believe his eyes. Terrifying energy was emanating from the girl, and a shiver went through his whole body.

"Is it...is it "Gust!?" The dark energy emanating from the girl was actually a definite emotion. The girl stepped into "Gust," and the emotion she was now experiencing became tangible. Evan was surprised at the power of this energy, but what struck him more was that the girl was not a mage.

<She definitely didn't have an ounce of mana in her. How was it possible for her to enter "Gust"? But, it's it, and what's that emotion she's feeling right now?>

A few seconds later, dark energy filled everything around her. It touched Evan, and at that moment, he realized what it was.
