Sarriel's body flickered and she suddenly appeared tens of kilometers from Ryu. Ryu didn't follow up, at least not quickly. He only took a calm step forward, crossing an entire kilometer before taking another step that was just as calm. 

His body was beaten and bruised, his clothing barely covered his lower half, and his blood coated his body. And yet, his aura only seemed to be growing taller and more vibrant. 

Sarriel looked up at the world around her, seemingly analyzing something before looking down at the wound on her arm. There seemed to be a flicker of surprise within as well.

The problem was that it shouldn't be so powerful.
