Silent Rewen

The reply shocked X.

What shocked him, even more, was the "aura" around Rewen. The aura wasn't visible but there was a thick sense of danger and creep radiating from him. It was as if he had become another person. 

Rewen's bloodied face showed a dark smile. The "black" in his iris slowly spread into the sclera. Slowly and gradually, his entire eyes became pitch black. His eyes had no reflection. The longer one stares into it, the longer the person gets sucked into the deep abyss.

'I don't know what's going on but I should take a step back…' Being the closest to him, X naturally noticed the changes and immediately decided to step back. 

"Kuhh!"

Just then, he was kicked on his abdomen.

Drawing an arc, he landed on his back.
