You are the killer?

Two figures stood there on the rooftop with a few meters between them. One of them was holding a slightly curved sword that was spewing red fumes, while the other was barehanded with a dagger lodged into his shoulder. 

Crey slowly breathed, then grabbed the dagger on his shoulder and pulled it out. A slight gasp escaped his mouth, as the dagger fell down with a clatter. Knowing it's now a life-or-death fight, he realized he has to give it his all this fight.

"Tch! No weapon. Are you….."

The mysterious man ridiculed Crey after seeing him still standing without any weapons in his hand. But his comment died in the middle as Crey uncovered his arms from his cloak, which was hiding his figure. He quickly shed it to reveal a slightly battered, yet mostly fine Kevlar Combat Suit underneath, which made the man a little surprised.
