A Battle to decide them all

"Now, we will move on to Alix and Sven, duel well."

        Aidan unsummoned the demons and joined Roren behind the bar as I took the floor with Sven. He had his whip in hand and cracked it once for emphasis.

"One, Two, .....THREE!" And we were off. Sven immediately swung the whip at me. I ran at him, too close for his whip to hit me. I immediately disarmed him with a strike to the wrist with the flat of my blade. he dropped it, and grappled with me. He grabbed my wrist and twisted hard. It hurt terribly but I held onto my sword.I head butted Sven and backed up. He tottered for a second and then shook his head to clear it. He reached for his back and pulled a long thin blade. He held it out sideways, defensively, and the air around it began to crackle. Lighting danced off the blade, and he swung it at me, a bolt of lightning shooting out the end.

"SVEN!" Roren shouted over the crackling," This is a test fight, not a death match, concede you lost and let's go!"
"This effing kid needs to pay for his actions! I will defeat him and show that he and that bastard Aquila don't know what they're talking about!"
"Alix, hold on, I'll stop him!"
"There's no need, I can handle this!"
"Then take this advice, copy his technique, for the lightning blade will cut through a regular one."

    I nodded and focused on what he had done. Suddenly, a voice spoke in my head, a deep gravely one: "You're trying lightning? That is a weak element, use your inborn one! Show these people your true power!"The voice faded and a new technique flooded my consciousness. I pushed the power down into my blade, and a black flickering glow surrounded it. Then I noticed Sven was gone. I quickly recalled Roren's sensory technique and applied it, just in time, and I ducked under Sven's blade. I swiped up towards his groin, but he blocked it and came at my head. I caught the blade and pushed it away, and swung at his leg. He jumped over it, and made a direct overhead strike. Instead of blocking, which would have opened me up for a kick and defeat, I stepped in and brought my blade down on his shoulder. I got sprayed with blood as arm and sword hit floor. I deactivated my blade and put it at his throat.
"You've lost, official Sven."
He glared with all the anger in the world and growled, "I submit."
I lowered my blade and made to leave,turning my back on him. I was sent an image of him lunging with his blade at my back by the sesnory.
"ALIX,WATCH OUT!"
But his warning was too slow, I had already turned and I caught Sven's blade. I shoved it away, and it skittered across the floor. But I didn't stop, I immediately stabbed Sven straight through his heart, and he fell to the floor, coughing up blood. And there I left him, bleeding to death on the floor of the training room.
