Tournament

Y/N POV

Darius was up first and well after he saw Akeno for some reason he seemed really angry and when both of them got into the Arena for round two Tsubaki seemed worried at Darius' angry expression.

Darius: Sorry about this Tsubaki but I need to win this and face her no hard feelings.

He slowly approaches Tsubaki as magic attacks were sent flying at him fading about five feet away from him. He reached her delivering a powerful blow to her gut and sending her flying into the wall.

Darius: Surrender now Tsubaki before I hurt you more, as your friend please yield.

Tsubaki: Fine I give up you win Darius

He walked towards her offering a hand both helping her back to the stands while and Issei got ready for our match. Going into the fight I was completely calm as I summoned my sacred heart at the sight of Issei's gauntlet. Rias tried to get me eliminated because I was using a sword but Zayne quickly stepped in.

Zayne: Actually Rias, we didn't ban weapons and that is his sacred gear so if Issei is allowed to use his then so is Y/N.

Sona: He is right Rias we didn't ban anything really except we do have a no killing rule.

Then Rias sat back down pouting. Me and Issei  stared each other down for a moment before he rushed towards me as I used my left arm to block it before bringing Nightfall down on him as it sent him flying back.

Issei: What the hell do you ever sharpen your blade, it feels blunt.

Y/N: Nightfall is never blunt I would look closer.

Across his chest was a large gash as blood seeped from it as he fell to his knees before passing out.

Y/N: Your lucky I held back or that could have been fatal.

Then Zayne brought out a wheel with the three remaining names on it giving it a spin as it landed on Akeno first, then he gave it another hard tug as it spunas it slowed about to land on Darius before it stopped on me. Akeno landed across from me as I felt extreme angry and the heat radiate from the blade, as I charged towards her, bringing the sword down on her as flames arched from the blade before I could continue the attack I felt a shock near my heart as I flew backwards hitting the wall as I felt three more quick shocks, before they just stopped my vision starting to fade before it all went black.

Darius POV

I stood between Akeno and Y/N before she could continue her attacks.

Darius: He has already lost Akeno stop or else.

My eyes narrow at her as the others help Y/N out of the arena to get medical attention in case of any damage, while she was being healed by the blonde girl with twilight healing, while I just prepare for this fight by pulling off my coat and shirt revealing burns from lightning.

Darius: I am going to enjoy this a lot Akeno

After she was done being healed and it was just us in the arena I went straight on the offensive  as she tried her magic only for it to fade out of existence before it could touch me. I kicked her legs out from under her before following with a heel into her gut cracking the ground below her. That is when the fight was called so I picked her up by the throat before throwing her to Rias.

Darius: That was for Y/N L, I'll get my payback later.

I grabbed my coat off the ground as I placed my shirt on and left the Arena to check on Y/N's condition. When I made it to the rest I learned he was stable thanks to Sarah's healing but not conscious.
