Battlefield

Yusei raced towards the cry, if something had happened to Akeno, then the one responsible was going to pay. He came to a clearing and noticed Akeno was laid out on the floor, her outfit ripped and burnt. Above her was a woman smiling, fire balls in each of her hands. Yusei noticed Akeno turned her head, and smiled gently before she vanished.

"Lady Rias queen retired"

Yusei locked eyes with the bitch who had dared hurt his girl. He noticed the woman was laughing at him.

"Serve the bitch right, she was becoming a real thorn in my side, well little boy, are you prepared to follow her. Allow me to introduce myself I am Yubelluna Lord Riser queen and most value piece, I am also known as the Bomb queen, why you ask, well you're about to find out!" Yubelluna lopped two balls of fire at Yusei, who jumped back as the balls of fire exploded near him.

Yusei retracted his helmet so Yubelluna could see his eyes, they're glowing. "Your little firework display doesn't impress me you old hag! Allow me to show you true power." Yusei replaced his helmet and shot up into the air at blinding speed. He smashed into Yubelluna causing the Bomb queen to cry out. And fly back a few feet. Yusei noticed she smiled.

"Well, it seems Rias does have someone worthy of my time after all. Take this!"

Yubelluna then lopped several more fire balls towards Yusei, who was using his speed to swerve and dodge the incoming explosions. He slammed into Yubelluna once more, and then used his gauntlet hand to smash her in the stomach. Yusei noticed the punch seemed to have winded her. He then focused on his thunder whip and made it materialise. He swung it over his head and then lashed it towards Yubelluna who leg was caught by the whip. Yusei then used his all his strength to swing the whip around his head, with Yubelluna still attached.

Yubelluna couldn't do a thing her world was spinning, as she tried to break the hold this kid had on her. However with the constant spinning her vision became distorted and she had no clue what way was up or down.

Yusei seeing the dazed face, decided to end this little battle. This bitch had hurt his Akeno, and now she was going to pay. Yusei swung the whip over his head, and towards the green mass below their feet. Yubelluna was still attached and she cried out as her whole body was slammed into the leafy undergrowth. Yusei landed a few moments after and retracted the whip, he then stalked towards Yubelluna who was trying to take something in a small glass vial. Yusei knocked the vial out of her hands and then lifted her off the ground to face him. Yusei retracted his mask, so the bitch could see his face.

"You took Akeno away from me, and now I will take you away from Riser!" Yusei then extended his wings and took off towards the sky with Yubelluna gripped in his hands. He looked around and could see explosion in the distance. Yusei headed towards the explosion and was surprised to see Rias, and Riser fighting on top of a roof. Yusei looked at Yubelluna and smiled. He then let go of her. However before she hit the ground Yusei charged his Slifer head gauntlet, before the energy blast was fired he whistled, drawing Riser attention.

"Hey pretty boy, say good bye to your queen. Thunder Force Strike!" The energy blast left his gauntlet and enveloped the falling Yubelluna who screamed as she vanished into light particles. Yusei then circled and landed next to Rias and Asia. He looked down and noticed Issei and Kiba were also on their way towards them. Yusei stood behind Rias and faced down Riser, who was now glowing with a fiery aura, obviously he didn't like his queen being treated like that.

Riser was livid, all his servants had failed him, and now he found himself faced with Rias entire peerage minus two. He thought no one could defeat Yubelluna but that brat who had hit him, had. This just made Riser more angry, and his eyes glowed and suddenly he rose up, fire began to swirl around him, and formed into a giant fire ball with him at the centre.

"This is far from over Rias, you will be my wife, and after this attack nothing will stop that. Now begone!"

Yusei frowned and then quickly jumped in front of the group. He focused on creating a huge shield, which suddenly formed around them. The shield crackled violently as it fought off the intense heat now washing over it. Yusei gritted his teeth he was struggling. Suddenly He heard several boost from Issei.

"Yusei transfer that power to me, I cam amplify it."

Yusei looked towards Issei, and then nodded, he grabbed hold of Issei gauntlet hand and felt his power transferred.

[Transfer!] The shield suddenly increased in size and began to crackle more as it carried on fighting the inferno now trying to engulf them. Eventually the fire died down leaving everyone unharmed.

Riser looked on as the ball of fire engulfed the area that Rias and her peerage had been standing in. Nothing could survive his Phoenix Nova attack, however he was curious, he had expected the voice of Grayfia to announce that house Phenex had won, but he had heard nothing. Just then he noticed something shot from the fire ball, it was a red and black blur that smashed into him. Riser cried out as he felt the very wind punched from him, he then heard

[Absorb]

Riser cried out as the impact had knocked him off the roof towards the floor below. He felt bones crack and could taste his own blood. He struggled to get up and found his vision blocked by Rias peerage who had now transported down to the ground in front of him. Riser slowly got to his feet and spat out blood onto the ground. He was hurting all over, and what was worse he wasn't regenerating. His eyes locked with the red and black armoured foe and noticed the helmet had retracted to show Yusei face grinning.

"You! What the hell have you done to me! Answer me you trash, what have you done to me!"

Yusei just smirked. "Well I even the odds you see it not fair that you can regenerate, so when I punched you off the roof, I absorbed your ability to regenerate, but don't worry it's not permanently gone, you should get it back in a few hours, but by then it will be too late." Yusei looked to Issei "He's all yours." Yusei wanted to find out where Akeno and Koneko was and had decided to leave Rias, Kiba, Asia and Issei, who he was sure could clean up. "Whoever is up there I want out of this game, I've had enough." Yusei looked down at his body and noticed it turned into light particles. Before he vanished he heard.

"One of Lady Rias Pawns, surrendered"

Yusei suddenly appeared in a hospital wing and noticed several people had gathered around him, Yusei pushed them off as they all tried to examine him to see if he seriously injured. However when they noticed he was fine they left him and went back to standby mode for the next casualty. Yusei wondered where he was, the place looked like any normal human hospital, which he found hard to believe when he was still in the underworld. He noticed a man dressed in a white coat holding a clip board. He wanted to find Akeno and Koneko and make sure they were both okay.

"Excuse me, could you tell me where Lady Rias Queen and Rook are resting please." Yusei noticed the doctor looked down on his clipboard.

"There both in room 123, which is down this corridor on the left. Both are in stable condition, now if you excuse me, I have to attend to our other patients." Yusei watched the doctor walk away, he then walked down the corridor and found room 123. He knocked softly on the door and then opened it. He was relieved to see both Koneko and Akeno were sat up in bed, few plasters here and there but nothing too serious.

"Hey you two, how's my two favourite girls." Yusei walked into the room and took a seat between the two beds, he noticed both girls looked anxious and most likely wanted to know the result of the rating game.

"Did we win! Is Rias save?" Yusei looked to Akeno, and noticed the worry on her face. He then sighed.

"Well I left the battlefield, I was worried about you and Koneko, however I made sure I absorbed Riser regeneration ability, so hopefully Rias, Issei, Asia and Kiba can defeat him. To be truthful I could have beaten him there and then, but I know how much Issei cares for Rias, and thought maybe he should be given a chance to prove himself, I just hope I made the right decision."

Back On The Battle Field

All competitors were running on empty, The field around them was a wasteland. After Yusei had left Riser had gained some confidence and was now fighting Rias and her peerage with everything he had. However Riser still had an Ace up his sleeve. He put his hand into his pocket and pulled out a small vial of red liquid.

Rias eyes widened as she spotted the vial. It couldn't be, Phoenix tears, that would heal all his injuries and restore his power levels. This was bad, Rias used all her strength to launch one final attack at Riser who rolled out of the way and laughed as he downed the content of the vial. Rias watched as Riser was surrounded by a red aura, she noticed his cuts began to heal, and he stood and laughed. This was bad, Riser was now at full strength, and she was running on empty.

"You three get behind me, now, Riser just used Phoenix tears, they restore ones strength and power." Rias used all her power to raise a magical shield which was now being impacted by fire ball and other attacks from Riser, who was now laughing manically.

Issei growled, this wasn't fair, they had won, and now this guy had restored his strength and power. They were all sitting ducks, not even his boosted gear could save them, damn Yusei for running out on them, because of his worry for Akeno, he might have doomed Rias. Issei looked to his Sacred Gear,

"Is there anything I can do, that will boost my power enough to beat him, I don't care what it costs, Rias is worth any type of sacrifice. Please Draig you must be able to do something." Issei watched as the Sacred Gear blinked.

[There is one way, I can help, I can allow you to use your scale mail armour ability, it isn't a balance breaker as such, but it will give you the power needed to defeat Riser, but the cost will be a part of your body. That part will belong to me, and it will no longer be human, but dragon. Tell me Issei are you prepared to make such a sacrifice?]

Issei looked up and noticed how Rias was struggling to keep the shield up as Riser bombarded them with attacks, he saw the determination on her face, she wasn't going to let anything happen to them. Issei lowered his head, if Rias was prepared to go this far to protect them, then he was too.

"Draig I offer up my left arm, as a sacrifice to you, now grant me what you promised."

The sacred gear suddenly started to glow and then a loud cry could be heard from it. "Scale Mail armour mode!" Issei was suddenly engulfed by a red light, red armour began to slide into place all over his body, until he was stood dressed from head to toe in shiny red armour, with green orbs spread out across it. Yusei felt a sharp pain in his left arms.

[I accept your arm as payment for this power, but remember, you only have 20 seconds in this armour before it vanishes. One advantage to giving me your arm, it now has no weakness of a devils it is the arm of a dragon.]

Issei let those word sink in, his eyes then remembered something, Devils hated the church, anything to do with it, would cause them pain, his headache when walking Asia that time was prove of that. Issei looked to Asia, he knew she didn't wear the cross but she couldn't resist in carrying it around with her.

"Asia I need that cross you carry around with you. Do you have it?"

Asia was surprised by the request, however she dug into her robe and pulled out the small black box. She then handed to Issei who was now dressed in red armour from head to toe. Issei removed the cross from the box and held in his left hand. He smiled as he felt no pain, Draig had been right, now that his arm was that of a dragon, he had no weakness. Issei gripped the cross in his gauntlet hand and heard his gear.

[Transfer]

Issei then looked to Rias and noticed her surprise of seeing him dressed in red armour, however there was no time, he only had 10 seconds more, in this form. Issei charged head first into the barrage of fire ball Riser was throwing at them. He used his armour hands to bat them aside until he was close enough to hit Riser. He brought his gauntlet fist back and slammed it into the stomach of the devil, who cried out as he doubled over. The punch had done serious damage thanks to it being invoked with the holy power of the cross. Issei noticed Riser backed up a few paces and looked at him.

"How? Such a punch shouldn't have done this much damage, wait what's that in your hand, is that a cross!"

Issei allowed the cross to be seen, he then advanced forward he only had six seconds left, he needed to put this creep down for good. What had pleased Issei was Riser wasn't regenerating. He bought his gauntlet fist back again and slammed into Riser face, the impact sent Riser crashing into a nearby tree.

"Impossible, you're a devil, how can you use the power of the church, unless, you sacrificed your arm didn't you! Do you know what you have done? That arm will never be the same again, you will be a freak of nature...Ahh" Riser felt gauntlet fist smash into his face again, and again.

Issei carried on punching Riser, over and over again, until finally his armour timed out, he then left the bloody mess that was now Riser sprawled on the floor. His face was swollen, several teeth had been knocked out, and his nose was gushing blood. Issei then stepped back and watched as Riser tried to crawl, but ended up falling. While this had been happening, Issei Sacred Gear had been boosting, and now it was at four boosts. Yusei aimed his gauntlet hand towards Riser and watched as an orb of green energy got bigger and bigger in his out stretched hand. Just before he fired the energy blast he heard Riser.

"Don't do this, you don't know how important this union is between us, You're nothing but a servant, you shouldn't mess with your betters."

Issei narrowed his eyes. "I don't care if this Union is good for devil kind, I only care about one thing and that is Rias. She doesn't want to marry you, and will not have you or anyone else force her to do something she doesn't want to do. Now say good bye to Rias, as this engagement is over!" Issei fired the energy blast at Riser, who cried out, and vanished in the green blast.

"Lord Riser defeated, Winner Lady Rias"

Issei fell to the ground, that had taken a lot out of him, but at least he had protected Rias, Issie suddenly found himself embraced by Rias who was hugging him and holding him to her chest, he heard her crying and felt the tears on his clothes.

"Thank you Issei, you did it, you saved me." Rias carried on holding until Issei as the world around them suddenly vanished until they were stood in the middle of an arena, which was filled with spectators. Rias and Issei broke the embrace and heard chatting until finally the arena was bought to silence by someone standing in the royal box. Both Rias and Issei looked up to see Sirzechs ready to address the spectators.

"Ladies and gentleman of the underworld, the winner of this rating game, is Lady Rias Gremory, and as she has won, I declare the engagement with house Phenex be voided, and revoked. Now I believe Lady Rias and her peerage have other places to be."

Rias closed her eyes in relief, it was finally over, she had won, which meant she didn't have to marry that slime ball. More importantly Issei had been the one to take Riser down and to protect her. However her eyes were now drawn to his arm that was now red and scaly.

"Issei what happened to your arm!" Rias lifted and examined it, she then felt, it, the arm was hard, red and had scales.

Issei sighed. "Rias the only way I could save you was by sacrificing a piece of my body to Draig, that was why I could use Scale mail, in exchange for the temporary power I had to give up my left arm. But I would do it again, if it meant saving you…." Issei was suddenly cut off by Rias lips on his, wow was Rias Gremory actually kissing him, this was awesome.

Meanwhile in the Hospital

Yusei and the girls was watching the moment on TV, who knew devils watched TV, let alone had their own TV network. Yusei watched as the camera zoomed in on Rias and Issei, kissing.

"Nice Job Issei, it seems I was right to leave Riser to you."
