[] Sacred Gear talking

Outside Church In Kuoh

Rias and the group appeared in a small clearing a few feet from the church, however they wasn't alone. Up in the tree was sat a girl who looked to be around twelve she was dressed in a black and white dress, she smiled down sweetly, revealing two pointed teeth.

"Well, well, looks like Raynare was right on the money, she said we might have some company, tonight." The girl suddenly produced a spear of light in her hand. "I can't let you guys go any further, if I do Raynare will kick my arse."

Rias looked up at the girl. "You do realise who your talking too right, little girl. You may be a Fallen Angel, But I am the sister of the current Lucifer. My name is Rias Gremory and this town is under my protection, I will not have some snot nose little brat, tell me what I can and cannot do, in my town!" Rise eyes glowed and demonic energy began to form in the palm of her hands. "Now we can do this the east way, or the hard way, what will it be?"

The Fallen Angel looked down, and noticed she was outnumbered, not to mention she was now staring into the eyes of the current Lucifer sister. Where the hell was that back up, Just as she was about to surrender, two of her colleague suddenly appeared. The girl smiled in relief. "Well little devil, it seems the odds are even now."

"How about I unbalance them a little then" Every one attention was suddenly drawn to Yusei, who was walking towards Rias and the others, with his Sacred Gear on show. "Rias why don't you take the others and go rescue the girl, me and Akeno can take care of these three."

Rias was surprised, where the hell had all this confidence come from. She could see a look of determination on Yusei face, something had changed. "Okay, Kiba, Koneko, Issei, come with me, good luck you too." Rias and the others were preparing to leave when a spear of light was thrown towards him, however as it approached, it was blocked by a bolt of lightning. Rias looked to Yusei hand his gauntlet arm was raised and she could see static electricity surrounding it. Before any more spears were thrown, Rias and the others ran towards the church, just leaving Yusei and Akeno to take out the Fallen Angels.

Yusei stepped close to Akeno and noticed she had already changed into her battle attire. Yusei counted the three Fallen Angels, and noticed they were closing in on them. "Akeno, can you create a barrier around the area, I don't want any of them to escape."

Akeno looked to Yusei and smiled. "Sure." Akeno then used her demonic power to create a barrier around them, she was still wondering what Yusei plan was, they were still outnumbered, however her eyes widened as she heard Yusei shout out.

"Thunder Dragon Armour!" Akeno watched as a red blast of energy left Yusei Sacred Gear and then swirled around him. Eventually it took the shape of a dragon, and, static waves were dispersing from the dragon.

Flash back

Yusei was sat in his room looking at his Sacred Gear, he wanted to know more about it and what it could do. Yusei decided to call Slifer and watched as the Jewel blinked green several time. He then heard the voice of Slifer.

[What do you wish to know Yusei?]

Yusei looked down at the gauntlet, "I was just wondering what abilities I have at the minute. I remembered that you saved me that night from the Fallen Angel, and this Gauntlet dispersed a red energy blast that swirled around me. It felt like some type of shield, and I was just wondering if I had access to this ability, or was it something you just did to protect me."

[The ability you are referring to, is known as Thunder Dragon Armour, its an ability that allows you use my power for a short period of time. As for your other question, yes you have access to this ability, and at present it is the only ability you have access to, until you unlock the Trinity Gears full potential. This gear consist of a number of seals that you will have to break, each time you break a seal, you will gain a new ability.]

Yusei frowned. "So what you're saying is I could have used that ability against that maniac Priest yesterday night, why didn't you tell me?"

[You never asked till now, you just used your gauntlet for defence.]

Yusei groaned. "Well thanks for letting me know, at least now I might be some real help to Rias and Akeno."

End of flashback

Yusei noticed the surprise on Akeno face. He turned and smiled at her. "Surprise, I found out from Slifer that I can use this ability, now lets show these Fallen Angels a real Thunderstorm!"

Akeno floated into the air and then formed a yellow magic circle in the sky, she pointed her fingers skywards and from the circles lightning began to rain down around the area on all the Fallen Angels. Yusei wasn't going to be left out, he was now fighting the Fallen Angel who had tried to kill him. "Pay back time you bastard!"

Dohnaseek charged towards Yusei, and started to produce light spears, he threw them towards the boy only to see them smashed on impact with the static armour the boy was wearing. Dohnaseek noticed the boy looked up and smirked.

"My turn!" Yusei charged towards the Fallen Angel, punching away the light spears being thrown his way, as he charged forward he heard the voice of Slifer.

[Remember Yusei, you only have so much time in this form, once time runs out, you will go back to your regular self. You have 30 seconds remaining in this form."

Yusei smiled that was plenty of time. Yusei was now a few feet away from the Fallen Angel, he extended his gauntlet in front of him, and heard it talk.

[Absorb!"]

Yusei watched as the Fallen Angel cried out as his power to produce light spears was absorbed into gauntlet. Yusei smiled and then willed a spear to appear, as he did, a light spear formed in his gauntlets hand. He noticed Dohnaseek was recovering from being drained, however Yusei wasn't going to give him a chance. Yusei threw the light spear and watched as it pierced through the Fallen Angels wing, forcing Dohnaseek to cry out in pain.

Akeno was busy with the other two Angels, who were now smoking on the clearing floor from being hit with her demonic lightning. She bit her lip as she watched Yusei beat the hell out of the Fallen Angel, she felt her body heat up, and started to touch her breast, God he was so hot, when he was kicking arse! Akeno was getting so turned on that she even began to touch herself below. She had never been turned on so much in her life. "

Meanwhile Yusei was running out of time, however the damage had been done, Dohnaseek was now a complete mess laid out against one for the trees. His wings were bleeding from being pierced by his own light spears and his face was swollen from the beating Yusei had given him, using his gauntlet fist. Yusei suddenly felt his power disperse he looked up and smiled to Akeno, pain really did turn her on.

"He's all your Akeno." Yusei grabbed hold of Dohnaseek and then pushed him into the centre of the clearing, where the other Fallen Angels were laid out. He looked up and saw Akeno wink, before she summoned another circle of magic and unleashed several bolts of lightning onto the three Fallen Angels, their screams echoed around the clearing, until nothing but Ash and black feathers were left.

Yusei only had time to look up, before Akeno had pushed him down onto the clearing, and attacked his lips with hers. Yusei kissed her back, he didn't care that they were laying in the middle of the remains of three Fallen Angels. Hands started to roam over each other bodies as the kiss deepened further. Yusei felt his hand grabbed and placed on Akeno breast, he groped and squeeze both of them, causing Akeno to moan with pleasure. Unfortunately they were stopped from going any further by a voice.

"Rias wanted me to check up on you two, however it seems you have things well in hand." Kiba turned his head away, from the display now going on in front of him. He noticed Yusei and Akeno quickly stood up and brushed down their clothes, much to Kiba amusement.

Meanwhile inside the Church

Issei, Koneko and Rias were fighting their way through the Exorcist, which had gathered around Asia as she was chained to a cross at the front of the Altar, Rias had already killed a lot of them, but still more remained. Issei noticed they were all stopping them from reaching Raynare who was just finishing the ritual. Issei heard Asia cry out, and then looked to see her Sacred Gear, leave her body and float into the hands of Raynare.

"Finally I've been after this power for years and finally it's mine!" Raynare placed the two rings against her chest and then absorbed them. Her whole body then gave off a dark green aura."

Issei noticed Rias and Koneko had now created an opening between the ranks of Exorcist, Issei cried out as he charged up the stairs, however as he saw Asia on the cross, he fell to his knees. He had failed, it hadn't been able to save her. Issei watched as Raynare mocked him.

"How tragic, you're were so close, and yet so far. I say you have about five minutes left before she dies, I guess I can allow you to say goodbye." Raynare then waved her arms and the chains that was binding Asia fell apart. Issei caught Asia in his arms and looked down at her.

"Asia, I am so sorry, I couldn't save you." Issei noticed Asia opened her eyes, he could see the life draining from them. He had to get her out of here, however it seems Raynare had other ideas. Issei at the corner of his eyes saw the glow of a light spear.

"I think I have given you enough time to say goodbye, but hey, least you both get to die together." Raynare stabbed her Spear towards Issei only for her to be blasted back by a swirl of energy. "Hey what the hell!" Raynare eyes slowly widened, as Issei was stood up, facing her, his head lowered. She heard his voice, and it really freaked her out. The boy should have been broken, where was he getting this strength from.

"You will pay for what you did to Asia, I will make you scream for death when I'm done with you. Not only did you toy with my emotions but you sacrificed Asia, someone so innocent, just so you could take her Sacred Gear, you're a monster, and monsters have no place in this world. Raynare your twisted game ends here! Sacred Gear boost!" Issei watched as his gear suddenly glowed, he heard voice coming from his arm.

[Explosion!"]

Issei watched as his Sacred Gear changed before his eyes. From the front red metal claws exploded out, and from the back, red metal, with sharp spikes began to wrap around his arm until half his arm was now covered by a red Gauntlet.

Rias smiled as she looked up to the altar, she had been right, Issei was the wielder of the Red Dragon Emperor, things were about to get a lot more interesting. "Do it Issei, teach that bitch a lesson, show her what happens to those who dear cross the house of Gremory! And the power of the red Dragon Emperor."

Raynare face was white. "Red dragon Emperor, no, that's impossible, it can't be, the boosted Gear, one of the weapons that can kill God, impossible." Raynare heard the Sacred laugh.

[So much for calling me a double critical. I am the red dragon Emperor, the force that even God fears! You have taken something away from my host, and now he will take something away from you. Namely your life! Boost, Boost, boost!"]

Raynare couldn't believe one of the Sacred Gear that could kill God was in the hands of a child, Impossible. Raynare knew she had to get away, however she cried out as she was engulfed by a Bright red light beam fired from Issei Sacred Gear. She screamed as her very being was torn apart, until all that was left of her was a few black feathers. Amongst the feathers was two silver objects that were now glowing.

Issei suddenly fell to his knees, and looked to his Sacred Gear, had he really just killed Raynare? Issei had no idea his Sacred Gear was that powerful, where had all that energy come from, and what was that voice? It was then Issei felt the hand of Asia, he turned to see her eyes were half closed.

"You did it Issei, you protected me just like you said you would. I am so lucky to have friend like you."

Issei held onto Asia hand tightly and turned his head to see Rias and the others had joined them. He noticed Rias had an evil piece in her hand. Issei turned back to Asia, understanding that the only way for Asia to live, was for Rias to make her a servant to House Gremory. Issei looked down and noticed Asia eyes were now closed. She had gone, left this world for a new one. Issei felt Rias hand on his shoulder, he looked up at her, tears in his eyes.

"Bring her back please, she was to innocent to die like this. She deserve a second chance, please save her."

Rias smiled softly. "I was planning to anyway Issei, now I need you to step back." Rias watched as Issei stepped back, Rias approached the lifeless body of Asia and laid on her chest her Sacred Gear and a Bishop evil piece. She then stood up, and held out her hands. A magical circles suddenly appeared under the body of Asia. Rias then began to chant.

"In the name of Rias Gremory, I call to Asia Argento, hear my command, Return thou soul from the valley of death to the human realm, Raise once more as my demon servant, Rejoice for you have been given new life. Wake as my healer and Clergymen!" As Rias finished chanting both evil piece and Sacred Gears began to glow and absorb into the body of Asia. Rias then stepped aside and noticed Issei was on his knees, next to Asia, he cradled her in his arms and waited.

Asia suddenly opened her eyes, and stared into the face of Issei, she smiled shyly, however her eyes widened as she felt Issei pull her into his chest, she could feel tears falling on her gown. "I will never let anyone hurt you again, I promise."

Rias smiled down, at the happy reunion. "I don't make a habit of reviving people Issei, but you're were right, she was too innocent to die, especially like that. Beside her power will be useful and we could really do with a healer in this family."

Issei looked up to Rias. "Thank you Rias, Thank you."
