''Blacklight''-Thinking

{Boost}-Ddraig

*Flashback*

Chapter 1 : Code Name : HADES

''Why am I here?'' Issei Hyoudou the host of the {Boosted Gear} and the new Red Dragon Emperor said out loud as he look blankly at his ceiling of his room as he try to remember the last thing he was doing.

He was in a [Rating Game] between his Buchou and [King] , Rias Gremory and Raiser Phoenix. The area were they were fighting at was a replica of the school that he goes too. Their base was at the old school building, and he was running through the battlefield with his fellow devil Kiba Yuuto and Koneko Toujou the charming [Knight] and the cute white hair [Rook],they were aiming towards the enemy base which was the new school building and he even got his {Boosted Gear} upgraded.

But then one by one his friends had fallen in battle, Koneko fell, then Kiba, and then Akeno Himejima, the black hair [Queen] of Rias, the strongest of the group...fell.

Finally he remember that he was on the roof where Rias and Aisa Argento, the [Bishop] of the group and they both were battling Rasier and he finally got up there and try to fight Raiser until everything went black.

He suddenly shot up from his bed as he suddenly remember what happen as his mind went into overdrive with questions like what happen?, Did they win?, The outcome?, and Did they beat Raiser!?

''It seems you are awake.'' A voice said as Issei turn to see the silver hair maid of the Gremory family, Grayfia Lucifuge.

''Grayfia-san? What happen? Did we win!?"

''Raiser-sama had won the match. Rias-ojiusama resigned.'' She answer.

''FUCK!'' Issei had shouted in his head, he was angry, but not a Rias or at Rasier...Ok maybe a little bit. But he was mostly angry at himself for being so...Useless!

Once again he couldn't protect the ones he cares about. Once again he acted so big, so immature and he couldn't do anything and went down in front of the woman that had given a second chance at life, the one he promise to protect and get stronger for her.

Once again...He fell.

Issei couldn't stop himself from crying. Even if the silver hair maiden was right next to him, he couldn't stop crying, not because he was sad, but of frustrated. He felt so shameful of himself.

Weak.

Pathetic.

''Currently, the engagement party for Ojiu-sama and Raiser-sama is taking place. Its at the assembly hall in the Underworld that was prepare by the House of Gremory.''

''Where are Kiba and everyone else?''

''They went to escort Ojiu-sama. The only ones not there are you Issei-sama and Asia-sama.''

''Wait Asia? How come she not there?'' He ask in a low tone.

''Due to Rias-sama's wishes, Asia-sama and I myself had stayed here of taking care of you Issei-sama, She is currently getting you a new towel. She answer as she saw Issei nodded his head grimly. It look like he made his master worry about him once again.

''Can't you come to agree to this?" She suddenly ask as he look up at her, leaving him speechless for a moment.

''No I can't agree to this. Never.'' He said in a angry tone.

''You know that Rias-ojiusama obeyed the family's decision.''

''Fuck that! Rias should be able to find her own lo-'' He has snap as he thought that Rias didn't want to have this marriage engagement, she wants to find her own person to love, that night when they had that talk about the power of the Phenoix, he would live and fight for her...He wanted his Buchou to be happy and live happy.

''Fufufufu.'' Grayfia started to laugh a bit. This was the first time he had ever seen her smile before and he though she look beautiful with a smile like that.

''You are a very interesting person. For a long time I have seen many Devils, however it is my first time seeing one like yourself who shows what you are thinking with your face, and acts accordingly to what you believe in. My master Sirzechs-sama was watching your effort in the battle against Raiser from another place and said you were ''Interesting'' you know?'' Grayfia had then took out a piece of paper out of her pocket that had a magical-circle on it. ''This magic-circle allows you to teleport to the engagement party of the House of Gremory and the House of Phoenix.'' She had told the [Pawn] as he was speechless again while he took the piece of paper from her hand.

''I also have a message for you from Sirzech-sama for you.'' She pause as her face turn serious again and spoke in a serious tone. ''If you want to save my sister, barge into the hall room.'' That what he said. There also another magic-circle on the back of the paper. Please use it when you take Ojiu-sama for I am sure it will be use to you.''

Issei didn't know how to respond to the silver maid as she teleport out of the room in a magic-circle as he was left in his room.

Issei immediately got up from his bed and went to find something to wear. He saw his school uniform that was folded neatly on the table, probably Grayfia that had did that and prepare it for him when he wake up as his last one was torn apart and destroy from the [Rating Game].

But before he was about to grab the school uniform he had another idea as he went to his closet and began to search for something that he had wish to put behind him and after a few seconds of looking he had found what he was looking for.

Issei had pulled out a silver briefcase that look like had a bio-metrics scanner on it and it had the words 'BLACKWATCH' on it as he was nervous just by looking at it, and just when he was about to put his hand on the scanner he heard a voice.

''Issei!'' Asia had return with a towel in her hand and a bucket of water but drop them to the floor as she ran towards to her friend and started to cry into his chest.

''Thank god.'' They both felt pain but it stop immediately as Asia continue to speak. ''I'm so glad your ok, you been asleep for two days and I thought you wouldn't wake up and...'' She kept crying into his chest.

Issei try to calm her down while patting her head with a soft smile on her face. He was a little surprise that he had been sleeping for two whole days, he had never pass out that long before.

''Asia, listen to me. I'm going to get Buchou back now.''

''!'' Asia look up at him as she was surprise by what he just said and immediately knew what he was about to do.

''It's not... To celebrate is it?''

''No it's not, I'm going to get Buchou back, beside.'' He said as he show her the magical-circle. ''I have a way into the engagement party.''

''Then I'm going to!'' She said without a second thought as she try to put on a serious face.

''No. You can't you have to stay here.''

''No I don't want to! I know how to use my demonic powers now and I don't want to be protected anymore!'' Asia had grab his hand and squeezed it strongly.

''No. You will stay here Asia. I will bring back Buchou, Its alright I'll beat Raiser up and I-''

''It isn't alright!'' Asia had raise her voice with mixture of crying as there was tears going down her face from her green eyes that were full of sadness. ''You will get bloody again, battered, and mushy again...Are you going to go through the pain all over again?'' She ask as she was still crying. ''Please I don't want to see you like that again.''

Putting on a smile Issei pattered her head again and wipe her tears away from her cheeks and look into her eyes.

''I won't die. I promise. Remember when I was still alive when I saved you? That's why I will not die. I will live and I promise to you that I will bring back Buchou and will stay with you and everyone from now on.'' Asia nodded as she heard this.

''Then promise me something.''

''What?''

''Promise me that you will bring Buchou back and will still be alive after.'' She said as she had a smile on her face.

''I promise.'' He said as he saw how happy she was, He turn around and put his palm on to the hand scanner as it too a few seconds then a beep went off as the locks on it open and when he look inside he saw a veil with some documents that had the words 'Project : HADES' on them as the inside of the veil was a black liquid that had some red smoke around it as it was moving around like it was alive inside.

After letting out a loud sigh, it had been a long time since he had seen this and he really wish that he would put this behind him and reach inside and pull it out and once he did Asia was some what surprise to see this.

''Issei what is that?'' She ask as she saw the black liquid move around inside the veil.

''Asia...This is something that I promise to put behind me along time ago and wish to never use it again.'' He softly said as he turn and look at the former-nun.

''I need you too leave the room for a few moments please.'' Issei had ask as Asia didn't want to put once she saw the look that Issei was giving her she left and shut the door behind her.

A green glow appeared on the back of Issei left hand. {Are you sure about this partner?} Ddraig the Red Dragon Emperor had ask to his current host as Issei look at the veil in his hand.

''I'm sure.'' He said as he smash the veil in his hand.

In the Underworld...

Issei was teleported to an unfamiliar place when he use the magic-circle that Grayfia had given him. The brunette began too look around as there were candle's on the walls showing the way and found two giant door in front of him that was open.

When he look inside he saw a large group of Devils who were all dress up all having a good time, which look like one of those high-class parties that he had seen in those movies he had saw.

He had scan the room and found some familiar face and see Kiba, Koneko, and Akeno all dress up as they had sad look on their face.

He look around again, then he stop as he saw familiar crimson hair.

He had find his master that that her crimson hair tied up and was wearing a beautiful white wedding dress.

''Buchoooooouuu!'' Issei had yelled out as everyone in the room had turn towards the door way where he was as Rias, Akeno, Koneko, and Kiba had all look at the door way and had surprise look on their faces. The bastard Raiser was also looking at him while he was beside Rias as he was wearing a white version of his outfit that he wore during the [Rating Game].

''Ise!'' Rias had said in shock as she and everyone in the room look at the [Pawn] in surprise as they saw him dress in a black leather jacket with a red collar on it with two white strips around both arms and if you could take a look on his back, you could see a red tribal symbol on his back that look like two dragons. (AN : The Alex Mercer symbol.) He was also wearing a crimson red hoodie with the inside black and a white dress shirt under the hoodie, He also had dark blue jeans with black combat boots and black leather fingerless gloves.

Issei had took a deep breath as he shouted to everyone in the room to hear. ''To all High-Class Devils in the room and Also Burchou's brother, Maou-sama! My name is Issei Hyoudou from Kuoh Academy! I have come to take back my Burchou Rias Gremory-sama!'' Issei had yell out to for the entire room to hear him.

Without a care to them, the leather jacket boy began to walk towards his master.

''Hey! Stop right ther-'' A guard try to stop Issei, and as he reach him, everyone in the room was surprise to see Issei pick up the guard by his neck and threw him into a near by wall and knock the guard out as he flew out of the wall.

Everyone that watch the [Rating Game] between Gremory and Phoneix were surprise and shock as they saw the monsterous strength that the [Pawn] of Risa has displayed like that, unlike the one who was battling the peerage of Raiser without his perverted tactic.

He then walk over to Raiser as he scream into his right into his face. After being around a old friend of his for a long time who who use these kinds of words when ever he was angry and he had influence Issei and started to use the same way use the same language that Issei would now use whenever he angry.

''Rias doesn't belong to you! You little cock-sucking mother fucker!'' Issei had scream in Raiser face as his eyes were glowing red, Raiser and everyone was a lost for words since Rias and her peerage had never heard Issei curse like this before.

''What is the meaning of this Raiser!?''

''Lady Rias what is the meaning of this!?''

Some devils were saying in the room as they saw what was going on and before they could say anything else a man with the same crimson hair like Rias step in and said loudly with a smile on his face.

''This is an event that I have set up.''

''Oni-sama?'' Rias had called out in surprise.

''I wanted to see the power of the Red Dragon, So I ask Grayfia too bring him here.''

''Sirzech-sama!? This is irresponsible to do something like this!'' A random devil had yell.

''Hey! Shut the fuck up or I'll shut it for you Bitch!'' Issei had yelled out as he glare at the devil with his red glowing eyes, as everyone was surprise by Issei language.

''It should be fine. The [Rating Game] from last time was very entertaining. But it was a bit of a disadvantage for my little sister who had no game experience to face against Raiser who is a prodigy from the House of Phoenix.''

''...So Sirzech-sama, your saying that the game wasn't fair?''

''No, no, not at all. If a Maou such as myself is saying such things, then I will make all old nobles look bad. The connection between the High-Class Devils is important after all.'' Sirzechs said with a smile.

''Then Sirzechs. What do you want to do about it?'' Ask another crimson hair man that look a little order then Sirzechs. Issei had wonder if everyone in the Gremory family all have the same shade of crimson hair.

''Father I want to make my cute littler sister engagement party into a flashy one. Dragon vs Phoenix. Don't you think it's the ultimate event? To stir up the party by having a battle between two legendary creatures. Besides there aren't any entertainment which can sure pass this.'' The Maou said as he look at his father.

''Sorry to disappoint, but you aren't gonna see the power of the Red Dragon Emperor tonight.'' Issei had said in his head as he smirk to himself.

Everyone in the hall room became silence as they listen to the crimson hair Maou's words. Sirzechs then turn to look into Issei eyes.

''Anyway Dragon User-kun You have our permission.'' He then turn to Raiser. ''Can you show your power in front of Rias and I again?'' He ask as he saw Raiser put on a fearless smile.

''Very well. There is no way I can decline if Sirzechs-sama ask me. Raiser will show a last performance before getting married.''

''For fuck sake's, will you stop referring yourself as a third person, you prick.'' Issei said as he rub his face as Raiser got angry.

''Why you little lo-'' Raiser try to say until Sirzechs put a hand up and silence him before he turn to Issei as he and along with Rias and her peerage try not to laugh at what Issei said.

''Now then Dragon User-kun, what prize do you wish to have when you win the match?'' Sirzech said as all of the devils in the room beside Rias and her Peerage started to protest against this as once again Sirzechs had put a hand up to silence everyone in the room.

''He's a Devil, so we need something fitting for it since we are asking something for him to do for us. What will it be then, A peerage, a beautiful woman?''

After what seem like forever Issei had answer. ''Sirzechs-sama I want Rias Gremory-sama back.'' He declared to the crimson hair devil, and just when he was about to speak Issei cut him off and said. ''And Raiser peerage.'' Issei said as he shock everyone in the room by this, even Sirzechs was surprise by this as his eyes were widen.

''What!?'' Raiser scream out in rage.

''I understand why you wish for my sister, but why Raiser peerage as well?'' Sirzechs ask.

''Sirzech I don't want this battle just be a brawl to free my master from this engagement.'' He said as he didn't answer why he wanted Raiser peerage before he then glare at Raiser. ''I want this battle to be to the death.'' He declared as Rias, her peerage and everyone else in the room had there eyes widen.

''What are you saying!?'' Rias had yelled out as she look at her [Pawn] with fear in her eyes.

''Very well. This battle will be to the death and if you win you may take my sister and along with Raiser peerage with you.'' Sirzech had said as Rias turn towards her brother.

''Oni-sama!'' Rias had try to protest until she felt a hand on her shoulder and turn to see Issei looking straight into her blue-green eyes with a smile on her face.

''It's alright Rias, I won't die this time, I will win this for you and for everyone.'' Issei said as Rias had hug him closely as tears were going down her face.

''Please don't die.'' She whisper as Issei had a smile on his face.

Battlefield with Issei and Raiser...

The hall room were everyone was at was empty as everyone hurry to see the battle between Issei and Raiser.

The club members of the Occult Research Club were sitting in the same place were their [King] and along with her brother and silver hair maid were at.

On the other side the member of the House of Phoenix, were their relatives, their servants, and Raiser's sister and his peerage.

Both Issei and Raiser were on the battlefield as they were facing each other, as Issei didn't have his scared gear out, and that worry his fellow peerage members.

Raiser had a smug look on his face as Issei had a hateful expression on his.

''BEGIN!'' Grayfia had shouted as she called for the battle to begin.

Raiser who had his flames wings were out as he pointed a finger at Issei and gave him a crazy smile on his face. ''So you think you a Low-Rank Devil can kill an immortal Phoenix like me!?'' Raiser started to laugh like a madman as Issei reach for his hood as he put it on. ''You who's all of your skills are cracked. A sacred gear that keeps on doubling the power of the user, the {Boosted Gear}. Also it seems you have gain a new power that can transfer the multiple power into an object or allies.''

''So?'' Issei said as the hood made a shadow that cover his eyes and only showed his mouth.

''So!? You're useless without your fellow peerage members to fight along your side!'' Raiser had started to laugh confidently.

''Ise.'' Rias had said as she had a doubtful face, looking at the boy who came to win the freedom that she couldn't get.

''Rias!'' Issei had called out as he look at her. ''I will win this for you and for everyone! I will crush anyone who dares make my friends cry, I will kill who ever lays a finger on you and our friends, I will even fight God and Satan themselves if that what it takes just for you to be free and live happy!'' Issei had said out loud as everyone watching the battle were shock by this, as a Low-Class Devil like himself, would even declared to fight God and the Morning Star themselves! Just so his master could be happy!? And they all look at his face to see how serious he was when he said all that.

''I will even become a monster, just to keep you and everyone I love safe from people like him!'' Issei had shouted as he pointed a finger at Raiser, who was equally shock by what Issei is saying as Rias was crying and sobbing as she heard all the words her [Pawn] is saying, while Kiba, Koneko, and Akeno were speechless as they saw the Issei they had got to know, change into a completely different person from the perverted person they have gotten to work with.

''!'' Everyone had a shock expression on their faces as they saw what look like black and red tendrils were around Issei arms as they were changing into razor sharp claws that replace his hands as they form spikes on his shoulder and around his arms had a lava color glow on them. (AN : Think as them like James Heller claws when fully upgraded.)

''What is this!? Is this a trick!?'' Raiser had yelled out as he look at Issei Claws.

''No this ain't a trick, you fucking cunt!'' Issei yelled as he sharpen his claws with sparks of fire came off of them. ''This is something from my past that I wanted to put behind me.''

''What the hell are you Hyoudou!?'' Raiser had scream out as he look at Issei as he had a smile that look like a predator would use when hunting their prey.

''I am many thing Raiser, a monster, killer, a bio-weapon, devil, dragon, and [Pawn] of Rias Gremory, but now I'm not just Issei Hyoudou.'' He said as his eyes began to glow red. ''I have a code name.'' Issei look like he was about to get ready to jump. ''And my code name...Is HADES!'' Issei yelled at he let out a roar as he jump at Raiser with his Claws. As everyone is about to witness the power of the Blacklight Virus.

The Human World at Japan air port...

Back in the human world were everyone who were getting of their planes were now either leaving or going inside the air point to catch their plane, Out came a group of Four. One was a man that look to be African American and who had a buzz cut hair style with a small scar on the left side of his eyebrow and brown eyes, He was wearing a black leather jacket with some red flames on the sleeve and a red tribal symbol on his back, He was wearing a black hoodie with the inside red with a pair of cargo pants and combat boots and also a pair of leather fingerless gloves.

The second one was a Caucasian woman, who had the same crimson red hair like Rias,with cold blue eyes, wearing a short white leather jacket, with a grey jumper top with a black scarf around her neck, wearing a pair of black trousers for women and black ankel boots.

The third one was a little African American girl who looks to be 10 years of age with the same brown eyes like the man of the group with long dark hair that reach the top of her back, she was wearing a black hoodie with a white t-shirt and blue jeans with black sneakers.

The little girl was holding a baby that look to be Japanese and asleep that was wrap around a blanket, but if you look closely you could see that the baby was a girl who had brown hair like a certain Pawn, and as she open her eyes for a few seconds, you could see a pair of Chocolate brown eyes.

''So this is Japan?'' The African American man said as he look around the airport.

''Yes, I been here before one time and its lots of fun.'' Said the Caucasian woman as she smile.

''Dad when can we go see Uncle Issei?'' Ask the little girl as see look at her father.

''Tomorrow Maya, Right now I bet he asleep.'' The man said as he look at his daughter that is know as Maya now.

''I wonder if he ok?'' The older woman said out loud.

''Dana, If he can survive being in a city full of infected creatures and take down BLACKWATCH with Mercer Evolved and Mercer himself, then I'm sure he fine.'' The man said to the know name Dana as he put a hand on her shoulder.

''Yeah I know James, I know.'' Dana smile at James Heller as the group of three look around the city.
