What's up my dudes! I give you the third chapter and I apologise for the unorthodox writing style of this chapter. Again thank you everyone for your support; I understand that I'm overstating this but it really warms my cold as marble soul to see so many reading my work!

With that, on to the story!

Disclaimer: Again, I don't own Fairy Tail or High School DxD.

FIGHT!

"ISSEI~! NOOOOOO~!"

Issei was held up by the neck, beaten, bloody and broken; like a ragdoll, with virtually no life, he fumbled at his opponent. Riser sneered and threw Issei down the the roof of the new office building. Issei grit his teeth as he rolled to a stop against the eaves, his voice unable to scream out in pain.

"Rias, my dear, won't you stop and surrender? Can you bare watching Riser beat your precious pawn to a bloody pulp?"

Rias didn't respond, to caught in figuring a way out, a way to stop what was happening. Issei saw the despair in her eyes, he didn't want her to feel sad, it was his job as her pawn to serve her!

"Fuck You! Riser, Ya Creep! Come and finish me off like a man!"

Riser sneered, "Looks like Riser will have to teach you your place!"

Riser walked towards Issei casually, there was no need to move quickly when, he had practically already won. He grabbed Issei by the neck and slammed him into the roof, Issei coughed up a crimson liquid, adding to his already bloodied shirt. Riser stepped back and summoned a small fireball in his hand. As he was about to chuck at Issei's head, he was tackled.

"I Surrender! Just don't hurt him anymore!"

Issei faded from consciousness as he heard those words, he saw her tears as she jumped at Riser.

"Rias Gremory surrenders; Victory by Lord Riser Phenex. Game End."

"Come on! What was that fight?! That was disgraceful for the sister of a satan,"

"Yeah, Riser really won that one easily,"

These comments passed over Natsu and Sirzech's head where they had stood watching the rating game.

"You remember my favour right?"

"Of Course. Anyways I'd still do it even if it weren't a favour."

"That's good to hear."

Natsu and Sirzechs gripped each others hands as an understanding between good friends. They both wore crimson suits, Sirzechs in a lighter red akin to his hair, with a white undershirt and oxford shoes. Natsu wore a red suit with orange and yellow as complementary colours, the suit rippled and moved giving the effect that Natsu himself was on fire. He wore an obsidian stud with an embedded ruby, adding to his overall mature but young look.

"I guess it's time for my party?"

"It sure is, Natsu."

Natsu and Sirzechs walked out of the room with enough deadly grace to shut up the comments being made about the rating game and command them to watch as the two left the room.

"WAKE UP!"

"Wah!? Who's there?!"

Issei stared around his room, looking for the source of the oppressing tone.

"I am the dragon that resides in your arm! Ddraig, the Red Dragon Emperor!"

"Woah! I didn't realise there's a freaking dragon inside my own arm!"

"Now that you realise that, Why don't you stop gawking and look at the situation your in!"

"What situati-! Rias! I have to go save her, right now!"

"Now hold on! With what power?"

"I-I guess I'll just boost even more times than before!"

"Idiot! As if that would work against Riser Phenex, don't you remember he almost instantly regenerates! Also how would you get to the underworld in the first place, hmmm?"

"..."

Issei looked aghast, and stared blankly at the wall. His saviour came in the form of a bright white flash of light as a familiar french maid came into appearance.

"Grayfia! What are you doing here?"

"Lord Sirzechs told me to give you this. It is an invite to Lord Riser and Lady Rias' engagement party."

"Why would I want this! I don't need to see her be engaged to someone she doesn't love! I need to save her!"

"Lord Sirzechs said that all parties should be there, supporters and otherwise."

With that Grayfia left without another word. Issei realised what had happened and finally knew what to do.

"Hey Ddraig, could you make me a deal?"

Riser stood in front of a large crowd of devils dressed elaborately.

"Riser has come to thank you all for coming to my engagement party! This union represents the joining of the Phenex and the Gremory! Riser would like everyone to see my bride for this union, Rias Gremory!"

Rias appeared on stage in a pristine white wedding gown. The dress didn't overshadow Rias' own beauty though, the dress complemented her perfectly, the white contrasting her red hair and emphasising her smooth white skin. She walked towards Riser and stood next to him. He draped his hand over her shoulders, Rias' couldn't shy away from him though, since in doing so it would upset the distinguished devils before them. O how she wished that she was engaged to anyone other than Riser. Her thoughts turned to Natsu and the kisses they shared, any devil watching closely would notice a light shade of pink appear over her cheeks.

"Riser would like to proceed to the wedding as soon as possible, and you are all invited!"

Sirzechs moved forward to say something.

"Before that, are there any objections to this marriage?"

"YES!"

The word rung around the room, implanting shock in the audience. They were unsure how treat the arrival of an opposition.

"Who dares speak to Riser!?"

"I, Natsu Dragneel, the fire demon: END"

Natsu emerged from the roof, his descent slowed by his flames, his suit rippling and appearing as fire. The audience split in two, forming an aisle from Natsu to Riser. Rias was shocked, her wish had come true to some extent. Natsu walked up to the stage as Riser began talking again, "Don't you understand that rabble shouldn't offend a union between high-ranking devil houses!"

"All I see is a union between a roasted chicken and a goddess."

"You bastard! You dare call the noble house of Phenex a-a ROASTED CHICKEN!"

A member of the audience jumped out at Natsu and tried to attack him. Notice the tried. Natsu grabbed the offenders face and slammed him into the ground, shattering the floor. What was even more astounding to the members present was that there was no magic used in that one attack. One physical attack against a member of the Phenex family supporters. It was clear that no one could believe their eyes.

"Ah, the entertainment I planned has arrived!"

"What is the meaning of this onii-sama?!"

"I planned for a battle between my newest addition and Riser, It shall be a fight of the century! Third Son of the Phenex family, a family peerless in their use of fire, and Natsu Dragneel, self-proclaimed fire demon!"

There were murmurs around the crowd, if Sirzechs had made a new addition to his peerage it would have to be a strong player, meaning that someone might actually beat the Phenex's regeneration.

"You talk a big game for rabble, Riser accepts this fight and will shove this insolent in the dirt!"

"Fine by me, roasted chicken. However, let's make this more interesting, hmm? How about we make a little wager of giving me Rias Gremory as my fiancé!"

Rias exploded. She had never considered marriage with Natsu and to see him make the first move blew all her fuses. Sirzechs smirked. His plan was going without a hitch.

"And what will happen if you lose?"

"I'll prostrate myself before the Phenex family and beg for forgiveness!"

The audience gasped; pride was a matter of utmost importance to devils of any rank. And to throw away all pride and literally beg for forgiveness was unthinkable!

"The fight shall take place in fifteen minutes!"

The crowd cleared eager to see this fight. Riser attempted to get some form of good luck from Rias in the form of a kiss, but as the crowd was leaving Natsu had made it to the stage and picked up Rias, bridal-style, snatching her away from Riser's claws. Riser hmphed in apprehension and left without another word, but plenty of disdain and scorn.

"Miss me?"

Natsu grinned at Rias. She couldn't believe that he had actually come to save her from Riser's clutches, she thought she was dreaming at first and thought that there would only really be one way to prove it was real. She pulled his hand down to hers, their lips clashing once again.

"Ahem! Natsu you must get ready for your fight."

Rias let go of Natsu, her face as crimson as her hair, Natsu nearly dropped Rias at the sound of Sirzechs voice behind him. He let Rias down, as Rias' peerage rushed up to the enveloped Natsu in hugs and Akeno enveloped his head in breasts. Natsu had completely forgotten they were there in his grand entrance(A/n: AHEM! Fourth Wall Break.)

"Natsu! Why does Rias get all of your kisses?"

Asia's cute jealousy was exacerbated by her equally adorable pout.

"I agree Rias, isn't unfair to keep Natsu to yourself?"

"Who said I was keeping him to myself?! I wasn't the one who proposed! He was!"

"Oh, that's right! He basically said he'd marry you if he wins. Congratulations on marrying someone you like!"

"I-It's n-n-not like that!"

Natsu took this time to leave and get ready for his fight. Seeing them act so normal in an irregular way was more motivating than any words anyone could offer. He changed out of his suit and into his combat gear, an open black sleeveless jacket and white baggy pants fastened around mid-shin. The fairy tail tattoo emblazoned on his right shoulder and the tartaros keys emblazoned on his other. He warmed up his hands and pulled his hair back and out of his eyes. He smiled in the mirror.

'Narcissist.'

"Shut up END."

"Ya ready?"

"I'm always rearing to go for a fight."

With that Natsu and his resident demon walked out of the changing rooms and into the arena. Riser decided to make a gaudy comment about cowardice and showing up, but Natsu tuned him out.

"Yeah Yeah, braised chicken, are we gonna fight or no?"

Riser fumed.

"If we are to fight, than I'm gonna give you a handicap, I will not move for an entire minute, if you can hurt me I'll play."

Riser exploded in rage, the fight began on that note and Riser took to the skies with his flaming wings, he summoned a demonic fireball into his hand and threw it at Natsu. Natsu, true to his word stood there and took it. The fire cleared to reveal no harm done. Riser gawked in his mind, but gritted his teeth physically. He knew that Natsu was playing with him.

"40… 39… 38… Time's ticking! 37… "

Natsu kept counting as multiple more futile attempts were made. Riser had to get serious and use his most powerful spell. He summoned a fireball to the tip of his finger and drew a pentacle in the sky.

"Let the flames of my blood, burn you and smite you into the ground! Infernal Rain!"

Thousands of fire balls flew out of the pentacle and struck Natsu. Natsu smirked at the attempt and noticed some cuts and wounds forming on his arms chest. The healed almost instantly, as an effect of END's programming.

"Tch. You didn't understand with the first one did you? If you use fire, it ain't going to work on me! So, you would've had a better chance if you resorted to more physical means such as this."

Natsu grabbed his arm and ripped it off of him in a flash, Rias and her peerage looked on in horror, why would Natsu hurt himself, by ripping his own arm off! Natsu dropped the arm as it dissolved into fire.

"Then again it would have no real effect."

Riser's face turned from smug to shocked as Natsu's arm regrew, in the same manner that he regenerates his own limbs.

"How the fuck can you do that?! That's exclusive to Phenex family members!"

"When I said I was a fire demon, I meant that I am a demon of fire, made of fire, and having absolute control over fire. Meaning that any fire spell there is in the world, I can use it! Thus I will end this fight with one fire attack."

"Quarter First Origin, Reduced Beam."

Natsu point his finger at Riser as a beacon of fire blasted towards him. The beam hit and consumed Riser and half of the arena. The magic released would crush any person who didn't, themselves, possess strong magic power.

"Hmm, should've used an eighth of my first container."

The flames cleared and revealed the charred and smoking body of Riser Phenex, truly a roasted chicken now.

"Game End! Lord Natsu Dragneel wins!"

"Yeah! I can marry Rias now!"

"Rias congratulation on your marriage!"

"I think he'll be a fine husband!"

"Even though your engaged, make sure to leave me some too~!"

Rias was bombarded with congratulations from her peerage. Each exacerbating the blush she had. This meant that she and Natsu were engaged and that meant marriage and that meant the honeymoon. had stopped working. Akeno was glad to see everyone having fun, but she wanted to address another matter.

"So, does anyone know what Natsu meant when he said, Quarter First Origin?"

"I released a few seals to give me 25% of my first container of magic."

Natsu explained, as he walked towards them.

"Wait! So that means you weren't even at full power! And you smashed up half the stadium when you blew up Riser!"

The devils that were also spectating from the sidelines gasped in shock and amazement.

"Not exactly, you see I have four origins, containers if you will, and each are filled with my magical power to varying degrees with the largest amount stored in my fourth. Meaning the smallest amount was in my first. So… if anyone were to hurt Rias… you'll be beat so hard that you'll need constant healing magic for a year!""What about me~."

"Y-yeah Natsu! Won't you protect all of us?!"

"In protecting Rias I mean I would protect her and everyone special to her and you guys are also special to me."

"O-Oh! Smooth talk, huh?!"

"A-Ah I'm special to Natsu!"

Akeno and Asia were shot by another arrow from Cupid's bow. Natsu tilted his head looked at them curiously. During the exchange Sirzechs showed up to congratulate Natsu and his sister's engagement. Natsu gripped his hand in greeting.

"So you wanna go renovate Riser's engagement party?"

"Sure, if anything it will be of better use to us than to Riser's arranged wedding. Plus Rias, I'm sure Natsu would make a great husband! Especially when he proposed to you then fought for you and thought of you to fight for you."

"Onii-sama! I know that! But you don't have to say it out loud!"

Rias was known to hate it a lot when her brother teased her. But this was worse. Much worse. Sirzechs chuckled and began walking away with Natsu to the party vendor, there was still another event planned. Rias and her peerage rushed after them as they disappeared around the corner.

"Why'd you leave us?!"

"You know Rias, you look really beautiful in that dress."

Natsu turned around and grabbed Rias by the waist making use of her rush towards him. He stared into her aqua pools.

"T-t-that's not f-fair."

Rias tried to get back to the point and look away, but was drawn in by Natsu's gaze.

"So, that's that. We've got to get to our engagement party and to wait for our guest."

Natsu stepped back and turned to move again towards the party. He had effectively blocked Rias from her pleasure and reminded her of their relationship at the same time. Thus giving rise to an incredibly adorable and flustered Rias. Akeno noticed her silence and picked up the conversation in her place.

"Who's this guest?"

"Ah, you'll see. It's someone you know," Sirzechs answered.

They arrived at the engagement party where the devils had reassembled, after much maneuvering around after the chaos that had ensued from Riser's total defeat and Natsu's complete victory. Sirzehcs stood on the stage before them.

"As you know, Riser has been defeated, meaning that my sister Rias is now in the hands of the victor. I would also like to clear a misunderstanding; Natsu is not a part of my peerage."

Murmurs filled the hall again. Words not dissimilar to: "Then how'd he beat Riser!? Did he cheat or something?!".

"I assure you that the fight was legitimate. Natsu Dragneel is indeed a demon, however that does not make him a devil."

"Then where did he come from?"

"YEAH! How the hell do we know we can trust him!"

Dissension evident. Natsu examined the crowd before taking a stand next to the crimson satan.

"I don't expect you to trust me. I myself don't realise how I have appeared here. I appeared in the human realm, where I was met by Rias Gremory and her peerage. They didn't see any way how I could appear and neither did I! So, I understand if you wouldn't trust someone like me, diving into your world with no explanation and breaking up the ceremony between two high-class devil families. HOWEVER! I will not stand by if someone hurts the person that showed me kindness when I arrived!"

As Natsu had reiterated his point he thought to himself 'I actually came from the gap where I had survived for around 3000 years'.

"BUT WHY? Wasn't it obvious that Riser loved Rias!"

That must've been Riser's father speaking. He smelled just as arrogant and fried-chickeny, if that was a word(It was in Natsu's mind).

"DON'T GIVE ME THAT BULLSHIT! Riser and You only view her as a breeding cow to regrow the number of full devils!"

Lord Phenex gritted his teeth vexingly, this ruined his plans to assimilate into the Gremory family and take control of the underworld, but there wasn't much he could do when he didn't have any bargaining chip.

"Hey Old Man, if you want, I could fight you as well! Then we'll see who's right!"

Natsu challenged the irritated lord and indulged in the pleasure of watching his face contort in anger. He watched as Riser's father left the room. His wife and Ravel, looked apologetically towards Natsu and left with him. When she looked at Natsu, Ravel's cheeks pinked. She left in a hurry after her mother. 'Wonder what that was about?'

Sirzechs spoke, "Onto, the next matter, I sense that their is tension in the room so why don't we relax and enjoy a different engagement party in the same venue!"

At his command, the party restarted and the tension left the room. The guests began mingling again. Natsu picked up conversation with multiple devils that ranged from young to old. When he talked with the younger devils the main topic was typically fighting. He also met Sairaorg Bael, current ranked first place in rating games. Sairaorg had suggested they spar sometime in the future. Natsu accepted with a grin, "I'll take you on any time! Except maybe not right now."The older devils were polite, but Natsu saw through to their hidden agendas, to collect him into their households/peerages to boost their rank and power. He, obviously, declined every attempt.

Talking to the devils he noticed that Rias was standing around with no one to talk to.

"Would you like to dance?"

"Oh Natsu! Yes, I would love to, my fiancé."

Rias tested the words in her mouth as she accepted his hand. They walked onto the ballroom floor and began to waltz. Their steps gracefully flowing together like eddies in a stream. They flowed around the ballroom. Many had stopped to watch them dance, for never had they expected Natsu and Rias dance in such an angelic(A/n: Pardon the Irony) way. Natsu internally thanked Lucy for teaching him, but when his thoughts turned there, his eyes went dark.

"Natsu, is something wrong?"

Rias looked at Natsu's face to see his shadowed eyes.

"Ah, it's nothing, just some old memories."

Rias grew jealous again. If he were thinking about another girl while they were dancing together and were together together, then so help him. She pouted and looked up at him. She said, with a sultry tone, "What old memories?"

"I was just remembering my who taught me how to dance."

"*Gasp* So it was another girl!"

Rias glared at Natsu, who looked back in a half-confused manner. It struck him about two seconds later.

"Oh! I'm sorry Rias I didn't mean to think about another girl while I'm with you, but it's just that she was a good friend and dancing just reminded me of her and old times!"

"That's okay, I guess." Rias continued to pout, as if she wanted something.

"I guess I'll have to make it up to you. To make sure you're okay."

They stopped dancing as Natsu bought his lips to hers in an ever so familiar situation. However when they touched lips, the doors slammed open with a voice screaming "I OBJECT!"

When the intruder looked around the room, he saw the precarious situation that Natsu and Rias were in and rushed over, pulling his fist back to punch Natsu. Natsu caught his fist and grinned.

"Hi Issei."

"Oh, Hi Nats- WAIT! HOLD THE FUCK UP! WHY ARE YOU KISSING RIAS?!"

"We're engaged."

"WHY~?"

"He saved me from Riser's clutches."

"Augh! I WAS TOO LATE~! NOW HOW AM I SUPPOSED TO BE HAREM KING WITHOUT MY BEAUTIFUL QUEEN RIAS!"

"That's my fiancé you're talking about."

Issei shut up his rampage when he heard Natsu's deadly voice. Natsu tended to be overprotective of what was his, a trait cultivated by his years in the gap. Issei practically pissed his pants after hearing Natsu's voice, it wasn't helped when his gauntleted hand was almost crushed in Natsu's grip.

"I see our unexpected guess has arrived."

Sirzechs appeared to explain the situation.

"You see, Natsu and I, had plans for you to arrive slightly after the actual engagement so that Natsu can save Ria and become her fiancé. This meant that we could have you demonstrate you power."

'Without risk of Ria still being married to Riser, I don't fully know Issei's abilities, but I would rather trust Natsu with a contingency plan, than leave everything to Issei.' Sirzechs, the ever-scheming, thought quietly to himself. This sentiment was shared with Natsu, who obviously had assisted in the creation of this plan.

"Demonstrate my power?"

"To let the devils know of your existence. We want you to fight with someone that can prove your abilities."

"Sure, I'll fight!" In Issei's head: 'If I show my power I can gain the love of the female devil population and become harem king!'

"Good! You're opponent will be Natsu."

The sound of Issei's heart breaking could almost literally be heard. The tinkling shatters echo across the room, much to Sirzechs and Natsu's mirth. They saw the comical soul float from Issei's body. Natsu slung his arm over Issei's should and grinned.

"I'm not gonna fight back for an amount of time though!"

"Phew! If you went out of the gates with guns blazing, I wouldn't be able to show off any of my powers."

"Well of course! What's the point in me showing off twice in a row!"

"Twice? Oh, right because you defeated Riser and became Rias'- Rias'..."

Issei fell into despair again. His dreams of having the perfect harem again realised.

"Of course you can have whatever you want since it wouldn't be very fair if you had to fight without a reward,"stated Sirzechs with a smirk, enticing Issei with promises of whatever he wanted. This tactic always worked on any race, even angels, as all races have desires or wants. Issei's eyes twinkled.

"THAT MEANS! I JUST HAVE TO WRECK NATSU AND I CAN HAVE MY PERFECT HAREM!"

Issei's vulgar screaming brought the stares and glares of disdain and scorn from virtually all the devils present. So, with that note, Sirzechs set the second fight of the day underway.

"My fellow esteemed devils, I am about to give you another fight! This one will be between the fire demon E.N.D and someone many of you might know already, the wielder of the sacred gear of the Red Dragon Emperor, Issei Hyoudou! It will be demon versus dragon!"

Again, murmurs filled the room. Many of the devils had already known of the Red Dragon Emperor's appearance and had their interest piqued when they found out he had become a devil. Despite, just watching one fight, many devils wanted another, mainly younger devils, but some of the scheming older devils as well. Again, most made their way to the stadium.

"Hey pervert! Know that if nobody's cheering for you, I will."

"What are you talking about!? I have Rias and the club members!"

"I'm sorry Issei, but we won't be cheering for you."

"NOOOOOO~!"

Issei's hopes and dreams of seeing busty and beautifuls jumping and cheering for him were ruined by Akeno's sadism. The group abandoned him to Grayfia who had also appeared when he showed up. However before they left Natsu talked to Grayfia causing her to blush, before leaving to his side of the arena prep rooms. 'Wonder what that was about?' Rias shook that thought from her head before leaving with her peerage to the arena stands once again.

Grayfia's voice echoed across the stadium.

"This will be the fight where Master Dragneel will fight the Red Dragon Emperor, Issei Hyoudou."

"I'll only have ten seconds to last is that okay?"

"It's fine, I can sense you're a lot stronger than Riser was right now. Remember I'm just gonna be standing here so give it all you got!"

"Begin!"

Issei pulled out his balance breaker, shocking most of the present devils. Natsu smirked, in such a form he might actually be able to do some serious damage. Issei knew, from their 'sparring', that nothing but the most powerful would work on Natsu, so he began charging his boost. Boost! Boost! Boost! They repeated hundreds of times within the span of those ten seconds. Issei released the shot on the tenth second as his balance breaker faded away. The green energy beam flew towards Natsu. Natsu, true to his word, stood there and took it even knowing that there would be some effect. He groaned in agony; clenching his teeth. It wasn't the pain that was doing this, it was something else. It was the draconic from Issei's blast! He remembered that Issei practically had a dragon living inside of his arm, and now that he had traded away the arm to become more powerful, it was akin to bathing Natsu in dragon's blood! He could feel the seal around him weaken. His last conscious thought was how much shit he would've had to explain later. Natsu exploded, his seal cracking enough to cause a consistent leak of his draconic power, shocking those in the stands further. The stadium melted as Natsu fell to his knees, his hands dropped and began sinking into the floor. He was physically unharmed, but on the inside the dragon was trying to get out again. Trying to change back to its rightful form. 'What are you really Natsu?' Rias' last thought as the stadium exploded to Natsu's power, forcing both Issei and him to be teleported out.

The last part was rushed and terrible writing on my account, I'll get back up to proper style next week, it's a public holiday for a week so I'll have loads of time to write and correct stuff. Again, I'll be posting in around two weeks time, till then bye! Strategic-class Slayer will be posted next week, I've been neglecting it. D:

Happy Valentine's day everyone!

P.S For my fellow loners, I give you fictional obligatory chocolate.
