Chapter 13

(The Underworld )

It was two days after the Rating Game for Rias's engagement and all participants had been fully healed, which meant that the engagement party was to take place tonight, in the grand hall of the Lucifer Castle. It was as these proceedings were taking place that Issei appeared in the Underworld, having used the magic circle that Sirzechs had given to him through Grayfia. He had just been approached by the maid barely half an hour ago and not so subtly encouraged to go to the engagement party to challenge Riser again for Rias's engagement. Apparently Sirzechs's believed enough in the strength of the Boosted Gear and Issei's devotion to his King, Rias, that he was gambling her future on him.

Striding through the entrance of the castle and heading for the large set of intricately carved wooden doors, which bore the crest of House Lucifer for all to see. Issei was muttering to himself, trying to boost his confidence as he prepared for what he was about to do, unfortunately though his charge for the doors was interrupted by the sound of a familiar voice.

"Hello their Issei-kun, nice night we are having isn't it?" Came the smooth voice of the 'Behemoth' Naruto Uzumaki, as he appeared from the shadows at the side of the doorway a welcoming smile on his face, dressed in a black tail coat, with a crisp white shirt and black silk tie and finished off by a burnt orange waist coat and black trousers with polished black dress shoes.

"What the hell do you want!?" Issei angrily retorted as he remembered how Naruto had interfered before, making it so Rias and her peerage had no extra time to prepare for the Rating Game against Riser.

"Why I am just out here to see what you are doing?" Naruto responded his smile still in place as he took step forward so he was just about blocking Issei's way into the grand hall of Lucifer Castle.

"What do you think I am doing here?! I am here to save Buchou!" Issei shouted as he glared at the silver haired devil for blocking his way.

"And what gives you the right to interfere in an engagement that had been agreed upon before either you or Rias-chan were born and was fully signed eight years ago?" Naruto asked cocking an eyebrow in curiosity as he awaited Issei's response. He personally found the idea of arranged marriages repulsive and had always been quite vocal in his opinion, despite all his years alive and the cynicism that comes with that he still believed you should only marry for love, and that you should only sleep with a girl if you have a connection. Which was lucky as Naruto was very good at making connections, even if they weren't permanent ones.

"What gives me the right?" Issei asked quietly as if he couldn't believe the temerity of Naruto for even asking such a question, "I have every right, after all, RIAS'S VIRGINIRY IS MINE!" he finished with a loud shout.

"…" Naruto didn't know what to say at that as he just looked blankly at Issei his mouth slightly a gape.

"Rias-buchou's virginity is mine and her boobs are mine!" Issei continued ignoring Naruto's silence as he nodded to himself at his bold proclamation.

"In my years alive I have seen the horrors beyond reckoning, I have witnessed atrocities that made even me weep, I have seen empires rise only to be ground into dust by the steady march of time. I have seen man evolve from savages with bronze weapons and clubs into what they are today, but never in my life, have I ever heard something as stupid, retarded and just plain ridiculous as what you have just said!" Naruto finished, genuinely surprised at Issei's reasoning, he was expecting some crap about bonds, friendship and love. The kind of stuff he used to say when he was much younger and much more naive about life and people. But what Issei said, not even Jiraiya, Naruto's godfather who had been the height of perversion had been this bad, he was a pervert yes, but he still had something more about him than that, he wasn't as one dimensional as Issei.

"I don't care what you say! I am going in their whether you like it or not, and when I do get in there I am going to beat Riser-teme and his whole peerage if I have to. I will fight the entire underworld if I have to, but I am breaking Buchou's engagement! Now get out of my way!" Issei said, so single minded in his perverse determination, that he hadn't even bothered to properly listen to Naruto.

"Sure man, if that is what you want to do go for it!" Naruto said as he forced a brilliant smile on his face before standing aside, giving Issei an encouraging slap on the back as he did so.

Staggering slight from the backslap Issei forged on ahead, moving to the large wooded double doors without even a backward glance. Which was a pity because if he had he would of seen the victorious smile on Naruto's face, and maybe even the faint glow of a blue seal made from numerous tiny kanji disappearing as it took full effect on its recipient, Issei.

"What a fucking idiot!" Naruto said to himself as he saw Issei throw the doors to the grand hall open, before he stormed inside, Naruto getting a slight glimpse into the room of all the shocked faces of the guests, as Issei made his dramatic entrance.

"I am surprised you let him go Naruto-sama?" Came a soft emotionless voice from Naruto's side as Grayfia appeared using the House Lucifer magical circle to arrive.

"Really Gray-chan, you thought I would actively try to stop him?" Naruto asked bemused as he turned to face the beautiful grey haired woman as she stood before him, still wearing her normal maids outfit.

"Considering you seemed to have actively tried to make sure this engagement went ahead, despite your own feelings on the matter, then yes I did think you would stop him." Grayfia replied as she sent Naruto a slightly suspicious look.

"Is that why you are here then, to stop me in case I did get in Issei's way?" Naruto asked his golden eyes twinkling as he looked at Grayfia, "Do you really think you could have stopped me if I tried?"

"No, but I know I would have delayed you enough for Issei to get past you anyway, even if it meant getting badly injured in the process." She replied simply looking Naruto in the eyes as she did so.

"Badly injured?" Naruto said his eyebrow rose before asking, "And what make you think I would only injure you, and not kill you for attacking me and getting in my way."

"Because you still love me." Grayfia replied, without a single hint of doubt in her voice.

"Yes, yes I do. Just as much as you love me." Naruto replied, taking a step closer to Grayfia as he did so.

"I am married to Sirzechs's!" Grayfia said, her voice hardening slightly at Naruto's statement, but despite that she didn't step away from him.

"Yes you are married to him, but you don't love him."

"Yes I do."

"No you don't, you like him yes but you don't love him. I can see it in your eyes when you look at him and in the way you act when you are around him. Your marriage to him lacks any passion to it doesn't it." Naruto said taking another step closer to Grayfia, his eyes locked onto her own sparkling grey ones.

"I am happily married to Sirzechs's!" Grayfia stubbornly replied frowning at Naruto as she did so, but still not stepping back. Even as she felt the heat radiating from Naruto's body, and the scent of his body, an earthy smell, like a blooming forest after a sudden shower of rain.

"You're married to him yes. But not happily, you are a woman of passion; you always were so full of joy and loved life to the fullest when you were with me. Now, now you act as a maid to a spoilt child like Sirzechs, trying to bury your unhappiness behind a façade." Naruto continued undeterred by Grayfia's stubborn denial. "Why did you ever marry him, Gray-chan?"

"Because you left, you went off gallivanting around the world, finding and reincarnating your old friends into Devils for your new peerage. Because you allowed Serafall to make you her queen without thinking of how I would feel about it. Because you left me, at a time when I needed you most, my friends and family were either dead or branded traitors, many of the noble families looked at me with distrust and hate, you left me alone at eh worst time in my life." Grayfia half shouted her emotionless façade breaking as she looked at Naruto with a complicated mixture of sadness, betrayal, love and longing.

"I, I'm sorry Gray-chan." Naruto said his voice breaking slightly as he realised what a massive idiot he had been, all this time he thought she had left him, but it turned out it was the other way around. "I know there is no excuse for what I did, it's just I was so excited when Ajuka-kun announced his creation of the evil pieces. I just got carried away as I realised it meant I could bring back and revive my precious people, the few people who in all my thousands of years alive I made true bonds with, people who I thought I would never see again, brought back to life, their bodies removed from stasis and given new life. But in my excitement I never realised what my leaving did to you. I am so sorry Gray-chan."

"I know you are, I know you didn't realise, but it still hurt. This is why when you left me at the time I needed you most I almost broke. It was only Sirzechs's hounding, and his constant date requests and courting attempts that stopped me from losing it. He offered a form of support, even if it was in his own odd and obsessive way and I will be forever grateful to him for that." Grayfia replied to Naruto, her heart hurting as she saw the sadness in Naruto's eyes.

"Do you think there could ever be another chance for us?" Naruto asked his eyes glinting with hope as he met Grayfia's confused grey ones.

"I, I don't know." Grayfia replied as her heart told her to say yes, to take her one true love into her arms and never let go, to introduce him to her son and find true happiness for the first time in centuries but her head was far more cautious and level headed. "We could try and be friends first and see how it goes?"

"I would like that." Naruto replied as he unconsciously leaned closer to Grayfia.

"Then we are agreed." Grayfia responded even as she leaned forward, her heels leaving the floor as she did so. Before without any other thought their lips crashed together, Naruto's arms encircling Grayfia as he pulled her to him, her body melding perfectly with his. Her own arms running up his back before the lodged themselves in his silky silver hair, using her hand hold to pull his face closer to her. As they continued to passionately kiss Grayfia started pushing forward, backing Naruto into the wall besides the entrance to the grand hall. Her soft tongue slipping between her lips and meeting Naruto's halfway as they began a sensual dance their mouths.

As Grayfia was doing this Naruto's hands had glided gently down Grayfia's back feeling her frim and sculpted body before ending up on her round and supple ass. His hands gently cupping them before he began to knead her dress covered cheeks.

Before they could go any further though they were interrupted by an obnoxious shout from within the grand hall.

"RIAS-BUCHOU'S VIRGINIRY IS MINE!"

Upon hearing that crude statement Grayfia sprang away from Naruto as her mind finally caught up with her rapidly beating heart. "I, I'm sorry I have to go, I have duties to do. Yes duties. But we will talk about… this again later." She said her face flushing red as she tried to look anywhere but at Naruto, before she quickly summoned a magical circle and teleported away.

"Fucking Issei!" Naruto cursed as his own heart raced, he had only felt this way about a woman three times before and that was with the three women that he knew without a shadow of a doubt that he loved more than anything else, more than his dream, more than even his own immortal life. "Yep, I am definitely going to break that kid for this."

(Within the Grand Hall)

Entering through the pair of large double doors, an annoyed Naruto found himself standing in a room that was every bit as ostentatious and over the top as one would expect from an important devil family. The room was massive, the cavernous room made for huge parties and gathering of hundreds. The floor was polished black marble, the walls being made of an expensive wooden panel and decorated with dozens of expensive paintings; they also contained large ornately crafted windows whose sliver frames were engraved with the symbol of House Lucifer.

Filling the ostentatious hall were hundreds of Devils, all dressed in suits both modern and old fashioned, some with long-tailed tuxedos and clearly ridiculously expensive dresses. One thing that all the Devils in the room had in common however was the look of shock on their faces as they stared at the scene before the. Issei dressed in his Kuoh school uniform stood at the front of the room loudly confronting Riser Phenex, who stood in a fancy white suit with an open white shirt, next to Rias Gremory who herself was wearing a wedding dress.

"Yakitori-teme!" Issei shouted pointing his finger aggressively at Riser. "I've come to take Rias home; she's not marrying a scumbag like you!"

At those words the surrounding crowd began to whisper to each other as they watched the going scene happening, many looking confused and upset about his interfering in such an important event. Many were even making snide comments about reincarnated devils and how they should not be invited to event for proper devils.

"People be at peace, this is only an event that I arranged." Sirzechs said calmly as he emerged from the crowd clad in his armour and cloak, a gentle smile on his face as he spoke.

"Brother." Rias said as she looked towards her older brother a flicker of hope in her blue green eyes as she did so.

"Lucifer-sama!? Surely you can't possibly have done something so irresponsible!" One of the devil elders spoke up, the middle-aged looking devil clad in something that would not be out of place in the 16th century.

"Oh I could, and I did. The reason being simple, I wanted to see the power of the wielder of Boosted Gear Longinus against the Phoenix, so I arranged it myself, as entertainment for the engagement part." He revealed smiling enigmatically to the surrounding devil nobles, before his eyes met Naruto, at which point they turned smug. "The Rating Game was of course entertaining and all, but my sister was at a great disadvantage since she had no experience, compared to your numerous multiple victories in your Rating Games, Riser. But despite this and despite your considerably larger forces she nearly beat you"

"So you're saying that it was unfair Lucifer-sama? After all it is the final result that counts my lord!" Riser said to Sirzechs as he took a step forward a glare on his handsome face.

"Not at all Riser, after all as a Maou I can't be biased to anyone family and certainly not my family. But this is a very important matter for Devil society after all. And I hardly think your family is proud, especially after how hard a first timer like Rias-chan pushed your peerage. Besides you didn't even fight yourself, so I think you should be given another chance."

"What are you suggesting, Sirzechs-san?" Naruto asked as he came forward from where he was stood next to Serafall, who was now dressed in a silky green dress that hugged her body, a smile forcing its way onto his face as he gained the attention of the entire hall. Keeping his tone civil as they were surrounded by many important families and it would be inappropriate for the two to show their usual animosity.

"Why it is quite simple Naruto-san. I wish for my cute little sister's engagement party to be flashy, and you never actually got to fight in the Rating Game with Rias-chan. Dragon vs Phoenix, surely the rest of the party would agree with me on the matter, I believe it would be quite the sight to see a match between two powers such as yours. Truly a once in a lifetime opportunity, if you ask me." Sirzechs said charismatically a wider smile on his face, before he turned back to Riser. "What do you say Riser-kun, will you show off your powers for us all?"

Riser as he heard that gained a confident smile as he heard Sirzechs flattery, oblivious to his true agenda his arrogance blinding him to the truth. "How could I decline a request from a Satan, from Sirzechs Lucifer-sama himself for that matter? Very well, Riser will show his powers to everyone before he is to wed and bed his dear Rias-chan."

As Riser finished his monologue many of the watching devil nobles cheered for the entertainment to come. Some though didn't look so happy with his decision, his parents Lord and Lady Phenex for one and his peerage for another. His sister Ravel and his rook Xuelan looking the unhappiest of the lot, as Riser in his arrogance threatened to undo all of the hard work they did on his behalf.

"So tell me Dragon if you are the victor, what would you like to have as your reward?" Sirzechs asked as he turned to Issei who still stood defiantly before Riser.

"You can't be serious Lucifer-sama, a reward for lower-class devil scum like him!" Riser sneered out as he glared at Issei, remembering him from his initial meeting in Kuoh.

"I have spoken, lower-class or not he will get his prize. I am the one who is requesting this of him, so I must give him compensation for his trouble." Sirzechs declared as he looked around the room magnanimously as if looking for anyone who would disagree with him, which no one did, surprisingly enough not even Naruto. "What would you like to receive? Ask and if within reason you will be granted it."

"Fine there is only one thing I want, Rias Gremory." Issei shouted out, making the crowd mutter between themselves, with Rias and her peerage throwing Issei grateful looks.

"Well then," Sirzechs said looking between Issei and Riser as he did so, before he sent Naruto a smug smile, "Shall let us begin?"

(Rating Game Arena - 10 minutes later)

"The challenge for the hand of Rias Gremory fought between Riser Phenex and the Issei Hyoudou shall now begin!" Came the now calm and collected voice of Grayfia as she once again was the announcer for the game.

The two combatants were stood in a large stone arena almost coliseum like in its design. The arena was surrounded by a ring of steps, and by several massive stone chess pieces that seemed to boarder the whole arena. The sky was a cloudy red, with twinkling stars being visible in the sky as Issei and Riser Phenex faced off against each other.

"I am ready if you are Riser!" Issei declared confidently as he raised his fist, preparing to call on his Sacred Gear.

"I will take you down a few pegs, come boy fight me!" Riser shouted as two wings made of fire erupted from his back, lifting him into the air ad he looked down on Issei.

"Alright let's go, Boosted Gear!" Issei shouted as he ran forward, attempting to summon his Sacred Gear as he did so. Only for him to fail, as unnoticeably the seal Naruto previously placed on his back temporarily block him from accessing his Sacred Gear. It was a very complicated seal, which affected a person's control over their Sacred Gear, for a newbie like Issei it was very effective. Against someone more powerful and experienced though, it would be less so.

"What the fuck!" Issei shouted as his Sacred Gear to the surprise of all but a certain few failed to appear.

"Ha! How pathetic, not even able to use you own Sacred Gear, and you thought you stood a chance against me!" Riser laughed down at Issei.

"I'll show you, Promotion Queen." Issei shouted as he continued to run towards Riser, trying to use his augmented power as a temporary queen to use his Boosted Gear.

"It's no use!" Riser shouted as he dived from his place in the air, down towards the charging Issei.

"Die!" Issei desperately shouted as he went to punch Riser, hoping for a miracle.

Only to receive a flaming punch to the face, this smashed him into the ground forming a crater beneath him. This was followed by Riser unleashing his full fury on him as he sent waves of fire at his fallen body.

"Issei Hyoudou has been retired from the game, Riser Phenex is the winner!" Came Grayfia's voice, holding a hint of surprise at the brutal and very one sided beat down.

( - )

(In the Grand Hall)

"Well! That was fast wasn't it?" Naruto spoke into the silence that had followed the very quick match, this was promptly followed by a few laughs and a lot more muttering as everyone started talking about the surprising result. "So much for being entertaining, eh Sirzechs!"

"W-What? But, what happened, why couldn't he use his Sacred Gear?" Rias shouted out as she stared in horror at what had happened to Issei and her last chance of getting out of the engagement.

"Rias-chan!" Akeno shouted out as she and the rest of Rias's peerage ran to Rias's surprise for support.

As this was happening, Riser once again appeared in the grand hall in a pillar of fire. "Well that was quick wasn't it?! So shall we get on with the marriage then?"

"No!" Rias cried out desperately as she looked to her older brother Sirzechs for help, the crimson haired man no longer smiling as a look of dread crept across his face.

Turning to his sister, Sirzechs saw the fear and terror at what was to come in her eyes and quickly made a decision. "I am afraid not Riser, in fact there shall be no wedding at all!"

Silence.

Then;

"What!"

"What are you talking about Lucifer-sama, no wedding?"

"You have no right!"

"What is this!?"

Raising his hand for silence Sirzechs once again looked at his now crying sister, before he turned his gaze to a smug looking Naruto, who he then glared at with hatred, he spoke again. "I am using my power as Maou to nullify the contract."

"That is forbidden, you are showing favouritism for your former House. The law of the new Satan Faction strictly forbids this." One of the elder council in attendance shouted out, many other Devils in the crowd nodding in agreement.

"You are of course right, which is why it will be my last act as Maou Lucifer as I abdicate my throne." Sirzechs said solemnly, his statement causing the crowd to quiet. "Furthermore, I make a request of the remaining Maou here to nominate Grayfia Lucifuge as my successor; she is an Ultimate Class, pureblood Devil with the full support of the House of Gremory behind her."

At his request many of the devils in attendance started shouting out in agreement, a few of the younger ones chanting her name.

Rias and her peerage as well as Riser and his however, stood in stunned silence as historic and life changing events rapidly took place in front of them, unsure what they should do. Though Rias could only look at her brother with awe for his sacrifice for her and shock at what he had just done what he had just given up.

"The Maou do have the right to nominate a new Maou." One of the elders in the crowed agreed as all eyes turned to the calmly standing figures of Ajuka Beelzebub and Serafall Leviathan.

"And you are right in that, so now we shall choose a preliminary nominee, until such a time as the three remaining Maou can meet and agree on a new Maou Lucifer." Serafall called out in a very serious voice, getting the attention of everyone in the room as she did so; turning to glance in Naruto's direction she received a smile and a nod. "Therefore by my right as Maou Leviathan, I Serafall Leviathan do nominate my queen Naruto Uzumaki or 'the Behemoth' to be the new Maou Lucifer. He is easily one of if not the most powerful devil, pureblood or reincarnated, in existence. And he has the full support of House Leviathan and House Sitri!"

As soon as Serafall finished her nomination Ajuka also loudly spoke up. "And I by my right as Maou Beelzebub do nominate Naruto Uzumaki or 'the Behemoth' to be the new Maou Lucifer. He has the full backing of the House of Beelzebub."

With that said the room exploded into noise as some cheered and other booed. Sirzechs through Ajuka and Serafall a look of betrayal, and many of the members of the Elder Council present gained scowls."

"He can't!" Sirzechs shouted his power flaring as he lost a bit of control. "Reincarnated devils are forbidden from becoming Maou!"

At his words many of the Elder council and some of the purebloods, shouted their agreement. Whilst the reincarnated devils and more liberal purebloods in the room, started shouting at Sirzechs and booing his statement. With things starting to look ugly in the room, many devils started drawing on their power, as if expecting a fight to suddenly breakout.

Before it did however Naruto finally spoke, with a single flare of his titanic power he cowed almost everyone in the room into silence, causing multiple cracks in the floor and walls as he did so. "I am afraid you are wrong their Sirzechs," Naruto said into the silence.

"How!" Sirzechs snarled back with a ferocious glare.

"A reincarnated devil is forbidden from challenging a Maou; yes you got that law passed pretty quickly Sirzechs. But there is no law anywhere saying that a reincarnated devil couldn't be nominated by another Maou for the position. And I just received two nominations!" Naruto said cheerfully his face victorious, as his long and carefully laid plan came to fruition. "Besides, Naruto Lucifer kind of has a ring to it. Doesn't it?"

AN: Thought this would be a good place to stop with a shocking reveal. I was a bit tired when I wrote this, so I may come back later to clean it up a bit.

Will probably extend bits and add a bit more description and dialogue, maybe.

Hope you all enjoyed it, I am knackered and going to bed.
