True Dragon

"Issei, come in." Sirzechs ordered has Issei stepped through the two grand oak doors to the throne room. "You asked to see me lord Lucifer?" Issei bowed to Sirzechs as this was a meeting about business. "Yes, I hear you've completed your training with your grandfather is that correct?" Issei's grandfather was none other than the dragon king Tannin. His mother was Tannin's eldest daughter and part of the Lucifer peerage. "Yes sir, but I fail to see why you have called me here." Issei asked with confusion in his voice. He wondered why Sirzechs with an already complete peerage was asking to see him and on top of that was asking about his training.

"You remember my little sister Rias? Well she has been gathering her peerage but has yet to find a truly powerful member, her queen, rook, and knight have the potential to be powerful but they aren't ready for a serious fight." Sirzechs made it clear to Issei that he was going to be asked to join Rias's peerage, he thought it over and worked out he could do a lot worse than Rias as a master. "Sir, I take it I'll be joining Rias's peerage as a pawn, seeing as though she doesn't have the remaining pieces to take me on in any other role." Issei asked the obvious question, with his power he was worth at least 8 pawn pieces or two of the other pieces, his power rivalling his grandfather's and being trained allowed him to use that power to its limit.

"Well sort of…" Sirzechs began "sort of?" Issei asked again confused. "Beelzebub has been working on a new piece to replace 8 pawns with one insanely powerful piece, it's called the vanguard piece and it basically gives you the ability to take on every last position in the peerage at will." Issei was impressed by the sound of this but first things first, Rias needed to accept him into her peerage. "My sister is on the lookout for talent and raw power, and it just so happens that there's a stray devil in her territory that we've yet to tell her about. Basically Issei I am going to inform my sister of this stray devil and you are going to kill it just as she and her peerage arrives." Sirzechs had thought of a plan to get Issei recognised by Rias, Issei just sat listening to the plan and agreeing to what Sirzechs had suggested. "Rias has always been inquisitive, if she notices something unusual then she will investigate it, so you're also going to be attending school in the human world with her, but I want you to let her approach you once she sees you leaving the stray devils hideout after killing it seeing you at school will definitely spark her interest." Sirzechs knew his sister down to the last detail the plan was flawless, except for one thing. Where would Issei stay during his time at school?

After the meeting with Sirzechs Issei returned to his family home in the Lucifer capital, a very large European style mansion with 3 floors and a huge garden surrounding the house. "Mom, Dad I'm home and you'll never guess what task I've been given." Just as Issei shouted this his mother in her human form poked her head out of the living room, "ooh, let me guess, you've been asked to join the devil military as an officer?" Issei's mother asked with stars in her eyes. "Nope" Issei replied "even better, I'm going to be the first vanguard piece and I'm going to be part of Rias's peerage." Issei proudly proclaimed. "Well then" Issei's father began "if that's the case you'll need some money to go to the human world, now let's see…" he trailed off as he opened up a magic circle to check on how much money they had set aside.

That night after Issei's father had given him a substantial amount of money to survive in the human world ($3.5 million) Issei arrived in Kuoh near where the rouge devil was meant to be hiding out. "Hmmm, 10:05 PM Rias and her peerage should arrive any minute now", Issei mused to himself as he casually strolled into the stray's lair. "Such power, I've never had the pleasure of devouring someone as strong as you." The distorted voice of what used to be a woman echoed through the building, Issei used his dragon senses to pick up on where the rouge was hiding. "You know you really should pick a better hiding spot then behind the pillar in the east end of the room." Issei teased hoping to get a response from the stray. "Cocky little shit!" the stray roared as it smashed the pillar and made a break straight for Issei.

Outside Rias and her peerage had just arrived and were discussing the plan on how to take this rouge devil down. "Ok Kiba I want you to attack first and cut off its arms, without those it'll be limited to attacks, Koneko, I'll be counting on you to put it on the ground, drop it hard and fast, Akeno…" Rias hadn't finished giving her orders when the stray's voice rang out from inside the building "Cocky little shit!" The Gremory group looked at each other before rushing to find out what had caught the stay's attention and more importantly what had pissed it off so much.

Back inside Issei dodged the initial attack as Rias and her group slid in through the door and hid behind some crates. The stray slashed at Issei with its claws only to miss as if trying to attack a ghost, "I've had enough of you! Die!" the stay let out a massive demonic blast towards Issei, Rias who was watching in terror decided to shout out to the man fighting this creature. "For fuck sake, move!" Issei turned his head towards her and smiled, as the blast hit him the ground shook, dust and smoke erupted into the air. Issei just stood there with his arm stretched out. "Wow, that actually stung a little, good job, your most powerful attack and you fucked it up." Issei had finally had enough with playing and decided to end it quickly. "Since I'm in a good mood tonight I'm going to give you a choice, slow and painful or quick and painless, and since I can't be fucked to go for the slow and painful option I'd rather you don't pick it." Rias and her peerage were shocked and silent as this 16 year old boy was stood in front of a very powerful stay devil and wasn't just winning the fight he was actually asking for more by tormenting it.

"Get fucked brat!" the stray screamed at Issei before charging. "As you wish" with that Issei's extended hand started to glow bright red until a wave of demonic and dragon power shot out and instantly vaporized the attacking stray. "Well that takes care of that, see you guys tomorrow." Issei shot a glance towards Rias in particular before spreading his dragon wings and disappearing through the roof. Rias looked around before asking what everyone was thinking, "Ok, who and what the fuck was that?" "Ara Ara, it seems things are going to get interesting around here." Akeno answered, Kiba and Koneko just stood silent trying to work out what had just happened.

On the other side of town Issei had just landed on the roof of his new home, it was the penthouse apartment in the most expensive building in Kuoh to live, inside were 8 bedrooms, 3 bathrooms, a large dining room, a huge living room and outside on the balcony was a large swimming pool and rooftop garden. "Well Rias, you know I exist let's see what happens tomorrow morning." With that Issei retired to his bedroom and fell asleep sprawled out on his king sized bed. Meanwhile back in the old school building Rias and Akeno were thinking through what Issei had said. "I'll see you tomorrow, surely he can't plan on attacking us." Rias asked with a hint of worry in her voice "relax, the sheer power coming from him, if he wanted to kill us we wouldn't have walked out of that warehouse alive." Akeno gave her view, this was going to be a long, and worry filled night.

Ok so that was the first chapter of a story that will follow the main plot line but with Issei being tannin's grandson and with that being an extremely powerful royal dragon. Issei will be perverted to an extent and he definitely will be a lot smarter. I still plan on having him not giving a shit when it comes to Riser, that I am looking forward to because in all fairness, who even likes the prick. This is my first DxD fic so please review and give me some constructive criticism. While I'm at it I'd also like to say that high school DxD is not my creation nor is its characters. These both belong to the creator Ichiei Ishibumi. I will release the first two chapters at the same time then it should be a chapter every week or so.
