True Dragon

"Riser." Issei growled, his draconic power flaring causing even Grayfia to shake. Riser stepped out of his magic circle approaching Rias with a defiant smile on his face, Rias looked at Issei with pleading eyes begging him not to cause trouble. Issei lowered his guard slightly to relax Rias although he was still pissed and the whole room knew it.

"What are you doing here Riser? I have already told you I have no intention of marrying you" Rias hissed. Rias kept her eyes on Issei who was trying to quell his anger, she didn't mention that Issei's eyes had turned from his normal human eyes to that of his dragon form. Riser hadn't noticed this and continued to piss Issei off more and more.

"Rias my darling don't you want me?" Riser asked teasingly, Issei had managed to control his anger up until now but Riser was seriously pushing it. Rias sat down on the sofa opposite the rest of her peerage and Riser took his seat next to her. Issei summoned the boosted gear behind his back so no one would notice waiting for Riser to try anything.

"Riser for the last time, fuck off I would rather end my life than have to spend it with you." Rias was getting more and more agitated but nowhere near as much as Issei. Rias stood up to return to her desk, as she did Riser stood up and pinned her in front of him.

"Bad move!" Issei shouted as he unleashed a devastating shot from his left hand that had been doubled by the boosted gear. Riser disappeared through multiple walls and out of the wall on the other end of the old school building. Grayfia rushed to get between the Dragon and the phoenix but she wasn't quick enough Issei had spread his wings and launched himself outside following the hole Riser had left. Just as riser had recovered from the hit he found himself being pinned by a force not even he could shift. He opened his eyes to see Issei holding him down with one hand and his second hand charged with a power that would kill him without a doubt.

"Issei as the queen of the Lucifer if you continue this I shall have no choice but to kill you myself." Grayfia commanded in an attempt to pull rank on Issei.

"You would try, but my fight is with this bird brain." Issei responded to Grayfia's threats in a more calmed manner than he had used against the stricken Riser. Riser got up and clicked his fingers as 15 figures appeared out of a huge flame.

"If you wish to fight then how about we settle this with a rating game? You and your group verses me and mine." Riser smiled defiant even after being put on his ass by Issei no less than 2 minutes ago. Just as he said that Rias appeared in the hole of the second floor of the old school building.

"I accept your challenge, and Riser, you should thank Grayfia since she just saved your life. Had she not been here I would have lacked the mercy required to keep Issei from killing you." Rias spoke in a flat emotionless tone similar to Koneko. Riser standing back up wiping the blood from his face approaches his group, completely defeated in this battle.

"I look forward to burning your servant to a crisp Rias." Riser shot at the Gremory group as he and his group left through a magic circle. Rias turned to Grayfia and hung her head in apology.

"I'm sorry for how Issei behaved but his anger is my frustration given form. I don't care what brother and father think I am not marrying that obnoxious bastard." Rias spoke clearly to Grayfia laying down her terms with the Queen of Lucifer.

That night Rias stayed at Issei's place again, she and Issei were lying on the bed watching a movie as Rias's phone rang.

"Yes? I see… yes, 5 days will be fine… ok I look forward to it." Rias put the phone down and gained a face full of hatred Issei came up behind her and wrapped his arms around his master.

"I take it we have 5 days to train against Riser and the flaming fuck heads." Hearing this Rias giggled and nodded.

"Yes, and it seems the only capable member of my team is you, but we need to strengthen ourselves to beat him." Rias had now gained a smile and leant back into Issei, somehow she felt like nothing mattered when she was like this, it seemed that Riser, the three great powers, all of her worries just simply vanished.

"We can sort this out tomorrow, come on, let's get some sleep." Issei spoke in his usual calming tone and the two shared a kiss before falling asleep.

"Ok everyone welcome to my families lodge, we will be training here for the next few days for the rating game against Riser's peerage." Rias said energetically as the group set their gear down in the living room of the huge 20 bedroom mansion. Issei had brought some targets as he knew how he was going to fight the battle against Riser and his peerage. He and Rias had spoken about it and had decided that Issei would be the attacking entity in his dragon form with Kiba riding on his back knocking out anyone Issei misses. The plan was to have Issei fly directly for Riser and his base taking out any of the opposition along the way and then Issei would have fun with the defenceless Riser.

BOOM! The target instantly vaporized from a powerful shot from Issei who was doing his part of the training, he was flying through the valley destroying targets that had been randomly placed by Rias's familiar. Issei was flying at over 500mph ducking and weaving around the high valley walls. The rest of the Gremory group watched Issei's progress from the mansion, completely silent at how effective Tannin's training was and how powerful Issei could be.

After Issei returned the group agreed that he was as ready as he could be for this fight. From then on the group practiced tactics, fighting, magic and worked on knowing the Phenex peerage from broadcasts of their rating games from the past.

On the final night Issei was on the roof of the mansion looking up at the sky. He quickly turned to see Rias in her night gown with glasses and a book.

"Oh, Issei, I didn't realise anyone was up here, mind if I join." Rias asked even though Issei would never say no to her. Issei nodded and motioned to the space next to him, Rias smiled and sat down next to him and cuddled into her dragon.

"Issei, what would you do if we lost tomorrow?" Rias asked with a hint of worry in her voice.

"I'd crash the engagement party destroying everyone who stood in my way and then I'd kill Riser myself and take you back that way, there's no way I'm letting him take you away." Issei said with a straight face. Rias smiled and cuddled in even closer to Issei.

The two looked at each other and began to kiss, the kiss deepened and the two kept going further, Issei and Rias retired to Issei's room for the night, from that night on, Rias would be Issei's as the two became one.

The following day the entire group sat in the ORC club room waiting for the match to start, Issei had his armour on and his sword drawn even though Kiba was going to be the one using it. Issei looked at Rias and smiled knowing that no matter the outcome, no one could take last night away from either of them.

Just then there was a blinding light as the group was teleported to what looked like a city, tall sky scrapers surrounded the team who had teleported in on the roof of one of the smaller buildings.

"Greetings everyone, I Grayfia as maid of the house of Gremory welcome you all to the battle between Riser Phenex and Rias Gremory. This battle will take place in an urban environment with Rias's group's base being the top of the national banking building. Riser's group's base is 3 blocks over on the top floor of Griffon tower. We expect a clean game from both sides and may the best team win. Match start!"

Ok second chapter for today finished I hope this has gone to standard, yes I have a very special plan for Riser involving a very long fall (no spoilers), For those of you wondering, yes Issei and Rias did have sex, I'm just not at a stage where I think I can write a lemon yet, or even if I want to take this fic in that sort of direction. Anyway next chapter will be up in a few days so until then please review, as I've said before I don't own the dxd universe and make no money by doing this. Till next time.
