[Few differences. Asia never went to Kuoh for reasons to be revealed at a later time. Ravel is a lot younger. Like, she's 4 or five. Disclaimer: I can't speak Japanese. Fair Nuff, right?]
A brilliant red circle lights up the clubroom.
"Phenex," Koneko mutters flatly.
"Rias, my love! Riser is here!" A man and a woman appear. The woman has silver hair in a long french braid, and is dressed in a rather lewd french maid's uniform. The man is dressed in what are obviously rather well made and rather expensive clothes. Red pants, leather shoes, and a red dress shirt unbuttoned enough to show off his muscular chest. He had messy light brownish blonde hair, the exact same as Issei, actually. Rias looks over to gauge Issei's reaction, expecting him to be gaping at the silver haired maid. Instead, she was shocked to discover that he was staring rather intently at Riser. Rias shakes off the thought, turning back to Riser.
"Riser, I have told you many times, I will choose the one I marry!" Rias grinds out angrily.
"Rias, it's for the go-" Riser begins, before Issei cuts him off suddenly.
"Riser?" Issei says softly, yet loud enough for Riser to hear him with his Devil hearing. Riser turns to look at Issei, expecting to see one of Rias' silly servants, only to stop suddenly with an odd expression on his face. Riser doesn't say anything, and neither does Issei. They just stare at each other for a long moment. Riser walks stiffly over to where Issei was standing, stopping right in front of the wild haired pawn. Riser tilts his head to the side slightly, staring at Issei.
"Ise?" Riser asks softly. Issei nods sharply, trying to figure out how he knew the man in front of him. Issei groans suddenly, holding his head tightly, before he collapses. Before he could hit the ground, however, Riser catches him. The ORC stare at the two in shock. Riser puts a hand against Issei's forehead, before closing his eyes tightly in concentration. His hand suddenly burst into fire, but it seemed to not be hurting Issei. If anything, Issei seems to relax as the flames come into contact with his skin. They remain in this position for a while, until the flames completely envelope the duo. Soon after, the flames begin to burn white, before vanishing altogether. The ORC stares in shock as Issei straightens, and nearly tackles Riser in a hug, with Riser giving just as good as he got.
"I got you Ototo. I got you." Riser says to Issei, before holding him in front of him to inspect the Sekiryuutei. He seems to devour every detail of him.
"Aniki, what...what happened?" Issei mutters to Riser in confusion. Riser's face darkens immediately.
"You were stolen, Ototo. Stolen at the age of nine from your bed in the middle of the night. Mother and Father stopped searching after the first year, and you were declared dead by the Maou. But I never believed it. Never. I could feel it. I'm so sorry, I didn't protect you." Riser says mournfully, pulling Issei into another tight hug. Issei hugs him back for a moment, before they both let go. Issei returns to his seat ext to Rias, with Riser sitting Across from them next to Akeno.
"I guess I should start from the beginning. When I was thirteen years old, My younger brother, Issei was stolen from his bedroom in the middle of the night. We spent the next few years searching everywhere we could in the Underworld, and on Earth. Soon, the Maou declared him as dead. I never believed it. Soon, my parents had another child. Ravel. Our lmoto. I put everything I had into protecting her. I guess I felt that after failing to protect you, I would rather die than face failure again. So, I decided to become the strongest. I finished my peerage. I became one of the best in them, rarely tasting defeat. Things went downhill from their. Grandfather and all the Elder devils decided that the Heir of Phenex had to behave a certain way. So I did as I was told, hating all of it. I had to. They told me that if I behaved and did as they wanted, they would restart the search for Issei. When they told me that I was engaged to Rias, it broke my heart. I never wanted this Rias. this was not my decision. But, I went with it. Thankfully, I no longer have to carry on the charade. I can be me again."Riser finishes with a small smile. Rias stares at Riser in a new light.
Riser raises his head suddenly before looking at Issei.
"Issei, there are a couple of people who want to meet you, or see you again in some cases." Riser says. He snaps his fingers, and another Phenex seal appears. This time, fourteen appear. Before Riser can say anything, Issei stands. He approaches the group of new arrivals slowly before coming to a stop in front of two of them. The two girls, one with platinum blonde hair and the other with purple, stare at him for a few moments, before their eyes light up in recognition.
"Issei? Is that really you?" The purple haired girl asks softly, reaching a hand towards Issei. She touches his face lightly, as if afraid he was going to vanish at any second.
"Issei?" The blonde questions in disbelief before both girls smile widely and throw themselves at the brunette.
"Luna? Asia? Am I dreaming?" Issei asks. The girls squeeze him tighter in response.
"They decided to join my peerage until we found you. They believed as much as I did. When you receive your pieces, I'll trade you. They belong with you." Riser says with a smile. Issei looks to Riser with a look of shock on his face.
"My pieces?" Issei asks. Riser nods, and laughs.
"Of course! You are a high class devil, and fourth son of the Phenex family. Of course you are going to have a peerage." Riser says happily.
"If Issei is a pureblooded devil, then how was he a human before I reincarnated him?" Rias asks carefully. Riser thinks for a few minutes while Asia and Yebelluna continue to glomp Issei happily. Issei looks overjoyed as the large breasts of Yubelluna and the still developing ones of Asia were sandwiching his head between them.
"The best I can guess, the one who stole Issei also sealed his powers when he sealed his memories. Luckily, my flames were able to destroy that which was binding them." Riser concludes. Rias nods once.
"So, Omoto, you ready to leave?" Riser asks. Issei looks to Rias, who gives him a sad look, but nods anyway. Issei nods, and pulls away from his two childhood friends.
"Asia, Luna, you can go and collect your things from my home, as I am sure you will be moving in with Omoto. Issei, we have to go and visit our family, then Maou Beelzebub for your pieces." Riser says confidently.
"I guess this is goodbye then, Rias." Issei says, sighing sadly.
"I hope to see you again, Ise." Rias replies unhappily. Issei doesn't say anything for a few moments, before brightening greatly.
"Hey, don't be sad! I will return, I still have to complete high school! At least, if you and Sona allow it! And, I am still a part of the Occult Research Club, aren't I? This isn't goodbye, this is just a see ya later!" Issei says confidently. Rias nods happily, smiling at the fact that Issei wasn't totally abandoning her. Akeno also smiles, and Koneko lets out a small smile. Issei walks over to Riser as a red magic circle appears under the two men, Asia and Yubelluna having left moments before. Just as they disappeared, Rias heard Issei ask a question.
"So, are the rest of your peerage members total babes too?" He asks, a lecherous smile on his face. Riser smile the same smile.
"Oh, you have no idea Omoto." Riser laughs, and the two vanish. Koneko shakes her head.
"...Perv. I think that I will miss him." Koneko says flatly. Rias, Akeno and Kiba all nod, agreeing. They would miss the honest, lovable pervert.
And that is a wrap! I have been in to DxD for years, and this is something that I have never seen before, and wanted to see dearly. Now, I know that realistically, this could never happen, not even in DxD. However, as this is fanfiction, I don't care all too much. Ciao!
Edit: It was pointed out to me (Thank you TheBlindSalmon) that there were some issues with Issei's age, and etc...This should fix it, but I'll have to adjust some things I had in mind for the future. Oh well. What is an aspiring writer if not adaptable.
