Story start:

It all started on the day that Lady Phenex was found to be pregnant and with not one baby but twins. The Phenex family was already big, and they absolutely couldn't wait for the new additions to their family. The fact that they'd be getting twins was amazing since after the last great war and the addition of resurrected devils, pure blooded devils were becoming rarer with each generation.

Everyone in the Phenex family could see the happy glow of their Lady as she walked down the hallway on the way to her and her husband's chambers with her stomach showing how close she was to having her twins since she was due any day now. Walking up to the door, Raven opened it slightly to see if her husband was in or not, and when she saw he wasn't, a frown marred her beautiful face. Her husband had been quite busy with the arrangements for the marriage between her now youngest son and the only daughter of the Gremmory family. Sighing softly to herself, Raven walked into the bathroom to freshen up before bed, and once done with that she stared into the mirror as she had done every night since she had found out she was pregnant.

The image she saw staring at her was that of a beautiful woman smiling slightly, with dark blue eyes and bright blonde hair. She had her hair done up in an ornate bun fitting someone of her standing among the devil community and had an angular face as did many pure blood devils. The most important part of her appearance, at least in her eyes, was her swollen stomach holding her beautiful twins.

"Honey, are you almost done in there? I'd like to see my beautiful wife." A voice was heard from the other side of the bedroom, and Raven could only smile since she knew that the only person who that could be was her husband Minato Phenex, the lord of the Phenex family, but most importantly, her husband. Sighing at her husband's impatience, Raven Phenex could only smile as she opened the door and apologized to her husband. "Sorry honey, but a woman's got to look her best for her husband, especially with all her competition."

Smiling slightly, Minato could only laugh while stating, "Honey, you know I might have a harem but you're the only woman for me. You're the woman that is the mother of my children". Many might not know this, but Minato was a tall blonde man, about 6'2" with spiky blonde hair and two bangs framing his face. He was currently dressed in red pajamas contrasting with his sky blue eyes.

"I'm just worried that you'll lose interest in me what with how fat I've become," stated Raven.

Minato could only just sigh while slowly pulling his wife to him until they were both lying on the bed with her head laying on his chest. There weren't any words that needed to be spoken between the two, they both knew that though the future might be a mystery, they would always have each other and their soon to be five children.

-X-(Three days later)

"AAAAAAAAAAHHHHHHHHHHHHH"

Standing beside his wife, Minato could only cringe as he felt the heat coming off his hand from the flames that Raven was unconsciously making and the unbelievable strength she was using to crush his hand. Thanking whoever his devil powers for making him basically fireproof, Minato could only smile down at his wife, and after looking at the doctor, he couldn't help but ask, "Isn't there any way we could speed this along or help her with the pain?"

Offering only a half-smile, the doctor could only sigh. "You know as well as anyone, Lord Phenex, that any kind of drugs given to her would be wiped out of her system in seconds thanks to the legendary healing of your family".

Not liking being ignored while she was having two babies forced out of her, Raven made her presence known by glaring at her husband and squeezing his hand until she heard a satisfying crack and shouting, "YOU ARE NEVER TOUCHING ME AGAIN MINATO. AND IF YOU EVEN THINK OF WANTING ANOTHER KID, IT'S GONNA BE COMING OUT OF YOU SO YOU CAN UNDERSTAND HOW MUCH I HATE YOU RIGHT NOW."

Grimacing at his most likely broken hand, Minato could only wonder how far his healing ability would be tested by his wife, who was doing her best to show that there had to be something he couldn't recover from.

"The first head is showing. Push, Lady Phenex," the doctor said.

Smiling slightly at his wife, Minato couldn't wait to meet his new children. He just knew they'd be perfect. Grimacing, Raven gave everything she had, and with a scream of "AHHHHHHHHHH", they finally heard the satisfying sound of the first baby crying. Cutting the umbilical cord and telling the proud parents that the first child was a healthy baby boy, the doctor handed him to a nurse wrapped in a blue blanket.

Turning back to the exhausted women, the doctor could only smile saying, "Good job Lady Phenex. Only one more and we're done. One more push and you will have your babies in your arms."

Smiling slightly, Raven could only give a brief nod before giving all she had left into one last push. "AAAAAAAAHHHHHHHHHH" and falling back down while hearing the cries of both her children.

Smiling and cutting the cord off the second baby and handing the second baby wrapped in a pink blanket to the other nurse so that she could be cleaned, the doctor left the room in order to give the two parents privacy with their children.

Smiling at his wife and kissing her forehead, Minato could only smile and ask "So we never actually decided on names. Do you have any idea?"

Beaming at her husband and gently taking her son from the nurse while watching the other nurse give her daughter to Minato, Raven could only smile while saying "For the girl, I was thinking Ravel and for the boy, I was thinking Naruto."

Smiling, Minato could only sigh at his wife's insistence on naming one of his children after a ramen topping though he supposed that the fact that Naruto meant Maelstrom evened it out.

Looking at their children the two proud parents could only wonder what changes would occur in the future and how their new children would get along with their siblings.

-X- (5 Years Later)

Running through the estate, Ravel and Naruto couldn't stop laughing. Throughout the years, the two had been inseparable with the servants knowing that if you saw one twin, the other one wouldn't be far away. They both had the blonde hair and blue eyes of the Phenex family. The only difference was while Naruto had short spiky hair, Ravel had her hair tied into two drill-like curls. They were both in their pajamas since it was getting close to their bed time.

With an indignant shout, the third member of this impromptu game of chase let his feelings be known. This individual was the third son of the Phenex family, and Naruto and Ravel's older brother, Riser. Riser was a blonde man appearing to be in his late teens and had the common traits of the Phenex family, except his hair was mysteriously colored a bright bubblegum pink.

"You'll pay for this you brats!" Riser shouted at the two little troublemakers

Still laughing, the two kept running, with Naruto shouting, "It's what you get for being a big meany to Rias."

Ravel could only smile at her brother as their latest prank had gone off without a hitch, only to be suddenly lifted off the ground with her twin and forced to look into the eyes of their father. Smiling gently at his kids and fighting the urge to laugh at his other son's new hair color, Minato could only ask the one question on his mind. "Is there any way I can get you two to come to bed quietly?"

Smiling at their father, the twins shouted in unison. "Can we hear a story!"

Looking at the twins, Minato could only sigh at their normal response, but he nodded nonetheless, and couldn't help but smile at the cheering of his youngest. Looking over at Riser and failing to hold in a chuckle, Minato could only smile and say, "I know they didn't mean any harm Riser and I'm sure that whatever they used will come out eventually."

Glaring once more at the two troublemakers and wishing they'd combust on the spot, Riser turned around as graciously as he could and walked off in the opposite direction.

Laughing once he made sure his son was out of hearing range, Minato once again turned to his youngest two who were still being held up by his arms and he could only sigh at the twin innocent looks he was getting from them. Slowly walking down the hallway until he got to a door labeled 'Naruto and Ravel's room, stay out', and putting down Ravel so he could open the door, he slowly walked in and sat on the chair that he used whenever he told stories to his youngest. Looking around the room as Ravel and Naruto got into their beds and gently tucking them in, Minato decided to tell them the story of the amazing battle he once witnessed between the old Lucifer and the combined team of Sirzechs and Grayfia.

Once he finished the tale, he could only smile at the pure awe that Naruto and Ravel were showing and when Naruto declared, "I'm going to be the next Lucifer!"

Feeling proud of his son's determination, and knowing that if anyone could do it, Naruto could, Minato could only ruffle his son's hair while saying, "I'm sure you will one day, but first, I think it's about time I taught you and Ravel how to use your devil powers. After all, what good are two future kings if they can't even protect their peerage?"

Smiling once again, Naruto could barely hold in his excitement. Finally, he would be able to get strong and protect those closest to him, especially his beloved twin.

Happy at seeing how excited his son was, Minato couldn't wait to start their training. However, he was surprised to see his only daughter so quiet. So, he couldn't help the frown that came to his face as he asked, "Ravel, honey, I thought you'd be excited to hear that you and your brother are finally going to be learning how to use your powers."

Looking up at her father, Ravel couldn't help but ask, "Dad, do I have to be a King? I really don't want to have that responsibility. I'd rather be a part of Naruto's peerage."

Looking over at his precious sister, Naruto couldn't help but smile. While he would rather have his sister be a king, he wouldn't be opposed to having her always be close to him. Smiling, Naruto asked, "But Ravel, wouldn't you rather have your own peerage?"

Looking at her brother and happy that he was so concerned about her, Ravel just shook her head and said, "While I'm sure I'd make a great King, I know you'd make a better one and I know we'll make the perfect team."

Watching the proceedings, Minato could only sigh. He knew his two children were inseparable and figured something like this would happen. He was starting to wonder if these two would rather just be attached at the hip. Regardless, he figured that they still had a couple of years until anything was set in stone, so, it was best if he just let things be and just be happy that he could start training the twins tomorrow.

Slowly kissing both of their heads, Minato turned to the door turning off the light while leaving the door open just a crack knowing how Ravel got if there wasn't some kind of light in the room. He could only sigh and wonder what awaited him tomorrow.

-X-(Next Morning)

The next day we find the twins sitting on the ground practically shaking with excitement while their father sat across from them demonstrating a simple fire spell for them to try. Watching them both, Minato was happy to see that his daughter was on her way to getting it, and keeping that smile, Minato slowly turned to his son. Seeing his son about to pour his power into the spell, he decided to give some last minute advice. "Remember you two, fire is a living embodiment. In order to channel the fire, we must pull out our power from deep within."

Nodding, Naruto started looking deep within. Looking over at Ravel, he could see a small aura of flame starting to surround her, which looked to be taking a lot out of her to maintain. With a burst of determination, Naruto looked deep within, and feeling his power, brought it out and felt the warm aura surround him and grow larger. Smiling at his accomplishment, he looked up at his father only to see him staring at him in shock. Looking to his left, he saw Ravel looking at him in awe. Finally, after a while, he couldn't help but ask, "What are you guys staring at? Ravel made fire too and you're not staring at her, dad."

Minato distantly heard what his son was saying. He was, however, more focused on the blue fire surrounding his son since there hadn't been a Phenex born with the power of blue fire in centuries. Smiling at his son, Minato couldn't help but think, 'Naruto, you just might be able to become the next Lucifer with that power'. Seeing his daughter also looking at her brother in awe and maintaining her flame for the entire time this was going on, he couldn't help but be amazed at her control and knew that one day these two would surpass everyone.

Ravel, however, was bouncing on the ground. She couldn't believe that her brother was able to change the color of his fire, and she could feel the heat coming off of it. She knew that her brother would be strong, but now, she knew that one day her brother would be invincible, and she would be standing by his side just like she always has.

Naruto, however, was in his own world smiling at the fire that he was using. His dream was to become a Satan and protect his family and with this, he was one step closer to that dream and while it may be a hard road ahead he would get there one step at a time and he would never give up.

-X-(Three Years Later)

It's been three more years and the twins were walking to Beelzebub's workshop since today was the day that they would be getting their evil chess pieces, though Ravel had opted not to get hers saying she'd much rather be a part of her brother's peerage as his Queen. Walking up to the large metal doors followed by his two youngest children, Minato knocked on the door, waiting for the famous Beelzebub to open the door so he could ask Naruto the questions before he got his pieces.

Slowly, the door opened and out stepped the Blue Satan wearing an apron and looking like he just had one of his experiments blow up in his face. Smiling slightly at the head of the Phenex clan and what appeared to be his two youngest children, Beelzebub asked, "What can I do for you today, Lord Phenex?"

Smiling and ruffling his son's hair, Minato answered, "Well Beelzebub, my son here is ready to get his evil chess set and while my daughter could get hers too, she has requested to be Naruto's Queen instead."

Smiling at how close the two must be for the boy's sister to want to be a part of his peerage and for the boy to be willing to give up his strongest piece to his sister, Beelzebub nodded his head and motioned for them to come inside. Once they were inside, Beelzebub looked at Naruto and stated, "Okay Naruto. I'm going to ask you a few questions before this gets started since it will help me determine how your chess set will react when you accept the King piece."

Nodding at the blue Satan, Naruto simply waited for him to ask his first question.

"What will your peerage be to you?"

"They will be my family."

"What do you use your power for?"

"To protect those precious to me."

"Okay, last question. What is your dream?"

"To protect my family and to become the next Lucifer!"

Smiling slightly at the very exceptional boy, the blue Satan turned and put Naruto's answers into the computer. There was a flash of light, and they all turned to look at an assembly belt where a red chess set suddenly appeared. Motioning for Naruto to move towards it, Beelzebub smiled when the boy walked up to it and the King piece floated in the air before floating into the young Phenex's body.

Smiling at his son, Minato couldn't wait to see what different kinds of people he would fill his peerage up with and wonder what the future would hold for his family.

Chapter End

This is my first story so please go easy on me. I was just tired of having to wait forever for new chapters to come out for this specific crossover and figured I'd try my hand at making a story (that being said I'm in it till the end I don't like non completed story's). Yes, I did change this somewhat mostly just me switching Lady Phenex's name to Raven sorry about using Rias moms name I originally wanted to make him Rias's twin but decided against it since there are multiple of those but none with Ravel. I also know my grammar isn't the best the problem is I don't see the mistakes since I'm so used to it I probably need someone to proofread it but that's a battle for another day. I'd also like to say for the pairing I genuinely don't know I'm tossing back and forth ideas mostly I want Naruto to have pure blood kids and I kind of want this to remain a single pairing so most likely Rias, Serefall or Ravel. The final note is I actually have the peerage decided on and while it might not seem necessarily accurate with pieces to power I'm making Naruto strong so it should equal out.
