This was inspired by several stories of Naruto being born in the Phenex clan. Now, normally it isn't an issue but since almost all stories about Naruto Phenex never go pass the 5th chap. So here's my story.

The underworld, a place where the human souls of the damn were sent for commenting the most sinister sins. A chaotic and vile place that made all the disgrace souls suffer for all of eternity in brims of fire, torcher and such. And the rulers of this world were the hideous creatures that feasted on such souls, they were the Devils.

Of course, that is what the bible that the God of Christianity used to describe the realm of darkness. Devils are, in fact, very human looking creatures except that they were immortal beings with demonic magical abilities and other traits.

To the devils, the underworld was their home and was nothing like what the holy bible has describe it. The underworld actually had forests, cities, towns and such, no ocean. But of course, there is an order where all the devils were ruled by 4 very powerful, very great devils known as the 4 Great Satans.

But below these Satans, there exist 34 noble families. Before there was 34 there have been 72 families known to all as the 72 pillars. The reason there are now 34 families is because most of the other families have perish from the Great War fighting against both God, and his Angel faction, and the Fallen Angel faction known as Grigori.

Now among these family exist a unique family who govern both fire and wind, whose bodies were similar to the legendary creature of immortal. The family is known as the Phenex family, named after the great Phoenix of legend.

In this family, there was one interesting child who was still deep asleep in his luxurious bed. Although as he slept he was starting to wake up because of an annoyance. The annoyance being that someone was pounding on his bedroom door.

As he continued to ignore it, his bedroom door open to reveal a young girl no older than 3 years old. She had dark blue eyes and blonde curly hair. She wore an elegant toddler size dress.

Once inside, she toddled her way towards the bed where she climbed on it. She then made it directly towards the center where she then started to jump up and down on it.

"Nii-san! Wake up!" She repeated several times before the young boy finally rose from the bed.

"Alright, alright, Ravel… I'm up, I'm up…" the older brother replied

"Come on Naruto-niisan, it's time to play!" Ravel cheerfully said

"Ok ok… but first let me get some breakfast." Naruto said

Ravel nodded in agreement as she hopped out of bed and left the room. Being fully awake now, Naruto decided to get out bed, freshen up, and get some breakfast. Walking over to his private bathroom, he got himself ready.

Naruto Phenex is a young 7 year old blond boy and is the fourth son of the Phenex Family. Naruto's room is a large room that is big as an apartment studio. It had all the basic furniture such as a desk, cabinet, drawers, bookcases and a, the current, home entertainment system, along with his bed and bathroom.

Once he was freshen up, Naruto was wearing his regular type of clothing, an orange short sleeve shirt, blue shorts, and a pair of sneakers. Walking out of his room, he glanced at his radio clock to see that it was 10 in the morning.

Evening

After a day of entertaining Ravel, Naruto and his little sister walked towards the dining hall for dinner. Once he had breakfast, Naruto found Ravel where the two hung out for the day, doing whatever Ravel wanted to do. Playing both physical and strategic games, Naruto was glad that the day was over since playing with Ravel was fun but still tiring.

Arriving at the dining room, both spotted their family. Sitting at the head of the table was their father, Lord Phenex head of the Phenex family. Sitting on his right side was their mother, Layla Phenex, also known as Lady Phenex. On his left, his oldest brother, Ruval Phenex, the current heir of the Phenex family along with his wife. Sitting next to their mother, was the third eldest brother, Riser Phenex (age: 15).

There entire family had waited for the youngest children of the family where they made their way towards their respected seats. Naruto sat next to Ruval's wife while Ravel sat next to Riser. Once everyone was at the table, the family had dinner.

While eating, Naruto could see that his father and mother were, secretly, eyeing him for some reason. Naruto knew that out of all the members of the Phenex family, he was the most different, appearance wise. Like the rest of the Phenex family, he had blonde hair, but his was wilder and spikier and had ear-length bangs framing either side of his face unlike the rest of the men in the family whose hair was short and tamed. Along with the hair, he had sapphire eyes while everyone in the family had dark blue eyes. The biggest difference between him and the rest of his family was that his face. His brothers looked like their father with some bits of their mother while Ravel looked exactly like their mother with a few characteristics from Lord Phenex, Naruto didn't.

Finishing dinner, Lord Phenex got his family's attention where he looked at his youngest son.

"Naruto, tomorrow you'll be coming along with me and you mother." Lord Phenex stated

"What do you mean, father? Where are we going?" Naruto asked

"You'll be coming with us to visit the Gremory family." Lord Phenex replied

"Why am I going with you two?" the young boy asking again

Lord Phenex explained that it was necessary for him to meet up with other devil families, just like his older siblings did when they were at his age. Naruto wasn't interested in visiting other families since he thought it was going to be boring since it was going to be an adult thing. His mother then told him that the Gremory has a young girl around his age, so he won't be too bored. After a bit of speaking, Naruto agreed where Lord Phenex told Riser to watch over Ravel for the day because Naruto was going with them.

Early Afternoon

Traveling using teleportation magic in a noble carriage, Naruto along with his parents made their way towards the Gremory manor. Being bored during the travel, the young blonde Phenex slept half way through the carriage.

He was suddenly shaken a bit as Naruto groggily opened his eyes to see his mother looking at him. Lady Phenex told him to properly fix himself since they're close to arriving to the Gremory manor.

Five minutes later, the Phenex family arrived at the front of the giant castle where they had an entourage to greet them. Stepping out of the carriage, they were greatly greeted by the guards, maids, and butlers of the Gremory family where they were then led into the mansion.

Entering in the castle's main entrance, Naruto saw several family members which he guessed was the Gremory family. Taking a good look, Naruto saw each member of the family in front of him.

The first was a middle-aged looking man with crimson hair and goatee. He wore a stylish white tuxedo with black shoes.

Next to him is a beautiful young woman in her late teens with shoulder length brown hair. She wore a cream colored dress that reached just above her ankles.

Standing, a bit, away from the two was another man who is quite handsome and has the appearance of a 20-year old who also had crimson hair.

By his side, another beautiful woman appeared to be in her early twenties with silver hair and matching eyes. Her hair flowed all the way down to her back and features a long braid on each side with small blue bows at the ends. She is wearing a blue and white French maid outfit with long sleeves and a white maid headband over her head. The only added visible feature was the red lipstick on her lips.

The only person that caught Naruto's attention the most was the one that looked to be around the same age as him. A young girl with crimson locks, like the men, that reached her shoulder blades and is wearing a cream colored dress like the brunette woman.

Walking up to them, the older looking man walked up to the Phenex family. "Greetings my friends of the Phenex family. I hope you had a safe trip here?" the crimson hair man greeted them.

"Greetings to you, Lord Gremory and Lady Gremory." Lord Phenex happily replied, "The trip was pleasant." He answered

Lord Phenex then turned his attention to the other crimson hair man, "It's an honor as always Lord Lucifer."

"It's a pleasure as well Lord Phenex. Although this time you seem to have another child with you. Who might this be?" Lucifer asked as he looked down at Naruto, who didn't showed any emotion.

Getting a quick nudge from his mother, Naruto walked forward towards Lucifer. Everyone was staring at the young blonde since he was going to be giving the current title holder of Lucifer and ruler of all the underworld his greeting which many believed was to be a respectable and proper gesture like any high-class devil would know.

Lazily lifting his hand, Naruto wave at Sirzechs, "Yo." He simply said

"…"

"…"

"…"

"Ow!" Naruto cried out as a visible lump formed over his head. Cradling his new headache, he looked at his mother, whom gave him a mild glare with a raised fist.

"Naruto… you're in the presents of a Satan… be more polite." Lady Phenex lectured lightly

Hearing this, Naruto straighten himself, coughed into his hand to clear his voice. He looked back at Sirzzechs, "Yo, how's it going?" he said as he lazily waved him back like the last time.

"Ow! Again? Why you hit me? I asked how he's doing." Naruto cried out as he cradled his now second lump on his head, curtsy from his mother.

Lady Phenex sighed as she shook her heard at her son's antics. Before she can even lecture her son again, the sudden sound of laughter could be heard ringing out into the room. All of the occupants look to see Sirzechs laughing and wiping away a tear, "Hahaha… I like him already!"

Lord Gremory coughed into his hand to both clear his voice and get everyone's attention, "Well… anyway… seeing as you introduced your son, I would like to introduce my daughter." Where his gazed moved towards the small red headed girl, "Rias… if you please." Suggested the elder Gremory

The now named Rias stepped forward, giving a lite curtsy, "Hello my name is Rias Gremory, I'm 5 years old and heiress to the Gremory family." Introducing herself to everyone

Lord Phenex looked pleased at this where he made his voice known, "Now with the introductions out of the way, I think we should get to the topic at hand." Where Lord Gremory agreed.

Deciding for a more comfortable setting, Lord Gremory led everyone towards to an appropriated room. Walking inside the meeting room, filled with table and seats, Lord Gremory offered seats to their guests which they happily accepted.

Once everyone was comfortable, both families looked at each other.

"Now let's talked about the topic that we discussed before." Lord Phenex started off

"Yes, the joining of our families." Said Lord Gremory with a smile

Naruto was really curious now, with his raised eyebrow being the only visible proof of it. Now despite being young, Naruto isn't stupid since he knew that the joining of two fanilies usually means one of two options; take over another family or arrange marriage between the two families, which he started to have a bad feeling about it.

"So it's agreed then, the youngest son of the Phenex family, Naruto Phenex, and heiress of the Gremory family, Rias Gremory, are officially arranged to be married." Lord Phenex proudly announced

3 years later

Outside the Phenex Manor, Naruto was lying on the ground, panting heavily, as he relaxed in the family's training area. Around him, the training area showed signs of destruction as there are disturbed mounds of earth, scars, and slices on the nearby wood or rocks.

Lying on the ground, he thought about what happened a few years ago.

Flashback

All of the Gremory workers/employees continued with their own assignment/chores when all of a sudden they all heard a loud voice all over the castle that stopped them for a moment.

"WHAT!"

In the meeting room, where both the Gremory and Phenex Families were in, looked over to see Naruto stunned face as he looked both paled and a ghostly figure of himself was leaking out his mouth..

"Naruto, what's wrong?" Lord Phenex bewilderedly asked

Snapping out his trance, Naruto looked back at his father with disbelief look, like why he was even asking that question.

"What's wrong? You just decided who I'm going to spend my life with." Taking a few moment to breathe, "… why me!?" he asked

Being quiet throughout the whole time looked surprise to see Naruto's reaction. Sirzechs looked insulted as he stood up and pound the table with both his hands.

"What do you mean by 'why me?' How can you reject my cute little sister, who is the cutest little girl in all the Underworld." Sirzches remarked

Naruto realize what he said where he looked at the leader of underworld, "That's not what I meant. I've got nothing against her, it's just… this situation I guess."

"Naruto…" the young blonde heard where he turned to see his mother's gaze, "… you have a chance here to unite two of the major families. Don't waste this opportunity. We're placing a lot of responsibility on you, so trust us." Lady Phenex finished with a small smile

"Oh yeah, marrying me off to a stranger… I feel so much better now." Naruto sarcastically muttered to himself

Lady Gremory decided to add something with a playful wink. "You never know… you two may come to like each other as more than friends."

Naruto was about to respond to Lady Gremory, but Lord Gremory quickly cut in, "Rias, why don't you take Naruto on a tour around the estate?" asking his young daughter.

The young crimson hair girl's face brighten up since she was getting bored in this meeting, plus she would also get the opportunity to make a new friend. Getting up and skipping over to Naruto, she literally dragged him out of the room by his arm, "Come on Naruto, I've got loads of places to show you!"

"Wh-what?" Is all he said before Rias started to drag him out of the meeting room, "No, wait? Gah! I wasn't finished yet…! HELP!" Naruto hysterically cried out as he was being pulled out of the meeting. He even made the attempt to claw in his fingers directly at the door where his fingernails clawed through the thick wood for all those to see.

Once they left, the adults shared a laugh as both Lady Gremory and Phenex muttered out, "Aww young love!" while both Father's couldn't help but pity the boy in a way since he now had a leash around his neck.

End Flashback

Ever since then, Naruto and Rias started to hang out with each other where they soon started to have a pretty good friendship between each other. Of course, it helped break the ice between them when they both shared an embarrassing secret with each other.

Flashback

Being led around the entire castle, Rias decided the first stop would be in her room. Naruto has stopped his attempts to free himself where he just settled on traveling with Rias. Entering the room, Naruto saw something that made him looked surprised/stunned at what Rias room was like.

All over the room, posters, movies, books with anime and manga stuff where pilled all over. Naruto looked impressed on the fact that she had this much anime and mange stuff, even though he never got into it much.

"So what do you think?" Rias cheerfully asked him, who was standing next to her.

Naruto simply muttered out, "Otaku…"

The moment he said that, he looked to Rias where she just suddenly disappeared. He looked around where he found the red head princess hiding under the covers of her bed.

"You probably think I'm weird… don't you?" Rias muttered from under her covers.

"Probably if I have standards. If anything, you probably be considered normal while I'm the weird one considering that I have a strong obsession for ramen and can eat 3 times my own weight of it." Naruto admitted to her.

Rias uncovered her head to look at the blonde boy where she looked at him curiously. He confessed that he was so obsessed with the food that his mother had to restrict him from eating so much of the stuff that he had to make secret compartments and such in order for him to have it as a secret snack or meal.

Hearing Naruto's confession, Rias started to giggle at him, "Your right… you are weirder than me…" she confessed to him.

End Flashback

Since that time, he visited Rias regularly where they both started to grow a really strong friendship towards each other.

His thoughts about his relationship with Rias stopped since he started to stand back up but barely. Taking another deep breath, he started to work on creating his new move, even though his body was screaming for him to stop training.

The reason why he was working so hard was because of a condition that he has that no one in his family has. Naruto Phenex, the son of the current Lord Phenex, didn't inherit both the flame and instant healing ability that the rest of his family had.

It was only after a couple of weeks from visiting Rias and the Gremory family that, during one lesson, from his mother they all found out something very disturbing.

Before visiting the Gremory family, Lord and Lady Phenex decided to start training Naruto in wielding his magic where he excelled in learning the basics of his demonic power.

During the lesson, Naruto got seriously injured where everyone believed that Naruto would instantly heal up since he was a member of the Phenex family, but to his family's shock Naruto wasn't instantly healing/regenerating from the injury into his shoulder.

Using Phoenix tears to heal him, his parents asked him to perform a fire attack where they showed him how. Naruto had tried several times, but he wasn't able to perform any fire attacks. Although he didn't perform any fire magic, he was able to perform strong wind magic that their family was also known for.

Being examined over, Naruto and the rest of the family found out that Naruto was the only Phenex that didn't inherit the Phenex ability of fire or instant healing. Naruto was sadden since he can't live up to the rest of his family's heritage but was surprise to know that he does have a healing ability in both his physical and tears.

Taking a closer look, Naruto's physical ability showed that he has a strong healing ability, just extremely slow where it would take several minutes for him to heal from a scrape on his elbow or knees. Longer for more serious injuries. Although his healing ability was slow, it showed to be a lot stronger where Beelzebub, himself studied both his body and his tears.

Naruto's healing ability might be slower than the rest of the Phenex, but it showed that he actually has an immunity/resistance to several strong poisons that would normally kill a devil such as the poison of the 9 headed hydra where even his tears also held the same type of quality, which makes it even rarer.

Phoenix tears can heal injuries such as severed arms or mortal wounds. However, Naruto's tears are a lot more special. Naruto's tears doesn't heal instantly like regular Phoenix tears, instead it restores/regenerates a person's body to being 100% back to health where even the loss of organs are regenerated while also healing the person from a very powerful poison.

It's because of this, that even Sirzech's Queen, Grayfia, personally suggested that Naruto's tears be made classified even to the elders/advisors since information leaks might cause problems for the young boy along with having a bottle of his tears in case of extreme emergency for the 4 Satans if needed.

With the secret of his tears being classified by everyone except to him, his parents and Lord Lucifer and Beelzebub along with their most trusted associates, every other devil family considered Naruto to be extremely weak and such.

He only ever heard of this during the parties that his parents were invited where he came along with them as their own acquaintance. Even though several head families and other high-level devils kept it quiet from him, he had incredible hearing where he heard that he wasn't anything special. Several times, he was tempted to reveal his secret abilities but had to keep it quiet.

He was also bullied by his older brother, Riser, where he teased and called him names as well as telling him on how much a disgrace or failure he was to the family.

Naruto was really depressed about it where Rias cheered him up where he learned about her cousin Sairaorg Bael. Hearing his story along with what he was planning on doing, he was inspired to the same thing where he spent the next several years on training himself to ground.

In 3 years' time, Naruto has completely changed as a person. Naruto has become a lot stronger as a person, physically, emotionally, and mentally. Naruto has learned to ignore all the taunting and such while only listening to the praises he earned through his hard work. He has grown to be a cunning and smart individual where he even defeated his friend, Sona Sitri, who he met through Rias in chess.

Although he was considered to be book smart, he was a prodigy when it came to combat. His martial arts skills were way above average where he trained with several of any of Riser's or other of his family's peerage members, being able to hold his own against Yubelluna, Xuelan, and Isabela for example. His skills in handling weaponry were also high up in the specs as he used either kunai, a katana, or chains.

His physical abilities where among high, his magical abilities is what made him be known as a prodigy. Unable to use his family's fire ability to either attack or fly since the Phenex family wings are fire, he learned from both his mother and father all the wind magic that they know which was few since the Phenex family primarily use fire magic in their fights while adding wind to strength it. Soon mastering the basics, Naruto focus on increasing them to new heights where he did everything to increase his strength along with also trying to find a better use in using his demonic powers.

In the three years, Naruto has surprised his family by creating several new wind attacks for himself such as Majesutikku kaze no ken o funsai (Crushing Fist of Majestic Wind). He also found a way to change his inability to fly when he mastered Shundo (Instant Movement). Instant movement allowed him to temporally increase his maximum speed by using his magic to triple it for a short burst where he used it to fight against his brother's evil pieces to win. With Shundo as the basis, he thought of the output where he then moved on where he mastered Koku Shundou (Void Instant Movement) to help him move in the air with incredible speed that he help him keep up with his own brother, Riser, when he sparred against him.

Lord and Lady Phenex had openly said to him that they were proud of their son adaptation since, even with the disability he was presented with, Naruto was able to improve through leaps and bounds to become a very strong symbol for the Phenex family.

Even though he was able to improve himself to greater heights, he knew that he needed more in order to fulfill his dream on becoming a Satan, which led him to his current time right now.

Naruto studied up where he learned about the demonic magic that every devil possess. However, no one knew what the purest form of the demonic magic does since all devils add their signature element into it. Such as Grayfia using her demonic magic to create Ice while Sona uses her to create water and so worth.

Naruto wondered if there was a way to create attacks with just the purest form of demonic magic without adding the element to it where he tried to figure it out. It wasn't till he recall from watching an anime show with Rias how the character used his 'ki' to create a ball, although mentally he thought about it since the ball of energy made him feel like he was familiar with it. This led him to see if he can do the same thing. For over a year, he's been working on creating his newest attack where he was able to get it started by using water balloons, rubber balls, and air balloons.

(Rasengan training)

Using the water balloon, Naruto used his demonic energy to pop it which took him over 2 months. Popping the rubber balloon was much more difficult where he pushed himself for nearly 5 months before he got it. Finally, the air balloon is where he was as he tried to control the demonic energy without breaking the thin material while pouring in 100%. So far, he hasn't made any progress where he was stuck for the past 3 months on trying to create his technique. He would ask his parents for help but Naruto wanted this to be a secret.

Just as he was about to try and perform his technique, a sudden pillar of flames appeared next to him. He wasn't bothered by it since he was use to his family making such a flashy entrance. Naruto waited for a moment before the pillar dissipated to reveal his mother.

"Mother… why are you here?" Naruto asked

"Your father and I have decided that it was now a good time for you to visit the Earth, since you'll have to go there soon if you wanted to find your future peerage." Lady Phenex

Naruto was surprise that he well be going to the human world. Getting over his surprise, Lady Phenex told him that he has an hour to get ready since she'll be taking him to the earth today where she'll be taking him to England.

Till Next Ch.
