Chapter 1: Meet Uzumaki Naruto

Uzushio, Capital of the Uzumaki Family Territory, Underworld

Everything was peaceful in Uzushio, the merchants were selling their wares, the guards were patrolling and the Uzumaki Mansion stood proudly in the outskirts of the city in all its glory. The peace was interrupted by a female voice that came from the Mansion.

"UZUMAKI NARUTO! WHEN I GET MY HANDS ON YOU, YOU'D WISH THAT YOU WERE NOT BORN DATTEBANE!"

The cry made the birds in the area fly away in terror while all those that heard it were smiling. Their young heir was up to his usual antics. The boy was the joy of all of Uzushio, always smiling and full of energy. He was always running all day all over the city pulling pranks and turning his poor mother's hair white. The irony of it never escaped their minds since two hundred years ago there was another ball of energy running around and terrorizing the population.

Inside the Mansion a blond boy was running as if God himself was after him. He was around eight years old, with deep violet eyes. After him was a woman that looked to be around her early thirties. She had vibrant red hair coupled with the same violet eyes as the boy. She was currently holding a frying pan and her face displayed a furious expression. The boy's name was Uzumaki Naruto and the one chasing him was Uzumaki Kushina, his mother.

The reason for this furious chase was the state of the main hall. Orange paint was covering every spec of the room, at some places not even dry yet, pooling on the floor. When Kushina walked inside she had a major freak-out, thus chasing after her son.

As Naruto made to turn a corner he missed the glint in his mother's eyes. Suddenly chains made of magic erupted from the ground around him entrapping him in an impenetrable cage. The young boy knew he was caught and so he pouted in defeat as his mother finally reached him.

"Mother! No fair! No chains when you're chasing me!" after his comment the chains receded a bit. Thinking that perhaps he wasn't going to get scolded he tried to slowly make a tactical retreat, yep that's what it was he said to himself in his mind. Uzumaki never retreated. They just advance in the opposite direction. And now the safest direction was as far away he could before Mt. Kushina could erupt.

"UZUMAKI NARUTO!" Of course he wasn't that lucky since the next moment a frying pan descended upon his poor head, making him see black.

When he next came to, he was met with his mother's knight Astolfo a petite girl, who was descended from a famous knight of Charlemagne.

"Auntie Astolfo! What happened?"

"Master Naruto, you're awake! Good, Master Kushina tasked me to oversee your punishment."

At Naruto's fearful look she elaborated. "Nothing too strenuous this time. Master is busy and she only assigns long punishments when she's here to oversee them. You only have to clean up the hall of the paint."

Naruto was relieved at his light punishment. His punishment usually came at great personal hurt. Usually he had to clean up the mess he made, then apologize to the servants for all the stress he causes them. Then came the dreaded part. His mother has him stay outside all night training. To an outsider it might seem harsh for a mother to subject her child to something like that but for Kushina that was normal. Ever since she lost her husband Minato to an assassination attempt she became extra protective to Naruto. So she had him training at almost all times to not have a repeat of what happened to Minato happen to Naruto. Though it seems that today his mother was busy with something and he escaped the worst part of his punishment.

"Auntie, do you know what has mother busy? She usually never leaves my punishment to others."

Astolfo smiled at him gently. "I'm not sure. I believe that it has to do with some guests we'll be receiving today. So the room must be cleaned by time for dinner." Seeing him freeze she decided to add some incentive to make him work quicker. "Tell you what. If you finish with time to spare I'll give you a ride on Swift." Swift was Astolfo's hippogriff, whom young Naruto adored.

"Yay!" seeing him get up and start running to the Main Hall had her laughing at his enthusiasm.

One of the 72 Pillars of the Underworld Uzumaki was always a strange Family. One of the smallest but more powerful ones, they always remained neutral to great conflicts that arise in the Underworld. During the Great War they isolated themselves by usage of their Sealing Magic. They remained out of the picture and so they were one of the few families that got out of the War unscathed. During the Civil War they remained neutral but secretly they were supplying the New Satan Faction with seals of all kinds. They have a good working relationship with Kyoto and the Youkai faction since the days before the Great War, when the founder of the family defied the original Lucifer and wed a Kyubi from Kyoto, thus making the Uzumaki family the only non-youkai chakra users in the world. They also have a great relationship with the Sitri Family due to their lines often intermarrying. Today the Family is led by Kushina who was wed to Namikaze Minato the leader of the Extra Devil Familly the Namikaze.

Eight years ago the Heir, Naruto was born. Unfortunately when he was a mere hours old, assassins hired by the Old Satan Faction attacked the hospital, with the intent to eliminate both the mother and the child of the Main Branch. It was close but in the end the father of the small family sacrificed himself to save both his wife and child, making Naruto an orphan from his father's side. The attack made Kushina overprotective of Naruto and had him trained as soon as she could without harming him.

That brings us to the present.

Naruto managed to finish cleaning up the Mansion just in time to go and prepare for the guests that were to arrive. Apparently today he was to meet a family from the 72 Pillars named Sitri. Naruto has heard about them before. The Sitri family apparently were a long standing ally of the Uzumaki with familial ties with them since every generation a Sitri-Uzumaki wedding happens. Even his mother was contracted to marry a Roland Sitri before she met his father. But Roland was one of the casualties of the Civil War so the contract was void, and by the time that a suitable replacement was found Kushina was already engaged to Minato. The Sitri family was known for their mastery over water magic, a trait that was passed over to the Uzumaki, and those last two hundred years for giving birth to one of the Four Satans, Serafall Leviathan.

Naruto had met with Serafall in the past since she was one of Kushina's oldest friends, and had the habit of calling her Sera-nee-chan as she insisted that she was too young in her opinion to be called auntie. Apparently that's how you called a big sister in Japan according to Serafall who was enamored with the Japanese culture.

Just as Naruto was finished getting ready there was a knock on the door. After telling the person to come in it was revealed to be his mother.

"Mum? I was just now on my way down."

"Naruto, may I speak with you?" she asked him with some hesitation in her voice. At his nod she continued.

"Naruto do you think I'm harsh?" That question surprised him greatly since he'd never seen his mother in such a mood. She usually was loud and confident with doubts having no place in her mood.

"Mum what're you talking about? You're the best!"

Kushina smiled a bit at his enthusiasm, at times her boy was so much like her in her younger days. "But I'm so harsh with you dattebane. I always punish you when you're doing pranks, and I always train you to the ground. I'm not here all the time leaving you alone for great lengths of time." By the end of it she had unshed tears in her eyes. Naruto in the beginning didn't know what to do. In the end he was just an eight year old boy, so he chose to respond in the only way that he knew. He just went over and hugged his mother.

"Mum, you're the best mother I could ask for. I know that after the death of dad things were hard for you, but you still gave me enough love for the both of you. And I know that you care, because after all the times that you trained me too hard you always stay next to me until you're sure that I'm okay." By the time that he finished they were both embracing one the other with tears in their eyes.

"Thank you, Naruto." They stayed as this for a few more moments basking in the others presence until Kushina remembered that their guests should be arriving any moment now.

"Now why don't we go and greet the Sitri's? Little Sona should be here as well. I know that you've been dying to meet her ever since Sera told you about her."

At the mention of that Naruto bolted to the door, nearly knocking her to the floor.

"DON'T RUN IN THE HALLS DATTEBANE!" everything was normal in the Uzumaki household.

Naruto couldn't wait to meet Serafalls little sister. The only friends he had that were his age was Rin, the daughter of his mother's contracted magician Aoi. Aoi was a woman that Naruto came to see a lot inside the mansion and she always brought Rin with her. The two were practically raised together.

A deep blue magic circle appeared at the reception hall of the Uzumaki Mansion. Through it four people appeared. Naruto instantly recognized one of them. Dressed in a pink shirt and a pink miniskirt was Serafall Leviathan, the self-proclaimed Maou-Shoujo with her long black hair pulled in two ponytails and her violet eyes twinkling mischievously. Next to her was a short bespectacled girl around his own age with a slim figure, black hair styled in a short bob cut and violet eyes. He guessed that this one was Sona Sitri, the little sister that Serafall won't shut up about, the Heiress of the Sitri Family. Behind them stood their parents, Lord and Lady Sitri.

"NARU-CHAN!" As soon as Serafall set her eyes on him she pounced, wrapping her arms around him in a big hug while smothering his face on her bountiful chest.

"Sera-nee-chan! Can't breathe! Let go!" at least that was what he wanted to say. What came out sounded more like 'Sff-ee-saaff! Saffs ffeef! Fffs foo!'

Taking pity on her son, Kushina intervened. "Sera, I suggest you let go. You're suffocating my son."

"AHH! Naru-chan! I'm soo sorry!" Taking deep breath Naruto fake glared at Serafall. "Sera-nee-chan I told you to stop doing that!"

"Mou! And I told you that I'm never stop doing that! Now let me introduce you to my parents and my little sister. So-tan come here." When Sona approached them she curtsied as is the custom in nobles.

"It's nice to meet you Lord Naruto." Both Serafall and Naruto looked at her with unblinkingly and then to each other as if to say 'is she serious?'. Both Kushina and the Sitri parents were watching them with interest to see their reactions.

Seeing that both her sister and the Uzumaki heir continued to look at her weirdly she couldn't take it anymore. "What? Why are you looking at me like that?

"So-tan you know we're in the Uzumaki territory?"

"What kind of question is that? Of course!"

"You know that the Uzumaki hate formalities right?"

"Wha-?"

"And also you know that Naru-chan here is family right? Like fourth cousin or something." she asked finally.

"Fifth cousin actually." Replied Kushina from the sidelines.

"So there! No need for formalities! Now try again!"

Sona kept grumbling about annoying sisters beneath her breath but she did as she was told. "Hello Naruto. My name is Sona. I hope we'll be good friends."

Naruto was almost in hysterics about Serafalls actions, but he returned the greeting with a big smile. "I'm Naruto. I hope we get along." His greeting was met with a smile from the bespectacled child.

"Why don't you two go and play. We'll call you when it's time for dinner." Said Kushina.

The only response she received was Naruto grabbing Sona's hand and running for the garden laughing all the while despite the girl's protests.

Naruto and Sona hit it off real well and by dinnertime they were completely exhausted. Naruto's more playful personality complimented well with Sona's mostly serious disposition. Of course having a sister like Serafall made Sona pretty resistant to any corruption Naruto could have inflicted on her. Still the pair hit it off, something that the parents were very grateful for.

Now it was right after dinner had ended. The two families were gathered in the living room of the mansion. Apparently the adults had something to say to both Naruto and Sona.

"Sona dear. What is your impression of young Naruto?" started the Lady Sitri.

Sona was puzzled by the question but answered nonetheless. "Naruto is a mischievous, playful ball of energy with not a single ounce of respect in his body," started Sona, making Naruto slump in his seat, pouting. "But he's quickly becoming a good friend." She finished with a smile in her face. In his seat Naruto brightened up and smiled at Sona who in turn stack her tongue out at him. Seeing them both interact like that brought smiles to all the adults.

"Naruto, now can you tell us your opinion for little Sona here?" said Kushina to her son.

"Sona is a stick in the mud." Everyone around face faulted except Serafall who fell of her seat by laughing so hard. "She's too uptight, and has no idea on how to have fun, wanting to only play chess. But I can corrupt her. Kukukukuku, she'll join the dark side. Beyond that she is my friend." Everyone was creeped out by his laugh all wondering how an eight year old can make a creepy sound like that. Except Sona who was extremely annoyed by him, with several tick marks on her forehead.

Still annoyed at her friends comments Sona turned to her parents. "Why are you asking us those things mother?"

The parents and Serafall looked uncomfortable at her question. In the end Lord Sitri turned to his daughter. "Sona are you familiar with the relations between our two families?" at his daughter's nod he continued. "Our families are deeply connected between them with blood ties. It goes back to the age of the original Lucifer, I won't bore you with the details but we, as in me, your mother and Kushina decided to enter you into a marriage contract."

Sona was in shock and Naruto wasn't far behind. Sona already knew what that meant. Earlier that year her best friend, and big rival, Rias came to her in tears to tell her that she was engaged to be married to Riser Phenex third son of the Phenex Clan, one of the other Pillar Clans. She believed such a fate would never befall her, since she knew that her parents despised arranged marriages. Now here she was, hearing the impossible.

In near tears she asked the one question that mattered to her. "W-Why? I-I t-thought you hated them." she shouted not caring anymore about maintaining her composure.

"The idea was mine." Came the answer from the most unexpected source, Serafall. The Satan was sitting there with the most serious face that she had ever seen appear in her sister.

"S-sister? Why?"

Serafall came in front of both of them and knelt coming to eye level with both children. She took her sisters hands in her own and then did the same with Naruto whom she had come to care almost as much as her little sister.

"Some months ago Sirzechs came to me and told me about Rias getting engaged to Riser Phenex. While the union was done for something ridiculous as pureblooded grandbabies, I knew that it was something that many would attempt through you So-tan to get closer to me. So I brought my worries to Kushina, and because she feared someone would try the same to Naruto to get an in in the Uzumaki, we devised this plan." Kushina continued for her.

"The contract between you two was worded in a way that could be broken very easily. But at the same time it's ironclad. It's a marvel really, I've known Sera for many years but I didn't know she could have such a good grasp of politics. Sona only you and Naruto can break the contract, no me not your parents, not even the Four Satans can. It'll be sealed by magic using the Uzumaki Clan Seals. Basically the contract protects you both from the other families and gives you the freedom for when the time comes to choose on your own, whom you'd want to marry. Be it each other or someone else. No one here will pressure you to do anything."

"Though we'll like it very much if you'd get married to each other it'll always be your choice." Added Lord Sitri.

Both Naruto and Sona calmed down considerably since hearing the reasons. "But we can break it off any time we want?"

"I'd suggest that unless you find lovers that you keep the contract intact. I know that you were terrified of something similar to what happened to Rias happening to you." Added Lady Sitri.

"Now why don't you sign?" asked them Kushina who started to prepare the Seals needed to make the contract effective.

"Okay mother/Lady Kushina." Both children said in unison.

Kushina couldn't resist adding one last shot to her son. "And Naruto don't worry, Rin would be understanding. After all devils practice polygamy."

All that was heard in the surrounding city was a loud. "MUUUUUUUUUM!"
