If asked, Naruto's family would find it difficult to give any specifics about Naruto in any capacity. This would be because in the first ten years of his life he was almost completely overshadowed by his twin sister, Rias Gremory. This wasn't completely without reason though as Rias' latent power gained through her mothers side of the family, the Power of Destruction had shown very early in her life and many of her family members dedicated all their free hours to helping her master it. They had spent far too much money on property reconstruction and renovation.

In the present day a ten year old Naruto stared at his older brother, Sirzechs Lucifer in confusion. Standing at 4'7, his spiky Blood Red hair tilting slightly with his head while his purple eyes, reminiscent of his mother sparkled in confusion. In his hands he held a thick book and he was in track pants and a short sleeved shirt with a collar that had a splotch of ink on it.

"What is this?" Naruto asked in confusion. His soft voice thick with confusion.

In front of him stood a nervously shuffling Blonde girl around the same age as him. Wearing a fairly dirty and torn kimono, oh, did I forget to mention the fox ears and one fluffy tail she also had?

"I got her so that she could be your first peerage member" Sirzechs said cheerily to try and mask his nervousness at nearly forgetting about his only brother while getting his sister and rare and hopefully powerful nekoshou for her peerage.

Of course the current Lucifer did feel bad about that. And giving his brother a one-tailed kitsune in such a condition due to being the only one he could find on such a short notice that fit his criteria.

"H-hello" coughing lightly and trying to conceal her blush she continued "I am Natsumi, it is nice to meet you. I hope to be a good member of your peerage" She said respectfully, even while fidgeting slightly.

Naruto looked over the girl and her dirty appearance. Rummaging through his pocket he found what he was looking for and grabbed out a Queen piece. Sirzechs looked at his brother in surprise, for a one-tailed Kitsune he thought his brother would go with a Pawn not a Queen!

Still speaking in a soft tone he instructed Natsumi on what to do and resurrected her into his Queen. After the piece was absorbed into her body he helped her onto her feet and with a brief nod to his brother lead her to his room in a far corner of the second floor and closed the door behind them.

Looking around in astonishment, Natsumi noticed the amount of space and how many books and scrolls lined the walls. On one far wall was what appeared to be a study desk with papers and random trinkets such as small stones and medallions. Moving closer to get a better look to satisfy her curiosity she noted how his handwriting looked both messy and organised at the same time.

"This is my notes on the differences between iron from the human world and the Underworld. I am interested to see if there are any developments" Naruto's voice sounded out from besides her, the sudden appearance making her yelp and jump back.

Staring at her quizzically he held out a pair of safety goggles "Would you like to help?" Blushing in embarrassment at her earlier reactions she meekly nodded and grabbed the plastic glasses.

Grayfia Lucifage was an extremely beautiful silver haired devil. The strongest queen of any peerage and wife of Sirzechs Lucifer. She wore a very form fitting maids outfit as she saw herself as a maid for Sirzechs. Quirking an eyebrow as her husband and king teleported into his office she spoke up.

"How did he take your 'gift'?" She asked respectfully as he sat down. Noticing his confused expression almost instantly, she spoke up "Is everything okay Sirzechs-sama?"

"Why would he use a Queen piece on a one-tailed kitsune?" Sirzechs mumbled to himself.

Grayfia froze in the middle of pouring tea for her King and though she did quickly recover she thanked her lucky stars that he didn't notice and only moments after placing a cup of tea in front of him, excused herself and left the room. Heading quickly, but formally and properly, to Naruto's room.

'Sirzechs-sama may have stopped me from training Rias' Queen piece but nothing was said about Naruto-sama's. I will make sure she is a Queen worthy of a Satan's brother' Grayfia thought as she reached Naruto's room.

Standing up straight she politely knocked on her door and heard a feminine voice mutter something similar to "I'll get it" and then the door opened to show a short blonde kitsune girl who seemed intimidated by her presence.

"C-can I help you?" She tried to ask politely but her own shyness made it seem a bit less polite than she may have been going for.

"That's good, a solid base for me to work with" Grayfia mumbled to herself "Greetings. I am the Queen of Naruto-sama's older brother. Do you happen to know that Naruto-sama's brother is a very important figure to Devilkind?" Natsumi meekly nodded "And that Naruto-sama himself is from a very influential family?" Natsumi nodded again but this time less confidently in her knowledge "Due to these factors I would like to teach you how to be a proper Queen for Naruto-sama. I will also be training you to grow stronger physically, mentally and magically as well so that you can be the best Queen possible" Grayfia said, offering to teach the young girl. When the young girl opened her mouth to reply the silver haired Queen quickly held a hand up to stop her.

"Discuss the offer with your King first. That is my first lesson" Grayfia instructed.

Nodding in confirmation the kitsune girl shut the door and after a minute or two of mumbled words that Grayfia couldn't make out the door opened again to show not only Natsumi but also Naruto.

"Naruto-sama, I believe you have heard of the offer I gave your Queen?" Grayfia asked as she mentally took note of Natsumi's nervous shuffling at being stuck between her King and the intimidating Queen.

"I have. I certainly wasn't expecting the proposal but I have no problem handing Natsumi to you occasionally. How often do you believe you can train Natsumi?" The soft spoken boy asked.

"Once every 2-4 weeks for 24 hours at a maximum. Though I am pleasantly surprised you agreed so easily Naruto-sama" Grayfia commented.

"Yes, well. I have seen how a Queen can act when given complete freedom and absolutely no discipline" Naruto said, thinking about his sister's Queen: Akeno.

Grayfia nodded silently, knowing the girl in question that he was refering to while poor Natsumi looked subtly between the two in confusion.

"I currently have no duties for the next 12 hours of the day. If you do not mind I can begin Natsumi's training immediately" Grayfia supplied, upon receiving a nod from Naruto she silently lead Natsumi away from the boys room while said boy went back inside.

Arriving at a small meadow outside the Gremory Mansion, Grayfia had Natsumi stand in front of her while she used a basic spell she had learnt long ago to summon a magic chalk. Said item allowing her to write on the air like it was a solid surface.

"Now Natsumi, I understand that at first these lessons may seem intimidating but eventually you will thank me for making you a worthy Queen" Grayfia started off the lesson, continuing as the kitsune girl nervously nodded.

"Now, how much do you understand about being a Queen to a devil peerage?" Grayfia inquired.

Gulping in nervousness she spoke up "N-not much G-grayfia-sama" She internally berated herself for the stutter.

"Understood. A Queen is a King's right hand. There ultimate partner and their closest confident. The traditional structure of a Peerage that many Devils have already forgotten is that each piece holds an important place, especially in combat. Within combat the pieces work as such; Pawns are generally, but not always, the quantity over quality warriors but can also act as secret trump cards if necessary, they are the most adaptable piece. The Rook is the "Tank" of a peerage, they can receive and deliver high amounts of physical and magical damage, though this increased strength means a decrease in speed and agility. Knights on the other hand suffer from the inverse problem. They have increased speed and agility but other than that their physical capabilities are lacklustre. Bishops are the "mages" of a peerage, their magical abilities are increased while their physical capabilities are kept the same or decreased to compensate" Pausing to make sure Natsumi was listening she continued "Finally the Queen piece, You and I. We have all of the increased attributes of the Rook, Knight and Bishop though in exchange for having all of the abilities increased they are increased to a lower level than an individual piece. An example is if a Queen and Rook have equal physical strength before being reincarnated, after they reincarnate they will both have increased strength but the Rook will be far stronger" Grayfia explained. Looking toward Natsumi to make sure she understood.

Natsumi nodded as she stared at the floating words that Grayfia had written while explaining as she tried to commit them to memory. Though she did notice that as Grayfia explained these things she seemed to genuinely enjoy doing so, a small smile now stuck on her features.

"Now as Naruto-sama's right hand you will be in charge of his general wellbeing but also making sure that he is disciplined and does his work. If you're lucky he will be the opposite of Sirzechs-sama and do his work without several severe consequences though if by chance Naruto-sama is the same I will teach you how to adequately deal with his lack of motivation, this is a generally well working method and there are others, though I wont teach you about some until you're older" Grayfia instructed getting a shy nod from the girl "Now stand up" Natsumi scrambled to her feet "The first thing we will be working on is your confidence"

Natsumi gulped as Grayfia's eyes twinkled

The next day Natsumi walked into Naruto's room with ruffled clothes and hair, something which she scowled internally at- her hair was supposed to be beautiful and fluffy dammit! Only to see him sitting at his desk in the corner of his room with his feet propped up on his desk while writing in a notebook, apparently having not noticed her entrance.

"N-naruto-sama?" At her hesitant stutter she cursed but had to stifle a giggle as Naruto jumped in shock and nearly fell out of his chair and quickly took his feet off his desk.

"Ah, Natsumi, you're back" He said softly as he tried to squash down the embarrassed blush that sprang up from her seeing him so informal.

"Indeed, Grayfia-san had to go back to her duties" She spoke, trying to stand up straight and speak professionally like Grayfia taught her to.

Naruto smiled lightly when he realised that Grayfia had already imprinted slightly onto Natsumi "You don't need to be so formal, I may be your King but you're also my right hand aren't you?" He asked while smiling slightly and tilting his head to the side.

Natsumi yelped slightly as a large blush lit up her face as he did this.

"I-I w-will try not t-to be so formal. B-but may i-I ask you d-do t-the same? G-grayfia-san said i-I am s-supposed to be your g-greatest confidant" She stuttered with a bright red face.

"An eye for an eye?" Naruto questioned and nodded "I can try to do that, would you like to help?" He asked as he held up his notebook.

Walking over to him, Natsumi saw the page was full of names of different supernatural species from around the world.

"W-what is this for N-naruto-sama?" She questioned as she tried to smooth down her hair and fur so that she would look more presentable.

"I'm looking at potential new members for my peerage" Natsumi's eyes widened at that.

"M-may I please borrow t-the notebook Naruto-sama? I-I would like t-to r-research the species y-you are looking a-at" Getting a gentle smile in return she felt the notebook rest in her palms and grabbing it carefully she smiled in return and began walking out of his room to visit the Gremory library.

"Please try to avoid my sisters Queen Akeno, she's around our age with long black hair and purple eyes. She's a bad influence" Natsumi nodded and softly closed the door behind her.

She quickly made her way to the library after having the embarrassingly ask a maid for guidance, her features set in stone, she was on a girl on a mission. She would, years later, thank Grayfia for not only instilling a strong protectiveness for her King but also for teaching her one of the most important lessons she would learn as a Queen; she was Naruto's first and last line of defence, and she would burn before she failed him.
