Timeskip 7 months
It's been a few months since Naruto started training in his family bloodlines. Today was Naruto's 8th birthday, therefore in the castle of satan the maids were running around the castle handling the decorations and our protagonist was with their parents at the gate of their castle waiting for the peerage of Minato's to arrive, Naruto was too exited as it been a few months since he has seen all of them together.
After a few minutes of waiting a large figure started to loom over the family as it soon descended you could see the purple scales on the body of the creature after it landed. One could describe its features as a fifteen-meter tall purple western dragon, with yellow horns on the top of his head, this was Tannin a member of the Minato satan peerage and ruler of the draconic mountain and a previous dragon king.
As soon as the dragon landed Naruto started running toward the dragon and jump to hang off his horn, after trying to get on his horn he gave up and started pouting and muttering meanie dragon, after watching the scene his parents approach and laugh at their son's antics.
"It's good to see you tannin how are your family and other dragons at dragon valley"
The dragon replies in a deep tone "They are fine Minato, the younger generation of dragon eggs are about hatch in a few weeks, therefore, it's busy "
After a few minutes of chatting with the dragon the bell for the front door rings and when the family opens it there was a woman appearing to be in her early twenties with silver hair and red eyes. Her hair, which flows all the way down to her back, features a long braid on each side with small blue bows at the end, while the rest is let down, ending in twin braids. She is seen wearing a black shirt with golden-caramel accents at the edges of the shirt that spread horizontally near the bottom, with two light golden trims going down the shirt; and the shirt splits slightly above her stomach, exposing her midriff. Around her neck and shoulders is a long, cyan scarf made from light material that reaches her hips. Her jeans are blue, with a white outline at the top.
This woman was Grayfia lucifuge queen and a daughter to Minato satan after the grayfia defected from her clan and join the civil war from the anti satan faction. After the devil was there was a lot of distrust for her because of her lineage from the lucifuge household who were servent to the Lucifer house, after the war grayfia ask to be a servant to the satan house because of being blood-related to the Lucifer clan which she was accepted and after a few years rather than treated as servent as she expected, Minato treated her as his daughter, which she was grateful for and after the making of evil pieces, he asked her to be her queen to make her closer to their family as they were unable to adopt her because of her being an adult and the many pillars mistrust in her.
Behind her were 2 black-haired girls, the first one was a girl with a little dark tan skin with black and blue outlines and she is wearing a black top and a brown skirt. She was Robin
Next to her was also a black haired girl but with light skin colour and black eyes with blue in the middle, She is seen wearing a Red shirt with golden-caramel accents at the edges of the shirt that spread horizontally near the bottom, with two light golden trims going down the shirt; and the shirt splits slightly above her stomach. She was Boa Hancock, they both were Mianto's pawns.
After seeing who was at the gate Naruto made a run for it and started shouting "Grayfia nee-chan", "Robin chan", "Nosey chan".
After seeing who was yelling all 3 had a different reaction Grayfia was happy to see her little brother, Robin was smiling to see her friend and Boa was angry to see him and started fuming.
After Naruto reach them he gave both Grayfia and Robin a hug which both returned and he stuck his tongue out at Boa which she copied.
After a few, he started bombarding them with questions as to how they were and what cool familial they got. To which Boa reply that he didn't need to know and that a man like him shouldn't worry what superiors like her were doing and just play around with toys at his age which led to a verbal fight between them, after seeing them go at it Grayfia and Robin look at each other and sighed.
After that his parents arrived and the fighting soon came to an end, after which they all went inside and sit down and started talking while waiting for preparations to be done.
Ms satan asks " So Grayfia how was the trip to find the familial for little Hancock and Robin."
Grayfia replied "The trip was successful both were able to find a familial of their choosing"
After hearing this Naruto perks up and asks "So what familial did u both get show me, show me"
Seeing as her chance to show off a little Boa decided to show them "Hmm my summon is the strongest and ill show you how cute she is " after which a satan symbol appear from which a white-colored hydra came out which immediately latched on to Boa and started rubbing against her.
Seeing a hydra everyone was impressed at how a child was able to subdue and form a contract with a hydra.
After that another circle appear from which blue-color small dragon, this was a sprite dragon a high-tier familiar, latched onto Robin and started hugging her.
Robin said "This is mine familiar I called her buffy isn't she cute "
Boa said " As if mine Salome is many times cuter "
Naruto "Wow I want one of mine own and when I get it will be the best familiar and that's a promise dattebayo"
After that both Boa and Naruto started arguing about how Naruto's familier wont hold a candle to hers
Seeing the kids play and enjoy themselves Minato couldn't feel more happier and as a smile tugged at his face, but after a smile a frown form on his face as he remember the day he found both girls few months ago .
Flashback 3 months ago
It was a normal day in satan household, where we find Naruto studying the histories and past wars with his uncle ajuka.
"Ahh it's so boring can't we just take a break or something ill fry my brain out like this"
"now -now Naruto if u don't study then you won't be able to reach your dream of defeating your father and sirchez "
" But I can defeat that stupid Mou already or did u forget how I made him fall into my trap he was even unable to leave his house after that for a month"
hearing that ajuka couldn't help but sweatdrop at the happenings of last month when Sirchez came to satan's house and was pranked by Naruto as how he added laxatives in his food and when he went to the washroom was tagged with condensed pink paint which changed his hair to pink because of which he was unable to leave his house because of humiliation he would have, after seeing the result everyone was laughing on his expense but at the Naruto was severely punished by both his mother and sister like figure Grayfia.
"Now Naruto why don't we get back to study to finish it fast so you and your father can go to the human world on a job request that your father said he will take you to "
After hearing that Naruto started studying hard to finish it quickly
Timeskip 2 hours
After finishing his study, Naruto barge into his father's office
" Father I finished my studies can we go to the human world now, I want to finish my first request fast as possible"
"All right Naruto get ready we will leave in a minute"
After a few minutes when the father and son duo were ready they were transported to the human world but before going there, Minato turned toward his son and said "Remember Naruto you will finish this contract this is for your own experience and I will interfere only when you are unable to handle the situation"
After saying that both father and son duo teleported.
Human world
Today was not a good day for Robin and Boa, first, the orphanage they use to live in was ransacked by some dark-winged creatures, and all the kids were taken by them. After getting kidnapped they were able to escape when they were transporting them, while running the road came to an end.
Both soon show a winged man's shadow looming over them, he had 4 greyish wings protruding from his back. After seeing him both sisters came to an end and started quivering and praying for whoever was listening to save them.
Both parties were unable to see a devil request paper behind them which started to glow, which got the attention of both parties robin and boa turn towards it with hope in their eyes to see if they will be saved, when light died down there was different reaction on both parties on the fallen was horror and fear at seeing the devil king himself Minato satan and on the girls were disbelief and resignation after seeing him thinking that he is also a normal human and won't stand a chance against that creature after glow died down Naruto ran towards the girls, while Minato remains standing watching the fallen and judging the situation.
"Are you two all right and what happening here can you pls explain"
Robin replied "We were kidnapped by that creature with our friends at the orphanage, we both were able to escape"
After listening to what both had to say Minato walk forward and asked the fallen what was their motive
"Our motive is non of your business devil king you should leave while you still have a chance or you will be dealt with"
After hearing this Minato summon a ball of darkness in his hand and send it flying toward the fallen which seeing it coming fallen dived towards the land where Minato was waiting for him with a sword of light in hand and cut his head off and let it fall to the ground.
After that Minato went toward both girls and knelt down on his knees to be at their level
"My name is Minato Satan and that's my son Naruto Satan. You both are brave girls to be able to escape from those fallen, now can you tell me what is your names and what place those guys take you to so I can rescue those kids"
this time Boa decided to reply "My name is Hancock and this is my friend Robin, those creatures took to that church on the Hill"
After hearing that Minato smiled and was about order his son to take them to a safe place and be with them, till he contact him, but at the same time, a few fallen attacked seeing the kids and the man that killed their brethren was off-guard, Minato immediately started fighting back with his power and defending the kids at the same time.
While this was happening 2 fallen with one pair of wings and a fallen with two pair of the wing made their way toward the kids, at the last moment before they could attack Naruto sensed them and by using his training was able to deflect the attack by creating a darkness barrier to protect them from the onslaught. after which like his father Naruto summon his dark light but rather than a sword he created a light spear in the sky and orders them to attack the fallen.
After thinking he distracted them Naruto went toward both girls to help them escape so his father can fight with full might and don't have to worry about saving them and keeping them safe, as all three kids were running to a safe spot the 2 winged fallen had enough of this and use his light power to deflect all of Naruto spear and destroy them, after that he uses his power to summon two massive spears and send them flying towards them.
After seing such a huge attack heading towards him Naruto was unable to summon a barrier or a shield to protect them from the attack which struck them and pierce through both Robin and Hancock killing them on the spot and the second spear struck Naruto in his abdomen which pierce half of his stomach.
Minato pov
Seeing his son being Peirce sent Minato in rage and he started killing Fallen with his all might, but it soon came to an end when he sense a huge increase in dark power coming from his son.
Which also stop all the fallen in their track at seeing such an increase as everyone turned toward the source in the middle of the energy blast stood Naruto with a light spear in his stomach which soon disintegrate and his wound started to heal after that dragon-like scale started forming on his body and harden his skin after the transformation was complete, his whole body was covered in dragon-like armor with his face looking of a real monster.
After seeing the transformation all the fallen got a chill up their spine of the power that creature was showing they all took a step back, but before they could run away a demonic voice rang from the dragonic creature.
"How could you kill innocents for your sick pleasure, they both were kids who wanted a happy family and you attack them and took their freedom i will END YOU"
After which Naruto summon katana of dark light and covered it with his darkness power and started running towards the fallen who were throwing attack after attack which were unable to penetrate through his armor .
After few minutes
It was a slaughter, there were parts of fallen everywhere.
After the genocide Naruto went towards both girl's bodies and knelt down, which led to his armor breaking apart leaving a crying Naruto, after a few seconds he fell forward with his eyes rolling above his head.
Minato pov
Minato couldn't believe his eyes his son unlock his dragonification transformation at such an early age due to the mental trauma of seeing someone his age die.
After seeing his son slaughter the fallen and then knelt to the dead girls crying and then fainting due to exhaustion.
He ran toward his son and caught him and made him lay down on the floor, after which he looked down upon the dead girls and an idea came to his mind, he use his power to summon his devil pieces, then started the process of resruct them into his peerage for his sons and those kids better. After finishing it he made a call to Grayfia and ask her to come to him.
After grayfia teleported to them was in shock at seeing so many fallen dead and looked like were brutally murdered, she then look around and saw her king sitting in an alley with Naruto covered in blood with 2 dark-haired girls lying near them. Grayfia made her way toward them and was in shock to see the condition of Naruto, how he was covered with fallen blood and not his which came as a relief to her.
After seeing the reaction on Grayfia, Minato quickly ordered before she could say anything " Grayfia I want you take Naruto and both those girls to the castle and take care of them, ill soon return after finishing the mission"
Getting her orders she quickly set up transformation circle she teleported all 3 kids to the castle to take care of them.
Underworld, satan's household
after grayfia teleported back to the house she immediately got the attention of the maids of the household. Some of them quickly ran towards the young Lord while the others ran to get the lady of the house, while others ran to get a doctor.
Grayfia and maids quickly set all kids on the bed and when lady satan, with the doctor, ran toward Naruto to get a better look at him.
After that doctor quickly started his medical procedure and check all three kids and turned toward the lady of the house and Grayfia.
" There is nothing to worry about Lord Naruto is only unconscious due to his body reaching his physical limit and having depleted his magical reserves and both the girls are fine and are in the process of changing into a devil due to the peerage system which is most likely Minato sama's"
After hearing that nothing bad had happened both took a breath of relief and then everyone went toward the main hall to sit down and talk about their condition while giving them rest.
After Nightfall
A magic circle appear in the middle of the hall from which Minato Satan came in, as soon as he came he was bombarded by questions from his wife, after settling her down.
"Dear pls inform us of what happened to Naruto and who those two children are and what happen in that request which cause Naruto to be in that state, you said it was an everyday request with minimum opportunity for danger"
"Yes Dear, I also thought it was a normal request as the power signature from the other side was weak of a human without any powers, but when we teleport there.
After that, he told them about the turn of events happen which led to the current scenario.
When he finished speaking both women, were holding their breath at hearing that Naruto unlock the strongest form a member of satan's house can achieve, which he unlocked at such an early age.
"Now Dear we have to take some precautions, first no one is to tell Naruto about how he achieved that form, I will inform him on his coming birthday till that time the matter would be cooled down and we have to increase his training even though he achieved that it was due to high emotions which led to him going berserk, after which his body gave up on him due not being ready, we have to make sure he doesn't use that form in any situation even If its life or death as there is a high possibility of him going berserk and attacking enemy and friend alike"
Both lady satan and Grayfia agreed to this seeing the reason behind it .
Next day
When Naruto woke up, he didn't remember much about the mission, but was told an edited version by his parents as how fell from exhaustion, after fighting. Afterword he met with both Robin and Hancock exited to finally have friends of his own age and also help them settle in the family and new life as devils .
Robin/Hancock Pov
After they both woke up they were scared after seeing their unknown surroundings, but after a few minutes when they saw the person who save them, they relax a little and were told of the situation as how they died were reincarnated into Devils and were told about the history of them. After listening to it were horrified that they were devils but were calmed down after the explanation that not all the history and storybooks were correct to depict them.
End of flashback
( AN: I am sorry if the flashback was too long I was thinking of dividing it into 2 chap but thought to do it this way)
As Minato was reminiscing about the past few months he was taken out of his thought by a summoning call from a paper and according to the emotion he was sensing it was of high importance after making eye contact with his wife and older peerage member, he got away from the kids and made a transportation circle and was teleported away with his queen on the high end request.
The End
Hoof this chapter took a tole to write on me this is probably the longest chapter I have written sorry for the delay in chapters, I am trying to better my writing and increasing the length of the chapters rather than uploading 1k to 1.5k per chapter to 3k to 4.5k per chapter.
Pls leave your review about this chapter and suggest some power for both Robin and Hancock as I don't want to use robin body parts clone powers it is too op and there nothing to say about hancocks as we all know devil work 7 deadly sins and fallen have fell for one those sins majority being lust which will mostly make her invincible in this universe
THANK YOU
