Hello all Storm here with a new story! This is another story challenge from "The Sith'ari" and is a rarely done Naruto crossover and even rarer basis. So, without further ado.

I own nothing

Summary: On the night of Naruto's birth, Minato and Kushina were surprised to find that the latter also gave birth to a daughter when they were only expecting a son; a daughter that they decided to give a western name to for some reason, Mandy. But unknown to everyone else Mandy happened to be much more than expected. And by the time anyone could realize it, it would be too late to stop the Incarnation of Evil itself.

Mandy walks onto the center of a black screen and faces the readers.

"When there's no more room in hell, Mandy shall rise once more." Mandy said before walking out of view

It was a quiet night within Konohagakure, with most having already turned in for the day while Ninja still patrolled around the village. Though unknown to all but a select few, in a hidden location that's a fair distance away from the village, a woman was giving birth with two midwives and her husband present, with Anbu guarding the perimeter outside.

The woman in question was Kushina Uzumaki, the Jinchuuriki of the Kyuubi no Kitsune, and currently more pissed off than she's ever been in her life, along with the most pain. The source of her pain just so happened to also be the source of her anger.

Her husband Minato Namikaze.

"AAAAAAAAAAAAAAAAAAHHHHHHHHH! I'M GOING TO FUCKING KILL YOU, YOU BLONDE BASTARD!" Kushina screamed while also glaring at her husband, who laughed nervously as he also worked on keeping the Kyuubi's seal from breaking.

"It's gonna be alright Kushina, it'll be over soon." Said Minato, hoping to calm her down.

"SHUT UP! THIS YOUR FAULT, YOU DID THIS TO ME!" Kushina shouted.

"If you have time to curse your husband, then you have time to keep pushing." Said Biwako Sarutobi, while Kushina gave another scream as she pushed again, wanting the pain to end.

"Uh, are you sure she's okay? I've never seen her scream this much before." Minato said worried.

"It's perfectly normal, just focus on keeping the Kyuubi's seal locked, otherwise we'll all have something to scream about." Biwako said.

After what felt like an eternity to Kushina, the pain finally stopped along with her screaming, only to be replace by the sound of a crying infant.

'Naruto-kun.' Kushina thought, hearing her baby for the first time as tears fell from her eyes.

Minato was also stunned into silence hearing his son crying, it finally registering that he had a son, he was a father!

Unfortunately, the new parents weren't allowed a moment to enjoy the moment when Biwako spoke.

"We're not done yet, there's still another one." Biwako said, much to Minato and Kushina's shock.

"Another one?!" Kushina questioned, horrified that she'll have to go through that pain again and shocked that she was having twins.

They thought they were just having a son, not twins!

"Don't worry Kushina, you made it through once, you'll be able to handle giving birth a second time." Minato said encouragingly, only to pale when Kushina slowly turned her head towards him, her eyes now red with slit pupils and her hair starting to wave around like nine tails.

"I'm. Going. To. Murder. You!" Kushina said through gritted teeth, swearing to make him suffer for this nor ever let him get her pregnant again.

After a second round of screaming and cursing as Kushina gave birth once again, Biwako held a second infant.

"It's a girl." Biwako announced.

"Why… why isn't she crying? Is she alright?" Kushina asked both tired and concerned, since she didn't hear her daughter crying.

While it was a shock that she was having twins instead of just Naruto, she's still happy to have two children, a son and a daughter.

"She's fine, it's strange but not unheard of for some children to be born sleeping." Biwako said, before smacking Minato's hand when he tried reaching for his children.

"Don't touch! The mother always holds the children first." Chastised Biwako.

Walking over to Kushina, Biwako placed the twins beside their mother while Kushina smiling tiredly as she held her children, with both of them having blonde hair like their father. Their eyes were closed, but she knew they'd either be blue like Minato's or purple like hers.

"What should we name her?" Minato asked as he looked at his daughter.

They'd already agreed to name Naruto after the main character from his sensei, Jiraiya's, book; along with making the man Naruto's godfather. But they hadn't thought of any girl names given they weren't expecting a daughter, or twins for that matter.

Kushina thought about it, going through all the different names she could think of while looking at her daughter, though none of them seemed to suit her. That is until one finally came to mind.

"Mandy." Kushina said.

"Why a western name?" Asked Biwako, confused at the strange name choice.

Kushina gave a small shrug in response.

"I don't know, it just came to me. Besides, I think it seems to work, Mandy." Kushina said smiling.

"Yeah, I think Mandy is a good name too. Naruto Uzumaki and Mandy Uzumaki." Said Minato, nodding in agreement.

While the new parents were still confused on why they had twins, they were none-the-less happy and excited at having a son and a daughter. They couldn't wait to make new memories and moments with both Naruto and Mandy.

Though before the night was over, both parents will be cursing fate for being such a two-faced bitch.

*Later-Safehouse*

'Why can't I move?'

This was the first thought that came to Mandy's mind when she regained consciousness.

She couldn't move her body, in fact her body felt smaller than it used to be.

'If this is someone's idea of a joke. They're going to regret it.' Thought Mandy as she opened her eyes to take in her surroundings.

The first thing she saw was a giant woman lying next to her, making Mandy believe she was a giant, only to discard that thought when the woman looked at her surprised.

"Oh, sorry Mandy-chan, I didn't mean to wake you." The woman said with a weak smile.

If she could, Mandy would have raised a brow at the woman smiling at her; her, the Incarnation of Evil itself. Mandy was further confused by what the woman said next.

"Don't worry, your Tou-san will be back soon, he will keep you and Naruto-kun safe." Said the woman, before proceeding to wrap an arm around Mandy and something else.

Looking, Mandy saw a baby boy lying next to her, whom she guessed was this Naruto the woman was referring to.

Taking in all the information she has at the moment; Mandy came to the conclusion of what happened.

She's been reincarnated.

The woman was obviously her new mother, the boy, Naruto, is her new brother, her twin given they're both newborns, and Tou-san as Japanese for father, meaning her new father was off dealing with an apparent threat to them.

'I guess someone finally got tired of me in Hell.' Mandy thought boredly.

It wasn't surprising that some higher being reincarnated her, given the chaos she was causing in Hell.

Making demons run away crying with just her words, forcing Lords of Hell to do what she said, torturing damned souls, and just generally throwing everything into chaos in her bid to take over.

Closing her eyes again to go back to sleep, deciding there wasn't anything she could really do at the moment.

*Later*

Mandy opened her eyes again when she felt something dripping on her face. The first thing she saw was the redhead woman from before and a blond guy, her new parents, impaled on a giant claw inches from her and her brothers faces.

'Huh, that's actually a new one.' Mandy thought, when she saw the creature that had just killed her new parents.

A massive fox with nine tails, it easily dwarfed the size of any creatures she's previously seen in her past life.

Looking around, Mandy saw they were now in a forest while she and her brother were on what looked like an altar, and a barrier made of golden chains was surrounding them, chains that seemed to be coming from her new moms back. Mandy also noted the same chains were wrapped around the fox.

'This is all new.' Mandy thought, wondering just what world she was reincarnated into.

Her attention was turned back to her parents when she heard her mother talking.

"Naruto, Mandy...don't be picky eaters, eat a lot and grow big and strong! Take your baths everyday...go to bed early and sleep well. Study hard on your Ninjutsu...I was never very good at it...maybe you both will...everyone is good at some things and not so good at others...and if things don't go so well...don't get so depressed. At the academy, listen to your teachers. Make friends! It doesn't matter how many...just make sure that they're people you can really trust...and a few is enough! Regarding the Three Prohibitions of the shinobi, be careful when you loan and borrow money, make sure to save your missions pay carefully, and no drinking alcohol until your 20...too much sake is harmful for your body. As for girls Naruto...well...I'm a girl so I don't really know what to say...but sooner or later, you'll want a girlfriend and that's normal...just...don't fall for a strange one...try to find someone...like me. Mandy for boys…well… just… make sure you find one that truly cares about you…and make sure he's not a pervert like Jiraiya. Oh...one more thing...watch out for Jiraiya; and Mandy, feel free to castrate him if you see him doing anything perverted...dattebane! Naruto…Mandy...there's going to be hard and painful times ahead...take good care of yourselves...and always be there for each other! Find a goal...a dream...and don't stop trying until it comes true! There's...there's...there's so much more I want to tell you...to teach you...I want to stay with you longer...I love you both."

And now Mandy was completely and utterly confused. Not once in her entire life, and afterlife, has she ever heard anyone speak to her in a such a… loving way?

Her parents in her first life were afraid of her, as they rightfully should be; Billy was an idiot who didn't know what fear was, aside from a few exceptions; Irwin was a moronic flirt that thought he had a chance with her ever since that time Billy took control of her mind; and while Grim had some moments of showing genuine care for her and Billy, he was mostly just resentment at being their friend/slave.

So, to hear her new mother tell her and her brother all that, it left Mandy feeling confused and thankful that she was a baby, since she won't be required to respond.

"Sorry… Minato I took up all our time." Kushina said.

"Don't be. Naruto, Mandy...my words to you as your father...listen to your motor-mouthed mom." Minato said smiling, before making a single hand-sign.

"Eight Trigrams Seal: Seal." Said Minato

Mandy watched as the fox was split in half, the darker half going into Naruto and the lighter half going into her.

'Hm, so he sealed the darker Yin-half into Naruto and the light Yang-half into me. Well… this'll be fun when I'm older.' Mandy thought, now liking this new world that she's just been born into, since she already she has a giant monster fox as her pet, and she will make it her pet.

Kushina flinched in pain as she hit the ground, unable to move after giving birth twice, having the Kyuubi extracted, and being impaled on the fox's claw; it's a miracle she's still alive, despite her strong life-force as a member of the Uzumaki Clan.

Looking at her children, Kushina felt tears fill her eyes. Now she'll never get be there for them, never see their first steps, hear their first words, attend the Academy, become Genin, grow up and have families of their own. Now they're not even a day old and already orphans, while having a burden she never wanted them to have.

'I'm sorry, I'm so sorry.' Kushina thought, while cursing the Masked Man that did this.

"Well, well, look at this. How kind of the Yondaime to seal the Kyuubi into two helpless infants for me." Came a voice that Kushina despised with her entire being.

Looking up, Kushina saw the said masked bastard that caused all this.

"You! Stay away from my babies." Kushina said, wishing she had enough strength to summon her chains to kill him.

"Hmph, I have no use for you. Just lay there die like the rest of your clan, I have what I need." Said the masked man as he walked past Kushina and towards the twins.

'No! I won't let him hurt them!' Kushina thought as she tried to move, but her body wouldn't respond.

She wanted to shout, scream, anything to try and stop him, but she could only lay there and watch as he went to grab her children. Then the luckiest thing happened, at least Kushina thought it was.

A wolf jumped out of the trees, tackling the Masked Man away from Naruto and Mandy.

'Huh, I guess they want to raise me too.' Thought Mandy, remembering the time her old father admitted wolves had tried raising her as a member of their pack when she was born.

More wolves soon came out of the forest and surrounded the Masked Man, snarling and growling.

"Get off me, you worthless creature!" Shouted the Masked Man, grabbing the wolf by its neck and sucking it into his Kamui dimension.

The other wolves jumped at him, but this time he was prepared, and they phased right through him or he pulled them into his Kamui dimension, intent on dealing with them later. However, to the man's shock, bite and scratch marks started appearing all over his body. It dawned on him that the wolves he sucked into his Kamui dimension were attacking the part of his bodies that phased there when he avoided attacks from the wolves in the real world.

'I have to get away!' Thought the man, while panicking.

Unfortunately, he didn't have enough time to concentrate and teleport from the attacks in both dimensions.

As this was going on, the Sandaime Hokage and Anbu arrived at the scene and saw Kushina lying by Naruto and Mandy.

"Kushina!" Sarutobi said as he ran over to the woman, seeing she was still barely alive, while Minato was already dead, sadly.

Looking at the Sandaime weakly, Kushina pointed towards where the Masked Man was still being torn apart.

"Make sure… he… dies…" Kushina said, wanting to make sure the threat to her children didn't live past today.

Looking at the Masked Man as he was currently being mauled, Sarutobi motioned the Anbu to go forward. Nodding, the Anbu grabbed their swords with the wolves scattering, leaving the remains of the masked man, while one of the Anbu swiftly decapitated him, just to be safe.

"He's dead Sarutobi-sama. Thankfully the head's still intact." The Anbu said, with Sarutobi nodding as he took some morbid pleasure at the death of his wife's murderer.

"Good, bring the head to Inoichi, and have the remains brought to any available Medical Ninja. I want them to discover everything about this man, from his true name to what his goals were." Sarutobi ordered.

Looking back at Kushina, Sarutobi sighed in sadness when he saw she had died as well.

'What a mess.' Sarutobi thought as he sealed away Minato and Kushina's bodies, while having two Anbu carry Naruto and Mandy.

With that, they returned to Konoha. The only good thing that happened was that the one responsible is dead and soon they'll discover his identity in a matter of days.

*Amegakure*

"Madara is dead. He tried taking the Kyuubi's new infant Jinchuuriki and was mauled by a pack of wolves." Zetsu reported to Pein and Konan.

Both looked at the plant-like creature with blank expressions. They were processing the fact that "Madara Uchiha", the "Madara Uchiha" was dead, mauled to death by a pack of wolves.

If this wasn't such a blow to their organization, they'd actually feel amused at the irony. A legendary Ninja, known for crushing armies and bringing Kage to their knees, done in by a pack of wolves.

"What do we do now, Pein-sama?" Konan asked, while looking at the Rinnegan-wielder.

With "Madara" dead, Pein was now the official leader of the Akatsuki rather than just a figurehead.

"The plan remains the same, we will track down the Jinchuuriki and extract their Tailed Beasts. Though for now, we'll focus on disposing of Hanzo." Pein said.

Even without "Madara", they will still bring peace. In fact, Pein was thankful to those wolves for dealing with "Madara", as he never trusted the man.

Now he didn't have to worry about him betraying them.

*Timeskip-Fourteen Years*

*Konoha*

Fourteen years have passed since the Kyuubi attack and many things have changed.

Upon their return to Konoha, Sarutobi had once again taken up the mantle of Hokage again and his first order was to have Inoichi look into the Masked Man's head and find out everything he could.

The next day Inoichi gave Sarutobi the very shocking truth of who the Masked Man was, Obito Uchiha, someone everyone believed was dead. Even more shocking was the reason why he did it and everything else he's done.

Working with Madara Uchiha, working with the Akatsuki to capture the Jinchuuriki and extract the Tailed Beasts, reforming the Juubi to initiate the Infinite Tsukuyomi, they learned everything Obito planned to do.

And all because he desired to see a fake illusion version of Rin Nohara.

When he learned all of this, Sarutobi had sworn Inoichi to secrecy, given if all this information was leaked, then it could throw the entire world into panic.

In regard to the villagers wanting answers of what happened, the only thing he told the people was the true mastermind behind the attack had been Obito Uchiha. It shocked everyone that Obito Uchiha, someone who was considered a War Hero, was responsible for the Kyuubi attack and death of the Yondaime. It had especially hit Obito's former comrades and classmates, none more than Kakashi Hatake, Obito's former teammate.

Obito's name had even been struck from the Memorial Stone, no one wanting the man who had nearly destroyed their village to be honored in such a way.

Thankfully this gave the villagers a different source of hatred than the Uchiha Clan as a whole, or young Naruto and Mandy, whose Jinchuuriki status was kept hidden. Unfortunately, around six years after the Kyuubi attack, someone had leaked the information of the twins Jinchuuriki status, and Sarutobi had feeling he knew who, but couldn't prove it… yet.

Though once again, most of the villagers still blamed Obito for the attack and not the twins. But there were still the few that did see the twins as the Kyuubi, however these people never did anything to the twins for one very simple reason.

They were all fucking terrified of Mandy Uzumaki.

Even the Hokage was terrified of the girl. There was just something… wrong about her.

Never once has he seen Mandy smile, cry, or act remotely like a normal little girl. She always had a permanent scowl on her face that warded off anyone who tried approaching, it's when she glares at people that makes them run away. Mandy doesn't even do anything, all it takes is one glare and grown adults are sent running with their tails between their legs, it's even worse when she talks to someone.

Hiruzen still had a hard time believing the time he saw Mandy reduce a Hyuga to nothing but tears with just a few choice words. It would have been funny if it hadn't been so terrifying to everyone who witnessed it.

The only person that seemed immune to Mandy's attitude was her brother, Naruto. In fact, Sarutobi had been worried about Naruto developing a darker personality from his sister.

The six Academy students he sent to the intensive care ward at the hospital warranted this worry. Naruto's reason for doing this being they had been insulting his sister.

Between the two of them, Sarutobi was genuinely worried for what they'll be able to when they're older.

*With Naruto and Mandy*

In their home, Naruto and Mandy could be seen sleeping next to each other in their bed. They had both shared a bed as long as they could remember, and neither felt the need to stop anytime soon.

However, it didn't last long when the alarm clock went off, though it was immediately silenced by a fist smashing it to pieces.

"You broke another clock, sis." Naruto stated as he opened his eyes, already knowing what happened.

"They should learn to make quieter clocks." Retorted Mandy, hating having her beauty sleep disturbed.

Throwing the covers off revealing she was wearing only a pink bra and panties, with Naruto only wearing black boxer shorts.

Idly, Naruto's eyes wandered up and down Mandy's figure. Despite being only fourteen, Mandy could be described as an early bloomer, with curves in all the right places, long smooth legs, wide hips, a narrow waist, and High-C Low-D cup breasts.

"Ogle me later, we have to get ready." Mandy said as she felt her brother's eyes on her.

"Well when you do that, how can I not?" Asked Naruto as Mandy started stretching, pushing her chest out and bending over.

Mandy rolled her eyes, though had a small unnoticeable smirk, knowing exactly how her actions effected Naruto. While some might consider it immoral for siblings, twins no less, to have such thoughts and act this way around each other, but Mandy never had the best moral compass to begin with; and thanks to her influence, neither did Naruto.

Like hell she was going to have her brother run around shouting about being Hokage and pulling pranks, and Kami forbid, wearing some hideous orange jumpsuit.

They haven't actually done anything to forward, at most making out and groping in their underwear. Neither of them have decided on what they exactly were yet, but they knew their relationship was more than just siblings.

After taking their showers, separate ones, they got dressed. Mandy's attire looking similar to what she wore in her old life, though instead of pink it was a short black dress with pink bands and straps, with a yellow flower resting between her breasts on the front, a black headband, a weapons holster strapped to her left thigh, and Mary Janes. She looked virtually identical to how she did when she was in her teens, back in her first life; the old differences being that she had whisker marks, like Naruto, and her eyes were now a very, very dark blue rather than pure black.

Naruto's attire consisted of black steel-toed boots, black pants with crimson red trimming, a dark crimson red sleeveless skintight shirt, and a black leather jacket on over it.

"Now who's ogling who?" Naruto asked, smirking when he saw Mandy looking him up and down.

Instead of responding, Mandy grabbed Naruto by his collar and smashed her lips against his, Naruto responding immediately and grabbing her hips.

The twins made out for several moments, Naruto even lowering one of his hands and kneading Mandy's ass. Finally, they pulled apart, and wordlessly, Mandy turned around and left the room while swaying her hips.

"Tease." Naruto muttered before following her out the room.

Walking downstairs, the twins saw that breakfast was already made and at the table, along with the third occupant of their home, who had a newspaper up in front of their face.

"About time you two got up. I thought dat you two were going at it like rabbits." The person said in a deep baritone voice with an oddly fitting Jamaican accent.

The person lowered their paper, revealing not a human person, but a skeleton wearing a full-length black robe with a red interior. Leaning next to the skeleton was a wicked looking scythe blade.

This was Death itself, the Grim Reaper, Naruto and Mandy's best friend/slave.

"Hey Grim." Naruto greeted as they sat at the table.

Mandy didn't give a greeting and simply started eating the food that Grim prepared. She still liked the fact she had her friend/slave back serving her and her brother, though I guess he was also her handler now, given what he told her when he showed up five years ago.

*Flashback*

Mandy sat in the living room reading a book with bowel of nuts next to her. It was just her at the moment, Naruto was out training, leaving her to have some peace and quiet.

However, it was soon interrupted when she looked up and saw a blade stab through the fabric of reality and create a dimensional portal. Mandy raised a brow when she saw Grim walking out from the portal, carrying luggage, which he promptly dropped on the floor, and sat down across from her with a less than happy expression.

"Grim." Mandy stated.

"Mandy." Replied Grim, before they fell into silence.

"Why are you here?" Asked Mandy, having thought Grim would have happily never seen her or Billy again.

"You. Da Shinigami has ordered me to be your handler and make sure you don't destroy da whole multiverse, womon." Grim answered, with Mandy nodding at this, pleased at having the Grim Reaper as her friend/slave once more.

"Where's Billy?" Asked Mandy, having been curious on what happened to her idiot friend after he died.

"He went to Asgard, upsetting Thor and Odin at having ta deal with him again. Somehow, he both caused and prevented Ragnarök, now he's ruling Asgard." Grim answered, with Mandy looking at him completely confused and baffled at his response.

"How?" Mandy asked.

"Don't ask. Even I don't know how it happened." Said Grim, having never figured how Billy managed to both start and prevent Ragnarök, then becoming ruler of Asgard.

Mandy accepted this, feeling that trying to solve it would only give her a migraine.

"Well get started on dinner. Naruto will be home soon, he's my new twin brother. Now get to it." Mandy ordered.

Groaning Grim got up and headed to the kitchen to start dinner.

*End Flashback*

It had come as a shock when Naruto learned that they now had the Grim Reaper as a friend/slave. Though, Mandy and Grim decided to not tell Naruto that he's also her handler, Grim because he had to follow their orders and Mandy because she's long since decided to embrace her new life and leave her old one behind her. But she did tell him who their parents are and about the Kyuubi sealed inside them, passing it off as having asked Grim.

Though while Naruto was darker thanks to Mandy's influence, he was still at least courteous to Grim, which was a breath of fresh air to the skeleton, who was expecting just a male version of Mandy. He also didn't really care about their taboo relationship, he's the Grim Reaper, he doesn't judge, he just reaps the souls and keeps the balance of life and death in order.

Once the twins finished eating, they headed out the door to the Academy, Naruto excited about finally becoming a Ninja. While Mandy knew this was just the first step in her new plan to conquer all of existence.

'And this time, I'll at least have a competent partner to help. A new partner in every sense of the word.' Mandy thought while looking at Naruto.

Yes, this new life will be much better.

So, what did you think, good. Yep that's Naruto's twin sister is the Incarnation of Evil itself, Mandy! Not only that but Mandy has all her memories intact and has new plans to conquer all of existence with Naruto as her partner. And Grim is back to be their friend/slave along with Mandy's handler, but less face it he wouldn't be able to stop Mandy if she wanted to destroy the multiverse. Also the little part at the beginning is basically Mandy intro like in the original show. So, review if you liked go away if you didn't.

Storm out
