Sorry for the late update. I honestly wasn't expecting the amount of attention this fic got despite being less than 4000 words long, so I have a few things to say.

First of all, I literally wrote this piece of fanfiction on a whim. I did almost no planning, the idea appeared in my mind and I acted on it, simple as that. The reason this fic even exists is because of the Halloween gacha on F/GO. With that being said, I have no intention of letting this fic die, especially not after getting all these reviews and follows.

Secondly, after I uploaded the second chapter of this story, I immediately opened F/GO and attempted to roll for Tamamo. I managed to pull her after using 60 free quartz (which is all I had, to be honest), proving that having loyal readers backing up this catalyst of a story beats the desire sensor and RNG. Thanks to you all for beating the gacha for me. I promptly forgot about this story for a while afterwards because I was too busy ascending my shiny new Tamamo.

On a side note, if you want to add me in F/GO you can shoot me a PM on here and I'll send you my friend code as long as I have space (I play the NA version).

Thirdly, there won't be a super OP Naruto running around just because he has magic circuits, and he won't be learning any crazy magecraft or anything like that. Those are solely reserved for channeling Tamamo's powers (healing, transformations, etc.) because she is a Servant who runs off of magical energy. I've already committed to having her survive on natural energy and chakra, too late to change that now. The Kyubii would have pumped his chakra through Naruto's chakra pathways to unleash his powers, so similarly, Tamamo would have to channel her magical energy through magic circuits to provide her power.

I had to take artistic license to bend the rules because Tamamo would simply fade from existence due to running out of energy. I mean, if you can stick a magical sheath into a boy and literally turn his existence into a sword, then surely having a Caster bonded to you since birth would cause a few changes too. So don't get too mad at me, this is a fanfiction anyways and that's part of the fun, right?

Lastly, there won't be Naruto x Tamamo. Yes, it would be very easy to write it that way, her personality certainly makes that task simple. But then I thought, has there ever been a fanfic portraying her as a maternal figure? I like to think of it as 'diving into uncharted waters'. I've already accepted the fact that it's impossible to make all of my readers happy ('That's hell you're walking into." -A certain red Archer) but I still like to try wild ideas anyways. Tamamo is labeled as an anti-hero with a Neutral Evil alignment, so having a kid like Naruto around would be good for her anyways, I think. After all, her legend doesn't exactly have a happy ending.

You won't be seeing such a long A/N from me for a long time, probably, so enjoy the story now. As usual, thank you for your continued support.


Naruto woke up, finding himself laying in a dark sewer. Ignoring the water on the floor, he got up and walked forward, with a strange nagging feeling in the back of his mind that this was supposed to be a familiar place.

He kept walking until he saw a massive cage in the distance. He squinted his eyes as he noticed something, no, there was someone inside that cage. Determined to find out what was going on, he ran ahead.

Naruto slowed down as he reached the cage, panting hard as he tried to catch his breath. He looked up towards the cage to see a brown-eyed woman staring back at him with an expression of shock. She had pink hair, styled into two pigtails and secured with a large blue ribbon. She wore a rather revealing blue kimono-looking outfit, secured with a black sash adorned with fox tail patterns.

Perhaps the most striking features on her were the fox ears on her head and the very large fox tail poking out from behind her.

"You...you...mikon~!"

The strange fox woman ran forward with her arms wide open, only to crash into the bars of the seal face first as they moved closer together to keep her trapped inside.

"Ah, that hurt..."

The impact made her fall right on her butt, and she winced as she rubbed her sore face.

"W-where am I? And what are you doing here?" Naruto asked.

"Well, this is supposed to be your mind." she replied as Naruto jaw dropped. "And as for why I'm here, I was sealed into you since you were born, I think. Although I can't figure out why they would summon me just to do such a thing." she muttered the last part quietly to herself.

"What?! Why is my mind a sewer?" Naruto yelled. Evidently that was bit too much for a three year old boy to handle.

"Now, now. I'm sure we can get that sorted out in the future. Now come here, Naruto-chan!"

She pulled the boy through the seal and gave him a big hug.

"Mikon~! What a cute Master I have! I was expecting a handsome Master to appear and be my husband, but this is fine too!"

"Um...what's a master?" Naruto asked innocently.

"Err... I'll tell you about it when you're older." she replied with shifty eyes. "You're a bit young for this."

"Okay!" Naruto smiled as she wrapped her fluffy tail around his small body.

"Ah, this innocence of children..." she mumbled to herself, wondering why a child would have a Heroic Spirit bound to him, much less an anti-hero like herself.

"Oh no, what about that girl?" Naruto's eyes snapped wide open as the sudden realization struck him.

"Oh, that's right! Here."

Naruto watched as the fox woman held her hands out and sent a pulse of green energy through the seal.

"You should be fine for now, but your body will probably be hurting all over, especially your legs. Go find a doctor if you can, but even if you don't, I'll fix you up regardless so don't worry."

"Cool! Thanks...um... what's your name?" Naruto rubbed the back of his head sheepishly.

Her face briefly darkened for moment as thoughts began running through her head. Should she tell him her name? She could easily just call herself Caster and be done with it, or lie and make up some random name. After all, the people here looked Japanese, so it wouldn't be hard.

But looking at that innocent three-year old child, she couldn't bring herself to lie. Besides, if there was actually a Grail War going on, this child would have died a very long time ago. And Grail Wars certainly didn't go on for years.

"My name is Tamamo-no-Mae. But Tamamo is fine." Tamamo replied cheerfully.

"Thanks, Tamamo!" Naruto hugged her legs before vanishing from the mindscape.

Shaking her head, she sat down and focused on healing her Master once more. The magic circuits that lined the walls of the mindscape lit up in a familiar teal glow.

Narrowing her eyes, she stopped channeling magical energy. Almost immediately, the circuits died down into a gray color as they went inactive.

"Hmm."

Tamamo would have some experimenting to do later.


Hinata watched as the ninja knocked the blond boy to the ground when he tried to attack him with nothing but his fists. She tried to scream when the boy got up again, only to receive a punch to the head for his efforts. She had resigned herself to her fate as the ninja turned around to pick her up again.

By some miracle, it didn't happen.

She watched in amazement as a massive gust suddenly blew the ninja to the ground, the blond boy getting up once more and appeared to be morphing before her very eyes. His simple T-shirt and shorts turned into a strange blue robe; his blue eyes became a golden shade of brown. His blond hair lengthened and reached down to his shoulders, styled into a ponytail and secured by a large blue ribbon. Most noticeably, fox ears had sprouted from the top of his head, with a matching fox tail to go with it. All in all, he looked a bit feminine afterwards.

She thought it was the most magical thing she had ever seen.

She watched as the ninja threw a kunai at the boy, only to be stopped by some sort of strange mirror. She cheered as the boy moved inhumanly fast, forcing the man down and freezing his legs to the ground. She stared in awe as the man was brought down by a triple ball-buster combo of kicks, complete with a dramatic ending pose and inexplicable explosion in the background, the sight burned into her very impressionable three year old mind.

Then the boy had tore off her bindings, asked her if she was okay, and promptly passed out. His fox ears and tail, mirror, and clothing all dissolved into golden motes of light, leaving behind an ordinary blond boy wearing a T-shirt and shorts. Which now brings us back to the present.

Understandably, Hinata proceeded to freak out. She couldn't just leave the boy here and run back into the village, not after what he had done for her. On the other hand, staying next to the fallen ninja was potentially dangerous, since he could wake up at any time. She quickly turned the boy over so he was laying on his back.

Hinata gasped as the boy's entire body was red. His body felt unnaturally hot, and his limbs were all badly bruised, especially his legs. Evidently, the ability to move at such ridiculous speeds did not come without a cost.

Deciding that getting away from the ninja was the right thing to do, she slowly moved the boy's body until they were both behind a tree a fair distance away. Then, all she could do was wait. She was surprised to see that some of the bruises had already disappeared, and the redness on his body was beginning to fade.

Idly, she began poking at the whisker marks on the boy's face. She gave a soft "Eep!" as the boy began to stir. Blue eyes met lavender eyes as he awoke.

"Are you okay?" the boy asked as he slowly sat up.

"I am, b-but you're h-hurt." Hinata replied.

Give me a few moments, your legs should be fit for walking soon.

"What?" the boy asked out loud.

"I-is something wrong?" Hinata asked.

We can talk now! I can see what you see too, Naruto-chan. Don't answer me out loud, or else people might think you're crazy.

Hehe, sorry. This is just kind of weird. Naruto replied.

"I'm fine. Let's go, um, what's your name?"

"A-ano, m-my name is H-Hyuuga Hinata." Hinata replied while poking her fingers together.

"I'm Uzumaki Naruto! Let's get out of here now, Hinata-chan!"

Naruto grabbed Hinata's hand, eliciting a small blush from the girl as they ran in the direction of the village. As they passed by the ninja on the ground, Tamamo recommended that Naruto should kick the man between the legs again to made sure that he stayed down. The boy obliged, landing a solid kick and making the man squeal again before he fell back down. Surprisingly, Hinata walked up to the man and stomped him in the balls, making Naruto wince and made Tamamo wonder if she had inadvertently been a bad influence on the girl.

After a few more minutes, Naruto had healed enough to run at full speed, and they quickly ran towards some familiar looking people that Hinata recognized.

"Hinata-sama!" A few Branch family members saw the two children running towards them, and quickly made sure that they were alright. One of them ran off to get the clan head and the Hokage.

Soon enough, Hiashi and his wife Hitomi arrived, with the Hokage right behind them.

"Hinata!" Hitomi quickly ran towards her daughter. "Are you hurt?"

"I-I'm fine, but Naruto-kun..."

"Old man!" Naruto grinned at old man Sarutobi.

The Hokage was surprised that Naruto was involved. "Naruto? What are you doing here?"

Naruto was catching his breath as he replied. "Saved Hinata-chan...from...evil man..."

"And where might this evil man be now?" the Hokage asked.

The two children pointed in the direction that they came from. The Hokage motioned with his hand, and several ANBU instantly appeared.

"You know what to do. Secure the kidnapper and take him to Ibiki."

They all saluted and quickly left to do their job.

The Hokage whispered something to Hiashi and his wife, and they all nodded.

"We think you should both get some rest now. I'll drop by tomorrow and you can both tell me your story when you're rested, okay?" the Hokage asked kindly.

The children nodded, and Hitomi took her daughter's hand and led them back towards their clan compound.

"A-ano...is Naruto-kun going to stay with us?" Hinata asked.

"Of course, dear. The clan owes him now. He'll be our little guest of honor." Hitomi smiled, noticing that they hadn't let go of each other's hand since they arrived.

Good job, Naruto-chan! Now you have a whole clan that owes you! Tamamo cheered while Naruto just grinned.


Once they arrived, Hitomi proceeded to give the two children a much-needed bath, before dressing them up in some nice pajamas. By that time, most of Naruto's bruises were gone, and he would be perfectly fine in the morning.

She wondered where she would let Naruto sleep, before deciding that she would just have him sleep next to Hinata. She couldn't wait to see her husband's face when he saw them laying together!

Tucking the two into their bed, Hitomi kissed her daughter on her forehead and bowed to Naruto.

"Thank you very much for saving my daughter, Naruto. If there's anything I can do for you, just let me know."

"Hehe, it was nothing." Naruto replied while scratching the back of his head. In reality, he didn't actually remember much of what he did, but he was sure that Hinata and Tamamo would fill him in later.

"What a modest boy you are. I'll see you both in the morning, then." Hitomi turned off the lights before slipping out of the room quietly, making sure that the Hyuuga guards were on high alert as they patrolled the vicinity.

"G-good night, Naruto-kun." Hinata clutched her teddy bear to her body and stuck her thumb in her mouth before drifting off to sleep.

"Good night, Hinata-chan." Naruto replied as he yawned.

If you need me, just call out to me and I'll be here. I'll be filling up my magical reserves while you sleep.

Wow, you know magic? Cool!

Yes, but that'll be our little secret, okay? I don't want you to run around telling people.

Okay! I'll never tell anyone!

Very good, now get to sleep, okay?

Naruto just yawned as he leaned back into his pillow.


Naruto woke up in the middle of the night to hear a soft sobbing sound coming from the girl next to him.

Tamamo, are you there?

Hmm? What is it, Naruto-chan?

Hinata-chan is crying. Naruto frowned and turned his head towards Hinata so Tamamo could get a clear view of what he was seeing.

I think she's having a nightmare. Maybe you should wake her up.

Naruto turned her over and began poking at her cheeks until she woke up.

"What's wrong, Hinata-chan?" Naruto whispered.

"I-I was having a dream about t-the bad man..." Hinata poked her fingers together.

"Don't worry, I'll protect you, dattebayo! Then when we get stronger we'll go beat up all the bad people!"

"O-okay..." Hinata lay back down on the bed as Tamamo thought about how inadvertently romantic that was, even for a three year old.

Here, try covering her with this.

As the two settled down to go back to sleep again, Tamamo channeled a bit of mana to materialize a large fox tail from Naruto's body. She made the tail wrap around the both of them. Hinata gave off a small "Eep!" as the large fluffy tail suddenly surrounded her, but it was soft and warm, and soon the two of them snuggled into each other as they nodded off into dreamland.


Tamamo was sitting inside her seal, drawing in natural energy to replenish her magical reserves that were spent on healing Naruto earlier. Now was the best time to do so, since drawing in energy while he was mostly unmoving made the job much easier, and the seal had loosened ever so slightly after the earlier incident, letting her draw in energy more rapidly and allowed her to communicate with her young Master through a mental link.

So you could imagine her surprise when not one, but two children suddenly appeared in the mindscape.

Naruto woke up first, finding himself laying down in front of the cage with a very surprised Tamamo looking back at him. Next to him was Hinata, who was beginning to stir.

"Ano, w-where are we?" she asked as she looked at Naruto, then turned to see a strange fox woman standing behind bars.

"Woah! What are you doing inside my mind, Hinata-chan?"

"W-what?" Hinata was very confused by what was happening.

"It's true." Tamamo spoke up. "Somehow, you've linked your mind to his."

"W-who are you?" Hinata asked.

"Oh, silly me. I forgot to introduce myself. My name is Tamamo-no-Mae, but you can just call me Tamamo. I've been sealed into Naruto since he was born. I'm not sure why, but that's how it is."

"I-I'm Hyuuga Hinata." Hinata introduced herself with a bow.

"What a polite child. Don't worry, we're all friends here." Tamamo smiled at the small girl.

"Yeah, she's really nice. She helped me save you earlier too!"

Naruto walked through the bars, and Hinata followed after a brief moment of hesitation.

"S-so the f-fox ears a-and tail are yours?" Hinata asked.

"That's right. Naruto-chan wanted to save you so bad, so I used my magic to give him the strength to fight the man off. It really hurt his body, though, so I won't be doing that again anytime soon."

"T-thank you for saving me!" Hinata bowed again.

"It was no problem, Hinata-chan." Naruto grinned.

"Can you promise not to tell anyone about me, Hinata-chan? I'm doing this for Naruto-chan's safety and if people find out that magic is real, then bad people might try to take him away, okay?" Tamamo asked.

"I-I promise! I don't want anyone to take Naruto-kun away!" Hinata looked absolutely horrified at the possibility.

"Very good!" Tamamo pat the girl on the head. "Now, I know that those adults will probably ask questions tomorrow. You can tell them what you saw during the incident, but pretend this conversation never happened, okay? If anyone asks, we never met."

The two children just nodded.

"Now, you've both had a long day." Tamamo had the both of them sit on her lap and wrapped her tail around them. "Get some rest, okay? I'll see you both tomorrow."

Immediately the two children began to doze off while Tamamo just smiled.


The next morning...

Hitomi quietly slid the door open as she peeked inside to check on the children. She looked on in shock before giving a squeal of delight as she saw the two children cuddling together, with a large fox tail wrapped around the two. She immediately ran off to get her husband, and maybe grab a camera too while she was at it.

Along the way, she ran past Hiashi's twin brother, Hizashi.

"Hitomi-sama, is something wrong? I see that you are in a rush."

The woman ignored him as she muttered something about Hinata and a camera. Deciding to see for himself, he walked over to Hinata's room and looked inside, to find the Hyuuga heiress snuggling up to Naruto, who wrapped a fluffy fox tail around them both.

A female branch family member saw Hizashi staring into Hinata's room and decided to walk over to see what was going on. Like Hitomi before her, she also squealed at the cute scene.

"Go bring me a camera, please." Hizashi asked.

"Of course, Hizashi-sama." the woman replied as she quickly ran off to grab a camera.

At around the same time, the Hokage decided to pay a visit to the Hyuuga compound.

"Greetings, Hokage-sama. What can we do for you?" one of the guards asked.

"Is Hiashi-sama available right now?" the Hokage asked.

"I believe that Hiashi-sama is busy with some work related to yesterday's incident. Shall I fetch him for you, Hokage-sama?"

"No, there is no rush. If you would be so kind as to bring me to the children, I would like to see how they are doing."

"Of course, Hokage-sama. Please follow me."

The Hokage followed as the guard led the way towards Hinata's room, only to see a large group of clan members crowding outside for some reason.

"Is something going on here?" the Hokage asked as everyone made room for him to look through the door.

After about five seconds of staring, the Hokage stuck out his hand.

"Camera, please."

"Here you go, Hokage-sama." Hizashi put a camera into the Hogake's hand, which he immediately used to start snapping photos.

By the time Hitomi returned with her husband in tow, practically the whole clan was gathered in that one hallway, with several members holding cameras. The ones that couldn't see into Hinata's room had their Byakugan active to look through the walls.

Hiashi was surprised to see the clan elders there as well. Hell, even the Hokage himself was there. He quietly slipped through the crowd and looked inside to see what the commotion was all about. He only had one word to say.

"Cute."

They all agreed on one thing that day, even if they didn't know it, but they knew that the blond-haired boy was no demon.
