After reading some Naruto/Fate Stay Night fanfics where Naruto has EMIYA's powers I decided to do my own with some changes. Naruto x big harem and possible lemons later on.


"Why? Why did they do this? There's two of us and two clans so why did they have her be the heir to both clans and not have us be the heir to one clan each?" An eight-year-old Naruto (canon appearance) said as he sat on his bed crying with a broken heart. Ever since that day when that masked man and the Kyuubi attacked everything went wrong. That day his father no not Father Minato the 4th Hokage defeated the Kyuubi and sealed it away by splitting it in three parts Yin Chakra, Yang Chakra, and Soul sealing the Yin Chakra in his ex-mother Kushina, the Yang Chakra in his ex-twin sister Hitomi, and the Soul in him but only Hitomi was seen as a hero and was praised and loved by practically by everyone while he was seen as the Kyuubi incarnate and was hated and treated like scum by almost everyone in the village and already had to deal with mobs beating him with some trying to kill him but that's not the worst part. No, the worse part was he was ignored by his parents and his ex-sister treated him like scum and calling him a failure. It's not his fault Minato and Kushina as well as Jiraiya never trained him. He asked numerous times and yet every time he asked he gets-

"We need to focus on your sister's training so she can control the Kyuubi's Chakra. You'll get training when you start the Academy."

Why can't they trained them both or at least give him a scroll to learn from or even a damned Shadow Clone? Naruto asked that as well but when he did they got angry and sent him to his room without supper and grounded him. When he was 7 Naruto sneaked into the library a couple times while everyone was sleeping and used some blank scrolls to copy some stuff like the three Chakra control exercises, the Shadow Clone Jutsu and some Jutsu that was derived from it and some Jutsu that was related to it, some sealing techniques like how to make Sealing Scrolls and Explosive Tags, as well as a few Element Ninjutsu about 3 each of the five elements, some Taijutsu styles and a few non-Elemental Ninjutsu (leaving the Rasegan and Minato's Flying Raijin Jutsu alone not wanting to press his luck) and thinking that if they weren't going to trained him till the Academy he'll do it himself. After finding a good hiding place to trained he first started by learning the Shadow Clone Jutsu because once dispersed, the clone's experiences and remaining chakra are transferred back to the user which is really useful when it comes to learning.

After he succeeded learning how to use the Shadow Clone Jutsu he created at least 50 clones and have 35 of them worked on the Chakra control exercises while he practices on Kunai and Shuriken throwing as well as his Taijutsu training with the remaining 15. After a month of doing this and then doing them himself to test himself he had mastered all three Chakra control exercises he moved the clones on to learning how to make Sealing Scrolls which due to his Uzumaki heritage and clones it only took 1 week to mastered making Sealing Scrolls. The clones moved on to making Explosive Tags which was mastered in a week. After that with the help of the clones Naruto mastered the Shadow Clone Explosion, Ninja Art: Shuriken Shadow Clone Jutsu, and learned how to do it with Kunai and Fūma Shuriken, the Transformation Jutsu (mastered to the point where the Transformation is capable of fooling low level Jonin), Teleportation Jutsu, Substitution Jutsu, Escape Jutsu, Paralysis Jutsu, Manipulated Shuriken Technique, and Manipulated Shuriken Wire Binding in 2 weeks and 3 months. After getting his hand on a Chakra Paper and learned that he had a Wind, Fire, and Lightning Affinities.

He then one more time sneak into his family library and copy the information he needed to start training his Affinities which even with the Shadow Clones took 3 months to get them to a good level. He wishes he has a Chakra Blade or 2 so he can use his wind Chakra to increase making the blades far sharper and giving them greater reach. Something to get in the future he supposes. The clones (this time making 100 Clones and having them work the Jutsu with him) then moved on to learn Wind Style: Gale Palm Jutsu, Wind Style: Great Breakthrough Jutsu, Wind Style: Vacuum Bullets Jutsu, Fire Style: Fireball Jutsu, Fire Style: Dragon Flame Jutsu, Fire Style: Phoenix Flower Jutsu, Water Style: Liquid Bullets Jutsu, Water Style: Raging Waves Jutsu, Water Style: Water Dragon Jutsu, Earth Style: Headhunter Jutsu, Earth Style: Earthquake Slam Jutsu, Earth Style: Mud Wall, Lightning Style: False Darkness Jutsu, Lightning Style: Thunderclap Arrow Jutsu, and Lightning Style: Shadow Clone Jutsu. Mastering the Wind, Fire, and Lightning Jutsus was easier but still hard and he had a good understanding of the Taijutsu styles he copied but they didn't feel right for him all before today. Unfortunately, today was the day he was fully betrayed by his parents and Godfather. Instead of making him the heir to one Clan and Hitomi to the other they made her the heiress to both and by doing so according to Clan law they disowned him, and she even signed the Toad summoning contract.

'One thing for sure I can't live here anymore." Naruto said after a while and immediately packs all his stuff into a storage scroll and while everyone was distracted at the party, he left without alerting anyone and went to his training place. When he got there an old man was there. Naruto's pain and sadness turned into red hot angry seeing someone without his permission in his training ground and confronted the old man.

"Hey old man! What are you doing here!? This is my training ground! Get out!" Naruto yelled at him. The old man looked at Naruto when he yelled and smiled. But it wasn't an ordinary smile. No, it was a trolling smile of mischievous. Naruto when he saw that was on high alert knowing something was going to happen but then Naruto started to feel really dizzy and then fell unconscious. The old man went to Naruto.

"Time for some mischief." The old man said still smiling that smile that means major headaches and possible loss of sanity for all involved.

(Inside Naruto's mindscape)

"Ugh what happened?" Naruto asked when he woke up. He then noticed he was in a sewer.

"And why am I in a sewer? Did that old man throwed me in a sewer?! I'll make him pay! Though granted I was rude to him." Naruto said with some anger. He then noticed some pipers leading to somewhere and decided to follow them. After a few minutes of following them, he came a large gate with the Kanji for "Seal" on them.

"So, my jailer has finally decided to appear." A booming voice said.

"Jailer?" Naruto questioned wondering what the voice meant when suddenly it hit him.

"Kyuubi." Naruto said with a small amount of fear. The voice then chuckles.

"That's right. Seems you aren't as stupid as you look." The Kyuubi then reveal itself. Though the Kyuubi isn't as big as it used to be about ¼ its original size and only has 3 tails it was still scary to Naruto.

"Don't worry I won't kill you yet after all thanks to you I been regaining my Chakra a little faster than I usually recover." The Kyuubi said.

"What do you mean? How can you regain your Chakra?" Naruto questioned.

"Simple even though that bastard took my Chakra from me and sealed it into your mother and sister, or should I say ex-mother and ex-sister" here the Kyuubi had a small look of pity for Naruto for a moment while Naruto looked angry at the reminder

"I can create new Chakra for me like any other being can and the Chakra that was taken from me will eventually disappear though not before increasing their Chakra reserves when even they don't used it making their Chakra levels almost reach high Kage level with all training they have and will take in the future." The Kyuubi said angered that it's Chakra was helping that bitch Kushina and her brat.

"I have also been taking some of your Chakra that you haven't been using to help me recover faster but I did have to something in exchange, so I managed to give you a Fire Affinity and used some of the Chakra I had recovered to help increase your reserves as well as temporarily boost your healing as payment." The Kyuubi said.

"While I am a little ticked off on the fact you were stealing Chakra from me, I am grateful for the stuff you given me so thank you very much." Naruto said as he bows to the Kyuubi in thanks.

"Bah don't worry about thanking me since it was in self-interest. After all, if you die, I die though as a Tailed Beast I will eventually reform and I refuse to have a weak jailer." The Kyuubi said secretly a little touched that he thanked it.

"If you refuse to have a weak host how about I help with that?" Said a mysterious male voice.

"Who's there?!" Naruto yelled out. The voice then revealed himself showing that it was the old man from earlier.

"How did you get in here?" The Kyuubi questioned in surprise.

"When you be around as long as I have and been to many different places some of which you think was impossible to exist you tend to pick up some tricks." The old man said.

"Who and what are you and why are you here?" Naruto questioned not trusting the old man.

"I am the Wizard Marshall and the master of the True Magic known as the Kaleidoscope! A dead Apostle! I am Kischur Zelretch Schweinorg! Call me Zelretch and I'm here because I'm bored." He said starting off strong then ending normally.

"Bored? Wait Magic doesn't exist!" Naruto exclaimed.

"Kit I can sense he's telling the truth and I don't feel any Chakra from him, nor does he smell like a human." The Kyuubi said wary of Zelretch.

"That's right. You see due to me being a Dead Apostle I have lived for a long time and seen and did many things. But eventually I have recently gotten bored and thought I needed a project and looked at various worlds and saw a version of your world and gotten interested in it. So, I looked for a version I can do a project on and found this version. I watched you from time to time and admire your dedication despite the neglect and lack of love from your former parents but unfortunately I saw what they did, and I saw what would happen in the future and I decided to act. I am going you Naruto a new power and a new friend. As for you miss Kyuubi I will do something that will allow you some freedom." Zelretch said.

"Really/Really?!" Both Naruto and the Kyuubi said in surprised.

"Wait. YOU"RE A GIRL!?" Naruto yelled out. The Kyuubi sighed.

"Yes, I'm a girl. Got a problem with that?" The Kyuubi asked with a little malice.

"No, I don't. Just a little surprised I guess since I thought you were a male because of your voice." Naruto said.

"Well, I admit my voice does throw everyone off so you can't really be blamed for thinking that. By the way, my name is Kurumi." Kurumi said revealing her name.

"Kurumi." Naruto said trying it out.

"I like it. Though why did you tell me your name?" Naruto asked.

"Because if we're going to be struck together might as well be on good terms. Plus, you are currently my only shot at killing Madara Uchiha." Kurumi said with a lot of venom on the name she said.

"Wait Madara's dead so why do you want to kill him?" Naruto asked confused.

"He controlled me twice. Once against the first Hokage which led to me being sealed into Mito Uzumaki and the night I attacked the Village. While I could be wrong about the second time that man's Chakra felt too much like Madara to be anyone but him." Kurumi said sure of herself.

"If it was Madara or not doesn't matter. That man was responsible for not my pain but the pain and deaths of others. So yeah, I'll take him down." Naruto said without any hesitance.

"So will you be willing to accept my offer." Zelretch said.

"One question. What's the price?" Naruto said wanting to hear what he might have to give up.

"It's nothing much. Just keep me entertained. Though you both will experience some pain from the new power and the new limited freedom, but it should quickly pass in 10 or so minutes. The new friend I will give will mostly cause you some headaches, irritation, and some embarrassment but what he'll give will be more than good." Zelretch said. Naruto and Kurumi both looked at each other and after a couple minutes they nodded and turned to Zelretch.

"We'll do it/We'll do it." They said together.

"Great first thing first Naruto you'll need to take off the seal off the gate." Zelretch said. Naruto then did that, and the gate opens.

"Good. Now brace yourselves." Zelretch said as he held up two cards and throws them at Naruto and Kurumi. The cards glowed and entered them. After a few seconds both started to feel intense pain. The pain was too great, and they passed out.
