Current Time...

Wind blew past Naruto's face and howled in his ears as he fell down the ravine. The young shinobi began to think about how he got into this. He had been training with Jiraiya to prepare for the Chunin Exam's final rounds. The Toad Sage had taught him how to summon Toads … which Naruto admit that he was terrible at. At best, he could summon tadpoles or partial transformed toads. In order to speed up his training and summon the boss toad, Gamabunta, Jiraiya decided to take a gamble and push Naruto off a cliff and into a ravine located in the middle of nowhere. He did this in an attempt to allow Naruto to access the Kyuubi's chakra more easily by forcing Naruto into a situation where he would be forced to access it or die (Jiraiya was quick to realize Naruto was more capable of learning things under pressure). The young shinobi's thoughts began to rush through his head.

"D-damnit! I can't die here! I WON"T die here! There's so much I have to do with my life! Come on, you damn fox, give me your chakra or we're both going to die!"

With that, Naruto bit down on his thumb and let blood cover his entire hand. Gathering up as much chakra as he could, he then went through the appropriate handsigns as one thought went through his mind.

"Well, here goes nothing…"

"Summoning Jutsu!"

[Unknown Dimensions]

Elsewhere...

In a world between worlds, there rested a device. A device that chose seven specific mages, who were to summon a servant, a legendary hero reborn anew. These servants would fight to the death in an event that could only be described as a war. The mages would kill each other or do the cruelest things imaginable. And it was all for this device, which would grant a single wish. No matter what that wish was, it would be granted.

And this device was known as the Holy Grail.

However, it was not the chalice that Jesus Christ and his disciples drank from during the Last Supper. But it was majestic and powerful enough to warrant that name. Unbeknownst to the mages, the grail had become corrupted during the last war, in an act of defiance from one of the servants.

"Summoning Jutsu!"

The conscience inside of the grail grinned to itself as it heard the boy's shout. It no longer had to late for the next Grail War to escape. It had found a way out! The grail quickly searched the world that the boy came from for suitable masters, and gave them each a servant that was originally intended for the Fourth Holy Grail War.

Poor Naruto had no idea that he had just opened a can of worms.

Back with Naruto…

Smoke came out of Naruto's hands, just like his other failed summonings. What differ from the rest was that it had a faint red glow to it. The young shinobi suddenly felt something catch him. He suddenly looked behind him and widened his eyes in surprise.

The person who caught him was a girl, who appeared to be in her late teens, and had a presence of nobility with her. She wore a blue dress with silver armor covering it. She had golden blonde hair kept up in a bun with a few strands framing her face, and an ahoge that appeared on the top of her head. Lastly, she had emerald green eyes that were cold and professional.

Naruto could only think of one thing as he looked upon his rescuer.

"She's real pretty."

"Hang on," the girl said as the two headed towards one of the ravine's walls. She suddenly dug her heels into the wall, and they began to gradually slow down. The girl then jumped upwards to the next wall before kicking off it. This process repeated for some time until they reached the top of the ravine, where the girl put Naruto down in front of a shocked Jiraiya.

While this was happening, six other servants were being summoned.

[Akatsuki Hideout]

Meanwhile...

Tobi's one visible eye narrowed as he looked at the strange seal array that suddenly appeared on the floor. He didn't know what to make of this. He doubt that the late Minato Namikaze, or even the Uzumaki clan could figure out what kind of seal this was. The seal began to glow red, and the present Akatsuki members (with the exception of Itachi and Kisame, who were not there) were taken off guard by this. Pein, Konan, and Tobi remained calm as a figure suddenly emerged from the seal and stepped forward.

The figure was a fairly tall man who appeared to be in his twenties. He had golden blonde hair that stood up like a blazing flame, and had crimson eyes that were colored like blood. Judging by Konan's reaction, he was fairly handsome; with an elegant face that looked like the Gods themselves carved it. He wore golden armor, completed with golden earrings and a red cape, which started at his waist and ended at his ankles. The man stood there with his arms crossed, giving off an air of arrogance.

"What the hell just happened? Who is this man?" Tobi thought to himself as he looked down at his right hand. On it was a marking. It took the form of a bird with two crescent moons, one larger than the other, on top of it.

[Unknown Location, Land of Fire]

Meanwhile...

Sasuke tensed as the seal array glowed in front of him. He was training with Kakashi for the finals of the Chunin Exams and was taking a break when the seal appeared. The seal flashed red, and a person suddenly appeared before him. It was a young man with an athletic build similar to a runner's. The man had quirky black hair that was lazily combed back, with a lock of hair that framed his forehead. He wore a dark teal colored outfit that was sleeveless on the right side while the left side had a sleeve that ended at his bicep. The outfit had a few pieces of armor on it, including a spaulder on his left shoulder. In his hands were two spears, both covered in purple bandages. The one in his left hand was around a meter and a half long and had a yellow spearhead. The one in his right was two meters long and had a red spearhead. However, the most noticeable thing about the man was a beauty mark located under his right eye.

The Uchiha clansman stepped back as the young man suddenly kneeled in front of him. Sasuke then felt a burning sensation on his hand and looked down at it. On the back of his right hand was some sort of crimson seal. It resembled a lance with a pair of wings and two flames on the side of it.

"What is this?" Sasuke wondered to himself.

[Konoha Hospital, Konohagakure, Land of Fire]

Meanwhile...

Hinata shook in fear as a man emerged from the seal that appeared on the floor of her room. The man was a giant, standing at least seven feet tall. He possessed a very muscular and chiseled figure, and across his body were various scars, which were signs of previous battles. The man's hair and beard color were scarlet, and he wore bronze armor of some sort along with cuffs and greaves. Draped upon his shoulders a thick red mantle that had fringes on the collar and edge. The mantel looked luxurious, like a curtain from the stage of a theater. The man possessed a presence that gave the impression that he commanded thousands of soldiers and led them into many battles.

"W-what's going on?" Hinata thought to herself as the man looked over her. The Hyuga heiress suddenly grimaced as she felt her hand burn. She looked down at it, and on it was a seal. It resembled a stylized broadsword pointing up with two wings on the side of it.

[Somewhere in the Land of Fire]

Meanwhile...

Itachi's eyes widened as a figure suddenly came out of the ground. The figure appeared to be a knight wearing pitch black armor. Parts of the armor looked jagged. A purplish-black smoke came out from the joints and opening of the armor, obscuring its features. The visor of the helmet gave off a hellish red glow. The knight stared at Itachi for a bit before letting out a low, guttural growl.

"Who is this? Hey, you know this guy, Itachi?" Kisame asked as he gripped the hilt of Samehada.

"I don't," Itachi answered as he looked down at the back of his hand. It now had a crimson seal on it, resembling three jagged blades going off in different directions.

[Kazekage's Office, Sunagakure, Land of Wind]

Meanwhile...

Orochimaru smirked to himself as he sat in the Kazekage's office. He had killed the fool and taken his place, and no one had suspected a thing. So far, everything had been going to plan…

…except for one detail.

A strange seal array had appeared in the room, and a person had emerged from it. It was a man who stood at six foot four. He had wild grey hair , bulging eyes that looked like they belonged on a fish, and his skin had a pale color to it. He wore a grey black robe with strange designs on it, along with a cloak. In his claw-like hands was a book that looked like It was made out of human flesh. On its cover was a face that seemed to be screaming in agony.

Orochimaru looked at the man in front of him before eyeing his hand. On it was a seal that had a sickle like design to it. The smirk on the Snake Sannin's face grew as he thought to himself.

"Kukuku, this is certainly an interesting development."

[ROOT Headquarters, Konohagakure, Land of Fire]

Meanwhile...

Danzo Shimura stared down at the person in front of him. He appeared via a strange seal that suddenly appeared in the middle of the room. It was a man who was lean yet had an athletic build to him. He had dark skin, lacked a shirt, and his pants looked like black rags. On his arms were what appeared to be brown metal armbands, and his belt were a pair of curved knives. The most notable thing about him was a bone white skull mask that covered his face.

The warhawk's expression remained neutral as he looked down at his good hand. A crimson seal appeared on it, resembling zig-zags that intercepted each other, but were somehow still separate.

"This is most unexpected? What does this mean?" Danzo thought to himself.

[Unkown Location, Konohagakure, Land of Fire]

Back With Naruto...

"Naruto, are you alright? And who is this girl?" a shocked Jiraiya asked as he stared at the young woman in front of him.

"I-I don't know," Naruto said as he gathered his bearings. He then suddenly felt a burning sensation on his hand, like if someone was carving into it with a red hot poker. He flinched and then look down at his hand. A marking appeared on his hand. It looked like a four point star, with the point at the bottom being much larger than the other three points. It reminded Naruto of a sword.

The girl eyed the seal on his hand. She then looked into his eyes and spoke in a stoic tone.

"Upon your summons, I have appeared. Now, I must ask of you… are you my master?"

The seven servant classes of Saber, Archer, Lancer, Rider, Berserker, Caster, and Assassin had been summon to the Elemental Nations. The land was about to experience its first Holy Grail War.

Next Time - The Worst Possible Time: What is the Holy Grail War?

A/N: Welcome to the first chapter of Fate/Zero Shinobi! First off, I have to give credit to the Infamous Man for coming up with this idea. Unfortunately, he said that he had left the Naruto genre, so I decided to ask him if I could write this fic, and he gave me his permission. I suggest that you check out his own excellent Fate/Zero crossover fic, Just an Unorthodox Thief, along with his other stories. Now you may have noticed that I've changed up a few of the master/servant pairings. I mainly did this for my own preferences. I'll also try to update this story as frequently as I can, since I have college work to do along with updating my other stories. Now don't forget to leave a review.
