(A/N: Yes, it's ANOTHER new fic. Please refrain from killing me.

I'll spare you my mad demented ravings this time, and just let the fic introduce itself, but frankly, if you can't guess from the disclaimer what it is about, then I can't help you. :p

That said, on with the prologue!)

DISCLAIMER:

Naruto and all its characters are property of Kishimoto Masashi, and I don't claim ownership of them, though I sure as hell would LIKE to, so I could save them from the horrific raping Bakamoto is inflicting upon them. La Blue Girl is property of whoever created it (hell if I remember their name :p ), so not mine either. Any OCs that may appear are my own property.

Prologue: Random Chance or Fate?

Konohagakure, Hokage Monument's Top

"Heh heh heh! This will be my greatest prank yet!"

Thirteen-year-old Uzumaki Naruto couldn't help but giggle in a decidedly disturbing fashion as he secured himself to the complex system of ropes and pulleys he'd set up on the Hokage monument that watched over Konohagakure. He was sure that his latest stunt would get plenty of attention.

After all, how many shinobi would have the guts to deface the Hokage's monument in broad daylight?

As he inspected the ropes to ensure they were securely tied down (it wouldn't do for the future Hokage to become a smear on the ground), he stepped closer to a large crack nestled in between the faces of the First and Second Hokage. Just then, a flash of light caught his eye, causing him to stop and crane his neck in an attempt to identify its source.

"Huh? What is that...?" the blond boy muttered, his curiosity piqued. His elaborate prank temporarily forgotten, he drew closer to the edge and secured himself to a nearby rope, then cautiously peeked between the stone faces, squinting to see in the darkness of the crevasse.

As he moved about, sunlight hit the opening, and once again a small flash of something metallic was seen. After a lot of straining and peeking, Naruto finally determined what it was.

Stairs.

Excited by the prospect of having found something secret, the energetic young boy quickly dismantled the rope system he'd made to paint the monument, and swiftly reattached them in a position that would allow him to lower himself in the crack. After cautiously peering down towards the village to ensure no one was looking towards him - one of the few times in his life when he really didn't want people to spot him while he was up to something - he began to climb down towards the opening.

After a few tense seconds during which he lost his footing and nearly squashed himself against the Second Hokage's stone ear, he managed to set his feet inside the mysterious crevasse. To his relief, nothing collapsed under him - had there been loose floor under his feet, he'd have been in a really hairy situation.

After he freed himself of the security harness he'd used and secured it to a wall, Naruto began to eagerly explore this new, exciting place he found. His excitement was considerably dimmed as he came upon dead end after dead end, the only notable things in the stone monument's bowels being a few half-burnt torches which he luckily managed to light with his limited knowledge of basic Fire jutsu.

Muttering about letdowns and pointless waste of time, Naruto descended yet another flight of stairs, noticing the air in that section of the monument felt very dry and that dust was everywhere, as if no one had set foot inside the place in, oh... decades, perhaps?

Pushing on, he reached a corner, and upon rounding it, his grin returned. A door!

As he approached the door, he noticed that it looked a lot older than anything he'd ever seen in Konoha. The massive wooden slab looked positively ancient, even to an untrained eye like his own, and Naruto began to suspect that whatever he had stumbled upon, it was something nobody in Konoha knew about. His suspicion was strengthened when he noticed faded inscriptions in what was most definitely NOT Elemental Countries language, although he obviously was unable to read it.

In an unusual display of intelligence, Naruto figured that the cave he'd stumbled upon had to have been revealed during the recent earthquake the village experienced less than a week before, as otherwise there'd have been water everywhere from the recent, abundant rainfalls Konoha had experienced.

Excited at the thought of what may lie behind the sealed door, Naruto began to frantically look it over, in an attempt to figure out how to open it. He soon began to feel irked, as there was no keyhole or anything that he could see. Grumbling about stupid doors and even more stupid designers who forgot keyholes, he kicked it in frustration.

The door opened.

For a few minutes, Naruto stared dumbly at the now open door, incredulous at the notion that it would just be left open after whoever made it went to such length to hide it from the eyes of others. Then he pointed at the door, an angry expression on his face.

"What the hell?" he shouted at no one in particular. "What's the point of making a huge-ass door that looks like it weighs a ton and hide it under a mountain of rock if you don't lock it? Dumbass!"

Feeling stupid for having wasted time in looking for a lock that wasn't here, the blond pushed the door completely open and stepped in the chamber beyond.

The room he was in was by far the largest he had come across so far, almost twice as big as his apartment. Unlike the rest of the tunnels, this one had finely sculpted carvings etched in the walls, and several stone pillars, equally well sculpted, could be seen scattered across it.

In the room's center was an altar, and that was what attracted Naruto's attention... for on top of the altar, resting untouched as if waiting for him, lay an ancient-looking scroll much like the ones he'd seen stashed in the Hokage's tower - scrolls where the most powerful and dangerous Konoha techniques were kept.

Without paying attention to the carvings on the walls, Naruto happily skipped towards the scroll, certain it contained a bad-ass new jutsu that was just waiting for him to use it.

Had he taken a closer look to the carvings, he may have doubted the wisdom of even touching the scroll, much less reading it... as most of said carvings depicted people using it - and monsters ranging from relatively humanoid-looking (and sometimes even attractive) to abominations straight out of horrific nightmares coming to answer its call and prey on its wielder's enemies. And what they did to their prey was disturbing. Very disturbing indeed.

Then again... Naruto was never known for his wisdom. And so, he walked over to the scroll, took it and opened it, finding it, surprisingly, written in a language similar enough to the one he was familiar with that he could understand it.

And across the Elemental Countries, many of those who would come in contact with Naruto shuddered, as if Fate had just brushed them.

Several hours later, Naruto shouted in frustration as yet another strangely-shaped slime-thing disappeared in a puff of smoke.

The scroll had turned out to be a Summoning contract of some kind, and while Naruto was unable to read most of it, the part where the scroll depicted how it would enable the one who'd sign it to 'invoke a creature of great power and skill which would bring swift and certain defeat to any enemy' was more than enough to make him rapidly sign it, using his own blood the way he remembered Iruka-sensei explaining how such a scroll was to be signed.

Since that moment, he'd been practicing non-stop to summon whatever it was that the scroll would call, unmindful of the potential danger that such a creature could pose without an enemy to unleash it against. However, all he got was unfortunately (or fortunately, depending on how one looked at it) strangely-shaped slimes that almost but not quite reminded Naruto of mushrooms... or his private parts, come to think of it.

The continuous failures (as he viewed them, not considering the slimes may have been the lowest level of whatever the scroll could call) had slowly but surely fired up his temper, and it had finally reached its boiling point as he kicked a nearby pebble and shot a dirty look at the scroll.

"Ok, that's it!" he shouted in anger. "If my next try summons another stupid slime, I'm burning this stupid scroll and going home! I'm tired and wasting time here when I could play pranks or eat ramen..."

As the blond boy once again performed the required handseals, he couldn't help but think of all the delicious bowls of ramen he could have eaten in the time he'd spent trying to summon whatever the scroll summoned. His temper flaring, he slammed the palm of his left hand down on the now-bloody floor (due to the repeated attempts at calling he made), and let anger take him over just as he shouted - "Kuchiyose no Jutsu!".

He immediately felt something was different. As soon as he'd completed the jutsu, a burning sensation from deep inside his navel spread through his left arm and to his left hand's fingertips. Then, a violent burst of chakra threw him backwards, as a loud explosion was followed by a large cloud of the typical smoke that indicated a summoning being performed. Immediately afterwards, a strong spiritual pressure spread across the room. Had someone more experienced than Naruto been there, they would have realized that whatever he had managed to summon was extremely powerful. As it was, Naruto merely felt as if he was suddenly a lot heavier than usual, and while puzzled, paid it no heed.

Then again, had it been anyone other than Naruto, they would probably not have survived the next few minutes.

As the whiskered boy slowly got up off the floor he'd been thrown on, he raised his eyes - and saw the figure who now stood before him.

The humanoid being he had summoned was imposing, to say the least - he towered over Naruto with ease, being at least nine feet tall and extremely muscular, and the blue hair on top of his head brushed against the cave's ceiling. His blue skin made it obvious he wasn't human, an impression reinforced by the menacing-looking horn-like protrusions from his neck and hips. The red eyes and fang-like teeth just drove the point further home - the being, while clearly male and human-like, was far from a human being. A fur loincloth was the only apparent article of 'clothing' the creature wore, if one overlooked the pendant around his neck and the protectors around his wrists.

The creature looked around the room before his gaze fixated on Naruto, who'd unsteadily wobbled to his feet. As the blond regarded him with awe, he addressed him in a booming voice that made the boy suddenly consider if what he'd done was a good idea at all.

"Where am I? And who are you?" he asked, causing Naruto to take a step back instinctively. "How dares a whelp like you summon the great Seikima, King of the Shikima and a lord of Makai?"

Naruto froze at those words. While he'd slept through most classes, he knew what Makai was. It was where demons lived... most of them very unpleasant to deal with.

...and he'd summoned a lord of the Makai? Suddenly, Naruto felt that he'd made the biggest mistake of his life... which might not last much longer, given the situation.

As the blond frantically thought about a way to defuse the situation, the Shikima king sniffed the air, his eyes narrowing as he regarded the boy before him.

"You..." he intoned, catching Naruto's attention again. "You smell of demon. Are you also a denizen of Makai? It feels familiar..."

Naruto blinked, then shook his head vehemently. "What? No! I'm a human!"

Seikima regarded him with a raised eyebrow, trying to place the smell of youkai he felt coming from the boy, then noticed an unusual aura around Naruto's navel and nodded in sudden understanding.

"Ah, I see. You are one of them. In that case, human whelp, I will forgive your insolence in summoning me without permission. Now, where is the master who helped you? I would have... words... with him."

"Master...? Huh, I summoned you myself!" Naruto replied in confusion. Seikima blinked.

"Alone...? Surely you jest," he replied skeptically, then seemed to reconsider, "Then again, given your nature... It may just be possible. Hmm... very interesting," he added, eyeing the blond with a speculative gaze. Naruto shifted nervously under the Shikima's red eyes, somehow understanding that his continued good health depended on making a good impression on the being.

"Hmm..." Seikima resumed after studying Naruto. "You look a little... weak..."

That comment set Naruto off. Demon or no demon, he hated being called weak. Pointing a finger at the Shikima king, he started angrily shouting, heedless of the huge difference in power between them.

"What! Weak! I'm not weak, you big blue... whatever!" he retorted angrily. "I'm Uzumaki Naruto, and I'm going to be the most bad-ass ninja in Konoha, and one day I'll be Hokage and rule this place! And then everyone, even you, will have to respect me! I'll be the strongest ninja ever! Believe it!"

Seikima blinked at the sudden rant Naruto had launched himself into and the sudden lack of fear and respect he displayed, then started chuckling. Before long, the chuckle had developed into full-blown laughter, and Seikima was straining to hold the tears in, his mirth making the boy before him even angrier.

"Ha-hahahahahahahaha! A shrimp like you, the strongest? Hahahahahahahaha-ha!" he managed to get out, his roaring laugh echoing across the empty tunnels. Naruto just glared at him, wanting very much to hit him for laughing at him, but held back by his intimidating size. Knowing that the creature before him could likely squash him like a bug, the boy had to settle for dirty looks and angry huffing as the Shikima king laughed and laughed on at his bold declarations.

Finally, Seikima managed to get his amusement under control. Still chuckling, he regarded the boy before him with a new light in his eyes.

"Uzumaki Naruto, eh? I like you, kid," he commented, his voice no longer a booming, threatening sound of thunder. "You're just as brash and hotheaded as my daughter. I don't think you'll ever manage to become the strongest, but I've seen stranger things happen in my life, so I'll give you the benefit of the doubt... and I'll even let you keep the contract with my vassals. Use it well, for summoning the right one in the right situation can give you a swift and decisive victory over even the strongest opponent. We Shikima are fearsome fighters in our own right, but when it comes to Yuwakujutsu, none can stand before our might. Remember that..."

"Huh? What is 'Yuwakuwhatever'?" Naruto asked, blinking. Seikima chuckled again at the child's apparent cluelessness.

"You will find out - when you are older, normally, but given the contract you just signed, I cannot speak for my vassals and their actions. After all, you are what most Shikima females would find positively delicious..." he replied with a light snicker. He then pulled out a scroll, dipped a taloned finger in the small pool of Naruto's blood that had formed where he'd been summoned and scribbled something on it, snapping it shut when he was done and handing it to the boy.

"Here, take this," he said. "Normally, to access the Shikima's zone in Makai, one needs other... rituals... to open the door. But given your... unique situation, you will only need that scroll and your chakra. I expect you to drop by and visit me sometime, little brat. You amuse me, and I would not mind seeing you again..."

With those words, the Shikima king gave Naruto a last smirk and disappeared in a poof, the smoke temporarily blinding the blond boy.

After the demon had departed, Naruto sat there for several minutes, staring at the spot he had been occupying. Then, his brain finally unfroze itself, and he pointed a shaky finger at the empty space.

"Hey! I'm not a brat, and I'm not little, you blue freak!" he shouted.

Oh, if only he had known.

But then, that loincloth was covering the truth...

(A/N: DONE! And yes, I'm evil. How else would I get the idea of a summoning contract with hentai tentacle demons and whatnot? Now you know what the title stands for... :p

Until next time, R&R! GH out.)
