The Forbidden Existence

There are a few things that you must know before reading the story. First off, there will be elements of the Anime/Manga Campione in this crossover, possibly more. Secondly, how I portray Naruto is going to be a bit OC, but explanations for his behavior will be revealed later on. Lastly, I will not be changing anybodies race until further notice.

Chapter 1

Humans were not alone in their vast world, silently governing them were beings beyond normal human comprehension. Ranging from creatures of lore and divine existences whom have occupied the vast world along with humans, often mingling with them. Mythology was what humans deemed as stories of old that were created from their ancestors inability to understand, in reality, they were partially correct. Humanity had long been exposed to the Mythological World as many from the latter now called themselves, wishes to separate humans from their very own world, the Mythological creatures had manipulated them into believing whatever was necessary to keep their existence secret. And thus that was how myths were born, resulting in creation of legends and religions of various kinds.

Gods were divine existences that governed the world from their holy world separated from regular mortals, that was what many had believed for centuries. And gradually those beliefs in their existence had swelled them with power, due to this, many Gods and Goddesses truly became some of the strongest beings in the known world. That was how the world was governed, with a secret world hiding in the shadows of humanity's ignorance. There were humans who lived with knowledge of this world of Mythological being's existence. Families of humans whom held abilities relating to the various Mythological Factions were always apart of this strange world.

Naruto Uzumaki was a curious individual, that curiosity of his was what usually got him involved in unpleasant situations. Sometimes Naruto wondered if he was cursed with horrendous luck, he would always get into situations that almost always resulted in painful outcomes. Naruto was the son of Minato Namikaze and Kushina Uzumaki, being married into the Uzumaki clan, Minato and Kushina had given birth to a son. Naruto took after his father with spiky blonde locks, bright blue eyes, and a round face. But, a few traits he inherited from Kushina, like her unorthodox ways of handling situations as well as her horrible luck.

Currently Naruto was running for his dear life, chasing after him was a man in his early forties with tanned skin and a lean build, fierce brown eyes that were narrowed in rage, short black hair and a long beard with both showing signs of graying. Dressed in a red-brown shirt with short, tight sleeves cut very much like Egyptian kalasiris. A matching girdle which was trimmed with a tassels and embroidered elaborately, and lastly simple brown sandals. Nothing seemed strange aside from his odd choice of clothing, there seemed like no reason to run from him, aside for the fact that he held a lightning bolt in one hand and he was also riding a lion. Yes, a lion.

As wind picked up and the sky darkened, lightning roared from above followed by bellows of lightning. Rain showered the earth bellow, as Naruto ran pellets of water struck him. Weaving through an abandoned building, a massive bolt of lightning ignited the sky, it obliterated the building Naruto occupied. Nothing but a steady melody of rain was audible followed occasional bellows of lightning and thunder. The man whom had been chasing Naruto stood there with his hands crossed, and a smirk present on his face.

"Foolish mortal, did you believe yourself able to escape from me?" the man asked as his arrogance leaked into his voice. "Me, the mighty storm god Ishkur?"

No response as expected, the God known as Ishkur turned away from his handiwork and he was followed by his faithful companion. Not even three steps were made before he suddenly stopped in his tracks, turning around swiftly, Ishkur barely dodged a swift slash aimed for his head. As the lion charged his attacker, Ishkur frowned in annoyance as he eyed the battered blonde whom had attacked him. Though Ishkur was positive that his attack would have killed him, he did not take into account that his old age had weakened his might considerably. Even though he was a God, common belief of his immortality was a outright lie. Though he did seem to be immortal, like a human he was born and eventually he would die. Except unlike a human, he possessed a behemoth span of life that could be compared to immortality. Now with an aged body, Ishkur, being one of the worlds oldest God's, like many in his pantheon were slowly dying off. As it was expected of a pantheon filled with the first Gods to ever roam this world.

Even though he was dying off, Ishkur was far from weak. With divine blood still flowing in his veins, Ishkur held immense power that could only be rivaled by fellow Gods and only surpassed by two Dragons. Ishkur's thoughts were interrupted when his companion was sent flying towards him, ducking in response, Ishkur was caught off guard by a fist sent towards his stomach. As the attack successfully connected with his stomach Ishkur did nothing by frown once more in annoyance, that attack did nothing but annoy him further. Growling, Ishkur reached forward and grabbed hold of the blonde's outstretched hand and yanked him forward. Delivering a painful strike to the boy's stomach, Ishkur followed that blow by channeling lightning into the lad. As yellow light consumed him, Ishkur tossed him aside like a rag doll. Smoke arose from the body of the blonde, horrendous burns now decorated his body, Ishkur did not even bat the blonde an eyelash.

It was foolish to challenge him, a God, to a fight. Whatever this mortal was attempting to prove was utterly foolish, after all, whoever heard of a mortal defeating a God in open combat. Preposterous, no humans could ever surpass the God's in combat. Turning around once more, Ishkur waved his hand and was about to teleport away when he suddenly leaned to the right successfully avoiding a thrown blade. Eyes narrowing, Ishkur turned to face the blonde once more. Bloodied and battered, he stood, blonde locks dyed in crimson red with his clothes ripped and torn in various areas covering minimal parts of his body. Ishkur continued to eye the blonde with annoyance and a small hint of interest in his narrowed eyes, whatever this human was attempting to prove was clearly dear to him.

"Tell me mortal, what are you attempting to do?" Ishkur asked with mild interest in his tone. "You cannot beat me, yet you still stand even after I have defeated you."

Silence was returned to him as Naruto grunted in pain and his wobbly arms pushed him off of the ground, pain burned his entire body. It felt as if every cell in his body was on fire, the unimaginable pain was now a reality. Even so, Naruto pushed on. Taking a shaky step forward, Naruto lifted his bloodied head and stared straight at the God. Fierce blue eyes remained strong even if every other part of Naruto's body had already gave away. "To prove..." Naruto managed to mutter through estranged pants. "That we... humans... are not... inferior... even if we are... we can still fight..."

Ishkur was silent at first, but a fit of laughter escaped his lips. "Haha! Amusing! A human who wishes to challenge a God merely to prove that your pitiful race is not helpless, truly amusing!"

Reaching into his torn pockets, Naruto pulled out a small vial of liquid that had been safely protected and ripped off the cork. Chugging the contents into his mouth, Naruto's wounds instantly healed and all signs of damage vanished aside from his destroyed clothing. Blood that coated him was washed off by the continuous downpour, Ishkur stopped his laughing and shook his head. "You may have healed yourself mortal, but I am the mighty storm God and oldest of them all. I am Ishkur, the Sumerian God of Storms and bringer of Rain!" Ishkur boasted with a smirk on his face. "By what means do you, a mere mortal believe that you can defeat me!"

Naruto did not answer immediately as he tossed the bottle that once help Phenex tears away. He had gone through a lot of trouble just to get two bottles and he had already used one of them, how he had managed to survive those attacks were not because of his skill, far from it. Naruto had only survived because Ishkur had underestimated him and barely used his divine powers, any sane person facing these odds would have ran long ago. But, Naruto was not sane, he was just too stubborn to run. No matter what he would prove to the world that humanity was not some weak fools that they could take advantage of because they were so weak.

"Ishkur, the Sumerian God of Storms, Weather, Hurricanes, Thunder, and Rain." Naruto began as he used the knowledge he had acquired from his long studies. "Utilizing lightning to strike down his enemies, you were depicted as a warlike figure whom had vanquished rebellious lands like the wind. Married the Goddess of Grain, Shala. Hailed as the Lord of Abundance, and feared for bringing famine, your name has been engraved into history but forgotten through time."

Ishkur's smile that had widened as Naruto was speaking about him quickly shifted into a frown as he heard the blonde's last statement. Turning to face him, Ishkur knew what he spoke was true. He and the other Sumerian Gods had been forgotten by a majority of their subjects and their only followers had dwindled down, like them, the Olympians had lost much belief as well, but their names had been quite famous thus canceled out the negative effects of losing their place in humanity. The Sumerian Pantheon on the other hand had lost much belief and recognition which resulted in their influence dwindling. With their influence dwindling down, it effected their strength very much, even if he wished to hide it, what Naruto spoke was true.

"You speak bold words, mortal." Ishkur said with a blank stare. "I grow tired of this. Prepare yourself! For your insolence, I shall strike you down like the enemies I have long ago!"

Like that Ishkur charged, sending a volley of super powered lightning bolts at him, Naruto used whatever strength he had, as well as enhancing his legs with magic, and dove to the right. Grunting in mild pain, Naruto quickly sprinted away from Ishkur, a series of explosions lit up behind him. Ignoring that in favor of running, Naruto quickly stopped in his tracks when a rampaging lion bounded towards him with it's wicked sharp teeth and claws showing. Looking around, Naruto jumped into the air and landed on a tree, hopping from branch to branch. It wasn't long before another series of violent bolts of lightning struck his surroundings successfully blinding him for a few seconds. And it only took those mere seconds to strike Naruto with another vicious bolt, screaming in pain, Naruto grit his teeth and braced himself for a hard landing.

Ishkur appeared before the downed blonde and a smirk found its way onto his face once more, Ishkur was quite angry at Naruto for undermining his powers. Even if his Pantheon had been forgotten, it did not men they were weak. He would show this impudent mortal that they were still powerful!

"Mortal, I shall show you the true might of us Sumerian Gods!" Ishkur bellowed as he stretched his arms to the side and spoke, "Agana samu Iskuru mar abatu katmu muzzerru! Alaku ahu babalu ni barutu dananu adanu birtu mar pahzu landunu sina Kasum! (Come heavenly Boar who destroyed our enemies! Come and bring me divine strength that protected the glorious lands of Mesopotamia!)"

As golden light danced across his body, it shot into the skies and took the form of a massive boar. Charging downwards, the boar aimed towards Ishkur and the God smirked. Though he did not have to go through this process to use this power, Ishkur wished to make a show of his power and thus created this spectacle. Just as the boar was about to make contact, Ishkur's eyes widened when he was shoved out of the way before Naruto was the one who had been consumed by the glow of the golden boar. An explosion rocked the earth and Ishkur brought his arms to shield his face from this marvelous glow, once it had died down, Naruto stood there with a golden hue surrounding his body. His bright blue eyes shown brighter than the stars with a golden outline now present in them.

"Thanks for the power, Lord Ishkur." Naruto said as he focused on the shocked God. "With this, I shall bring you down!"

Ishkur was still shocked, he had been too late to stop a fist connecting with his stomach. Flying backwards, Ishkur managed to regain himself but Naruto did not relent as he continued to charge forward. Ishkur knew that this power of his, had enhanced the users strength dramatically. Not only did it boost the physical prowess of a the user and whomever it was used on, it also would rekindle the flames of courage if lost. This was one of his three great symbols, along with his Lightning Bolt and Lion, the Boar represent his ferocity in battle and would be the power that allowed him to defeat other Gods.

The heavens around them roared in protest as Ishkur willed wind, lightning, and water to fend off against the fast approaching blonde. A raging storm quickly formed around him and Ishkur too charged. As his lion pursued after him, Ishkur met Naruto in battle as godly powers clashed. An explosion of golden brilliance enveloped the area around them completely obliterating everything caught in it. Once everything became visible once more, Naruto stood there before Ishkur with his fist raised. Ishkur's eyes widened in shock and fear.

"How did you come out unscathed!" Ishkur demanded as he clutched his chest wound in pain attempting to stop the flow of his divine blood.

Naruto smirked in response and pulled out an empty vial of Phenex Tears, "I had two bottles for extra insurance. Now, I shall end your existence, Lord Ishgur!"

Ishgur did not know what to say, he had been bested by a human. Once more his arrogance had been his downfall, and then his shock was replaced by amusement and strangely enough, happiness. As a smirk formed on his own face, Ishgur welcomed the next blow with open arms, "Come and strike me down, mortal. You have proven yourself and your mortal brethren, you have proven yourself well. May I know the name of my worthy opponent?"

"Naruto Uzumaki."

Ishgur had been defeated and slayed by a human. It was as simple as that, as he vanished, the land that he had plagued with famine now lost the curse of doom. A smile had found its way onto his face as a shower of golden particles carried him into the heavens where his beloved Shala awaited him, looking down at the human whom had defeated him, Ishgur had done a final act. For millenniums since Shala had faded, Ishgur had been lost. Plaguing whatever lands for no known reason, Ishgur had allowed his grief to control him. But this human had been able to free him of this curse and he had died a honorable way, in the hands of a warrior.

With his final breath, Ishgur spoke in a commanding tone fit for a deity such as himself, "Naruto Uzumaki, with my final words I grant you the title of Campione! A champion of humanity, a Godslayer who wields the power of a God as a defender!"

Gods were powerful beings, the death of one impacted many factors in life. As humans viewed Gods as immortal all powerful beings, not only would expect a mere mortal to slay a deity. How could they, Gods wielded unimaginable power that could wipe out armies in a mere flick of their fingers. And now, the birth of something that no one would have predicted had came to pass, the birth of a Godslayer.

A Campione - a Godslayer - is a supreme ruler.

Sine he can kill a celestial being, he can therefore call on the sacrosanct, divine powers wielded by the Gods.

A Campione - a Godslayer - is a lord.

Since the power to kill a deity is in his hands, he therefore looms over all mortals on Earth.

A Campione - a Godslayer is a transcendent.

Since of all mortals who live in the world, none can assume power to match his!

Chapter end

Hope you guys enjoyed this chapter and please leave a review. Now, I wish to explain somethings about this chapter. One, as you may have noticed, I changed devil with transcendent. Since DxD there really are Devils, I tweaked the word a bit but it still has a similar effect. Also note that a human is not able to match a God due to the sheer power difference, and a human slaying a God has not been heard of in this fic.

Divinities

Heavenly Lion: A Lion with great power that makes for a powerful beast with its claws and fangs much like the wolf Fenrir's which can harm Gods.

Radiant Boar: A special ability that allows the user to enhance their physical strength into Godly proportions and thus making them invulnerable for a limited time. Not only does it grant physical boosts, but it strengthens courage and ferocity in battle.

Elder Lightning: Lightning wielded by the oldest of Storm Gods that can outmatched many other Gods with its sheer power.

Weather Control: A special ability that allows the user to manipulate the weather around them to a great degree, instantly creating natural disasters and storms much like the Sacred Gear Zenith Tempest.

Also, note that I researched about the God before I placed him in the story. Google him if you want to know more and also note that the idea of remembrance that powers the Gods/gives them power is a concept that I thought would fit very well in this story. As Hinduism is the oldest religion giving them astounding influence and power thus Indra and Shiva as well as other Hindu God's being in the top 10 strongest in the DxD universe. Anyways, please leave a review and suggest some powers that you want me to grant Naruto and what God he should kill later, thanks for reading and bye!
