Author note: sup guys Rikudou Naruto here my second story I hope you will enjoy the story. So this story will be a crossover with 3 universes high school dxd, percy Jackson, and Naruto. But instead of them all being separated I will have the Percy Jackson verse merge with high school dxd, seeing that the Greek gods do exist and so on in the dxd verse. The main character will be Sasuke Uchiha, now Sasuke's character in the fandom, some people hate the dude, others are meh with him, and other absolutely love the dude. I choose Sasuke because his character is interesting to me, and I'am rather in depth with his character in itself his thoughts and so on. Now than let's get on with the story don't forget to REVIEW.

Sasuke Uchiha the last survivor of the Uchiha clan, is laying on the grass with a peaceful expression on his face as he had his eyes closed and his hands his left hand had bandages wrapped around it. He had both of them behind his head while snoring softly.

He in question has spiky black hair with a blue tint in it it hangs over his face as the left side of his head is covered by his hair making his eye not visible, with his eyes open Sasuke has one onyx eye while the other one is a rippled purple eye stretched across the entire eyeball with tomeo's in it, he wears a black cloak over a black shirt and pants with a white belt and white bandages wrapped up to his knees.

The Uchiha in question is simply put bored out of his mind, after the whole chino ordeal he got bored because there was nothing to do the violent ninja times were over so he had nothing to do, and he quite enjoyed the peace, so he decided to visit orochimaru wanting to know what the mysterious snake was up too, only for the snake Sannin to tell him he is rather busy with a new project so he left he could clearly hear that the man is busy.

So he went back on the road trying to atone for his sins, no matter what Naruto said that he had forgiven him, he himself didn't he couldn't not after what he had done to all the nations. As Sasuke stood up after hearing a screech from a bird. The Uchiha sighed in annoyance as he stood up and glared at the sun that is blinding him right now. Getting used to the light he looked in the blue sky wi some clouds and saw the bird that is still screeching, he whistled to the bird who heard it and looked at him as he or she began flying towards him.

As the bird landed on his hand Sasuke saw a piece of paper tied around the bird's leg. Sasuke untied the piece of paper around the bird's leg and let the bird fly away. With a sigh he opened the piece of paper." Pretty sure Naruto wrote this." Sasuke muttered as he recognized his friend's bad writing.

Sasuke sighed, as he lit the paper in fire and burned it as he dissipated the fire. He gained a serious look as he gathered chakra in his rinnegan, he focused it in front of him as he released the chakra creating a portal in space and time." This better be worth it Naruto Kakashi." The Uchiha thought as he walked in the portal. The portal closed behind him and this was the last time the elemental nations would hear from Sasuke Uchiha.

There will be mourned for the shadow of the leaf, his name will be written on the memorial stone as a hero, next to itachi Uchiha. His funeral will be held in a few months, Sakura Haruno will be devastated, Naruto will blame himself same with Kakashi hatake. Some will celebrate finally happy that the Uchiha clan has totally vanquished.

And with that said Uchiha Sasuke has completely disappeared from the elemental nations up to a different universe were gods, dragons, devils, angels, titans, Demi-gods, yokai, and so much more will be standing in his way. But there is a saying about a Uchiha." Never cross a Uchiha." A simple statement, but it is a promise who ever crosses Uchiha Sasuke will receive no mercy of him

Dimensional gap

XX

The dimensional gap, a space with nothing but endless colors a space were time flows different than normal, a space were two of the strongest beings in existence life. Ophis the infinite dragon god a shape shifting dragon who is the third strongest in existence. And great red the dragon of dragons, the true red dragon emperor, and the strongest in existence.

These two reside in this gap of space and time. Well that was so until great red refused to leave and ophis wanted the place to be quite it was her home after all. Remember when I said that she can shapeshift she shape shifted in a human Loli girl in goth clothes, yeah dragons with their weird tastes.

Anyway Ophis wants this place to be quite, and with great red pestering every time in the gap. She would leave soon she would gather new people to get the great dragon out of her silence.

As both dragons were bickering with eachother, they both heard a boom and turned around to see a young man fall from a purple portal. Both dragons looked at eachother ophis with the same expression she always has emotionless. While great red looked intrigued, how a human survive because no normal human could survive a second in the dimension gap."i'am going to check that out, from what I can sense it is just a normal human, that should be teared apart by the pressure of the dimensional gap, how interesting." Great red grumbled as he flew towards the Uchiha, as Ophis followed with a quirked eyebrow.

Both dragons arrived at the floating motionless avenger, who had his eyes closed. Great red narrowed his eyes than a insane grin spreader across his face." Muhahhahahahhahahh, I finally found one of them." The dragon of dreams stated while laughing out loud while flying in the air in circles.

Ophis looked at her greatest rival." What do you mean, I do not understand Baka-red." Ophis said with a stoic expression and a emotionless tone. Red in question gained a tick mark, he absolutely hated that nickname." Right I forgot you hid like a coward snake bitch, did you forget that one war from that world." Red stated with amusement glinting in his eyes as he looked at his so-called rival who also had a tick mark on her face. After her fuming she looked at great red with the same look."You mean from those ninjas with weird eyes?" She asked him as the dragon nodded to her.

She could still remember the day when two titans of clashing power could be felt dimensions away and three other beings also, they called themselves shinobi, and later on became gods with their power, one was already a goddess she had no doubt they could all wipe the floor with her in seconds, she and red were arguing with eachother and were trading blows when they sensed the power coming from that dimension. They watched the entire war folding out and were shocked to see a primordial entity being used like a puppet to these people. She could still remember a titan of a samurai those in Japan he was shrouded blue was fighting against a wooden golem. The other one was a man fighting against the same samurai but with a purple color, and a Orange nine tails covered in aura, and this wasn't a average nine tails no this one was as tall as a mountain even taller than great red himself.

Each clash she could feel it as it happened the day of yesterday, a purple orb of destruction and a arrow with black flames similar to the goddess Amaterasu had clashed with the man's shield of darkness that didn't even shatter by impact nor the power and so on. They watched as the man in the blue titan like samurai had achieved a even higher power unimaginable to them he became a literal god. He clashed with a men covered in a aura of blood and survived the destruction what looked like a attack similar to red himself.

They watched the entire war till the final fight that forced them to stop watching as the power was too powerful and shocking for them, they could still sense the fight going on from their dimension, in the end she couldn't handle it and began hiding from their insane powers,One was light the other darkness, the one was the moon the other the sun.

And now one is laying right in front of them, she could feel the power rolling of him in waves while it wasn't as much as golden fox, she still could feel a lot of it." It sensed similar to chakra of the yokai faction, but more potent and complete." Ophis commentend in her usual monotone.

"Indeed it does, and I can sense it this being is a being of darkness, yet he still holds light in his hart a never ending one at that, so in sense he similar to the moon. But I can also sense the power of him rolling in waves, but at the same time he seems to be not there." The dragon of dragons said confused, he could feel the power, but not Sasuke's presence even infront of him.

"Weird that should not be possible, or did your sensor prowess weaken Baka-red." Ophis stated to great dragon who roared at her creating cracks in the dimensional gap. Ophis glared back at the great dragon." What should we do with him Baka-red." Ophis asked the dragon who lookedat her while grinning savagely." I shall fight him of course." He declared proudly to the dragon god who rolled her eyes at him." No we can't risk the dimensional gap be destroyed by you two fighting Baka." Ophis said causing the dragon of dragons to roll his eyes." Fine, we shall just send him to those weaklings let them deal with him, but this will be a promise ophis I shall fight him no matter the cost I shall fight him." The dragon said with a sadistic grin on his face, he was going to prove that he was the strongest in all existences. Ophis glared at her rival how she wanted to him to leave so bad." We shall do that." She said in the same montone.

"My my and you didn't even ask me to vote." A voice said from behind them as there stood chaos a man with a face with no eyes and mouth, he wears a white suit and a white hat, he looked rather thin." Chaos." Ophis simply said to the god who nodded to her." Chaos, how long has it been a few millennia when I last saw you, did you forget about our spar." Great red said to the creator, who merely chuckled at the dragons." maybe some other time red,first we need to look at the matter at hand here, from what I could gather his name is Sasuke Uchiha a shinobi a powerful one at that, and a reincarnation of Indra otsutsuki." Chaos stated to the two dragons.

Both dragons narrowed their eyes." So he is the reincarnation of the sage's eldest son interesting indeed." Red commented as Ophis nodded to chaos." So my proposal is we send him to Japan as that is the only language he speaks." Chaos proposed to them as both dragons nodded." That is plausible, but which city?" Ophis asked." Kuoh supernatural lurks there." Chaos said amused." Plus the mist wil cover him and, the human will only see a shooting star." Chaos said, as both dragons nodded in acceptance. With a mere word of portal a portal opened beneath as the Uchiha passed through it and the portal closed, as chaos looked amused that you couldn't see he looked at the dragons.

"So who is up for a game of cards?" Asked with a smile that you couldn't see as he held a stack of cards in his right hand. Both Ophis and great red groaned the man always won no matter what you did, illusions didn't help he broke free of them, and he never sleeps so dreams also never helped.

Japan Kuoh 9:22 pm

Sasuke never liked surprises he never did, so when he woke up in alley near apartment building he was getting attacked by unknown creatures. One is female from what he could guess from the top of her building as she has her boobs showable she also have purple short hair, and blue eyes as she looked with a insane expression at the Uchiha, but her under part of her body looked lizard like. The other one has a bull head and a body of a man that is very muscular, it looked like it is blind and it is fuming in rage. It stood as tall as a house

He sighed in annoyance as his expression turned in a pissed off one, he hadn't eaten, he is thirsty, and didn't know where he is, when he got back he would whoop Naruto's ass." I'am mad and you two are the best test dummies that there are now, so don't die quickly." Sasuke said in a cold tone as he unsheathed his sword and glared at them with a cold look.

The Minotaur roared in rage as it began charging at sasuke with a enraged expression it went for wild swipe at the Uchiha who jumped over the swipe and balanced on the huge arm of the monster as he ran up it towards his neck, as the monster went to smack Sasuke like a bug , the Uchiha was gone from its vision." Die." Sasuke simply said as he cut the Minotaur's head off. The entire body vanished in gold dust as the head is only left on the ground." That was weird." The Uchiha thought he never saw something like that in his entire life.

Sasuke looked the spot and saw that the stray is still there he let a cold grin appear on his face, that send shivers to the stray's spine." Your still here that's good, but there will be nothing more but a speck of dust of you when i'am done." The Uchiha promised the paralyzed stray." And I haven't even unleashed a single drop of killing intent, nor did I flare my chakra, how pathetic." The Uchiha thought with a shake of his head."katon: Gokyaku no jutsu." Sasuke said in himself as he spat out a fireball the size of a house at the stray.

The stray in question couldn't dodge nor move, she is literally paralyzed in fear she saw her life flash before her eye, she looked at the beautiful ball of inferno heading her way in a trancelike state. As the fireball hit her she let out a silent scream, as she was burned alive to nothingness she felt her entire being on fire.

Sasuke appeared behind her as he held his hand in front of him and began absorbing the fireball into himself thank to the rinnegan's abilities as he saw the fireball dissipate leavening only a gust of wind that made the dust in front of him disappear into the air. With a sigh jumped from the ground to the roof, and looked at the full moon." I need information and fast." The Uchiha muttered to himself. He didn't know where he was, but he was going to make a promise." I may not know where i'am, but anyone who decides to stand in my way for me atoning for my sins wil pay. I will protect the innocents just like Naruto would, that is a promise of a life time, neh Naruto." Sasuke vowed to himself as he began roof hopping.
