Son of the true sky
Disclaimer I don't own Naruto or Percy Jackson and this is the only disclaimer I will give due to the fact that it's all one story just multiple chapters and this is the only one that should be needed so yeah there is my one and only disclaimer for this story.
So yeah ignoring that last part for now let me say sorry I haven't updated my stories and am starting a new one I just have terrible writers block and just had like five different story ideas I will only continue two of these stories until they end then I will do the other ones one at a time just review and tell me which ones you want me to continue. Anyways on with the story.
20 Years before Naruto is born.
"I'm tired of all this. First my son takes away all my power and leaves me only nothing, and then my grandson decides that I can't go anywhere near my wife even though he knows damn well that nothing bad will happen I won't crush the earth and the people on it that's my wife damn it I wouldn't do that to her. Screw all this I'm taking a vacation let's see how they like starless nights for the next oh let's say 20 years." Ouranus rants. He then proceeds to make himself a mortal shell and travels to a different dimension doing as he promised and taking the stars with him for the next 20 years. After he manages to travel to another dimension the sky primordial uses the mist to make everyone he had been there the entire time accidently giving himself a girlfriend in the process of changing every ones memory. The name he gave his mortal shell Minato Namikaze.
33 years later at the Valley of the End or VotE (for those that didn't know that already)
"Sasuke I refuse to let you leave I'm bringing you back to Konoha whether you like it or not. Even if I have to break every single bone in your body and drag you back you will be coming back to Konoha with me." Naruto yelled as a blue cloak like thing appeared around him wait a minute, blue. 'What's going on isn't my cloak supposed to be red whatever I don't have time to be thinking about this.' Naruto decided to leave it be and focused on the fight to bring Sasuke back. As soon as he ran towards Sasuke he noticed he was a lot faster than usual. As Naruto gets close enough to Sasuke he goes for a headshot but Sasuke seemed to have the same idea and punches right back. Both the boys get sent flying into the two statues, as Naruto stands back up he notices that Sasuke is charging up a chidori so Naruto decides to charge up a rasengan. The weird thing though is this one was different than usual it was strange it felt a lot more powerful than usual he decided that like the cloak he would deal with it later. As Naruto and Sasuke's attacks connected a giant purple black sphere surrounded the two. (you know now that I think about it didn't it kinda look like a bijudama)
Inside the sphere
"Sasuke I don't understand why you would want to go to someone like Orochimaru for power and right now I don't care I will make you pay for betraying the leaf village!" Naruto yelled out. All of a sudden the two could hear someone clapping. As the two turned to see who else could have possibly been in there with them they see the figure of the fourth hokage.
"Well said my son. Well said indeed." The fourth hokage (Ouranus) said.
"T-tou-san y-your my tou-san, the fourth hokage is my dad. Yatta! I knew I was awesome. Wait a minute aren't you dead, doesn't that mean I am dead ahh man." Naruto said slightly depressed.
"No you two are not dead I will explain how I am alive later. I am here because you my son are coming back to our home world with me. Oh and Sasuke if you swear on the river styx not to betray Naruto ever again I will allow you to come with us as well and before you start talking about bullshit like you need to kill Itachi and you can only get that type of power from Orochimaru let me explain that I am much stronger than that snake and I could kill Itachi with a snap of my fingers for I am a primordial an immortal being older than the gods I can help you obtain power that no one on this planet can ever even hope to come close to." Ouranus stated.
"Deal/sure thing pops" said Sasuke and Naruto respectively.
"Although I do wonder what happened to you dad I mean you sealed up kyubi and then vanish so what happened?" Naruto asked. Sasuke leaned in curious to know as well.
"Well you see that was simply a mortal aspect of me that ended up dying I had not been expecting that so it took me a few years to gather my conscience and put it back together. Anyways it's about time to leave so Sasuke please repeat after me, I Sasuke Uchiha swear on the river styx to never betray Naruto Uzumaki-Namikaze." Ouranus said giving Sasuke the oath to say.
"I Sasuke Uchiha swear on the river styx to never betray Naruto Uzumaki-Namikaze." Sasuke said and a large thunder clap was heard.
"Alright lets go oh and whenever we get there I will transfer to you to the skills and powers you two would have gotten if you had stayed here and that will of course include information on how to use said new power. Also Naruto you will learn of my true name after you reach a camp that you will be dropped off near its called camp half-blood. Sasuke you will be Naruto's body guard so protect and aid him whenever he needs it." With that said they walk off into a portal Ouranus had created to take them to his home dimension.
Percy Jackson Universe
The day was clear not a in the sky, just two boys falling from the sky very fast, thank the gods they had a lake there to break his their fall below them.
"Holy shit we're gonna die!" yelled Naruto as they fell. Naruto was panicking and trying to swim upwards through the sky and he was partially succeeding (-_-|… anime logic). To the side you could see Sasuke with his back to the lake arms behind his head and legs crossed. "Sasuke how the hell are you so calm about all of this when we are falling to our doom!"
"Hn." Sasuke replied impassively taking a quick glance at the water he then looks back at Naruto "Hey Naruto."
"Yeah?" Naruto replies wondering what it was Sasuke was going to say.
"I hate your dad right now." Sasuke once again said impassively as they twist their body in the air to land pencil dive position. "A lot." *splash*. Their bodies then hit the water with barely a splash.
To be continued?... that will be up to you guys leave a non dick review about what you guys think. Also don't worry future chapters will be longer.
