This is my first Fan Fiction. Hope you enjoy.
Disclaimer - I don't own anything from the Naruto/Fairy Tail anime/manga, all I own are plot twists and my original characters.
"Heavily monstrous voice"
Chapter 1 - Death of a friend, End of a Goddess
As Kakashi blocks Sasuke from attempts to block Sasuke from getting killed by Kaguya, his body suddenly collapses in pain, from a stab wound that wasn't fully healed earlier and Kaguya manages to hit Sasuke.
"Sasuke!" Naruto and Sakura scream as their dying comrade starts to disintegrate.
"Dobe, come here, I need to give you something", Sasuke says as he is dying.
Once Naruto makes it over to Sasuke, Sasuke taps Naruto's forehead with two fingers and they both enter Naruto's mindscape.
Inside Naruto's Mindscape
"What am I doing here?" Naruto asks as he looks around.
"Dobe, come here." Sasuke says as he comes out from the dark.
"What's going on Sasuke?" Naruto inquires.
Once Naruto gets over to him, Sasuke says, "I'm giving you my Sharin-rinnegan and all the knowledge you need to use it, as well as my power from the Rikudo Sennin. Make sure to use them well."
"What? Sasuke, no, you can't die! I-" Naruto starts.
Sasuke interrupts with, "Dobe, listen I'm dying. It's too late for me now. I'm also giving you a pair of Eternal Mangekyo Sharingan that I'd like you to give to whoever you end up with. This is my last wish. Goodbye, Naruto."
Back in Kaguya's Dimension
"Dobe, I now realize that your path of hope, rather than revenge, was the right one. No matter what you do, never abandon that path. Sakura, I'm sorry for never returning your love, but I just never had it in me to feel love. And Kakashi, I'm so sorry for betraying your trust and becoming a traitor to the world, but at least now I can finally make up for it, Goodbye, everyone…"
"Sasuke, noooooo!" Naruto screamed out to the heavens. "I'm going to kill you, bastard!" Naruto suddenly activated his rinnegan and screamed, "Susanoo", and suddenly charged at Kaguya, sealing her just as she was opening a portal and getting sucked into the vortex, and ending up in a random dimension out there somewhere.
"Kakashi-sensei, how can we get Naruto back?" Sakura asks.
"I'm sorry Sakura, but I think that both Naruto and Sasuke are now lost to us forever." Kakashi states in a depressed tone.
In the mountains on a world called Earthland
"Kurama, you there?" Naruto inquires.
"I'm here, Naruto." Kurama responds.
"Where are we, and how do we get back?" Naruto questions.
Kurama answers with, "I believe we are on another world, Naruto. And it is impossible for us to get back, I'm sorry Kit"
"It's ok Kurama, I'll just have to live my life on a new world I guess." Naruto states.
Naruto then exclaims, "Kurama, I'm sensing someone in danger, let's go!" And just like that, Naruto sets off on a new adventure.
