Prologue

                                    

                                          
Naruto was running really fast, trying to reach his best friend as fast as he could for he overheard the plans of their enemies from his team. They had defeated Kaguya years ago, and right after that, a war erupted, one that nobody had known of until there were bombings on all the countries. It didn't take them long to realize that Kaguya had awakened the guardians of this world and had disrupted the balance. She had changed the guardians to be following her will, so they were planning to destroy this world of ever Kaguya died. They were using meteors to bomb the countries and try to make it self-destruct and collapse on itself.
                          
Naruto continued running with the other tailed beasts that he saved in chibi mode on his clones, Sakura following him from behind. "We won't get there fast enough!" Sakura exclaimed.
                          
"No! I will!!" Naruto shouted as they came to the end of the forest and saw Sasuke standing on top of a huge meteorite that had already fallen. He was glaring at a giant, deformed creature made of all of the elements of the earth. It looked a bit like the ten tails right before Obito awakened it. Naruto saw the creature form a black orb made of concentrated chakra on its hands that were actually ten on it's back. "SASUKEEE!!!" Naruto shouted, and right before the creature threw the orbs, Naruto performed the Substitution Jutsu and swapped places with Sasuke, receiving the hits.
                          
"NARUTO!!" Sakura and Sasuke shouted in fear for their Hokage. Their team was crying until the dust cleared, and they saw Naruto with most of his body torn, but he was still in the shape with a human because they realized that a lava-like substance was filling the holes of his body. Naruto had nine red-orange tails on his back and was surrounded by red chakra. Naruto was panting and glaring at the creature.
                          
"Kurama, any suggestions on how to defeat him?" Naruto growled. He was glaring back at the creature and jumped when the creature swiped at him.
                          
"There are two ways that I know of to defeat him," Kurama suggested. Naruto nodded to tell him to continue. "The first one is for sure gonna stop this destruction, but may also destroy the whole planet. It will for sure kill The tailed beasts, too. The second one will stop all of them, but it will kill you and is tailed beasts."
                          
Unfortunately, Sasuke heard this. "Naruto, no!" Sasuke was unfortunately still too far away and couldn't get close because he didn't know how to fly unlike Naruto, and he was out of chakra. Sakura was healing him while her team was standing watch like guards to make sure nothing interferes with whatever Naruto was going to do.
                          
"Tell me," Naruto said sternly, skillfully dodging the attacks of the creature.
                          
"The first one, you have to merge my chakra with the nature chakra you absorbed and all the other tailed beasts, and release me to fight that thing," Kurama replied, sighing. "However, now that you have both halves of me, you'll release two of me, and we'll merge and possibly lose control. I may destroy everything with all the power I have."
                          
"And the second choice?" Naru asked, landing a punch on the creature's face.
                          
"Merge with me and all the other tailed beasts," Kurama replied. "The price is that you sacrifice all your chakra to us, and we will become the ten tails together. Our old man will come and grant you the rinnegan, and you will have full control of our chakra, but we will die. All the tails and possibly you, as well. We don't know if your body is able to handle the strain, plus that first attack earlier damaged you greatly. I only provided chakra to make your life longer for a bit, but if the merging is successful, you may survive."
                          
Naruto's eyes widened. "B-but you'll die!" he exclaimed.
                          
"Naruto, I'll die either way," Kurama replied, looking at his host sadly. "You're gonna have to make a choice, kit."
