Last fought and sacrifice

Being inside the infinity fortress was like a maze, it didn't even help that gravity here kept changing and the rooms kept moving.

Naruto use his shadows to scatter around as right now he could feel one part of this whole entire dimension he was in there at the center of it all was a demon who had control over this place.

Naruto was running to the source of it and once he got there he could see a woman, she wore a black kimono, she had pale skin, her eyes were covered by her long black hair.

She hold a biwa in her hands, 'so that is the demon who has control over this place.'

Muzan then appeared right next to the female demon, "so you finally made it... Naruto it's been a long time."

"Yes it has," naruto said as his shadows try to went after the two but a wall block them, "huh?"

"Please, why should we keep fighting, you know all I want is that girl nezuko, tell me where she is and I'll let you go," Muzan said as Naruto did not buy it.

"So you can finally conquer the Sun and try to kill me along with all the other demons in Japan? We both know someone like you will never conquer the Sun," Naruto said as he wanted to kill him after all this time.

"Have to make this harder on yourself, you should know by now that you're in this dimension, you have to face someone else who can control this pocket dimension," Muzan said as both his last upper Moon demons appeared.

Naruto saw one on the right was the one he fought earlier that managed to escape thanks to this fortress, the other was with pale skin, blue lines on his face and pink short hair.

"Upper Moon three Akaza and upper Moon one Kokushibo, well let's get this over with," Naruto said out his shadows appeared again and went directly at them.

However more walls appear between them blocking his attack, "no matter I can easy...?"

Naruto stop himself as he turned around and saw Kokushibo with his blade out ready to decapitate him.

Naruto quickly jump away as Akaza had pop out of nowhere and Naruto dodge his attack which was almost a quick punch in the face.

Naruto where he was standing quickly went out like a pillar and then the force of gravity caused him to go upside down along with the other both upper rooms.

Naruto quickly realized the reason what was going on here it was that demon, her instrument she was playing with allow her to bend the room to her will.

"You have got to be kidding me," naruto said to himself annoyed, now realizing what was going on here.

"BLOOD DEMON ART!" Naruto yelled as the compass appeared right behind him, raising a sword to North.

Akaza charge at him while Kokushibo stay behind.

Naruto release freezing breath that cost the whole entire room to get cold.

Akaza feet got frozen and when the table seen to have turned the room had flip around causing everyone to go to the next side of the room.

Naruto look at the female demon, "seriously! can't have me this moment!?"

Naruto continue to fight off, using his shadows to block and defend himself as it was hard to direct attacks at them with the room coming around.

This went on for a couple minutes until... The room stopped moving.

Naruto smirk, looking over to see the females instrument have became frozen.

"But how?" She asked by surprise as the shadows kelp the other two demons busy now without the rooms moving around them.

Naruto was able to jump over to her and grab her instruments, "next time look at all your surroundings!"

Naruto destroy her instrument which cause her to panic as she looked down at the shutter pieces.

"NO! NO! NO! NO!" She scream as she was trying to pick up the pieces but they would not be able to put back together.

"It was made out of wood, I'm sure you can get a new one," Naruto said as he looked around the infinity fortress.

Naruto look at the other two demons who are still battling the shadows that were keeping them away from him.

Naruto had enough of this as he used his shadows on all three of the upper moons and kill them.

Because of the female demon had no longer control over the fortress it began to collapsed.

Naruto panic but quickly got out, both him and Muzan were now in the middle of nowhere, both see each other, Only a being few feet away as both were in a pile of rubble.

Naruto surprised to see he was back at his old mansion that was destroyed.

Muzan have realized his plan was a big mistake but it was too late as a Shadow barrier form around them.

"What are you doing?" Muzan demanded to know.

"After all the trouble you cause, it's now just you and me, Muzan kibutsuji, one on one!" Naruto said as he had enough of Muzan hiding and want him to fight him.

Muzan had no choice but to go and fight, the two went at it, Naruto wasn't using any of his special tricks on Muzan as even though he could easily kill him, naruto wanted to beat him up by hand-to-hand combat.

"I can't believe you were willing to go all the way this far for immortality!" Naruto said as he hated Muzan for everything he had done.

"You know it was my dream for protection! To finally become perfect," Muzan said as he will never stop until he finally gets what he wants.

"It's people like me that will never stop defending what is right!" Naruto told him as he gave him a back kick but Muzan grab it and toss him to a few feet but Naruto remain on his legs as he only slide back a few feet away.

"Do you really believe you can defeat a natural disaster?" Muzan ask as Naruto look confused, "people go on with their lives after earthquakes, rain storms, and so many other things happens and lose lives but they still go on with their life's, that is what I am a natural disaster, people don't go after them but why do the demon Slayer Corp and you demons keep coming after me? I do not understand it and I don't really care because I have become so sick of it all! I am going to finally end it."

"That seriously what you think you are?" Naruto ask as they continue on fighting.

"You are more stronger than I thought! You're not that weak dead last you once were," Muzan told him.

"It's because I will not stop, until you are gone! I do not care what it takes, I am not going to let you win!" Naruto told him as Muzan was running out of options.

"Then let's see if you can dodge this!" Muzan ask as he punch Naruto hard in the gut that went through but his hand did not came out from the other side.

"What the hell?" Naruto ask as he did not understand what was going on.

It took only a couple seconds but Naruto suddenly felt something, "AAAHHHHH!"

"That is my curse!" Muzan said as he purposely hit Naruto in the gut and let his arm be absorbed into his body so he would be infected with his curse once again.

Naruto however was resisting but the curse felt like it could have overtaken, "no... I!"

Naruto grab Muzan arm, it started to cause his arm to go deeper into Naruto body.

"Won't let you win!" Naruto yelled as his words struggle to come out of his mouth.

"Blood demon art! MERGE!" Naruto yelled as his ability cause Muzan body to be absorb into Naruto's body.

Naruto dropped to his knees as he felt so much pain with all of blood of Muzan inside of him.

Muzan was now speaking through his mind, "YOU FOOL! THIS CAN'T STOP YOU FROM THE CURSE!"

Naruto smirk, "you forgot one thing I merge you with me, this can actually cause any damage to me and to you as well, if you use that curse on me you will also be infected with it and die alongside me."

Those words had made Muzan in fear but quickly calm himself down as he realized there was probably here with naruto plan, Muzan would be able to take control over Naruto body in short time.

The shadow barrier came down as he was screaming, it took a bit of time but kurama had ran over to Naruto.

"Naruto what's wrong?" Kurama ask as Naruto grab kurama by his risk and look at him with a lot of pain.

"MUZAN KIBUTSUJI IS INSIDE OF ME!" Naruto yelled as he used his blood demon art to show him what happened.

Kurama couldn't believe it what had happened but there had to be a way to stop this.

Naruto had made the mistake of what he had to choose that he believed to defeat Muzan, he should have just killed him on the spot but it was too late now that they were merged.

"Kurama there is a way I can stop this but sadly I won't be coming back, at least we finally won, Muzan will be dead along with the rest of the demons under his curse, please tell my family I love them," naruto last words before he uses blood demon art to show what his plan was.

"Naruto you can't do that!" Kurama told him as he didn't want it to happen.

"I'm sorry, but this is the only way, thank you for all you have done, goodbye brother," his last words to kurama and then a black cocoon form around naruto and disappeared.

"What the heck did you show him?" Muzan demanded to know as despite them being merged he did not see the plan.

"Muzan it's time for you to get some SUNLIGHT!" naruto yelled at the cocoon disappeared of the shadows and they were in a different spot where the sun was already coming up.

Muzan panicking as he tried to control Naruto's body but Naruto himself was still a very powerful demon as the curse and control could not take full effect on his body.

"It would have taken a few days before you could have gotten my me under your full control," Naruto said with a little laugh knowing he had finally won.

The sun came on to his skin and started to burn as he screamed very loud with his eyes glowing bright.

All the strength Naruto had caused him to explode into dark shadows leaving nothing behind but his clothes on the ground.

There was nothing that remain of Naruto or Muzan body's.

In the afterlife

Muzan was looking back and forth wondering where the heck he was as he heard the sounds of laughter and turn around to see Naruto the way how he was when he was only 13 years old.

"WHAT HAVE YOU DONE?!" Muzan demanded as Naruto was relax.

"It's so good, I finally have my human body back even though im dead but so are you, I'll be taking great pleasure dragging you into hell with me," naruto said as he was ready to rot in hell forever but was quickly stopped with a hand touching his shoulder.

Naruto turn around and saw it was the old third Hokage Hiruzen, "huh? Wait what are you doing here?"

"Where do you think you're going young man, you're not going to hell, hell has no place for good people like you," he told Naruto as he smiles, Naruto was surprised hearing this.

The two disappeared into the light, Muzan was left alone as the flames of hell surrounded him and slowly engulf him finally bringing a end to him.

In heaven

It was peaceful in heaven as Naruto was all in white with the old man standing next to him.

"I don't understand, why have you brought me here? I mean I know I have done some things but if I do deserve..." Naruto was cut off by Hiruzen.

"Do you know how long I waited for you after everything I watch?" Hiruzen ask.

Naruto did look guilty as he did care about the old man and his legacy but he had destroyed it.

"Naruto you brought the end of chakra, you destroy my village and for all you did that you believe it was worth, I think you made the right call," Hiruzen said as that surprise him.

"Really? I mean... don't get me wrong I did believe what I had done was right but why are you forgiving me? It was your home and village, a lot of things you built there are now gone," Naruto wanting to know the truth.

"After everything you have done for what you believe, humans not deserving of chakra, how much they abuse it and how much they let it control them, you saw how much the Shinobi world had truly failed, I was at least glad I was able to help you one last time in that dream," Hiruzen said as Naruto quickly remember the dream he had when he woke up a few hours ago.

"Wait you were really there? But how?" Naruto ask.

"Well spirits can enter dreams to say something important after all you would not wake up, no matter how many times you were told, I had to do something," Hiruzen said as he hug Naruto.

"Thank you, you help me a lot I could have lost my family if it wasn't for you," Naruto said as if it wasn't for him, naruto might have lost his family because he was still asleep then and those demons would have killed them.

"Yes, indeed, don't worry they're all fine and safe," Hiruzen said.

"You mean Hannah, ciel and Alois and..." Naruto got caught off again.

"Yes all five of your miracles along everyone else thinks you," Hiruzen said as Naruto gave him a tight hug as he was relieved to know that everyone in his family was all right.

Despite what has happened now he will forever watch over them.

To be continued

Okay yes Naruto dying because he sacrificed himself, I was making a bunch of Naruto FanFictions and I was trying to think how can I end this?

With both my no hero and my golden fox demon fanfiction I wanted to give them each different endings.

So I decide for this ending here I would make Naruto's sacrifice himself to save his whole entire family from The demon King Muzan kibutsuji.

Now Naruto is back with the third Hokage as they are reunited in heaven.

There is still one last chapter and I hope you're all looking forward to it.
