Disclaimer: I do not own Naruto

Just a fun idea for a story I had come to mind and as far as I know no one has ever done a story like this before on this site. The pairing will be NaruSaku Sorry, that's my preference even if it wasn't final, other pairings I have ideas for but others I do not. Don't like don't read. Takes place after the Tsunade retrieval arc , after Sasuke leaves but before Naruto leaves with Jiraiya.

Also, I'm doing this story mainly for the fun idea it is but the more people want it the more I'll write for it.

Thank you for reading.

Prologue

The sun had risen again on that fine day in the hidden Leaf Village. It was shaping up to be a perfect day.

Maybe that should have been a warning of what was to come.

The citizens of the village went about their business with civilians walking the streets shopping at the markets and ninja leapt from building to building effortlessly. Other ninja were training such as Naruto Uzumaki.

Naruto had been training with shadow clones trying to perfect his Rasengan to the point where he could use it one handed. He had even gotten Kakashi to help, although Gai had tagged along

"C'mon, c'mon!" he muttered to himself before finally doing it.

Grinning at his accomplishment, him stabilizing the combination of wind element and rasengan, it vanished in his hand, popping like a bubble.

He looked at his hand bewildered "Huh?"

Then there was a poofing sound all around him as the shadow clones disappeared all at once. Naruto looked around in confusion, he hadn't canceled the flow of chakra to his clones and he wasn't suffering from chakra exhaustion, so what happened?

"Naruto, is there a reason you stopped?" Kakashi asked curiously.

"I didn't! Everything just stopped by itself" Naruto said still confused.

"That's strange, I should probably take a look" Kakashi said lifting up his head band and opening his left eye only to have a look of shock takes its place.

Gai and Naruto looked at each other after seeing the look on Kakashi's face.

Naruto was the first to speak "Kakashi sensei is everything okay?"

"My eye…" they heard him say

"What about your eye?" Gai said beginning to worry.

"I can see normal through it" he said turning towards them, as they looked into his left eye they didn't see the usual red sharingan, all they saw was a normal black eye.

Elsewhere

Sakura walked through the village market to get more ingredients for Naruto's food pills she couldn't help but feel optimistic, maybe it was because of the beautiful day, either way she felt like nothing could bring her mood down.

And then a ninja landed on a table right beside her.

"What the heck!?" she said, even a genin never fell down while jumping rooftops. But then she realized that it wasn't just this ninja but others as well as her seeing and heard more falling made her realize something else had happened. She ran to the ninja who had fallen beside her. She could see that he had a broken arm and leg and probably some ribs, which was weird because normally a ninja's chakra would have automatically made them more durable, like a reflex.

"What happened?" she asked.

"I don't know, I was on my way home and next thing I knew I was falling" he said through pained breaths. Sakura began weaving hand signs for a jutsu to dull the pain so she could proceed with bandaging him up and setting the bones. However as she stretched her hands forward towards the man's injuries there was no green glow to her hand like normal. Shocked and wondering what she did wrong she tried again, and again nothing.

She didn't know what was going on, both her and Ino had taken basic medical ninjutsu classes! but she still had been trained for situations when they couldn't use chakra, either because of exhaustion or undercover. So she pulled out some medical supplies from her bag and began to get to work. "This is going to hurt" she told the man.

A few minutes later Ino and Shikamaru ran up to her. "Sakura, why are you treating him without proper jutsu?" Ino asked.

Sakura shook her head "I tried but I can't get my jutsu to work"

Ino and Shikamaru gained puzzled looks

"Here let me try" Ino said going to the fallen ninja and weaving hand signs only to have the jutsu not work either.

"I don't understand, why can't I use my jutsu?" Ino asked gaining a look implying to her friends that she was close to freaking out.

Shikamaru looked at the injured ninja who had fallen out of the sky, some were worse than others and had bones sticking out of them and some people had put blankets over those that had died. He then looked up to the sky. It was well known that ninja used chakra to leap across rooftops and could even use it to glide a bit, so Shikamaru could only think of one explanation for what had happened.

He turned and saw a cat sitting on the edge of the road and he quickly made the hand signs for his shadow possession jutsu, but instead of his shadow bending to his will it stayed where it was. A shocked look came across his face. His Chakra was gone.

Elsewhere in the Land of Fire

Itachi sat on a pier at the edge of a vast lake. They were on another money collecting mission for the Akatsuki. Apparently a crime boss's grandfather had thrown a large amount of his money into the lake to hide it from leaf ninja who were attempting to shut him down, and since the money was gained illegally, he couldn't hire leaf ninja to get it for him. The treasure was apparently gold coins and the current boss had promised 25% of the goods inside. Where the treasure was in the lake was uncertain, so Kisame had been down there for the past two hours carefully combing the lake floor for its location, and why not? After all Itachi couldn't breathe under water.

Suddenly his already bad vision blurred even worse and he closed his eyes in reflex. When he opened them again he noticed that his vision was as good as it had been when he was younger before he unlocked his sharingan. Itachi was very rarely at a loss and this was one of those moments

Underwater

Kisame swam through the deep, annoyed at having to do all the work.

Suddenly it was like a pulse gone through his body and he saw his blue skin begin to return to a normal color. Then things got worse.

He couldn't breathe!

He realized that somehow he had lost his ability to breathe under water! Frantically he grabbed at his neck only to find his gills gone.

As quickly as he could he began to swim towards the top as he tried to keep from drowning only for the darkness to envelop him as he neared a boat close to the top of the lake.

He couldn't help but think. 'How Ironic'

In the Land of Rice.

Orochimaru had taken Sasuke for some training with just them. As they stood in a clearing they practiced with the sword.

"Not bad Sasuke" Orochimaru said as he lifted his Kusanagi to parry Sasuke's attack. "However you are still making a mistake in your style"

Whatever that mistake was Sasuke would never hear. Before him Orochimaru went bug eyed and then made a gasping sound as he began to whither and not soon after, where Orochimaru had stood was now a mummified body.

Sasuke looked at it in horror. He desperately tried to activate his sharingan only for it to fail and his vision to remain the same. He then went to leap in the tree only for his chakra enhanced leap to not come and he only leapt the average height for his 13 year old self. He tried to brace himself for a potential attack with chidori, only for his hand to remain lightning free. He then tried to use his curse mark only for nothing to happen.

At an unknown location.

Black Zetsu moved to a new location to spy on yet another Jinchuriki. When he too felt something change. He held up his hand only to see his black body beginning to melt as his chakra faded.

"I'm… Melting?" he said with fear in his voice.

As he began to become a puddle he was able to let out one more word. "Mother…"

So what do you think? I thought it would be interesting to see what if the Naruto characters we all knew and love had to learn to live without chakra. There will be action, mystery, romance, and general chaos.

To explain some of the things that may confuse some of the readers is that if Kakashi lost the chakra in the sharingan then it would probably return to it's original black color. Itachi's bad eye sight was caused by chakra and his MS so the damage was reversed. As for Orochimaru's death? He has been switching bodies with him needing his current body to stay alive, so no chakra = No longer able to live.

So what do you think the Naruto characters will do now that the worlds chakra is gone? This won't affect normal civilians so the ninja will have to learn a whole new way of life.

Let me know what you think.

Thank you for reading and have a nice day!
