A Ninja Reborn

Hatake Kakashi is dead.

He had lived a long life, all the way till he was 60. That is impressive considering how ninjas life expectancy are. But regardless, Hatake Kakashi is dead.

So why does he hear voices?

Kakashi tries to open his eyes but he can't. He tries to talk to the garbled voices, but all he does is make stupid sounds. 

Kakashi tried to used his chakra but something seems to be blocking it. He would try to unlock it only to feel pain.

For some reason, he can't help but cry when he feels pain, when he feels uncomfortable, when he's hungry, anything really. Kakashi tries not to cry but it was as if his body refuses to and he would cry. Hard.

One day, something besides crying finally happened. Kakashi can now open his eyes.

He was in some sort of crib. He can't get up, he tried mind you. The room he was in reminds him of a nursery.

Why was he here? And where is this here?

Kakashi cursed himself as he suddenly started crying. Again he can't stop himself. Instead, the wails grew louder.

The door in the nursery opened and a man came in. Kakashi noticed the man wearing a strange outfit. A blue long sleeves shirt, a pair of pants, and a red scarf. No one Kakashi had known wore fabrics like that. It seems softer, akin to what nobles in the Fire country would wear.

The man hold Kakashi, it was then he suddenly realize he had shrunk. The man started shaking him softly, hushing him. Strangely enough, his cries started to quieten.

"Hmm. Did you woke up little one?" The man said as he grab a bottle. "Hungry?"

Before Kakashi could protest, try anyway, the bottle was put on his mouth. It was as if his body is on autopilot. He sucked the bottle, feeling his eyelids grew heavier.

The man gently placed him back on the crib a few moments later. Kakashi felt himself getting more and more tired. Just as he fell asleep, he heard the man's voice once more.

"Goodnight little Kakashi."


Kamihara Kakashi, that was his new name.

It took him a few days to learn that the man is his father. His new father. That was a strange thing to know.

It took him much longer to learn other important information.

He is a baby, only a few months old. It took a while for him to get a glimpse of what he looks like and what he saw shock him. He looks exactly like he did before, the only differences was him missing his scar.

He also figured out he was no longer in his world. For one thing there was no Konoha, not even the Fire country.

Instead he had learned that he lives in a country called Japan. Japan has much more advanced technology until Kakashi caught a glimpse of the calendar.

Another thing he had discovered were quirks. Unlike chakra, not everyone has quirks. Kakashi would, hopefully, recieved his quirk by the time he was four.

And finally he learned that his father is rich. Not just rich, but noble kind of rich. He lives in what they called a traditional house, but his father had all sorts of expensive stuff. Like how he had easily told a servant to buy Kakashi a milk formula that cost about 50000 yen.

Yeah, his new dad's loaded.

Kakashi knew very well his father's money would be useful. After all, you can do a lot more stuff with money in a world like this.


Kakashi loves, at the same time hates, being a baby. Being served with anything you need was fun. Not being able to do anything was not fun.

He was just glad he can finally walk, even if he trips a lot. He cannot wait until he can do what he used to do. And suddenly Kakashi realize he has to relearn just about everything. 

Just great. Note the sarcasm.

Kakashi felt himself tumble and land in front of a door. He never seen that door before. Against better judgement, he walked inside.

It was a training area.

Kakashi has stars in his eyes when he saw it. Everything in there is a ninja's wet dream. He can see shurikens and kunais in one area, different kinds of swords on another.

Kakashi made his way to the kunais, cursing his small legs for taking so long. Grabbing the kunai, he felt the familiar feeling of the sharp weapon on his hand.

It had been so long.

He threw the kunai to a target and...missed. He tried again, and again, and again. Every single one miss the center. Kakashi huffed, feeling his energy drained. His new body needs training.

"Impressive."

Kakashi stiffened and spinned around, only to trip at the action. In front of him was his father, smiling at him.

"Those shots were impressive Kakashi. Most can't even throw the kunais right as beginners."

I'm not a beginner. He wanted to say. I have been doing this longer than you. But he can't say that, his father won't understand.

"How about I teach you how to do the basics? What do you say Kashi, want to learn martial arts and how to used those weapons?"

He knew how to used those weapons, thank you very much. But Kakashi knew he can't just suddenly knew how to do those things without proper training. His father would be suspicious. Atleast this would give him an excuse as a fast learner.


Kakashi is three when he learned about heroes. They remind him of ninjas, except they were different. They protect the people, but unlike ninjas, they don't kill the villains.

And like all kids his physical age, he has a favorite hero. It was not All Might or Endeavor. Not All Might because, while he reminds him of Naruto, he was just too bright for his taste. Not Endeavor because, quite frankly, he is a jerk.

No, his favorite hero is no other than..

"Edgeshot!"

"What?" His father asked, confused at the sudden declaration. Kakashi looked at him with stars in his eyes.

"Edgeshot is my favorite hero!"

Kakashi noticed how his father seemed flustered at that statement. Weird. Regardless, Edgeshot is his favorite hero.

Why? Because he reminds him of Kakashi. That and he's a ninja. So really, it wasn't surprising that his favorite hero is Edgeshot. His father seems pleased for some reason and bought as many Edgeshot merch as Kakashi wants.


A month before his fourth birthday in this world, his chakra was buzzing. Kakashi knew he can finally used his chakra soon.

Heading to a quiet corner, he plucked a leaf from a nearby tree. Kakashi tried to apply chakra to the leaf.

Key word: tried.

No matter what he does, his chakra won't work. He knew his chakra can be unlock soon, but Kakashi was getting impatient. He wants to be able to use his chakra again.

He went back inside dejected when his father called him for dinner.


Kakashi felt different a week before his fourth birthday. For some reason, he felt more energized. His left eye also stings a little.

Kakashi trudged to the dining room. His father was about to greet him when he froze.

"Kashi, what happened to your eye?"

That made Kakashi blink. His eye? What was wrong with it?

He quickly run towards the nearest mirror. Whatever they told you about that day, Kakashi definitely did not scream. Alright maybe a little.

The sharingan was swirling alive on his left eye. His left, unscarred eye. That's when Kakashi felt his chakra. He tried to do a chidori, and he succeed.

"Looks like you have your quirk." His father said, grinning at him. Kakashi can't help but grin back.


"What a peculiar quirk you have. There is no record about it or anything similar at all." The doctor said, looking at Kakashi's records. "It's not even a quirk mutation."

"It says here that young Kakashi's quirk has some sort of connections to the elements. His eye, however, is a mystery. As far as I can tell, the eye is permanently like that. The eye also appears to have a connection of sorts to his quirk. That's as far as we know." The doctor said, frustrated at the lack of explanation towards the boy's quirk.

"What should we call his quirk then?" His father asked, albeit surprised at the answer about his son's quirk.

"Chakra manipulation." Kakashi said glaring at the doctor. It was as if he was daring him to say no.

"Hmm. Chakra manipulatiom, eh?" The doctor echoed. "The most we could do is let young Kakashi explore his quirk. Strangely enough, people tend to have an innate understanding on their quirks. If young Kakashi says it's chakra manipulation, it's chakra manipulation."

"That is the only option." His father agreed.

Kakashi grinned, atleast now he can used the innate understanding as an excuse to any jutsus he'll do. His week gotten even better when his father had gifted him with a custom facemask for his birthday.
