'Something big thinking'

"Something big talking"

I am just a normal guy working at my dream job, as a person who creates military grade weapons and technology. I'm pretty damn important and rich and also pretty intelligent and ingenious. I could probably create and arm a whole miltary fighter plane on my own if given 5 years and a shit load of money. However I am more into creating iron man type stuff which so far I have been unsuccessful at. I was working at my job with some new interns...that the federal agency I work at has decided to hire. Then a stray missile is fired by some idiotic intern who was half asleep on the control panel who was also supposed to warn me if a light pops telling us the obstacle can now be targeted. The missile blows up in the test lab I am at while I was busy repairing an obstacle the missile had to clear. Sirens sound, I taste blood from my mouth, and I stare at my body somehow, one intern screaming and shaking his bag of chips violently from pure panic. This is what all the interns and workers walked into after lunch break and a huge explosion that shook the laboratory. There's fire everywhere and suddenly I see nothing.

'Fuck, I've just been decapitated by my own missile.' Is the first thing I say when I see a vast expanse of white. But then again I can't say that because I have nobody to speak with, so if anything that's what I was thinking I guess. Why am I talking to myself anyways? Am I that bored? I hope that intern is fired as soon as possible. He's a safety hazard from just sleeping.

After a while a light flashes and I peek through a hole the light has created in probably the space-time something or wherever people go after horribly dying to one of their own missiles. I don't know where I'm at so I'm not going to bother describing it. I realize that if I fall down a light hole I would be reborn, as for how I know this...it comes mainly from my instincts. After I look at the disappearing and appearing holes it seems this world is a ninja world from my favorite and only anime I have ever watched which is Naruto. I could tell because there is a whisker birthmark boy in one of them who is obviously Naruto. The world looks real now and isn't an anime world anymore. I look around for some good opportunity to fall into one of these holes and be reborn. Eventually the loop repeats and Naruto is back in the hole of possible rebirth. Well not as Naruto but as another character related to him because I see Naruto is already born and being held by his father. So it is great that I won't be taking over someone's barely born body because that would be creepy as fuck. What would happen instead is that I will be creating an entirely new body and I know this again from my instincts. I look around and decide to be born as Minato's younger brother. I mean I see Minato alive and he looks like he is 5 years old or something. This rebirth shit will probably shake the story line to hell if I'm reborn but on second thought I'm not going to look at holes with my possible future life for eternity. So I jump in, and I have got to say birth is disgusting and beautiful. I feel slimy and everyone looks at me as if I'm mentally impaired or something because they are slowly talking and talking slowly so I could understand them or something? Which by all means I should be mentally impaired because I was born less than a minute ago. I see no father looking figure around me. My brother is crying and I hear my mother's heart rate monitor having a constant beep until the hospital staff shuts it down with a sad look on their faces. I could really need some help right now. I'm being bottlefed by an inexperienced nurse who has the bottle almost choking me. My brother meanwhile is obviously depressed because my brother's blue eyes show he is extremely sad. He holds me and utters "Your name is Kai Namikaze. Mom and Dad are dead and we are orphans as of right now. Don't worry, I'll take care of you from now on." My brother starts crying and I join him. Mainly because I try talking but when I see it doesn't work I cry at my inability to do nothing.

I wake up. Scanning the area I see my brother sleeping. We are no longer at the hospital so we can only be in our late parent's home. Then I hear a knock on the door. My brother doesn't get up. I need to alert him now! I will use a baby's ultimate weapon. Cry extremely loud and hope someone does something for you. So I start crying again. Minato slams the alarm clock and I giggle. Minato groans and opens the door. As soon as he sees Hiruzen the third Hokage he quickly stands up straight and gives his full attention to the now young Hokage that pretty much looks how absolutely no one thinks about him when they think about the third Hokage in my previous world.

"Lord Hokage! I apologize for not opening the door quick enough and for my current state."

"Apology accepted. I want to let you know that you and your brother will receive an orphans fund each and that due to the orphanage being full you will keep your house and won't have to pay for your house since your orphans fund will automatically deduct the expense. You will have around 10,000 ryo combined. Use it wisely."

"Yes sir I will make sure to use it wisely!"

"Minato stop being so nervous around me. I'm not going to punish you or anything. You just went through the death of your parent's 2 weeks apart. If you need to talk to someone come to my office and I will help you as best as I can. Your parent's were good friends of mine so I'm happy to help their children."

"Alright thank you for the help I really need it. But for my brother's sake I have to be strong."

Sarutobi chuckles and leaves after giving Minato the 10k ryo and some advice. Minato looked at me with caring eyes and said "I'll go get you some new toys as well as any necessities we will need. In the meantime, be a good boy."

Five Years Later

I was standing at 3 foot 6 inches tall. I looked like a blond, blue eyed, 5 year old of pure happiness or possibly anger because I still haven't figured out chakra.

"Kai! What are you doing!?"

"I want to learn how to use chakra!"

"I know you want to be strong but if you unlock the use of chakra as early as clan heirs then you will have a lot of work and I kind of want to let you live a happy childhood."

"No way I'm doing that! I want to learn badly. I also want to learn seals!"

"How about this? If you do good with seals then I'll help you with your chakra."

"Fine."

So my journey into seals began and oh boy did I love seals! You can do so much impossible things you can't in my old world which leads to so many damn ideas. It was the best decision of my life and a week later, Minato was forced to help me use my chakra. I was able to unleash my chakra after three attempts and Minato of course was excited.

"Kai! You are so good at using chakra! Now you begin your path as a shinobi. Now we have to work in chakra control."

"Onii-San does Chakra control lets me use chakra better?"

"Yes it sure does and it is very helpful."

"What does chakra control let you do Onii-San?"

"It lets you eventually walk on trees and water."

"Woah!"

"I already mastered that and I am working on some more advanced chakra control excersizes that I won't tell you about till you become a genin probably."

"That's so unfair! That's like 5 years away!"

"Haha well don't worry about it."

As you may or may not tell I have to act like a child because I am a child. I don't have the mental capacity to think about complex thoughts like what I was doing in my previous world yet because my brain is still developing. However, I am maturing faster than anyone my age and I have more knowledge and experience than most my age as well. Chakra also does many things for me. Like I was able to walk on water after 3 moths of training and after 9 months my chakra control was almost as good as my brother's who revamped his training schedule and got ahead by a lot again. My brother decided to teach me about my clan whose Kekkei Genkai gives us much better reactions, instincts, and speed by much more. Unfortunately we are the only two people left in our clan. Then something incredible happened. My brother got a girlfriend who I pranked the first time I met her when she came to our house because I thought it was my brother who took my seal kit by accident. All I did was drop slime on her...

"MINATO! Who did this?"

Minato sweat dropped and said "Uhm calm down that was probably my little brother Kai who tried to get me because I took his seal kit by accident today."

"Get out here Kai! Someone wants to meet you." Minato said after augmenting his voice.

Upon hearing this I run out of my room and then get slapped upon entering the living room.

"Who did that? That hurts. I mean even Minato Onii-San doesn't slap me for pranking him."

"That would be me!" Said a very angry Kushina.

"Uhm...Minato Onii-San who is she and why was I slapped that hard? This isn't a funny counter prank and I might have lost a tooth."

"Kushina meet my brother Kai. Kai meet Kushina who I'm currently...dating." Minato and Kushina blushed at the same time.

"Woah when is the wedding? Will you guys have kids soon? I promise I'll be the best uncle ever!" I say cheekily. They both blush and Kushina screams out "WE HAVE ONLY BEEN DATING FOR A WEEK SO GIVE US TIME." I laugh while Minato mumbles something along he lines of "Ima get you for this."

After that day I was put in the academy because that's the only way to become a qualified lead ninja. Of course I was able to tease Minato and Kushina about wanting some private time together to do stuff...that Jiraiya, who is Minato's sensei, told me about. Minato encouraged me and helped me with my chakra control while Kushina helped me with Taijutsu. Sort of...mainly her trying to punch me as much as possible, but hey on the bright side I got access to my clan's taijutsu. The academy was something that I hated but couldn't avoid. The academy was so easy I could have graduated in a few months but Minato said no. He also said go make friends but everyone there was idiotic because they were mostly dreamy civilians. The only interesting thing taught at the academy were the three academy jutsu they taught us. There was the replacement technique, the clone jutsu, and the transformation jutsu. Which I got each of them down in a whole month to the point where I can do them without hand seals.

10 years old

I graduated at 9 and am now 4 feet tall and I am quite proud of that because no one else in my class graduated and I am one of the tallest and to add to that there were no teams I could be in. Therefore I am going to be working with chunin squads until I get a field promotion or a chunin exam which is unlikely because there is a war about to start. In these 10 years I have to say my mental capacity went up so I could do even more complicated things now comparable to what I was doing in my past life. Using chakra and seals I could probably create weapons for only myself which I have because I realized I'm a natural born sensor. Using chakra signatures I'm able to lock on to it and guide a weapon over somewhere, if the weapon has my chakra signature it will work. Eventually this will give me a lock on missile of doom I'm still working on. But right now explosion tags are still better and efficient than these missiles because I haven't been able to make the missiles bigger yet without going into rockets. So this is going to take time to make them work. Minato with the help from me and Kushina can now teleport with his special three pronged kunai. I am also working on my teleportation kunai things and I have to say it's difficult reducing the chakra cost by a lot. Right now it's not entirely useable until my chakra reserves grow to high chunin level because my chakra levels are genin level right now due to me spending more time learning fuinjutsu as opposed to ninjutsu. At most my teleport technique can be used as an emergency escape right now.

Well enough about me now onto the B rank mission on hand.

"Kai I need you to smoke this place up. We're going to infiltrate and take the information scroll without combat. On my signal smoke it up."

"Smoke pellets ready waiting for signal and the room is now sealed."

"Now!"

The smoke is released from the pellets. The ninja in there were not ready and pass out from the thick poisonous smoke. The room was sealed so it was impossible for them to escape. I equip a smoke mask and go inside the room. I see 4 Iwa ninja on the floor unconscious and I put a seal on each of them to keep them knocked out. Searching through the room I find the scroll and drag the ninja out.

"We can take prisoners sir! One of them is Jonin level and the rest are genin level. The smoke I released on them was poisonous but not lethal."

"Good job Kai! Kill the genin and apply a full body paralization seal tag on the Jonin."

Taking out a kunai I slit the throats of the genin and take anything useful there. As for why I am so calm it would have to be because my first C rank ended up being a bandit extermination mission so I'm used to death. I found condoms on one of the seal scrolls they have which is not very useful for me but useful for my brother. Blood can be smelled so I seal the genin in body seals and give them to the Jonin in charge of this mission. He takes them and stores them in his pocket. I wipe my knife on the paralyzed Jonin and tie the Jonin up.

"Done Kai?" I nod and he finishes up checking on the Jonin and taking all his weapons. "Good because we are leaving now."

As we walk back to the village I sense five chakra signatures awaiting us past a mountain path. "Sir there is an ambush awaiting us."

"What do you suggest we do?"

"I can teleport back to the village."

"That's wise. Alright things are going well for your field promotion mission right now."

I put my palm on the Jonin and teleport him back to the Hokage's office which sucked up half of my chakra. Then I teleport there myself without using as much chakra but having to do hand seals for something special I want to do. A quarter of my chakra is used up and I arrive.

In a yellow flash and a clap of thunder which wasn't very loud, I am back at the Hokage's office. The thunderclap effect comes from doing hand seals to creat wind chakra and using it to power the teleportation jutsu.

"Well Kai. The Jonin in charge of your field promotion has decided you are ready for chunin rank missions upon getting chunin level chakra reserves. Until then you are chunin in name but still basically genin until then. Congratulations!"

With a smile on my face I bow and say "Thank you Lord Hokage!" I receive the chunin flak jacket and run back towards my house.

Upon entering my 4 bedroom, 2 bathroom, 1 kitchen, 1 living room, and large basement home I smell some food cooking and Kushina singing. I was noticed extremely quickly by Kushina though.

"Oh Kai you're back. I'm in the kitchen cooking right now." Kushina said.

Minato appears right next to me after teleporting home and says "Woah Kai your a chunin now!"

"Yup big brother! I became chunin just a few minutes ago."

Kushina comes running from the kitchen and sees me with chunin jacket. "Kai congratulations! You're a chunin now!" I look at her hand and see a ring. "Congratulations on getting engaged sister-in-law."

Minato and Kushina blush extremely hard upon hearing me. While Kushina says "Yeah it took him this long to propose to me and he finally did it today but we won't get married till we are 18 though." I stare at her and Minato and I say "Have you guys done what Jiraiya-sensei has told me couples do?" They blush and Minato slams his hand at his face while saying"That pervert! Now sensei corrupted my younger brother. No we haven't done that Kai." I chuckle and move onto more pressing matters.

"Anyways Onii-San and Kushina-San are you guys going to cook a giant dinner now? I'm extremely hungry from eating just meal bars during those consecutive missions. Kushina's food is always the best food." Kushina snickers and says "I'll make your favorite food today so go wash up ya-know? You smell like blood right now." I immediately comply while going to Minato's room and leaving the scroll with condoms in his drawer. I know he's going to kill me when he finds out though which will happen by the end of today probably. I go to my room and grab my change of clothes and go shower. Upon coming out and eating I go to sleep while hearing Minato's angry scream from his room. Yup life is peaceful as always right now.
