Chapter 1: Chapter 1: I'm Might Guy'son... damn
{Naruto's World will be in an Alternate Universe, as the MC's own birth will change the entire course, so throw your canon knowledge in the trash, it doesn't matter here }
MC POV
Hi, my name is John, a typical salaried otaku, worked like a workhorse to pay my bills and use what was left to buy food with what little was left (damn capitalist system)
I had a good family, I had great grades in school and college, at school I beat up some bullies, they thought I would be easy prey on the first day, but they went back to their homes with black eyes and a tooth missing from each one.
This didn't make me worry enough, the kids' parents were bothering them, but my mother told them to get screwed, the teachers and the principal were always quiet because the school I attended was the same one my mother attended, so they knew my mother could turn into a demon when angry.
I sometimes donated a little money to an orphanage, I even played with the children, some idiots embezzled money from the orphanage when I found out I reported it to the police... I hit them before calling the police.
Now I'm dying, I saved a child from being kidnapped... I had only one regret in this life, it was watching half of Naruto, I liked the anime but I never continued.
But wait a minute… shouldn't I be dead? how can I think and why am I in a dark place? Turn on the damn light!
''Because I allow you to think, mortal,'' said an authoritative and dominant voice, I suddenly found myself in an office with an elderly man in formal attire.
3rd POV
''Let me think... are you God or ROB and are you going to reincarnate me?'' John asked, he could already understand that the person in front of him was a divine being, so it must be the typical isekai or he will tell you to work for him, he doesn't want it to be the second option.
''*cough* yes, I'm ROB and I'll reincarnate you, but the world is already decided'' Spoke ROB giving a fake cough, hiding his surprise and irritation.
'Damn, because of those fanfics everyone already knows how the reincarnation system works' thought ROB.
''You will be reincarnated in a Naruto Universe, you have 2 wishes, hurry up as I have other souls to fulfill, ah a wish must be used for your appearance'' Spoke ROB while pretending he was signing a document as if cared about the desires of the soul in front of you.
''Well, I want to look like Kokushibou of Kimetsu no Yaiba, I want to know about certain breaths: Wind, Flame, Water, Mist, Moon, Thunder and Stone, also normal breaths, like the one that heals wounds, all in books because I want later if possible, create my own clan'' Said John after thinking for a while, he liked the Samurai, since he goes to the world of Naruto, so he wants to at least know the Breaths of Kimetsu in Yaiba, that way you can be a great swordsman.
He didn't like the idea of using jutsus, he prefers using swords over kunai.
''Very well, you will be sent to Konoha, you will be a baby and be the same age as the main character, I also prepared a little surprise for you.'' Said ROB giving an extremely wide smile, Joker would feel embarrassed in front of the smile of ROB.
With a snap of his fingers, John's soul left the room, leaving ROB alone.
MC POV
my vision was blurry, I'm probably a baby again... BUT WAIT A MINUTE, WHY DO I SEE AS IF I HAVE 6 EYES?
OH MY GOD I FORGOT TO SPECIFY MY APPEARANCE ROB must have given me the look of Kokushibou Oni but I feel like my hands are small, I turned into a mini Kokushibou!
I don't know my surroundings but I started to cry, my life is going to be shit now...I'll probably be with Naruto being treated like a monster.
While crying I felt being held, I stopped crying and looked at the person holding me, he had mushroom hair, wore green clothes and a Jounin vest, he was Might Guy.
''Calm down kid, it's alright'' Said Might Guy as he held me carefully, he started stroking my back to calm me down.
''Guy, did you find something or anyone?'' I heard a voice, I looked to the side and saw a man wearing a mask on his face, he had white hair and he had a Konoha bandanna covering one of his eyes, he was Kakashi, the Copy Ninja Kakashi.
''Only this child, it looks like everyone was killed'' Said Guy seriously, I looked around and saw bodies of dead people, some looked like Shinobi while others wore Yukata and carried katanas.
''Let's take this child to the Hokage, apparently, she's the last survivor of the group, let's also talk about the books we found'' Said Kakashi after he looked at me for a while, then we started to move towards Konoha, which looked like being close, apparently I was part of a caravan that was destroyed.
As I was taken to the Hokage Tower, I started to look around my surroundings, I saw several Shinobi and civilians, some looked at me and talked about me, I understood what they were saying, as I had learned Japanese so I didn't need to use subtitles.
''Look, mom, that baby has 6 eyes!'' shouted a child while pointing at me.
''Oooh~he is so cute! even having 6 eyes!' don't you think Azumi?' A lady spoke while looking at me and holding her daughter's hand.
Finally, we arrived at the Hokage Tower, we were taken to the office, where I found myself face to face with Sarutobi Hiruzen, the 3rd Hokage of Konoha.
I slept after that, I was tired, unfortunately, I couldn't know what my fate would be, I'll probably be a test object or I'll be Danzo's slave.
3rd Pov
''Hokage-Sama, I would like to adopt this boy,'' said Guy as he bowed his head to Hiruzen, while the MC was sleeping, they were talking about the books they got, also about the future of the MC.
Hiruzen said they couldn't let a foreigner live in the Village, even if he was a child, as it was the Village's laws, but they could let it go if someone adopted him.
Guy didn't know why, but he felt a connection to the child, which is why he decided to adopt the child.
Hiruzen nodded and then said, ''Alright, I'll prepare the papers, so what's the kid's name?'' He looked at the MC as he asked about the name.
''Kokushibou, Might Kokushibou'' spoke Guy with a characteristic smile as he looked at the MC, now known as Kokushibou.
''Hokage-Sama, what are we going to do with the books?'' Kakashi asked because the knowledge inside the books was something incredible, the techniques were powerful, whoever created such techniques was a genius, because even an ordinary civilian could be a threat if you learn the ''weakest'' of the techniques that are in the books.
''Let's leave it to young Kokushibou Guy, you'll need to teach this child properly because he'll carry the will of fire, maybe even join the academy'' said Hiruzen while waving his hand like it wasn't anything important, barely he knows that he is being influenced by a divine being because if he were not being influenced, he would probably keep the techniques, as they were quite dangerous.
Kakashi and Guy were surprised but said nothing, Guy nodded and promised that he would show the right way.
They were dismissed from the office and each went to their homes, Guy was taking Kokushibou, he was getting attention because of the child he was carrying, besides having a mark on his face and neck, the child had 6 eyes.
When they got home, Guy left Kokushibou very comfortable in his bed while he thought about what he should buy, he quickly left the house and bought diapers, a bottle, etc.
When he returned, he saw Kokushibou awake, looking around, he put away Kokushibou's needs, then went back to his room and held his newly adopted son.
''Hi young man, I'm Might Guy, your new father, I'll take care of you and train you to use your Youth!'' Guy spoke while shouting the last part, he started to laugh while Kokushibou was with a surprised face.
'So now I'm Might Guy's son...damn' Kokushibou thought in his head.
