Hi, my name is Michael, and I die not too long ago by getting hit by a bus. It was a normal day after school that I decided to go buy some food like cereal and milk because we were running out, so after I cleaned the dishes, I decided to go buy some. I looked left and looked right there was no car In it was a red light so I decided to cross.....

I got hit by a bus while crossing the road how can that happen I didn't see it, I looked everywhere but there was no bus, the street was empty.

So now I'm just floating in darkness with my thoughts, it kinda horrible being stuck with your thought for so long that you start to hallucinate, seeing stuff that is not there, so I started counting to pass time but I lost track at the thousands. So I decided to look in my memory and watch all the anime I ever watched again in there over and over again.
"Hello there my child, "said a heavenly voice "huh who are you, "Michael said freaking out
"Don't worry your fine, and I'm what you guys call a rob in I'm here to give you 3wish in reincarnation because you die before your time" ROB said
"There are no  strings attached to that right"Michael said

"No, you are a good kid, and I wanted to reward you for being such a good person in your old short life" Rob said

"Me a good a person, I just have a good mind in try not to be overly rude or aggressive, but first are my parents ok," Michael said

"They are fine trust me they mourned your death for a while but they were able to recover it after 6 years, they miss you," Rob said

"Can I go back to them or at least help them in some way "Michael said

"I'm sorry, I can't my child I'm sorry but I can tell you they live the rest of their life happy"Rob said
"Ok" Michael "what world I'm going to," he said sounding defeated

Rob"the demon slayer world, I had enough of seeing so many people die of this demon that thinks he is God I gifted someone with powerful talent to kill him he got very close but failed because that coward decided to flee, "Rob said (A/N by coward he means muzan not Yoriichi)
Michael "you talking about Yoriichi, also how can I help, if get in demon slayer, not to shatter your dreams but I'm going to die brutally even if I tried, I'm not that strong"

Rob"that's where the wish come to play you get 3 and  they cannot be too broken"
Michael"so for my first wish I want to have the best physique in all of demon slayer history preferably an Uzumaki physique. For my second wish, I want to have great talent one of the highest talents possible with great potential with it too for my last wish I want to be Uchiha without the curse of hatred ."

Rob"Your first wish is easy, I can do that, your second wish can also be done but for your third wish, I have to remove the mangekyou Sharingan because demon slayer is not such a strong world it will be too broken in if I give it to you at best what I'm going to do is remove the demons healing factor while it active"(A/N this talking about the ms ability if he get one)

Michael "I'm fine with all that, can I know when I'm gonna drop off when I'm in demon slayer world, also how well does the Sharingan work considering I'll be the only one with chakra in a Sharingan "

Rob"You going to be 4 years older than the main character, and I'm gonna drop you off at the Rengoku  family house, you going to be adopted by them cause I know he's your  favorite character, in for the Sharingan you'll just see their life energy that chakra  in you will learn new Jutsu with something special that I'm going to add for you"

Michael "So if I train hard enough I can save him. "

Rob"you will have chakra so that depends on you, my child"
Michael "thank you very much this is very good for me"

Rob" goodbye my child, in have a wonderful life"

I felt like I was getting swallowed by something, as quickly grew tired in felt unconscious
