Death

This is my first ever time writing anything so I really would appreciate anything help or tips you guys can give me.English is not first language

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

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

So now I'm just floating in darkness with my thoughts in it kinda horrible being stuck with your thought for so long that you start to hallucinate seing stuff that not there so I started counting to pass time but I lost track at the thousands .So I decided to look in my memory in watch all the anime I ever watched again in there over in over in over again.

"Hello there my child "said a heavenly voice "huh who that are you "Michael said freaking out

"Don't worry your fine in I'm what you guy call a rob in I'm here to give you 3wish in a reincarnation because you die before your time"ROB

"In there is any strings attached to that right"Michael

"No you a good kid in I wanted to rewards you for being such a good person your old short life" Rob

"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

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

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

"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

"Ok" Michael "what world I'm going to"

Rob"the demon slayer world I had enough of seeing so many people die of this demon that think he is God I gifted someone with powerful talent to kill him he got very close but failed because that coward decided to flee"

Michael "you talking about Yorichi in also how can I help if get in demon slayer not to chatter your dreams but I'm going to die brutally even if I tried I'm not that strong"

Rob"that where the wish come to play you get 3in they cannot be to broken"

Michael"so for my first wish i want to have the best physique in all of demon slayer history preferably a uzumaki physique.For my second wish I want to have great talent one of the highest talent possible with great potential with it to in 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'm have to remove the mangekyou sharingan because demon slayer is not such a strong world it will be to broken in if give it to at best what I'm make do is remove the demons healing factor while it active"

Michael "I'm fine with all that can I know when I'm gonna be when I'm in demon slayer also how will the sharingan work considering I'll be the only with chakra in a sharingan "

Rob"You going to be 4years older than the main character in I'm gonna drop you off to rengoku family house you going to be adopted by them cause i know he your favorite character you'll just see their life energy that basically 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 chacra 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
