Rebirth and Wishes
In the void there was a ball of light that was floating there for an unknown amount of time. Suddenly the void began to crack and from within those cracks an old man began to appear. The little ball of light began to expand until it took a humanoid figure. The old man looked at the figure and he began to speak.
Old man: Hello young one before you ask you are dead.
?? : I'm dead? How come I don't remember that I died?
Old man: That's because I killed you by accident when I was inspecting your world so I'll say this once I am sorry.
?? : What?! YOU DON'T EVEN SOUND SORRY AT ALL?!
Old man: Well calm down now as compensation I will reincarnate you in another world with 5 wishes within reason but keep in mind that you can't return to your original world.
?? : Wait. Why is it within reason. Why can't I just wish for anything I want.
Old man: [sigh] If I let you make a wish that's too powerful for your new world you will break the balance and that will inevitably destroy the world and if you become the strongest within a year you will have no more challenges and will end up bored and depressed.
?? : So basically I will end up as Saitama from one punch man hey can I choose a wish that will become op if I train it to the max and if I can could I start.
Old man: That depends on the wish and how long it takes to become op because to be honest I will be watching your life for some entertainment and I will be bored if you end every fight with one hit anyways you can start.
?? : Ok that seems reasonable so I'm gonna choose my world first the world I want to go to is High school DxD I don't care what family I get reborn into but make me be born into a family that has knowledge of the super natural world but I want to be the last of the family and make it a rich one I don't want to be poor and make me handsome.
Old man: That can be done what are your wishes.
?? : For my first wish I want a sharingan that will evolve with enough power and that won't go blind.
Old man: That can be done but to replace the blindness the pain from over using the eyes will be 2 times worse. And your Sharingan will be activated at Middle class but you won't get all the tomoes till High class, Mangekyō Sharingan will be unlocked at Ultimate class but yours will directly turn into EMS and Susan no will be unlocked at Mid Ultimate class.
?? : Thats ok for my second wish I want to have the wood release Kekkei Genkai.
Old man: That can be done.
?? : That's all good for my third I want to have a natural affinity to lightning, wind, water and fire and countless scrolls that has every technique in the Narutoverse.
Old man : Hmmm also can be done and to make it more practical I'll make you descend from a family of Shinobis.
?? : For my forth wish I want be able to use Senjutsu from DxD like touki the ability to create my own sage mode.
Old man: Hmmm why not fine but to create your own sage mode will be extremely difficult.
?? : That's fine well for my final wish I want to be the protagonist and I want a girl to be the holder of the boosted gear.
Old man: That's a tough one okay but in exchange you will have to join Rias Gremory's peerage.
?? : That was the plan but now that I think about it who are you.
Old man: Hahaha that is a secret but I'm sure you know I'm a God by now but which one is a surprise that you'll find out some other time.
?? : Thats fine I was just curious so when will I be reborn.
Old man: You will be reborn now.
All of a sudden a black hole appeared out of nowhere and absorbed the figure and then it closed. The old man looked at where the figure was and created a crystal ball out of nowhere that showed him a little boy.
Old man: It's been awhile since I been to that world I hope he is okay or I'll have to make another "accident" again for more entertainment.
Then the old man just made a throne and he kept watching the ball.
