Reincarnated (Reverse Harem/Self Insert)

When I died I thought I would be greeted by God or even the Devil.
But instead I was met with The Creator telling me that I was born in the wrong universe. That they (The Creator) didn't know what my intended reality was supposed to be.

So they gave me a choice.
I could pick a reality I wanted to live in because they didn't know what to do with my soul.
The Creator told me it would be a cool experiment to see how I could change things with the knowledge that I have.
