"Superman: Guardian of Hope"

We all know how this story goes. I've often found myself looking for something like this and never found it, so I decided to create it myself. So here it is: what would happen if a man died and reincarnated in Boku no Hero as a Kryptonian? ~~~~~~~~ NO HAREM~~~~~ English is not my native language, so please be patient with me, and I would appreciate any tips you can give me. * I don't own any characters from the Boku no Hero universe or Superman; I'm writing just for fun. All credits for the characters go to their respective creators. * * My first time writing, so I'm subject to mistakes and the chapters are subject to changes, but without much impact on the story. *
