Welcome to the Multiverse (Dropped)

I died protecting the people I cared about, friends in one life, my family in my second, but surprisingly I get a third shot at life once more with both my past lives merged into my present one. I was John McDouglas I was Mandricardo Now I get to live my life however I wish from now on, and with my own personal System and access to any world I want, I’ll enjoy it to my fullest, be a good guy (probably) or a bad guy (maybe) the World(s) is my Oyster. I have no editor so if there are spelling mistakes they happen alright, also I don’t need people pointing out to me to use the different types of there’s or yours, it doesn’t matter so long as you get what I’m talking about. It’ll start off in KonoSuba and I’ll take feedback from the fans of this story as to where I should go next with it. MC will neither be always good or always bad, he will do whatever he wants so long as he finds it intresting, so don’t get mad when he’s a good guy in one world and a villain in the next, he has free rein to do whatever he wants. I don’t own any of the characters from their respective stories they belong to their respective authors.
