Imma keep this quick:

You are a normal(ish) human, on a normal earth, living a normal life - until you have been chosen by a mighty powerful being to solving the problems of alternate universes. You are to take the vaunted role of an isekai protagonist!

Fail, and you've doomed the world you were supposed to help, succeed, and sweet ass rewards await you. You game?
