All of this starts with the protagonist getting an ability. I was ecstatic after getting superpowers, but I also had to accept new settings and stories. It may be that the protagonist is short-sighted and unable to accept so many strange settings at first, but his ability to accept it becomes stronger day by day, so he has no choice but to accept this setting. He's just a fool anyway, so there shouldn't be any big problems. Etc! Wait! The next step is a big problem...
Concept: Nonsensical but can be interesting
