So that's our introduction, huh? I don't mind to do a time skipping dive into events later in the story, to see what the story will be about. This kind of introduction happened in other stories, too. (e.g.
Tanaka, the wizard) Together with the summery we get a picture of what it will be.
But I don't like the MC. Background: A "god" kills him be mistake and reincarnates him with a free wish. That's as generic as it gets. He wishes to be the strongest of that other world. So his OP is to be the Saitama of that reality. And then he decides to wear a kimono in a medieval European fantasy setting? Is this again a story about how superior Japanese culture is and how every asian dish he cooks up is yummy without a single fail? Let me guess. He has to protect his family/friends, which doubles as this stories harem. Oh, brother. We're out of honey.
