The character dyamic and story cohesion start good and degrade from there, eventually becoming a classic annoying harem travel story. It has a nicely overpowered antihero, though, and as an enjoyer of power fantasy I completely approve of at least that part. I reccomend watching this if you are willing to put up with the "isekai trash" and like power fantasies, but if you need a complex plot and hate harems then you might not like it as much.
