Why is there an alt format of this? But, whatever, I actually had some interest back near the start, will see whether it actually was the beginning that was better or not with this alt version.
It's an adaptation. Maybe it will be shown later in this version, but it's an isekai nonetheless, not that it has any influence whatsoever in the development as far as I know (like most isekai nowadays, that does so just for the tag it seems).
