This manga wasn't axed, it was started to be short, it was only a adaptation to catch readers interest so they would go to the novel to know the rest, and I think it worked.
They knew that this story drawn from this rtist would work, as simple as that.
Unfortunately the chances it gets rebooted are null, and to add to that it could be from someone with far less skills, so is probably better to leave with a good memory than seeing it drawn from a unskilled newbie.
Maybe, maybe it could get a anime one day, as the isekai boom finally quited down and the anime industry is starting to animate interesting works again.
