Yeah I think a different group picked this up. They update on Mangadex but not here. Man I miss Mangadex comments. I wish they'd add them back already. Anyway, I'm enjoying this but it definitely feels like yuri is not the primary plot motivator, which is probably why some people are put off. Urasekai Picnic is the same way, where it's a mystery and horror story first and a yuri romance second.
For me, the problem was never that romance wasn't the focus. I think, since you mentioned otherside picnic already, the difference between these two is:
Otherside picnic has fantastic pacing. They never dwell on things too much, thus there's suspense (although of course different from an isekai action manga) that never disappears.
On the other hand there's this, where it doesn't seem like it knows what it wants to be. I mean, to be fair, the translation for the web novel is an absolute trainwreck and this follows the light novel - which I haven't read - anyway, but even there I realize that the author tries a lot to make the worldbuilding and magic work. This seemed to be the same at first with this manga, until they drifted off to try to be an action manga, without having the base to be one.
