Yuri or nay?
Signs seem to be pointing to the former. There's a point of contention since there's a version published in Yuri Hime S (titled Konohanatei Kitan) and a continuation/reboot running in Comic Birz, but the anime seems to be taking the story from the Yuri Hime version.
What people see as subtext is true for the Yuri Hime version.
Well, it's as gay as the gayers Kirara show.
Also, it's not a reboot as far as I know, but a sequel. Comic Birz even published the Yuri Hime chapters.
