Probably my second-least favorite Anime Mirai thing I've seen (though I've only seen one or two from most years and none from the first year). Animation was okay but never really stunning and it had at least one laughable fuckup that I caught (the girls sliding around the stage with no tween frames like 30 seconds from the end).
Mostly it just seemed kind of... lifeless. The music was mediocre (pretty bad considering how central an element it was), the direction was boring, the writer had nothing interesting to say and no unusual way of saying it. The pacing was kind of a trainwreck.
There was no yuri. There was no real relationship and certainly no romance.
Go watch Wasurenagumo, Harmonie, or Little Witch Academia instead. Those don't have yuri either but at least they're good.
