On first glance, the story is indeed a combination of AnoHana and Sword Art Online, though at a downgraded premise of both shows.
I love Lerche's animation coming that I've repeatedly watched Assassination Classroom and parts of Classroom of the Elite but this anime doesn't give me that kind of enjoyment.
Also, for the music producer's fault, I hear this kind of background sounds on parades. Seriously, Always.
Well, as I've only seen the seven episodes this time, I look forward to any twists in the story that would rather make it amusing. If not, then, I'd pray that there will never be a 2nd season adaptation to be announced in the near future.
