PIcked this as a recommendation as one of the "Must read Mangas" from the 2010s
This was an interesting concept but this volume was overall extremely repetitive and formulaic. There is an underlying mystery to the story but its really not explored. Also, this story has not aged well at all reading this in 2020. At face value, it is very comedic in tone but when the school starts pulling in extremely disturbed students to assist in assasinating the alien teacher, it hits way to close to home given recent headlines with violence in schools.

Strong start and finish but the middle was a bit to muddle through. Overall I think there are some good ideas presented in the novel but held back by the YA age range. I really was getting into the concept of the Reveries and the lore but then it pulls back on it to focus on interpersonal drama and romance. The ending felt a bit rushed but was still did a good job without leaving too many loose ends. Its a good story for anyone wanting a Scifi YA book but other than that it really doesn't bring anything new to the table.
