This book is a good mix of slice of life, thriller and science fiction. Think of things like the shows LOST, Twin Peaks, or anything else with a somewhat geographically limited yet full of supernatural mystery type of narrative that’s not fully divorced from reality. If anything, toward the end of this initial volume some things get a little messy and confusing but I think that’s intentional as it’s a volume 1 and there’s at least 6 volumes already available in English (2 in 1 compared to the original Japanese volumes) if you get intrigued by the series. It will all mostly be explained as it progresses hopefully.
