Martijn OMG’s review published on Letterboxd :
An international school in Kobe Japan goes into a timeslip and is transported to a post apocalyptic earth (only mentioned very brief). This is one strange movie which isn't weird since this is from the same director that gave us Hausu. It's an manga adaptation and sadly it isn't very good. Lots of questional acting and some very bad fonetic English but also some WTF moments to keep you interested. The main music theme by Joe Hisaishi is great.
