Structurally and narratively interesting.
4 stars
One of the things I most appreciated is that this story is structured in a manner as to be multiple stories that all connect, so it feels like you're reading multiple short stories that initially appear mostly disconnected until too many connections keep making you (like the audience stand-in Kawaji) think that there's something more.
Some of the cases, however, don't seem possible to solve on your own with any of the information provided. A couple of them feel like there is foreshadowing, but others feel like there's just... no way to solve it using the information provided.
