Mmmm..... alright, I think it works. I don't have a very strong feeling one way or another. Things get wrapped up in a .... sort of real life way, apart from spooky dude. We see fleeting glimpses of the characters simply... moving on.
I get a slightly rushed vibe from it, despite 70+ pages, but no real complaints on how it all concluded. A good read overall, and I quite liked Igarashi.
