I'm a librarian who loves anime, manga, and reading a wide variety of genres.
So. This was fucked up.
I figured out parts of it. I correctly guessed the identity of the murderer (more through murder mystery logic than any clues in the text), and I was mostly correct about the murderer's motive. And I expected this club to be a pit of vipers. I just didn't realize quite how bad it was. Dang.
