This was really fantastic. It's cataloged as a mystery, which I suppose it is, but it isn't really the usual format: In this case you're following along with the people who committed the crimes, and they're certainly not portrayed as villains. I loved Masako's character in particular, but all the characters were incredibly relatable, even the most disturbing or unlikable ones. Excellent story arc and character development, and I have to say, I love how it ended.
