It starts off with a very interesting perspective psychology and mental illness..........a murder mystery theme with the writer(s) keeping the viewer guessing at each turn and succeeding in confusing A LOT of people (as evident by many of the comment sections under each episode on various site).
However, I honestly wished they continued with the psychology (for example, if the main character had paranoid schizophrenia or dissociative identity disorder) but sadly, they don't. All we get is a rushed, stereotypical storyline with a farcical plot. I was very disappointed with how it turned out.
I would still recommend this to all anime watchers..........the first half of it especially
