Not really? I haven’t watched the anime, but in the VN’s without spoiling anything every death is suspicious. The police rule some as suicides, but are they? You have to play/watch a playthrough to find out. I ain’t spoiling the mystery for ya. I am currently near the end of CH 7 of 8, even I don’t know all the solutions to the mysteries. Granted I know more than anyone who hasn’t gotten this far yet.
