Cool mystery, scary art, but the characters are frustratingly dumb.
This is definitely the type of manga whose plot is moved forward by characters making bad decisions and arbitrarily withholding information. Like, mix soap opera and horror movie characters together and you get these characters.
They also do this thing where they make a character go 'crazy' or get so distressed that they make REALLY bad decisions. I don't mind if these types of things happen every now and then but it happens often enough here that I get really frustrated with the characters.
Still a fun read, enough suspense to keep me going.
