This manga is all about mystery, gore, unexpected twists and really unconventional characters. It also amazing the level of crazyness: the look of the mahou shoujos, their creative way of killing, how the characters develop...The comic relief always comes from the least expected person. The plot itself is also pretty confusing and has some plenty of (at least for me) "i totally didnt see this coming" moments. So yeah, its hard to get bored with this manga.
So far, I've read all currently available 39 chapters and it seems from explaining everything, and its still very enjoyable.
