Everything you thought about the harem genre to be destroyed in one manga.

This manga has an exceptionally dark story line that has a mix of mystery together with the story. I would describe this manga as something really 'messed up'.

People breaking down and losing control of their logical thinking and going to extremes to survive. In other words, the story is much like a 'death game' story where everyone will stake everything to survive.

Character developments are well done. The characters change and adapt through the course of the story and have interesting backgrounds. Its a story that keeps you engaged and wanting to know what will happen next and how the characters will continue to change, for better or worse.

So if you're up for an extremely dark and disturbing, psychological manga, then this is for you.
