A very good manga,that in a few chapters is capable to create an unique atmosphere and a whole story that will make you enjoy it to the very last chapter,the darkest of the story is similar to the way that kira (death note) try to make the rubbish of the world out, but this time is a little bit different of death note, because here the "rubbish" of the criminals that lives in Tokio participate in a game called by the name of the manga. The game consist in a few series of targets that the players have to finish him by obtaining their marks(everything isallowed, even violence) that triggers a whole of situations where the violent main characters will enjoy it at the very last blood drop of their victims.

A good manga the only worst thing is that is too short :( .
