This volume is a volume that specifies universe ghouls, its ins and outcomes and the presence of the enemy ghouls. The universe is set up and becomes increasingly complex and dense and above all it really comes to life. Indeed it is not limited only to the fighting, there is much more to learn and I am more and more convinced.
However there is the presence of some stereotypical characters, the agent that kills without real discernment revenge taste will tell us, the ghoul who gives free rein to his instincts. This also helps to show that everything is not linear, the main characters are all very nuanced and bring a real interest in the series.
A second volume a bit less breathless as the first but makes addicted to this series that I follow with pleasure.
