The line drawing Sui Ishida is fine and well restores the action and history, everything is in perfect fit. We have not dealing with a novice designer with caricatured features.
When it comes to the history of a first volume so there was a set up and it becomes more complex to progressively and most questions we ask, the ghouls are they really the monsters we believe. Our hero is an "anomaly" will allow us dexplorer their world and discover more about them.
In summary a manga that i devoured and I would read following with great pleasure, I recommend it.
