I think this may be the first book where I can honestly say I gave me more questions than answers, and it's all thanks to those flashbacks. How did Worrick lose his eye? Was it Nic? If so, why would he hurt him, considering he's never shown any displays of ill will towards the kid? How did the two get to Ergastalum? Where's Worrick's mother, and how did she survive? Why do present day Nic and Worrick have such weird and cryptic dialogue? We may never know, but I hope that's not the case.
Other than the flashbacks, this volume is pretty good. I still adore the art style, though Kohske has a little trouble with side profiles at times. The action is amazing as always, as is how the volume deals with darker subject matter. I like the how the relationships are developing between the three main characters, especially Nic and Alex. We meet the head of the Christiano family, Loretta, and she is probably one of my favorite characters, though we don't see much of her this volume.
Can't wait to read the next one!
