Personally, I'm disappointed on how this turned out.
I love the Deader Arc and the four antagonist really have very good characterization, but I felt like Mikazuchi's change of heart was so out of his character. He was introduced as someone who is rational and is stone-cold towards half-fractured humans that he even instilled to Jagasaki and the other members of his team to not treat half-humans as humans. But then he got fooled and swayed by one, and turned his back against the team that he nurtured. It was a very disappointing decision, seeing how he had a constant philosophy until he saw his son "revived" by the leader of DDL. His form of justice turned to shit at a snap without even doubting Nomen's capabilities in reviving a person. He lost his perspective so quickly that I even felt anger towards such a fictional character!
Mikazuchi has been my top favorite character in the series until this happened, so it's going to be hard for me to continue on with the next volume since I'm not feeling it. Also, where the hell is Chiharu in such a massive event like this? Will we still see him in this story's further development? Only one way to find out.
