I was hoping this arc would be coming to a close, but it looks like its going to keep going for quite a few more chapters. Sadly, I've come to the conclusion that I just don't like this series anymore. I enjoy romantic comedies and don't mind a light bit of action here and there. But with this turning into a full blown dark action series complete with drawn out battles and boss fights, I've unfortunately lost interest. Very few shounen action series do anything for me and that's what this has shifted into. I can take action in small doses (like Be'elzebub), but overall, just not my thing.
Maybe I'll come back to read it when it's over, but as it is now, I no longer enjoy it.
