This was really good! Yu's showing slow but steady character growth, Mitsuba wasn't too terribly annoying for being a loud-mouth bossy pants, and there was really good actions scenes. It does bother me that Yu keeps stealing the spotlight, I'd love to see more of the other group members' weapons in action.
I still can't stand the vampires and stand by my opinions on them as villains. Seriously, aside from Mika, are we ever going to meet a vampire that isn't condescending or obnoxiously full of themselves? All of the vampires presented so far have practically the same personality traits which is incredibly annoying. Honestly, if they didn't have such different characters designs, I'd barely be able to tell them apart. I'm going to be really annoyed if Ferid doesn't end dying at any point or if it takes too long to kill him off. I really don't think I can handle this series if I have to put up with him through most of it.
Complaints aside, I'm enjoying this series, good shounen fun.
