So, we've finally got our title character? About time.

And of course the new story arc starts off fairly dark.
I like this Purple Knight guy* though. He comes off as pretty unconcerned/amused with the whole prison situation. I'd guess either the old man has already seen it all or he has a plan.

*First impression is someone out of One Piece. Some mix of Garp and a less (obviously) evil Blackbeard.
