I have so many favorites...
Definitely, Shizu - Kurumi was right that you want to hate her but can't help liking her
I always liked Kanna - farmer and warrior always makes for a legendary combo; also, she's the only one who was able to beat Hikaru and the gang in Book 1.
Yue-fang always reminded me of Kanna for some reason... do they use the same voice?
Sorana... I aways felt bad for her - living as a clone and all.
Shizu's mother - I always liked that story arc though I admit I thought it would turn out differently... I thought she'd end up sacrificing her life for Shizu.
Johan! A more lovable down-to-earth and somewhat foolish version of Robin Hood. He becomes like indestructible by my second play through.
Bah, too many! Maybe, it's easier just to say the ones I love to hate!
Sypha! She irks me off for some reason... I always thought it's ironic how everyone in Book 6 say what a fool Nekurow is because of his whole obsession for vengeance, but Sypha isn't any different if not worse. Granted she has a reason to want to kill Nekurow's ancestors, but she exacts her revenge on their descendants who are ignorant as hell, and the vengeance for getting kicked out is more of an issue of pride...
I thought Kasumi and Book 3 was hilarious, but Kevin's a bit annoying. I think it's because in Book 3, Kasumi just seemed dense and like an idiot who doesn't know what the hell is going on around her, but Kevin knows too much and still acts like an idiot.
Oh, yeah, I always like to hate Arcadia too. She was a good villain.
Zule... I wouldn't trust him even if he passed a lie detector test... I always thought it was funny how Shizu's group is all in sync under her command, but the four sword guys are just a
very loose confederation: Nekurow's goal is obvious and personal, Zule's - is personal but I don't really know what it is but you know he's gonna screw
anyone over to get it. Six can probably be trusted but I remember he says that he doesn't care about getting vengeance anymore, but when he destroys something, you can tell he was lying by the things he says, but they defeated the Jin so who knows; and Hikaru is just as or more than likely to help Shizu than to fight against her, so you already know that he and Nekurow are going to butt heads somewhere along the line...
