I can't help but draw Rika. I mean, like, constantly. I can't quite but my finger on it but she's hot as hell, her character's pretty awesome up until she forgets how to say anything that isn't "Chaz...", and she rocks in the battle system as well.
Okay, so I guess that's why right there then.
EDIT: Okay, the assets are a bit crazy but theoretically they match up with the only screenshot you can get of them in game, sooooooooo there's something wrong with me, I know.
