Recently when I began playing Guilty Gear Isuka, the only character I had any real affection for was Baiken... but the moment I saw (and heard) I-no in action, that changed. I-no is sex, drugs and rock-and-roll, and her heavenly bedroom voice is a nice distraction from her beating the hell out of the poor sap she's fighting with her selection of aerial and ranged attacks. Her backstory is basically nonexistant, but she seems to be a Rockstar, a witch, and more than a little bit of an exhibitionist, and generally a hedonist, living her life to do anything and everything "fun." >:D Her movements are sensual and the way she swings her "axe" so aggressively is flat out hot... not sure I'd want to be on the recieving end of THAT kind of fun, but yeah... she's definitely a true lust.
