Theoretically, Kaede never even existed, as she's merely one of the personalities of one Garcian Smith. But Kaede takes the cake when it comes to sheer atrocity. She's the loveliest of Garcian's personalities, wearing a bloodstained white dress and slitting her own wrists to shower Heaven Smiles with blood. How much more interesting could a fictional assassin get? She's not without her apparent sympathetic side, with her trademark "hurts, doesn't it?" line upon a successful critical shot, but we wouldn't want to catch Kaede on a bad day.
