Nothing Like A Bit of Love

Kasey Jones. No, not the boy. In fact, it's his identical twin sister, who prefers to go by Kase, Kas, or K. Kasey's best friend Okamī Saki moves from Japan to New York, and the two run into the turtles after they follow her brother down into the sewers. Kasey is hyperactive, not-to-mention a complete and total geek for anything, like Mikey. Okamī is a hothead who, unlike Raphael, would gladly admit (because she's a woman and therefore, more empathetic) that she would die for her friends and family (given that they aren't psychotic murderers. Oh wait, her dad is).
