Hitomi Kisugi

Hitomi is the main protagonist of the series. Second daughter of Michael Heinz, Hitomi is usually the one who actually commits the heists, and is hence uniquely referred to as the Cat's Eye. Hitomi is a very kind-hearted, caring, charming, and loyal woman. She cares deeply about her sisters and Toshio, but her temper often gets the better of her and leads her to lash out at people close to her (most notably Toshio--the two of them get into arguments frequently). She apologizes for what she did or said later on, however.

Like Rui, she is an accomplished athlete and well versed in a number of disciplines and skills ranging from horseback riding to safe cracking. She is a skilled gymnast and is able to perform complex acrobatic moves with ease and grace. She is able to escape most restraints and handcuffs with minimal effort, and it is inferred that she is ambidextrous as well as double jointed. She is a skilled martial artist with proficiency in a number of disciplines, most notably judo, boxing and karate, and also has degrees in kendo and aikido. Like Rui, Hitomi is also able to disguise her appearance effortlessly and can speak several other languages.
