The other half of City Hunter, and Ryo Saeba's partner. She is primarily responsible for getting clients, and other managerial tasks. She also cooks and defends Ryo's female clients from his less honorable intentions. Though Kaori's combat skills don't even come close to her partner's, she can stop Ryo cold with one of her hammerspace weapons. Primarily she uses a hammer (usually weighing at least 100 tons), but she uses other objects as well. She also learned how to set traps and plant explosives from Umibozu. Her shooting skills are affected somewhat by Ryo's tampering wiith her gun, meant to ensure that she would always miss and therefore not be able to bloody her hands as Ryo has had to do.
