Loud, short-tempered, cranky, and very strict about her duties, Kaoru tends to ramble on and on. However, she has a soft spot for attractive men and action stars. Unfortunately, her favorite action stars always end up dead. She makes a repeat appearance in JFA, again as a security guard. She wears a wedding ring, and in the first game, she made mention of a son. Kaoru claims to have worked in show business in her younger years, but in what capacity isn't entirely certain.
