Kaoru is the abjutant master of the Kamiya Dojo in the outskirts of Tokyo. Her mother died when she was little and her father, a member of the Metropolitan police, was killed six months ago. So at the beginning of the story, she was all alone. That is, until she met Kenshin...
Kenshin saved her life from two crazy scheming brothers, Hiruma Goheh & Kiheh, who wanted to kill her and take over the dojo. Afterwards, he was going to leave, but Kaoru told him she didn't care about his past and asked him to stay with her at the dojo.
Kaoru is a strong-willed woman very aware of the changing times. She trains seriously in kenjetsu, forever taking into heart her teachings of "a life that protects life." Although she has to be saved at times, she's actually a very good fighter who won't take any crap from anyone. Too bad she isn't very ladylike, or very good at expressing her feelings for Kenshin. It's okay, Kaoru-dono, he'll figure it out someday...
