Kodachi "The Black Rose" Kunou (Age 16) is the sister to Tatewaki Kunou
in the manga
series Ranma 1/2
. Claims herself to be the "The flower of St. Hebereke High School, the rising young star of rhythmic gymnastics
martial-arts". Just goes by the name 'Kodachi', while her brother just goes by 'Kunou
Kodachi is just as wierd, although not nearly the narrow-minded fool her brother is (it must run in the family). She is much more vindictive and vicious in her dealings with others. She is quite a formidable opponent with the gymnastics tools like the ribbon, clubs (with concealed spikes) or hoops. She will not stop there either as she often resorts to assault, ambush and cheating against those who stand in her way.
She has both a deep affection for Ranma-kun and a deep hatred for Onna-Ranma after separate encounters where male-Ranma accidently smacked her with a kettle of hot water on the Tendou rooftop which chasing down p-chan and also when female-Ranma beat her in a gymnastics competition, respectively.
Kodachi has both the trademarks of black roses and an obnoxious laugh.
