You cannot defeat me because you are crippled by your own definitions of gender
Yagyuu Kyuubei

Yagyuu Kyuubei (柳生 九兵衛) is the sole heir(ess) to the Yagyuu family name, being the daughter of Yagyuu Koshinori and granddaughter of Yagyuu Binbokusai. She is brought up as a male, following the code of a samurai. She is the main antagonist of the Yagyu Arc.


After Yagyuu Koshinori's wife died giving birth to Kyuubei, he never remarried and decided to raise Kyuubei as a male, to be the proper heir to Yagyuu family.

During her childhood, she became friends with Shimura Tae and her brother. During her time with Tae, she admired her strong yet feminine personality. When the debt collectors tried to harm Tae and her brother, Kyuubei tried to rescue them, though it cost her her left eye. From then on, Tae pledged to be her left eye. Kyuubei then left to train herself to be strong, using Tae as her inspiration.


  • Height = 157 cm (5' 2") ; 165 cm (5' 5") (with sandals)
  • Weight = 45 kg

Kyuubei dresses as a man. She has black hair in a ponytail and dark-brown eyes, with an eyepatch covering her left eye. Her weapon of choice is usually a sword. When dressing as a female, she is very attractive; complete with twin ponytails and an orange flower covering her left eye. She wears a pink kimono with short skirt and black socks covering up to her thighs.She also has large breast despite most of time being covered up, in episode 217 Hasegawa Taizo and Gintoki made remark about her breat being large when she was in swimwears


Kyuubei has a bit of a cold personality, probably due to how she trained herself to become strong. However, Tae's influence is currently shaping a more softer Kyuubei, as they share more time together during their free time. She is deeply in love with Tae, and once tried to marry her. Kyuubei tends to act masculine as she was more or less raised as a boy. She also doesn't like it when men touch her, having the automatic reflex of throwing them over her shoulder whether she likes it or not.She also wishes to be a man, secretly wanting to add a man organ to her body or have plastic surgery. Due to her friendship with Toujou and Tae, she doesn't. Due to Gintoki, Kyuubei started to behave like a woman and also he is the only guy she actually blushes or get nervous to when he touches her. She has also occationally shown a lack of common sense and make comments that are nonesensical in very serious manner, such as saying her power level should be mentioned in "P***ses"in Ryuguu arc.
