Tae Shimura is Shinpachi's older sister. She runs the Kakidōkan Dojo, which was her father's failing dojo, with her brother.
Despite her sweet face, she is one of the most violent characters in Gintama (and arguably strong too). She often displays her trademark sweet-looking smile with her eyes closed before engaging in her violent activities(~.~). Her killer intent is so strong that on one occasion, a stare from her brings the entire Shinsengumi on their knees begging for mercy. Her weapon of choice seems to be a naginata, a Japanese spear.
