Kagura is a member of the Yorozuya and the main female protagonist of Gintama. She is a member of the Yato Tribe, the daughter of Umibouzu and Koka, and the younger sister of Kamui, one of the main antagonists of the series.

During her childhood Kagura lived in the slums of a faraway planet with her father, mother and older brother. At one point, her older brother injured his right arm through unknown means but he hid it from his and Kagura’s mother but not Kagura. Later on, in her childhood, her older brother Kamui attempted to kill their father Umibouzu, however, he failed and only managed to cut off his father’s arm. This caused Umibouzu to go berserk and he nearly killed Kamui but was stopped by Kagura. Soon after that, Umibouzu left the family. In fear that he might harm her unintentionally just like Kamui, Umibouzu left to avoid destroying his family any further .
