Her mother died of an illness when she was very young. The previous pets all died because of her own inability to control her strength. 28' was the latest deceased addition in the form of a dung beetle. She typically wears a red cheongsam with yellow piping.
Knowing her brother and father weren't around, she traveled to Earth to start a new life. Her hair is tied in two knots to the sides of her head and are covered with ornaments.
She loves eating and seems to have an insatiable appetite, with a particular fondness for rice and sukonbu.
She seems to have strong 'maternal instincts' as seen in various parts of the anime, like when she wanted to breast feed "Gin's" child in Episode 51.
When she recieves a confession from a boy, Shinpachi remarks that going by just looks she's a beauty.
Kagura can be described as naive to a fault as seen in her introduction where she was tricked by a gang into thinking that she was protecting them when she fought their rival gang.
While at home, Kagura was left with taking care of her sick mother and she would wait for Umibouzu to come back from his alien hunting work.
