Hime debuted in Suguri, as the final boss. She is the Guardian God of the colony ship Shifu that controls her. After being forced to fight Suguri, they become friends under a united goal.
Hime and Sumika consider each other sisters, since they were both Guardian Gods of Shifu's spaceship.
Hime refers to Sora as "Sis" in English translations. However, in Japanese, the original term "お姉さま onee-sama" is more commonly used as an affectionate term to refer to a highly respected older girl.
This can be contrasted to Hime's usage of "妹 imouto" for Sumika, a much more impersonal term to refer to a little sister.
