princess kakyuu is a very important, yet short-lived character. she is only in a small number of episodes, because she kinda gets killed. the sailorstarlights, her gaurdian senshi from the planet kinmouku, spend a great deal of time and energy trying to find her. she finally appears to them, but alas, she is soon killed. it happens two different ways. in the anime, she is killed by sailorgalaxia. in the manga, the story is very, VERY complicated. there are two very violent mambers of the animamates: sailors chi and phi. kakyuu kills one of them, the other kills kayuu, and sailormoon kills her. eh, it's really complicated. i'm not quite sure as to how it really works.

barely any specific character information is given for kakyuu. no specific birthday, no specific blood type, no specific favorite food, basically no profile-type information. all that is known about kakyuu is who she is, where she's from, and what she does in the show.

kakyuu is pretty close to chibi chibi. as to why, i'm unsure.
