Urozakuro

Urozakuro's physical manifestation resembles a seductive woman with her eyes masked by a black leather belt. According to Sajou's remarks, "Her face, coincidentally, resembles her sister's quite unnecessarily."

She is the very opposite of Sajou, being a buoyant and verbose person, and has a preference for the "unnecessary" things that Sajou talks about.

She interacts with Sajou almost mockingly about everything, although Sajou pays her no mind. Her behavior seems to relish moments of his crisis, enjoying "the thrill of the owner sensing danger," which is why she had revealed her powers to Urahara and Yoruichi shortly after they began prototyping the transference bodies.

Furthermore, because Urozakuro's mental world merges with the real world due to her abilities, she can exist outside of the mental realm, yet when she is conversing with Sajou, she is not perceived by others, making Sajou appear as though he is talking to himself.

Additionally, the mental world she inhabits is used by Sajou as a dumping ground for emotions he deems "unnecessary."
