She is reserved, shy, and a bit of a klutz. She doesn't know how to cook but that doesn't stop her from trying her best. She has the power to produce wind, she tries to help in any way she can.

Designed to be a general-purpose, if beautiful, tool for Kabapu, Ropponmatsu (Unit 1) excels in bomb-disposal. After failing in her first mission, she is given an additional form (Unit 2), that of a perky, young cat-girl. In the original manga, only one Ropponmatsu unit is active at any one time; the reason for this is later revealed to be that there is only one central "core" that is switched between the two bodies. Kabapu attests that the core contains the soul of the princess of the lost civilization of Solaria, and he has had the Ropponmatsu body created to house it as part of his plan to destroy all remaining traces of Solaria's technology. Conversely, the anime (produced before this revelation occurred in the manga), has the Ropponmatsus appearing as two distinct entities who frequently cooperate on important tasks. Although they have a tendency to be destroyed on their missions, Shiouji keeps a lot of spares, which play a large role in the penultimate episode of the series). The vast difference between the units leads to some tension between Kabapu and Shiouji: both incarnations of Ropponmatsu have a tendency to fail in the course of their duty, due either to extreme mass (Unit 1) or lack of appropriate functionality (Unit 2).
She is introduced in episode 3 as an assistant of sorts to the Female Informant from Episode 2. Much like her predecessor, she demands sex with either Rin or Mimi for information. Although, her first encounter with Mimi was less than romantic, by episode 4, they appear to have entered into some sort of relationship. After episode 4, she has apparently died.
Having faced hardship since childhood, Tomo is sadistic and cruel. His mind is contorted and he is severe with others. It is said he was taken in by dancers when he was young, exposing him to the world of Chinese opera. This fact would explain why he wears a Chinese Opera costume. Tomo is one of Nakago's most trusted allies because he freely discusses his plans with him. (Source: Wikipedia)
The childlike goddesses serve Taiitsukun and reside at Mount Taikyoku with her. They are also known as Lai Lai. They can take the appearance of floating orbs and can appear when commanded. They have healed Miaka and her warriors when it was necessary, also offering to fix Nuriko's perversion (much to his dismay) and Taiitsukun's face (much to her annoyance). Their other function is to serve as vessels for the spirits of the dead Celestial Warriors, so that they can fight along side their priestess, in which case they take on the appearance of whomever they are inhabited by, and have all of their powers.
