Hachi has a feminine appearance. She has long, black hair that is tied at the end and a white complexion. She has two dots on her forehead and cheeks and has semi-closed eyes, similar to Chinese makeup. She wears a simple white kimono. Her true appearance is a girl with a light skin complexion and messy, short brown hair.
At first Hachi comes of as a motherly like figure, but like the other Admins is just as coldblooded and vicious as them as she didn't flinch at killing Magical Girls in mass and wasn't above mocking Sayuki Ringa in battle and overwhelming her unfairly a hundred to one in their battle in order to corner her. She also is shown to have a preference in launching surprise attacks on her targets as seen with the swimmer magical girl, Asahi Takiguchi and Sayuki Ringa in order to kill them faster, rather than have a dragged out fight with them.
Hachi can create a seemingly infinite amount of copies/clones of herself in an instant. Her clones possess the same powers and strengths she has and seemingly doesn't deplete in number this indicating that they can also copy/clone themselves, making her an instant army of clones. However the weakness to this power is the fact that Hachi still has one true body hidden among the clones, and if destroyed it will kill her for good.
