She's usually taciturn, but the type to go wild once a battle starts. Also, like the artist Yoshihide from the original work, she is an extreme aesthetician, but she finds beauty in battle. She pursues an artistic philosophy called "Mandanjee" and shows a twisted sense of aesthetics, finding beauty in gore and grotesque, snuff-like elements, such as saying people look better when shortened. Besides this, she has a personality that enjoys irregular situations, often suggesting a battle royale whenever opinions are divided and getting excited by herself upon seeing a chaotic Warp Train. Conversely, she shows a distaste for things that are smooth or business-like. When she scowls, her eyes are highlighted in red. It's later revealed in Chapter 9 that these are combat-assisting ocular implants, colored to match her biological mother's eyes. However, given that she had red eyes as a baby and they glowed red when she was serious even before the surgery, it seems she was born with red eyes. On the other hand, she shows a surprisingly comedic side, making puns with her own name and then bursting into laughter right after. She also has a very peculiar way of speaking, using abbreviations at every opportunity, which no one can understand. Despite her eccentric personality, she doesn't show a cold or cruel side in situations unrelated to combat. She has a fundamentally cool personality, secretly cares for her comrades, and isn't without her human side, sometimes teasing people she likes. She is a heavy smoker. She always has a cigarette in her mouth and is said to always smoke one after killing someone.
