She is also known to always wear shorts under every skirt and dress she wears.
She is considered a 'proper lady' but in reality, she's short-tempered, prideful, and has an improper attitude with some slight tomboyish tendencies and insecurities, a fact few people know of. Despite this, she is generally friendly and easygoing, and Saten Ruiko and Uiharu Kazari comment on how they are shocked to find that, compared to other Level 5's, she doesn't look down on lower-level espers at all. This is probably because she was originally a level 1 esper and became a Level 5 esper through very hard work.

To add to this childishness, she has an inclination towards cute things, most specifically, Gekota and Kill Bear merchandise. She likes frog merchandise, but only if it features Gekota. She has a very irrational and unexplained fear of bugs. She can also be slightly hypocritical at times, getting angry at Touma for not calling her by her name despite never once calling him by his. She often prefers to be solitary and dislikes the idea of being restricted by rules and duties such of those of Judgement and Anti-Skill. She wishes to avoid endangering other people and relies on her powers to try to solve problems on her own, frequently despite her better judgement.
She has a keen sense of justice, demonstrated by her frequent involvement in the crime-fighting body, Judgment, and her resolve is unshakable as shown when she was willing to lose in a fight against Accelerator on the first move to prove the Sisters Project wrong and save her remaining 9969 clone sisters.
