She has a kind and caring nature, that extends to her job as Anti-Skill, and is most especially apparent with children, which she has promised to herself never to turn a weapon on them. However, her love more or less encompasses violence that an old generation P.E. teacher like her will execute.Due to her habit of ramming delinquents with protective items like shield or helmets to resolve incidents, saying it's alright to do so since those are protective items, she's known as 'the woman who uses comedy-like methods to solve problems that could end up as a tragedy'. Out of the job, she is very cheerful, and enjoys beer, eatouts, and public baths with her friends, apparently, willing to go become pass-out drunk in public. She also believes that there is no shame in showing her naked body to teenagers like Accelerator since they are still children. She also has a tendency of going on a cleaning spree when upset which ends up in making her do reckless things like losing her keys She has a tendency to end her sentences with "-jan" as a verbal tic.

Besides being 30 years ahead of the world technologically, more than three-fourths of this peculiar city's population consists of students developing their psychic abilities as espers in various institutions. Among these students is Touma Kamijou, a high school boy with the lowest psychic rank of zero, but with a mysterious power no scientist can understand: "Imagine Breaker," which allows him to negate other supernatural abilities. This, however, doesn't affect Kamijou's life in the least as he plays his role as a regular teenager; that is, until he meets the strange Index Librorum Prohibitorum, a young girl who has memorized the entire forbidden grimoires, and now a dangerous organization is hunting Index down. With several magicians looking to harm the girl, Kamijou will defend his new companion at all costs as he discovers a strange new realm of the supernatural.
