Korsica is described as having a fiery temper, a strong will, and a strict-sense of justice. In comparison to Vandelay's other bigwigs, she's been stated to be the more reasonable and levelheaded of the bunch.
Her attitude is one of skepticism and logic. Though she can typically sense when things are off in her day-to-day work life.
Korsica is a careful planner and decision maker.
Similarly to Peppermint she can be tough and have a short temper, but she has a big heart.
