She is very independent, no-nonsense, cold and apathetic. She also very honest, by believing everyone especially the "weaklings" will die in next day at their duty to kill klaxosaurs. At some point, she can be childish and a trickster, especially in Episode 8, where she tricked the other Stamen to bathe in the girls bathroom, and stole their clothes. She also has weird habits, like when she poured honey on her food and licked people to feel their "taste".
