Kurisu is generally a sensible, serious mature young woman, usually calm and collected even when someone is acting tense in front of her. However, she can also show a much more timid side at times. She is shown frequently to hate being nicknamed, as she dislikes all of the names that Okabe gives her, with 'The Zombie' bugging her most of all. Ironically, Kurisu is also practical and a realist she believes that time machines are works of fiction only.
