Kujo is very passionate about Blue Ship's ultimate goal. She is generally very calm and reserved, but can grow ruthless when the situation gets difficult. In the novel, she is seen to be very shy and somewhat naïve, though this is a façade. She and Maki seem to have a very close relationship, the two almost like family. Though Kujo initially just planned on using Maki, she later comes to care for her and tries to make her understand her point of view.
