Chiba
Chiba is a dream therapist. She is a determined professional, and her conversations mostly evolves around work, while her feelings are rarely portrayed. She rarely shows any response or trace of feeling, even at a flattering complement by Osanai. She is often frowning, and has a stern attitude. She is straight forward and critical. Her strict personality is expressed through the costumes, which is usually the black and white doctor’s gown.

Paprika.
Paprika is Chiba’s alter-ego in the dream world. Contrary to Chiba, she is lively and expressive of her feelings. While treating Detective Toshimi, she works through talking to him about his dreams at a personal level. This is contrary to Chiba, who is ignorant of personal issues that come up during conversations. Paprika shows an eager attitude to help her patients by showing affection. This personality is expressed through her colourful costumes, usually the contrasting colours of red and green.
