Naoto

A well-known detective, Naoto was dubbed the "Detective Prince" by the media. She is first mentioned when the department which Ryotaro Dojima works has no lead upon their investigations for the bizarre murder case, resulting in Dojima's superiors employing Naoto to assist them, an action which greatly disturbs Dojima. Furthermore, Naoto claims that the only reward she wants for solving the case is the truth, and wants no assistance from other departments, further annoying Dojima.

Naoto is the shortest member of the Investigation Team. She is androgynous in appearance with short blue hair and blue eyes. She wears Yasogami High's gakuran, with the exception of one optional occasion in which she wears a seifuku-style school uniform. Naoto is often seen wearing formal clothing such as blue shirts, ties and her trademark blue cap.

In Persona Record: Magi Arena, Naoto is seen with much longer, nearly waist-length hair. Her trademark cap is absent and she wears a gray suit with a white shirt and a blue tie.

Naoto is very intelligent and analytical. A running gag, however, is that she texts in all caps with abbreviations.

Due to her desires to be seen as an ideal detective juxtaposed with her age and her gender, she has become quite insecure: she yearns to be seen as an adult, and expresses frustration at being treated like a child by the police force. She hates being looked down upon, and fears no one will take her seriously as a female in a sexist occupation field. The sexism Naoto has tolerated and endured had made her self-conscious in regards to her femininity and trying to balance it with image of an ideal detective. In response, Naoto disguised herself as a male from an age young enough to be able to fool most people around her, including wearing platform shoes. It is also implied Naoto began binding her chest to hide her breasts.

When she confronts her Shadow, she comes to the realization that her true desire is not in becoming an adult or a male, but to be respected for who she is as a person, including accepting herself as is. However, years of disguising herself as male along with her own personality quirks have her struggle with trying to embrace her femininity after denying it as a part of herself.
