Originally, Naoto was the main protagonist of non-canonical spin-off Persona x Detective Naoto prior its canonization being debunked since the release of Ultimax.
She returns as one of the Season 1’s DLC playable character in BlazBlue Cross Tag Battle.
A young detective working for the police in Inaba. Descended from a family of detectives, she too wanted to become one, but living under the impression that only men can excel in the profession caused her to disguise herself as a male. During the murder case in Inaba, which Naoto and the rest of the police were investigating with little success, she picked up on the fact that all of the victims appeared on television before being kidnapped. Thus, she allowed herself onto a TV interview and waited to be kidnapped, hoping to discover more about the case. When Naoto was taken and forced into the TV World, she found her Shadow inside the Secret Laboratory, who revealed to the Investigation Team about her true gender and fear that once the case is over, the police will stop caring about her because she’s just a child. Upon accepting her fears instead of denying them, Naoto gained her Persona and chose to work with the Investigation Team for the rest of the case.
A few months after solving the Inaba serial murder case, Naoto joins the Interpol, where she unexpectedly meets the Shadow Operatives, Aegis and Mitsuru Kirijo, as they investigate the P-1 Grand Prix Tournament that is taking place inside the TV World. At some point as an Interpol agent, Naoto began to research about the history of Dark Hour, which happened in many years ago during Persona 3 storyline.
