Kanae is a scientist who serves as the assistant to the main antagonist, Ryuko Saito. Her role in the story places her directly in opposition to the protagonists, the time-traveling trio of Gawl, Koji, and Ryo, and she is part of the forces working to preserve the timeline that leads to the creation of Generators.

The character is of notable importance to the plot's climax, as Kanae is involved in a significant revelation of true identities late in the series. During the final events, she and another character, Takuma, disclose that they are not who they initially appeared to be. This moment is a key turning point in the confrontation with Ryuko Saito and contributes to the protagonists' struggle to change the world's destiny. Prior to this, she is shown interacting with the main characters in more mundane situations, such as providing transportation for them.

No reliable direct information is available regarding Kanae's personal background, personality traits, or individual motivations for working with Saito. Her key relationships beyond her professional association with Saito and her connection to Takuma are not documented. Similarly, there are no details concerning her development throughout the story or any notable abilities she may possess.
