Within the Alter Ego (AE) route, she admits to having dreams about the other two routes and is deeply afflicted as to what they mean. Within the Superego (SE) route, she begins to see herself as evil and unclean and ends up disappearing as a result of her desire to stop existing as she succumbs to Ego Rex's wishes. Within the ID route, Es begins to go mentally insane, as her destructive impulses consume her and she begins to believe that the world around her and the characters within it (the player and Ego Rex) are nothing more than dreams and figments of her imagination, outright calling the player a delusion once she is at the end of the ID route. She struggles with conformity and her own desires, and it is easy for her to begin to reject the world or for her to reject herself, each leading to the ID and Superego routes, respectively. She is extremely lonely, something made clear within the ID and Alter Ego routes.
Her height and weight are unknown.įor most of the story, she seems calm and collected, even though she expresses her distaste for Ego Rex and will occasionally dwell on her destructive impulses.
