[spoiler]Some early movie promotional material identified her as Promethium II, and indicated that she was the daughter of the Queen Promethium of the Machine Empire of Galaxy Express 999 (another of Matsumoto's works). This idea (and the suffix, II) was later dropped, however, and Millenial Queen Promethium/Yayoi was considered to be the person who would eventually become the Machine Queen (see Maetel Legend).
While shown with rounder eyes in the anime TV series, she is shown with almond-shaped eyes in both the manga and the anime film and looks just like Maetel from Galaxy Express 999.
While Yayoi is Professor Amamori's private secretary in all three versions of the story, there are the following differences:
In the anime TV and manga, Yayoi lives on the second floor of a ramen shop run by an older couple who have adopted her as their daughter. She has a tiger-striped cat.
In the anime film, in addition to being Professor Amamori's private secretary, she also teaches at a school and lives in a high-class apartment.
