Note: "Hitomi" means pupil or iris (as in the "color" of the eye). The staff chose her name to symbolize the eye which "can see the invisible." Her name was initially to be written in kanji, but the staff eventually opted to go with hiragana. In both Katsu-Aki's shounen and Yuzuru Yashiro's shoujo manga versions, her name is Hitomi Hoshino, a name which was also proposed earlier for the anime version. ("Hoshino" as written can be a wordplay on the phrase "of the stars.")

When creator Shouji Kawamori first conceived of a story on a world invisible from Earth (more than five years before the anime's debut), Hitomi was initially not the protagonist. In fact, it was only some years later in development that the production staff decided to have a female main lead. Director Kazuki Akane takes credit for insisting that Hitomi have short coifed hair instead of the long hair in Nobuteru Yuuki's initial designs.
