Princess Syalis's full name, according to the manga comic, is Aurora Syalis Goodreste. These three names all refer to sleeping:
- Syalis refers to "suyasuya", the Japanese sound effect for a peaceful sleep (the English counterpart is "zzzz")
- Aurora refers to the La Belle au bois dormant (1959) princess
- and Goodreste is self-explanatory (in Japan the name is "Kaymin", named after "kaimin", the Japanese word for "good rest").
Another reason for Cubey's name being changed in the Anime (Originally Named "Bussy" in the Manga) is because the Term Bussy is a Slang word sometimes used in the LGBT Community that refers to, in as Polite as Possible Terms, a Man's Butthole.
The Sucubus who the Princess uses as her Body Double is Named Cubey in the Anime; however, the Manga dubs her as "Bussy." Perhaps this is because of some kind of Translation issue.
The Manga reveals the Harpy actually has a Younger Brother, who is a Musical Composer; he has a Cameo in the Final Episode.
