Trivia

 * His/her name "Cerberus" (or Naberius) is probably taken from the book The Lesser Key of Solomon. In the first section of this book, entitled Ars Goetia, several demons are described, Cerberus being the twenty-fourth. The dungeon where Cerberus resided in was the 24th as well. Officially, the name of the 24th demon is Naberius, though it is unclear if there is an association with the Greek Cerberus. In this case, Magi's author, Shinobu Ohtaka, has decided to give the 24th Djinn the name of Cerberus.
