While not specifically named in the English dub, they are called Otogi girls (御（お）伽（とぎ）ガールズ Otogi gāruzu) in the Japanese anime. (Ryuji Otogi being Duke's name in the Japanese version.) In the episode credits, they are simply called girls (ガールズ gāruzu) and are voiced by Noriko Namiki, Rumi Shishido and Yoshiko Iseki. They are based on three girls from the manga, who had a similar role, but did not dress as cheerleaders for Otogi's games. In character lineart, the individual members are labelled "A", "B" and "C".
