15 Bishoujo Hyouryuuki is the brainchild of adult game creator Takahiro and anime character designer Kuroda Kazuya. The name is a wordplay on the Japanese title (15 Shounen Hyouryuuki) for Two Years’ Vacation, a children’s adventure story by Jules Verne. Toei Animation adapted 15 Shounen Hyouryuuki into a 1982 movie, and Nippon Animation remade the story into a 1987 television special.
