Ep. 9: Detektif mengunjungi Casino Island setelah sebuah ramalan dan menghadapi utang judi serta pemimpin yang diculik.

A ouija board prophecy leads the detectives to Casino Island, which is having its opening ceremony. Upon arriving, the girls meets a strange girl who fell out of the sky who Sherlock names Anne Guardy. While the detectives search for a nearby Element, only to get addicted to gambling in the process, Marine is slightly downhearted to find Miki has become the center of her idol group. When Milky Holmes end up racking up a huge debt, they are challenged by the dealer Noir, who has been possessed by the Decrescendo Element, in an all-or-nothing poker match with the Elements on the line. After winning a few games by luck, Marine is challenged to cross a game board without falling through any bad panels, which she manages to accomplish. Afterwards, however, Marine is kidnapped by the casino's owner, Scarlet Ohada, and taken into the sky. (Source: Wikipedia)
