Mrs. Ripple (Japanese: リップル Ripple) is a character of the day who appeared in Cilan and the Case of the Purrloin Witness!.
Mrs. Ripple is a jewel collector who displayed her collection on a cruiseship. Another jewel collector, a Gentleman named Mr. Shaw, came up and showed great interest in one of her rare jewels, called the "Eye of Liepard", and started making offers for it. Naturally, however, Mrs. Ripple declined each time. After the Marine Cup Tournament, Mrs. Ripple found out that the Eye of Liepard was stolen from her collection, and accused Mr. Shaw of stealing it, since he was shown to have broken in to her room on the security camera. However, upon further inspection, it was revealed that when Mr. Shaw entered the room, the jewel was already taken; he only trespassed for the purpose of getting another look at the Eye of Liepard. Mrs. Ripple and Mr. Shaw came to good terms after the real criminal was revealed to be a participant in the tournament named Teaque.
