Ripple

Ms Ripple is a wealthy jewel collector who brought along many of her most precious jewels on-board the ship that Ash and his friends were traveling on while in the Decolora Archipelago. A screenshot on the tablet has the romanization of her name as "Lipple" by deciphering the anime language in the window title but it is obvious from the other characters in the episode that her proper name is Ripple as it ties in with Shoal, Tide and Current.
