Rathie's shop, known as Kurumizawa's shop in the Japanese version, is a hobby shop, owned by Rathie in New Domino City. Among its merchandise are figures and posters of Duel Monsters, particularly female ones.
Carly Carmine sought Rathie's help here. She got him to assist her in her investigation into the Signers and the Crimson Dragon. He managed to research the Arcadia Movement and compile information into a folder. As he was unwilling to hand it over for free, Carly handed him a rare Dark Magician Girl figure in exchange.
