Elizabeth wants a platinum gear to go along with the rest of her collection and says to talk to Theo to learn more. He tells you that you can get the material from a Rampage Drive, which can be found on the first two floors (as well as the fifth and eighth, if you're that far) of the Clock Tower Labyrinth. In order to get the item to drop, you will need to defeat it with either a light or dark attack (according to Theo), but only light ones will make the Shadow drop the H Drive Gear material. Once you've gotten the item, return it to Elizabeth to finish the request.
