Using this Gochizo set is a breeze. First, locate the new switch on the units. Flipping it allows you to choose between Shouma and Gochizo modes. When in Shouma mode, just sit back and listen to the fun dialogue between Shouma and Sachika. Switch to Gochizo mode to experience different emotions of Gochizo. If you want some surprise voice - overs, turn on the auto - chat mode. When using the Gurucan, you'll enjoy the show's BGM. Remember, the DX Henshin Belt Gavv is sold separately, so you'll need to get it if you want to use both Gochizo with the belt. As for maintenance, keep the units away from water and excessive heat. A soft, dry cloth can be used to clean them. Also, store them in a cool, dry place when not in use to ensure they stay in good condition for a long time.
