Toomics Chat offers AI-powered character chats. The payment currency used in Toomics Chat is GEM. Your Toomics Coins can be converted to GEM. If your GEM balance is insufficient, the required amount of Toomics Coins will automatically be converted to GEM and deducted. If you do not want GEM to be deducted automatically when unlocking images, you can require confirmation before each unlock. Turn off [My > Auto Unlock], and GEM will be deducted only after you confirm the unlock.
