2. In the setting, Jolyne Kujo's body double is called "STONE FREE" (English name: Stone Free), which is also translated as "Stone of Freedom" in Chinese.
In the official setting, the destructive power, durability and growth of Stone Freedom have all reached Grade A, and it is a humanoid body double composed of lines. This melee film has a strong attack power and can also be broken down into lines.

Unfortunately, after all, the publicity for PV has a limited duration, and we haven't seen many other stand-in messengers, but there should be many other publicity PVs revealing new information one after another.
