You are one of the Stand. From another Joestar. But one day you aren't with your User.

You wake up in a random room, the Burning Down the House, or the Ghost room. With all the other Stands (Besides the villains) from Hermit Purple, to Stone Free. Includes not just the main Joestars, but the friends of them like Echoes ACT1-3 to Spice Girl. One another Stand goes to talk to you, Star Platinum.

Star Platinum: "Who are you. What are you even supposed to be."
