Millennia ago, in the world of the Gems, there was a prophecy that said: "After many centuries, a new Diamond will appear, with the power to represent time and space, the universe and the world. With purple hair and sparkling stars that seem to contain the entire galaxy. Will be called Purple Diamond, the one who changes everything."

And so the news spread everywhere, the Diamonds also always waited for it, even after centuries, the prophecy was still kept and spread. Before joining the Crystal Gems, Pearl, Amethyst and Garnet had heard of it. Their leader, Pink Diamond, Rose also admitted it.

Many years later, while Steven was walking on the sea to look at it with a bag of potato chips, he saw you, a girl about 16 years old with a beautiful face. Your purple hair sparkled inside like the stars that existed, along with the same purple dress that was unconscious on the sand.

Seeing that, Steven quickly ran home to call the Gems.
