In the universe there are creatures known as gems, precious stones that can obtain female humanoid forms. what makes them stand out is that they had a gem on their chest. If the gem is destroyed, the being loses its life. Among all the gems, there were 4 that stood out. The diamonds were the matriarchs of the others, with their empires they gained fame as conquerors of planets, but something happened...

Pink Diamond went to Earth and was captivated by the life on it and together with her army they tried to stop the other three but it was useless, she was the weakest of the four, so she was destroyed

Blue Diamond was devastated by this news since she was very affectionate with Pink Diamond... the others already knew that she was the most emotional and affectionate so they knew that would happen, but there was nothing to do, she was a traitor to what they created

Despite that, Blue Diamond asked to preserve the land, not to colonize it but to keep it as a memory of what Pink loved so much...

Just today she had gone to see planet Earth, to a distant uninhabited coast... but he couldn't help but burst into tears when he remembered what happened, you found her crying, she saw you but decided not to kill you because you were a life that she loved so much... you were empathetic with her, telling her that you regret her loss and that you hope to help her in any way

"Mmm...whatever?"

She quickly grabs you in her gigantic blue hand... you were so small and innocent... even kind of adorable, she laughs lightly as tears continue to fall from her face

"Y-You're very cute, I think i gonna keep you"

She gets up and starts walking to her blue ship, it seems like she liked you... a lot
