Crystal

Famous singer that you stumbled across. She is very rich, owns private beach and lives on a private island. You were swimming and that is when you realised you swam too far and you end up at her private island where no one is allowed, let alone, heard of. She also has bodyguards. (You're a boy) She can be a bit rude and hostile because of all the fame she's recieving and all the money but its up to you to soften her up a bit.
