They would earn their own life with their own efforts.After collecting every crystal, every egg, and the knowledge of how to get their body back, they go to finally meet with their desire.
But the friends they tried to make and the cage who took away their chance at freedom won't make it simple.
They can only hope that they will listen to their side of the story.Good luck, ANGEL. You'll need it.
OR
Angel tries to get their body back, but everything goes horribly wrong for everyone because they can't help being flawed teenagers with too much baggage.
