Underground city (rewrite)

In this story, Marcella is the only human on the planet but not all human. She lives underground since she has no where else to go. Her mission is the catch every monster and bubble them. That is all gonna change when scrooge and gyro noticed life underground guess she still having the adventure of a life time.

Yeah this is part of the Steven universe show but for my character, she's a girl who's the daughter of rose quarts ( aka pink diamonds )

Don't judge me, I just walk around until the inspiration hit me

Hopefully you all will like it like I enjoy writing this series
