That Band Fic

This is basically Eddsworld but in a different dimension, on crack and then stuffed through a dimension collider.
Bottom line, four girls, Ripley, Harper, Rowan and Casper are all in a band they made called "Pyro Mania". They haven't quite been "discovered" yet and play at local cafes and gay bars. Each girl has their own challenges.
Ripley, the singer, is the loudest and most upbeat of the group, constantly bringing good energy to hangouts and practices, but she is struggling with issues with her family and is constantly out of the house due to her parents and brother fighting all of the time.
Harper is the most contrary bassist and is angry 90% of the time, but if she wants to, she can be deep and supportive. She is not doing so great in school, and her grades are going down with her motivation.
Rowan, their drummer, is the quietest but most supportive girl, and she loves listening to other people talk, but she's not so great at talking, even to her friends. Rowan tends to bottle things up until she can't anymore...
Casper is the backbone of the group, the creator. She plays guitar and loves her friends. She does have body image issues and constantly wears baggy yellow hoodies and jeans.

Each girl has their own lives, secrets and interests, but when they are together, they feel comfortable and loved. So what happens when one girl's secret threatens to tear the group apart...?
