Prologe

This is my first story yay
Ok so in this AU you are Sasha's older sister y/n waybright the reason you got sent to amphibia is because your mom told you to keep Sasha safe and protect her because it was late when they opened the box, you got sent to a random town where they do box fights Wo random creatures.
This is a Marcy X reader fanfic
Sorry if I have bad grammar or spelling (I suck at literature) I hope you enjoy the story
