Big Moves (RWBY harem x male little brother reader) Being Remade

Everything isn't mine, except how the reader acts. Nothing is mine because if they were I wouldn't be a broke boy.
One day in a land far away there lived a boy who had to do what he had to do.........Nah I'm kidding this not going to be one of these sad stories this is going to be a fun happy one with cool weapons.
