This story is inspired by a short film I watched a couple of years ago. Unfortunately, I can't find it (nor do I remember its' name).
Update: all thanks to a kind stranger in the comment section, I now know what the film is. Check the comment section for details.

After her defeat, Sunset discovered something called [STAND]. As she decides to use this power for good, Sunset is now tasked to protect her other friends from the attacks of her new found enemies. Stand users attract each other. However, this attraction may draw enemies to her sooner than later.

Sunset Shimmer
Stand Name: Days Gone By
Special Ability: Record the [Cause] and [Result] of an event, and remove the [Result] by erasing the [Cause]. By doing so, Sunset has effectively created an alternative reality where the event never took place. Her stand also allows her to switch between reality where the event took place, and the reality where the event never occurred.
