Inspired by the songs Daughter of Evil by Kagamine Rin, Servent of Evil by Kagamine Len, and Daughter of White by Yowane Haku.
This story is about Pride, one of the seven deadly sins. Princess Sunset Shimmer is known as the daughter of evil in her Yellow Kingdom but her servant Sunburn (Who is also her twin brother) doesnt think so. I would explain more, but then I would ruin everything.
