This story is a sequel to Pony May Cry: Brotherhood is Magic

It has been two weeks since Fluttershy had left Ponyville. The note left behind had told her friends that she went off to visit family. It really wouldn't have been much of an issue on its own, but it mentioned that she would return in only a few days. Her friends rounded up a search party and attempted to look for her on their own, but turned up no clues.

Upon receiving a second letter addressed to him, Vergil, a half-breed son of a legendary demon from another universe, decided to attempt to look for her, alone. He vowed to protect her with all of his might and aimed to keep that promise, no matter the cost.
