Remilia Scarlet, a vampiress over five hundred years old, wakes up one dandy dusk to find out she isn't in Gensokyo. Even worse, she's become equine.

Needless to say, she's rather angry about it.

Armed with her Gungnir, her ability to control fate on a whim, and her own wits, she decides to conquer Equestria.

Except there's a problem: namely, a shrine maiden who somehow got into Equestria as well. Where in Makai is Yukari when you need her?

Crossover with Touhou, particularly Embodiment of the Scarlet Devil. Told from Remilia's perspective. A collab with this pony. Chapters are kept relatively short, but not short enough to render this 15 chapters in one go.
