A mysterious snowstorm kicks up in Equestria, and the Weather Factory pegasai have absolutely no idea what caused it. Little do they know it is not a what, but a who. Who can stop Gensokyo's resident 'strongest' ice fairy before Equestria is buried in snow forever?

One shot inspired by the song 'Cirno Invades Equestria' by LunaticBone and HertzDevil. Hope you all enjoy.

Features unimportant OC Ponies, Human (or youkai, as the case may be) and partial shipping that I intend to delve deeper into in the sequel.
