The seasons in Gensokyo have gone out of control, with the Hakurei Shrine experiencing spring, Youkai Mountain experiencing autumn, and the Forest of Magic experiencing winter. What's more is, all of the fairies have gone completely beserk, and seem to be stronger than usual as well. All of this gathers the attention of the heroines and leads them to investigating the incident.
