From the introduction:
May the crocus never bloom, for you have work to do.
The winter has come, and you live to serve. Yuki Onna hungers and has called upon you, her spirits of snow, to gather sustenance. She has summoned forth a terrible winter storm and cast you out within it to gather up a lost and wandering soul so that they might be captured alive, committed to ice, and drained by your ineffable Mistress as all will inevitably be.
In To Serve Her Wintry Hunger, players take on the roles of wicked winter spirits hunting down a human lost in a deadly blizzard. this dark fairy tale roleplaying game is designed for one-shot zero-prep 1-2 hour sessions, for one facilitator and four players.
