After a overnight stay in a house at the bottom of the mountain they live on, fourteen year old girl Sumiko Kamado returns home to discover her five siblings, thirteen year old girl Nezuko, twelve year old triplets Takeo, Hanako and Shigeru and eleven year old boy Rokuta, all dead in the snow while their parents Tanjuro and Kie are missing. While Sumiko is trying to find out what she should do, her five siblings are revived as demons and tackle her to the snowy ground. However, her life is saved when young man Kagaya Ubuyashiki, who leads a ancient organization known as the Demon Slayer Corps, hauls the five newly turned demons off her and helps her get up off the snowy mountain ground.
