When she was young, she met a silver demon that eats the hearts of women, and said, "When I grow up, I will come to eat you." Fubuki, whose parents were absent and saw the demon on transfer student Zenzo Chikamatsu, relocated to a ten-year-old house, but only ten years was the silver demon himself. In the decade when she loves blowing while she watches, she tries to make it a bride. Fubuki rebounds violently while being hit by him.
