When something strange comes, "representative families" are randomly selected from around the world to challenge the horror rules. Other families are facing bloody monsters, but in my family... The live broadcast cameras are focused on my ordinary parents who quarrel every day and are on the verge of divorce. But when the global audience saw my mother using a broom to beat the monsters away from the door, and my father using an abacus to calculate the BOSS to death, the whole world was confused: "What kind of fairy family is this?!" What they didn't know was that I, the seemingly most useless daughter in the family, was the one behind all this.
