Vanished Settlement, Girl's Choice

Today, the sister and father are doing some kind of work. The protagonist is not allowed to help. The protagonist feels a sense of alienation, but other than that, the sister and father are kindly and warmly treating the protagonist. The protagonist goes out to the forest to look for tree fruits, and when he returns to the settlement, thinking that he will pass the time as usual, the voices of people and sounds are not heard, and he feels a smell of blood. Red liquid dripping here and there, fragments of collapsed houses. When I walked around, the houses of each family had been destroyed violently and there were no people. The protagonist rushes back to his own house in a hurry. The house is destroyed like the other houses, and the inside of the house is the aftermath of the disaster, and the sister and father are gone. The protagonist shivers and sits on the spot. "Oh, there are still people here," a mysterious woman's voice is heard, and when the protagonist looks up, there is a woman he has never seen before. She is beautiful, but has a cold expression. When the woman tries to hit the protagonist with the cane she is holding, a black-haired young man appears and deflects the cane with a sword. "Oh, do you understand?" the woman says, seemingly resentful. "No attack is necessary because there is no resistance, not a slice," the young man says. "Yes, you can go with that," the woman says, stretching her back, and walks away from the settlement.
