Talk about eating monsters.

The monster appeared in the basement. The little boy went to the basement to get something and met this monster. In the upstairs room, the little boy's parents had another party with a group of men and women, and then it seemed that for some reason the little girl went to the basement, where she saw the monster eating the boy's body, with blood all over her face. The place where this monster appears will affect the electricity, and then the elevator will not sit, little boy (? It seems that this is why I am trapped in the basement. The monster reached the ground, the child's father died, and the mother came down to look for the little girl. They took the elevator up and met the monster. A man was eaten by a monster to save their mother and daughter. A group of people escaped and found that the city had been occupied by unknown creatures emerging from the ground.
