But now that he had her, where was he going to hide her? Finally, he remembered an abandoned, tumbledown mansion in the mountains. The door on the big storehouse was lying broken on the ground, but since the house no longer had a floor, he spread a mat in the storehouse after all. He had just lain down on it with the girl when lightning flashed and there was a crash of thunder. Drawing his sword, he got the girl behind him and kept watch through the storm. At dawn, it finally passed.
Puzzled to hear no sound from the girl, Narihira glanced behind him. She was gone. Nothing was left of her but her clothes and her hair. He fled, terrified.
Later he learned that that storehouse was known to eat people. It was not the thunder that had gotten her after all, but the spirit in the building.
It just goes to show that you shouldn't go near a place you don't know. And as for spending the night there, you shouldn't even consider it!
