Dazai was the father of a little girl for whom he had recently bought a toy castle in the old market. It was beautifully decorated, it seemed ridiculous how cheap it was.

One day, Dazai began to notice that the doll inside the toy castle looked rather suspicious. His daughter said that the doll was changing its position. Dazai didn't believe it, but one night he decided to check it out to satisfy his uneasy feeling.
