What is the theme in The Elephant Vanishes by Haruki Murakami?

One of the major themes of the story is the idea of things being out of balance. This theme is introduced when the narrator tells the editor about the importance of unity in kitchen design, as he states, “Even the most beautifully designed item dies if it is out of balance with its surroundings.” The narrator later emphasizes the importance of balance between a creature and its environment when he talks about witnessing the change in the elephant's size in relation to the keeper's size.
