Akira, a meticulous editor at a major publishing house in Tokyo, harbors a secret: he lives with Koharu, a Hungarian-made love doll. Each night, he speaks to her and finds a long-sought solace in her presence—a comfort he cannot attain even in the arms of real women in his life. But when Kyoko, an intelligent subtitle translator, enters his life, everything changes. A single confession to Koharu about his attraction to Kyoko sets off a chain of disturbing events that spiral into the unexpected.
