A little girl who never parts with a mysterious egg lives in a surreal world of darkness and shadows, where she spends her time collecting various vessels and artifacts. The world she inhabits consists of abandoned cities, bones, the shadows of people, and the shadows of animals. The shadows of people hunt the shadows of animals. Remnants of weaponry sprawl across the world, seemingly uncontrolled. The world is covered in dusk, and on a large hill stands an ark that saves no one.
Critics describe it as "one of the most beautiful and lyrical films in the animation world," noting that "its surrealist beauty and slow pace create an atmosphere akin to Zen, unlike any other anime."
