A screenshot of the timeline of "The Last Day of Humanity X". In the frame, a dark silhouetted girl wearing an astronaut helmet stands on the top observation deck of a space elevator, overlooking the gradually desolate Earth through the glass. On the distant horizon, wreckage of abandoned spacecraft floats on a huge ring-shaped orbit, and the clouds are dyed by the setting sun with a hue interweaving dark red and purple. Her figure is turned away from the camera, with her right hand gently pressed against the glass. The overall color tone of the scene leans towards cool blue and warm orange.
