Finn the Human rides on the back of his dog Jake through a grayscale landscape, then the scene shifts to a desolate area where Finn, with a determined expression, pulls a rope tied around Jake's neck, causing Jake to be yanked forward; the scene cuts to a rapid motion blur, then to Finn swinging on a rope in a dark environment, and finally to a large, shadowy figure with a glowing white head standing over a small, green character in a dark, cave-like setting, with the Japanese text "交響" overlaid throughout.
