Falling into the sky

A young boy in a dark suit looks up in surprise as a large, white, mechanical leg descends from above, its foot landing on a pole just above his head. The scene then cuts to a high-angle shot of the boy hanging from the pole, looking up at the mechanical leg, before transitioning to a bright, colorful sky with a lone figure silhouetted against the sun, followed by a shot of a green-haired character peeking out from a wooden structure.
