A young man with spiky black hair lies on his back, smiling and looking upward with his hands behind his head, as the scene cuts to a close-up of a man with a stern expression and a white eye, followed by a sequence of a character in a dark cloak with red cloud patterns performing a high kick, being struck by a blade, and then falling to the ground, while another character in a similar cloak stands nearby, all set against a backdrop of a blue sky with clouds and a forested area.
