One piece!

A female character in a school uniform falls through a dark, cloudy sky, releasing a small object that floats upward. The scene cuts to a male character in a red coat, viewed from behind, who turns to face the camera with a determined expression, gripping a sword in his mouth. The sequence ends with a close-up of his face, showing a focused gaze and a bandage over one eye. The setting is a stormy, overcast sky with a distant, ominous landscape.
