Kakashi

A man with spiky white hair and a black mask holds a sword behind his head, then brings it forward in a swift motion, his face showing intense focus. He is in a forest, and the scene cuts to a wide shot of him falling backward through the trees, followed by a close-up of his hand gripping the sword as it shatters, and finally a close-up of his eye, which has a red, three-pointed star pattern.
