Adderall

A white-haired man with red eyes and a scarred face appears in close-up, then is seen in a city at night fighting a large, dark creature with glowing purple blades, followed by a close-up of a hand with sharp, red claws, then a shot of the man from behind looking down, then the man with his hand on the head of a black-haired man with red eyes, and finally the white-haired man is seen from behind looking up at a figure with a long red tail climbing a wall.
