Ghouls

A close-up shows a character's mouth smeared with blood as a finger presses against their lips, followed by a shot of a character's leg stepping onto a mechanical device against a sunset sky, then a character with short dark hair crouching on a wooden floor, another character with dark hair and a purple garment looking down with a serious expression, and finally two characters standing together at night, one with white hair and the other with black hair and a red eye, all set against a city backdrop.
