Cold Silence

Two anime characters stand in a dimly lit outdoor area at night, one with short dark hair and a red shirt, the other with a yellow backpack, as white smoke or mist drifts around them. The scene cuts to a close-up of two hands reaching toward each other, one with a white glove, then shifts to a black and white sequence showing a hand holding a spray bottle, a leg with a dark stain, and a person's back, before returning to the two characters walking down a staircase inside a building.
