Cold

An anime girl with a ponytail and red jacket walks down a staircase under a red and purple light, then the scene cuts to her in a close-up, followed by her kneeling at a podium in front of artillery, then a view through a scope of a girl holding a syringe, then a shot of a boy and girl looking at each other, and finally a portrait of a girl with red accents on her face being viewed on a phone screen.
