Who are you?

A character in a black and white uniform stands with their back to the viewer against a bright sky, then the scene cuts to a hand reaching forward in a warm, golden-lit room. The sequence continues with a close-up of a hand gripping a weapon, followed by a character with red hair screaming in distress, another with white hair screaming with a bandage on their face, and finally a character with green hair and glasses looking on with wide eyes, all set against dark, dramatic backdrops.
