Anime

A blue-haired girl in a school uniform stands in a desaturated city street, surrounded by swirling smoke, as the scene cuts to a red-haired girl in a school uniform being attacked by a bloodied figure, with another girl reacting in shock; the sequence repeats with a close-up of a distorted face and the red-haired girl cowering in a dark room, before returning to the bloodied girl standing in a vibrant, red-tinted urban setting.
