Huntress

A dark, snowy night scene shows a large, shadowy creature with horns and a long tail standing before a building with barred windows, snow falling around it. The scene cuts to a close-up of a hand gripping a sword hilt, then to a woman with long black hair and glowing red eyes, her face smeared with blood, her expression shifting from a grimace to a focused stare, before the view zooms into her intense red eye. The sequence ends with a young woman in a school uniform running down a dimly lit hallway, pursued by several men.
