Painkiller

A group of students stands in a large hall with red and white striped pillars, facing a stage where a confrontation unfolds. The scene cuts to a close-up of a smiling girl with brown hair and a star-shaped accessory, followed by a shot of her with glowing pink energy lines radiating from her. The sequence then shows a girl in a school uniform sitting on the floor of a dark room, covered in pink liquid, before the camera pulls back to reveal her suspended by ropes in a gymnasium, with a poster of two girls on the wall behind her.
