The website of the witches

A razor blade and several yellow pushpins lie on a wooden floor next to a blue cabinet, then the scene cuts to a distorted, pixelated face on a black background, followed by a high-angle shot of white birds flying over a city street, then a close-up of a character's eye reflecting light, then a girl in a school uniform sitting on the floor with her hands covering her face as another girl points a knife at her, and finally a close-up of two girls' faces, one with red hair and the other with blonde hair, smiling at each other.
