Run Nezuko Run

In a dark, cavernous setting, a young girl in a traditional Japanese outfit with a sword is attacked by a second girl who is bound and has a wooden plug in her mouth; the bound girl is thrown backward, her body contorting as she flies through the air, then lands on the ground, her body twisting and her hair flowing as she is pulled forward by an unseen force, while the girl with the sword stands over her, holding the sword out.
