Toradora!

A female anime character with long dark hair and a school uniform stares intensely, then the scene cuts to her and a female character with brown hair falling through a classroom, followed by a close-up of the brown-haired character's determined face, then the dark-haired character swinging a bat-like object at her, and finally a close-up of the dark-haired character screaming with the subtitle "jigoku" as the screen cuts to black.
