OneyNG

A cartoon character with long black hair and a pale face grimaces while holding a wand, then the scene cuts to a red-haired boy in a school uniform laughing maniacally while holding a wand, followed by a close-up of a girl with brown hair looking terrified, then the two characters appear together with the black-haired character looking angry and the red-haired boy still laughing. The setting is a dimly lit stone-walled room.
