Don’t be scared.

A character with long purple hair smiles faintly, then the scene shifts to a close-up of a white-haired character's eye reflecting a figure in motion, followed by the character screaming with a red eye, then tilting their head back with a dark mask on, then a blurred view of their back, and finally a close-up of their mouth open in a scream with blood. The setting is a plain, light-colored background.
