Psychos?

A red-haired anime character's face is shown in extreme close-up, their mouth open in a scream and their eye wide with shock, as a glitch effect distorts the image with red and blue chromatic aberration. The scene cuts to a high-angle shot of a female character in a school uniform lying on the floor, holding a knife to her own neck, followed by a close-up of her hand gripping the knife with blood on her arm, then returns to the distorted close-up of the red-haired character's eye.
