Kaneki Ken

A white-haired anime character with a bloodied face and a red eye appears in a close-up, followed by a scene of a dark, shadowy figure moving through a dimly lit space with bars, then a side profile of the character wearing a black mask and smiling, a close-up of a white eye with a blue iris and a black slit, a distorted close-up of the character's face with a red eye, and finally a repeating pattern of the character's red eye.
