Kill me

A large, multi-eyed creature with a gaping maw appears against a dark, mountainous night sky, then the scene cuts to a close-up of its open mouth. A character in a black and white outfit with "四代" written on the back is shown from behind, facing the creature, then the scene shifts to a character in a black and white outfit being pulled by a chain across a dark field. The sequence ends with a character in a dark cloak standing in a dark, outdoor setting.
