Chainsaw man

A woman with long blonde hair hangs upside down in a dark room with traditional Japanese windows, then appears right side up, smiling and touching her chin. A hand grips a red-bladed weapon, followed by a man with blonde hair and an eyepatch adjusting his jacket outdoors. The sequence ends with a dark, abstract image and a grotesque figure with a mechanical head and blood-stained body standing in a dimly lit space with other figures in the background.
