Rengoku

A woman with black hair and red eyes holds a young boy with spiky blond hair and red eyes, who looks up with wide eyes; the scene cuts to a hand gripping a sword with a flame-shaped hilt, then to a close-up of a man's face screaming in pain as the sword pierces his neck, followed by a shot of the blade being pulled out, and finally a close-up of the boy's face, now with a blue eye and blood on his cheek, as he looks down with a pained expression. The setting is a dimly lit room with traditional Japanese sliding doors.
