Deep down low

A young boy with dark hair and a white mask peeks from behind a wooden door, then the scene cuts to a close-up of a man with spiky black hair and a scarred face, followed by a shot of a boy with blond hair and whisker marks screaming in pain, then a man with a headband and a red mark on his forehead looking shocked, and finally a close-up of a face with glowing red eyes and a red mark on the forehead. The setting appears to be a traditional Japanese-style interior with wooden walls and sliding doors.
