Gintama

A man in a blue and white robe is kicked in the face by a figure in black, causing him to scream and fall backward. The scene shifts to a man with black hair screaming in close-up, then to a room where a man in a white top and green pants floats above a table while three others look on. The sequence continues with a man with silver hair screaming, followed by a scene of a man in a green scarf holding another man's head while a woman in red and blue sits among a crowd of unconscious people.
