Funny bit

A young man with black hair and a determined expression stares forward, then the scene cuts to a rapid, blurred motion of a punch connecting with a spiky-haired man, who is then shown in profile with a dazed expression. The sequence continues with the black-haired man leaping into the air, wielding a glowing sword, and delivering a powerful blow to the back of the spiky-haired man, who is now lying on the ground with smoke rising from his back, all set against a backdrop of a dark, cloudy sky and a cityscape.
