The scene is an indoor sports arena with a brightly lit blue floor marked with yellow lines. In the center is a square mat with a blue and red pattern, where two people dressed in white karate uniforms are engaged in a match. A referee in black stands nearby, observing. Spectators sit in the green stadium seats surrounding the mat. A man sits in a chair in the foreground, facing the action. The back of his shirt has "TATAMI 2" printed on it. A water bottle sits on the floor in front of his chair. A chain barrier runs along the edge of the blue floor near the camera. The lighting is bright, and the overall environment suggests a competitive sporting event.
