The scene is set in an indoor gymnasium with yellow walls, a blue floor, and a net-like material covering part of the wall. At the front, a row of seven adults, all wearing white karate uniforms with black belts, stand facing the camera. They are positioned behind a group of children, who are also wearing white karate uniforms with numbers on their backs, kneeling on the floor. There are at least ten children kneeling, forming a semi-circle. A poster of a high jumper is visible on the wall above them. The adults appear to be instructors or officials, while the children seem to be students or participants.
