A crowd of people are watching a performance on a stage. The stage is set up in a large convention hall or arena, possibly for an event or exhibition. The space has a high ceiling with a visible network of metal support beams. A sign reading "HALL 1" is visible in the background. The crowd is mostly composed of people with dark hair, dressed in casual clothing. Some are holding up their phones to record the event. In the foreground, the back of a person wearing a light-colored sweater with the word "STAFF" and colorful illustrations is clearly visible. The stage has some kind of enclosure around it. The performance on stage seems to feature people dressed in bright colors.
