Senpai!

A man in a white shirt and dark pants stands before a green-lit backdrop with sparkling lights, then the scene shifts to a man in a dark suit walking and turning on a dimly lit stage with red lighting, followed by two men in dark suits on a stage with a red-lit background, then a man in a dark suit standing on a stage with metal scaffolding, and finally a man in a white shirt and light-colored pants standing on a stage with a crowd holding up lights, turning and raising his arms.
