Classic.

A character with white hair and cat ears smiles and raises a hand in a dimly lit, colorful setting. The scene transitions to a group of characters dancing on a stage with flashing lights, including a character in a red suit, one in a white outfit with cat ears, and another in a black suit, all performing synchronized dance moves. The sequence ends with the silhouettes of the characters standing on a stage with the illuminated word "GUCUKOKU" in the background.
