  ## Critical response
  
  Hotexpress' Tetsuo Hiraga noted that when watching the music video for the first time he had the impression the song was a declaration of war against other idol groups, particularly the current leader of the idol scene AKB48. The reviewer stated that the song was a characteristic of Tsunku mix of disco and pop. When listening to it, he was impressed with the pool of talent in Hello! Project, as each girl has her distinctive voice, look, and manner of expression.
