Popular musician Avril Lavigne has already worked together with pop duo Puffy, and now she will be teaming up with singer Ai Otsuka as well. When Avril returns to Japan for a concert at the Tokyo Dome on September 16, both Puffy and Ai Otsuka will be making guest appearances on stage.

Avril remarked that she wanted her show to be like a "rock party." Puffy was a natural choice as a guest, as she and producer Butch Walker previously worked with the duo on the song "All Because of You," released this past May. Ai Otsuka is said to have been chosen due to her status as a symbol of the "girls rock" scene.
