Well all three worlds take place in Japan, so same language and money. Aikatsu system is different, but they probably have records of their songs, and they sing it themselves too. They have it saved in the Aikatsu pass, including stage and appeals. They also acknowledge different systems by not letting 2 idols from different series use appeals
