Sosuke Yaotome, who is trying to pull out the rising popularity of Tamaki and Sogo, has taken advantage of the weaknesses of Tamaki who hastened his debut and invited them. After learning about the circumstances of Tamaki, Riku and his friends talk directly to President Kotori Yu so that he can make his debut as IDOLiSH7. However, the president's decision is to make a debut with only Tamaki and Sogo, who were targeted by Yaotome, based on the possibility that all seven of them will make their debut in the future. At that time, IDOLiSH7 receives a request to appear in the music program "Music Festa".
Après un concert difficile mais réussi, les IDOLiSH7 sont fin prêts à lancer leur carrière… mais la popularité des sept membres est loin d'être homogène. Les deux les plus populaires, Sogo et Tamaki, sont très convoités, ce qui engendre un malaise au sein du groupe.
Der Vorsitzende von Yaotome will Tamaki und Sōgo für sich gewinnen und macht ihnen ein großzügiges Angebot. Sōgo ist sofort dagegen – doch Tamaki zögert. Was ist der Grund, weshalb er unbedingt ins Fernsehen will?
Yaotome Sosuke, presidente da Yaotome Productions, se aproxima de Tamaki e Sogo com uma oferta tentadora: Sogo o rejeita imediatamente mas Tamaki pensa em aceitar a proposta. Será esse o fim do IDOLiSH7...?
