On the day of Akira, Banri, and Chihiro's group unveiling, a typhoon forces them to cancel their live outdoor performance. Instead, the three who want to express their gratitude directly to the fans who stood by them as online singers propose a crowdless online live stream. But Lin was adamantly against it. He wanted a properly prepared event for the three-man group, but with the help of LEGIT and JAXX/JAXX, he changed his mind. The live stream somehow begins to take shape thanks to everyone's cooperation, but the power goes just before starting...?!

With Chihiro's problem solved and their bond deepened, PROTOSTAR arrives in Hawaii together with LEGIT, JAXX/JAXX, and their leaders, Lin and Maoto. Actually, it was for a magazine photo shoot featuring the idols affiliated with sMiLea Production. Still, Akira, who was overseas for the first time, led the way putting everyone in high spirits. Each of them had a good time eating and sightseeing during the shoot. But on the flight home, they suddenly realized Banri was missing...!

A few years back, Homare, Izumi, Jun, and Kanata lived together in a share house while working as an idol group, but they were unexpectedly fired. While in a slump, they found and helped Gakuto who had apparently collapsed from hunger and was lying on the side of the road. The four were moved by Gakuto, who came to Tokyo to make music, and his singing. Later on, Izumi is invited by Homare and the others to join a band. But try as he may, he worries about the future, unable to take the first step forward...

Confusion hits everyone at sMiLea Production when an article in a weekly magazine states that the person who forced Lin to retire from being an idol was Daiki. The group's lead still has yet to be decided, and there are rumors that the joint live performance will be canceled. But while everyone gets increasingly anxious, only Akira continues to believe in Daiki. Akira does his best to support LEGIT's work and make the joint live performance a reality with persistence and a positive attitude. One day, Akira runs into Daiki at the same school he attends for supplementary lessons...!
