Banri had a complex about his face and hid it. But after singing with Akira and Chihiro at the bathhouse Kikonoyu, the singers became closer, and he was able to show his true face. With vocal and dance lessons ahead of their debut, the three decide to see and learn from LEGIT's live performance. However, at the time, it didn't seem like LEGIT was preparing for the concert while Daiki and Eishiro argued as Fuga stared on...

Akira's group is relieved to make it through the commercial shoot without any problems when Lin immediately informs them that their debut has been set. At the same time the three are busy with shoots and interviews, Anela features in an up-close and personal program focusing from now up until their retirement. Various thoughts and memories come back to the surface, including the day Lin and Maoto decided to retire and the establishment of sMiLea Production.

As PROTOSTAR, Akira, Banri, and Chihiro successfully completed their live debut. But for some reason, Chihiro seems conflicted. In actuality, Chihiro is the eldest son of a famous Japanese dance master. Chihiro, unable to get into the swing of practice, is severly troubled that he cannot tell his father he is an idol nor can he tell his friends the situation. Worried about Chihiro who keeps skipping lessons, Akira and Banri visit Chihiro's house──?!

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...!

Akira's determination to never give up and his unfailing faith in Daiki is conveyed through a game of baseball, and with Daiki's recommendation, Akira becomes the group's lead. With each of their thoughts and feelings connected and united as one, sMiLea Production's joint idol live performance finally lifts its curtains for showtime──!
