Akira is unable to hide his surprise that he was singer KIKUNOYU, but decides to try his hand at being an idol. When visiting the agency office, he is told he'll be in an idol group with singers EVAN (Banri) and Suzu (Chihiro). On their way home, Banri, wearing a mask and sunglasses and dressed suspiciously from head to toe, suddenly gets frightened and hides when Chihiro reaches out for his mask. There seems to be a reason for his suspicious getup──?!

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.

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...?!

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...!
