At the live performance, Akira is moved by the presence of Daiki, who looks like the main character of Akira's favorite hero anime, "Crossfire." Revved up, Akira and his group get inspired for their lessons, but the dance lessons particularly seem hopeless. Later, it's decided that the three of them will get to participate in a commercial shoot as LEGIT's backup dancers. Although there's not much time before filming begins, LEGIT gives them one-on-one dance lessons. Akira, who fretfully practices yet makes little progress, begins feeling impatient and makes a proposal to Banri and Chihiro.

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...?!

JAXX/JAXX's nationwide tour finishes, and during the after-party, Rin and Maoto announce that they have decided to hold sMiLea Production's first-ever joint live performance. While PROTOSTAR is excited for their first concert with a live audience, and LEGIT and JAXX/JAXX get fully motivated, it's decided that they will all perform a song written and composed by Maoto at the joint live show. While the important role of the group's lead has yet to be chosen, a suspicious reporter reaches out to Daiki──!
