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──?!

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.

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──?!

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──!
