Only three people show up to their third anniversary concert. Sensing that their careers are in crisis, Aina, Ami, Shiori, and Ruka enthusiastically plan for their concert one year for now, but...

The Idolls attempt to sell tickets to their friends and acquaintances, but reality is harsh... That's when the group discovers that Aina has been keeping her work as an idol secret! What? For three years? Why?

Advertising is important. Though the Idolls attempt to hand out fliers for their concert, nobody will take them. As the idols worry and get caught in a swirling kaleidoscope of despair, Aina has a sudden impulse!

The Idolls think including a special gift will help them sell more concert tickets as well as gain new fans. What do people want...? What's something people desire...?

Ruka is called home and told to take over the family business. Being an idol certainly isn't a stable job. Success isn't guaranteed. But is she prepared to continue working as one regardless?

Aina is sulking?! After seeing how much less popular she is compared to the other members, she repeatedly mimes smoking and drinking shochu. What's more important? How many fans they have, or love?

An opportunity to make their major debut arrives when the a capella world's hidden soldier of fortune, Salvatore Tamai, recommends the Idolls to a record label! However, it comes with certain conditions...

The Idolls decide to become unorthodox idols who slap each other with eggplants! Tickets have sold out! It's smooth sailing for the Idolls! However, Aina's resolve falters when she hears the voices of their fans...

Their major debut is taken off the table, and ticket sales are canceled one after another. Regardless, the Idolls have sworn to entertain their fans! They won't survive unless they keep moving forward.

This is the special 10-day story of struggling idols who fight to fill a 100-seat concert hall. And this is where the special story of a sold-out idol group begins.
