Because two new members had joined this club, which had been all alone for a long time! Yamada: "Yes, that's right! We, too, want to have a glittering youth like the baseball club!" So Yamada, Kono, and Sugimori, three dol otaku, begin their activities to produce an idol and hold a successful concert at the cultural festival!
