Because two new members had joined his club, which had always been a lonely place! "That's it! We want to experience a sparkling springtime of youth like the Baseball Club!"... And so, the three idol geeks, Yamada, Kouno, and Sugimori, begin their activities to produce an idol group and make their school festival concert a success!
