In the midst of this, a team of five girls led by Kanon Shibuya discover “school idols.” —I love singing! I really do! And I want to accomplish something with it! So the hopes of these stars, still small in stature, begin to accumulate…and so begins the “School Idol Project” of five girls with a blank slate and infinite potential.
