All Shuichi ever dreamed about was following in the footsteps of his pop idol, Ryuichi Sakuma and the band Nittle Grasper. Together with his best friend Hiro, Shuichi's formed a band called Bad Luck and they've even managed to get signed to a major recording label! Unfortunately, the studio deadlines are looming and Shuichi still hasn't finished the lyrics for any of the songs. What he needs is a little inspiration... but he's been running a little low in that department lately. While Hiro recommends finding a girlfriend, fate has other things in store for him... Walking through the park late one night, Shuichi's latest lyrics flutter away and land at the feet of a stunning stranger that takes his breath away. Unfortunately, that mysterious stranger happens to be the famous novelist Eiri Yuki, who completely crushes the young singer by telling him he has "zero talent". Now, Shuichi's so annoyed that he's managed to finish his song just so he can find and confront Yuki once again. But, are his actions really motivated by anger, or has he actually fallen in love?

As another year begins at Yuigaoka Girls' High School, ushering in a fresh batch of students, the school idol club Liella! is excited to expand their membership. However, Liella! is extremely popular due to the astounding talent they have continuously displayed; thus, new students lack the courage to even consider approaching the club, fearing the rigorous training that might lie ahead. Amid her worries, club leader and co-founder Kanon Shibuya meets first-year student Kinako Sakurakouji and tells her about the world of school idols. This leaves Kinako in awe, but being fairly average herself, she feels she would not be capable of matching the spirited performances of the brilliant Liella! members. Nonetheless, Kinako receives encouragement to join the group and comes to share their dream of reaching for the stars once again in the grand Love Live! Competition.
