Several years have passed since the amateur band Second Literature Club spent a summer touring Japan and performing live. When Shikanosuke and his friends graduated from Oubi Academy, the legends they left behind drew several experienced musicians to seek entry into Oubi Academy. Every year, these excellent musicians seek to join the Girls Light Music Club, which inherited the name of Shikanosuke's band, and every year they give high quality performances rivaling the original.
Meanwhile, the Boys Light Music Club has faced nothing but decline. As a club whose only goal was to enjoy music, they've fallen low in comparison to the Girls Light Music Club. Honda Souta was also a member of the Boys Light Music Club, but Souta needed to put on a better performance than the Girls Light Music Club. The reason behind his drive was Yoshimoto Yui, the vocalist and guitarist of the current Second Literature Club. Yui was Souta's unrequited love and his greatest rival who always outdid him. Souta always challenged Yui, saying, "If I can outperform you, then you'll have to go out with me!" The stage for their contest was the upcoming Cultural Festival.
"If I can put on a better performance than the Second Literature Club, then Yui will realize how cool I am!" Souta was full of drive, but the rest of the club was the same as ever. What will happen at the Cultural Festival? What will happen to Souta's one-sided love?!
------------------------------Part Two--------------------- After he graduated from Oubi Academy, Murakami formed his own band, HAPPY CYCLE MANIA, just like he always wanted. The band overcame many troubles and was finally gaining ground as a popular band when a new trouble arose! Their vocalist, Aki, made her solo debut as a professional singer, leaving their band without a vocalist. Murakami thought, "Well, this happens often enough to any band in the industry. We'll figure out something," but he just couldn't seem to move forward. He found himself worrying about their past, their future, and the more he worried, the more he got stuck in a slump. Murakami stopped acting like his usual self, the band grew edgy, and they began to face the threat of disbanding.
Each band member begins to think about their ideals and their dreams, but what answer will Murakami find when they all come together? What lies in store for HAPPY CYCLE MANIA and Murakami?
Many characters from the original game will appear in this grand finale to Kira Kira!
