Shikanosuke Maejima is a student at the Missionary school, Oubi Academy. He doesn't attend his club, he doesn't put much effort in his studies, all he does is show up at his part time job; in short, his life could be better. One day, he meets a strange girl, Kirari Shiino, at work and before he knows it, they've formed a punk band. The band consists of Shikanosuke, Kirari, his childhood friend Chie Isurugi, and a rich but weak young lady by the name of Sarina Kashiwara. The four of them are members of the Second Literature Club, which has hardly any active members and is already scheduled to be disbanded. This band is their chance to stand out and give one final farewell at the Culture Festival. The challenge was foolhardy, but after eccentric training they managed to succeed and rock out the peaceful Oubi Academy with their debut performance. That should have been it. They were satisfied. They should have returned to their normal lives. However, their final performance at a local Live House became a hit on the Internet and requests for their performance start flying in from far and wide. One problem: exams are coming up and their parents are opposed to the band! Who cares! The four of them embark on their final adventure, a long tour of Japan, armed with their dreams and their instruments, all aboard a rickety van that could fall apart at any moment.

This is an after story of Kira Kira. It has two parts: First and Second Stage First stage concentrates on hotblooded young guy named Souta Honda. He loved two things in this world: rock and his childhood friend Yui Hoshimoto. But attempts to improve relations with both always turned out a total disgrace for him. After one more fail he promised Yui that he'll form his own band and became "bright like the sun" to make her love him... Second stage is, in a way, a continuation both for Souta's story and original Kira Kira story. It tells about preparations for the large concert celebrating the 5th anniversary of Murakami's group, Happy Cycle Mania and bonds all old and new characters together.

A collaboration fandisk celebrating the 5th anniversary of OVERDRIVE, featuring a crossover between Kira☆Kira and DEARDROPS. Riho watches Kirari and Shouichi’s overseas performance on TV and sees that Shouichi is enjoying it more than before. She wonders if she would be able to beat Kirari. At that moment, she never thought that she would have a chance to do just that. [From Micchi's [url=http://omochikaeri.wordpress.com/2011/11/01/november-2011-eroge-releases/]blog[/url]]
