Kira Kira is a musical erotic visual novel about a group of students at a missionary school who decided to start a punk rock band.

"Love, Journey, and Rock'n'roll!!"

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.
