A seven minute epilogue to the TV series, released as an OVA. 

At a Shinto shrine in Shimoda, there is a large rock. It is said that if four close friends gather around the rock and all wish for the same thing, that wish will come true. As four friends, Natsumi, Saki, Yuka and Rinko, gather around the rock like they used to in their childhood, they soon find the rock can indeed grant people's wishes. With only a short amount of time before Saki is due to transfer schools, the girls spend a summer filled with magic. <br><br>
