It is summer break and Aya complains about the heat, so she decides the girls should go to the beach. Due to Miki's aunt having a seaside inn in Kanazawa, they arrange to go there. In the inn, Aya comments on some strange looking shogi pieces. Midori realizes they are not for shogi, but goita, a local specialty game that she is heard of but has never played. Since it is a four player game, Miki's aunt joins them. She reminds Miki that she played before as a child, but Miki does not remember. The next day, the girls plan on going to the beach, but a rainstorm prevents them. A young boy named Takashi is crying about the rain, so they invite him to play with them...
