1. Mysterious Summer Festival

Akira, Mikoto, Kouhei and Ayuko go together to the summer festival. As Kouhei and Ayuko go off together, Akira and Mikoto are left on their own, but get separated in the crowd, with Mikoto being led away by a mysterious masked girl. As Akira searches for her, he comes across a strange tent where Mikoto is found tied up. Akira is then challenged by her kidnappers to pull a rope to free her, pulling the wrong one causing her to fall. Believing in their bond, Mikoto drools down the rope she is tied up against, allowing Akira to deduce the correct rope to pull. After Akira frees Mikoto, the kidnappers and the tent mysteriously disappear and Akira and Mikoto find themselves at the shrine, where Mikoto gives Akira a red string bracelet.
