The girl, Akane Takigawa, apologizes to Ko for the construction noise. Later, Ko tells Azuma he does not know whether Akane really looks like Wakaba would now, because in his mind Wakaba is still in fifth grade. Mizuki invites Aoba to a summer festival the next day. Ko dreams of going to the festival with Wakaba, as she promised before she died, then of running to meet Akane at the Takigawa's soba restaurant. The next day, the anniversary of Wakaba's death, Aoba tells Ko to report his tournament result to Wakaba when he visits her grave. On his way back, he meets Akane wearing a yukata similar to Wakaba's. On her way to Wakaba's grave, Aoba sees them walking together and asks Mizuki if ghosts grow up. At the festival, Akaishi also sees them and asks Nakanishi the same quesiton. Ko and Akane meet her parents at the festival, and after parting with them, Ko meets Momiji, Ichiyo, Aoba, and Mizuki. When Aoba asks where his companion went, they begin to squabble but suddenly stop when the Tsukishimas see Akane at random through the festival crowd.
