Yuka Mizuno

She is seen in corporate clothing watching the match between Yokohama and Osaka, in which Sora partook in together with Kanzaki Masaomi. Yuka was Sora's classmate in high school. One day, she decided to confess to an upperclassman and was rejected. On the same day, her class chooses a song for their Festival Choir's show. Unfortunately, the chosen song was "Song of Memories", a song that the upperclassman who rejected her liked. Not wanting to sing due to the painful reminder of the song, she volunteers to be the conductor, but performs badly. She manages to pull herself together when Sora suggests "overwriting" her image of the song. The performance of the class became a hit, and her short solo was well received. After a while, she moves to another town, but not without telling Sora that she will keep watching him to see if he can really become 1/11 of the world's best soccer team. In the end, it is shown that she successfully "overwrote" her image of the song.
