Akari Shinohara

篠原明里

Takaki's best friend in elementary school. She wanted to go to the same junior high school as Takaki, but because of her parents' jobs, she had to move to Tochigi after graduating from elementary school. She and Takaki keep in touch with letters.

Later on due their distance and time apart from each other, these letters ceased to be exchanged.
