Aya Nakanishi is one of the original three victims of serial kidnapping and killing by Gaku Yashiro. The other two victims being Hiromi Sugita and Kayo Hinazuki. Aya is a perfect student studying at Izumi Primary near Mikoto Elementary, and also attends Hamanasu private tutoring school.


She became a target as she always spent the hour before cram school alone. She befriends Satoru's friends, which prevented her death.

She plays piano. She hates going to cram school because she can't hang out with her friends. She likes songs like "The Entertainer" by Scott Joplin and seemed to be put off when Satoru didn't know what it was. She loves playing piano and reading, but feels like Shakespeare is too hard to understand. Her parents want her to play piano and read Shakespeare, even though she's only in Elementary school. She's described to be bright, friendly, and likeable. She's close to her parents.

After she recognizes that they're the ones who play in their hideout across the river, she says that it's childish. Kazu defends it, saying that it's a "man's dream" and telling her to come there when she's bored.

She goes to cram school between 5 and 6:30 on Tuesdays to Fridays. One day, she went to the hideout and talked with Kazu, whom she had a crush on; she was attracted to his manliness. He began walking her home from school.
