Aya Nakanishi

Aya Nakanishi is a perfect student studying at Izumi Primary near to Satoru's primary school, and is one of the original victims of serial kidnapping. She became a target as she always spent the hour before cram school alone. She befriends Satoru's friends, which prevented her from being kidnapped.

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 seems to be put off when Satoru doesn't know what it is. She loves playing piano, 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 reconizes 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.

She attends Hamanasu private tutoring school.
