Another one of Ayumi's friends, Nao is somewhat envious of Kei's attention. Along with Koyoi, she stops walking home with Ayumi for fear of Misao. She is in her second year of middle school.

Being a member of the art club, she came to admire the artist who made the painting of a Sakura tree, Renjou Yukito, and after meeting him, asked him to assist her in making her own painting; however, upon his graduation, he left Japan, leaving her broken hearted. When she learned about Hiroyuki Sogabe's feelings toward her, she became close to him.
She shares a strong resemblance to Misuzu Sotomura, a character from another of Kawashita's work, Ichigo 100%.
