Nanako Ohara (大原 ななこŌhara Nanako), Miss Bono in the Vitello and Phuuz dubs, is the college girl with whom Shin-chan is in love. She first appeared on in episode 175a "My True Love" (オラの本気の恋だゾ). The first time they met was when Shin-chan was strolling in the neighborhood and got something in his eye. Nanako took it out for him. Since then, they have kept in contact. Nanako is the only girl that is unruffled by Shin-chan's behavior, and the only one Shin-chan tries to behave for, even being shy and blushing around her. She dreams of being a kindergarten teacher.
Her father is a novelist and famous author of many popular books. He disapproves of Shin-chan's love for his daughter though they both band together in keeping an eye on her. Her best friend is Shinobu Kandadori, with whom she concurrently lives in a city flat.
In the manga her hair color is brown, but in the anime it is black.
She is named after Nanako Matsushima.
