Yuuko Ozawa

Yuuji Itadori's classmate from middle school. At the time, she was short and overweight, not Yuuji's type, but he mentioned her as his favorite girl because she had neat handwriting and ate fish neatly. She had a crush on him and even took a photo with Yuuji at their middle school graduation. Upon entering high school, she moved from Sendai to Tokyo, and due to the stress of changing environments, she grew taller and lost weight.

After the Yaso Bridge incident, she coincidentally met Nobara Kugisaki and others, and after seeking love advice, she reunited with Yuuji. Even though she had slimmed down and looked completely different, Yuuji recognized her as Yuuko Ozawa. Although she never confessed her feelings to Yuuji, she exchanged contact information with Nobara when they parted ways.
