Uchika and Connie's first meeting is changed. In the anime, Connie is alone at a badminton academy, while in the manga Uchika visited the orphan Connie who was staying with an old woman. In addition, the manga Connie didn't know about badminton until Uchika taught her. Also, because Viggo is cut from the anime, she still meets with Uchika even as a teenager.
