Kazumi Endo  

, 遠藤一美

The soccer club's manager is responsible for supporting the team and keeping fans at bay from them. Although Kazuhiro had feelings for her, she was more interested in Toshi. This resulted in a rivalry between Toshi and Kazuhiro over their affections for her. However, it seems that Toshi did not view Kazumi as his love interest and may not have been very invested in pursuing a relationship with her.
