Regatta: Kimi to ita eien(2006)

Regatta: Kimi to ita eien is a Japanese anime series following Makoto, a talented university rower haunted by guilt after a tragic accident claims his best friend's life. Convinced he's responsible, Makoto abandons the team—until his teammates and fellow rower Misao convince him to return. Driven by a renewed passion for rowing and Olympic ambitions, Makoto throws himself into brutal training and competition. The series explores the emotional weight of elite sport: the sting of rivalry with teammates, the complications of love and friendship, and the hard lessons that come through dedication and loss. As Makoto pushes toward his dreams, he discovers that regatta demands far more than physical strength.
