One Last Bloom (2023)

For the first time in four decades, Jinichi departs from America and makes a return to his home country of Japan. There, by chance at a bar, he encounters Shogo, a young boxer whose heart’s been broken after an unfair call cost him a match–the same unfairness that resulted in Junichi’s loss. The two pair up, aiming to fight at the World Championship, where they will give all that they have to prove themselves.
