Hiromi has spent three years becoming what her coach wanted her to be, and now the show asks the question that destroys her: what does she actually want? The animation doesn't flinch away from the cost of ambition, sweat reads as exhaustion, victories feel hollow, the romance between student and mentor becomes something the first series never dared to touch. By the end, you realize this wasn't a sequel about tennis at all; it was about two people who built their entire lives around each other realizing they might have built them wrong.

Three years of relentless training have turned Hiromi into Japan's junior tennis champion, but her greatest victory may be the one she hasn't won yet. When her coach is chosen to lead Japan's national team on a trip to America with its youngest players, Hiromi is picked to compete in an international tournament in New York. There she faces new challengers, and without her coach at her side she has to find the will to keep playing. What complicates her rise isn't just the competition waiting stateside. The bond between Hiromi and her coach has grown closer on a personal level, pressing against the line between mentor and pupil. This is tennis drama where dedication and emotion run side by side.
