The Team Royal came together under Kurisu (played by Satoshi Tsumabuki) and Koichi (Ren Meguro), aiming for the Arima Kinen the year after the next. After Ryujiro (Mahiro Takasugi) steps aside, Shohei (Shogo Ichihara) becomes the team’s new main jockey and takes on the autumn G1 racing season. However, just as things seem to be going well, Shohei gets caught up in an unexpected and serious problem. Meanwhile, Nobuyuki (Taishi Nakagawa)—Koichi’s rival—aims to win the Arima with an undefeated Triple Crown, a feat even his father, Shiina (Ikki Sawamura), could never accomplish. A series of sudden troubles threaten to crush Team Royal’s dream of racing in the year's Arima Kinen they aimed for. Even so, Kurisu and Koichi fight desperately to protect their team and keep their shared dream alive.
Kurisu has always admired his father, who runs a tax accounting firm, and dreamed of working with him one day. To broaden his skills, he joined a major tax firm, but a professional setback left him disillusioned. His life takes an unexpected turn when he meets racehorse owner Sanno Kozo, reigniting his sense of purpose.
