REACH OUT AND GRASP GREATNESS. Jungle Pocket, known to her close friends as "Pokke," is a free-spirited Umamusume who has proven her dominance in the freestyle racing scene. Overwhelmed by Fuji Kiseki's majestic performance at a graded Twinkle Series race, she resolves to take on the Twinkle Series herself. Shortly after joining the Umamusume training school Tracen Academy, Pokke comes under the wing of Tanabe, a veteran trainer who fostered Fuji Kiseki's talent. Together, they aspire to dominate the Triple Crown series, a set of three races that can only be attempted once in a lifetime.
