In Carmon Kingdom, humans and monsters coexist peacefully, and racing these creatures on specially built karts has become the nation's obsession. Young Jin from a quiet village harbors big dreams of winning the prestigious Monkart championship, a path that promises glory and a chance to become a knight. Everything changes when a coup tears through the kingdom. Commander Destro seizes power and hunts down Princess Sena, forcing her to flee into the countryside. By pure chance, Sena crashes into Jin's life just as an ancient seal shatters, releasing Draka, a legendary dragon monster bound within his family sword. Stripped of their normal lives, Jin and Sena find themselves racing across dangerous terrain with Draka and other captured monsters, one step ahead of Destro's pursuing forces. What started as a competition becomes a desperate fight for the kingdom's survival. Fast-paced action blends with genuine stakes as unlikely allies discover that the monsters they race might be the only weapons capable of stopping tyranny.
