Stage and Steel - Yoon Do-Jin
Every great story begins with a dream. For Isla Caldwell and her team, Royal Harmonix, that dream was music. From small stages to grand arenas, their voices carried them forward, one note at a time. It started with regionals, where they poured their hearts into every harmony, every crescendo, proving that they were more than just another choir from London. Victory tasted sweet, but it was only the beginning. The nationals awaited-set in the vibrant city of Barcelona, where the best voices from around the world would compete for a single prize: a chance to sing on the legendary Broadway stage in New York.
But Barcelona wasn't just about music.
It was a city of fierce battles-not just in song but in strength. As fate would have it, the Harmonia: International Singing Championship coincided with another prestigious tournament: the Sekai Taikai, the world's most elite karate competition. And in their hotel lobby, amidst the singers rehearsing scales and harmonies, stood warriors preparing for combat. Among them was Yoon Do-Jin, a skilled fighter from Korea's infamous Cobra Kai.
At first, Isla and Do-Jin seemed worlds apart-her world was melodies and lyrics, his was discipline and strikes. But in the chaos of competition, in the high stakes of victory and defeat, they found something neither expected: each other.
As Royal Harmonix took the stage, delivering performances that electrified the crowd, Cobra Kai was fighting its way through the tournament with raw determination. Their two paths ran parallel-until they finally collided. And when the world was watching, when pressure was at its peak, Isla and Do-Jin would learn that some moments-whether in music or in battle-were about more than just winning.
Because in Barcelona, under the bright lights, amid the roar of crowds and the thrill of performance, Isla Caldwell and Yoon Do-Jin would discover that the most powerful thing in competition... isn't just talent. It's heart.
