«Я встречал множество самородков. Но никого, подобного ему. Он не просто гений. Он даже не человек...» Рю Пэксан — главный хулиган в школе, выходящий победителем из любой драки. Инчжэ — сын профессионального боксера, мечтающий пойти по стопам отца. Ю — тихий парень, который день за днем молча сносит побои от одноклассников, даже не пытаясь дать сдачи. Кто же из троих школьников станет новым — и последним — учеником Кея, легендарного тренера по боксу, который за свою карьеру воспитал пятерых чемпионов мира?..

AN INSURMOUNTABLE WALL OF DESPAIR! IS NATURAL TALENT THE BE-ALL, END-ALL...? After landing Baeksan in the hospital, Yu finds himself taking up K’s offer to join his gym. The legendary coach sweeps Yu away and gives him a new hairstyle, a new place to live, and a new become king of the boxing world! But K’s other prodigies aren’t too keen on a clueless, scrawny newbie receiving all their trainer’s attention… Still, Yu may have bigger fish to fry―his first professional fight has been set, and he’s facing the infamous “rookie killer,” John Taker. Can Yu’s innate genius hold a candle to years of experience and underhanded tricks?!

THE MONSTER VERSUS THE WILD BEAST! WHO WILL COME OUT ON TOP? Every boxing fan is raring to see the matchup between Yu and Qasim, the two inhumanly strong rookies setting fire to the professional scene. And Qasim himself won’t be satisfied until he’s crowned champion atop a throne of pummeled opponents―Yu included! But Qasim’s not the only one with his sights set on K’s new prodigy. The number one light weight boxer, Jean Pierre Manuel, is enamored by the perfection he sees in Yu. Just how far is he willing to go to reach that same height…?

ITS GRUESOMENESS MAKES IT ALL THE MORE BEAUTIFUL… BEHOLD, THE PINNACLE OF BOXING TECHNIQUE!! The highly anticipated lightweight championship fight continues! With Yu landing a shocking blow and Jean Pierre knocked down, everyone is left dying to know―can Jean defend his belt, or will Yu win his first world title? Meanwhile, watching this all unfold is Yu’s old schoolmate Injae, who is making his own foray into professional boxing. Injae’s got the spirit and resolve, but does he have the prowess to win his debut match…?

A MATCHUP FOR THE AGES! And the lightweight world champion is…Yu! With one weight division conquered, K sets his protégé’s sights on the next target: junior welterweight. This inevitably pits Yu against Yuto Takeda, a tenacious boxer who earned his belt through nothing but hard work―the antithesis to Yu’s natural talent. Will Yuto prove to be the first force powerful enough to derail Yu’s unstoppable path of destruction…?

The battle for the Junior Welterweight belt begins as Yu and Takeda duke it out! However, a battle of skill quickly turns into a battle of heart as Takeda’s tenacity makes it difficult for even Yu to keep him down. Meanwhile, Yu’s explosive rise has piqued the interest of the infamous Santorino brothers, a duo that is willing to go to extreme lengths to maintain their status as middleweight champions. Just what ominous opposition awaits Yu in his future...?

Yu veglia su Carmen ricoverata in ospedale e K gli propone di vendicarsi sul ring. I due avversari si ritrovano alla conferenza stampa prima del match. Contrariamente alle aspettative, è Fabrizio a cadere nella provocazione dell’avversario e a infuriarsi! Santorino si troverà ad affrontare uno Yu agguerrito come non mai... e verranno svelati i retroscena della vita dei due fratelli!

Fabrizio è stato sconfitto, sfuggendo per un soffio alla morte e tornando sano e salvo tra le braccia della sua famiglia. Dopo aver conquistato sette categorie di peso con la sua potenza distruttiva, Yu si trova ad affrontare Viktor Grigoroyevich, il campione mondiale dei pesi massimi leggeri. Con quale arma affronterà questo pugile dal bizzarro taglio alla moicana, un “fortunato” che punta tutto su una sola mossa, dotato di un pugno micidiale?!

Aron Tide rifiuta il match contro Yu e sceglie di ritirarsi. Tuttavia, K non intende lasciarlo in pace e continua a imporre a Yu allenamenti terribili, come se fosse certo del ritorno di Aron. Mentre questi, intanto, trascorre un periodo felice e spensierato con la sua famiglia, gli si para davanti Carmen, che lo aggiorna della situazione e gli chiede di acconsentire alla sfida con Yu...

L’arena si tinge di follia. Con il round decisivo alle porte, Aron e Yu rinnovano con i rispettivi secondi la propria determinazione a combattere e si rimettono in piedi. Sono entrambi giunti al limite fisiologico, ma al termine di un cruento scontro sferrano contemporaneamente il colpo decisivo... Chi dei due finirà al tappeto?! E cosa farà J, che non distoglie lo sguardo da loro...?!
