After the winter cup prelimenaries, Seirin had their rest at a hotspring. At the same time, Tōō Academy is there, it's a surprise for them that they will fight in the first round. Will Seirin be nervous or they will be filled with excitement?

Before the Winter Cup starts, Akashi summons the rest of the Generation of Miracles, along with Kuroko. Kagami also joins in and it is a bad first meeting between Akashi and Kagami. The highly anticipated match between Seirin and Tōō Academy starts, and who will take the advantage?

Seirin managed to keep on pace with Tōō Academy. However, things just don't go right when Kuroko has both his moves being stopped consecutively by Aomine. How will Seirin come back to the game?

Kagami managed to hold Aomine and put Seirin close to Tōō Academy. Only down by 2, Seirin seemed to be able to keep in pace. However, another crisis would soon happen. How will this hinder Seirin's chances of winning the rematch?

Imayoshi is able to immobilise Kuroko, and Sakurai manages to stop Hyuga's Barrier Jumper, both actions being instructed by Momoi. Aomine goes past Kagami and makes a 360 spin dunk at the same time. All 5 Touou players are now able to see Kuroko. However, this actually leads to a trap set by Kuroko, when Izuki goes past Imayoshi with a Vanishing Drive, something the crowd thought only Kuroko can pull off, and scores. Hyuga also managed to bypass Sakurai with a Vanishing Drive too, and scored. The revelation of Misdirection Overflow has pulled Seirin to within single digit difference. However, Imayoshi scores a buzzer-beating 3-pointer to put Touou's lead to 11, ending the 3rd quarter. Before timeout expires, Aomine did not pay attention as the rest of the players return to the court. 4th quarter starts, and Seirin starts off with Hyuga combining his Barrier Jumper and Kuroko's Misdirection Overflow to avoid Sakurai's quick defense and scores a 3-pointer, putting the difference back to 8. The real Aomine will reveal himself soon, so how will Seirin cope with the Aomine even more stronger than they have faced in the first half?

At this stage, stopping the stronger Aomine has become the priority for Seirin, if not the latter will lose the game. After slowing getting back into the game, Seirin suddenly could not stop the Aomine who has entered the Zone. However, Kagami has managed to stop Aomine and what will the battle of the aces be like?

An intense battle between the Aces of their teams, Aomine and Kagami, begins. Both never give in to each other and blocked the shots of each other. The other players on the court are very amazed at the battle of the Aces in the Zone, which makes their focus and reaction speed to be at their maximums. Kagami goes to drive past Aomine and scores a basket, to cut Tōō's lead to just 3, 95-98, with 41.5 seconds left. In the next possession for Tōō, Aomine found it difficult to drive past Kagami, but he quickly goes for a Formless Shot.

While the match between Seirin and Nakamiya South progresses, at Touou Academy's library, Imayoshi and Susa discussed about Seirin's possibility of winning the match while studying. Seirin indeed are in a difficult situation of beating Nakamiya South. Imayoshi said that Seirin have not given their 120% like what the players did against Touou, and they may have gotten a little overconfident as they have defeated Tōō.

Still unable to score against Murasakibara and the Yōsen team, Seirin resorted to Kuroko taking shots, and they are back on track in the game. However, Himuro has not played his ball yet, so will Seirin be prepared for it?

Aomine thinks that Himuro is good, although the latter had never appeared in a tournament in Japan. Back to the match, Himuro executes a superb fake on Kagami, then smoothly transitions to take a jump shot, to which Kagami and Hyuga cannot react to it. Before the match, Himuro said to Murasakibara that he wants to crush Kagami, and that being brothers with him is getting in his way to be the better basketball player.

With Murasakibara finally appearing on the offensive side, Seirin is slowly losing hope of having the chance to win against Yōsen and move onto the Finals. With the help of the Vice-captain, Fukui, Murasakibara catches the ball and dunks it, causing the hoop to break and collide with the ground, even further diminishing the hope of Seirin.

As the match continues in the fourth quarter, Yōsen keeps on maintaining its lead and with Kiyoshi out, the Seirin players face tough times scoring any points. Seirin starts to use the same full court 2-3 man-to-man defense like what Yosen uses, but Himuro and Murasakibara are easily able to overcome it. However, Kagami's spirit to win gets him into the Zone once again.After some time in the Zone, Seirin cuts down the lead to four points.

In the last minute of the fourth quarter, Murasakibara enters the Zone. However, Kagami had so much spirit to win that he exceeded his limits and used meteor jam, his new shot that he can use only in the Zone. He jammed the ball in, scoring the final point. However, Atsushi still had determination and went for his shot. However, Murasakibara could not jump and Kuroko blocked his shot, handing victory over to Seirin. Murasakibara broke down after the game, revealing that he actually loves basketball, which enabled him to enter the Zone. Kuroko also tells Kagami to reconcile with Himuro, which he does.

The final four of Winter Cup has finally been decided: Rakuzan, Shutoku, Seirin, and Kaijo. However, on the day of the semi-finals, Kuroko and Kagami both realized their basketball shoes were broken and hurriedly get on their way to buy new shoes. However, Kagami can't find shoes in his size! Thanks to Kuroko's suggestion, they seek advice from Momoi, and her reply is that he should use Aomine's shoes, as they both have the same shoe size. Of course, Aomine wasn't going to meekly hand a pair over, and they end up in a one-on-one with the shoes as the prize! Daiki quickly won but still offered the shoes to Kagami. Taiga grudgingly accepts and says that he'll take it for now but their competition isn't over yet. Taiga and Tetsuya rushed to watch the first semi-final match of the Winter Cup: Rakuzan Vs. Shutoku.

As the second half of the match between Shutoku and Rakuzan starts, Akashi uses his eye, it is revealed that Akashi was the one who found Kuroko's talent by using his eye on him, which meant that the eye can see potential of people, but it is said that in matches the eye is completely different, it predicts the future movement of the other players, thus nullifying both offence and defense of the other team.

Facing Akashi's Emperor Eye, which sees the future movements of the opponents, Shutoku looks like they had no hand to play. But the will to fight once again lights up within the eyes of the team members, and they face Rakuzan with the spirit of "unyielding tenacity"! Thanks to Midorima and Takao's trick play, they try to close the gap in one strong run, but to answer that, Akashi scores in his own goal to the shock of everyone around him. Against Shutoku, who bares their teeth without giving up until the very end, Akashi throws out words that show no mercy.

After the match Rakuzan vs.Shutoku, Rakuzan wins with the score of 86 - 70 against Shutoku. For the Shutoku team, it is a very huge defeat that even Takao and Midorima cried after the game. Kise, Kagami and Kuroko did have some short greetings before their match. The match started, how can Seirin stop Kise's Perfect Copy?

The battle between Seirin and Kaijo finally begins. Seirin tries to secure their victory by striking first, but Kise unexpectedly begins using his Perfect Copy at the start of the game, demonstrating his overwhelming strength.

The Seirin-Kaijo game was white-hot due to the battle between their ace players. With the defense and offense reversed now, Seirin goes on the offensive. As the last one to awaken, and one with potential comparable to the Generation of Miracles, Kagami was on his way to unleashing that latent talent. Kise felt that as a threat more than anyone else. That was why he definitely didn't want to lose!!

Kise's injury becomes worse. His coach orders him to step down the court for a while and rest until the last two minutes of the last quarter wherein he could use his Perfect Copy. Kagami's talents give way to Seirin having a 15-point gap in the lead with four minutes left in the game. Kise's frustration leads him to recover fast, determined to win the cup. Rico is surprised and realizes that Kise's Perfect Copy can now last until the end of the competition.

Kise recovers and manages to fill the 15-point gap. Kaijo becomes the lead with a score of 78-77. Seirin becomes restless and their moves become stiff as Kise's fast recovery and Kaijo's persistence to win makes the crowds cheer, putting Seirin under pressure. Kuroko devises a plan that requires time for observation in order to overcome Kise's Perfect Copy.

Kuroko finally finds a way to stop Kise, and Seirin wins with a deciding shot made by Kuroko. The episode ends with Kuroko telling a story about his past

Kuroko is first placed into Teiko's third string basketball team. However, after practicing everyday after school with Aomine, Akashi realised Kuroko talent as the "Phantom 6th Man." During a game between the third and second string, Kuroko proved himself and was upgraded to first string. But when he plays in a friendly game as starting player, he is so nervous he is subbed out immediately. The coaches are unsure if they should keep him on first string, but with Aomine's encouragement, they keep him on for one day. Now that Kuroko's nerves are under control, his help in the team is obvious and he is permanently placed on the first string bench.

Nijimura gives the captain position to Akashi because his father is sick. Akashi now becomes captain. The Teiko coach comes back. Midorima and Murasakibara gets into a fight, and Kuroko challenges them into a practice game. Then, Aomine and Kise get into a fight, but not a serious one. Akashi wants to get rid of Haizaki because he keeps skipping practices. Aomine plays a game, but he doesn't have fun and loses interest in basketball because he crushed the other team. Teiko goes to the National qualifiers, and Aomine meets his friend, while the face of Kuroko's friend is also revealed. Aomine ends up crushing his friend's team, and gets called a monster by his friend. Also, Kuroko's friend loses, and calls Kuroko, crying. The episode ends with Aomine sitting by the pool, a blank expression on his face.

The old coach advises to Aomine to keep playing basketball until he can find a worthy opponent. Teiko wins the National finals. The old coach collapses and the young one takes over coaching the team. The team individually undergoes rapid growth in power. Aomine leaves mid-practice and the coach gives him permission to skip practices, leaving Aomine in even more despair. After an act of insubordination, Akashi goes head to head with Murasakibara, and just when Akashi is about to lose, he switches personalities and crushes Murasakibara. Akashi gives the rest of the team permission to skip practice as long as they win matches. He later tells Kuroko who failed to convince Aomine that there is two of him.

Kuroko get's knocked unconscious in the game before the grand final, in which Teiko is set to play against Kuroko's friend, Shige's team. Kuroko regains consciousness, and since he cannot play in the game, asks Akashi to make Teiko play their best. Teiko, bored by scoring quotas, decide to play a new game. Kuroko gets to the match in time to see the conclusion of the game, with Murasakibara scoring the final goal for the opposite team in order to make the score read "111, 11". Devastated, Kuroko decides to quit basketball and visits Shige's school, where he finds out Shige has transferred and is going to quit basketball. Shige's friend tells him not to quit basketball, because he thinks Kuroko can melt their hearts.

Seirin prepare mentally for the grand final match of the Winter Cup. Kagami and Tatsuya finally properly reconcile. The teams from previous matches, including the teams of the Generation of Miracles come to watch the grand final. During the decider for 3rd place, Kise sits out of the match and Shutoku wins against Kaijo, 96 to 54, taking 3rd place. Rakuzan and Seirin warm up, and Akashi declares the winner will be Rakuzan. Furihata gives Kuroko a wristband filled with the team's thoughts. The game starts with Kagami taking the tip off. Kuroko fumbles a pass but Kagami manages to score the first goal with an impossible jump. And enters "the zone".

Kagami dangerously continues using up his stamina in the zone, Riko swaps Kuroko for Mitobe so that Kagami can focus on offence. Akashi pairs up against Kagami and Akashi takes control of the game until Mitobe's defense breaks the flow. Kagami exits the zone, and Kuroko re-enters the game. Kuroko is more visible than usual, which Akashi claims is due to his learning how to dribble and shoot. Disheartened, Kuroko is taken out of the match for one side pass, then put back in for the remainder of the first quarter. The first quarter is finished with a tie, 21-21. Kuroko is set to sit out the 2nd quarter to think of a solution. Meanwhile Rakuzan's Chihiro Mayuzumi reveals his ability to misdirect just like Kuroko, but with better base attributes.

Kuroko observes Mayuzumi's play from the sidelines. Seirin subs in first-year Furihata to lure Rakuzan, but he quickly gets fatigued after facing Akashi. Fukuda, a first-year, takes his place. Hyuga goes up against Rakuzan's Reo Mibuchi (who Hyuga admired in middle school) in a "Battle of the shooting guards", but loses. The same happens to Kiyoshi against Eikichi Nebuya. Another first-year takes Fukuda's place. One-by-one, Rakuzan crushes Seirin's players. Akashi demonstrates that he can also make alley-oops, finishing the second quarter with Rakuzan in the lead, 62-37.

Rakuzan vs. Seirin enters the third quarter. Seirin, not giving up, entrusts their scorers Hyuga and Kagami with all their hope. However, even that small glimmer ...

Izuki manages to interfere with Rakuzan's Kitari Hayama's five-finger-dribble offense, by predicting future moves and coordinating with Kuroko and Kagami. Kagami remains in the zone. Koganei faces Reo, and although Koganei doesn't manage to defeat him, Hyuga comes to understand how to beat Reo's three specialty shots (Heaven, Earth, Void).

Hyuga rejoins the match in fourth quarter and scores the first three, flourishing under the pressure and having worked out how to tell the difference between Mibuchi Reo's three shots, and the secret of "Void". Despite Kiyoshi's knee injury bothering him, he pushes back against his opponent Eikichi Nebuya. Akashi relieves control of the ball against Kagami who is going even deeper in the zone. However, Akashi has learnt how to enter the zone at will, reserving it for when Rakuzan is in trouble. His trigger being when he decides to abandon the rest of the team and use his own strength to win. Akashi enters the zone and scores on his own. Seirin calls a timeout with Rakuzan in the lead, 90-78. Seirin puts their faith in Kagami. In the audience, Aomine mentions that he suspects there is a greater zone within the zone. And that Kagami may need to open this second "door" to be able to beat Akashi.

Faced by Akashi's huge zone of defence, Kagami despairs, having reached the bottom of the zone, but seeing no way to open the "door". Kuroko suggests they give up relying solely on Kagami for now, and offers to take some of the burden. By watching and predicting Kagami's movement, Kuroko becomes Kagami's "eye" and is able to intercept Akashi. Although stunned, Akashi catches up and attempts to stop Kagami, but is intercepted again by Kuroko. One last time, Akashi attempts to intercept Kagami's dunk, but Kagami, with his teammates supporting him, manages to crack open the "door" within the zone and scores. Akashi misses a goal, and has fallen out of the Zone. A voice inside Akashi starts telling him to give-up. Rakuzan calls a time out with 5 minutes left in the game, and the score 92-90. Just as Rakuzan's coach is about to sub Akashi out, Mayuzumi chastises Akashi, asking rhetorically "Who are you?", which triggers an internal dialogue with his other self. Akashi strove for victory in order to keep his team together and in his weakness he created his other self. But then he started playing for victory itself, forgetting why. Now, his two selves appear to merge, or perhaps switch places, and, echoing his words to Kuroko in middle school, aloud he declares himself "Akashi Seijuro".

Akashi starts supporting the team by setting up perfect opportunities which also boosts their morale. The watching members of the Generation of Miracles recognise Akashi's old self. Seirin still manage to score, but Akashi enters the zone again and Akashi's support draws out his team members' potentials, making them enter an imperfect version of the zone, possible because they are members of the "Uncrowned Kings". Kagami is the only one who can stand against them, but reaches his physical limits, and exits the zone. The rest of Seirin are also exhausted and Seirin has no more time outs left. Suddenly, Kuroko's friend, Ogiwara, cheers from the audience, bringing Kuroko to tears. Aomine, Kise, Midorima and other past opponents adds their cheers, and the crowd starts to chant for Seirin. With the Rakuzan in the lead, 103-96 and 2 minutes left in the game, Kagami talks with the team, and manages to fully open the "door within the zone", unveiling the "True Zone", which is team play at the speed of the zone (possible because of the bond between the team members). Aomine realises that the person in front of the "door" is not a gatekeeper, but Kuroko, leading the way to team play. Seirin manage to score a two-pointer, but Akashi counters with a two pointer, and is not going to allow Seirin to win that easily.

With 40 seconds left in the game, Rakuzan is in the lead, 105-98. Kagami scores with 27 seconds left. With 17 seconds left, Izuki is the only one not fired up, deliberately trying to keep calm and use his head to catch Rakuzan off-guard. He predicts that Rakuzan will take a shot and steals the ball, making a perfect pass to Hyuga. Hyuga forces a foul as he scores a three and is allowed a free throw. Hyuga's shot rebounds and Kiyoshi uses his last strength to take it. With three seconds left the ball is passed to Kuroko, who goes to shoot. Akashi defends but Kuroko states "I am the shadow", and Kagami does one of his impossible jumps to dunk and Seirin win, 105-106, winning the Winter Cup. Akashi experiences his first ever loss, but is thankful to Kuroko and congratulates him with tears in his eyes. Some days later, Seirin see Kiyoshi off at the airport, as he is going overseas to get a surgery for his knee. Meanwhile 3rd years from Seirin's opponent teams are studying for college, while their teams appoint new captains and prepare for the next season of Basketball. Seirin return to school to practice but Kuroko is late. Kagami is sent to find him, and Kuroko explains that he was getting a photo from Momoi. As Kuroko and Kagami head back to practice, Kuroko's locker opens to reveal the photo- a team photo of the Generation of Miracles reunited.
