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.

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.

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.

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".

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?

The game has reached a fever pitch and some of the players are about to break. Can Kise keep up copy of Aomine or will Aomine finally be able to go all out.

Up next is Seirin against Kirisaki Daiichi. As usual, Kirisaki Daiichi plays dirty, on offense and defense, trying to injure the opposing players. However, Kiyoshi still pushes on and gets his spirit really burned up, but while he's fired up Hyuga can't seem make any of his 3-pointers. Will Seirin get over this extremely rough matchup?

Seirin managed to break free of Kirisaki Daiichi's 'spider web'. However, the game is still not over with Hanamiya having another card up his sleeves. Will Seirin still get their berth at the Winter Cup or is it over for them?

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.

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

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".

With only 10 minutes left, Seirin is in trouble. Kagami has run out of gas and Midorima shows no sign of stopping. Kuroko is back in the game with a new, but dangerous pass.

Touou Academy has not stolen the game like expected. If they can’t break away, Kise will finally reach full potential.

With Kuroko on the court, Seirin's team spirit has never been higher. Using his new invisible drive he is able to successfully take on Midorima. Using the same approach on Takao, the two teams are tied after a Hyūga 3 pointer. After a fierce battle, it all comes down to 2 free throws from Kiyoshi (caused by Midorima fouling him). He scored one of his shots, but his legs didn't hold out on the second. It hits the rim of the hoop, but luckily Kagami catches the rebound. In the final seconds of the match, Kagami and Midorima are engaged in an aerial battle. Will Kagami score, or does Mimorima have enough strength to stop the dunk?

Seirin leads by 5 points going into the 2nd half, and Kirisaki Daiichi executes their trap, in which Hanamiya gets his steals with 100% accuracy, and Seirin just has fallen under this trap. Kuroko suggests the team to take a gamble of trust in each other in order to break free of this trap. Will Seirin get their ticket to the Winter Cup?

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?

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.

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.

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?

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.

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.

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.

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.
