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.

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.

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.

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.

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

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?

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".

Kuroko has rejoined the game in the final moments, but it seems that one of the players has him figured out. Seirin is playing hard, but if they win, will they have the strength to play a 2nd game

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.

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.

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.

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?

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?

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?

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?

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.

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?

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 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?

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 is holding their own against Shutoku, but in the 2nd half Midorima and Takao’s abilities are unleashed, shutting down Seirin’s game completely

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?

The training camp is over and everyone has learned something about themselves. But the team is not ready to leave yet, as there is a game happening: Kaijo vs Touou, Kise Ryota vs Aomine Daiki.

Kise and Haizaki face each other head-to-head for the right to advance to face Seirin. At first it seems that Kise and Haizaki have the same copy ability as Haizaki is able to start duplicating Kise's teammates moves. However once Kaizaki has duplicated a move, the original user seems to be unable to use it. Kuroko reveals that Haizaki uses psychological warfare against his opponents. While he copies the moves of the individual, he also alters the timing of the move. When the original user tries to do the move again, they try to do so with the new timing and ultimately fail. Kise and his teammates fall further behind as the second half begins. Can Kise find a move that Haizaki can't use and somehow manage to turn things around, or is his team headed for certain defeat?

Due to the rush of the matches, there is no overtime, hence the match ends with a tie at 104 apiece. On the other side, Kirisaki Daiichi defeated Senshinkhan 108-70, but it is said that the former won with unfair measures. Outside the locker room, Kagami overheard the fiery conversation between Hyuga and Kiyoshi and then at night, he asked Hyuga more about it. It was actually Kiyoshi's final chance of playing high school basketball, despite only being in his 2nd year. Flashback to 1 year ago, the story goes on about the formation of Seirin's basketball club, Hyuga's real feelings about basketball in high school and Kiyoshi's determination to set up the basketball club.

The street ball game gets called off due to heavy rain. Meanwhile, Momoi reveals that Aomine did not play in the Inter-High finals due to injuries that led her to request the coach to drop him to the bench. She also revealed the reasons why Murasakibara and Seijūrō Akashi from Rakuzan High, did not play as well. Later on, Kuroko shows Momoi his newest technique which if it is refined well, no one can ever stop 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.

The only thing you can do is pick yourself up and move on. Some can move on faster, while others wallow in their own darkness. A new beginning and an old friend is what needed to pick the team back up.

After defeating Yōsen High, Seirin is interviewed for Basketball Monthly. After the interview Kagami heads outside to visit with his old friend, Tatsuya Himuro, and Alex, but instead of being able to resolve their differences he runs into one Shōgo Haizaki of Fukuda Sōgō Academy. He is trying to flirt with Alex, making Kagami mad, but before Kagami can act Kise arrives on the scene and reveals that Haizaki was a starter on the Generation of Miracles team before he arrived. Kagami heads back in to ask Kuroko about this news only to find out the final quarterfinal will feature a showdown between Kise and Haizaki, with the winner moving on to face Seirin in the semifinals.

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.

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.

After their win over Shinkyo, Seirin goes on to crush their next few opponents. Realizing too much confidence is brewing, the team is taken to watch a Shutoku match. After seeing how Shutoku, one of the three Emperor teams of basketball, dominates their opposition, the team realizes they have a long way to go if they are to improve and contend for the title.

Serins first opponent in the inter-high tournament is Shinkyo high, a middle tier school until last year. With the addition of a two meter tall, 87 kilogram player from Senegal, Shinkyo is a new threat to Serins championship hopes.

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.

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.

Hyuga officially joins the basketball team, and so does Riko. They win their first matches and entered the final match against Kirisaki Daiichi and Hanamiya Makoto, a Crownless General like Kiyoshi. In one of the last plays Hanamiya purposely injures Kiyoshi's leg. Seirin lose the subsequent matches and are eliminated from the Nationals. Hyuga is determined to lead the team next year to be the best in Japan, which currently they are on course to be, and Kirisaki Daiichi is next in Seirin's way.

Kuroko devises a plan that requires time for observation in order to overcome 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.

Before anyone can become an official member of the Basketball Club, they first must do display courage. Afterwards, a surprising guest appears on the school grounds with a shocking offer.

Seirin first takes on Senshinkan High, who the former has lost twice to in the past 2 years. Seirin takes the game 78-61. Shutoku also took their first game 123-51 against Kirisaki Daiichi, which the first string players did not even play, and instead are watching the Seirin game, confident of winning the next 2 games. Kiyoshi meets Hanamiya Makoto from Kirisaki Daiichi, also one of the Uncrowned Kings. In their previous match-up, Kiyoshi got injured because of Hanamiya. Seirin-Shutoku match is up next. Midorima keeps on getting blocked by Kagami. It is revealed that Midorima wants to tire Kagami by making Kagami jump to block when Midorima is about to shoot.
