Rin chooses to add Isagi to his team, and together with Bachira they pass the second selection. Waiting for them on the other side is a 5-on-5 match against a team of world-class players. Thanks to Isagi, Bachira, and Rin's coordinated play, they manage to score the first goal, but they soon find themselves overwhelmed by the opposing team's superior skill and ability. Despite this, they desperately keep fighting until the last second, unleashing their own "egos." As a result, the "Blue Lock" project, aiming to produce the world's greatest striker, enters a new phase.
Bachira sheds his ideal of the "monster" and finally awakens his own ego. Until now, Bachira had been seeking someone to follow, but now he charges forward towards his own goal, finding in Isagi a companion who trusts in his ego. Isagi performs a decisive cut, but the ball made its merciless way to the victor's side... The time for the ultimate showdown has arrived, making sparks fly as the eight egoists clash. Which team will emerge victorious in the second selection's "Rivalry Battle"?
The thrill of finally finding the "monsters" with overwhelming talent became short-lived, as Bachira realizes he's being left behind in the battle between Isagi and Rin. Meanwhile, the game is reaching its final stage, with a fierce back-and-forth battle led by the wild card, Barou. As Isagi takes his skills to the next level under extreme conditions, Bachira is forced to confront his own "ego" amidst the intensity of the situation. Where will their newfound powers take them, and what impact will it have on the game's outcome?
Isagi captures everything that’s happening in the field to see its future, and Nagi controls the space. Their combination bursts, and their series of play lights up the fire in Rin. Rin’s dominating play that encompasses everything on the field, from the skills of all players, the ball, positioning and tactics gradually corners Isagi’s team once again. As chaos and ego clash, one man is covertly sharpening his fangs to devour the game dominated by Rin.
Isagi and his friends barely manage to win as Barou awakens as the "villain" of the field. In order to cause a further "chemical reaction", they take away the only player who showed their ego to "eat" themselves and advance to the force stage. On the other hand, Bachira, who is looking for an opponent for the next match with TOP3, sees through the existence of a "Monster" in himself during training with Rin, and faces his own "ego".
By understanding and enhancing each other’s weapons, Isagi and Nagi are drawing countless paths to the goal. In contrast, with Chigiri, who has further evolved, at the center, Kunigami and Reo find themselves struggling to keep up, and a back-and-forth battle unfolds on the field. Meanwhile, Barou, who should have been the king of the field, was left behind in the evolutionary chain because of his overpowering ego. Having been robbed of the leading role on the field by Isagi, Barou finally falls to his knees.
Isagi begins to realize that his former teammates made a great trio with Reo, making the best use of their own weapons. Now, he'll have to think about how he's going to get his much-desired "chemical reaction" with Nagi and Barou, if not, he won't be able to win. That said, the Barou remain not very cooperative...
The loss of Bachira on his team makes Isagi very anxious about what his future with Nagi will be like. To make matters worse, the situation is now even more complex: the ideal would be to go against a weaker team, but that would mean taking a weaker player too, which would make it more difficult to advance the next stages. So what are Isagi and Nagi going to do?
In this new stage of the second selection, the white team formed by Isagi, Nagi and Bachira will finally go against the top three in the ranking of the previous stage, running the risk of losing one of their three players if they lose the game. Still, the willingness to test their new skills against the top three is much stronger in the white team members. Will they be able to win this match?
With many dropouts, the "Blue Lock" project enters the second selection. A harsh second selection where former friends become rivals and former enemies become allies at a dizzying pace. There, Isagi meets Rin, the most powerful egoist ever, the younger brother of the genius Itoshi Sae, and the new Blue Lock ranking TOP ranker. Seeking further evolution, Isagi's fight advances to a new stage.
Each player unleashed their weapon and ego, and Team Z has caught up to a draw. They totally have the momentum of the game, but that has “awakened” Team V’s monster, Nagi. In the chain reaction to awakening, Isagi also learns to use his weapon and keeps fighting. The “heat” generated by the clashing of ego from both teams starts to affect Kuon as well.
Because of Kuon’s betrayal, Team Z is faced with a desperate situation of playing 12-on-10, with the opponent knowing everything about their weapons and strategies. Even under such a circumstance, Team Z never gives up on the fight, and Isagi continues to believe in himself. Inspired by their passion, Chigiri runs through the field at an incredible speed, his weapon he has sealed away. His ego rocks the match when they are losing at 3-4.
After the match with Team Y, Isagi's rank moved up, and he became the center of the team. The next match is against Team W, led by the Wanima twins. Their eye contact and impeccable combinations are hard to beat. They used to play in the same team as Chigiri Hyoma, and they use his past trauma to egg him on. Chigiri says that he joined Blue Lock to find a reason to quit soccer. Team Z leads the game with Kuon's play. Everyone's elated for the good start of the match, but Isagi feels something is off.
Isagi relies on "the smell of the goal," his raw instincts, to make a move, and it leads to the fierce battle of "reading" each other's hand with Team Y's playmaker, Niko Ikki. Isagi and Niko's battle as they both watch over the whole field and throw their ego at each other, brings them to the last one minute of the match. Can Isagi and Team Z beat Niko's final strategy, "One Time Kill Counter"?
Team Z was crushed by Team X, who centered the offensive play around egoistical yet skilled Barou. Responding to Ego's urge to "take up a weapon," the players discuss what their weapons are in preparation for the next match. However, Isagi struggles to identify what it is. Using "the smell of the goal" he felt in the game against Team X as a hint, Isagi and the others go against Team Y in the next match.
The first selection is the round-robin tournament of five teams of V, W, X, Y and Z in Building Five, with only top two teams being eligible to move forward. Isagi's Team Z, the lowest ranking team, plays against Team X. But because of the special rule that allows the top scorer of the team to proceed to the next section, the match turns into chaotic scrambling for the ball, regardless of the teams. It was Barou Shoei, Team X's formidable striker, who changes the flow of the game.
Isagi Yoichi, a first-year forward, loses his chance for the Nationals because he has passed the ball to his fellow player in front of the goal. That's when he receives an invitation for Blue Lock. It's a facility to train one world's greatest striker out of 300 high-school-aged forwards so that Japan can win the World Cup.
