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".

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.

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?

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"?

Barou joins Isagi and Nagi's team, already causing quite a stir with his conflicts with Nagi. Isagi is trying to see a way to mediate these two, which will be very complicated.

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?

The tryouts are complete, and Isagi is chosen for the starting lineup. But Shidou is nowhere to be seen... It turns out Sae has picked him to join the U-20s. Meanwhile, Ego begins the final training camp, where he discusses the secret of "flow."

The exhibition match between Blue Lock and Japan's U-20s has finally kicked off. The first play Bachira and Isagi set up has been swiftly shut down by the U-20s' captain, Aiku, and Isagi finds a new challenge in him.

Isagi realizes that the conclusion of the match is in his and Naruhaya's hands. However, how will he go about beating Naruhaya? This will be a game that will not depend on genius players, but on "mediocre" players.

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...

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?

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.

Isagi is chosen as Team A1 along with Nanase and Hiori to play against Team B1, which includes Karasu, Otoya, and Chigiri. While Isagi struggles to find a way into the game, Chigiri and Hiori demonstrate their worth.

Isagi looks back and analyzes what he did when he scored a goal on reflex. Then, when the second match begins, Reo finds his new playstyle: Chameleon.

Rin and Sae's sibling match goes to Sae as he takes the ball. But Niko, Karasu, Otoya, and Chigiri set up another goal chance, and Rin scores despite shooting on his non-dominant leg. At 1-2, the U-20s are finally ready to go all out.

Isagi, Bachira, and Chigiri's families are happy to see their sons on the field. Meanwhile, we get a glimpse of what transpired between Rin and Sae. Sae is about to quit the match, but he decides to stay when Shidou is thrown into the fray.

The match continues to leave Team Z scared of Nagi's abilities. However, one of the members is not scared, even though they are facing a soccer genius...?

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.

The Z team has only one game left to play, and it will decide the future of its members. While everyone seems to be nervous about the kickoff, Isagi is trying to find a way to score goals without anyone's help.

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.

Team Z launches a final counter to try and win against Team V. Isagi is trying to find the last piece he needs to crack the formula to become a goal machine.

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.

Seeing how incompatible Rin and Shidou are, Isagi hopes to take advantage of it. However, his physical abilities are not enough to get him where he needs to be. Then, Hiori suggests that Isagi does the thinking "on reflex."

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.

When Itoshi Sae scores the first goal of the match, the crowd goes wild, making it clear to Team Blue Lock that they're here to watch Sae. Rin changes the strategy and Nagi makes the memorable first goal for Team Blue Lock.
