Kira is eliminated from Blue Lock, and with that, the first day at the Blue Lock that promises to create the greatest center forward in the world begins in Isagi Yoichi 's life.

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.

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.

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"?

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.

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.

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.

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...?

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.
