Episode 2: Monster

At a Japan Football Union meeting, Anri Teieri insists the nation will never lift the World Cup on its current path, brushing off Hirotoshi Buratsuta's mockery and staking everything on Jinpachi Ego. Back in the facility, Kira rages that a two-minute tag game has ended his career, but Ego breaks it down: the arena matches a penalty box, where most goals are born, and a striker who cannot operate there has no gift. He notes that a player touches the ball only around 136 seconds across a full match, so Kira's refusal to gamble on the final second exposed him. Isagi, still buzzing, asks why Bachira handed him the ball; Bachira answers that results are all that matter here, and he trusted Isagi to strike.

The eleven survivors of Room Z become Team Z, teammates who will sometimes turn on each other. Days into training, Isagi sees Raichi outrun him and Kuon outjump him, and the cafeteria doles out side dishes by rank, leaving him with natto as number 299. Unable to sleep, he trains at night with Bachira, who describes a monster inside him that screams for goals, the same instinct he senses in Isagi. A fresh fitness ranking bumps Isagi to 274.

Ego reveals the compound's layout: 25 teams lettered B through Z across five buildings, with higher ranks earning better food and facilities. Meanwhile, reporter Shusaku Nihei interviews Sae Itoshi, a Royale prodigy back from Germany, who dismisses Japan's national side as weak and says no domestic forward is worthy of his passes.

Ego announces the First Selection, restricted to the 55 players housed in Building 5. The five teams there face one another, and only the top two advance to the Second Selection. When Team Z bickers over positions, Ego tells them to rebuild football from nothing, since the game began with strikers alone. Anri frames the whole project as the death of old Japanese football, arguing the country needs one hero rather than teamwork so that new tactics evolve to stop him.

The public unveiling of Blue Lock draws media outrage over sacrificing 299 careers for one, but Anri holds firm. Sae Itoshi, intrigued, chooses to stay in Japan and watch what kind of fool the experiment produces. Team Z then steps out to open their campaign against Team X.

The episode belongs to the Introduction Arc and introduces Chaos ga Kiwamaru as opening theme and WINNER as ending. The Additional Time skit, "Lost in Prison," has Isagi and Bachira forget which room is theirs after late training; Bachira flings doors open until Isagi finds it on the map, only for Bachira to declare the monster inside him can no longer hold it.
