Blue Lock, created by Muneyuki Kaneshiro and Yuusuke Nomura, is one of the most popular manga series in recent history. The series has been serialized in Kodansha’s Weekly Shonen Magazine since August 2018 and has rapidly gained a dedicated following through its intense depiction of football.
The Blue Lock manga was originally believed to be on break this week, with chapter 303 scheduled for next week. However, in a surprise to fans, the latest installment has continued on its regular schedule, with the new chapter releasing on May 21, 2025, at 12:00 a.m. JST. This translates to a May 20, 2025, release for most international countries.
The recent chapters of Blue Lock have been among its most exciting, with the Neo Egoist League concluding and the shocking elimination of Seishirou Nagi. Chapter 303 marks the beginning of the latest arc of the story as well as the purpose behind Jinpachi Ego’s project.

Blue Lock chapter 303 begins the journey towards the U-20 World Cup
Chapter 303 starts by featuring Hirotoshi Buratsuta, the chairman of the Japan Football Union, celebrating the economic benefits and profit derived from the Neo Egoist League and BLTV. While praising the spirit of capitalism, Jinpachi Ego appears, having been summoned.
Upon seeing Ego, Buratsuta started by praising his efforts, but soon began complaining about Nagi’s elimination. With the social media outrage about the prodigy’s loss and his money-making potential, Buratsuta told Ego to bring him back.
However, Ego shot him down, explaining how he was determined to lead Japan to victory and that he was the god of the project. The scene then shifts to the U-20 World Cup conference room, where Anri explains the goal of creating Project Blue Lock to reporters. After emphasizing the first two phases, she spoke on how the U-20 World Cup was phase three.
Set to be hosted by Japan, this tournament would be attended by 64 countries, including powerhouses such as France, led by Julian Loki, and Germany, led by Michael Kaiser. She reaffirmed their goal, which was victory. Back at Ego’s meeting, Buratsuta lashed out at Ego, explaining how he was in charge and demanding that Nagi be brought back.
Ego replied by saying he would quit if that happened, and that the 23 players he selected would not include Nagi. Left with no choice, Buratsuta threatened Ego, saying he would be fired if Japan didn’t win the U-20 World Cup. Ego replied that that was his plan anyway, and his wish to make Japan the center of football.
In the press conference, reporters and players were getting excited about matchups between individuals such as Loki and Rin Itoshi, and Kaiser and Isagi. With the popularity generated by the Neo Egoist League, this U-20 World Cup was going to be on the level of the real World Cup itself. Finally, Isagi was called up to speak as the representative of Blue Lock.
The protagonist, having manifested his egoism, confidently declared that they would win and that he would personally make the U-20 World Cup the hottest place in the football world. With 47 days left until the tournament, the chapter ends with a look at Nagi, playing games at an arcade with lifeless eyes.
Why the U-20 World Cup has the potential to be the Best Blue Lock Arc
The U-20 World Cup will mark the first time that the main cast plays against foreigners in a setting outside of Project Blue Lock. While they had interacted with talented international players in the Neo Egoist League, this was still only a step in their training, meant to polish their skills and perfect their egoism.

The U-20 World Cup will be the biggest stage of all, where their efforts will finally have to bear fruit. With the grudge Isagi has developed against Kaiser and Loki, and the eyes of the entire world on Japan, a new level of excitement will likely be unlocked.
Additionally, since Nagi has now been eliminated, fans will keep looking forward to ways in which he could return. The start of this new era is what Blue Lock has been building up to so far, and with the upcoming matches carrying the highest stakes in the series, there is little doubt that this could be the best and most significant arc in the story.
