Blue Lock 321: Isagi’s Revenge and the Beast of Destruction

The U-20 World Cup has been completely dominated by Japan, thanks to the explosive start of the second half. Rin Itoshi, having awakened his new “Beast of Destruction” form, has scored an incredible goal, putting the team up 3-0. With the game now a complete wash, Nigeria is on the brink of collapse and Isagi Yoichi is on the verge of a full blown egoist awakening. Chapter 321, “Relentless,” is set to continue this onslaught, with Isagi and Rin pushing their rivalry to its absolute limit.


Blue Lock Chapter 320 Recap: The Third Goal and the Beast’s Awakening

Blue Lock Chapter 320, “HERO or DIE!!” was an incredible chapter that showcased Rin Itoshi’s new power. The chapter began with a flashback to Rin’s anger management training, where he resolved to destroy Isagi and his brother, Sae Itoshi. This new conviction allowed him to tap into his “Beast of Destruction” form.

Isagi and Rin then launched their “variable zero top system” overwhelming Nigeria’s defense. However, in a moment of pure egotistical brilliance, Rin used Isagi as a crutch, flipping over his rival to score the third goal of the match. The goal, a testament to Rin’s “Beast” form, put Japan up 3-0 and left Isagi completely flabbergasted. The chapter ended with Isagi’s shocked expression and Rin’s taunt, as the full extent of his new, relentless ego was unleashed.


Blue Lock Chapter 321 Predictions & Theories: The Race for the Goal

With the score now 3-0, the game is no longer about winning, it’s about ego. Chapter 321, “Relentless” will be a direct continuation of this new, intense rivalry between Isagi and Rin.

  • Isagi’s Revenge: Isagi was just outsmarted by Rin in a way that was both strategic and disrespectful. This will undoubtedly be a major blow to his ego. The chapter will likely show a more determined and relentless Isagi, now focused not only on winning the game but on defeating Rin. He will try to outwit his rival and score his first goal of the tournament.
  • The New Predator: Rin, having awakened his new “Beast of Destruction” form, will be a formidable presence on the field. The chapter will showcase his new, relentless playing style, where he will be a constant threat, hunting down every opportunity to score and destroy his opponents.
  • Nigeria’s Final Breath: With the score 3-0 and the “Beast of Destruction” on the loose, Nigeria is on the brink of a complete collapse. We may see them in a state of utter despair, with some players giving up completely. Onazi and his team may try to make one last, desperate attempt to score a goal, but their efforts will likely be futile against the combined might of Isagi and Rin.
  • Sae’s Reaction: Rin’s new form is directly tied to his desire to destroy his brother, Sae. The chapter may cut to Sae watching the game, possibly in Spain and show his reaction to Rin’s new power. This would set up a future confrontation between the two brothers, a clash of egos that will define their relationship.

Who will come out on top in this intense ego clash? And will Nigeria be able to score a goal before the match is over? Let us know your theories in comments!
