Blue Lock: Major predictions for Chapter 303 spoilers

Blue Lock chapter 303 will be published on Wednesday, May 28, 2025, at 12 am JST. With only 50 days left until the start of the U-20 World Cup in the manga, fans wish to know what could happen next with the Blue Lock Japan players. However, with the manga series on a break, we have brought a list of predictions for chapter 303 spoilers.

The manga's previous chapter saw Seishiro Nagi return to normalcy and to Hakuho High School. While he had become popular, Nagi did not want to continue playing football. However, this was a lie, as Nagi seemed to miss Blue Lock a lot. Unfortunately, with no way to return to the training program, he had an emotional breakdown.

What to expect from Blue Lock chapter 303?

While Ego Jinpachi has picked the best 23 players from the Neo Egoist League for Japan's U-20 squad, he may have more work to do. As fans may remember, during the Neo Egoist League, most players had acquired new weapons and adapted to new playstyles, possibly harming any chemistry they had with each other.

Therefore, the manga could see Ego Jinpachi reveal his training plans for the team. This training regime will likely be similar to the Third Selection Arc, using which Ego Jinpachi picked the starting lineup for the match against the U-20 Japan squad. Fortunately, this time, he has players like Oliver Aiku and Ryusei Shidou to pick for his starting lineup.

While Sae Itoshi never participated in the Neo Egoist League, he, too, is a Japanese player who met the criteria to play in the U-20 World Cup. Therefore, it might be a huge loss for the Japanese national team not to pick him for the U-20 squad.

However, considering that the story has pitted Rin Itoshi against his older brother, it hardly seems possible that Kaneshiro may add Sae Itoshi to the team. Therefore, the manga's next chapter could see Ego Jinpachi revealing why he wasn't going to call Sae Itoshi for international duty. Meanwhile, there is also the chance that Japan's senior squad might issue a call-up for Sae to join their ranks.

While it is highly unlikely, there is a chance that the manga might skip over any short training arcs and directly skip to the U-20 World Cup. With that, fans can expect to see the Blue Lock Japan players head out to the competition, which might be hosted in a foreign country.

Therefore, viewers might see Yoichi Isagi and others travel abroad for the upcoming international competition.
