◆ Introduction

Hi there! I’m 『Yukidaruma』, the admin of this site! My goal is to build the “World’s Best Blue Lock Site,” and I’m pouring my absolute “Ego” into every single article I write!!

I mainly cover the latest chapters, volumes, deep-dive theories, character profiles, and detailed reviews—and I’ve already crossed the 300-article milestone!!

Thanks to Blue Lock, a true “Ego” has awakened inside my heart!! I’ll do my absolute best to share the greatness of this masterpiece with all of you! ❄️⚽

① The Chapter Where Seishiro Nagi Was Eliminated

The specific chapter where Seishiro Nagi’s elimination was confirmed is Chapter 298.

② About Seishiro Nagi’s Elimination

At the very end of Chapter 298, Seishiro Nagi’s final annual salary ranking was announced as 24th place, meaning his exclusion from the U-20 Japan National Team roster was officially set in stone.

During the third match of the Neo Egoist League (NEL)—Germany vs. England—Nagi scored a shocking, spectacular goal despite his team’s defeat. Thanks to this incredible feat, he received a massive initial offer of 88 million yen.

However, he struggled to make a significant impact in the subsequent matches. After the following match, his valuation plummeted to 43 million yen (-45 million yen)—a massive downgrade… Following the match after that, it dropped even further to 40 million yen (-3 million yen).

His evaluation continued to slide down, and in the end, his bid bottomed out at 24 million yen, confirming his elimination. This survival test allowed only the top 23 players to advance to the next stage (the Third Phase) as members of the U-20 Japan National Team, and Nagi unfortunately missed the cut by the narrowest of margins…

This was such a mind-blowing development… The author, Muneyuki Kaneshiro-sensei, always thinks outside the box, but this twist was completely unexpected! But hey, that’s Blue Lock for you!! That’s exactly why it’s so damn interesting! (^^♪

③ The Scene Where Seishiro Nagi Leaves Blue Lock

From Chapter 300, this is the heartbreaking scene where Seishiro Nagi’s elimination is finalized, and he walks away from Blue Lock. Reo Mikage breaks down in tears, and even Yoichi Isagi has tears in his eyes…

Isagi has been absolutely ruthless during matches lately, but the moment the final whistle blows, he goes right back to being his usual caring self who genuinely values his friends. He’s such a truly good guy (T_T)

④ 8 Foreshadowing Clues Predicting Seishiro Nagi’s Elimination

Believe it or not, there have actually been several scenes from a while back that strongly hinted at Seishiro Nagi’s eventual departure (foreshadowing)!

From here, I’ll introduce those specific moments along with the volume and chapter numbers they appeared in!

(1) Vol. 22, Chapter 191: “Nagi Filled with a Total Sense of Satisfaction”

This takes place during the Bastard Munchen vs. Manshine City match.

The scene occurs right after Seishiro Nagi bypasses Yoichi Isagi and scores that spectacular “Five-Stage Revolver Fake Volley.” Having achieved his ultimate goal of “beating Yoichi Isagi,” Nagi is filled with a profound sense of total satisfaction.

Look at that completely satisfied look on his face… It really feels like his “dream” came true, but because of that, he already looks totally burned out here (◎_◎;)

(2) Vol. 22, Chapter 191: “Abandoned by Agi”

Seeing Nagi and Reo Mikage team up again, Agi judges that Nagi has “abandoned his own independent thinking process” and completely washes his hands of him.

Up until the middle of this match, Nagi and Reo weren’t cooperating and were fighting as individuals. However, the turning point was when Nagi asked Reo for help. Once they started playing together again, Nagi stopped thinking for himself and “left everything up to Reo”—and that was the fatal mistake… Agi has absolutely zero interest in a player who stops thinking for themselves (_;

(3) Vol. 22, Chapter 191: “Nagi running out of his next goal”

Having achieved his ultimate goal of “beating Yoichi Isagi,” Seishiro Nagi tries to brainstorm a new “goal” to fire himself up again, but absolutely nothing comes to mind…

After all, you can’t survive in Blue Lock without a burning “ego”… At this point, rekindling the fire in a completely satisfied Nagi is going to be a massive uphill battle…

(4) Vol. 23, Chapter 196: “Jinpachi Ego’s Harsh Evaluation”

Jinpachi Ego completely dismisses Seishiro Nagi’s “Five-Stage Revolver Fake Volley,” flatly stating that it has “absolutely zero reproducibility.” He then leaves Nagi with a chilling warning: “A success that exceeds your true talent carries the risk of self-destruction.”

Ego-san absolutely detests these kinds of “unexplainable, fluke plays” (;^ω^)
I always feel like he’s exceptionally harsh and strict when it comes to Nagi…

(5) Vol. 23, Chapter 201: “Goodbye, Genius”

Nagi was so satisfied with beating Isagi that his body literally stopped pushing for further growth. On the flip side, Yoichi Isagi’s mind is running at full throttle, constantly analyzing his next evolution!

Nagi might have outsmarted him just moments ago, but Isagi immediately overtook him right after! Facing a Nagi who had stopped moving forward, Isagi no longer felt any sense of rivalry toward him. “Goodbye, genius.”

Was this “Goodbye, genius” directed at the Nagi of that specific match? Or was it a haunting prophecy for the future Nagi?

(6) Vol. 28, Chapter 240: “The lukewarm ones are the first to drop straight into hell”

This scene takes place during the Manshine City vs. PXG match, right when Rin Itoshi scores a spectacular hat-trick to seal the victory. Rin Itoshi delivers a freezing warning to Seishiro Nagi, who had been playing with a half-hearted attitude: “The lukewarm ones are the first to drop straight into hell.”

He hit the nail right on the head (◎_◎;)
You can’t survive Blue Lock with that kind of soft, naive mindset, Nagi…

(7) Vol. 28, Chapter 245: “Have the courage to let go of what is precious to you”

This takes place after the Manshine City vs. Ubers match.

Convinced that “no further growth can be expected” under their current dynamic, Agi gives Reo Mikage a piece of advice: “Have the courage to let go of what is precious to you (Nagi).”

I guess you really can’t get any stronger by relying on “cooperation” in this environment… The choice made by Reo and Nagi to ignore this warning is exactly what ultimately led to Nagi’s elimination…

(8) Vol. 28, Chapter 245: “Go die once”

This also takes place after the Manshine City vs. Ubers match.

Seishiro Nagi had completely lost the unique “troublesome aura” that used to make him so dangerous. Barou Shoei saw right through Nagi’s lack of motivation and called him out.

“Go die once” practically sounds equivalent to “Go get yourself eliminated once,” doesn’t it? ( ;∀;) It honestly feels like Barou was explicitly predicting Nagi’s drop-out right here.

⑤ 3 Mysteries Surrounding His Elimination

While Seishiro Nagi’s elimination has been finalized, there are actually quite a few “mysteries” and unanswered questions surrounding how it went down!

From here, I will dive deep into those specific mysteries!

To be perfectly honest, a lot of it leaves me thinking, “Come on, that’s just pushing it too far,” you know? (◎_◎;) It almost feels like the author was just desperately looking for a way to make Nagi fall…?

(1) The Drastic Plunge in Annual Salary

As you can see from the changes in Seishiro Nagi’s valuation, he is the only player who suffered such an extreme, catastrophic market crash.

Among the players whose salaries increased, Rin Itoshi saw the biggest jump with a whopping 140 million yen increase. Since Rin scored a hat-trick to secure the victory in that match, his market value naturally skyrocketed! Many other players also successfully raised their value—such as Yoichi Isagi increasing his by 100 million yen—but Nagi is the only one whose value plummeted so drastically.

To be perfectly honest, while it’s true that Nagi hadn’t been performing well and his gameplay was highly inconsistent, it’s still hard to believe that his value would drop this much. A total crash of -64 million yen is truly extraordinary… If he had been ejected from a match or completely sabotaged a game, such a drop might make sense, but a radical shift like this is just incomprehensible.

Sure, Nagi was in a slump, but the drop was way too excessive! I actually calculated the salary trends for all the other players, and a plunge of this magnitude is honestly unnatural (◎_◎;)

(2) Jin Kiyora’s Inexplicable Treatment

In the final salary rankings, Jin Kiyora locked in the 22nd spot. Up until the final match, Kiyora hadn’t played a single minute on the pitch. He made his very first appearance in the 10th match—Germany vs. France—and instantly received a bid of 2600 million yen.

However, looking back at his performance in that game, his only real notable contribution was his “assist to Kaiser.”

A 26-million-yen valuation for just one assist!? Doesn’t that seem a bit skewed? Based on past salary increases, the standard breakdown roughly calculates to:

1 Goal: 25 to 30 million yen
1 Assist: 10 to 15 million yen
Match Appearance: 3 to 5 million yen

So, if you look closely at Kiyora’s contribution in that match, even with the most generous evaluation, his bid should have topped out at around 20 million yen at best. It wasn’t even a match-winning assist, and he didn’t make any other major plays, so why did his value spike so high!?

Furthermore, Kiyora’s official moniker is “The Borderliner.” This signifies that he is a player who has survived this brutal Blue Lock project by constantly walking the fine line of life and death. If the author truly wanted to emphasize his identity as “The Borderliner,” the most narratively satisfying choice would have been to put him in 23rd place—letting him survive by the absolute skin of his teeth!

Therefore, putting Kiyora in 22nd place makes no sense for two main reasons:

The bid amount doesn’t match his actual performance.
It completely undercuts his identity as “The Borderliner.” Because of this, I personally disagree with this placement.

Just to be clear, I am not hating on Jin Kiyora! I genuinely love his playstyle and root for him! I’m simply pointing out that his treatment in this specific ranking feels highly inconsistent (;^ω^)

(3) Nijiro Nanase’s Dramatic Presentation

The 23rd and final spot on the U-20 Japan National Team roster went to Nijiro Nanase. Nanase also showed great performance in the final match between Germany and France, so it was inevitable that his ranking would rise.

His key contributions in that match included:

Revealing his ambidexterity (being two-footed)
Executing solid post-play for Rin Itoshi

While he didn’t make any earth-shattering plays, his appeal to the bids was definitely a success. Nanase’s salary trend steadily climbed from 3 million yen → 16 million yen → 25 million yen. Even without flashier, visible stats like goals or assists, he consistently raised his value just by making a solid impact on the pitch.

But with all that said… Is Nijiro Nanase actually a superior player to Seishiro Nagi? To be frank: “Absolutely not!”

If the system inherently rewards a player’s value just for stepping onto the field, then Nagi—who has started in every single match—should practically never see his salary drop!

So, why did Nanase survive over Nagi? It was purely for the sake of dramatic presentation. The reveal of the final salary rankings in Chapter 299 was masterfully executed, and the build-up to the final 23rd member was incredibly stylish. The screen initially only displayed “23 NA…” and everyone reading assumed it was going to be “23 NAGI.” But in a shocking twist, it turned out to be “NANASE”… I highly suspect that Nanase was placed in the 23rd spot primarily to pull off this brilliant, mind-boggling narrative swerve.

Nanase is a fantastic player with ambidexterity—a weapon that could potentially make him the next Noel Noa—but based strictly on his actual track record so far, him surviving over Nagi still feels like a massive stretch…

⑥ The Possibility of Seishiro Nagi’s “Revival”

Is it really possible for Seishiro Nagi—an incredibly popular character who even stars as the protagonist of the spin-off series “Blue Lock -EPISODE Nagi-“—to just stay eliminated and leave the story like this?

From here, let’s dive into the highly anticipated topic of Seishiro Nagi’s “revival”!

To give you my conclusion right upfront, Seishiro Nagi… “will almost 100% make a comeback!!”

While there are various narrative reasons backing up this revival theory, the scene in Chapter 300 where Seishiro Nagi leaves Blue Lock is particularly suspicious!

Other major reasons include:

The ongoing serialization of his dedicated spin-off, “Blue Lock -EPISODE Nagi-“
His status as a massively popular, top-tier character in the franchise

Considering he is such a central figure who is deeply intertwined with the core plot of the series, a glorious comeback seems absolutely guaranteed!

Looking closely at this scene, you can see that the “fire” (the heat of his ego) hasn’t completely died out in Nagi’s eyes yet! This is undoubtedly massive foreshadowing for his ultimate resurrection!!

⑦ 4 Potential Revival Routes for Seishiro Nagi

From here, let’s explore 4 possible paths through which Seishiro Nagi could make his ultimate comeback!

(1) The “Wild Card” Route

Just like how Rensuke Kunigami previously made his return through the “Wild Card” (loser’s resurrection) system after being eliminated, it wouldn’t feel out of place if a similar measure was implemented this time around.

However, the major difference between Nagi’s current situation and Kunigami’s back then lies in “the weight of the elimination.” What this means is that when Kunigami was dropped, the Blue Lock Project had only just begun, and elimination strictly meant “permanently losing the right to play for the Japan National Team.”

In contrast, the concept of elimination in this Second Phase—the Neo Egoist League (NEL)—is vastly different. Even if a player is eliminated from the project, as long as they have received a bid from a pro club, they can still sign with that offering club. Furthermore, it’s currently unclear whether the original penalty of “permanently losing eligibility for the national team” still applies…

Note: Although Seishiro Nagi failed to make the U-20 Japan National Team roster, he did receive an official bid, meaning he can still enter the professional world through that club despite his elimination.

Because the circumstances are inherently different from Kunigami’s Wild Card situation, the probability of this specific route might be a bit low…

Since the Blue Lock Project has already reached the point of “determining the final survivors,” the traditional concept of a “Wild Card revival” might no longer exist here (◎_◎;)

(2) Extension of the Roster Size

In the fictional world of Blue Lock, it was initially established that the U-20 Japan National Team roster would consist of 23 players.

However, in our real world, the official World Cup roster limit was actually increased to 26 players starting from the 2022 Qatar World Cup! While it used to be 23 players since the tournament’s inception, it was expanded to 26 due to specific logistical reasons.

Given this real-world parallel, there is a very high probability that the roster size in the world of Blue Lock will also be adjusted from 23 → 26 players! If that happens, the players ranked 24th to 26th might get a last-minute addition to the team, making a Seishiro Nagi revival highly plausible.

I personally believe this is a very strong and likely theory!

Additional Info!!

In Chapter 308, a truly shocking statement was made by Hirotoshi Buratsuta!? As it turns out, my prediction was spot on—the official roster size for the U-20 World Cup is 26 players, not 23!! On top of that, the existence of a mysterious system called the “Buratsuta 3”—where Buratsuta himself gets to arbitrarily select the remaining 3 players—has officially been unveiled!?

(3) Injury Substitutions & Training a New Goalkeeper

Although the 23-man U-20 Japan National Team roster is currently finalized, if any registered player suffers an injury, an additional call-up to the squad is legally permitted.

For instance, if one of the forwards sustains a long-term injury during a match, their registration can be canceled, allowing a replacement player to be brought into the team!

While this is purely my personal speculation, the players who might face a potential risk of dropping out due to these physical or narrative reasons are:

Hyoma Chigiri → Aggravation of his pre-existing knee injury.
Kenyu Yukimiya → Worsening of his pre-existing eye condition.
Players whose future narrative impact might be questionable → Shuto Sendo, Nijiro Nanase, Jin Kiyora, Zantetsu Tsurugi, Jingo Raichi, and Gen Fukaku.

Since Gin Gagamaru is effectively the only reliable goalkeeper, Gen Fukaku managed to survive as the “backup GK.” However, looking ahead to future matches, there is a distinct possibility that a brand-new goalkeeper will be trained from among the existing outfield players!

Personally, I think it would be incredibly fascinating if someone like Jin Kiyora underwent a position change to goalkeeper, just to prove the narrative point that “you can still be an elite GK even if you are on the shorter side”!

Shuto Sendo might be the most likely candidate to be swapped out? (◎_◎;) The fact that he somehow made the final roster despite not standing out much recently feels highly suspicious…

(4) Appearing as a Rival Country’s Player

While I personally think the likelihood of this route is extremely low, there are quite a few theories floating around the internet suggesting, “What if he changes his nationality and appears as an enemy player?”

Since many fans predict that “he will eventually form a deadly duo with Agi from Manshine City,” switching his eligibility to England would probably be the most logical choice if this theory holds water.

It’s true that Seishiro Nagi’s family background and upbringing remain a total mystery. Despite being such a prominent character with massive screen time, his past hasn’t been deeply explored yet, which might mean there’s a hidden reason behind it all (◎_◎;)

⑧ Thoughts & Summary

To summarize this discussion on Seishiro Nagi’s elimination and his ultimate revival:

Aren’t there other players who realistically hold less market value than Seishiro Nagi?
The probability of his comeback is incredibly high!

To be completely blunt, Seishiro Nagi’s elimination just doesn’t make logical sense… I refuse to believe that Nagi is fundamentally inferior to the likes of Jin Kiyora, Nijiro Nanase, or Shuto Sendo. When it comes to raw latent potential and explosive match-deciding power, Nagi overwhelmingly outclasses them by a mile.

Most likely, this “Nagi’s elimination” twist is merely a narrative plot device designed to hype up the story to its absolute peak. Therefore, Nagi is bound to make his glorious return at some point down the line!

In fact, much like how Rensuke Kunigami underwent a massive dark evolution, we might get to witness a completely reborn, newly evolved Seishiro Nagi. Because of that, I’m actually incredibly excited for what’s to come!

There is no way the author is going to permanently drop such a massively popular, money-making character in such a lackluster way! If you are a die-hard Nagi fan, you can absolutely rest easy and look forward to his return! (‘ω’)ノ
