There’s a special case in anime: the shift in mindset and acceptance that’s happened across the industry over time. Because of that evolution, stories with harsher settings, different perspectives, and bolder ideas are not only allowed today — they’re celebrated. Realistically, a lot of modern anime (and manga) would’ve been rejected in earlier eras for being too dark or unsettling. But today, the landscape is different.
Now, series with a strong plot and a solid creative vision can succeed even if they include intense psychological themes, brutal violence, and a more hopeless tone. That’s where what many fans call “dark anime” comes from — stories where:
Beloved, important characters have a real chance of dying.
Themes like trauma, despair, and death are central.
The protagonists don’t easily become “pure” heroes.
The world is cruel, and the ending doesn’t have to be happy — it can be neutral, harsh, or even brutal.
In a way, these stories can feel more “realistic” than traditional shōnen. And that’s exactly why they’ve become so popular: they don’t just entertain — they take risks, they surprise you, and they tell stories with a different level of weight.
That’s also where a label fans love using comes in: the “Big Three” of dark anime/manga, which (as mentioned in another post on this blog) would be Jujutsu Kaisen, Hell’s Paradise, and Chainsaw Man.
Out of the three, Jujutsu Kaisen is the one that hit hardest and impressed audiences the most — and honestly, it has so many elements worth highlighting. It’s animated by MAPPA, a studio known for consistently high production quality (and yes, it also adapts the other two “dark giants”), and the manga was written by Gege Akutami.
So let’s go over everything that’s aired so far from this intense, dark series.
📖 Synopsis
The story follows Yuji Itadori, a high school student with unusually strong physical abilities. His life flips upside down when he comes into contact with a cursed object: one of the fingers of Ryomen Sukuna, a terrifying evil spirit known as the “King of Curses.”
To protect his friends, Yuji swallows the finger — and becomes Sukuna’s vessel. Instead of being executed immediately, he’s recruited by the sorcerer Satoru Gojo and enrolled in the Tokyo Jujutsu High School, where he trains to exorcise curses alongside Megumi Fushiguro and Nobara Kugisaki.
🌑 World and setting
The world of JJK revolves around sorcerers who exorcise curses. Curses are ranked by class, with Special Grade being the strongest.
Curses are born from human cursed energy, which comes from negative emotions like fear, hatred, anger, jealousy, and anxiety. When that energy builds up in a place — or around a specific idea (fear of hospitals, death, the ocean, etc.) — it can take physical form and become a curse.
In short: curses are the embodiment of human negativity. And the stronger and more widespread that negativity is, the more powerful a curse can become.
Because they’re born from negative emotions, curses are naturally dangerous. They cause death, disasters, and suffering. If they aren’t dealt with quickly, they grow stronger — and many of them actively enjoy attacking and tormenting humans.
🔮 Cursed energy and Reverse Cursed Technique
Both sorcerers and curses possess cursed energy. Every power system in JJK is built around it.
From cursed energy, there’s also Reverse Cursed Technique (positive energy), created by multiplying cursed energy against itself. This reverse energy is especially useful for healing, and it can also be effective for destroying curses more easily.
🔗 Binding Vows: the core of the system
What makes this world even more compelling is how complex cursed energy really is — because from that complexity come Binding Vows, one of the smartest concepts in the series.
Binding Vows are contracts you can make with yourself or with other sorcerers. You set a condition in exchange for increased power.
A clear example: Nanami, who boosts his strength when fighting outside of his “working hours.”
Like any contract, you give something to get something. And the higher the risk — or the harsher the punishment for breaking it (even death) — the greater the reward.
The best part is that these vows don’t break the world’s fundamental rules. You can’t just ask to become invincible “for free.” The benefit must match your ability and the cost you’re willing to pay. A sorcerer can’t instantly become the strongest — but they can enhance their technique if they accept an extreme risk.
That’s what hooks you: it forces you to pay attention. When a vow happens, you want to understand how it was possible, what the condition was, and what price is being paid.
🧩 Variety without boredom
All these rules and complexities don’t make the series feel heavy — because Gege adds elements that keep the world diverse and entertaining, such as:
Cursed tools with unique abilities (nullifying techniques, interfering with cursed energy, etc.).
Cursed corpses (artificial bodies created with cursed energy).
Cursed objects as powerful relics that are dangerous and difficult to contain.
And here’s a key detail again: Sukuna’s fingers are cursed objects, and one of them is what triggers the entire story.
The world is also organized through a system: jujutsu schools exist to train new sorcerers and prepare them for their responsibilities.
There are also powerful clans with unique, fascinating techniques. And that brings in a major name: Satoru Gojo, the strongest sorcerer of the modern era, connected to an important lineage.
In short: the series is extremely well thought out. You have to pay attention to fully understand its world — but everything is built to stay engaging instead of overwhelming.
🎬 Animation and production quality
One of JJK’s biggest strengths is its animation. MAPPA is known for detail and for delivering high-quality battle shōnen.
The series improves dramatically with each season, and its creativity keeps growing as the story progresses. Even the openings reflect this: visually, they hint at what’s coming — but you often don’t fully understand it until it happens. That’s a smart creative choice.
The fights also level up over time, especially in the Shibuya Incident arc, where the direction and choreography are incredibly sharp.
A clear example: Megumi vs. Toji.
And the fight that hit the hardest, of course: Sukuna vs. Mahoraga. The scale, destruction, and detail were so intense that there’s even an extended version in the Blu-ray release.
👁️ Visibility: brutality and the evolution of anime
That battle (and many Shibuya scenes) also shows how much the anime industry has evolved: the series depicts chaos and the brutality of death amid massive destruction with striking clarity.
In the past, this level of intensity might not have been as common — or as accepted — in a mainstream shōnen adaptation. Today, it is. And that’s why it lands harder: the brutality the author uses to evoke grief, regret, or shock translates far more strongly in animation.
Anime today reaches different audiences — some series are more kid-friendly, some are clearly aimed at adults, and others bridge multiple age groups. JJK is firmly in the category that pushes intensity higher.
⚡ Power system (and Domain Expansions)
As mentioned earlier, the rules are clear: cursed energy, unique cursed techniques, tools, strategy, and creativity. Because techniques are so varied and exclusive, JJK’s power system can easily be considered one of the best.
Depending on the technique, a character can have the advantage, the disadvantage, or end up in a matchup where nothing is straightforward and improvisation is necessary. If someone is losing, they can rely on tactics, creativity, or even a Binding Vow.
That’s why the system feels “deceptive”: a fight can completely flip if someone applies the rules smartly.
And then there’s the iconic concept: Domain Expansion. The most talented sorcerers can develop one — born from their innate technique and representing its highest expression.
Gege Akutami has said he was inspired by series like Naruto and Bleach. In that sense, Domain Expansion can feel somewhat similar to Bleach’s Bankai, since both represent a character’s most powerful release.
But Domain Expansion isn’t just a “second phase.” It’s the manifestation of a sorcerer’s inner world. When activated, it creates a sealed space where the user gains an absolute advantage — often including a guaranteed hit.
If two Domains are activated:
The more refined Domain overwhelms the other and imposes its space.
If they’re similar, they clash into a battle of endurance, where control, cursed energy, and stability determine the outcome.
👊 A different kind of protagonist
Another key aspect of the series is its protagonist. Yuji has incredible physical ability, but early on he couldn’t manipulate cursed energy like a true sorcerer — not until becoming Sukuna’s vessel.
So far in the anime, Yuji hasn’t had the typical, constant “power-up path,” and because of that he often suffers: he can’t always save people, and he can’t always prevent loss.
Gege takes a protagonist like Yuji and forces him through brutal, traumatic experiences to develop him. The focus isn’t power-ups — it’s the story, the plot, and making sure everything follows logic.
You can feel the author’s philosophy: No character is completely protected if the story demands consequences.
⚠️ Abrupt shift: the Shibuya blow
This is one of the most impressive parts: Season 1 can feel sinister at times, but it also has fresh, light, even happy moments. It feels like a “normal” battle shōnen where you get attached to the cast.
But the entire first season is setup. It’s the foundation.
It exists so you can truly know the characters… and then Season 2 hits with the Shibuya Incident, completely flipping where most people thought the story was going.
That’s where the deepest trauma, the losses, the disasters, and the audience’s real fear show up: that characters you love can actually die.
And that’s the perfect emotional trap — because the characters are what you get most invested in.
👹 Villains that stand out
JJK’s villains feel different for multiple reasons.
There are villains like Jogo who show a certain humanity and even affection for their allies (there’s a scene where he cries). And then there are completely twisted villains like Mahito, who plays his role so well that viewers end up hating him intensely.
Mahito enjoys tormenting Itadori.
And then there’s Sukuna, one of the main villains. He lives inside Yuji because Yuji consumed one of his fingers. Sukuna comes from the golden era of jujutsu (the Heian Era), is the King of Curses, and has a dominant, terrifying personality: he despises the weak and kills without remorse — often playing with his victims first.
It’s also fascinating how Gege presents these villains: they can be monstrous, yet their strategic conversations happen in “calm” or unexpected settings — relaxing on a beach, in a park with kids nearby, or while playing a board game. That contrast is unsettling and incredibly creative.
🎭 Characters
Jujutsu Kaisen has a massive and diverse cast. Among the most acclaimed are:
Yuji Itadori, Megumi Fushiguro, Nobara Kugisaki, Satoru Gojo, Maki Zenin, Panda, Toge Inumaki, Kento Nanami, Shoko Ieiri, Yuta Okkotsu, Aoi Todo, Suguru Geto, Yuki Tsukumo, Choso, Utahime Iori, and Ryomen Sukuna.
And highly relevant secondary characters like: Jogo, Mahito, Hanami, Hakari, Kirara, Mai Zenin, Mechamaru, Noritoshi Kamo, Miwa, Momo, Yaga, Yoshinobu Gakuganji, Mei Mei, Kusakabe, Toji Fushiguro, and many more.
There’s also something Gege does especially well: he gives the strongest characters an insane amount of aura. Sukuna, Gojo, and Toji all have moments that feel like pure dominance.
🌌 Satoru Gojo
Gojo is incredible. He overshadows many characters — even the protagonist. He’s charismatic, funny, and playful… but he also has moments of pure presence because he’s the strongest sorcerer in the modern era.
To fight him, you need extreme strategy: tricks, deception, and preparation. The only one who truly feels comparable is Sukuna.
Even so, it’s obvious he cares about his students and human lives. You see it in actions like saving Yuji and Yuta from execution early in the story (and everything connected to the movie).
Gojo became so beloved that it feels like even Gege didn’t expect that level of impact. And narratively, that creates a challenge: if you have a character that powerful, it becomes harder to create believable threats. The author has to justify why Gojo doesn’t intervene — or find a way to remove him from the equation.
Gojo is the symbol of imbalance in JJK. His existence alone reshaped the balance between sorcerers and curses. Many curses were literally hiding because they feared him.
That’s why he’s so interesting: the villains have to deal with the obstacle of Gojo before they can execute their plans.
🎵 Music, soundtracks, and openings
With each season, JJK improved not only in animation but also in its soundtrack. There are memorable OST moments that elevate fights and intense scenes — like Todo and Itadori vs. Hanami, clashes against Mahito, and Sukuna vs. Mahoraga, which also stood out musically.
The openings became part of the series’ identity. You could argue JJK is one of those anime where almost every opening is strong — and they keep getting better over time.
Some of the most acclaimed include:
“Ao no Sumika” (Hidden Inventory arc) — Tatsuya Kitani
“Specialz” — King Gnu
And more recently, “Aizo”, also by King Gnu, maintaining that signature level of visual and musical artistry the series is known for.
The endings have their own charm too, but in JJK the openings tend to steal the spotlight. Still, one fan-favorite remains the first ending: “Lost in Paradise” — ALI feat. AKLO.
📈 Trendings
JJK is a social media machine. Both the anime and manga spread fast — and it’s one of the most spoiler-heavy fandom spaces out there. Something drops, and you’ll see it everywhere almost instantly.
Edits and memes also went viral: fight edits with “Judas” by Lady Gaga, Hakari edits dancing with “Tuca Donka,” Suicide Squad-style edits, and the iconic meme of Itadori being “007: 0 plot armor, 0 power-ups, 7 traumatic events.”
Beyond being fun, this acted as marketing — the community kept the series trending nonstop.
🧠 Gege Akutami’s boldness
Lastly, one thing that defines JJK is Gege’s boldness.
A lot of people may hate him for specific choices, but the risk he takes deserves recognition. He prioritizes the story and refuses to let it become predictable. His coldness toward characters can be shocking — but it’s also what gives the series credibility: it feels like a world where consequences actually exist.
He can make mistakes like anyone. But as the saying goes: nothing ventured, nothing gained.
And Gege definitely ventures.
🌌 Conclusion
Jujutsu Kaisen isn’t just another battle anime with great animation. It’s proof of how the industry shifted — and started embracing stories that are harsher, riskier, and more conscious of their own rules.
It’s a story where consequences exist.
Where power has limits.
Where the protagonist suffers.
Where villains have identity.
And where no one is truly safe.
Its power system is carefully built. Its world runs on clear rules. Its animation raised the modern shōnen standard. And its narrative isn’t afraid to make uncomfortable decisions. Gege Akutami chose risk over comfort — and that boldness is a major reason the series hit as hard as it did.
From the lighter introduction of Season 1 to the brutal impact of the Shibuya Incident, Jujutsu Kaisen proved it could make you emotionally invested before breaking your expectations.
And maybe that’s the real key to its success.
It doesn’t just entertain. It makes you care… and then reminds you that this world is not forgiving.
That’s why it became a phenomenon. That’s why it set trends. And that’s why when people talk about modern “dark shōnen,” its name is always the first one mentioned.
Jujutsu Kaisen didn’t just follow the genre’s rules. It stretched them. Challenged them. And in many ways, redefined them.
And honestly, it’s no surprise it was named Anime of the Year at the 2024 Anime Awards!
And if Jujutsu Kaisen has proven anything, it’s that its story is far from finished. The next chapter continues expanding its world, raising the stakes, and pushing its characters even further. Here is the official trailer for the latest season as of this post:
🧠 A necessary reflection on audience reception
There’s something worth pausing on — something that recently sparked debate.
During the Culling Games arc, there was an episode that was especially important — not because of action, but because it clearly explained the rules of the game. It was key for understanding how this sorcerer battle royale works, what its conditions and restrictions are, and how events from the past — like the Hidden Inventory arc — helped trigger what’s happening now.
Narratively, it was a crucial episode.
However, because it didn’t include major fights or big explosive moments, it was judged harshly by some viewers. And that raises an important concern.
If studios start prioritizing only immediate, action-driven reception, a dangerous trend could emerge: cutting or downplaying strategic, explanatory, or emotional episodes that are essential for coherence and depth.
A series like Jujutsu Kaisen doesn’t work only because of its fights. It works because it has rules, world-building, consequences, and development.
It’s understandable that part of the audience prefers constant fast-paced action — everyone watches anime with different expectations. But reducing an episode’s value solely because it lacks combat risks missing the most important thing: storytelling.
And this didn’t happen only with JJK. Something similar happened with anime like Solo Leveling, where a more emotional, character-focused episode was undervalued by some viewers even though it was key to understanding the protagonist’s motivations.
Not every episode is meant to visually overwhelm. Some are meant to build.
And without building, impact means nothing.
