He isn't the strongest. Honestly, that’s the first thing you have to accept about Yuji Itadori. In a genre defined by protagonists who eventually become gods, the main character of Jujutsu Kaisen is a weirdly grounding presence. Gege Akutami didn't write a power fantasy; he wrote a tragedy about a kid who just wanted to help people die "properly."
It’s heavy.
Most shonen leads have a dream. Naruto wanted to be Hokage. Luffy wants to be King of the Pirates. Yuji? He just wants to ensure people don't die alone. That specific motivation stems from his grandfather's final words in the very first chapter. It’s a burden, really. This isn't about glory or being the best. It’s about a teenager forced into a world of supernatural cannibalism because he ate a finger on a whim to save his friends.
Talk about a bad first day.
The Curse of Being the Main Character of Jujutsu Kaisen
Being the main character of Jujutsu Kaisen is basically a death sentence. While other series protect their cast with thick layers of plot armor, Akutami seems to take a perverse joy in putting Yuji through the emotional meat grinder.
Think about Junpei Yoshino.
Most stories would have had Yuji save him at the last second, turning him into a lifelong ally. Instead, Yuji watches Junpei transform into a literal monster and die right in front of him. It was the moment fans realized this show wasn't playing around. Yuji’s growth isn't measured in power levels or new flashy transformations—at least not at first. It’s measured in how much trauma he can absorb before he breaks.
He’s a cog. He says it himself during the Shibuya Incident.
"I'm a cog. Cogs don't have to think about their purpose. They just have to play their part."
That’s a bleak way to look at yourself. But in the world of Curses and Sorcery, it’s the only way he survives. He stops seeing himself as a hero and starts seeing himself as a tool to exorcise Sukuna, the King of Curses living inside him.
What Sets Yuji Itadori Apart from the Rest?
If you look at the landscape of modern anime, Yuji is an outlier. He doesn't have an innate Cursed Technique for the vast majority of the series. While Megumi Fushiguro is summoning shadow dogs and Nobara Kugisaki is using voodoo dolls, Yuji is just... hitting things. Hard.
Very hard.
His primary "move" is Divergent Fist, which is actually a flaw in his timing. His superhuman physical strength is so great that his Cursed Energy can't keep up, creating a double-impact effect. Later, he masters Black Flash—a phenomenon that happens when Cursed Energy is applied within 0.000001 seconds of a physical hit. But even then, Black Flash isn't unique to him; he’s just weirdly good at it.
The main character of Jujutsu Kaisen relies on grit. There’s no "Talk-no-Jutsu" here. Yuji doesn't convince his enemies to be good people. He fights until he can't move, and then he fights some more. This lack of a "special" bloodline ability (initially) makes his struggles feel far more visceral.
He earns every inch of ground.
The Shibuya Incident Changed Everything
Everything before Shibuya feels like a prologue once you see the destruction Sukuna wreaks using Yuji's body. This is where the main character of Jujutsu Kaisen loses his innocence completely. Seeing the crater where a city block used to be—knowing your own hands did it, even if you weren't "in control"—is enough to shatter anyone.
The battle against Mahito is the peak of this arc.
Mahito is the perfect foil for Yuji. He represents the absolute cruelty of humanity, while Yuji represents its capacity for self-sacrifice. When Yuji finally chases Mahito down through the snow, looking like a literal wolf hunting its prey, the dynamic shifts. Yuji accepts that he is a murderer. He accepts that he is a curse-killer.
He stops trying to be a "good person" and decides to be a "necessary" person.
Debunking the Sukuna Vessel Misconception
People often think Yuji is just a host for Sukuna. Like he's just the wrapper for the real threat. But as the manga progressed—specifically into the Culling Game and the Shinjuku Showdown—we learned that Yuji’s lineage is way more complicated than "random athletic kid."
Kenjaku, the ancient sorcerer, is his "mother."
Yeah. It’s gross.
This revelation changes the context of Yuji’s existence. He wasn't a lucky (or unlucky) bystander who happened to be a one-in-a-million vessel. He was engineered. He was designed from birth to hold Sukuna. This adds a layer of existential dread to the main character of Jujutsu Kaisen. Is he even a person, or is he just a biological cage?
His resilience in the face of this truth is what makes him compelling. He finds out his entire life was a setup by a brain-hopping psychopath, and his response is to keep swinging his fists.
Why Yuji Doesn't Need a Domain Expansion (Until He Does)
For years, fans begged for Yuji to get a Domain Expansion. In Jujutsu Kaisen, a Domain is the pinnacle of sorcery. It’s your inner world manifested. For a long time, Yuji didn't have one because he didn't have a technique.
He was just "The Black Flash Guy."
But the beauty of his character development is how he slowly absorbs Sukuna's techniques—Shrine and Cleave—while also developing his own soul-swapping and Blood Manipulation (inherited from the Death Paintings). When he finally steps up to face Sukuna in the final arcs, he isn't just a brawler anymore. He’s a hybrid of everything he has suffered through.
His "Technique" is effectively the result of his misery.
The Reality of Yuji's Relationships
Nanami Kento was the father figure he needed. Satoru Gojo was the mentor he deserved. Nobara and Megumi were the family he chose.
And he lost almost all of them.
The isolation of the main character of Jujutsu Kaisen is a recurring theme. The higher the stakes, the fewer people are left standing next to him. This is a stark contrast to the "Power of Friendship" trope. In this series, friendship is a liability. It’s something Sukuna can use to hurt you.
Watching Yuji navigate this loneliness without becoming a villain himself is why he’s so beloved. He stays kind. Despite the scars, both literal and metaphorical, he still cares about the "proper death."
Actionable Insights for Fans and Writers
If you're looking to understand why Yuji works as a character, or if you're a writer trying to capture that same energy, keep these points in mind:
- Flaws as Strengths: Yuji's Divergent Fist was a mistake that became a weapon. Don't make your protagonist perfect from the jump; make their errors useful.
- The Weight of Choice: Yuji chose to eat the finger. He chose to enter the world. Every trauma that follows is a direct consequence of his initial agency.
- Deconstruct the Archetype: Take a standard trope (the "chosen one") and strip away the perks. If your character is "chosen," make it feel like a burden, not a gift.
- Physicality Matters: In an era of magic systems, never underestimate the impact of a character who simply refuses to stay down.
- Avoid the Power Creep: Yuji remains relevant by being clever and durable, not just by getting bigger lasers.
The story of Yuji Itadori is a masterclass in how to write a protagonist who suffers without it feeling like "misery porn." There's a purpose to the pain. He represents the human spirit's refusal to be extinguished by a world that is fundamentally unfair. Whether he lives or dies by the end of the story, he has already proven that being a "cog" in the machine of justice is more heroic than being the machine itself.
To truly appreciate his journey, re-watch the early episodes and look at the light in his eyes. Then look at him during the Shinjuku Showdown. The transformation isn't just in his powers—it's in his soul. That is the hallmark of a truly great main character.
Next Steps for Deepening Your JJK Knowledge:
- Compare Yuji’s philosophy of a "Proper Death" with the actual Buddhist concepts of Samsara and Karma—it adds layers to why he's so obsessed with the end of life.
- Analyze the "Crossover" moments where Yuji uses Soul Perception; this is actually his most unique trait, allowing him to damage the essence of a person rather than just their physical body.
- Re-read the "Perfect Preparation" arc to see how Yuji’s lack of ego allows him to work with people like Maki and Choso without the usual shonen rivalry drama.
