Who is Yuji Itadori? He’s the main protagonist of Gege Akutami’s Jujutsu Kaisen — an ordinary high schooler with extraordinary physical strength who becomes the living vessel for Ryomen Sukuna, the King of Curses, after swallowing one of Sukuna’s cursed fingers. That single choice pulls Yuji into the world of jujutsu sorcery, where he trains at Tokyo Jujutsu High and grows from a fighter with no cursed technique of his own into one of the story’s most formidable sorcerers.

Yuji Itadori’s Backstory
Before any of this, Yuji lived a quiet life in Sendai City, raised by his grandfather after his parents’ early deaths. He wasn’t a sorcerer and had no cursed energy training. What he did have was freakish physical ability — the kind of raw strength and speed normally reserved for trained fighters, developed simply from years of physical conditioning rather than any supernatural source.
Everything changes when Yuji joins his school’s Occult Research Club and encounters a cursed object: one of Ryomen Sukuna’s twenty fingers. When curse spirits attack to claim the finger, Yuji makes a split-second decision to swallow it rather than let it fall into worse hands. Instead of dying instantly, as anyone would expect, Yuji survives — because Sukuna’s spirit recognizes something in him and chooses to let him live, at least for now. That decision saves Yuji’s life and permanently changes it, since his body is now Sukuna’s vessel.
Yuji Itadori and Sukuna: How the Vessel Relationship Works
Swallowing Sukuna’s finger doesn’t just give Yuji power — it means Sukuna’s consciousness now shares his body. Under specific conditions, Sukuna can seize control, and the two exist in an uneasy, often hostile arrangement: Sukuna treats Yuji with contempt and views their shared body as a temporary inconvenience, while Yuji has to live with an ancient, remorseless killer as an unwilling passenger.
Sorcerers across the story respond to this arrangement in sharply different ways. Some want Yuji executed immediately, reasoning that killing him is the safest way to prevent Sukuna’s full return. Others, including his teachers and closest classmates, fight to protect him instead — arguing that Yuji deserves to be judged for his own choices, not for the curse trapped inside him. That tension, between what Yuji carries and who Yuji actually is, runs through the entire series.
Yuji Itadori’s Powers, Explained
Yuji’s power set grows substantially over the course of the story, moving from pure physical ability to genuine cursed technique mastery.
Superhuman physical ability. Before he ever touches cursed energy, Yuji already has strength, speed, and durability far beyond a normal teenager, purely from natural talent and physical training.
Divergent Fist. Yuji’s first real cursed technique. It works by striking an opponent with a cursed energy blow that lands in two waves — an initial hit followed by a second, delayed impact — making it deceptively hard for opponents to brace against.
Black Flash. Widely regarded as one of the most difficult techniques to intentionally trigger in the entire series. It requires hitting a cursed energy blow within an extremely precise timing window, multiplying the attack’s power dramatically when it connects. Most sorcerers land one by pure chance in an entire lifetime; Yuji becomes remarkably skilled at landing them consistently, eventually stringing together consecutive Black Flashes in a way very few characters in the series ever match.
Blood Manipulation. Gained later in the story after a specific story event involving cursed womb-related enemies, giving Yuji a technique that lets him control and weaponize blood — his own or an opponent’s — in combat.
Shrine. A technique tied directly to his role as Sukuna’s vessel, awakened under extreme combat pressure. It reflects just how deeply Sukuna’s own cursed technique has become engraved into Yuji’s body over time.
Yuji Itadori’s Personality
Yuji’s defining trait is a fierce, uncomplicated sense of justice: he consistently chooses to protect people, even strangers, even at direct cost to himself. Early in the story, he frames his own goal in deliberately simple terms — wanting people to live and die properly, surrounded by others, rather than alone. That simple philosophy sits in constant tension with the brutal reality of his situation as Sukuna’s vessel, since the story repeatedly forces him to weigh his own safety, and sometimes his own life, against the safety of people around him.
Despite the darkness surrounding his circumstances, Yuji is written with a lightness that stands out in the cast — quick to joke, quick to connect with new people, and rarely self-pitying even when the story gives him every reason to be.
Yuji Itadori’s Key Relationships
- Megumi Fushiguro — the classmate whose encounter with a curse indirectly leads Yuji to swallow Sukuna’s finger in the first place; their friendship becomes one of the story’s central relationships.
- Nobara Kugisaki — Yuji’s other first-year classmate at Tokyo Jujutsu High, forming a tight three-person team alongside Megumi.
- Satoru Gojo — Yuji’s teacher, whose decision to protect rather than eliminate Yuji shapes much of the story’s early direction.
- Ryomen Sukuna — not a relationship in any conventional sense, but the defining, inescapable presence in Yuji’s life from the moment of his transformation onward.
Why Yuji Itadori Resonates With Readers
Part of what makes Yuji stand out from a typical shonen lead is that his core power isn’t a special bloodline or a chosen-one destiny — it’s a split-second act of selflessness that permanently complicates his life. Rather than being rewarded cleanly for that choice, Yuji spends the story living with its consequences, which gives his growth a grounded, earned quality that fans consistently point to as central to his appeal. If you’re comparing protagonists across shonen series, our explainers on Zoro’s bounty and powers and Eren Yeager’s Titan transformations cover two other heavily discussed cases.
