Quick Answer: Yuji Itadori is not immortal in the traditional sense, but he possesses extraordinary durability and healing abilities due to his unique circumstances in the Jujutsu Kaisen universe. He became the vessel for Ryomen Sukuna, the King of Curses, after consuming one of Sukuna's fingers in October 2018. This connection grants Yuji enhanced physical capabilities and rapid regeneration, allowing him to survive injuries that would be fatal to ordinary humans. However, he can still be killed if his body is destroyed beyond his regenerative limits or if Sukuna chooses to take over completely.

Overview

Yuji Itadori is the protagonist of Gege Akutami's manga and anime series Jujutsu Kaisen, which began serialization in Weekly Shonen Jump in March 2018. The story is set in a world where cursed energy from negative human emotions manifests as dangerous supernatural entities called Curses. Jujutsu sorcerers like Yuji combat these threats using cursed techniques. Yuji's journey begins when he joins the Tokyo Metropolitan Curse Technical College after encountering a cursed object - one of the 20 fingers belonging to Ryomen Sukuna, a legendary curse from the Heian period (794-1185 CE). By consuming the finger to save his friends, Yuji becomes Sukuna's vessel, binding the curse's consciousness to his body. This unprecedented event creates a unique host-parasite relationship where Yuji maintains control most of the time, but Sukuna can manifest when certain conditions are met.

How It Works

Yuji's enhanced durability and healing stem from two interconnected mechanisms: his innate physical prowess and Sukuna's cursed energy. First, Yuji possesses exceptional natural athleticism even before becoming a vessel, with abilities comparable to Olympic-level athletes. After consuming Sukuna's finger, his body undergoes transformation at the cellular level. Sukuna's cursed energy permeates Yuji's cells, reinforcing their structure and accelerating regeneration through cursed energy manipulation. When injured, this energy acts as both a protective barrier and repair system, mending tissues at rates far exceeding normal human healing. The process follows jujutsu principles where cursed energy can be converted into positive energy for healing, though Yuji does this subconsciously. Importantly, Yuji and Sukuna share the same body but maintain separate consciousnesses, creating a delicate balance where Sukuna's power enhances Yuji without completely overtaking him unless specific conditions trigger a takeover.

Why It Matters

Yuji's unique condition has profound implications within Jujutsu Kaisen's narrative and themes. His survival as Sukuna's vessel represents an unprecedented breakthrough in jujutsu history, challenging established doctrines about cursed objects and vessels. This directly impacts the series' plot, as various factions seek to control or eliminate him - the jujutsu establishment initially orders his execution, while curse users want to exploit Sukuna's power. Thematically, Yuji's resilience embodies the series' exploration of mortality, sacrifice, and human will against overwhelming power. His ability to withstand Sukuna's influence while utilizing that power for good creates moral complexity about using evil means for righteous ends. This dynamic drives character development and philosophical questions throughout the story, making Yuji's "immortality" a central narrative device rather than just a supernatural ability.
