Satoru Gojo — Jujutsu Kaisen

As second-year students, Gojo and Suguru Geto are assigned to protect Riko Amanai, the Star Plasma Vessel intended to merge with Master Tengen. The assassin Toji Fushiguro ambushes Gojo near the end of the escort mission, then uses a cursed tool that can cancel an active technique to pierce his Infinity. Gojo is left gravely wounded. Geto offers Riko a chance to choose her own future, but Toji kills her before she can leave. Gojo survives by learning reverse cursed technique in the aftermath of his defeat; his newly awakened skill cannot undo Riko’s death.

After learning to heal himself with reverse cursed technique, Gojo confronts Toji again. He demonstrates Red and then Hollow Purple, which combines the applications of Blue and Red. He kills Toji, but the victory is no rescue of the person he had been assigned to protect. Before dying, Toji mentions his young son Megumi and the Zenin clan’s interest in the boy, a revelation that gives Gojo a responsibility beyond the immediate battle.

A year later, Gojo can routinely complete assignments alone, while Geto grows increasingly disillusioned with the duty of protecting non-sorcerers. After Geto kills civilians and defects from Jujutsu High, Gojo confronts him but cannot bring himself to kill his former friend. Their partnership, once central to both of their lives, ends without reconciliation.

Gojo later seeks out Toji’s son, Megumi. He explains the Zenin clan’s interest in Megumi’s inherited potential and asks whether the boy wants to join that family. Megumi’s concern is for his stepsister Tsumiki, not the clan’s status. Gojo promises to handle the situation and encourages Megumi to grow stronger. Their later teacher-student bond begins with that intervention, not with an ordinary first day at Jujutsu High.

Gojo’s history with Geto comes to a final reckoning in Jujutsu Kaisen 0. After helping Yuta face the curse bound to him, Gojo must respond when Geto attacks the school to seize Rika’s power. Yuta defeats Geto, leaving him badly wounded; Gojo finds his former friend and kills him. The story does not reveal the exact words Gojo speaks to Geto just before his death.

At Shibuya Station, enemies use crowds of civilians and transfigured humans to limit Gojo’s options. He fights Jogo, Hanami and Choso while trying to avoid indiscriminate casualties, briefly opening Unlimited Void to incapacitate opponents without sustaining its full effect on the surrounding crowd. The opponents’ underlying plan is not to overpower Gojo in open combat, but to delay him long enough to activate the Prison Realm.

A figure with Suguru Geto’s face then appears, disrupting Gojo’s concentration at a crucial moment. The body belongs to his dead friend, but the person controlling it is Kenjaku, a sorcerer who inhabits other people’s bodies. Gojo is sealed in the Prison Realm. His absence leaves his students and allies to face escalating threats without the defender on whom jujutsu society has long relied.

Hana Kurusu and the Angel’s technique eventually enable Gojo’s release from the Prison Realm. He prepares to confront Sukuna, who now controls Megumi Fushiguro’s body. Their battle repeatedly pits Unlimited Void against Malevolent Shrine, taxes both fighters’ recovery abilities and forces Gojo to contend with Mahoraga’s adaptation to Infinity.

Despite periods when Gojo seems to be winning, Sukuna uses Mahoraga’s adaptation as a model for a slash that targets the space Gojo occupies rather than merely attempting to travel through Infinity. Gojo is killed in chapter 236. His death is neither another imprisonment nor a temporary vanishing act.

Chapter 261 briefly makes it look as though Gojo has returned. The figure on the battlefield is his body, but the sorcerer acting through it is Yuta Okkotsu. After copying Kenjaku’s body-transfer technique, Yuta undergoes the transfer with Shoko Ieiri’s medical assistance as a desperate measure against Sukuna. Yuta later returns to his own body; Gojo himself does not come back to life.

In the final chapter, Yuji remembers a conversation with Gojo from before the fight with Sukuna. Gojo hoped his students would develop strengths and judgment of their own rather than spend their lives trying to reproduce him. Yuji’s decision to offer a repentant curse user a second chance echoes that hope. The original manga ends without resurrecting Gojo; his last appearance is a memory, and his students carry forward the work he entrusted to them.
