No, Maki Zenin does not die in Jujutsu Kaisen. Despite suffering devastating injuries during the Shibuya Incident, she survives and later plays a crucial role in reshaping the power dynamics of the sorcerer world.
Shibuya Incident: Maki's Critical Injury
During the intense Shibuya Incident arc, Maki joins the battle against the special-grade cursed spirit Dagon alongside Nanami, Naobito, and Megumi. Although Toji Fushiguro’s sudden appearance helps eliminate Dagon, the aftermath turns tragic. Jogo, another powerful curse, attacks the group with a fatal burst of flames. Maki is gravely injured—burned and left unconscious.
Outcome:
Though the anime initially leaves her fate ambiguous, the manga confirms her survival. However, she is left with significant burn scars and reduced physical ability—at least temporarily.
Mai’s Death and Maki’s Transformation
In the aftermath, Maki is taken to recuperate. During this period, she reconnects with her twin sister, Mai Zenin, who makes the ultimate sacrifice to awaken Maki’s full potential. Mai dies in a cursed realm created by their clan, giving Maki a sword and transferring her innate ability to see curses naturally—without glasses.
Key impact:
This moment marks Maki’s rebirth. Now on par with Toji Fushiguro’s physical prowess, she becomes a "monster" without cursed energy, immune to many cursed techniques.
The Fall of the Zenin Clan
Fueled by Mai’s death and years of abuse from the Zenin clan, Maki returns to the Zenin estate. In a single night, she kills every member of the clan, including her father and top-ranked sorcerers, enacting long-awaited revenge and fulfilling Mai’s dying wish.
Relationship with Yuta Okkotsu
Though some fan sources like Game Rant speculate about a future romance between Maki and Yuta Okkotsu, the manga has not explicitly confirmed a romantic relationship. What is clear is that they share deep mutual respect and concern for each other.

She survives the Shibuya Incident, albeit with major injuries.
