In Episode 29 of Jujutsu Kaisen titled "Premature Death," the story takes place one year after the events of the previous episode, in August 2007. The episode begins with Satoru Gojo, who has become the "strongest" Jujutsu sorcerer, working on automating his Jujutsu technique. He explains to Shoko Ieiri that he has developed a method to determine the danger level of an object based on its cursed energy, mass, velocity, and shape. This allows him to keep his limitless technique active almost continuously with minimal effort.

Meanwhile, Suguru Geto is shown struggling with his duties as a Jujutsu sorcerer. He is seen exorcising and absorbing cursed spirits, a process he describes as swallowing a dirty rag to wipe up filth. He questions his purpose and the value of non-sorcerers, hinting at a growing internal conflict.

The episode introduces a new character, Yuki Tsukumo, a special-grade sorcerer who does not take assignments and operates overseas. She shares her vision of creating a world where no cursed spirits are born, either by eliminating humanity's cursed energy or enabling all of humanity to control their cursed energy. She reveals that cursed spirits are not born from sorcerers, and if all humans were Jujutsu sorcerers, no curses would be born either.

The story takes a dark turn when it is revealed that Suguru has massacred an entire village, including his own parents. He justifies his actions by stating his intention to create a world with only Jujutsu sorcerers. This revelation shocks Satoru, who struggles to understand Suguru's motives.

The episode ends with a scene set in 2018, where Satoru is seen sleeping in a chair, surrounded by his students. Despite the dark revelations and escalating conflict, the episode concludes on a lighthearted note.
