Fans have never forgotten Gege Akutami’s biggest oversight: the lack of a full explanation for Yuji Itadori’s Domain Expansion. Now, Jujutsu Kaisen Modulo promises to fix this gap as Yuji returns as the strongest sorcerer in the world.

Yuji’s Domain Expansion: The Biggest Unresolved Mystery
Let’s revisit the brutal final battle against Sukuna. Yuji finally cornered the King of Curses in a one-on-one showdown, setting the perfect stage for the long-anticipated debut of his Domain Expansion.

Yuji’s Domain gave Sukuna fleeting glimpses of memories, familiar places, and intense emotions like a rapid montage of cursed images. Yet, the manga never explained anything, no name, no mechanics, no confirmation that it was a type of cursed technique, and nothing about how it nearly turned the tide against Sukuna.
For fans who analyze every detail of Jujutsu Kaisen’s characters, this was a serious omission. It became one of Akutami’s biggest storytelling mistakes, not because the idea was bad, but because it was never fully developed.
Jujutsu Kaisen Modulo Teases a World-Changing Power
Jujutsu Kaisen Modulo takes place sixty years after the original timeline. Somehow, Yuji Itadori is not only alive but thriving. This nearly 80-year-old man looks barely over thirty and is comfortably labeled the strongest sorcerer on Earth. In fact, Yuji’s “anti-aging” technique is even more astonishing than Gojo’s Six Eyes.

Yuji’s brief, mysterious appearances in Modulo have built huge anticipation for a major reveal. It’s clear Akutami had a big plan bringing him back. Every scene is a clue leading to what Jujutsu Kaisen never fully delivered, the full power of Yuji’s Domain Expansion.
Yuji has had over sixty years to refine any unfinished techniques he used against Sukuna. His new status as the world’s strongest sorcerer and a key political figure in Japan’s relations with the Simurian tribe proves he is now a “sorcerer monster.” If he unleashes his Domain again, it won’t be a half-baked emotional flashback.
Ultimately, Yuji doesn’t need to be the main character in Jujutsu Kaisen Modulo to make a huge impact. His Domain Expansion remains one of the last core mysteries. With pressure from the community, Akutami is unlikely to leave this crucial detail unresolved a second time.
A full reveal would elevate both the sequel series and the original story, giving fans closure, cementing Yuji’s ultimate evolution, and possibly rewriting everything we thought we knew about his abilities. The stakes are high, not just for Modulo but for Yuji’s legacy. Honestly, that’s exactly why this reveal is inevitable.
