The Jujutsu Kaisen Modulo Sukuna alien theory is shattering everything we thought we knew about the King of Curses. Set 68 years after the original series, this official sequel introduces the Simurians—an extraterrestrial race that might just be Sukuna’s long-lost kin.
From the mysterious spaceship Naunax to the striking physical parallels between the aliens and Ryomen Sukuna, the evidence is piling up. We’re breaking down the “Insider” details on Yuta and Maki’s legacy, the new alien threat, and why Gege Akutami is likely revealing Sukuna’s true extraterrestrial origins.
What is the Jujutsu Kaisen Modulo Sukuna alien theory?

The core of the Jujutsu Kaisen Modulo Sukuna alien theory suggests that Ryomen Sukuna was never fully human, but rather a Simurian or a human-Simurian hybrid. In the new sequel set in 2086, protagonists Yuka and Tsurugi encounter Maru, a Simurian ally with facial markings that are a near-perfect match for Sukuna’s iconic tattoos.
- The Twin Parallel: Maru has a cold, dismissive twin brother, mirroring Sukuna’s backstory of consuming his own twin in the womb.
- The Fallen Angel: This theory finally explains why Sukuna was called the “Fallen Angel”—he literally fell from the stars.
- The King’s Pose: The King of the Simurians is depicted sitting on a throne in a posture identical to Sukuna’s Domain Expansion stance.
How does the Naunax spaceship confirm the Sukuna connection?
One of the most damning pieces of evidence for the Jujutsu Kaisen Modulo Sukuna alien theory lies in the name of the Simurian mothership: Naunax. Eagle-eyed fans have realized that “Naunax” (ナウナクス) is an anagram; the last three characters spell “Sukuna” (スクナ) backward in Japanese.
This isn’t just a coincidence—it is a deliberate breadcrumb left by Gege Akutami. If the alien mothership itself bears his name, it strongly implies that Sukuna’s “cursed” nature was actually a dormant alien bloodline rejected by humanity during the Heian Era.
Who are the new protagonists Yuka and Tsurugi?

Leading the charge in Jujutsu Kaisen Modulo are Yuka and Tsurugi, the grandchildren of Maki Zen’in and Yuta Okkotsu. The story confirms that Yuta and Maki lived a full life together, with Yuta passing away from exhaustion shortly after Maki’s death due to their bonded cursed energy.
- Yuka Okkotsu: She wields Rika’s ring and is determined to prove herself as the worthy heir to Yuta’s immense power.
- Tsurugi Okkotsu: Like Toji and Maki, he possesses a Heavenly Restriction with zero cursed energy and rejects the family’s expectations.
What are the Simurians and their cursed energy powers?
The Simurians are an alien refugee race seeking asylum on Earth, and their arrival has triggered a global crisis managed by Japan’s sorcerers. Unlike typical sci-fi aliens, Simurians can manipulate cursed energy just like human sorcerers, bridging the gap between occult lore and extraterrestrial life.
Their ability to use cursed energy supports the theory that the “source” of cursed energy might not be unique to Earth. If Sukuna is indeed a Simurian descendant, his overwhelming cursed energy levels and four-armed form would be biological traits of his species rather than just a mutation.
The Verdict: Is Sukuna Truly an Alien?
The Jujutsu Kaisen Modulo Sukuna alien theory is more than just fan speculation; it is the narrative engine driving this sequel. With the Naunax anagram, the twin parallels, and the introduction of Yuta and Maki’s descendants, Gege Akutami is weaving a sci-fi twist that recontextualizes the entire franchise. As we watch Yuka and Tsurugi face this interstellar threat, we are likely witnessing the true history of the King of Curses unfold.
