Understanding the Simple Domain Concept in Jujutsu Kaisen

Jujutsu Kaisen features a variety of unique techniques, some of which wield incredible power. One such technique, created by Ahiya Sadatsuna in the Heian Period, can compete with the efficacy of Gojo’s innate Six Eyes technique.

The Simple Domain technique functions as both a barrier and an anti-domain. In contrast to traditional domain expansions, which assure a hit on the opponent, the Simple Domain has the ability to nullify those expansions. Its versatility adds to its value.

During the Golden Age of Shamans, a period marked by significant advancements in Jujutsu, Ashiya Sadatsuna developed the Simple Domain technique to shield his disciples from malevolent curses and sorcerers.

This technique has been utilized by notable characters such as Mechamaru in battle against Mahito and Kasumi Miwa when confronting Maki. Yuji has also showcased this technique against Sukuna.

The New Shadow Style: Simple Domain is introduced in the earlier episodes of Jujutsu Kaisen, particularly during the Goodwill Event Arc, when Kasumi Miwa attempts to attack Yuji.

As more characters adopt the Simple Domain technique, its execution showcases increasing versatility and potential.

Even cursed spirits within the series are shown to employ the Simple Domain, although there are risks associated with its use, as weaker spirits have sustained injuries and backlash damage after attempting this technique.

How does Yuji use the Simple Domain?

Yuji Itadori learned to harness the Simple Domain one month prior to the climactic confrontation with Sukuna. This knowledge came through a technique involving soul swapping with Atsuya Kusakabe during training. He successfully utilized this anti-domain strategy to shield himself from Sukuna’s Malevolent Shrine.

Despite not being part of the Sadatsuna lineage, Yuji learned the Simple Domain by swapping bodies with Atsuya Kusakabe, who was already capable of using the Domain. Yuji concealed this ability as a contingency plan for dire situations.

The Simple Domain sustained and resisted domain attacks for nearly 99 seconds, marking a substantial achievement within the broader conflict.

It’s notable that Yuta faced severe peril shortly after Gojo’s return, underscoring the danger associated with Jujutsu battles. The Simple Domain, part of Sadatsuna Ashiya’s teachings, had been restricted from being shared with outsiders.

Yet, in modern times, several sorcerers without lineage connections are able to utilize the Simple Domain. For instance, Kasumi Miwa, trained in Junior High by her mentor, and Aoi Todo, who received instruction from Yuki Tsukumo despite not being from a sorcerer family.
