Unlimited Void

is Satoru Gojo's domain expansion using the Limitless.
== Description ==
Befitting its name, Unlimited Void brings the user and their targets inside the Limitless itself, which is an endless void resembling outer space in appearance, with a large black hole, distant galaxies and numerous white patches in the background. Boundless raw information floods into the target's mind, overwhelming them to the point where they're completely immobilized. Alongside Self-Embodiment of Perfection, Kento Nanami considered Unlimited Void an almost-guaranteed win once it ensnares its target. 
The complete incapacitation of the target is caused by a phenomenon where the target will be able to see and feel everything while not being able to see or feel anything at the same time. All the actions one has taken in their life is forced upon them infinitely and they can't do anything but die slowly. This effect does not affect the user or anyone they're touching, whether willingly or not, which can be exploited by an opponent to become immune to the domain expansion's effects.
== Usage ==
 
Unlimited Void is one of, if not the most advanced technique in the arsenal of the Limitless. Satoru Gojo inherited the Six Eyes and likely mastered his Domain Expansion after awakening his full potential after the Star Plasma Vessel escort mission. He first displayed his mastery over his domain when he used it to counter Jogo's Coffin of the Iron Mountain. Unlimited Void was the more refined of the two domains and easily suppressed Coffin of the Iron Mountain. 
Being trapped inside the Limitless left Jogo in a complete trance, to the point where he couldn't move at all and could hardly think clearly. He could only think of how he was helpless due to the endless information invading his mind. Satoru divulged how Unlimited Void forces one's actions upon them infinitely and noted how it was ironic how the target is given everything and yet unable to do anything at all. 
 
When Kenjaku was explaining his plan to seal Satoru with Jogo, a part of their strategy to use non-sorcerers to hinder his techniques was meant to prevent Satoru from casting Unlimited Void at all. They assumed Satoru is skilled enough to exclude anyone he's not targetting from his domain. However, doing so during the Shibuya Incident could've crushed the bystanders between the domain's barrier and the curtain trapping Satoru. Kenjaku was 99% sure Satoru wouldn't cast his domain and reminded Jogo that no one on their side could cast theirs either as that would leave Satoru no choice. 
 
During their actual fight with Satoru, Mahito and Jogo were confident their adversary wouldn't sacrifice the bystanders' lives to cast his domain. Although Satoru could have exorcised every curse with Unlimited Void, everyone else would've died too. Instead, Satoru surprised everyone and activated an all-or-nothing Domain Expansion of just 0.2 seconds. The time frame was just a guess that Satoru made, figuring that a non-sorcerer could only last 0.2 seconds within the domain without suffering aftereffects. The amount of information that everyone was exposed to was about half a year's worth, leaving everyone unconscious while still standing. This level of the domain could've allowed the cursed spirits to awaken from their trance at any moment, so Satoru focused on eliminating all one thousand of the transfigured humans targeting the civilians in just 299 seconds.
During Satoru's duel with Sukuna, he expanded Unlimited Void a total of five times. The two fighters simultaneously activated domain expansion early in the fight after a brief physical exchange. Unlimited Void proved to be as equally refined as Sukuna's Malevolent Shrine, resulting in an even domain clash where both of their guaranteed hits were neutralized. However, Malevolent Shrine's barrier is open and its range is far superior to Unlimited Void's. Most domain barriers are weak externally as a trade-off for being reinforced internally and Unlimited Void is no exception. The constant slashes from Malevolent Shrine to the outside of Unlimited Void's barrier caused it to collapse.
After surviving an onslaught from Malevolent Shrine, Satoru found a way to recover his exhausted cursed technique and expanded his domain for a second time. Satoru used his mastery over sorcery to switch the internal and external conditions of Unlimited Void to protect it from the slashes to its outer shell. The barrier initially held out but Sukuna countered by using a binding vow to cancel out his sure-hit effect while narrowing the range of his domain to strengthen the slashes and once again shattered the domain.
Better prepared for the scenario, Satoru used Falling Blossom Emotion long enough to restore his technique and then expanded Unlimited Void for the third time. Using the knowledge gained from his time trapped inside the Prison Realm, Satoru narrowed his domain's outer shell down to the size of a basketball, further increasing the density and toughness of the barrier. Sukuna once again countered by narrowing Malevolent Shrine's range in exchange for increased output, the denser barrier survived the barrage of slashes for three minutes before collapsing. This gave Satoru enough time to damage Sukuna to the point where he couldn't maintain his domain either, leading both domains to fail at the same time. 
Both Satoru and Sukuna recovered their exhausted cursed techniques using reverse cursed techniques and then expanded their domains at the same time. This fourth clash led to the same result as the third, with both domains collapsing at the same time. In the fifth and final clash between Unlimited Void and Malevolent Shrine, Sukuna was just slightly late in opening his domain. The difference was less than 0.01 seconds but it was long enough to immobilize Sukuna for just a moment. This was enough time for Satoru to severely injure Sukuna with a single strike. They fought for two minutes and forty seconds before Malevolent Shrine collapsed as a result of Sukuna's extensive injuries, allowing Unlimited Void to completely incapacitate him. However, before Satoru could capitalize, Sukuna summoned Mahoraga and the shikigami immediately destroyed the domain. 
Sukuna revealed that he had Megumi's soul take the brunt of the past five Unlimited Voids to help the process of adaptation for Mahoraga. While having to repeatedly replenish his burnt-out cursed technique with reverse cursed technique proved too much for Satoru to activate Unlimited Void a sixth time, Unlimited Void also managed to previously damage Sukuna for a total of less than ten seconds before it was destroyed, damaging his brain to the same level as Satoru and disabling his ability to cast Malevolent Shrine for the remainder of the fight.
