In the midst of his battle with Jujutsu Kaisen’s Itadori, Higuruma eventually reveals his Cursed Technique; he uses his Domain Expansion immediately to trap Itadori.\n\nSpeculation has surrounded Hiromi Higuruma's Cursed Technique since the character was introduced in Chapter 159. While he has previously amassed 100 points in the Culling Game, an explanation for how he did so has been kept under wraps in previous chapters. Yuji Itadori hoped that Hiromi would hear him out and agree to aid him when he found the lawyer-turned-murderer in the previous chapter in a theater.\nAs a result, Hiromi has no interest in Yuji's suggestion to introduce a rule that would prevent the Culling Game's forced killing and even less patience for the hero's plans to stop the game. In his heart of hearts, he thinks the Culling Game is fantastic. Negotiations with Hiromi have failed, so Yuji has no choice but to use brute force to convince her. In this way, the stage is set for the eventual battle.\n\nThere are roughly 20 sorcerers Hiromi has murdered so far, according to Yuji. Five points are awarded to sorcerers, while one point is awarded to all other players. Of course, he doesn't know for sure if his adversary has solely murdered sorcerers. Yuji decides to wait for Hiromi to make the first move because of all the unknowns. What could have been a great idea at the time turns out to be a disastrous one. In the beginning, Hiromi's move is the one sorcerers dread the most: Domain Expansion. In the blink of an eye, it becomes quite evident that Hiromi has no qualms about assassinating Yuji.\nAnyone who understands Hiromi's past as a lawyer would expect his domain, which he calls Deadly Sentencing, to look like a court chamber. It's too late for Yuji to get a shot in before his technique is fully activated. Hiromi and Yuji will not be allowed to engage in any kind of violence in this domain. Verbal violence, on the other hand, is not covered by this rule.\nHiromi's shikigami, which he refers to as Judgeman, puts Itadori on trial. Because he's under 18, he's breaking the law by entering a gambling establishment. While Judgeman knows everything about everyone in the Domain, he doesn't share any of this information with Hiromi. When it comes to making decisions, Hiromi has Judgeman's tiniest bit of evidence to fall back on.\n\nCompared to previous Domain expansions, Hiromi's Domain Expansion appears to have a very different approach. Trapping an opponent in a Domain was largely used before Chapter 164 as a means of ensuring that the user's attacks would hit and likely kill. Even more so, the user's attacks become more powerful outside of the Domain. For the first time, a Domain that prohibits violence opens the door to more inventive Cursed Techniques.\nSeeing Hiromi's Domain brings back memories for Yuji of something Master Tengen had shared with him: Domains were more widespread among sorcerers in the past than they are today. Many Domains today use lethal, hyper-accurate attacks, but this wasn't always the case. It used to be that domains were only a means of forcing targets to follow the Cursed Technique's laws.\nCreating a fatal Domain demands a great deal of skill. A decline in user numbers is due to this. Those in Hiromi's Domain can't physically damage each other, let alone kill each other, therefore it's a very old-fashioned place. As a result, it requires an explanation of the rules as well as a binding pledge.\nHe explains to Hiromi that they both have a limited amount of time to make an impression. If Yuji wants to be found innocent, he must make his case and clear up any lingering doubts. Hiromi's speech will provide a counterpoint to Yuji's, and then Judgeman will make a decision based on the evidence he has. However, he does inform Yuji that there are three ways he can respond if proven guilty: quiet, confession, and denial. The denial, he adds, may contain things that aren't true. Yuji carefully weighs all of his options in light of the enigmatic facts.\n\nEventually, Yuji admits that he entered the parlor, but claims that he merely went there to use the lavatory, when in fact he gambled. To support her claim, Hiromi provides a picture of Yuji at a nearby cash exchange window. According to him, the only thing Yuji had to do to defend himself was to state that he'd never heard of the parlor in question and deny the accusation. A problematic situation in which Yuji mistakenly confesses because he didn't know that the crime is the only unauthorized entry, resulting in his own death.\nYuji is found guilty and sentenced to confiscation by the judge. Finally, the Domain has been deactivated and they're back in the theater once more. Hiromi swings his gavel at Yuji as soon as he sees him. For example, he is able to make the gavel appear or disappear as well as vary its size. After a few blows to the face, Yuji knows what Judgeman has taken from him: Despite his best efforts, he can't seem to keep his Cursed Energy under control.\nClearly, Hiromi's Cursed Technique is capable of a lot more. Because of his innate strength, Yuji will be able to fight without the need of his Cursed Energy. If the battle becomes hopeless, he'll either have to win as he is or find a way out. However, he will have to face Hiromi in order to retrieve his Cursed Energy at some point in the near future. Sukuna may also be able to assist in some way. After all, he wouldn't let his ship go down without a fight.
