To think that Satoru Gojo's Cursed Technique—of all things—was actually outmaneuvered by Sukuna... it's frustrating just to think about it.
The true nature of Infinity Void was never fully brought into play, and an open domain is far from completely unbeatable.
Gojo clearly prepared seriously for the fight, yet he still had all kinds of tactical flaws—it feels like the author did it on purpose.
With Gojo’s innate talent for jujutsu, it’s strange that right before fighting the King of Curses, he never fixed the vulnerability in his domain regarding physical contact immunity. Could it be that everyone’s domain has this self-injury loophole? For mental attacks, he could simply limit the immunity effect to only protect the brain.
Sukuna was also extremely reckless. He never worried that Gojo might adjust his tactics during preparation, and ended up getting defeated by his own outdated intelligence.
Sukuna’s open domain was already destroyed from the inside by Gojo once. That’s the only fair balance.
A closed domain has a barrier on the outside with boundless space inside; its shell exists externally.
An open domain relies on a attached shrine. Heavy concentrated attacks can still shatter it. It can be seen as an enhanced version of a domain barrier, just compressed from the outer edge toward the center.
Trying to have everything at once goes against the logic of narrative balance. It simply doesn’t work, otherwise the plot would never make sense.
Also, the modern Simple Domain only lasts a short time per cast. You can move freely and use jujutsu in the duration, but there’s a cooldown gap before recasting.
The ancient Buddhist Cage Technique coordinates cursed energy through hands, mouth, and mind with seamless activation. Still, it should collapse instantly once interrupted.
You can’t have both permanent duration and free movement at the same time. If that were allowed, there would be no tension left at all.
Sukuna already has four arms—he can maintain the cage, move around, and cast jujutsu simultaneously. If the cage could stay active automatically for a while on top of that, modern Simple Domains would be completely useless with terrible overall performance.
Is it really a case of later generations being weaker than the old ones? Just like Jin Yong’s wuxia lore, every generation keeps holding back their true skills, leading to the gradual decline and withering of inherited
