this guy asked me to Explain domain expansions so I made a super in-depth guide on barriers as a whole instead you won't learn how to do your taxes contribute to a 401k make money cook clean or any other important life skill really but hey at least you'll learn what a barrier in a fictional show is speaking of which what even is a barrier a barrier is defined as a zone or territory with a primary goal of concealing containing or denying entry to anything within that space in Jutsu kaisen barriers have some variance with their shapes
and sizes but the vast majority are spherical on the other hand the effects that they can have are near infinite the most basic applications of a barrier that we see are curtains typically used by assistants like ich these barriers serve to hide the actions of jiujitsu sorcerers from the outside world with non Sorcerers being the main reason that Cur Spirits exist in the first place it is imperative that these curtains are deployed so as to not disturb the piece the curtains take a snapshot of the environment and project that imagery to normies all the while
inside the curtain the sky darkens and cursed Spirits are lured out of hiding making it easier for the Jutsu sorcerer Within to exercise them swiftly and most importantly secretly to cast this kind of barrier Sorcerers must usually recite the following incantation emerge from the darkness blacker than Darkness purify that which is impure while this is the most basic form of barriers that we see it doesn't mean that it's weak or only useful for secretly exercising curses like I mentioned a moment ago barriers have a near infinite number of effects that they can have through the
use of binding valves curtains can accomplish much much more than just Hideway cursed energy in the Goodwill event Arc for example kinjaku creates a curon with a simple condition everyone is allowed to enter and leave as they please everyone other than Gojo to the powers of be in the world of jiujitsu kaisen the trade-off is seen as fair and the effect can actually take place additionally barriers can be cast and strengthened through the use of talismans in Shibuya Kaku has curse users and curse Spirits play Stakes imbued with a powerful barrier technique around the area
allowing even weaker Sorcerers that lack his knowledge to cast ridiculously Advanced barriers regardless the trade-off in this case is that they must be put in super obvious spots like at the top of the tallest building or in the middle of the station for example simple domain created by satuna Asia at the height of the hyan era and app named a domain for the weak this barrier technique primarily allows the user to fight back against domain expansions the technique itself Works similarly to a domain expansion with it creating a small barrier around the user the barrier
disrupts the sure hit of the domain expansion giving the Caster a moment to breathe and fight back while this might seem incredibly powerful on paper it doesn't necessarily guarantee safety to its creator against the real domain one can only hope to buy a little time before their simple domain inevitably crumbles even Yuki a special grade on par with UT kotu was unable to maintain her simple domain for more than a few moments against a real domain simple domains don't technically have curse techniques imbued inside them they can however be customized through binding Valves and rules
with visualization being an important aspect to sorcery we get to see a variety of uses for simple domains throughout the series the most basic form that we see is the Quick Draw that both miwa and kusak Caba used to varying success the user expands their simp simple domain and firmly plants their feet their sword is imbued with cursed energy and once anyone enters the range of the domain the user is able to automatically attack them with quick speed and precision outside of quick draw simple domain can also be used defensively in the Shibuya Arc kusakabe
uses it to block maximum Uzumaki a feat that leaves even Kaku impressed more advanced forms of simple domain include kuchisake Ona a curs spirit whose simple domain stops time and enforces a rule of nonviolence until her question is answered once the target of the domain answers the question the ability activates and pairs of scissors spawn on top of the target ready to tear them to shreds in more recent chapters Roku jushi Mio AKA sumo guy deploys his simple domain a Sumo ring is created and for the full barrier to be formed both parties must agree
to the Sumo match beforehand the domain strips away all aspects of jiutu leaving only one thing to do Sumo on top of eliminating all elements of jiujitsu binding vows time inside the domain flows differently in the time that it takes him and his opponent to complete over a th000 belts less than a minute passes outside the barrier Hollow wicker basket the predecessor to simple domain Hollow Waker basket is an inferior anti-d domain technique functionally it's able to counteract Shad of a domain but the user must use both hands in order to cast it recent chapters
make it seem like the user must have their hands clasped together at all times to maintain the technique but with it having only been used twice in the series it's actually hard to say whether that's necessary or not when meami expands his domain against Reggie star Hollow wicker basket is used by Reggie he clasps his hand together to form the barrier but once he realizes that meam don't make is incomplete and thus lacking in a sh hit he lowers his hands but Hollow Waker basket remains for another page before Reggie gets his kicked in from
megamy and knocked out and away from the basket huge spoilers for recent chapters so if you're not cut up skip to this timestamp when sukuna uses Hollow wicker basket the reason that he must maintain it by keeping his hands classed together is different to that of Reggie if sukuna simply uses the technique and then freeze his hands he runs as the risk of the basket shattering and then being hit by Jacob's Ladder before getting a chance to recast the technique we see that they'd already plan on him doing just that so it wouldn't surprise me
if that's what sakuno was thinking as well point is we don't 100% know whether Hollow Wier basket needs both hands to be classed at all times or if it can be activated once and then used until it shatters just like Yuki and Gojo's simple domain additionally we haven't seen the technique be used in tandem with binding vals or rules so as it stands it's straight up just a worst version of simple domain on the topic of worst versions of simple domain falling Blossom emotion is another anti-d domain technique that kind of sucks falling Blossom emotion
thinly coasts the user in cursed energy that counter sure hits at the moment of them materializing I call it bad because the user must stand still can't use their hands and it only really works against more simple techniques that can be directly parried it might deflect dog On's fish but it wouldn't stop a complex ability like unlimited void from cooking you on the spot ultimately though it does have its uses so I guess I won't discredit it entirely domain amplification essentially to use domain amplification the user must envelop their body with a thin veil of
their own domain this allows the user to neutralize the enemy curse techniques and domain expansions a very powerful technique its natural give and take is equally brutal in exchange for being granted the ability to bypass even the Limitless the usage of one's curse technique becomes impossible so long as domain amplification is active subscribing to channel barriers the advanced form of Shameless plugging stopping the video halfway through to let you know that a like or a subscription is greatly appreciated is only doable by the most Shameless Advanced barriers with Tangen being the best barrier user in
the entire series it's no surprise that their barriers are among the most advanced as well as the most prominent seriously tangan has their hand lands on practically everything a barrier that changes the layout and appearance every day to hide the school's existence from the public check barriers that conceal by manipulating over 1,000 doors that constantly shift to make sure that the entrance is always moving and hard to track check a final super duper secret barrier that only allows those invited to enter yeah okay tanging can do practically anything there are however three more advanced named
barriers that I briefly want to touch on before I move on to domain expansions empty barriers this to me is probably the most needlessly convoluted barrier at least trying to explain it in depth it's got some like vaguely philosophical elements to it and I'm by no means an expert that's why I called up ask yourself and asked him self to help me better explain this and and in Buddhism specifically there's a lot of this and emptiness is like going through theit try to figure this out a state of non-conceptual awareness so that's like a first
pass but yeah that's that's how I understand emptiness in the phenomenological sense okay never mind there's a lot we can get into but functionally all you need to know is that these barriers are made up of hexagonal shaped panels and the inside of the barrier is empty true emptiness this allows a sufficiently scaled enough barriers user to project whatever they want Within These barriers Tangen fills this emptiness with various different settings one moment they're sitting around having tea then 2 seconds later they're at a bar and tangan is serving up shake and margaritas on top
of that they also have a circular definition which means means essentially you can think of the barrier as serin's triangle and uh no I will actually not explain that because I'm not going to indulge in G's 3:00 a.m Coke fueled Wikipedia escapades so that's all you're getting from me for this one pure barriers these barriers are stronger than the empty ones and it makes perfect sense these are barriers that tangan uses to help strengthen the efficiency of basic barrier techniques all throughout Japan as well as help suppress the outbreak of curses there are four super
important ones one in the Imperial Palace one in the Tomb of the star where R got goded one in the yamakuni mum and Kyoto and the largest one at the Holy Mountain of Heda well that's all we know about him Bond barriers using pure barriers as a base kjak is able to further strengthen those barriers and create a new much stronger version that he uses to create the calling games as a result if the original pure barriers were to fall so too with the bond barriers thus forcefully ending the culling games downside however would be
throwing away a thousand years worth of progress in The NeverEnding battle against curses make of that what you will domain expansion the Pinnacle of jiujitsu combat domain expansions are what all jiujitsu Sorcerers can strive for but not all can achieve simply put a domain expansion is the act of bringing forth one's innate domain and imbuing it with a curse technique and then enclosing it inside of a barrier an innate domain can be better explained as a mental landscape both Sorcerers and non- Sorcerers have one as it's supposed to be the embodiment of one's inner heart
it's why curse techniques often reflect their users as well as the foundation for one's domain Jo goat's coffin of the Iron Mountain is a living breathing volcano whereas mahito self- embodiment in Perfection puts you in the literal palm of his hand Str Al domain expansions are strong on the inside making it nearly impossible to break out of conversely however the outside is far weaker after all who would be stupid enough to break into certain death once inside the domain the casters granted a passive increase to their stats just like a buff in a video game
while the buff is nice the real prize is the sure hit once a domain is fully formed all attacks within the barrier are guaranteed to hit the target these attacks cannot be blocked but a lot of them can be resisted naito nanami and Moi all survive varying levels of dogon onslaught despite them being continuously hit with no ability to defend themselves outside of cursed energy reinforcements more abstract sh hits like mahito or gojos make defending against it impossible outside of using something like Hollow wicker basket or simple domain incomplete domains an incomplete domain is exactly
what it sounds like domain expansions that lack something cimara Shadow Garden is the one major domain in the series that fist this description the domain lacks both an outer shell and a sure hit for Megami the domain acts more as an extension of of his technique rather than its own ability despite this Megami still gets the passive benefits of a domain allowing him to fight at 120% of his strength and if he finds himself in an enclosed area he can use his surroundings to forcibly close the shell of his domain modern and old style domains
modern domains are explained as having a larger focus on their lethality they serve as fight Enders and have evolved accordingly in both scope and scale with such stringent conditions modern domains became harder to master old school domains on the other hand were a lot less lethal instead forcing the opponent to abide by their rules of the curse technique as a result they were a lot more common and likely used up less curse energy most domains we see are modern so I'll just use unlimited void as the example unlimited void is goo's domain expansion and once
within the domain everyone caught by the sh hit will have their brain filled to the brim with an endless stream of information this effectively leaves them unable to move slowly dying as their brain struggles to keep up with the information even just 2 seconds of unlimited void was barely enough to not instantly kill all the humans in the train station and even Joo a curs spirit who should have some res resistance to it was immediately stunned without any counterplay huruma homi's deadly sentencing on the other hand is an old style domain for the effect of
the domain to actually take place huruma must first explain the rules of the domain allow the trial to take place and find his opponent guilty before judg man can actually have a real physical effect in this case the bang of the gavel on the sound block reverberates throughout the trial room and the punishment of confiscating one's curse technique and ultimately the death penalty can be served Divine domains the truly Divine domains are those that do not have a barrier like painting without a canvas directly onto the air itself sukuna projects his innate domain onto the
world slashing and cutting anything in a 200 met radius what makes these types of domains nearly impossible is the premise itself how would you hand someone water from a water bottle without the water or how would you paint onto the air itself without a canvas visualizing such a ridiculous feat and then being able to act upon it is what makes these types of domains so special they're so unique that to date only two of the 16 domains in the series are the ones that don't have a barrier megies domain doesn't technically have one either but
that's because his domain is in complete not exactly an intended feature domain clashes and the aftermath The Clash of domains is pretty straightforward when two opposing domains are cast the barriers Collide in a battle for Supremacy over the Shad begins during a clash the sh head effect of both domains is neutralized and the domain with better refinement ultimately wins out curs energy amounts and compatibility a little bit more on that later also play a small role if two domains are evenly matched the battle continues until one side is no longer able to maintain the domain
either by bodily injury or lack of curse energy the winning domain then takes over and the sure hit is immediately reinstated in Shibuya doon's domain was challenged by that of megum and so long as meami was able to maintain his domain the sure hit of dog guns shikigami was disabled allowing for the gang to Counterattack and also make their escape that however is only the standard interaction between two domains If instead three domains are GED simultaneously the conditions of the barriers are simply too incompatible and the maintaining the barriers becomes n impossible we've only seen
one instance of a three-way domain expansion but it was interrupted by a fourth party shortly after The Clash started the narrator tells us that a clash of domains is already complicated and adding a third one to the mix is insanity this likely implies that a 3way clash is unsustainable and that the barriers may all break naturally because of their variance open domains versus closed ones we've only seen one Clash like this so far in the series but the advantage that open domains have over standard domains is that they often extend past the radius of the
normal ones this in turn allows the shood of the open domain to attack the outer shell uncontested meaning unless you can outright overwhelm the opponent's open domain your normal one will swiftly fall as it's weak to outside attacks once the domain shatters the user goes through curse technique burnout for a varying period of time after the domain is gone the user is unable to use their curse technique this has been a thing since the very beginning but it feels like gig has played fast and loose with it from time to time after maho's first domain
expansion he is quickly able to shift himself around and make his Escape meanwhile in more recent chapters he takes aari over 4 minutes for him to regain access to his curse technique G has always said that techniques become more difficult to use after domain expansion with how they're portrayed post Shibuya it feels like a soft redcon for now after domain expansion using a curse technique is impossible and the amount of time it takes to get your Technique back varies from person to person domain conditions the conditions of a domain is something relatively new in the
manga but has technically existed since the beginning domains being strong on the inside is a condition created by the sorcerer because the goal of a domain is to trap your opponent so giving up its outer durability completely in favor of its inner one is a clear give and take as such doing the opposite because it is also possible but not something that could be easily done by most Sorcerers the size of a domain can also be altered but shrinking into the size of a basketball is a feat that can only be done by Gojo because
of his experience in the prison realm what makes this difficult to pull off is once again the visualization aspect while domains are much larger on the inside one must still be able to visualize that bigger space you try imagining yourself and another sweaty man locked up in a basketball siiz sphere that's actually somehow bigger on the outside trying to imagine both things s multaneously is a little difficult two other applications that we've seen include the following specifically targeting once sure hit usually anything within a domain becomes a target for the sure hit Gojo's unlimited void
attacks everyone not touching him anyone inside maho's domain can be transfigured anti- Moon Palace halts the movements of all within it you get the picture a skilled enough sorcerer can theoretically exclude one or more people within the domain allowing them to jump the enemy while not risking the lives of their comrades if Gojo had been capable of defeat he might have wiped the disaster curses in shibba with little effort and finally my personal favorite moving coordinates yep you heard that right with enough skill a sorcerer can literally move the entire barrier from point A to
point B we've seen this used twice so far so this is all we really know regarding it but with visualization becoming more and more important gaygay must have been watching freerun I imagine it has something to do with seeing the domain in a different place that allows for this feat to be possible final note on domain conditions characters whose curse techniques are directly tied to their domains like aari and higuma have an easier time with changing conditions on the Fly While most Sorcerers have to worry about the creation speed of the barrier or its volume
aari and hikara can practically do it without thinking and with that you know all there is to know about barriers I think so go watch my JJ cus conceptions video and maybe learn even more about random things
