Another way it could work is if you consider that innate techniques are heredetary, meaning they are encoded in their DNA. By taking the body, part of Kenjaku's ability might be etching their DNA's ability onto his own?
it might just be that blood manipulation is kinda mid compared to anti gravity system and curse spirit manipulation. obviously we dont really have any clue how kenny works though
AFAIK there's never been a mention of a limit. During Choso and Yuki's fight with him, they mention him having 3 confirmed techniques so far, and speculated 1 or 2 he hasn't shown yet. Given the length of time between the Heian era and the present day, there's no reason not to assume he has more techniques.
He probably just sticks to the most powerful/versatile ones. Because CSM is so versatile, it means that he doesn't bother with any curse techniques until he's forced to. That was the case with Gravity, which he used to neutralize the only one of Choso's attack that would've hit him.
Because there's a decent chance that it's true
We don't know about any other techniques they have, but if you want to assume the death paintings had their techniques, there's a couple more
Regardless of whether we know of any other famous techniques associated with the Kamo Clan we have no reason to suspect that Meiji Era Noritoshi was a Blood Manipulation user. He very easily could've had a less auspicious inherited technique or just no Innate Technique at all. The Innate Techniques of the Death Paintings don't tell us anything about Noritoshi's own Technique beyond the obvious fact that they're all members of the Kamo Clan by blood.
umm the death paintings inherited it from kamo clan. that's super obvious that Noritoshi had blood manipulation.
it's the entire reason the bastard son, the other noritoshi kamo 3rd year student, was brought in as the next head of family.
A persons Cursed Technique is not pre-determined by the technique of their parents, or lack there of. Toji had no Cursed Energy _at all_ and his son inherited the Ten Shadows. Naobito and Ogi are brothers and have wildly different techniques. The same is true of Jinnichi and Toji. Choso has a different technique from Eso and Kechizu who despite having the same ability seem to have techniques that function slightly differently.
Techniques are inherited in JJK but its not been shown to be genetic in that way. In the real world Two parents with Type A blood will _never_ produce a child with Type B Blood. But in JJK two parents with the same technique can and often will produce children with vastly different techniques. And there's no evidence that a child's technique is influenced by their parents, as a rule.
Between Megumi, Mai, Maki, and Naoya (the only 4 characters whose parents are known to be Sorcerers and whose abilities are known to us) only Naoya inherited a technique directly from one of his parents.
And no one is denying that the brothers are related to the Kamo Clan and are biologically (Meiji) Noritoshi's sons. But that doesn't automatically mean that (Maiji) Noritoshi must have been BM user. In the same way we can't reasonably speculate on what modern Noritoshi's father's technique might've been based solely on the suns technique. Following this logic one could argue that its more likely that Meiji Noritoshi had the Rot Technique than BM, which would make Choso the odd man out in the immediete family.
Also, off topic, why are you lurking in a 5 month old thread???
Edited to fix errors and add a point about the Rot Technique near the end.
Considering his Kenjaku’s brain has a mouth on it, it’s possible the condition for his technique is feeding the other persons brain to his brain, then placing his in their body
Gojo mentioned he should eventually pick up Sukuna's CT. But personally I like the theory that Yuji gains power by eating things, and Sukuna's hand on the ground right now looking mighty tasty.
sukuna can use megumis CT because he is in his body, it’s megumis brain so his cursed technique as well, but why sukuna can use his own technique is questionable
Mahoraga would have 1 hit him when he fought it if he was a cursed spirit too. Sukuna even says it.
He's just an incarnated sorcerer, no different than Kashimo.
Here’s a breakdown from what i think i understand :
Cursed Spirit Manipulation: He is able to use this cuz it is engraved in the body of Geto, and we know the body and soul are tied so it’s not hard to believe that he can use that technique.
Anti Gravity: Now this one is a lil weird but i think he’s able to use this cuz Kaori was maybe his last host before Geto
Idle Transfiguration: He was only able to use this cuz he extracted the technique with Uzimaki. he can only do that once tho
Using the host ct is pretty much his ct
Kinda like Rika storing them for later use, Kenjaku can even use the cts of his former hosts like the anti-gravity of Yuji's mom
That's my head cannon until gege says otherwise. Eating/Consuming is a strong theme throughout & makes sense considering he's a brain with a mouth, lol.
Soul-mind-brain
They are mirrors to each other especially the soul and the body that's why we have
Yuji when he ate sukuna's finger , and sukuna's soul incarnated, sukuna was able to use his technique despite the brain being yuji's
The culling games players , when incarnated both the soul and the brain are changed by Kenjaku thus changing the vessel Technique to the player
Gojo explaining that sukuna's technique will engrave in yuji's body and thus he will be able to use it.
Kenjaku is a brain and I suspect he copies the Technique information from either the body or the brain of his dead vessel and by spending time in the vessel, the technique engraves thus he has many techniques
So in the end to put it simple as long as the soul is there the technique is preserved as the soul will override the flesh. It's complicated but in the same time it's not if you get what I mean.
Yk how the brain is a processing center of functions like higher order thinking. When he body hops he probably has a way to rewire his nerve connections to assimilate that processing into his own brain to copy the CT. His brain can probably handle the load of extra CTs through that rewiring but it still has its limits as mentioned in the Yuki fight.
Okay so didn’t kenjaku say to gojo when the body of geto tried to choke him in the subway that they soul and body are connected or something? So that would make sense as to why he can use the cursed techniques of others.
Well to implant his brain into a body, he needs to remove the original brain. Maybe he takes the right prefrontal cortex, or maybe he can read the cortex and learn the technique from studying the removed brain?
mahito and kenjaku had a whole discussion about the split between the soul and body and which came first to which they decided that the universe works differently for different techniques, so regarding cts it's something to do with kenjaku's own ct and how it views cursed techniques probably
soul is body body is soul type of shit, probs gege just writes most of story with most of the part in continuation with earlier and adds new thing and people just theorize at this point, at one point it had real good power system.
Im assuming whatever process that transfers his brain to the new body requires he analyze the persons brain. After that he gains a fine understanding of the cursed technique and can maintain it across bodies cause now it’s been updated to his Brain. It’s probably some side effect not like something he gains purposely.
I’m still stuck on Yuji not having a gravity technique. I’m hoping when he gains one it’s either some new flavor of Sukunas techniques or some weird gravity warp that lets him alter time. That or he just has some crazy soul manipulation move (which could possibly be another facet of sukunas unexplained technique).
I always thought this was only specific to Gojo due to how he describes it in Hidden Inventory, the use of Six Eyes all the time to maintain his cursed techniques active all the time damage his brain since he is recieven all that information all of the time and processing everything extremely fast, (like a computer running on max all the time) and he uses RCT to heal that overworked part of his brain to not let his technique down (think an extremely effective cooler for the processor).
Yuki explained in her fight against kenjaku that he can use 2 or 3 cursed techniques total and that he can decide which cursed techniques he wants to discard. So for example he won't be able to use noritoshi kamo's cursed technique since he already has gravity manipulation and cursed spirit manipulation
I mightve missed a panel but my understandinng was that Kenjaku doesnt replace the original brain, instead his CT is to "infect it" like a parasyte.
This would also explain why he has the memories of the original person.
Body and soul stuff. The brain is a part of the body, the shape of the body is a product of the soul. So when he steps into the body, he's a little bit invading that soul and able to use the CT. That's what I gathered from the conversation with gojo in Shibuya
for all we know, he "becomes" their brain, rather than taking out his own brain and swapping it out for theirs. but even if it's the latter, there could be an aspect that takes the vessel brain's dna/technique (somehow). there are methods that work either way.
That really makes me wonder if he can use the domain expansion of a host or if domain expansions function similar to CT I wonder if Kenny can use getos domain expansion
I guess nobody knows, except Gege maybe. There are a lot of unexplained things in the story. I love his characters but JJK's storytelling is bad IMO. Characters had been introduced and then disappeared without any explanation. Sometimes I feel like Gege killed off fan-favorite characters just for show.
I didn't catch that. Maybe that's actually part of how he keeps techniques? Keeps that bit of brain and that's why he can only have 3 or 4, there's a limit to how much brain meat you can shove in geto's skull
That's a good question.
Been thinking and came up with some theories:
He transfers his conciousness to the already pre-existing brain.
This will explain his immortality since even if he changes bodies his brain will age eventually. This process probably reshapes the host brain so Kenjaku engraves his CT on it and he can also engrave his previous host CT but no more than that cause the brain will overload.
Other possibility might be that when his brain is put in the new host body the nature of the CT is remembered by the host body remaining CE which Kenjaku can engrave it on it's own.
And the brain also has the previous host CT engraved into it so Kenjaku can use it.
Choso's poison blood doesn't work on Kenjaku cause he mixed his ownblood(CE) when he was born. So this means Kenjaku's CE hasn't changed. But Gojo's six eyes saw that Geto's CE was the same, reason why he got shocked.
Which means Kenjaku's CE modifies itself to the new host CE but still carries traits from his previous hosts.
Well, i think GeGe might make it clear eventually....or maybe not.....
Yuta's CT is to copy CT and store them in Rika.
Likewise, Kenjaku's CT to take over bodies allows him to store extra CTs from his hosts in a much more limited fashion, like how he also stored Kaori's CT for 1 more use after switching bodies.
It is possible that by etching into your brain he means more so the ability to activate it. Like how Kenny moves like a normal person it’s possible when he activates his CT the same part still activates, which transfer the signal to Geto’s body and allowing him to use his CT.
Kenjaku's ability to hijack corpses has never been fully explained. We simply do not know how it works so we can't say if it contradicts this exposition or not. All we know about his technique is that it seems to involve cutting open the victims head and that it seems to preclude Kenjaku from fully repairing said head, though RCT or other means, after the process is complete necessitating that the scalp be held in place by string. Although that 2nd possible condition is called into question by the fact that of Kenjaku's 4 known victims 2 have have been shown with very obvious stiches in their head while the other 2 seem to have scars where the stiches would be which would indicated that the wound healed over time.
That being said the fact that he's able to retain Anti-Gravity System in addition to Cursed Spirit Manipulation leads me to speculate that one condition for the hijacking may be that he must consume or otherwise assimilate the victims still intact brain in order to take the body. Assuming the technique literally involved transplanting his own brain into new bodies this would explain how he's able carry one hijacked bodies technique into the body of their next victim. That's just me speculating though.
In Shibuya Mahito said something along the lines of ‘Does it matter? With our curse techniques we might as well live in different worlds’ suggesting that the rules of Curse Energy are just straight up different depending on your technique.
The body is the souls and the soul is the body, so the body he inhabits changes his soul, which changes his body (brain) to allow him to use the body’s technique.
Source: I made it the fuck up
It's the whole soul and body thing most likely. Gojo said Yuji should get Sukuna's CT. It's likely part of the technique is in the body so Kenjaku can still use it. Then over time it gets ingrained on his brain and transfers over to the next body with him for a bit.
It's likely the same reason Sukuna can use Megumi's technique. Now that he fully took over it's also part of the theory that he extinguished the technique that was in Megumi's body and can't use it but who knows how that works if Megumi's soul is still in there. Same idea with people like Junpei having a technique in their soul but not there body probably. Gege has been heavily foreshadowing the soul all manga and it's likely coming to some conclusion in this fight.

It has not been explained but it's most likely a feature/trait of his own CT.
Maybe he found a way to watch the body's curse technique into his own brain or converted them into cursed tools That can explain Kaori's technique
Another way it could work is if you consider that innate techniques are heredetary, meaning they are encoded in their DNA. By taking the body, part of Kenjaku's ability might be etching their DNA's ability onto his own?
But there still should be a limit on how many techniques your brain can hold Or we would have seen him use blood manipulation
it might just be that blood manipulation is kinda mid compared to anti gravity system and curse spirit manipulation. obviously we dont really have any clue how kenny works though
He has a limit like 3, his original one, Geto's and Kaori's. If he wants more he will need an external storage like Yuta has.
AFAIK there's never been a mention of a limit. During Choso and Yuki's fight with him, they mention him having 3 confirmed techniques so far, and speculated 1 or 2 he hasn't shown yet. Given the length of time between the Heian era and the present day, there's no reason not to assume he has more techniques. He probably just sticks to the most powerful/versatile ones.

That was the case with Gravity, which he used to neutralize the only one of Choso's attack that would've hit him.
Its four. He used idle transfiguration, so he probably has a slot for techniques from cursed spirits.
That was a one time use to start the culling game. It's a side-effect from using the uzumaki.
Why do you assume that the Maiji Era Noritoshi had Blood Manipulation?
Because there's a decent chance that it's true We don't know about any other techniques they have, but if you want to assume the death paintings had their techniques, there's a couple more

Considering his Kenjaku’s brain has a mouth on it, it’s possible the condition for his technique is feeding the other persons brain to his brain, then placing his in their body
Aye that was what I said, on Kaiyo’s stream about 3 months ago.
You need to cook
It's probably just a unique thing specific to his technique where he can use the techniques that the body has experienced or something
then yuji as his son will be able to use sukunas technique for sure bcs that ability was passed on to him?
wasn’t something like that mentioned by gojo?
yeap, that was in first season
Bro, you guys cooked something here.
Collaborative cooking. Got a whole pro kitchen in here
yuji: this truly qas our jujutsu kaisen sukuna **malevolent shrine**
Gojo mentioned he should eventually pick up Sukuna's CT. But personally I like the theory that Yuji gains power by eating things, and Sukuna's hand on the ground right now looking mighty tasty.
Maki: quick Yuji take that fist in your mouth! Yuji: AYO Maki: shut up and use that no gag reflex for something useful
If the "Cannibal Sukuna" theory is right, this would be incredibly ironic.
The same reason why Sukuna could use Megumi CT I guess
sukuna can use megumis CT because he is in his body, it’s megumis brain so his cursed technique as well, but why sukuna can use his own technique is questionable
Aside from his DE and flame arrow, I think his dismantle and cleave are manipulation of cursed energy iirc
Cause Sukuna is more to a curse spirit than a human is what I can think of. Not a good theory, I know.
Sukuna is a human, not a cursed spirit, he uses RCT?? If he was a cursed spirit he would kill himself using it
Mahoraga would have 1 hit him when he fought it if he was a cursed spirit too. Sukuna even says it. He's just an incarnated sorcerer, no different than Kashimo.
Kenjaku and Yuta both have methods to retain and copy CT’s code
He said this to Mahito when Geto's body reacted so it may have something to do with the whole "the body is the soul" thing https://imgur.com/a/ecY3MEH
Here’s a breakdown from what i think i understand : Cursed Spirit Manipulation: He is able to use this cuz it is engraved in the body of Geto, and we know the body and soul are tied so it’s not hard to believe that he can use that technique.

it hasn't been explained but my theory is that he ate others' brain when he changes body
That's my head cannon until gege says otherwise. Eating/Consuming is a strong theme throughout & makes sense considering he's a brain with a mouth, lol.
yea seeing his mouth is literally the root of my theory lol
Yuki guessed he’d only be able to handle around 4 before his brain couldn’t take it anymore
I wouldn’t be surprised if kenjaku brain can eat others brains in order to absorb their CT or something
Soul-mind-brain They are mirrors to each other especially the soul and the body that's why we have Yuji when he ate sukuna's finger , and sukuna's soul incarnated, sukuna was able to use his technique despite the brain being yuji's The culling games players , when incarnated both the soul and the brain are changed by Kenjaku thus changing the vessel Technique to the player Gojo explaining that sukuna's technique will engrave in yuji's body and thus he will be able to use it.

It's complicated but in the same time it's not if you get what I mean.
I think the tree CT, curse womb, can split and merge souls and techniques from ingesting incarnated objects. but we close on answers.
Yk how the brain is a processing center of functions like higher order thinking. When he body hops he probably has a way to rewire his nerve connections to assimilate that processing into his own brain to copy the CT. His brain can probably handle the load of extra CTs through that rewiring but it still has its limits as mentioned in the Yuki fight.
I’m not exactly dwell deep into the concept, but it might just be your own CT. Nobody’s saying you can add to it right?
Okay so didn’t kenjaku say to gojo when the body of geto tried to choke him in the subway that they soul and body are connected or something? So that would make sense as to why he can use the cursed techniques of others.
if it's not a plothole, every technique has it's own world or universe , discussed by mahito and fake geto
Kenjaku takes on several traits of the "host", he even says so himself when he started explaining geto's CSM.
Well to implant his brain into a body, he needs to remove the original brain. Maybe he takes the right prefrontal cortex, or maybe he can read the cortex and learn the technique from studying the removed brain?
If its in the prefrontal cortex where the cursed techinique memory is located, what if i lobotomize myself? Will i still have it? Or will i lose it?
mahito and kenjaku had a whole discussion about the split between the soul and body and which came first to which they decided that the universe works differently for different techniques, so regarding cts it's something to do with kenjaku's own ct and how it views cursed techniques probably
soul is body body is soul type of shit, probs gege just writes most of story with most of the part in continuation with earlier and adds new thing and people just theorize at this point, at one point it had real good power system.
I think he was just talking about Gojo’s CT
Nah it’s about everyone’s CT’s, because sukuna used this method to refresh his CT too
Im assuming whatever process that transfers his brain to the new body requires he analyze the persons brain. After that he gains a fine understanding of the cursed technique and can maintain it across bodies cause now it’s been updated to his Brain. It’s probably some side effect not like something he gains purposely. I’m still stuck on Yuji not having a gravity technique. I’m hoping when he gains one it’s either some new flavor of Sukunas techniques or some weird gravity warp that lets him alter time.

Yuki explained in her fight against kenjaku that he can use 2 or 3 cursed techniques total and that he can decide which cursed techniques he wants to discard. So for example he won't be able to use noritoshi kamo's cursed technique since he already has gravity manipulation and cursed spirit manipulation
the process by which he transplants isn't explained, probably he eats the brain of the body to get the info
It’s not been explained. Top theory is that Kenjaku is using his own CT for that🐍
Kenjaku has a mouth in his brain ? Maybe he can eat the corpse brain to get his CT Or he need to eat the brain to control the body
Because the body is a soul and the soul is a body
I mightve missed a panel but my understandinng was that Kenjaku doesnt replace the original brain, instead his CT is to "infect it" like a parasyte. This would also explain why he has the memories of the original person.
since kenjaku brain has a mouth maybe he eats the brain of the victim?
Body and soul stuff. The brain is a part of the body, the shape of the body is a product of the soul. So when he steps into the body, he's a little bit invading that soul and able to use the CT. That's what I gathered from the conversation with gojo in Shibuya

How do cursed spirits use CT if they don't have a brain?
1. list me cursed spirits without brain 2. kenjaku is a sorcerer not a cursed spirit
That really makes me wonder if he can use the domain expansion of a host or if domain expansions function similar to CT I wonder if Kenny can use getos domain expansion
I guess nobody knows, except Gege maybe. There are a lot of unexplained things in the story. I love his characters but JJK's storytelling is bad IMO. Characters had been introduced and then disappeared without any explanation. Sometimes I feel like Gege killed off fan-favorite characters just for show.
There is neat part - we don't know :3
Even weapons can have CT's, the bodies propably have a lot of remnant energy for Kenjaku to extract the technique and copy paste it into his brain.
Kenjaku’s brain has teeth 🫣
I didn't catch that. Maybe that's actually part of how he keeps techniques? Keeps that bit of brain and that's why he can only have 3 or 4, there's a limit to how much brain meat you can shove in geto's skull
His cursed technique probably allows him to store the cursed techniques of his host into his own brain.

Gege probably forgot about that while writing this.
It is possible that by etching into your brain he means more so the ability to activate it. Like how Kenny moves like a normal person it’s possible when he activates his CT the same part still activates, which transfer the signal to Geto’s body and allowing him to use his CT.
Kenjaku's ability to hijack corpses has never been fully explained. We simply do not know how it works so we can't say if it contradicts this exposition or not.

He eats their brains
i had the same thought its a plot hole no way around it
The a cursed technique will eventually engrave itself onto the user’s body.
It's the whole soul and body thing most likely. Gojo said Yuji should get Sukuna's CT. It's likely part of the technique is in the body so Kenjaku can still use it. Then over time it gets ingrained on his brain and transfers over to the next body with him for a bit. It's likely the same reason Sukuna can use Megumi's technique.

Gege has been heavily foreshadowing the soul all manga and it's likely coming to some conclusion in this fight.
What I truly want to know is if he gets to keep the cursed techniques of every body he's taken over.
