A high tier blood manipulation technique should be the ability to force a blood transfusion on an opponent and then kill them from the inside out

Realistically for Kamo to max blood manipulation out he would need to first gain RCT which is nearly impossible in the first place and then increase his RCT output and efficiency to heights comparable to that of Satoru Gojo or Ryomen Sukuna which is even more unlikely,That or he could self delete himself without using Jujutsu in hopes of coming back as a vengeful cursed spirit to enjoy the same benefits that Choso does this plan obviously has issues The weakness of blood loss is simply too great,Yes learning to reabsorb the blood could be a viable alternative but even that would have SERIOUS long term flaws for him he could catch a serious disease which would make it so he never reaches the heights of the technique,At the end of the day blood manipulation without a massive supply of blood is like the limitless without the six eyes or the ten shadows without the shadows it may have uses but those uses are very limited and have a low potential ceiling,The ‘bag’ option is also terrible One way this could be believably achieved is with a binding vow maybe he exchanges his ability to cast a domain one of his senses or something else for insane regenerative capabilities and RCT efficiency And speaking of serious diseases Kamo could get a sample of his blood and infect it with just the worst diseases you can think of and launch it at his opponents like a biological weapon ensuring that if he doesn’t win the fight he atleast made sure the rest of their life won’t be fun Another thing Kamo could do is gain a new understanding of his technique,Read,watch and look at everything that involves blood in the same way Mahito did with the soul,Figure out how blood can be used it’s properties,I think the second biggest weakness is users are told from birth they can only control THEIR blood if you instead teach them that all blood is on the menu then maybe they could control all blood that’s how techniques work in this series your own understanding of it impacts the technique If you could eliminate those two weaknesses a blood manipulation user would be genuinely unstoppable and truly deserving of being in the big 3 families not only would they have an endless supply of blood with RCT but they could also control yours maybe being able to pop you like a balloon

It would be cool if they could create shikigami from their blood and blow them up. Imagine a supernova but hundreds of small shikigami

For Attack: -As soon as you wound your opponent, mix your blood with theirs and make your blood oscillate and rotate while going through their blood stream, piercing their veins from the inside. Think of it as a each of your cells going forward and backwards really fast and they spin, while following your opponents blood stream. -When hitting the right side of your oppents body: just give your opponent a stroke. You can aim for a non-vital area like their leg, anything on the right goes to their head faster. -When on the left side: Thicken the blood inside them, making them lose their leg or blood supply to a kidney, -A stomach hit will cause both legs to go, and both kidneys, as the main artery from the heart comes from there, and a shoulder hit will cause arm loss. For Defense: -When damaged by opponent let your blood leak around the wound, harden it. When your opponent is close move that blood to them, rapidly. This should be possible while charging another attack, as your cursed technique is infused in the brain and the brain can have 3-4 techniques. Meaning you should be able to keep 3-4 attacks going at once with 1 technique. -If you can learn to passivly control blood manipulation then you can slowly leak blood through a small prick over weeks or months, growing armor on your skin. You should be able to move this to a teammate and if you get a Shikigami it could potentially protect that teammate with your technique while you attack. It's essentially a free blood-mech suit every couple months. For Speed: -Make your blood pump faster or produce more mitochondria, giving you more stamina. -Move yourself telekinetically with the blood. If Magneto can do it, so can you! This could give flight or just a small speed amp. -Make a wall of blood on the back of your body that pushes you forward. If you can do the full skin armor thing then just move yourself freely in 3 dimensions.

I think a full body exoskeleton suit made of blood should be a high tier blood manipulation technique

What if yujis blood manipulation is poisonous to rct. By getting your blood into your opponent you can disrupt it and unlike normal poisions it can fight against healing. Also maybe by circulating it thru an opponent you can predict thier movement and flow of cursed energy almost like precog. And maybe also create weak spots on an opponent like eight trigrams against charaka system in naruto.

I have actually been questioning why blood manipulation is prized and is thought to be on par with Limitless+6Es and 10ST, but this video actually gives me ideas on how it can actually be utilised with binding vows and shikigami so let me put in some ideas. I am thinking that Kamo would have a shikigami that can: Convert CE into blood for Kamo which is Kamo's able to manipulate. The shikigami is able to shoot long range attacks with this blood (Piercing blood, convergence, machine gun blood etc), machine gun, and is capable of fighting with user. Thanks to a commenter, the shikigami can be a combination of a bat and a mosquito. This guy alone without using the IT, he is able to fly and is very agile, use sonar to detect other people, suck blood out of people and possibly convert is to Kamo's CE. For Stack, the 8 Gates idea is awesome. I am thinking that it would be 3 levels. First Level has been shown with Choso during his fight with Yuji. Kamo is able to make warm heat from himself so nothing to different other than his strength. 2nd Level is base Yuta during fight with Yuji in Shibuya. He know exudes more intense heat that is painful to be near by. Level 3 is physical capabilities on par with Satoru Gojo. This makes his heat on par with Jogo but not on his level. A binding vow for this is that for each level, the length you use this technique, you will experience physical pain for that time being. For example level 3 has a level 10 pain can go on for a week while level 1 pain can be a level 2 pain that can go on for a day. So yea. thats my take lol

I saw a reddit that said the true potential of blood manipulation is share his abilities to others similar to the death womb painting but the condition being that the ability can be shared with only close relatives. This may explain their focus on family ties. Plus i saw the meaning of his name in the fandom, kamo translates to increase or add growth. This could result in a clan of grade one sorcerers who are amped by flowing red scales plus with their innate CT similar to the death womb paintings

I've always thought that BM could be very op (mainly cuz I'm a sucker of ATLA and how op bloodbending is in that show). So here's my take on it (+ ideas in the comments that I saw) : 1- So obviously there's the general stuff that the user can do like training, landing a black flash, learning RCT (gonna go deeper and that later), studying it's limits ect ect... 2- Then here's the specific stuff. First is having a shikigami, I'm not sure how they work but if you can give it the ability to make blood out of CE it'd be really strong but you could have it automatically make convergence to be able to use supernova or PB quicker, there's a lot you can do. 3- Binding vows are the quickest way to power yourself up and given how versatile BM is there's a lot of Binding vows you can make. For example make one that force you to use convergence ONLY for piercing blood making it stronger, or a very extreme version of the nanami one where can use your CT only for 2h a day. Imagine how strong you'd be condensing 22h of CT usage into 2h and using flowing red scale (there's some numbers I'd like to put here but I need some research). Or making you use just a tiny amount of blood but having it really powerful. There's a lot you can do 4- Blood manipulation has many many uses, you could put you blood in the enemy brain through the nose, lay traps using supernova, combine crimson binding with piercing blood to simulate a sure hit effect without a domain (Kashimo !?), or like one guy said manipulate the electric charge of the blood to shock opponent on contact (Kashimo !?). There's infinite ways to use BM so the more creative you are the better. 5- RCT is op in itself but giving limitless blood is really op. But how does Gojo use red or Kenjaku the gravity technique ? Cursed technique reversal, and since BM allows you to manipulate your blood, was if cursed technique reversal lets you manipulate the blood of others, that would make BM very op. For example you could bypass limitless just by manipulating Gojo's blood. Oh no ! Sukuna's using malevolent shrine ! Wait he's dead of brain damage. obviously you could counter using you ce but it would still be extremely strong. 6- just a simple domain idea, a domain where all the blood is drawn to the center of the domain, simple but very lethal

Get some cursed hybrid of Gojo and Kamo: blood manipulation + 6 eyes = full body blood control, every single blood vessel.

one ability possible for blood manipulation is manipulation of bio-electricity to build up a charge and electrocute a enemy we haven't seen it in the manga but its more than possible since we have seen thermal manipulation of blood in flowing scale whitch means more abstract manipulation of blood is possible compared to a water bending style of blood manipulation.

if choso risks thrombosis with blood hardening making yourself burning hot would definitely just kill you lmao

I like talking about all the applications of abilities so with the Shikigami idea I came up with 2 ideas for blood manipulation Shikigami that could help with its main weakness 1. A mosquito Shikigami that could perform blood transfusion, giving the user their targets blood to refill their own reserves or transfer their own blood to the opponent so they could control them. 2. A parasite Shikigami that is constantly sucking small amounts of blood from the user and storing it inside its body. This allows for them to have extra blood whenever they need by having the parasite pump it back into their body.

The shikigami should be a... MOSQUITO!!! Oh, or maybe a BAT! A BAT-QUITO! Wait. Perhaps a LEECH! A BALEETO! Let me stop 😅

I think if a blood manipulation user put a powerful binding vow on themselves. Like they can only use cursed energy for 30 minutes or an hour a day. Then they could gain a powerful regeneration factor that would allow them to regenerate most of the blood they use or all.

New application of blood manipulation would be combining slicing exorcism and crimson binding to create a cage of slicing exocism which will cut the opponent and keeps on contracting to a smaller cage slowy

Imagine having an inventory curse filled with years of blood stored up mechamaru style

Blood munipulation is prized for its versatility if you think about it it has the potential to work like yoruzu technique

Blood manipulation allows the user to control their own blood. So, the curse technique reversal could perhaps allow them to control water com outside sources (like a water bender). In JJK, blood manipulation has been used to emphasize family relationships, having them being able to control water would be a play on the “blood being thicker than water” motif. By combining the normal application of blood manipulation and this theoretical water manipulation, the user could control another person’s body (blood and water).
