Give Yuji's cursed gauntlets an actual ability or interpretation

Yuji pulled up to Shinjuku with these cool monster looking arms that made his design look so cool and it turned out they were just useless gauntlets that hide his severed finger. That was really lame so im wondering what Gege couldve one

I'll go first. I think the gauntlets coudlve absorbed blood from opponents to strengthen its physical ability and also release to perform supernova from the fist maybe

Simple Cursed Technique - Power of Friendship

Cursed Technique: Power of Friendship

  • The user becomes stronger through their bonds with other people. The more friends and allies they have, the stronger they get.
  • The closer the bond, the bigger the boost to their cursed energy and power.
  • Fighting alongside friends lets the user and the friends push past their normal limits.
  • Broken bonds or betrayal weaken the technique

Friendship triumphs all!! Yay!!

Any cursed technique that deals with an application of physics is immediately special grade

Earlier there was a post about a hypothetical technique called “STOP” (https://www.reddit.com/r/CTsandbox/s/ktWg4FdS9z credit to this guy, great post!) that was really simple, it reduced the targets relative momentum to zero. The second I read that my physics nerd brain went haywire, especially with how much cursed techniques are up to interpretation in JJK, because you can immediately do some crazy stuff depending on how precise you can get with the technique.

It made me realize that’s why Yuki and Gojo are ranked special grade. Even though the explanation of infinity sounds hella complicated, Limitless is actually pretty simple: the user has control over space (not like Uro obviously), Yuki has control over mass, and any other physics concepts would immediately be ranked special grade because these concepts pushed to their limit end up in the realm of theory. Anything could happen depending on how the sorcerer views their own technique so they are immediately a threat to the world

Curse of the Nuclear Catastrophe: Shōenbaku

I had already presented Shōenbaku in a post on my old account, but that was a pencil and paper drawing; here I decided to do it digitally and with colors. (Could this be considered a repost?

SHŌENBAKU

Being a Curse of Immediate Catastrophe, Shōenbaku was born from all the bad feelings caused by the Little Boy bomb dropped on Hiroshima in 1945, but ended up also feeding on the feelings from the Fat Man bomb dropped on Nagasaki and later on the fear of a third atomic bomb being dropped on Tokyo.

Like all Immediate Catastrophe Curses, Shōenbaku was born as a cursed womb, a fetus similar to that of a human, floating in the middle of the destroyed Hiroshima. The quantity and density of its energy were so high that Non-Sorcerers were able to see it without the aid of any Cursed Tool.

Maturation

Like a cursed womb, Shōenbaku matures into a complete form, assuming a highly distorted human shape with reptilian features, and its gigantic scale is unusual for a curse. Standing 80 meters tall, this being is a colossus, like other curses of Immediate Catastrophe.

However, the evolution doesn't stop there. Shōenbaku begins to accumulate more and more energy over time, to the point of brutally self-destructing from the inside. Its physical appearance changes to a burnt and deteriorated form that continues to accumulate energy, eventually combusting internally and escaping through its chest, leaving behind a gigantic cloud of smoke.

When it reaches a critical point, the curse completely self-destructs in an atomic explosion, releasing its radiated energy in all directions.

But Shōenbaku can delay his death by releasing his energy in brutal bursts, but this only delays his inevitable end.

Energy Trace: Irradiated

The cursed energy of this curse possesses special properties that mimic the longevity of radiation effects. This energy is almost impossible to cleanse from the places it permeates, leaving entire areas with enough energy residue to make a non-sorcerer see and feel curses permanently.

Since Shōenbaku releases immense amounts of this energy in its raw form every second of its existence, this released energy can create minor curses that are born from the mixture of its energy and its remnants that burn in the smoke.

Torrent Sorcery

“I've done the math. When you pull this trigger, one plus one equals zero. Every time.”

The Innate Technique of “????? ?????”. Granting them the ability to create momentary glitches in themselves, much like glitches or errors in videos, to create falsities their position, senses, features or properties, visualized by a visual distortion akin to video's low frame rate or glitching.

When activating Torrent Sorcery, it is visualized as the user's body distorting with digital bytes manifesting around the user as they activate the Technique. Parts of their body overlayed with the pixelated visual as the Technique manipulates and shapes their state and body. The Technique has no requirements for activation, and can be activated at any time, but is limited to only working on the user and cannot have its abilities passed onto other individuals.

The power of Torrent Sorcery lies in the falsities it can create through activation. The Technique offers the ability to create momentary falsities in the user, akin to editing a video recording on an older system, as if editing a live feed of themselves and altering themselves based upon the edits made. This grants the user a wide range of abilities. For example, much like videos of the era, the user will be able to transport themselves great distances instantaneously, similarly to the jump-cuts and freeze frames of videos of the time. Where the video would pause only for it to cut multiple seconds forward in time. They can distort their body to make it harder to track themselves, increasing their speed alongside the distortion.

The user can additionally cause visual changes in their physical features and properties, such as changing the placement and size of their facial features. Distorting themselves visually to match the appearance of another individual, in which the user will have a digital covering of the appearance in which they create. They can create visual clones of themselves that match the user visually which can be passed through, and even turn invisible by covering themselves in their Technique fully to match their background.

Technique Weaknesses:

- The major drawback of Torrent Sorcery lies in excessive usage. Every activation of the Technique in quick succession builds up Lag, in which the Technique gains the potential to delay activation or even pause in effect at random. The more excessively the user activates the Technique in any way, the more lag they produce, and thus the more likely the Technique is to be delayed upon activation, or even freeze the user in place due to the amount of lag they've built up.

- Visual distortions caused by Torrent Sorcery can be discerned and caught by momentary pauses in movement or expansions in places they shouldn't be. Such as if the user were to alter their face, their mouth or eyes may visualize strangely or may look in different directions for a moment, where an onlooker can catch the momentary distortion.

Influences: Video (InFamous Second Son), Itazura (Kagurabachi), Accelerated Decoys (Spider-Man: Edge of Time), Kamui (Naruto: Shippuden).

This is my first time posting here! I have about, like, 40 or so Cursed Technique's that I've written out in my spare time over the past few years since becoming a JJK fan, both for myself and my friends. This one is a more recent one, so I hope you enjoy!

Cursed technique: japa mala

Japa Mala: This technique allows its user to freely create and manipulate one or more juzu, Buddhist bead necklaces.

The user can manipulate both the length and size of the juzu and control them at will. Aoshi typically uses this technique in combination with his martial arts prowess, closing the distance with his enemies and launching a juzu at point-blank range, like a shotgun blast scattering multiple pellets.

By increasing the size of the juzu, he can also make his beads orbit around him as a means of defense or support.

Domain Expansion: 108 Sins.

This Domain Expansion appears as a kind of altar, surrounded by four giant Buddha statues. Each statue holds a juzu in its hand.

The guaranteed strike of the Domain causes the juzu of the four statues to reach and grab the target. Subsequently, the statues begin to slowly pull on their juzu until the target's body is dismembered.

•Can’t be too much stronger than Gojo (you can be a little bit or on par, but preferably as weak as possibly to still win!)
•Could be one technique to beat all or multiple, doesn’t matter.
•The technique can have reversal, domains, max output, whatever.
•You can NOT have one shot moves, you can’t have techniques that kill shikigami instantly nor can you use RCT against the curses.
•Domains that guarantee kills are banned too (infinite void, malevolent shrine, etc.)
•Has to be original! I know technically you could just say ‘Shrine’ or ‘Limitless plus Six Eyes’ but be creative!
•NO CURSED TOOLS

Cursed Technique: Heighway Dragon Skin

"The nature of a surface governs the nature of its interactions..."


Description:

Cursed energy reinforcement is a fundamental application of jujutsu sorcerery that strengthens the body by compressing cursed energy into dense, stable layers around the user’s flesh. The smoother and more uniform the reinforcement, the more effectively force is absorbed and distributed.

Instead of compressing cursed energy into smooth reinforcement, this technique allows the user to recursively arrange their cursed energy using the fractalised geometry of the Heighway Dragon Curve.

The resulting reinforcement is not smoothly layered but contained within infinitely folding jagged boundaries. By focusing, the user is able to alter fractal iteration of their reinforcement to adjust it's contact dynamics - changing how it interacts with force, friction, sound, and momentum in specialized ways.


Mechanics:

This technique stabilises cursed energy into reinforcement by recursively folding it rather than compressing it. As a result, the edges of this reinforcement are jagged and uneven rather than smooth.

By focusing the user can alter the iteration depth of their reinforcement, this changes the emerging detail at the edge of their reinforcement and adjusts the specific contact dynamics of their cursed energy in a variety of ways - these altered surfaces are called Scales.

Each Scale modifies how cursed energy interacts by emulating naturally evolved edge structures found in biological systems.


Limitations:

Rapidly cycling through different Scales requires extreme mental focus and cursed energy control, overextension can cause vertigo, extreme confusion, and even result in technique burnout - this drawback is mitigated the more skilled the user of this technique is

Each Scale specialises the users reinforcement in specific ways, skilled opponents can learn the effect of Scales and sense changes to the users reinforcement allowing them to predict the users actions or exploit transitions between Scales


Base Technique: Fractal Reinforcement

Instead of reinforcing through densely compressed cursed energy, the user overlays their body with recursively folded cursed energy to create a reinforcement states called Scales.

Each Scale represents a distinct recursion of the same fractal, the different "zoom-levels" leading to different structures or microstructures at the edges of the users reinforcement which changes it's interaction mechanics.

Solid Scale

"An edge folded inward disperses force before impact settles..."

The structured edge of the users reinforcement becomes densely folded, emulating the overlapping scale structures found in tempered metals.

Incoming force is redirected along geometric subdivisions and dispersed through repeated inward folds. This Scale grants the user extreme defensive reinforcement and durability.

Savage Scale

"Refusing smooth contact turns pressure into tearing..."

Like the jagged protrusions of teeth from a jaw or serrations along predatory fangs themselves, this Scale alters the users fractal reinforcement and arranges protrusions outward instead of inward.

The users reinforcement is oriented towards offense as in this state it catches, grinds, and tears matter and opposing cursed energy. This Scale massively increases the users offensive capabilities and striking power, while minimising the defensive gain from their reinforcement.

Slipstream Scale

"The edge that guides flow removes resistance before it forms..."

By refining the ragged edges of their reinforcement further, the users cursed energy begins to enulate the drag reducing micro-structure of sharks skin. The users reinforcement forms aligned, repeated grooves which smooths air and energy flow around their body and reduces momentum transfer and turbulence.

Instead of maximising defence, this Scale enhances the users speed, acceleration, and movement fluidity. They are capable of explosive movements and rapid changes in direction with almost no loss of speed.

Silent Scale

"An edge that breaks turbulence silences its own passage..."

The edge of the users reinforcement softens slightly into a fringe like structure which mirrors the edge dynamics of owl feathers which dampen noise by minimising energy propagation.

This Scale diffuses the edge of the users cursed energy into almost imperceptible micro-disturbances. This dramatically increases the users stealth, as signs of their movements and cursed energy signature are so suppressed they become near completely imperceptible.

Setae Scale

"When an edge has enough contact it can cling to anything..."

The edge of the users cursed energy branches into vast quantities of tiny, interacting surfaces in a manner similar to the setae of gecko skin which allows them to adhere to any surface.

Rather than enhancing durability, power, or movement, this Scale increases the surface area of contact with the users reinforcement so much it becomes adhesive. This massively increases the users traction and leverage giving them impossible balance control and the ability to stick to walls and unstable surfaces.


CT Amplification: Dragon Scale

"The perfect life form has the perfect scales..."  

The user increases the fractal boundary of their cursed energy increasing the perimeter length of their reinforcement without affecting its density. This creates a spatial distortion in the users cursed energy which allows it to contain far greater volume than its structure should permit briefly creating impossible internal reserves and circulation efficiency.

While this state is maintained, the user is able to benefit from all other Scale types simultaneously, and can further enhance the effect of specific Scales simultaneously across different body regions. The user can fluidly alter the interaction dynamics of their cursed energy mid-impact or can layer several Scale behaviours into single actions.


Reverse Cursed Technique: Shed Scale

Instead of increasing the edge complexity of their own cursed energy, the reversal of this technique allows the user to collapse the edge complexity of opposing cursed energy.

This allows the user to collapse and cancel enemies reinforcement or barriers. Simple effects such as reinforcement are immediately negated on contact. Barriers which contain complex effects or rules take longer to simplify to the point which leads to their negation.

Extremely complicated barrier effects (such as the Culling Games Barriers) may require such sustained exposure to this reversal that the user cannot maintain it due to the limitstion of their reserves, making such barriers effectively impenetrable to this reversal.


Maximum Technique: Ouroboros Coil

The user continually folds and refolds their cursed energy in on itself creating a whirling, dragon-shaped construct of fractalized cursed energy. This creates a growing field of cursed energy surrounding the user like a maelstrom that functions similarly to domain amplification.

Opponents techniques or cursed energy entering this field rapidly destabilise while any physical matter (not including the users body) within the affected area is repeatedly fractured along geometric vectors and shredded by infinitely propagating edges.


Domain Expansion: Stomach of the Sleeping Dragon

"There's no escape from the belly of the beast..."

Domain Environment:

A highly complex, geometric domain. The interior resembles endlessly folding and shifting surfaces of lacquered, reflective black.

The domain itself appears to be finite at first, resembling cracked mirrors or irregular scales however on entrance to the domain the landscape shifts into itself like origami revealing smaller and smaller versions of itself and repeating endlessly.

As the unstable shapes of the domain shift a constant, low grinding can be heard. Initially it sounds like stone plates shearing across each other, but as the sound persists it begins to resemble the distant growling of some impossibly large beast.

Domain Effect:

The surface interactions of all cursed energy within the domain is commanded by the user of this technique. They are able to immediately and fluidly alter their own cursed energy boundary to maximise its efficacy for offense, defence, and movement

Simultaneously the user can interfere with their opponents cursed energy to maximise the impact of attacks against them or adjust friction to inhibit their movement.

Cursed Technique: Dustpan Paradox

(Inspired by how I always leave a tiny bit of dirt behind whenever I use one of these stupid things)

This cursed technique gives the user the ability to begin to negate damage the closer they get to death.
Similar to the Infinity technique Gojo uses, this technique will start off taking normal damage, but the closer the user gets to dying, the less they take, similar to missing some bits of dirt when sweep up with a dustpan.

The technique does not fully stop damage, instead it just lowers it. Strong enough attacks, or even just attacking a bunch, will kill the user.

‘Blessed’ Technique: Reversed Reserve

This cursed technique involves using strikes of Reversed Cursed Energy to attack directly at the Cursed Energy reserves of an opponent, which can remove a large majority, if not all of the opponents CE in one strike if they don’t block themselves with RCE before it lands.
This technique has the adverse affect of healing the enemy while destroying their reserves, but the downtime that having Cursed Energy removed or lowered tends to make up for it.
It can be learned by almost any sorcerer, so long as they are capable of using RCT and inflicting it beyond just their body.

Abiogenesis

Thinking bout a technique about the concept of abiogenesis, with the user being able to force inanimate objects into organic ones (while mantaining most of their form, being basically a shikigami) for a few seconds. Need some ideas here, whats the maximum potential of this? A domain? (Not restricted to that previous base, its just the initial idea i had)

How would you significantly upgrade a CT using binding vows creatively

I would create a binding vow for CSM, where after extracting a CT from a Cursed Spirit during Maximum Uzumaki, instead of having it be a one time use, the user can use that CT freely whenever for as long as they want, but they cannot then summon curse spirits that are of the same grade and above as the Cursed Spirit they extracted the technique from. An example would be Kenjaku freely being able to use idle Transfiguration for however long he likes, but then cannot summon other Special Grade Curses while he keeps the technique extracted, and can only use them again once he relinquishes the technique. A pro of this binding vow would be that the user can still summon lower grade Cursed Spirits. This also applies to if the Technique extracted is from a Grade 1 spirit, but then the user cannot summon a G1 spirit as well as Special Grade Spirits.

Ryu stomps Hakari⬇️

Hakari literally has nothing over Ryu, even removing Ryu's Domain he'd still run over Hakari any day of the week

•Hakari Is a punch and kick merchant, and I'm sure Ryu could box Hakari for 4 minutes and 11 seconds (he literally sent Rika Flying with a punch)

•Ryu has also has way Better Durability

  1. Ryu tanked a dismantle from 16F Sukuna

  2. Hakari got his waist pierced by Charles

•Hakari doesn't even have RCT outside of his Domain

•What's he gonna do while Ryu charges a full Power Granite Blast? Throw some train doors at him?
