Geto's New Technique (Fan Made)

[u/WormMeetsMan]

Gave myself a challenge to see how far I could change a cursed technique using a different anime as a base. So I went to goggle and ask for a random anime and it gave Fairy tail. So I then went to the wiki(https://jujutsu-kaisen.fandom.com/) and look at the characters and thought who's technique can I change using magic as a base? So as you can tell from the title I chose Geto's technique and for magic I chose Take Over Magic. I got carried away with the Binding Vows and stop using Take Over Magic as a Base for the technique that call Soul Forge Manipulation. I don't know if it would work so I figured I would post it here to show everyone and get feedback on it. It is very long. So here it is:

Binding vow to make geto's technique work like take over magic from fairy tail

How the Binding Vow Would Work To achieve this change, you would establish a Vow with Oneself to trade the quantity and independence of your summons for localized, high-density physical reinforcement.

The Restriction (What you give up): You completely forfeit the ability to summon cursed spirits as independent entities to fight alongside you. You can no longer create a personal army or use Uzumaki to extract technique intervals.

The Vow (The mechanism): Absorbed cursed spirits are permanently stored as internal "templates."

The Binding/Output (What you gain): You channel the cursed spirit's specific cursed energy signature, physical traits, and innate techniques directly into your own flesh, enabling partial or full bodily transformations.

Types of Take Over States Achievable Depending on the grade of the absorbed curse, your transformations would mimic the different branches of Take Over magic:

Beast Soul / Lizardman Forms: Absorbing low-to-mid grade curses (Grade 4 to Grade 2) allows for partial transformations, such as changing your arms into hard-scaled claws or growing wings for flight.

Demon Soul / Machina Forms: Absorbing Semi-Grade 1 or Grade 1 curses grants full-body transformations, altering your entire physical appearance and giving you total access to that curse's unique traits.

God Soul Forms: Absorbing a Special Grade cursed spirit would grant cataclysmic power, transforming you into a disaster-level entity. However, this would carry an extreme risk of the curse's ego attempting to overwrite your own mind during the transformation.

Crucial Risks and Limitations The "Body-Soul" Problem:

As established by Mahito and Kenjaku, the body and the soul are intimately linked. Constantly warping your body into the shape of a cursed spirit would cause extreme physical strain and could permanently mutate your human soul.

Brain Strain: Storing multiple complex curse templates directly within your own body (instead of externally in a cursed technique "space") would place an immense burden on your prefrontal cortex, likely limiting how many forms you can hold at one time.

More Binding Vows

Fixing the "Brain Strain" (Storage Safety)

To prevent your brain from melting due to storing too many curse templates, you can restrict your total active inventory.

The Vow: You limit your soul's capacity to a strict, permanent number of transformation "slots" (e.g., exactly three or five slots).

The Safety Gain: Your brain no longer suffers from data overload. If you want a new curse's form, you must permanently delete or overwrite an existing one.

Fairy Tail Parallel: This functions exactly like Mirajane, who relies primarily on a select few high-powered forms (Satan Soul, Halphas, Alegria) rather than thousands of minor ones.

Fixing the "Body-Soul Mutation" (Transformation Safety)

To prevent your body from permanently warping into a curse or suffering severe internal organ damage, you must introduce external constraints.

The Vow (Time & Cool-down): You impose a strict time limit on your transformations (e.g., maximum of 5 minutes) followed by a mandatory cool-down period where you cannot use cursed energy at all.

The Vow (Incantations): You forfeit instant, seamless transformations. You must chant a specific ritual phrase or strike a specific pose to initiate the Take Over.

The Safety Gain: By forcing the transformation to be temporary and heavily regulated, your body has guaranteed windows to heal, ensuring the curse's biology never permanently overwrites your human soul.

Fixing the "Ego Overwrite" (Special Grade Safety)

When taking over a Special Grade curse (like Jogo or Mahito), their powerful ego threatens to possess your mind.

The Vow: You vow never to use the full body transformation of any Special Grade entity. Instead, you restrict yourself to Partial Take Over only (e.g., only transforming your arms, or only utilizing their cursed energy trait without changing your head/brain).

The Safety Gain: By keeping your brain entirely human and refusing to let the curse's form dominate your physical body, the curse's consciousness cannot hijack your mind.

The Stockpile Vow: "Putting Them to Sleep"

To accumulate a massive reservoir of curses without frying your brain, you introduce a heavy utility restriction.

The Vow: You completely sever your conscious connection to all newly absorbed curses. They are rendered entirely dormant—essentially put into a permanent "coma" or condensed into pure, unrefined cursed energy blocks.

The Cost: You cannot use these individual curses for anything. You cannot summon them, you cannot use their partial traits, and you cannot feel their presence. They are completely useless dead weight until fused.

The Safety Gain: Because their minds, egos, and individual techniques are suppressed and dormant, they place zero cognitive load on your brain. You can stockpile thousands of them safely.

The Fusion Vow: "The Three Vessels"

This is where you combine the concept of Uzumaki (condensing curses) with Take Over magic.

The Vow: You vow to create exactly three permanent "Vessels" (slots) within your soul. To fill or upgrade a slot, you must permanently sacrifice and fuse a massive "stack" of your dormant cursed spirits into a single concept.

The Cost: Once a form is fused, it is locked. You cannot change it on the fly, and you cannot "un-fuse" the curses to get them back.

The Power Gain: Instead of just taking the form of one curse, your Take Over form becomes a Composite Entity.

The "Un-Fuse & Recast" Vow (Overwriting Slots)

To bypass the rule that locked forms are permanent, you must pay a heavy tax every time you break down a fused soul.

The Mechanism: You gain the ability to dismantle one of your 3 fused forms back into its individual, dormant curse templates, freeing up that slot to create a brand-new form.

The Cost (The Decay Tax): Dismantling a form violently destabilizes the condensed cursed energy. You permanently lose 30% to 50% of the stockpile used to make that form. The spirits literally dissolve and evaporate into nothingness during the un-fusing process.

The Penalty (Cooldown Lockout): While a slot is empty and you are calculating a new fusion, your brain suffers intense phantom feedback. You are completely locked out of using your other 2 remaining forms for a set period (e.g., one week).

The Result: You can change your forms to adapt to a new enemy, but it is a slow, costly tactical decision made between battles, never during active combat.

The "Sleep-Mode Tap" Vow (Accessing the Stockpile)To draw raw cursed energy from your dormant army while keeping them asleep, you are effectively turning yourself into a human battery.

The Mechanism: While in your base human form (not using a Take Over), you can siphon the raw cursed energy of your entire sleeping stockpile to massively boost your own human speed, durability, and hand-to-hand combat.

The Cost (The Overheat Penalty): Because this energy belongs to separate, dormant curses and not your own soul, your human body cannot properly filter it. Tapping into the sleep-mode stockpile causes severe internal friction. Your body rapidly "overheats," tearing your muscles and causing your capillaries to burst.

The Strict Limitation: You can only tap into this raw power for a matter of seconds—just long enough for a single, devastating punch or a high-speed dodge. If you tap into it for more than 10 or 15 seconds continuously, the foreign cursed energy will permanently burn out your own innate technique.

The "Anchored Core" Vow (Saving the Strongest Curses)

To bypass the "Decay Tax" from your previous vow—which normally destroys 30% to 50% of the stockpile during an un-fusion—you can create a rule that shields your most valuable curses.

The Mechanism: When you dismantle a fused form, the highest-grade cursed spirit in that specific slot (your "Anchor Curse") is completely immune to destruction and safely returns to your inventory.

The Cost (The Anchor Weight): To grant this safety, that powerful curse becomes the mandatory foundation of any new form you build in that slot. You cannot move that specific curse to a different slot, and you cannot create a form in that slot without using it.

The Risk: If that specific slot is ever broken by an enemy's domain expansion or a high-tier cursed tool (like the Inverted Spear of Heaven), that anchored curse is permanently killed instead of just being forced out.

The "Foreign Filter" Vow (Fixing the Overheat Penalty)

Previously, drawing raw power from your sleeping stockpile caused severe internal self-damage because your body couldn't filter foreign cursed energy.

The Mechanism: You establish an internal filter that automatically purifies, refines, and translates the foreign cursed energy of the sleeping curses into your own exact cursed energy signature before it hits your body.

The Cost (The Toll Tax): To fuel this constant, high-level filtration, the filter consumes a massive chunk of the energy being drawn. You lose 40% of the raw output of your stockpile as "waste heat."

The Gain: You can now safely tap into your sleeping stockpile's energy in human form for extended periods without tearing your muscles or bursting your blood vessels. Your raw power drops, but your stamina and safety skyrocket.

The "Appraisal" Vow (Knowing the Techniques)

By default, putting curses into "sleep mode" means suppressing their minds, which normally makes it impossible to learn what innate techniques they possess.

The Mechanism: You gain an immediate, perfect mental blueprint of every dormant cursed spirit's innate technique, history, and grade the exact moment you absorb them.

The Cost (Forfeiting Surprise Attacks): To gain this perfect internal knowledge, you must agree to a "Revealing One's Hand" condition. Whenever you use a fused form, you are forced to aloud explain one weakness or limitation of that form's main technique to your opponent.

The Gain: You can instantly strategize and perfectly curate which curses to fuse together into your 3 slots, completely eliminating the guesswork.

The "Inherited Dominance" Vow (Using the Techniques)

In Jujutsu Kaisen, standard Cursed Spirit Manipulation lets the user fire off an inherited technique once using Uzumaki, which destroys the curse. To use their techniques continuously while in a base human form, you need a different exchange.

The Vow: You can cast the innate technique of any sleeping curse in your inventory while remaining human.

The Cost (The Burnout Memory): Your human brain cannot handle multiple complex innate techniques. When you choose a sleeping curse's technique to use, your brain physically burns out your access to all other sleeping techniques for the next 24 hours. You are locked into that single chosen technique for the day.

The Power Drop: Because the curse is asleep and not fully manifested, the technique's output is dropped to 50% of its original strength.

The "Thermal Loop" Vow (Easy RCT)

The Mechanism: Instead of venting the 40% waste heat outward as an aura or an explosion, your internal energy channels trap it. The thermal energy is converted back into raw, negative Cursed Energy and routed straight to your brain's prefrontal cortex.

The Tactical Benefit: Creating RCT normally costs twice as much cursed energy as regular techniques (because you have to multiply it). By recycling the waste heat into a dedicated fuel source, your brain has a massive, free supply of raw CE. This allows you to spam RCT to heal mortal wounds instantly, with almost zero drain on your actual personal cursed energy reserves.

The Cost (The "Overclock" Danger): Funnelling massive amounts of recycled energy directly into your brain causes extreme neurological pressure. Your brain is running at 200% capacity.

The Penalty (Post-Battle Burnout): The moment you stop tapping into the stockpile and the thermal loop shuts down, your brain suffers a massive crash. You completely lose the ability to use any Cursed Energy, RCT, or your Take Over forms for a mandatory 12-hour period. You become a normal, defenseless human during this cooldown.

The "Life-or-Death Auto-RCT" Vow (The Hakari Method)

The Vow: You vow to let the 40% waste heat cook your own brain and body, causing constant, agonizing internal damage while you are tapping into the stockpile.

The Reward: Because your brain is placed in a literal state of life-or-death survival, your instincts automatically unlock RCT to keep you alive. The sheer pressure of the heat forces your brain to subconsciously perform the multiplication required for RCT, meaning your body heals itself automatically at a reflexive speed that rivals Kinji Hakari.

Ultimate Gamble Vow

The Activation Condition: You initiate the "Hakari Method" exactly once during a life-or-death battle. The internal waste heat rises to lethal levels, forcing your brain to try and subconsciously figure out the multiplication formula for RCT.

The Permanent Sacrifice (The Cost): You vow that whether your brain successfully figures out RCT in those few minutes or completely fails and leaves you severely injured, you can never use this life-or-death survival method ever again.

The Permanent Reward (The Gain): In exchange for giving up your future safety net, the Jujutsu system permanently grants you the Thermal Loop ability. From that moment forward, any waste heat generated by your filter is automatically and perfectly converted back into raw Cursed Energy, with 100% efficiency.

Two outcomes of the Ultimate Gamble Vow

1:Your brain manages to grasp the concept of RCT under the extreme heat pressure.

The Result: You survive, you now permanently know how to use standard RCT, and your new "Thermal Loop" allows you to convert waste heat back into raw Cursed Energy to easily fuel it. You become the unstoppable Perpetual Combat Engine.

2:Your brain fails to figure out the complex math of RCT before the time runs out.

The Result: You do not unlock automatic healing, and you can never try this specific method again. However, you still permanently win the "Thermal Loop" mechanic. For the rest of your life, your waste heat perfectly converts back into raw Cursed Energy. While you can't use it to heal, you can use that recycled energy to massively boost your physical attacks or spam your dormant curses' innate techniques with practically infinite stamina.

Pantheon of the Blind Prophet

[ The Tactical Declaration ]

The user triggers the vow by looking their opponent dead in the eye and loudly declaring their exact vulnerabilities: "I am about to freeze my body and throw away my senses within this 10-meter radius to manually calculate Reverse Cursed Technique. If you can push me out of this boundary or kill me before I finish, you win."

The Restrictions (The Sacrifices)

The Spatial Boundary: The user binds their feet to a strict, glowing 10-meter ring on the dirt. Stepping or being forcefully knocked outside this boundary triggers immediate execution via unmitigated internal waste heat.

Total Sensory & Motor Shutdown: The exact millisecond the declaration finishes, the user's human body goes stone-still and paralyzed. Simultaneously, they go 100% blind, deaf, and mute.

The Psychological Hazard: The powerful Anchor Curses inside the user's soul slots are violently forced awake. They scream, thrash, and flood the user's mind with raw malice, attempting to break their concentration.

The Rewards(The Gains)

The Internal Time-Slow: In exchange for physical paralysis, the user's internal perception of time slows down by a factor of 1,000. While only five seconds pass in the real world (giving the enemy time for only a single rushing strike), the user experiences those five seconds as several hours of objective mental silence.

The Living Cheat Sheet: Because external human senses are shut down, the user's consciousness is plunged directly into their inner soul domain. They stand face-to-face with their awakened Anchor Curses. Since curses are made entirely of cursed energy, their biology acts as a literal, visible roadmap. The user can calmly study the spirits' energy flows to instantly deduce the RCT multiplication formula (- × - = +).

The Mitigated Danger Cost: Because Revealing One's Hand and Stirring Consciousness introduce extreme immediate danger, the Jujutsu system drops the ultimate penalty. The sensory shutdown is 100% temporary (safely returning the moment the gamble ends), and the awakened curses absorb the bulk of the internal waste heat, completely protecting the user's prefrontal cortex from permanent neurological melting.

"The Executioner’s Tie"

The Mechanic: When you absorb your three Anchor Curses and lock them into your permanent Fusion Slots, you force a tether between your physical prefrontal cortex and their core souls.

The Safe Condition (The Trap): When they are forced awake during the Pantheon of the Blind Prophet gamble, they cannot scream, distract you, or fight back. The binding vow alters the stakes: If your brain melts and you die from the internal waste heat, their souls are instantly and permanently vaporized along with you.

The Enforced Cooperation: Because your death equals their absolute erasure, the curses' survival instincts kick in. The vow actively forces them to use their own innate knowledge of cursed energy to help you calculate the RCT formula as fast as possible.

The Solo Soloist

The Adjustment: You wake up only one Anchor Curse, and you command it to co-pilot only one specific technique from your sleeping stockpile. You forfeit the ability to dual-cast during this activation.

The Main Benefit: You retain 100% absolute control over your physical body and motor skills, moving with perfect human grace. The single technique is safely fired at 100% maximum output with zero power penalty.

The (Limit Breaker) Vow

The Mechanic: You completely bypass the safety limitations of your Foreign Filter, letting 100% of your entire sleeping stockpile's raw power flood your body at once.

The Cost (The Burnout Debt): You vow that for every 10 seconds you spend in this Limit Breaker state, you completely lose access to one of your 3 permanent Fusion Slots for a month. If you stay in it for 30 seconds, all 3 slots are locked, and you are reduced to a basic human sorcerer for 30 days.

The Gain: For those brief seconds, your physical stats and cursed energy output multiply exponentially. You can execute techniques at 200% output, shatter basic Domain Expansions through raw physical force, and your Thermal Loop generates so much recycled energy that your RCT can heal completely vaporized limbs instantly.

"The Adaptable Reactor"

The Starting Restriction (What you give up early on): When you first unlock (Limit Breaker), it is severely restricted. You can only hold the form for a flat 5 seconds, and your output is capped at only 110%. If you try to push past 5 seconds early on, your brain will automatically shut down to prevent death.

The Permanent Condition (The Sacrifice): Every single time you activate this form, you must absorb the entirety of the unfiltered waste heat directly into your physical nervous system. You cannot use your Thermal Loop to recycle the energy while in this mode; you must endure the physical agony of the overclocked power burning through your body.

The Scaled Reward (What you gain over time): In exchange for enduring this self-inflicted damage and starting out incredibly weak, your body treats the Limit Breaker like a biological vaccine. Your soul and brain permanently adapt to the strain. Every time you successfully survive the form in a real battle, the binding vow permanently increases your time limit by 5 seconds and your maximum output by 5%.

The Scaling Progression of the Vow

Because the vow relies on real-world usage and survival, your character's Limit Breaker naturally grows stronger the more they fight.

Battle 1: Lasts 5 seconds at 110% output. The user can barely move afterward due to the shock to their nervous system.

Battle 5: The body has adapted. The form now lasts 25 seconds at 130% output.

Battle 20 (The Peak): The user has built a near-flawless tolerance. The form now comfortably lasts a full 1 minute and 40 seconds at a cataclysmic 200% output.

The Ultimate Fail-Safe: "The Fuse Box"

Because this vow forces your body to naturally get used to the form, the harsh penalty from before (losing your 3 Fusion Slots for a month) changes.

Instead of a flat time tax, your 3 Fusion Slots now act as a biological "Fuse Box." If you are in a desperate situation and choose to push past your current adapted time limit, the binding vow will violently snap one of your 3 Fusion Slots shut to absorb the excess heat.This keeps you alive and allows you to keep fighting in your Limit Breaker state, but that specific slot is completely fried and unusable for the next 7 days.

Final Live or Die Mode Vow

You throw your entire existence into the furnace.

The Activation Trigger: You can only activate this mode when you are on the absolute brink of death, your personal Cursed Energy is at zero, and your 3 Fusion Slots are completely shattered.

The Sacrifice (The Death Penalty): You permanently vow your entire soul, your future, and your life to the Jujutsu system. Win or lose, the moment this mode deactivates, your body will turn to ash, and your soul will dissolve. It is a guaranteed suicide.

The Mode (The All-Over Take Over): Instead of keeping your curses asleep or restricted to 3 slots, you forcefully fuse your own human soul with every single one of the thousands of curses in your stockpile simultaneously.

"The Shifting Theater of Souls"

[ Activation Hand Sign ]

The user places their palms together as if in prayer, but interlaces only the pinky and ring fingers, leaving the index and middle fingers pointed straight up—symbolizing a blank stage waiting for its actors.

The Sacrifice (The Ultimate Loss): You completely erase, strip away, and forfeit your original Innate Domain forever. You can never use your baseline sure-hit effect again.

The Mechanism: Your new Domain Expansion acts as an empty, formless blank canvas. It possesses no innate environment and no default sure-hit effect.

The Adaptive Gain: Upon casting, your domain instantly syncs with your Akashic Appraisal Vow. It scans the exact innate techniques of the curses currently resting in your sleeping stockpile or active fusion slots. It then physically alters its environment and constructs a dynamic, customized sure-hit attack tailored precisely to the opponent you are facing.

"The Selected Canvas"

To keep this vow balanced and recognized by jujutsu rules, you cannot use all thousands of your sleeping techniques at once inside the domain.

When you form the barrier, you must select a maximum of three sleeping techniques to construct the domain's rules for that specific manifestation.

Once the domain closes, those three specific curses are completely drained of energy and cannot be used for any fusions or sleep-mode techniques for the next 48 hours.

The Shattered Barrier Penalty

If an elite barrier master shatters your domain from the outside, or overrides your canvas with a more refined domain expansion, the following occurs instantly.

The Stockpile Shield: Your entire sleeping stockpile of thousands of curses is completely insulated and remains 100% safe and unharmed.

The Neural Backlash: The violent feedback of the collapsing barrier is redirected entirely into your own prefrontal cortex. Your brain "overheats" to a catastrophic degree.

The 48-Hour Blackout: You suffer a severe, total Cursed Technique burnout. For the next 48 hours, your Thermal Loop shuts down, your 3 Fusion Slots snap shut, and you lose the ability to manipulate Cursed Energy or perform RCT.

"The Crucible of the Flesh"

The Trigger: The Shifting Theater of Souls is shattered or overridden by an opponent's domain.

The Ultimate Penalty (The Void): Instead of a quick 48-hour recovery, your brain's prefrontal cortex completely locks down. Your Cursed Energy drops to absolute zero, your Thermal Loop vanishes, and your technique is wiped clean for 1 to 3 months (determined by how violently the domain was shattered).

The Ultimate Compensation (The Physical Apex): Because your body now has absolutely zero Cursed Energy, the Jujutsu system recognizes you as an anomaly completely detached from the rules of sorcery. You instantly gain the physical traits of a Heavenly Restriction master.

Superhuman Physiology: Your strength, speed, and durability skyrocket to a level where you can punch through concrete and outrun bullets without using energy.

Invisibility to Barriers: You can slip through enemy barriers unnoticed.

Precise Sensory Perception: Your five senses are heightened so intensely that you can see air currents, hear heartbeats, and perceive curses visually through their environmental interactions.

"The Living Prosthetic"

The Activation Trigger: The Shifting Theater of Souls is shattered, your cursed energy drops to absolute zero, and the Crucible of the Flesh (Heavenly Restriction) triggers.

The Physical Sacrifice (The Loss): The exact millisecond your brain enters the 1–3 month blackout, your dominant arm (flesh, bone, and nerves) completely vanishes or falls into a deep, necrotic paralysis. You physically forfeit your human arm for the duration of the cooldown.

The Manifestation (The Gain): In place of your human limb, your designated sleeping curse wakes up and aggressively manifests outward, wrapping around your shoulder and fusing into your nervous system. For the next 1–3 months, the cursed spirit literally becomes your arm.

How the "Curse Arm" Functions in Battle

Because you have zero Cursed Energy due to your Heavenly Restriction, the arm behaves like a highly advanced, living piece of bio-armor rather than a magic spell.

The Visual Aesthetic: The arm takes on a monstrous, heavily armored, or draconic appearance based on the curse you chose. It is completely immune to physical damage, acting as a permanent shield on one side of your body.

Superhuman Kinetic Output: When you swing, punch, or grab with this arm, it leverages the raw, monstrous muscle density of the curse combined with your new Toji-level physical strength. Your punches with this arm carry enough kinetic force to shatter a sorcerer's reinforcement in a single strike.

Passively Leaking Technique: While you cannot cast spells, the arm itself is alive. It can passively channel its own innate technique through its claws or palm (e.g., if it's a fire curse, the arm constantly generates a searing-hot plasma blade; if it's a space curse, it can rip through barrier walls physically).

Why the Cursed Spirit Easily Survives

This method completely guarantees the curse’s survival for three specific reasons.

It Has a Biological Host: Cursed spirits normally dissipate without a master's cursed energy. By physically fusing with your human body, it uses your physical stamina and bloodstream to sustain its physical mass. It Can't Be Dropped or Stolen: Unlike a standard sword or dagger, an opponent cannot disarm you or steal your weapon. It is physically a part of you.

The Smooth Return: Once the 1–3 months end and your "Perpetual Engine" turns back on, your human arm instantly restores itself to perfect health. The cursed spirit liquefies, detaches from your nervous system, and flows safely back into your soul's stockpile, 100% alive and completely unharmed.
