Innate Technique: Accelerator (Vector Transformation)

This is an Innate technique that I made for my text based JJK TTRPG. Cursed energy trait was randomized and I somehow got Electric CE. CE Color was randomized and I got sakura pink. I do not have the six eyes, but I know that this probably would be way better with it. Im just here to share to yall the innatw technique and see what yall think about it.

PS: This innate technique is heavily based on Toaru’s Accelerator.

PS: I had to remove my character’s name when copy pasting this and replace it with “The user”, They/Them/Theirs, He/She. Sorry if I missed out on some or if grammar is off.

INNATE TECHNIQUE: ACCELERATOR (VECTOR TRANSFORMATION)

Every phenomenon in the universe that possesses motion or force has a "Vector"—a quantity defined by both Magnitude (how much/how fast) and Direction (where it is going). This applies to kinetic energy (a fist, a bullet, a falling rock), thermal energy (the dispersion of heat), electrical energy, and crucially, Cursed Energy. Cursed Energy flows; it has momentum, density, and trajectory.

The Innate Technique Accelerator allows the user to perceive these vectors as tangible, manipulatable lines of force. By applying Cursed Energy to an object or phenomenon the user is in direct physical contact with, they can alter its vector—changing its direction, its magnitude, or both.

Because vectors govern the very laws of physics, this technique requires an ungodly amount of calculating power. The brain must constantly process the mass, velocity, CE density, and trajectory of anything interacting with them.

NEUTRAL STATE: VECTOR REFLECTION (PASSIVE)

The Neutral State of an Innate Technique is its baseline, unamplified application. For the Limitless technique, the Neutral is "Infinity" (the convergence of space). For the Accelerator technique, the Neutral is "Vector Reflection."

Mechanics of Vector Reflection:

The user covers his body in a micro-thin, form-fitting film of Cursed Energy. This film acts as a sensory boundary and a calculation matrix. When a foreign vector (an incoming attack, a curse's claw, a blast of fire) makes contact with this film, the user technique instantly calculates the vector's properties and violently reverses its direction while maintaining or amplifying its magnitude.

If a Grade 2 Cursed Spirit attempts to punch the user in the face, the kinetic force of its fist hits the CE film. The technique calculates the force (e.g., 5,000 Newtons of force aimed inward), and flips the vector 180 degrees. The fist is instantly repelled backward with 5,000 Newtons of force aimed outward, effectively shattering the curse's own arm with its own strength.

The Filter & The Whitelist:

If Vector Reflection were perfectly absolute, the user would die. They would reflect gravity and float into space; They would reflect oxygen and suffocate; They would reflect light and be blind; They would reflect ambient heat and freeze to death.

Therefore, The user must maintain a subconscious Whitelist. Their brain is constantly sorting incoming vectors into two categories: "Harmful" and "Harmless."

• Harmless (Allowed): Gravity, standard atmospheric pressure, oxygen, visible light, standard ambient temperature, soundwaves (at non-damaging decibels).

• Harmful (Reflected): High-velocity kinetic impacts, intense thermal radiation, hostile Cursed Energy signatures, toxins, and abnormal atmospheric pressure.

Because the user’s subconscious is constantly running these calculations, they are prone to mental fatigue. If their brain is overloaded (via extreme sensory attacks, complex Domain guaranteed hits, or physical exhaustion), the filter might fail, forcing him to drop the shield or risk reflecting essential elements like oxygen.

Calculation Cap:

If an attack involves variables The user cannot calculate (e.g., an Innate Technique that erases space, or an attack with zero physical mass or CE flow), they cannot reflect it.

Cursed Tools:

Weapons infused with highly disruptive CT/CE (like the Inverted Spear of Heaven or the Black Rope) will bypass the calculation film and strike true.

EXTENSION TECHNIQUES (ACTIVE NEUTRAL)

While Vector Reflection is passive defense, the Neutral state can be used actively by voluntarily touching an object and manually overriding its vector. These are classified as Extension Techniques of the Neutral State.

Kinetic Transference ("Earthquake Stomp")

By stomping his foot onto the ground, The user can take the downward vector of his kick and artificially multiply its magnitude, transferring that vector into the earth. They can then redirect the direction of that force to travel horizontally through the ground and erupt beneath a target.

• Execution: The user channels their CE to the sole of their shoe, calculates the density of the concrete/earth, and stomps. The ground shatters, creating a localized shockwave or a targeted eruption of debris.

• Combat Application: Area of Effect (AoE) crowd control. It destroys footing and launches smaller curses into the air.

Projectile Acceleration (“Railgun”)

The user does not need cursed tools or guns; the environment is their armory. By picking up any small object (a pebble, a coin, a shard of glass), they can apply the Innate Technique to the object's kinetic vector. With a simple flick of their finger, they assigns a massive velocity vector to the object, firing it at speeds rivalling or exceeding a high-powered sniper rifle.

Aerokinesis

Air has mass and movement. By manipulating the vectors of the air currents immediately surrounding the user’s body, they can create gale-force winds.

• Execution: The user sweeps their arm, grabbing the vector of the surrounding air, and thrusts it forward. A compressed blade of air shoots out, or a localized tornado forms around them to deflect gas/spores.

• Combat Application: Pushing enemies away, clearing toxic gases, or creating vacuum blades.

Bio-Vector Manipulation

A lethal, close-quarters application of the Neutral state. The human body is full of moving vectors: blood flowing through veins, electrical impulses traveling through nerves. If The user makes direct, skin-to-skin contact with an opponent, they can inject their CE into them and manually reverse their internal vectors.

• Execution: The user touches a Curse User's chest. They calculate the flow of blood entering the heart and reverses the vector. The blood violently flows backward, tearing arteries and causing catastrophic internal ruptures.

• Combat Application: An execution move or severe debuff. Requires grappling or a successful unarmed strike.

SYNERGY:

Your randomized Cursed Energy trait is Electric/Shocking (Sakura Pink). This radically alters how the Accelerator technique manifests and feels in combat.

Because your raw CE naturally possesses the properties of electricity, your vector manipulation has a secondary, terrifying layer.

• Plasma Friction: When the user uses Projectile Acceleration (the pebble railgun), the friction of the object moving at Mach speeds, combined with his Sakura Pink electric CE, turns the pebble into a streak of pink plasma. It deals additional lightning damage and cauterizes the wound instantly.

• Electromagnetic Redirection: The user’s brain has an easier time calculating and manipulating metallic objects and electrical currents. If an enemy uses a technique based on lightning or magnetism, the user’s calculation time is halved, allowing him to reflect it flawlessly without draining theit mental stamina.

• The Neural Override: By applying his Vector control to their own electric CE trait, the user can force his CE to travel through their own nervous system at accelerated speeds. This acts as a minor, temporary buff to their Dexterity and reaction time, allowing their body to keep up with his brain's calculations.

THE MENTAL TOLL

To balance this overwhelming power, we must enforce the laws of Jujutsu. The brain is flesh. The Prefrontal Cortex can only process so much information before it overheats.

• Calculation Fatigue: If the user is subjected to an attack with too many overlapping, chaotic vectors (e.g., a swarm of a thousand tiny shikigami, or an explosion of shrapnel from 360 degrees), their brain must process thousands of calculations in a microsecond. If the user fails, they takes a burst of psychological damage (headaches, nosebleeds) and their Vector Reflection shield drops the brain reboots the calculations.

CURSED TECHNIQUE LAPSE: VECTOR OVERRIDE

In Jujutsu theory, the "Neutral" state of an Innate Technique is its resting manifestation—for Accelerator, the passive calculation and reflection of incoming force. Cursed Technique Lapse (Forward Rotation) occurs when a sorcerer actively pumps standard, raw Cursed Energy into their innate etched formula to project the technique outward, forcing its rules upon the environment aggressively.

If the Neutral state is a shield that reverses vectors upon contact, the Lapse state is a sword.

Lapse, designated for this technique as Vector Override, allows the user to actively command the magnitude and direction of any vector he/she touches, regardless of its original state. They do not need an attack to strike them first; They can initiate the calculation and impose new physics onto stationary or moving objects, multiplying their force exponentially or twisting their directional laws.

Lapse Extension: Absolute Velocity

The user applies Forward Rotation to their own kinetic vector or the vector of an ally/object. By multiplying the magnitude of his forward momentum, he achieves instantaneous, explosive movement that registers to the human eye as teleportation.

• Execution: User channels CE into their legs, calculates the friction of the ground, the air resistance, and the structural integrity of his bones, then multiplies their velocity vector by a factor of 10. The ground craters beneath him as he launches.

• Combat Application: Closing distances instantly, escaping area-of-effect expansions, or adding catastrophic kinetic force to a melee strike.

Lapse Extension: Torsion

A gruesome, close-quarters application of vector manipulation. By grabbing an opponent, The user calculates the internal vectors of their muscle fibers, bones, and blood vessels. They then apply conflicting directional vectors to different segments of the limb—forcing the top half to rotate violently clockwise while the bottom half rotates counter-clockwise.

• Execution: The user grabs the forearm of a Curse. They activates Lapse. Sakura Pink electricity surges into the Curse's flesh. The vectors snap. The arm instantly twists like a wet towel being wrung out, shattering bone, tearing ligaments, and shredding muscle in a microsecond.

• Combat Application: Disabling limbs, severe single-target damage, execution.

Lapse Extension: Vector Crush

Gravity is a constant downward vector. By placing their hand on a surface or a target, the user can take the ambient gravitational vector and multiply its magnitude drastically within a localized area, effectively creating a zone of crushing weight.

• Execution: The user slams their hand into the floor. They isolates the gravitational vector in a 15-foot radius centered on their point of contact and magnifies it by 50 Gs. The air distorts. The concrete shatters under its own weight. Anything caught inside is violently slammed into the earth.

• Combat Application: Area-of-Effect crowd control, pinning highly agile targets, or neutralizing aerial combatants.

Lapse Extension: Plasma Vortex

This is a high-tier extension leveraging the user’s specific genetic mutation: their Electric/Shocking Cursed Energy trait. Heat is simply the vector of atoms vibrating. By manipulating the vectors of the air molecules in front of them, the user forces them to collide at hyper-accelerated speeds. When combined with the user’s highly charged Sakura Pink Cursed Energy, the resulting friction instantly ignites the oxygen into a localized sphere of blinding, superheated plasma.

• Execution: The user compresses the air vectors between his palms, locking their directional escape and multiplying their collision magnitude. The air shrieks, turning into a stabilized ball of pink lightning and white-hot plasma. The user then forcefully alters the sphere's trajectory, launching it at the target.

• Combat Application: Devastating ranged area damage. Armor penetration.

Lapse Extension: Vector Lock

Instead of adding magnitude or changing direction, the user reduces a kinetic vector's magnitude to absolute zero.

• Execution: The user catches a swinging blade or a moving projectile. he/she calculates its kinetic energy and actively injects opposing CE to reduce its vector magnitude to exactly 0. The object loses all momentum instantly and hangs dead in the air or their grip.

• Combat Application: Neutralizing momentum-based attacks, stopping falling debris, or locking an opponent's weapon in place mid-swing.

CURSED TECHNIQUE REVERSAL: SCALAR IMPOSITION

To achieve Cursed Technique Reversal, a sorcerer must first possess the ability to generate Reverse Cursed Technique (RCT)—Positive Energy. This is achieved by taking negative Cursed Energy and multiplying it against itself (Negative × Negative = Positive). This mathematical operation requires extraordinary neurological processing.

If the Lapse (Forward Rotation) of Accelerator dictates Vector Override (adding, multiplying, or directing vectors), the Reversal of the technique dictates the destruction of the vector concept itself.

A vector possesses Magnitude (amount of force/speed) and Direction (trajectory).

Cursed Technique Reversal: Scalar Imposition strips the "Direction" entirely, leaving only "Magnitude." In physics, a quantity with only magnitude is a Scalar. When you strip the direction from a kinetic force moving at 500 meters per second, that forward momentum has nowhere to go. It instantly violently expands omnidirectionally.

CTR Extension: Omnidirectional Rupture

The user intercepts an incoming directed force (a physical blow, a projectile, or a concentrated beam of Cursed Energy) and injects it with Positive Energy. he/she instantly deletes its directional vector. The stored magnitude of the attack violently detonates at the point of contact as a 360-degree scalar shockwave.

• Execution: A Grade 1 curse lunges with a devastating piercing strike. The user catches the strike, applies CTR, and removes the forward direction. The kinetic energy of the curse's own mass and speed explodes outward in a perfect sphere, blowing the curse's arm off and shattering the surrounding environment.

• Combat Application: Devastating point-blank counter-attack and Area of Effect (AoE) disruption.

CTR Extension: Absolute Anchor

Friction is a vector force that opposes movement. By injecting Positive Energy into the molecular boundary between an object and the environment, The user reverses the concept of kinetic slipping. he/she creates a state of "Infinite Friction," stripping an object's ability to have a directional vector relative to its current surface.

• Execution: The user touches a fleeing enemy, a moving vehicle, or an airborne weapon, and applies CTR. The target’s kinetic vectors are forcibly reduced to a localized scalar zero. The object is violently, instantly anchored in space.

• Combat Application: Absolute immobilization, halting momentum, or creating lethal traps (e.g., anchoring a curse's torso while its lower half is still moving forward at high speed, tearing it in half).

CTR Extension: Phase Shift

The inverse of Absolute Anchor. Instead of creating infinite friction, the user strips the collision vectors between their own body and the physical environment. By wrapping themseleves in a dense film of Positive Energy, they removes their body's ability to mechanically interact with solid matter.

• Execution: The user approaches a reinforced steel wall or an unblockable physical attack. he/she applies CTR to their own atomic structure. They simply walks through the wall or allows the attack to pass through their chest without interacting with their organs.

• Combat Application: Absolute evasion, infiltration, and repositioning.

CTR Extension: Cellular Reconstruction

All sorcerers who grasp Positive Energy can use standard Reverse Cursed Technique to heal. However, The user’s Accelerator calculation matrix allows for unprecedented efficiency. By treating cellular damage as a "negative health vector," The user uses CTR to mathematically force the cells to revert to their unbroken scalar baseline.

• Execution: The user suffers a severed arm. He/She isolates the damaged tissue's coordinates, applies Positive Energy, and calculates the exact biological vector required for cellular mitosis, regrowing bone, muscle, and skin in a fraction of a second.

• Combat Application: High-speed self-regeneration and trauma stabilization.

CTR Extension: White Corona (Synergy Application)

This utilizes the inverse of the user’s Sakura Pink Electric CE trait. Electricity inherently requires a current—a directed vector of electrons. By applying CTR to their own Electric CE, the user strips the current. The electricity becomes a localized, stationary field of pure, undirected Positive electromagnetic energy.

• Execution: The user compresses their CE, turns it Positive, and releases it. It manifests as a blinding, localized sphere of white-gold light hovering in space. It does not travel. It simply exists as a lethal hazard of scalar radiation.

• Combat Application: Area denial, anti-curse traps, and passive damage zones.

Maximum: Plasma Quasar (Absolute Convergence)

Theory: You utilize your Sakura Pink Electric CE trait in tandem with absolute vector multiplication. Instead of altering a single object's vector, you target the kinetic, thermal, and atmospheric vectors of a 100-foot radius. You force every ambient vector—air pressure, ambient heat, light, and localized gravity—to converge on a single microscopic coordinate in front of your palm. The magnitude is multiplied until the sheer friction and density ignite into a localized, artificial quasar of superheated pink plasma and gravitational shear.

• Execution: You form a specific two-handed mudra (representing the mathematical symbol for Infinity/Convergence). The environment instantly goes cold and silent as all kinetic energy is sucked into the focal point. You then release the lock, firing the compressed quasar as a sustained, hyper-destructive beam. The attack instantly permanently alters the terrain. Water is flash-boiled, earth is fused into glass, and barriers Grade 2 or lower are instantly shattered.

IMAGINARY TECHNIQUE: THE MATHEMATICAL PARADOX

An Imaginary Technique is the rarest form of Jujutsu, achieved only by smashing Forward Rotation (Lapse) and Reverse Rotation (CTR) together.

• Lapse (Vector): Magnitude + Direction.

• Reversal (Scalar): Magnitude + 0 Direction.

When you simultaneously generate a Vector and a Scalar of the exact same output and force them to occupy the exact same spatial coordinate, reality breaks. You create a mathematical paradox: a force that possesses infinite directionality but zero physical existence. It is an Imaginary Vector.

Imaginary Technique: Complex Zero (The Erasing Fault)

Theory: You merge the Lapse with Reversal. The resulting fusion manifests as a sphere of absolute, light-consuming void—a tear in the Euclidean geometry of the world. It does not "hit" or "push" the target; it simply deletes the spatial coordinates the target occupies. If the coordinate ceases to exist, the matter inside it is mathematically erased to correct the error.

• Execution: You hold out both hands. In the right, Lapse (Pink). In the left, Reversal (White). You clap your hands together. A silent, frictionless sphere of distorted space forms. You point your finger, and the sphere travels along an unalterable trajectory.
