Extensiontechniques

An extension is a specific application of an innate technique, worked out by the sorcerer who owns it. Divergent Fist and Black Flash come from the same place. These are the 46 the series names, and the technique each one grows out of.

Bird Strike

神風

Bādo Sutoraiku

Mei Mei's entire fighting style revolves around the gap between what her technique seems to be and what it can actually do. Controlling crows sounds unremarkable, they're weak, small, and individually useless in a fight. But Bird Strike weaponizes a single crow by overloading it with cursed energy far beyond what its body can handle, then launching it as a living missile. The crow dies on impact. The target usually does too. Mei Mei herself calls it the real reason her technique matters. Everything else: the surveillance, the flock control, is preamble. Bird Strike is the punchline.

Biting Twist

咬捻

Kōnen

A finishing technique that puts Savage Jaw Strike's crushing force into a rotational strike. Both hands connect simultaneously with a twisting motion, and the combined torque is enough to shut down a target's consciousness in one clean hit. No build-up, no wind-up, just a precise two-handed impact that puts people to sleep.

Blood Edge

血刃

Ketsujin

Choso shapes his own blood into a blade extending from his arm, essentially giving himself a permanent, retractable melee weapon that can't be disarmed. The hardened blood holds a cutting edge comparable to steel and can be reshaped mid-combat, making it adaptable to different fighting distances and angles. For a technique user whose primary tools are all ranged, blood projectiles, Supernova, Piercing Blood, having a reliable close-quarters option completely changes the matchup calculus. Opponents who rush Choso expecting a ranged specialist find themselves eating sword cuts.

Blood Meteorite

血星磊

Kesseiseki

Blood compressed to the density of stone, then launched at high speed. The projectiles hit significantly harder than normal blood manipulation attacks, each one carries the impact of a thrown rock rather than a splashed liquid. Choso can fire them rapidly and in sequence, maintaining pressure that keeps opponents on the back foot.

Body Repel

撥体

Battai

Mahito's Idle Transfiguration doesn't just work on other people. He can reshape himself at will, turning his own body into whatever the fight demands. Extra arms, blade-like appendages, elastic limbs, hardened sections to absorb impacts: the only limit is Mahito's imagination, and he has plenty. This makes fighting Mahito feel fundamentally unfair. Cut off his arm? He grows a new one shaped like an axe. Land a body blow? That section of his torso goes soft and absorbs the impact. He can split into pieces that move independently, flatten himself to dodge, or inflate his fists to hit harder. Traditional damage simply doesn't stick because he rearranges whatever you broke. The one vulnerability: attacks that target his soul directly bypass all the physical restructuring. This is why Yuji Itadori, who instinctively strikes at the soul level, was the only fighter who could consistently hurt Mahito through Body Repel.

Boost On

推力加算

Būsuto On

A temporary power spike for Mechamaru's puppet body. Kokichi channels extra cursed energy into the mechanical frame, pushing its speed and striking power past normal limits for a short burst. The trade-off is rapid energy drain, useful for breaking a stalemate, dangerous if the fight drags on afterward.

Collapse

瓦落瓦落

Garagara

Nanami's Ratio Technique identifies a weak point at the seven-to-three ratio on any target. Collapse takes that concept and concentrates it into a single maximized hit, all the force directed precisely at the structural flaw, creating an implosion at the point of impact. Think of it as the difference between tapping a crack in a wall and driving a sledgehammer into it.

Convergence

百斂

Byakuren

The loading screen before the kill shot. Convergence compresses blood into a single, impossibly dense point: a tiny sphere that contains enough concentrated force to punch through almost anything once released. It's the required setup step for Piercing Blood, the most dangerous attack in the Blood Manipulation arsenal. The compression requires sustained focus. The blood has to be held in that dense state through continuous cursed energy pressure, which means there's a visible window between starting Convergence and firing Piercing Blood. Opponents who recognize the setup have a narrow chance to interrupt or dodge before the shot releases.

Debut
Episode 19

Crimson Binding

赤縛

Sekibaku

Blood hardened into ropes or tendrils that grab and hold. It's straightforward restraint, wrap the target in blood bindings, lock them in place, then follow up with something that actually kills. The bindings are strong enough to hold most opponents for a few seconds, which is usually all a Blood Manipulation user needs to set up Piercing Blood or get into better position.

Cursed Technique Lapse: Blue

術式順転「蒼」

Jutsushiki Junten・Ao

Blue creates a point of attraction: a vacuum in space that pulls everything toward it. The physics analogy is a localized black hole, though on a much smaller scale. Structures collapse inward. People get dragged off their feet. Matter compresses toward the center. It's the offensive application of Limitless's ability to manipulate space at an atomic level. Beyond combat, Blue functions as a movement technique. By generating a point of attraction ahead of himself, Gojo can slingshot his body forward at extreme speed, essentially falling toward a target of his choosing.

Cursed Technique Reversal: Red

術式反転「赫」

Jutsushiki Hanten・Aka

The mirror image of Blue. Where Blue pulls everything in, Red blasts everything away: a sphere of repulsive force that expands outward and demolishes whatever it hits. The destructive power is roughly double Blue's, which already collapses buildings. Red is notoriously difficult to achieve. It requires channeling positive energy (reverse cursed technique) through an innate technique, something the vast majority of sorcerers never accomplish in their entire careers. The Gojo clan produced generations of Limitless users who never once activated Red.

Cutie Honey

こっちを向いて

Kyūtīhanī

An extension of Heart Catch that weaponizes captured emotions by projecting them outward onto a target. The effect forces the target to experience an overwhelming wave of emotional vulnerability, love, attachment, sentimentality. That disrupts their mental focus and combat readiness.

Death Swarm

死累累湧軍

Shiruru Yūgun

Dagon summons a massive school of fish-like shikigami that attacks from every direction simultaneously. Individually, each fish is weak. Collectively, they're a wall of teeth coming from 360 degrees with no blind spots. The swarm overwhelms through volume. You can't block everything when 'everything' is hundreds of projectiles coming from above, below, and every side. Inside Dagon's domain, the fish gain the guaranteed-hit effect, meaning they don't miss. They track targets with perfect accuracy regardless of speed or evasion. At that point, it stops being a question of 'can you dodge?' and becomes 'how long can you survive getting hit?'

Decay

朽

Kyū

The aggressive form of the Rot Technique. When the Death Painting brothers' poisonous blood makes contact, Decay accelerates the decomposition, eating through living tissue faster than the body can heal. The rot spreads outward from the contact point, destroying flesh progressively while causing extreme pain. Cursed energy provides some resistance, sorcerers deteriorate slower than normal humans, but without treatment or removal of the contaminated tissue, the decay eventually becomes fatal.

Earthen Insect Trance

土虫蠕定

Dochū Zenjō

Kurourushi commands swarms of cursed cockroaches that devour both cursed energy and physical matter. The insects strip targets like piranhas, individually small, collectively overwhelming, impossible to destroy one at a time because there are simply too many. As a cockroach-type cursed spirit, Kurourushi's technique reflects the primal disgust and unease humans feel toward insects. The swarms don't just damage, they horrify.

Ember Insects

火礫蟲

Karekichū

Jogo creates small fire-elemental insects from volcanic matter. Each one flies toward a target and detonates on contact, essentially tiny homing missiles made of magma. They're harder to dodge than conventional flame attacks because they actively track their targets rather than flying in a straight line.

Flowing Red Scale

赤鱗躍動

Sekirin Yakudō

Blood Manipulation turned inward. Instead of weaponizing blood externally, the user supercharges their own circulatory system, increased blood flow, elevated body temperature, amplified physical performance across the board. Speed, strength, and reflexes all jump to superhuman levels. The advanced version, Flowing Red Scale: Stack, pushes the enhancement further at the cost of serious physical strain. The body isn't designed to operate at those levels, and sustained use causes real damage to muscles and organs.

Frost Calm

霜凪

Shimonagi

A flash-freeze that radiates outward from Uraume in all directions. Everything in range, people, ground, air, drops to extreme sub-zero temperatures instantly. At maximum output, multiple targets get encased in ice simultaneously, shut down before they can react. The technique is devastating as an opener because there's no projectile to dodge. The cold simply appears in a radius around Uraume. If you're within range, you're frozen.

Granite Blast

グラニテブラスト

Guranite Burasuto

Pure cursed energy compressed into a projectile and fired at lethal velocity. Ryu Ishigori's output is the highest ever recorded, and Granite Blast is where that number becomes a physical object. Each shot creates impact craters, demolishes structures, and hits harder than anything most sorcerers have ever experienced. There's no trick to it. No elemental property, no special condition, no clever application. Just an absurd amount of energy concentrated into a single point and thrown at whatever Ryu is pointing at.

Hairpin

簪

Kanzashi

Nobara drives a cursed-energy-loaded nail into a target with her hammer. On impact, the nail releases a burst of cursed energy that does damage beyond the physical puncture. Each hit is both a stab wound and an energy explosion: a two-for-one that makes her hammer strikes disproportionately dangerous for their apparent simplicity.

Hollow Technique: Purple

虚式「茈」

Kyoshiki・Murasaki

Blue pulls. Red pushes. Purple erases. The most classified technique of the Gojo clan combines attraction and repulsion into an imaginary mass that removes anything it touches from existence. Not destroyed, not disintegrated, deleted. Where matter was, there is now a clean void. Firing Purple requires channeling positive and negative cursed energy simultaneously through Limitless, making it one of the most technically demanding attacks in jujutsu. The Gojo clan kept its existence secret because even knowing it was possible was considered dangerous information.

Icefall

直瀑

Massive formations of ice materialize above the target and drop. Each falling chunk carries extreme cold that freezes whatever it impacts, combining crushing weight with flash-freeze damage. The technique turns the space above a target into a kill zone, look up and see a glacier falling toward you. Icefall works as a follow-up to Frost Calm's area freeze. Targets already slowed by extreme cold have much less chance of dodging several tons of falling ice.

Instant Spirit Body of Distorted Killing

遍殺即霊体

Hensetsu Soku Reitai

Mahito's final form. By applying Idle Transfiguration to himself with full commitment, he reshapes his body into the optimal combat configuration, faster, stronger, more durable, with every limb weaponized. His arms extend as bladed whips, his body splits and reforms at will, and every point of contact carries the soul-altering touch of Idle Transfiguration. It's what Mahito looks like when he stops playing human and becomes what a cursed spirit of human malice was always meant to be.

Jacob's Ladder

邪去悔の梯子

Yakobu no Hashigo

A column of divine light descends from above and purifies everything it touches. The attack neutralizes cursed energy on contact, it doesn't just damage, it cleanses, making it especially devastating against beings that are made of cursed energy. At maximum output, Jacob's Ladder can critically wound targets that conventional cursed technique attacks barely scratch.

Kaichi

獬豸

Kaichi

The first of Ino's four auspicious beasts. Kaichi provides mid-range offensive capability, cursed energy strikes that let Ino fight at a distance where he can control spacing before committing to close combat. It's his opening move in most fights, the first beast he calls because it lets him assess the situation from relative safety.

Piercing Blood

穿血

Senketsu

The kill shot of Blood Manipulation. After compressing blood to extreme density through Convergence, the user fires it as a beam that moves faster than almost any sorcerer can react to. The compressed blood maintains penetrating force over distance, punching through defenses that would stop conventional attacks. The two-step process, Convergence then Piercing Blood, is both the technique's strength and weakness. The setup is visually obvious to anyone who knows what to look for, creating a narrow window where opponents can dodge before the shot fires. But if it fires and you haven't already moved, you're probably not moving again.

Rapid-fire cursed energy projectiles from Mechamaru's puppet body. The individual shots aren't powerful enough to be lethal against strong targets, but the barrage is sustained and suppressive. It pins opponents down, limits their movement options, and forces them to either tank hits or waste time dodging instead of attacking.

Polymorphic Soul Isomer

幾魂異性体

Kikon Iseitai

Mahito splits off fragments of his soul into independent clones. Each one is a real piece of Mahito, smaller and weaker than the original, but carrying the same Idle Transfiguration touch. One finger from a clone is just as lethal as a touch from the real Mahito. The clones can operate independently across different locations, forcing opponents to split their response teams. A single Mahito is already a crisis. Multiple Mahitos appearing across a city is a catastrophe.

Reiki

霊亀

Reiki

The second auspicious beast from Ino's arsenal. Reiki enhances close-range combat, coating Ino's extremities in cursed energy that increases striking power and provides a distinctive sliding movement across surfaces. The slide makes Ino's footwork unpredictable. He glides rather than steps, changing direction in ways that conventional fighters don't anticipate.

Resonance

共鳴り

Tomonari

Voodoo at its most literal. Nobara drives a nail through a straw doll containing a piece of the target, blood, hair, anything organic, and the damage transfers directly to the target's body regardless of distance. The target gets hit by cursed energy strikes with no warning, no projectile to dodge, and no way to block. Resonance is devastatingly effective because most opponents don't realize they've provided the connection medium. A drop of blood splashed during combat, a severed hair, that's all Nobara needs to establish the link.

The third and apparently strongest of Ino's auspicious beasts. Its abilities were never revealed, Ino's mask was torn off before he could activate it, shutting down Auspicious Beasts Summon entirely. Based on the progression from Kaichi's ranged attacks to Reiki's close-range enhancement, Ryu likely provides an even more significant combat boost. It's one of the series' most tantalizing what-ifs: what would have happened if Ino had gotten Ryu activated?

Tajūkon

Mahito merges multiple transfigured humans into composite bodies: one entity made from several souls welded together. The merged creations are larger, stronger, and more durable than individual transfigured humans, with extra limbs, increased mass, and amplified cursed energy from the combined souls. The composites serve as expendable heavy infantry. They hit harder than normal transfigured humans and absorb more damage before falling apart. From Mahito's perspective, they're just resource management, combining weak units into fewer, stronger units.

蜘蛛の糸

Kumo no Ito

Sukuna weaves multiple Dismantle slashes into an interconnected grid pattern that covers a wide area. Instead of targeting one point, the slashes spread across escape routes and defensive positions like a net. Breaking through one slash exposes you to the three behind it. The technique trades concentrated cutting power for area coverage, each individual slash is weaker than a focused Cleave, but when the entire space in front of you is filled with intersecting cuts, it doesn't matter that each one is individually survivable.

Choso fires blood projectiles from his body in every direction simultaneously. Not forward, not in a cone, outward from his entire body in a sphere. The result is an attack with no blind spot: above, below, behind, every angle covered by high-velocity blood projectiles converging on the target. The multi-directional nature makes Supernova Choso's answer to opponents who are too fast or too tricky to hit with conventional directional attacks. You can dodge a projectile that comes from one direction. You can't dodge projectiles that come from all of them.

Thin Ice Breaker

Usurabi

An amplifier. Thin Ice Breaker compresses space around an attack, any attack, concentrating its force into a smaller point of impact. Like focusing sunlight through a magnifying glass, the technique doesn't add power; it concentrates existing power into a tighter area, dramatically increasing penetration. The technique's versatility is its real strength. It works on punches, cursed energy blasts, projectiles, even other copied techniques. Anything that hits something can hit harder through Thin Ice Breaker.

Ultimate Cannon

三重大祓砲

Arutimetto Kyanon

Seventeen years of cursed energy in a single shot. Kokichi's Heavenly Restriction stockpiled energy throughout his entire life, and Ultimate Mechamaru channeled all of it into one beam.
