Cursed Technique

**Cursed Techniques** ( *Jutsushiki*?) are abilities fueled by cursed energy. Different types include innate techniques, barrier techniques, shikigami, new shadow style, and more.

## Technique Activation

A cursed technique is activated through the act of pouring cursed energy into it, utilizing one of two processes; **Lapse** or **Reversal**. If cursed energy is comparable to electricity, cursed techniques are the appliances that use that power to function. Cursed energy is processed through a procedure akin to a mathematic formula within the user to activate a cursed technique.

### Lapse

**Lapse** (順転 *Junten*?, lit. "*Forward Rotation*") refers to the basic, default, or neutral state of activation for a cursed technique. To activate a cursed technique through lapse, the caster circulates their cursed energy in a forward direction to channel it into their ability.

### Reversal

**Reversal** (反転 *Hanten*?, lit. "*Reverse Rotation*") produces positive energy by multiplying negative energy with negative energy. Negative energy isn't suitable for recovering but positive energy can heal physical injuries. However, it requires highly sophisticated manipulation of cursed energy to achieve, so the ability to do so is rare.

### Subtraction

Cursed techniques often require hand signs, empowered words, or other gestures to activate. A sorcerer's skill is determined by the degree to which they can minimize and omit these components to make their abilities more efficient. Conversely, the purposeful inclusion of incantations or rituals can elevate a cursed technique's effectiveness.

## Innate Techniques

**Innate Techniques** ( *Shōtoku Jutsushiki*?) are unique abilities congenitally engraved into the user's body, specifically in the right prefrontal cortex of the brain. Most jujutsu sorcerers are born with an innate technique that manifests around the age of five or six, which continually carves its formula into the user over time.

Innate techniques are proprietary and comprise eighty percent of a sorcerer's intrinsic skillset, making them nearly impossible to mimic, not unlike a copyrighted computer program. When an individual refers to their own personal cursed technique, they're generally talking about their innate technique.

In almost all cases, an individual possesses only a single innate technique. In especially rare cases, someone may possess more than one. Kenjaku, who can switch bodies, has access to the technique carved into the body of his vessel. However, even can only possibly possess a maximum of three to four innate techniques at one time. Yuta Okkotsu can only utilize numerous techniques because Rika serves as his external aid. Otherwise, too many innate techniques will overload the user's brain.

## Non-Innate Techniques

Cursed techniques that aren't considered innate techniques are ubiquitous skills that anyone with enough cursed energy can learn to use with enough training. However, the aptitude for learning them differs from person to person. These include barriers techniques, shikigami jutsu, and new shadow style among other techniques.

### Inherited Techniques

**Inherited Techniques** ( *Sōden Jutsushiki*?) are innate techniques passed down to sorcerers in the same bloodline. While sorcerers who don't come from prominent clans can inherit innate techniques, e.g. Straw Doll Technique, those obtained hereditarily from the ancestors of the Big Three Families especially carry the title of inherited technique, e.g. Limitless. The Big Three Families have maintained their authority and prestige by passing down powerful techniques to their descendants. Therefore, a sorcerer with an inherited technique is guaranteed an important position in the family.

Inherited Technique users have the advantage of being equipped with a manual on how to use them. However, passing down a technique through generations also presents the issue of other groups learning how the ability works, along with its shortcomings.

#### Non-Inherited Techniques

While the formula for hereditary innate techniques is only accessible to members of their respective clan who inherited the engraving, innate techniques often manifest naturally within sorcerers regardless of their heritage. Suguru Geto, Kento Nanami, and Aoi Todo all possess innate techniques despite being born to non-sorcerer families.

### Extension Techniques

**Extension Techniques** ( *Kakuchō Jutsushiki*?) are original abilities derived from innate techniques. Innate techniques cannot be changed or altered, but they can be trained and expanded on through creativity to maximize their applications into extension techniques. E.g. Collapse is a more powerful application of Kento Nanami's Ratio Technique. In the case of inherited techniques, sorcerers pass down the original moves that they create. E.g. Blue and Red of the Limitless.

**Maximum Output** ( *Shutsuryoku Saidai*?): Extension techniques with the highest possible cursed energy output channeled into them. Not to be confused with Maximum Techniques, these moves are also titled Stack ( *Sai*?).

**Maximum Techniques** ( *Gokunoban Jutsushiki*?): Extension techniques that realize the greatest potential of their derived innate technique. They are the most supreme art of any sorcerer outside of domain expansion, e.g. Suguru's Maximum: Uzumaki is the maximum technique of his Cursed Spirit Manipulation

### Barrier Techniques

**Barrier Techniques** ( *Kekkai Jutsushiki*?) are cursed techniques that employ barrier zones to trap entities within a space or to prevent them from entering one. Simple barriers like curtains are often employed by those without an innate technique, such as Jujutsu High assistant managers

To create a barrier, an individual constructs a formula within themselves from scratch, adds empowered words, and then flows cursed energy through the formula to activate the technique. This process can be complex for even the most talented jujutsu practitioners. Many strong sorcerers with innate techniques can't perform barrier techniques. E.g. creating a barrier is simple enough, but making it so only certain people can exit requires advanced skills.

### Anti-Domain Techniques

**Anti-Domain Techniques** (の *Tairyōiki no Sube*?) are countermeasures designed to withstand the can't-miss attack of opposing domain expansions. They are mainly designed for those who cannot expand their own domain for any reason.

**Secret Arts** (秘伝 *Hiden*?) are unique anti-domain techniques passed down in the Big Three Sorcerer Families. Having existed for millennia, the Big Three Families have accumulated many secret skills for dealing with cursed spirits and curse users.

### Shikigami Jutsu

**Shikigami Jutsu** (?) conjures shikigami to aid the user using a variety of methods. Simple shikigami can be summoned by any capable sorcerer, but some innate techniques revolve around a summoning shikigami as well, such is the case with Moon Dregs.
