Naoya Zenin (Fem)

Naoya Zenin was the youngest daughter of Naobito Zenin and believed herself to be the true heir of the Zenin Clan. Naoya was also the head of the clan's elite unit of jujutsu sorcerers, the Hei.

Naoya was a tall and slim woman with brown eyes and dyed blond hair accented with her dark green roots. She almost always has an arrogant grin plastered across her face and believes herself to have an appearance befitting a clan head, implying she's much better looking than other members like Jinichi. She has four earrings in and on her left ear, two studs along the lobe, and two cuffs along the helix. In the manga, she has two more earrings in her right ear, two studs along the lobe.

Naoya wears a traditional attire that resembles most of her clan members. She sports a white long-sleeved shirt that buttons the color underneath her teal kimono. She completes her outfit with light-colored hakama and waraji sandals, paired with dark-colored tabi socks. When Maki was massacring the Zenin clan, Naoya is seen wearing dark-colored hakama with light-colored tabi socks.

From a young age, Naoya was always praised and told by others that she was a genius. She was severely spoiled as the youngest and most promising of Naobito's children. She was conditioned to view herself as her father's successor and as a result, Naoya's arrogance grew to unbridled levels even as a small child. She looked down on all those she views as weaker than her, which is the vast majority of the people Naoya came across.

The only person Naoya ever appeared to have any respect for was Toji. She went to visit him as a child to mock the pitiful man without cursed energy but was instantly able to recognize Toji was extremely strong in spite of that. This led Naoya to embrace the ideology that the sin of the insignificant is the ignorance of true strength. Naoya felt she was one of the only ones who understood Toji and strived to be as exceptional as he was.

Naoya confidently pursued strength to the point where she viewed everyone else as inferior to herself. She refused to acknowledge anyone's talent, referring to her elders, Jinichi and Ogi, as weaklings despite their experience as senior members of the clan. Naoya's reckless and conceited attitude irritates even her fellow clansmen, to the point where Ogi and Jinichi attacked her for being excessively pompous.

Raised in an environment that breeds superiority, Naoya developed several sociopathic and narcissistic tendencies and strongly embodied all the stigma about the Zenin clan. She has no family values whatsoever other than trying to outdo everyone to become head of the clan. She didn't express any amount of concern for Naobito, her father, on his death bed and has said more than once that she hates all her older brothers as well. Naoya is openly mysandrist, viewing men only as tire changers and husbands, casually telling Mai's mother that a man who can't walk three paces behind a woman should be stabbed in the back.

Upon learning that Megumi Fushiguro usurped her for the head of the clan, Naoya didn't hesitate to plot a way to kill him. Naoya was well aware that her clansmen might prefer Megumi to herself but didn't care at all for their approval. She had no issues attacking Megumi's allies in an attempt to draw him out and was willing to kill them in order to do so.

Naoya set her pride aside momentarily to work alongside Yuta Okkotsu, but only did so to achieve her own self-serving goals. Even after Yuta checked on her after her loss to Choso, Naoya was irritated with the young man for looking down on her.

Dissatisfied with her plans going awry, Naoya took out her irritation with Maki and mocked him repeatedly upon his return to the Zenin clan's property. She called him scum, taunted him for his scars, and devalued him as a person not only for his new appearance but his inability to use jujutsu as well. She called him a lapdog for following Yuta and Megumi, and threatened to abuse her own cousin in the same manner that she used to bully him in the past.

Upon learning of Jinichi and Ogi's refusal to leave Megumi the family fortune, it was confirmed that Naoya was not the clan's first choice. This irritated Naoya, but she was fine with the conspiracy to get rid of Megumi, Maki, and Mai so long as it served her in the end.

Mai sacrificed himself in exchange for granting Maki a body with power comparable to Toji's. As Maki massacred his way through the Zenin clan, Naoya didn't show the slightest hint of distress for her family members. In fact, she was amused by Maki's power and simply teased him for being so ruthless.

Naoya refused to acknowledge Maki as being in the same realm of strength as Toji. That is a title that Naoya desired and she fought Maki to deny him that more than she did to avenge her own clan. Up until the moment she was defeated, Naoya remained in denial and referred to Maki as nothing more than an imposter.

Even after being brutally bested by Maki, Naoya mocked him for not finishing her off. Fate's sense of irony came for Naoya in the form of Maki's mother stabbing her in the back. As Naoya was losing her life in such a pitiful manner, all she could do was use her last words to insult her assailant.

Overall Skill Level: Naoya was a special grade 1 sorcerer and head of the Hei, the Zenin clan's most powerful collective of sorcerers. She was considered to be amongst the pinnacle of talent within one of Big Three Families with strength comparable to her father's. Naoya considers other strong sorcerers within the clan such as Ogi and Jinichi weak compared to herself.

Naoya employed the cursed technique she inherited from Naobito with elite proficiency. It granted her incredible speed that Naoya prided herself on. She combined her strategic intellect with her close combat prowess to quickly overwhelm her enemies without suffering any damage. Naoya had the same knack for timing as hrr father and prioritized gathering speed even more than the former head did.

Naoya generally doesn't fight with weapons because she prides herself on being a sorcerer that uses jujutsu over armed combat. She finds sorcerers that rely on weapons to be shameful and hides the only knife she uses to keep it a secret. Naoya only resorted to cutting Choso with the knife because he proved to be highly resilient to unarmed blows. Naoya believed there was nothing to fear after Choso's injury and this compiling overconfidence lead to her downfall.

Master Hand-to-Hand Combatant: Like her father, Naoya employed the speed granted by her innate technique in combination with her martial arts skills as her main combat style. She did so with masterful skill, striking her opponents with powerful blows before disappearing and then hitting them again before they react. Naoya demonstrated elite-level hand-to-hand combat skills by mainly throwing different types of punches such as chops, backfists, elbows, uppercuts, or combinations of the like in quick succession. Her defensive discipline was sharp as well, allowing her to predict her opponent's attacks and parry them with precision.

Amplified by the speed of her cursed technique, a single body shot from Naoya slammed Choso into a stone pillar with enough force to crack it. Naoya prided herself on defeating her opponents unarmed and relied on enforcing her physical attacks with jujutsu instead.

High Tactical Intellect: Naoya was always been considered to have a genius-level intellect, even as a child. She shared the same talent for strategic timing that Naobito possessed, allowing Naoya to calculate her opponent's moves into each approach she takes.

While working together with Yuta to kill Yuji, Naoya accurately foresaw Choso attempting to block their path. As soon as Yuji began to run away, Naoya prevented Choso from blocking off Yuta and engaged him one-on-one. Naoya saw Choso use Blood Manipulation before their fight and knew her best course of action was to counter Piercing Blood from the start.

Even while obeying Projection Sorcery's 24 FPS rule, Naoya takes into account the possibility of her opponent countering. When Choso adapted to Naoya's speed using Flowing Red Scale: Stack, Naoya quickly recognized this was able to avoid Choso's counteroffensive by accurately predicting his moves. Against Maki's Shiranui-Gata, Naoya deduced it was a trap and wisely decided to avoid a direct confrontation, choosing to continue gaining speed and hold on to her advantage.

Naoya carried a tanto-style knife she kept tucked in her clothes. She held disdain for the use of weapons in general and thus rarely used it, preferring instead to fight unarmed. She was only shown using it once against Choso in an attempt to disable Flowing Red Scale.

Projection Sorcery is an inherited technique passed down in the Zenin Clan from Naobito Zenin to her youngest daughter Naoya Zenin. It traces movement at twenty-four frames per second and traps anyone who disobeys that rule inside a frame for one second.

This technique divides one second into twenty-four frames of animation using the user's field of view as the projection angle of view. The user can trace a predetermined set of movements into those twenty-four frames and execute them in that single second. Moving using this technique makes the user appear to move unnaturally fast, too quick for even special grade cursed spirits to follow.

While Projection Sorcery is active, anything touched by the user's palm must also abide by the "24 FPS" rule while moving. Failure to do so results in the subject getting immobilized and frozen in an animation frame for one second. Although it's just a second, anything caught in that frame is completely vulnerable to attack. Hitting the frame will break the target out of it, usually heavily injuring them.

In addition to its strengths, are several risks to using Projection Sorcery for the user. The predetermined course cannot be adjusted once started. Furthermore, if the trajectory of movement or the laws of physics are excessively ignored, the user will be frozen as well. There is also an upper limit to the user's body acceleration when activating this technique. However, maintaining constant activation of Projection Sorcery allows speed to continually build.

Time Cell Moon Palace is Naoya Zenin's domain expansion using Projection Sorcery.

Expanding this domain casts a black empty area save for a few floating particles and the main stage of the environment. The primary stage of the Time Cell Moon Palace is comprised of a straight path of flesh that leads to a large eye behind the caster. The overall design of this domain strongly resembles a womb.

The auto-hit function of the domain injects films of animation frames into the neck of its targets. Anyone who moves within the domain must abide by the 24FPS rule of Projection Sorcery or they will receive numerous bloody injuries with every movement.

The domain increases the precision of the embedded cursed technique and targets individual cells. Freezing individual cells disrupts them and causes countless small cuts and gashes to appear all over the body, completely immobilizing any target. Forcing a movement can cause an appendage to be cut off completely

Cursed Techniques are abilities fueled by cursed energy. Different types include innate techniques, barrier techniques, shikigami, New Shadow Style, and more.

A cursed technique is activated through the act of pouring cursed energy into it, utilizing one of two processes; Lapse or Reversal (Reversal is only accessible when the technique has a clear cut opposite, like blue and red, light and dark, cold and hot, that sort of thing). 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 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 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.

Anti-Domain Techniques 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 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.

Esoteric art: Hollow Wicker Basket: The predecessor to New Shadow Style: Simple Domain that erects a spherical barrier in the appearance of a woven basket surrounding the caster. The technique neutralizes an expanded domain's barrier to nullify its can't-miss attack.

New Shadow Style: Simple Domain: Developed by Sadatsuna Ashiya during the Heian Era as the "domain for the weak". It expands a small domain and nullifies an enemy's can't-miss attack within its range by neutralizing the domain's barrier.

Secret Art: Falling Blossom Emotion: A secret domain countermeasure passed down in the Big Three Sorcerer Families. Rather than expanding a domain, Falling Blossom Emotion counterattacks with cursed energy the moment a domain's can't-miss attack makes contact.

Domain Amplification: Envelops the user's body in a thin veil of their domain and automatically nullifies any cursed technique it comes into contact with. A caster cannot use Domain Amplification and their innate technique at the same time.

Reverse Cursed Technique is a special type of cursed technique that converts cursed energy into positive energy primarily used for healing injuries.

Reverse cursed technique turns cursed energy into positive energy to regrow missing body parts and heal wounds. Cursed energy comes from negative emotions, unfit for healing living things. Reverse cursed technique uses the principle of multiplying a negative by another negative to produce a positive. While cursed energy flows from the gut, the brain directs reverse cursed technique. Positive energy can reproduce blood, bone, flesh, and organs, allowing proficient jujutsu sorcerers to recover entire limbs and withstand powerful attacks. The speed and effectiveness of this process are dependent on the user's cursed energy output. Reverse cursed technique can also remove toxins from a sorcerer's body and heal damage to their soul, though both of these skills are even more difficult than simple regeneration.

Reverse cursed technique is extremely complex and difficult for most jujutsu sorcerers to perform. One of the primary hurdles when using it is compensating for blood loss through a technical process that converts a massive amount of cursed energy into blood. Individuals who are naturally capable of doing this, namely the Cursed Womb: Death Paintings, can learn to use reverse cursed technique much easier than others and use it without the drawback of large energy consumption.

Most reverse cursed technique users can only heal themselves, as it is more efficient and less difficult to perform than healing other people. One reason is the fundamental difference in application. Another is because the cursed energy of the healer and the receiver can be incompatible due to the receiver's body rejecting the healer's cursed energy or failing to respond to the conversion. Due to this, the effectiveness of healing other people is case-by-case.

Cursed Energy is a form of spiritual energy that leaks from humans as a result of their negative emotions. It makes up the bodies of cursed spirits, and is utilized by jujutsu sorcerers and curses alike to fuel their jujutsu.

Negative emotions such as fear, grief, anger, hatred, and envy are the foundation of cursed energy. These emotions exist to some degree within most humans and as a result, the vast majority of human beings possess cursed energy. If this amount is higher than a certain degree, it grants the person the ability to see cursed spirits. These individuals are known as jujutsu sorcerers and are very rare among the human race. Cursed energy leaks from the human body, accumulates, and ferments over time until a cursed spirit manifests. This is only the case with non-sorcerers, as sorcerers are trained to control and channel their cursed energy into jujutsu.

Cursed energy is the primary power source for any sorcerer or cursed spirit; sorcerers voluntarily produce said energy akin to the generation of electricity, and since negative emotions are the trigger, sorcerers train to create cursed energy from the slightest spark of emotion. Cursed tools, cursed objects, and cursed corpses all contain cursed energy as well. It is ordinarily used to fuel cursed techniques, reinforce the body, or activate talismans, but cursed energy has various uses. The properties of cursed energy vary from person to person and its connection to the human brain is shrouded in mystery. In the anime, most cursed energy is blue in color but there are several exceptions.

Black Flash (Kokusen) is a phenomenon in jujutsu that greatly amplifies the user's physical strike when cursed energy is applied to it within one-millionth of a second.

Black Flash is a distortion in space that occurs when cursed energy is applied within 0.000001 seconds of a physical hit. When a jujutsu sorcerer is able to achieve this, their cursed energy flashes black, and the destructive power of their strike is equal to a normal hit to the power of 2.5.

Domain Expansion is an advanced barrier technique and is considered the pinnacle of jujutsu sorcery. It manifests the user's innate domain into reality inside a barrier infused with their innate cursed technique. Within a domain expansion, the user's cursed techniques are improved and any that are activated are guaranteed to hit.

Domain Expansion is the most supreme technique of any jujutsu user. It is achieved by expanding one's innate domain with cursed energy while using a barrier to construct it inside a separate space. The caster then imbues their cursed technique within the barrier to complete the expansion, allowing them to deploy their innate ability throughout the entire domain.

A specific hand sign or signal unique to the user is required to expand someone's respective domain. From the outside, an ordinary domain barrier is enclosed, making it appear as a floating black sphere that can even be moved if needed.

Domains that are expanded to be lethal are constructed within a barrier imbued with the user's cursed technique. The caster's abilities are amplified and any cursed techniques deployed within the domain are guaranteed to hit their target. This "guaranteed-hit guaranteed-kill" factor is derived from the barrier's embedded technique, which is what makes this type of domain considered lethal. These sure-hit attacks even bypass Satoru Gojo's Infinity.

In the past, Domain Expansion was a more common technique because domains weren't constructed to be fatal. They were only imbued with a guaranteed-hit effect, which forced targets inside to obey the rules of the embedded cursed technique. As more domains were constructed to be lethal and include guaranteed-kill effects, the number of users greatly decreased over time. Hiromi Higuruma's Deadly Sentencing is an example of an old-style, non-lethal domain that forces his opponent into a trial.

Not all guaranteed hits necessarily enforce rules on targets in the domain. Kinji Hakari's domain possesses a sure-hit effect, but it only transfers information to its target in exchange for faster technique activation and strength in a clash of domains.

Innate domains that are expanded using only cursed energy without an embedded cursed technique are incomplete even if they include a barrier. In most cases, the same applies to domains without a fully enclosed barrier. Closing the barrier fully integrates the embedded technique into the domain and enables its sure hit effect. Without that, the caster will only receive an improved cursed technique without a sure-hit effect. Barriers forcibly enclosed using the shape of an outside environment also do not incorporate sure-hit effects.

After using a Domain Expansion, a effect known as Cursed Technique Burnout occurs, where essentially using a technique is borderline impossible for a certain amount of time, varying between each person. During burnout, if a technique is used, it will disappear soon afterwards or simply not work.

A Binding Vow is a pact made by jujutsu users that creates conditions for themselves or agreements with others.

Binding vows are considered by all jujutsu users to be one of the essential tenets of jujutsu sorcery. They are, in essence, contracts that an individual can form with themselves or with another person. By adhering to the rules and restrictions established in these contracts, a user can gain increased power or achieve a specific goal; however, breaking a binding vow has consequences.

Self-imposed binding vows involve specific risks and conditions placed upon oneself in exchange for a corresponding benefit. For example, revealing how one's cursed technique functions can increase its effectiveness, while willingly limiting one's cursed energy for a set period can enhance its output outside that timeframe. The penalty for breaking a self-imposed binding vow is the loss of whatever benefit was gained through the contract, though unbreakable binding vows that permanently adjust a user's abilities can be made.

In addition to innate techniques and cursed energy, binding vows can also be used to customize barrier conditions, though doing so requires considerable skill in barrier techniques. For instance, a barrier can be constructed with a vow that excludes a specific individual while allowing others to enter in exchange. Alternatively, a barrier's durability can be reinforced by placing the caster or its source outside the barrier in an obvious location, thereby increasing the risk of being discovered and attacked.

Unlike self-imposed vows, binding vows made between two or more individuals function primarily as mutual restrictions that ensure compliance with an agreed-upon contract rather than directly enhancing abilities. All parties must willingly agree to the terms, meaning no one can be forced or coerced into forming such a vow through threats or intimidation. While the exact consequences of breaking a binding vow with others remain unknown, they are believed to be far more severe than those of a self-imposed vow.
