Zoldyck family

Special legal status *: Hunters' actions, even those resulting in death and destruction, are usually considered justified and do not result in prosecution (although repeated unjustified killings may still result in prosecution).

• Access to classified information *: lists of wanted criminals, data on new species of animals, and other information available only to Hunters.
• High value of a license as an asset *: it can be sold to collectors for a huge sum (enough to cover a luxurious life for several generations), or used as collateral for an interest-free loan of 100 million dollars.
• Authority and job opportunities : the very fact of having a license makes it easy to get any job, and outstanding Hunters can receive star ranks (One Star, Two Stars, Three Stars) for special achievements.

The Hunter Exam *is an annual test required to earn a Hunter's license and become a member of the Hunters' Association.

What is this exam?

It is an extremely difficult and dangerous test: statistically, only about 1 in 10,000 candidates passes, and deaths during the exam are not uncommon. The exam takes place in a new location every year, and the tasks vary—on average, it consists of 5-6 stages.

Before the main exam, unofficial preliminary screenings are often held: Association scouts weed out obviously unsuitable candidates. For example, those who fail a basic test (such as surviving a storm on a ship) may simply not be allowed to take the exam.

During the exam itself, examiners—experienced Hunters—monitor the participants. Each candidate is given a badge with a number and a built-in transmitter, allowing the committee to track their location. They are assessed not only on their performance on tasks but also on their personal qualities: physical abilities (strength, agility, endurance), mental acuity (flexibility of thought, creativity), and overall impression (potential as a Hunter).

Different exam seasons feature different types of tests—for example:

• testing endurance and skills for navigating difficult terrain;
  *encounters with dangerous animals or creatures, where both courage and analytical thinking are important;
• logical problems, searching for traps, testing intuition;
  *tasks for competition and hunting in a confined space;
• final one-on-one duels.

What do those who pass the exam receive?

The main prize is the Hunter's License *. It grants its owner significant privileges:

• Free access to most public services *(approximately 95% of organizations provide services free of charge, the rest at a significant discount), with service provided at first-class standards.
• Freedom of movement *: Hunters are allowed to enter approximately 90% of countries with restricted access and 75% of areas closed to the general public.
• Special legal status

Types of Hatsu (6 categories)

Hatsu type is determined using the "glass of water and leaf test." It reveals the user's natural inclination:

• Enhancement (Kyoka) - increases physical parameters: striking power, speed, regeneration. Example: Gon Freecss.

• Transformation (Hank) - changes the properties of the aura (turns it into electricity, makes it sticky, etc.). Example: Killua Zoldyck (electricity), Hisoka (elastic/sticky aura).

• Emission (Hoshu) - allows one to separate aura from the body and use it remotely. Example: Illumi Zoldyck.

• Manipulation (Sosa) – control over objects and living beings. Example: Shalnark (Nen-phone).

• Materialization (Genjutsu) - the creation of physical objects from aura. Example: Kurapika (Chain of Judgment).

• Specialization (Tokushin) - unique abilities that don't fit into other categories. Example: Kuroro Lucifer (ability theft).

Important additional techniques

• En (円, "circle") - expands the aura into a sphere around oneself to sense everything within it. Allows one to detect enemies, but lacks dense defense.

• Gyo (凝, "concentration") - strengthening the aura on a specific part of the body (for example, on the eyes, in order to see someone else's aura).

• Shu (周, "coverage") - spreading the effect of Gyo to an object in the hands to strengthen a weapon or tool.

• Ken (堅, "strength") - uniform strengthening of the entire body surface for defense and attack.

• Ryu (流, "flow") - dynamic redistribution of strengthening zones between attack and defense.

Key concepts

• Shoko is the “gate” of the aura: one must learn to consciously open and close them in order to control the flow of Nen.

• MUN (Max Ora Portion) - the maximum volume of aura that the user is able to generate.

• RUN (Potential Ora Portion) is the real limit of one-time emission of aura.

Considering you were previously interested in Nen, Kurapika, and his Chain of Justice, it's worth noting: The Chain of Justice is a manifestation of the Hatsu-type "Materialization", and its special effects (such as instant death for members of the "Spiders")

Basic Nen Techniques (4 Main)

• Ten (纏, "to envelop") – holds the aura within the body, preventing it from dissipating. This is basic defense and the foundation for other techniques.

• Zetsu (絕, "to cease") - completely stops the emission of aura. Useful for hiding from Nen sensors and conserving strength, but makes the user vulnerable.

• Ren (練, "to train/strengthen") – dramatically increases the production of aura around the body. Grants great physical strength and strong defense, but requires control, otherwise one can quickly become exhausted.

• Hatsu (發, "to release") is the individual application of aura: it is through Hatsu that the unique abilities of characters are created.

Types of Hatsu (6 categories)

Hatsu type is determined using the "glass of water and leaf test." It reveals the user's natural inclination:

• Enhancement (Kyoka) - increases physical parameters: striking power, speed, regeneration. Example: Gon Freecss.

• Transformation (Hank) - changes the properties of the aura (turns it into electricity, makes it sticky, etc.). Example: Killua Zoldyck (electricity), Hisoka (elastic/sticky aura).

• Emission (Hoshu) - allows one to separate aura from the body and use it remotely. Example: Illumi Zoldyck.

• Manipulation (Sosa) – control over objects and living beings. Example: Shalnark (Nen-phone).

• Materialization (Genjutsu) - the creation of physical objects from aura. Example: Kurapika (Chain of Judgment).

• Specialization (Tokushin) - unique abilities that don't fit into other categories. Example: Kuroro Lucifer (ability theft).

How is the test performed?

A glass of water is placed in front of the subject, and a piece of paper is placed on it. The subject should inject a small amount of their aura (Nen) into this structure—without any complicated techniques, simply gently directing the flow. The reaction of the system (water and paper) reveals the Hatsu type.

What do the different reactions mean?

Water overflows → "Enhancement" type. The user has a natural ability to enhance physical attributes (strength, speed, regeneration). Example: Gon Freecss.

The taste of water changes → "Transformation" type. A person can change the properties of their aura (turn it into electricity, make it sticky, etc.). Example: Killua (electricity), Hisoka (elastic aura).

The color of the water changes → "Extraction" type. The ability to separate aura from the body and use it remotely. Example: Illumi Zoldyck.

The leaf moves → Manipulation type. Control over objects and living beings. Example: Shalnark with the Nen Phone.

The water becomes cloudy and dust particles appear in it → "Materialization" type. Creates physical objects from aura. Example: Kurapika and his "Chain of Judgment."

Any other effect that doesn't fit into the previous categories → "Specialization" type. Unique abilities that don't fit into standard types. Examples: Kuroro Lucifer (ability theft), Neon Nostrade (divination). Nen (念) is a system for manipulating aura (life energy) in the Hunter × Hunter world. It is the core combat mechanic of the universe: virtually all serious fighters use Nen in some way, and for Hunters, mastering Nen is a must.

Instilling a sense of danger. Illumi could methodically show Diana that her friends are vulnerable: "They will force you to take risks. They don't understand who you're connected to, and they will die because of it." He presents this not as a threat, but as a cold truth that must be accepted.
A guilt trip. He could have been implying that Diana's attachment to her friends made her weak and put her family at risk: "As long as you're thinking about them, you can't be reliable. You're letting down those who raised you."
Creating a false choice. Illumi knows how to frame the situation so that Diana's "independent" decision is exactly what he wanted. For example, he might offer, "Choose: either you keep your distance from them, or I'll make sure they don't bother you anymore." In this formulation, either choice leads to his control.
The use of needles and mental control. In canon, Illumi marks someone with needles, which can suppress their will or cause pain if they disobey. In the context of friendship, this could be seen as setting a condition: "If you get too close to any of them, you will suffer the consequences." This literally limits their social circle.
Subverting the concept of "true intimacy." Illumi conveys that the only secure bond is family, and that friendship is temporary and unreliable. He can devalue Diana's friends, exposing their weaknesses and mistakes, so that she begins to doubt them.
A show of force as an argument. He may deliberately create situations where Diana's friends appear helpless and he appears to be the only one capable of fixing everything. This undermines Diana's trust in her friends and increases her dependence on him.
Control through "care." Illumi disguises pressure as care: "I'm doing this so you survive." This way, he prevents Diana from perceiving his actions as violence, presenting them as necessary protection.

Appearance
Illumi is a tall, lean young man with long, jet-black hair, usually slicked back, and large, dark, pupil-less eyes. His face is practically expressionless—no matter what emotion he's experiencing, the most that changes is a widening of his eyes.

He wears unique costumes that allow him to move freely. To modify his body, Illumi uses large, round-headed pins. With them, he can change not only his facial features but also his voice. Without the pins, he can maintain the transformation for about five hours, while his eyes remain unchanged.

Character
Illumi is a complex and contradictory character. He is vain, arrogant, cold-blooded, and ruthless. His moral values ​​are skewed toward his own ambitions, his family's interests, and the whims of the moment. He has no regard for human life, killing even those who trust him on a whim.

At the same time, he has a peculiar sense of duty: he respects his father Silva, reveres his mother Kikyo, and cares for Killua. However, his concern for his brother takes a terrifying form: to ensure his obedience and survival, Illumi implanted a special needle containing Nen into Killua's brain. It activates his brother's survival instinct, causing him to flee from battles in which victory is uncertain.

(Illumi: When he plans a murder or goes into a violent manipulation mode, his eyes narrow and sharpen, becoming more "prickly." This emphasizes his focus, cold calculation, and readiness for action.

When he attempts to hypnotize or seriously intimidate, spiral patterns appear in his eyes. This design enhances the sense of hypnosis: it seems as if his gaze literally paralyzes or subjugates. Illumi implanted such a needle in his younger brother Killua's brain to prevent him from engaging in battles he wasn't sure of winning. Resisting the command is difficult: the victim experiences a growing headache, which helps locate the needle.
Needles for creating "Needle Men" (Hariningen). They have a thinner, longer shaft with a spherical yellow handle. When pierced through the skull, one of these needles causes the victim to lose their mind and become Illumi's obedient "puppet." He can issue orders, and the victim will carry them out, even at the cost of their life or until they are completely exhausted. If the victim survives this procedure, they will be crippled for life. Interestingly, Illumi can also control corpses: by piercing the head with several needles, he forces the dead body to perform actions, such as talking or driving.
Illumi accurately throws multiple needles at once and can combine them in combat. Illumi openly disdains Killua's desire for a normal life and friendship, convincing his younger brother that he doesn't need friends because he's a killer by nature. This direct clash of values ​​and worldviews intensifies Killua's internal conflict and his fear of not living up to his brother's expectations.
