Alluka Zoldyck (アルカ=ゾルディック, Aruka Zorudikku) is the second youngest child of Silva and Kikyo Zoldyck.



Alluka as a toddler

Alluka has long black hair, blue eyes, and pale complexion. She wears the traditional clothes of a Japanese shrine maiden, with boots and a headband adorned with emotional cartoon faces. Framing her face are two locks of hair, each fastened by four hair bands decorated with the same cartoon faces on her headband.

As a toddler, Alluka had shoulder length, slightly messy hair and wore pants.

Gender Ambiguity

There is conflicting information regarding Alluka's gender.  

The official data book lists Alluka's sex as male, and two of Alluka's brothers, Illumi and Milluki, refer to Alluka as their brother.[2] In flashbacks, Zoldyck servants call Alluka "bocchan" or "bocchama." Morel once referred to Alluka as Killua's brother, and Killua did not correct him.[3] However, due to most of the Zoldyck's isolation from and fear of Alluka, along with their viewpoint that Alluka is a "thing" and not a member of a the family, their referring to Alluka as male may be part of deliberate abuse.

Killua has an intimate and understanding bond with Alluka. When Killua introduced Alluka to Gon, he introduced Alluka as his sister.[4] Previously, he had stated that Alluka being a girl was the reason they needed female butlers to attend to Alluka on their mission to save Gon.[5] Killua refers to Alluka as his sister multiple times, including when they were children.[6]

This article uses the feminine pronouns she/her to describe Alluka because Killua, who is more compassionate toward Alluka than any other member of their household, insists that Alluka is a girl and his sister.


Before Alluka was formally introduced in the manga, Silva refers to Alluka as a dark and uncontrollable child. He claims that Alluka has no soul because of the circumstances of her birth, and cannot feel emotions.

However, once reunited with her closest brother Killua, Alluka acts like a child with loving and lovable personality. She displays a rather simplistic and childlike personality, contrasting with Killua's mature composure. She often acts very happy with Killua, likely because he was the only one to show any compassion towards Alluka, and trusts him deeply. This implies Alluka has a compassionate personality, contrasting with her potentially horrific ability.

According to Killua, Alluka calls him "Big brother", while Nanika calls him only by name.

Alluka's first appearance is in a family photo of the Zoldyck siblings and their mother. It was first shown in an earlier Chimera Ant arc chapter illustrating Kalluto's desire to get his older brother back no matter how many years it will take. In the photo, Alluka was not posing together with the rest of the family, instead she was standing at a distance behind them and facing away. Her name was not revealed in the manga until chapter 321, and for a long period of time readers of Hunter × Hunter could only guess the name of the facing-away child based on the information about the Zoldyck family provided in the 2004 official data book.

Alluka officially makes a debut appearance in the manga in chapter 321 in which she is seen sitting unemotionally on the floor of a room full of dolls. Silva, when talking to Killua about Alluka, refers to her as an 'it' and says she is darkness.

Through Killua's flashback of his childhood,[6] some background information about Alluka is revealed. As a toddler, Alluka once asked Mitsuba, an attendant of the Zoldyck family, to do three simple things: carrying her, going up a staircase, and raising Alluka up in the air. After Mitsuba did what she was told, Alluka's eyes and mouth suddenly turned pitch-black. Freaked out by this, Mitsuba called for help. Killua came and changed Alluka back to normal by asking Alluka to make himself (Killua) go high-high, which Alluka did. After the accident, Killua had to tell his parents about Alluka's secret because Mitsuba had already reported it to them. It turned out that when Alluka had three requests fulfilled, her eyes and mouth would turn pitch-black, and they would change back to normal only when she heard and granted a wish.


Alluka in wish granting mode as a toddler

To test the ability, her mother Kikyo ordered Mitsuba to decline any request of her, no matter how small it was. Due to that, Mitsuba and her lover Hasama, who was not around Alluka at that time, were mysteriously crushed into minced meat simultaneously. Killua explained that this was the consequence of saying 'No' to Alluka's requests 4 times.

Some time afterwards, Yasuha, another female servant of the Zoldyck family, gave Alluka a piggyback ride at her request, thus activating wish-granting mode. Giving in to her greed at the time, Yasuha wished that Alluka would make her a billionaire. She agreed and suddenly a large amount of banknotes started to rain down from a blimp in the sky. It was later reported that a currency transport vessel had suddenly gone missing and by the time it had been found all the money had disappeared, and the captain and crew kept giving nonsensical answers.

Illumi became interested in Alluka's power and asked for Silva's permission to deal with Kasuga, the next servant, to take care of Alluka, in his own way. He told her to listen to Alluka's requests in exchange for his tolerance of her romantic relationship with an outsider to the Zoldyck family. When Kasuga was with Alluka, Alluka suddenly asked her for her liver, which Kasuga declined. She followed up with three continuous requests for her duodenum, spine and brain respectively, which were all declined as well.[7] As a result of Kasuga's refusal to fulfill those four requests, a total of 67 people, including herself, were killed at the same time by Alluka's strange power.[3] This occurrence revealed that her ability had a cumulative effect; the greater the previous wish was (in terms of fulfillment difficulty), the greater the consequences of refusing her next set of requests. From this, they also learned the requests became much more difficult to fulfill after Alluka granted a large wish.

Killua and Alluka meet again

Alluka is formally introduced when Killua came back home to Kukuroo Mountain to see his younger sister. He asks for his father's permission but Silva disagrees, thinking that it's too dangerous despite the fact that Killua knows Alluka better than anyone else in their family.[6] After a long talk, his father takes him to Alluka's room, hidden behind a series of five big safety vaults, each of which can only be opened after entering a 10-digit password.[7] Alluka excitedly greets Killua when he entered the room, calling him "Big brother". She first wished for Killua to "die" for her. Next she wanted to play Shiritori[3] and lastly, have Killua pat her on the head.

Through a surveillance camera, Silva, Kikyo and Milluki watch the whole scene. Kikyo is delighted in Killua's actions, while Milluki regrets wishing for a PC which made Alluka's wishes on Killua so easy. This earns him a glare from his father. Silva then asks about the rules regarding Alluka's power. When Killua decides to take Alluka with him, Silva disapproves and insists that the wish shall be made inside the room. Killua wishes to Alluka that if they are not able to leave the mountain together within 30 minutes, their mother will be killed. If they are, then she will give Killua a kiss on the cheek. Silva lets them leave, but orders a few butlers to accompany them, including Gotoh, Canary, Tsubone and Amane.[5]

As they make their way to the hospital where Gon is, a truck whose drivers were being manipulated by Illumi crashes their car. Killua protects Alluka; according to the restriction rules that their father laid down, if Killua stays at least one meter away from Alluka, they will be taken home instantly. As Illumi and Hisoka watch from afar, the assassin asks the latter to eliminate the butlers, or if possible, take Alluka away from Killua. Using his Godspeed ability, Killua escapes their butlers with ease but Tsubone follows them.[8]

Killua and Alluka continue to escape and are still followed by Tsubone.[9] Killua tries to escape faster but Tsubone uses her ability that can catch up to Kanmuru's speed. The two Zoldycks reach the airport and rides in an airship to further escape Illumi. Alluka is seen sleeping inside while Killua drives the airship himself. He explains to Morel about Alluka's wish-granting ability, which Morel thinks as a vaguely terrifying ability.[10]

When the airship they were riding on finally landed Killua made arrangements to continue their escape by car, only to find themselves surrounded by Illumi and his Needlemen. There, he asks for Alluka to be handed to him while Killua straightly refuses. In the middle, Tsubone appears and reveals that it is her fault that they are tailed through a hidden camera that is being fed to their Kikyo and Milluki, where the latter, in turn, is sending the information to Illumi's phone. After seeing Tsubone, Alluka's request-mode commences again where she asks for the nails from Tsubone's middle and ring finger, completing the three requests entering to the wish-granting state. Instead of using the wish to get out of the predicament they arein, Killua uses the wish to heal Tsubone's hand to demonstrate and reveal to Illumi some rules that he only knows.[11]

Alluka about to heal Gon

Finally, Alluka wakes in Gon's hospital room. Killua asks his sibling to turn into Nanika, but Alluka refuses, wanting to stay with Killua. When Killua begs her, she eventually gives in and changes into Nanika. Killua asks for Nanika to heal Gon, and Nanika complies and touches Gon's hand. As Nanika is healing Gon, a huge energy comes from the latter, which is so powerful that Hunters in the Hunters Association building felt it.[12] Alluka successfully heals Gon and falls asleep.[13]

Illumi tells Killua that if he can have control over Alluka like Killua does, he will guarantee minimum freedom for Alluka. However, Killua wakes Nanika and orders her to send Illumi home, which Nanika does and Illumi finds himself instantly teleported back to the Zoldyck mansion. Due to Killua's request, Amane and Tsubone leave the room to give the siblings privacy. Killua tells Nanika that she can't come out anymore. Nanika disagrees and is clearly upset by Killua saying how much she likes Killua. After a brief argument which leads Killua to yell at her, she becomes upset but complies, going back inside. Alluka wakes up and is angered by what Killua said to Nanika. She yells at Killua, saying that he needs to protect both Alluka and Nanika, and that Alluka would hate any brother who was mean to Nanika. Killua realizes his mistake and asks Alluka to bring Nanika out so he could apologize. Nanika reappears teary and upset from the previous confrontation.[1]

Not long after, Alluka and Killua accompany Gon on his trip to the World Tree. Then, they say their goodbyes and part ways with Gon.[4]

Abilities & Powers

Illumi states that unlike the other children of the Zoldyck family who were trained from a very young age to possess abilities like high resistance to poisons and electricity and great physical strength, Alluka has no combat abilities at all, and she is just like a normal kid when it comes to fighting.[3] All of the powers attributed to Alluka on this page are in fact Nanika's powers.


Nanika's powers are known to operate using aura.[14]

138 - Declining Alluka's requests

Alluka is considered to have no soul or emotions by the Zoldyck family with the exception of Killua, and will grant one wish after a person fulfills three of Alluka's requests. After the requests have been completed, Alluka's eyes and mouth darken to black and Alluka transforms into a dark continent creature named Nanika. The wish doesn't have to come from the one who fulfilled Alluka's requests, as even an extra party can have their wish granted for as long as it was declared in Nanika's presence, who would usually state "Aye" as confirmation that the request made was granted. According to Killua, the degree of wish that Nanika can grant is probably infinite, going from briefly levitating a person into the air, to affecting probability to make a certain effect occur. However, the greater the wish made to Alluka is, the greater the next three requests will become. The one that must bear the cost of the next three requests is not the one Alluka granted the wish to; it is the next person who must do it. And if that next person declines to fulfill Alluka's requests four times, depending on the difficulty level of the previous wish, at least two people, he and his most loved one, will die. The other people who die, along with the recipient of the requests and the recipient's most loved, are in order of who the recipient spent the most time with regardless of whether or not the recipient loved that person. One example is when Kasuga, a servant of the Zoldyck family, declined Alluka's four requests, the cost of the billionaire wish made previously by Yasuha was transferred to her, and thus she, her lover, and 65 other people were crushed to death.

There are five rules about Nanika's power known by the Zoldyck family as a whole, but Killua is aware of some others by himself. Below are the rules known by the family:

  1. If someone fails to fulfill Alluka's requests and gets killed, the difficulty level of Alluka's requests returns to level 1. That is the best time to make a wish.
  2. If Alluka is making requests from a particular person, they cannot be moved over to another person mid-way. Therefore if that particular person disappears such as concealing themselves, Alluka is unable to make requests to anybody else.
  3. If the person fulfilling requests dies mid-way, it will count as a failure and at least one more person will die.
  4. Alluka cannot make requests of someone without knowing the person's name.
  5. The same person cannot ask Alluka for consecutive wishes, although Killua seems to know of a way to bypass this condition.

Rules known only by Killua:

  1. While Nanika can grant only 1 wish at a time, one can give Nanika several conditions to a wish, therefore greatly expanding the capacities of what one can ask of Nanika before granting another 3 requests.
  2. If a wish is made for healing, Nanika must make physical contact with the target; there isn't any sort of cruel backlash as well. This may simply be a rule Killua made up due to his special privilege.
  3. Killua, due to his relationship with Alluka and Nanika, is given special privileges. When he "commands" Alluka, Alluka's request will bypass any existing backlash and will be granted without any repercussions. If somebody else wishes other than Killua, they will suffer the same repercussions of the previous wish that was supposed to be given. This privilege has been deduced by Illumi, adding to his craving to control Killua in order to control Alluka's abilities.

Zoldyck Family

  • In the 2011 version, Alluka appeared in a silhouette of the Zoldyck family members, alongside the Zoldyck's unnamed grandmother who is yet to appear in the manga or anime. In the silhouette, Alluka can be seen holding Killua's hand.
  • "Nanika" literally means "Something" in Japanese.
  • Alluka share some similarities with Yukina from Yu Yu Hakusho as both are the younger siblings who shares a close relationship to their brothers, Killua and Hiei respectively.
  • The Viz translation of the manga reverses the way Alluka and Nanika refer to Killua. In the English version of the manga, Alluka calls Killua by name while Nanika calls him "big brother". The reason for this change in translation is unknown.
