Nanika (ナニカ, Nanika) is a mysterious Dark Continent creature who came to possess Alluka Zoldyck under unknown circumstances. The two currently coexist inside Alluka's body.


Nanika's real appearance is unknown. When it manifests itself, it tinges Alluka's sclerae, irises and mouth pitch black, also causing the latter to appear larger.

Nanika cries

Like Alluka, Nanika is very fond of Killua Zoldyck, whom it fondly calls by name ("Big brother" in the Viz translation). Nanika strives to earn people's praise and especially Killua's by granting wishes, and usually asks him to pet it. When Killua orders it never to appear any longer, Nanika becomes hurt and cries. It later forgives Killua, after Killua promises to protect both Alluka and Nanika and to pet Nanika whenever it wished. Nanika also appears to be on good terms with Alluka, as the latter was very upset when she felt its misery.[1]

Nanika's way of speaking is extremely concise.


It is unknown when and how Nanika came to possess Alluka, but the two have shared the latter's body at least since Alluka was a young child. The Zoldyck Family is in the dark about Nanika's nature. Killua once saw Alluka turn into Nanika, and learned about the general nature of its abilities by asking it how to revert the transformation. 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 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.[2]


Alluka in wish granting mode as a toddler

To test the ability, her mother Kikyo Zoldyck 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.[2]

Some time afterwards, Yasuha, another female servant of the Zoldyck family, after granting two other wishes, 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. Nanika 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.[2]

Illumi Zoldyck became interested in Alluka's power and asked for Silva Zoldyck'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, suddenly afraid, declined. She followed up with three continuous requests for her duodenum, spine and brain respectively, which were all declined as well. 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. 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 Nanika granted a large wish.[2] Following the blimp incident, Nanika's power caused the death of six couples, for a total of twelve more people: two were necessary for Kikyo to be convinced, two more to test the rules, and two when Milluki Zoldyck sacrificed tourists in exchange for cheap toys. At some point, there was also another big incident which resulted in the death of 13 people, caused again by Milluki, who asked Nanika to kill his target for him. Milluki had a tourist named Muna pay the price by telling him to just ignore Alluka's requests.[3] More recently, Milluki used Nanika to get the latest—at the time—computer.[2]


13th Hunter Chairman Election arcEdit

Nanika is brought into the story when Killua wants to heal Gon. Killua goes into his home and requests to see Alluka. When Silva agrees, they go to Alluka's isolation room filled with stuffed animals and other toys. After they are reunited, Alluka asks Killua to "die" for her, play shiritori, and pat her head. Finally, she turns into Nanika. Killua asks her to kill his mother if they don't make it out of the home in time or to kiss him on the cheek if they do. Nanika's next appearence was after requesting and receiving some of Tsubone's nails. It is asked to heal Tsubone by Killua. Nanika's last appearance was when they reached the hospital where Gon was. Killua asks Nanika to heal Gon, which she does by touching his hand. Killua tells Nanika to not come out again after considering what would be best for Alluka. At first, Nanika doesn't understand and simply tells Killua that she loves him. When Killua yells at her, Nanika starts to cry. Killua thinks it is the best choice, only to be comfronted by Alluka. Killua apologizes to Nanika.[citation needed]

Abilities & PowersEdit

Nanika has the ability to attach itself to another living being and coexist within their body, taking control of them when certain conditions are met. Its physical abilities are dependent upon those of the body it inhabits. Currently, it has the strength of a normal child.[4] Alluka shares an empathic link with Nanika, which allows her to perceive its emotions.[1]


Nanika's power is speculated to be infinite.[3] Since it releases aura, it appears to be a Nen ability. Illumi and some of the Zodiacs were deeply impressed with the immense amount of aura it could output.[5] It is unclear if Nanika retained its ability to grant wishes after Killua told it to stop doing so.[1]

Nanika's Abilities
Wish Granting
Nanika - 145

138 - Declining Alluka's requests

After a person fulfills three of Alluka's requests Nanika will assume control over Alluka’s body and grant one wish. 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 as long as it was declared during Nanika's appearance. According to Killua, the degree of wish that Nanika can grant is probably infinite, going from briefly levitating a person into the air to altering probability and reality to make any effect occur. Nanika is capable of effortlessly teleporting someone to another continent and is also able to lift Gon's vow and heal his mangled body. However, the greater the wish made to Nanika is, the greater the next three requests will become. The one that must bear the burden of the next three requests is not the one that Nanika granted the wish to; it is the next person that Alluka makes requests to. If that person declines or fails to fulfill Alluka's requests four times, at least two people will die with an increasing amount of casualties correlated to the scale of the previous wish, all deaths occur instantly and simultaneously; firstly, the request recipient and their most loved one will die from being crushed by an invisible force, and any additional deaths are chosen based on persons who spent the most time with the request recipient, regardless of their relationship to them. Unlike the recipient, they are wrung to death instead of crushed. One example is when Kasuga, a servant of the Zoldyck family, failed to fulfill Alluka’s requests four times, the cost of the billion Jenny wish made previously by another servant, Yasuha, was transferred to her, and thus she, her lover, and 65 people that had spent the most time with her throughout her life were killed.

There are five rules about Nanika's power known by the Zoldyck family as a whole from their trial and error experiments as the expense of their butlers, 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 one wish at a time, Nanika can be given several conditions to a single 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. Furthermore, there isn't any sort of cruel backlash, although this may be a rule Killua made up to hide his special privileges. It is also shown that healing is very taxing to Nanika, causing Alluka to fall asleep from exhaustion.
  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.


  • (Upon granting wishes) "'Kay."
  • (To Killua Zoldyck) "Brother, pet me!"[1]
  • (To Killua Zoldyck) "I love you, brother!"[1]


  • There is no conclusive evidence or explicit confirmation in the manga nor from the mangaka, Yoshihiro Togashi himself, that Nanika is one of the creatures from the Dark Continent. This idea, however, came from the explanation about one of the Five Great Calamities (specifically the "Ai") and the fact that one of the Zoldyck family members, Zzigg Zoldyck, came with Chairman Netero when they explored the Dark Continent.
  • "Nanika" literally means "something" in Japanese, which is Nanika's name in the Viz translation.
  • 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.
Vol 33 Extras (Nanika)

Nanika in Vol. 33 extras

  • Throughout the story, many hints are scattered suggesting the possibility of Nanika being an Ai:
    • As revealed in Volume 33, both originated in the Dark Continent.
    • Nanika's victims are either squashed[2] or wrung to death[3] if her requests are refused; some of the ascertained victims of the Five Great Calamities were killed exactly that way. It was also stated that, although their manner of death was described in Journey to the New World, those bodies were all found in the known world rather than in the Dark Continent, and that the massacre is ongoing.[6] Ging Freecss has also revealed that victims of Ai and Pap have been found in the known world.[7]
    • Nanika has a peculiar way of saying "yes" (translated as "'Kay" by Viz) in the original: instead of "hai" (はい), she pronounces it "ai" (あい). When written in katakana (アイ), this is the name of one of the Five Great Calamities, Ai, as well as its distinctive call (in hiragana again).[6]
    • Nanika has the same deep black eyes as Ai. Furthermore, in the extras, Alluka's skin, while possessed, is colored black with the same technique used to draw Ai.[6]
    • Nanika's possession of Alluka, her wish to please others and her devotion to Killua could be related to Ai's description as "codependence of desire".[6]
