Izunavi

Izunavi (イズナビ, Izunabi) is a Hunter and Kurapika's Nen master.

Appearance
Izunavi is a shaggy man who is always seen wearing a keikogi and two-heeled geta (sandals). He is sometimes seen carrying a duffel bag behind him. As a Royal Bodyguard he dresses in a black suit and tie just like the other bodyguards. On the top left of his suit is a capital H.

Given that Tyson prefers handsome men as her bodyguards, it is safe to assume that Izunavi is good-looking.

Heaven's Arena arc


In the 2011 anime adaption Izunavi (Mizuken) first encounters Kurapika in a ghost town near the Sengi Guild and steals his Hunter License. Later after a confrontation between Izunavi and Kurapika the two fight it out with each other only for Kurapika to be handily beaten by his opponent. Izunavi comments that Kurapika has no chance of beating him while Kurapika distraught from losing the fight, says he wants the power to fight with his own power. Impressed by Kurapika's gumption, Izunavi returns Kurapika's Hunter License to him and offers to train him.

Yorknew City arc
Izunavi has Kurapika take the Water Divination test to find out he's a Conjurer. Kurapika laments this wishing he was an Enhancer. Izunavi explains to Kurapika he can still learn Enhancer and other Hatsu techniques to a certain percentage. When inquired why Specialization is 0%, he explains that it's a trait you develop as you age or inherit, but Kurapika has a good chance of becoming one.

Izunavi goes onto explain if Kurapika was to fully master his Nen category and was to face off against an Enhancer who has also fully mastered his respective category, his chance of victory would be slim. This is due to Enhancers natural efficiency with Offense, Defense, and Recovery and since Kurapika can only defend himself against Enhancer moves by 60%. Though using Nen in combat makes it more complex, there's also the fact that all emotions factor into Nen that could enable you to surpass the 100% limit. But that's taking a risk going over the 100% factor, which could cause strains and can create a fatal weakness, so fighting with consistent power is sufficient.

Curious, Kurapika inquires if there's a chance to win against a Master Enhancer as a Conjurer if he fights in a consistent fashion. Izunavi answers that Conjurers aren't as balanced as Enhancers in offensive and defensive capabilities, however if he was to find his niche he would be formidable and quizzes Kurapika with, "Can a Conjurer materialize a sword that can cut anything?" Kurapika answers No, because it's beyond human capabilities. Izunavi confirms it, going onto say that even master Conjurers can't materialize practically anything. He goes on explaining, while you it's possible to conjure a sword it's better to purchase your own, but conjured swords can appear and disappear at the users will.

Izunavi advises Kurapika to consider carefully, what he wishes to conjure. After a brief contemplation, Kurapika chooses chains and his reason is he desires to drag certain people to hell. Unimpressed by Kurapika's choice claims he's the one that's bound. This irritates Kurapika causing him to storm off as Izunavi tries to explain that conjuring regular chains is pointless, for they can't be unbreakable. Still ignorant to Izunavi's explanation, he details that while impossible to conjure unbreakable chains, there's a way to materialize something close to it. Intrigued Kurapika asks for more information, annoying Izunavi for only listening to things that benefit him.

Izunavi then explains that Kurapika must make a contract with himself in which he makes conditions, swears to abide them and the stricter the limitation, the greater power gained. So in order for Kurapika to conjure unbreakable chains, he'd have to impose strict condition on himself, but warns him of the dangers it could occur on him. Kurapika vows to only use his chains on the ones who stole his brethren eyes and wagers his life on it. With that last comment Kurapika's eyes turn scarlet and Izunavi notices that his Nen aura spiked and has him retake the test to find out that when his eyes turn scarlet he becomes a Specialist.

Greed Island arc
Izunavi was indirectly mentioned by Kurapika when he explains to Gon how Izunavi taught him the detailed process to fully master conjuring chains.

13th Hunter Chairman Election arc


After the death of Chairman Netero, Izunavi appears at the Hunter Association to vote in the First Election for the 13th Hunter Chairman.

Succession Contest arc
Kurapika recruits Izunavi to be hired as a Kakin prince's bodyguard, with the mission being to get information regarding Prince Tserriednich. He is the penultimate one to accept a job request and is hired by Prince Tyson. In a flashback, when Izunavi was still teaching Kurapika Nen. He advises him to focus on co-operation with allies. When Prince Tyson finally learns about the existence of the Guardian Spirit Beast, she initially thinks hers resembles an angel. Izunavi, being able to see the Guardian Spirit Beast and in order to please her, tells the prince that hers looks more like a fairy, which delights Tyson.

Later Izunavi receives a book titled "Book of Tyson", containing teachings by Tyson. Izunavi and another bodyguard reads the first chapter and Izunavi instantly becomes disgusted by it, although he praises Tyson for being so happy go lucky at such a critical time. The other bodyguard offers to teach him how to praise someone for a book he's never read. When Tyson asks them if they liked her book, Izunavi is impressed by the bodyguard's ability to lie. He simply confesses he has not read it yet. The two bodyguards reflect on the meaning of the Nen beasts on their shoulders. The other bodyguard advances they might be a sign they were accepted by the Sixth Prince. Izunavi is more cautious and lashes at his colleague for being too carefree.

The next morning, the Sixth Prince begins to preach, and an unconvinced Izunavi applauds her. The other Nen-using bodyguard recognizes her words as being the same as the lyrics of a Khana Nishina song, who Izunavi does not know. The two comment that they don't feel anything sinister from Tyson's Nen beasts. The other bodyguard reckons that it is unlikely someone who preaches about love has a harmful Nen ability, and suggests they might serve to gather aura with a reference to the manga DB, which Izunavi has read.

Abilities & Powers
Izunavi has all the benefits granted by his status as a Hunter. He is a capable teacher, allowing Kurapika to grow to the point he is capable of fighting and killing members of the infamous Phantom Troupe.

Nen
The only demonstration of his abilities with Nen was given when he threw an aura-imbued acorn at Kurapika, which, in spite of the fact that he was reducing its speed to allow Kurapika to dodge, was still several times more powerful than a bullet, completely destroying part of a tree trunk.
