Heavens Arena arc

Kurapika defeated by mizuken

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.[2]

Yorknew City arc

Izunavi has Kurapika take the water divination test to find out he's a Conjurer. Although Kurapika admits he wanted to be an Enhancer, Izunavi explains it's still possible for him to learn Enhancer techniques. With the help of a hexagon chart Izunavi details if his aptitude for Conjuration is 100% then the maximum level of mastering the other aspects would be Transmutation 80%, Manipulation 60%, Enhancement 60%, Emission 40%, and Specialization 0%. He then explains that the farther away from an aspect the less you can master it. Kurapika then inquires why Specialization is 0% and Izunavi explains it's because it's an aspect that can't be learned, but rather it's a trait you grow up with or inherit. However Kurapika has a good chance of one day becoming one, due it being on the bottom of the chart.[1]

Izunavi reminds Kurapika what he once told him he wants the power to be able to fight completely independent. Naturally an Enhancer would be ideal for its efficiency in Offense, Defense, and Recovery. However he'd only be able to master a little more than half the Enhancer abilities. Izunavi then gives Kurapika an example if he was an Enhancer and fully mastered his ability and faced an Enhancer who also fully mastered his own ability. Izunavi then preforms Ko and explains if he took a fully enforced punch from his opponent then it would measure up in the following equation: Flesh Punch 100 + Nen enhancement 100 = 200. But since Kurapika is a Conjurer, it would be the following equation: Attack Points 100 + Sens Points 60 = 160 in other words: Attack Points 100 - Sens Points 60 = 40. Making Kurapika's chance of winning against an Enhancer quite slim, but that's only from a simplified calculation.[1]

Because no single person has equal strength and how various conditions make up how you fight, Nen makes it more complex. Since all emotions factor into Nen, it may enable something to surpass the 100% limit, which isn't suggested even in combat. Preforming such an act causes strain and could create a fatal weakness, so fighting with consistent power is best. Kurapika then asks if being consistent as a Conjurer would he able to win against a master Enhancer? Perplexed by the question 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. Izunavi then questions Kurapika, "Can a Conjurer create a sword that can cut anything?" Kurapika responds No, because it goes beyond human capabilities. Izunavi confirms it, because there are things you can't create even if you're a master Conjurer.[1]

It's possible to Conjure a regular sword, it'd be better if you were to purchase your own, however regular swords can't disappear on command like a conjured one. It's pointless to conjure something that's already exists, but you can't conjure something that's something over unnaturally specific, making it difficult for a Conjurer to be combative. So Izunavi explains to Kurapika should carefully consider what exactly he wishes to conjure and Kurapika decides on Chains. Not only it was the first thing that came into his mind when he found out he was a Conjurer, but because he has people drag into hell. Contemplating over it Izunavi speculates he's the one that's bound, which agitates him and walks off. Izunavi tries to stop him, explaining that conjuring a regular chain is pointless and creating an unbreakable one is impossible. Kurapika still however doesn't listen so Izunavi confesses there's a way to create one close to it, with self-imposed limitations.[1]

Izunavi further explains that Kurapika must make a contract with himself in which he makes conditions and swears to abide them. And the stricter the limitation, the more power would be gained. With self-imposed limitations put into the equation, would measure: Attack Points + Sens Points x Mystery Points = !!. In order for Kurapika to be able to conjure an unbreakable chain he'll have to create strict conditions for himself, but Izunavi warns Kurapika that it's a double edged sword and could fatally backfire against him. Kurapika's conditions are he'll only use his chains to capture his targets and find the eyes of his brethren and the chains will always be used on his targets and the chains won't let them escape. Izunavi comments how limited and fixed the condition is, however Kurapika further explains if he breaks his condition he'll sacrifice his life, while his eyes turn scarlet.Amazed by this Izunavi has Kurapika retake the divination test, to discover he's Specialist when his eyes are scarlet.[1]

Izunavi was indirectly mentioned by Kurapika when he explains to Gon how Izunavi taught Kurapika the detailed process he had to undergo to fully master conjuring chains.[3]

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.[2]
