Kurapika captures Uvogin with his chains and they quickly run away. Leaving him in hands of Dalzollene, the leader of Neon's bodyguards, Kurapika leaves to meet with Hisoka who promises to give some information on other members of the Phantom Troupe. Dalzollene asks people from mafia community to come to pick up, but instead Phantom Troupe members arrive, killing him and freeing Uvogin. Leorio shows Gon and Killua his Ten and it turns out to be the only Nen technique he is aware of.

Mafia people attack the Phantom Troupe, but in vain: they are not Nen users, and Uvogin is able to catch a bullet with his teeth and withstand a point blank shot from a bazooka. Four members of the Shadow Beasts arrive, they are noticeably stronger than Kurapika companions, but even they are defeated by just one Phantom Troupe member.

Chrollo Lucilfer, the boss of the Phantom Troupe, gives them orders to go to the underground auction and kill everyone there, and they proceed. Franklin uses a machine gun hidden in his fingers to fire Nen bullets, and Shizuku cleans up so that no traces of the massacre are left visible. Melody and Kurapika are talking more openly to each other while waiting on the roof. The mafia community sends the group of its best fighters called Shadow Beasts to deal with the Phantom Troupe.

Neon with all her bodyguards arrives at Yorknew. Her Nen ability is shown: Lovely Ghost Writer that predicts the future. Four members of the Phantom Troupe are shown walking to Yorknew: Feitan, Machi, Franklin, and Nobunaga. The last two are having a quarrel. Gon wants to buy a mobile phone and is unexpectedly helped by an old friend, Leorio. Later he also helps to raise funds by allowing people to pay for arm wrestling with Gon who easily beats everyone and has some trouble defeating Shizuku.

Gon and Killua leave Mito and her mother to go to Yorknew. They got even more information about Greed Island from a website available only for hunters. They need a lot of money to buy it, even millions they earned at Heavens Arena are not enough. They try to earn more by getting bargains on-line, but fail miserably, cutting their funds to 10 million jenny. Milluki, Killua's brother, could not decode the game from the card data and goes to Yorknew to buy it too. Hisoka is also showing flying there. After all tests Kurapika got his job and is introduced to his boss who turns out to be a teenager named Neon Nostrade.

Gon and Killua order a Joystation and see that the card they have contains data for Greed Island game that cannot be found on Internet. Killua calls his brother who is a devoted gamer, but even he doesn't have that one (however, he provides some information in exchange for the data from Gon's ROM card). Back to Kurapika, they manage to identify two spies: Shachmono Tocino and Squala, who already work for the same boss and were asked to test the four rookies.

Kurapika together with five other hunters comes for a job interview. They are given preliminary orders and tested by being attacked by a number of fighters in black. Kurapika quickly understands that it is actually a Nen-based ability of one of the imposters, and counter-attacks him directly. Gon stops his father's tape when Ging tells he recorded a voice of his mother. The tape then destroys itself. Killua explains that the ROM card they found in Ging's box is meant for Joystation video game console.

Gon and Killua try to repair an antenna and a computer to set up Internet. Mito tells Gon all she can about his father Ging and hands over a mysterious box Ging left. Gon manages to open the box with his Nen and finds a ring, a tape and some piece of electronic equipment there. He and Killua listen to the tape where Ging introduces himself and welcomes his son to find him if he can.

Gon and Killua take a ship to get to Whale Island where Gon grew up. Killua is surprised that there is no bus and they have to walk, and that the house is really small. Mito, Gon's aunt, welcomes them and asks about the exam. When they go camping in the forest, they hear a shot and come running, seeing a bunch of poachers attacking the fox-bear and his cub. Easily beating them, they take the cub home. Gon wants to save him, but Killua insists on stopping his sufferings by killing him. Finally, they heal him with their Nen.

Kurapika's flashbacks with his master are seen here. The flashbacks tell how Kurapika passed his hidden Hunter exam and got his chains, what Nen type he has, and how he's changed. After he got his first job, Kurapika gets on the train where he meets someone that might become a future ally.

Gon and Killua master their Nen abilities and show them in perfection against matches with the other two guys that Killua talked to. Wing talks with them and tells Gon that he has passed the Hunter's Exam. Lastly, Gon and Killua venture out to Whale Island.

After Gon's match, Killua decides that he will compete as well, eager to test his own strength. Gido, Sadaro, and Riehlvelt kidnap Zushi to bribe Killua into forfeiting his matches with the three of them, so they can get easy wins. However, Killua makes sure that they will fight honestly and don't cheat. Sadaro withdraws due to his fear of Killua, who he says, "lived in the darkest corners of the world."

Gon and Hisoka continue their fight. Hisoka has attached his "Bungee Gum" to Gon's face and can pull him in to punch him. The referee awards points fast, leading to the quick win for Hisoka. At the end Hisoka is shown to have some connection with the Phantom Troupe; he has a spider tattoo on his back that he can remove. Machi tells them her boss won't be pleased if he doesn't make it to the Phantom Troupe meeting.

Gon and Killua learn their types of Hatsu; Gon is an Enhancer and Killua is a Transmuter. Gon fights Hisoka, and while over-matched, gets a punch in and gives back the number badge that Hisoka gave him during the exam. After that, Hisoka fights with his full power.

Gon is finally healed as he and Killua continue working on their Nen. Kurapika is shown looking for work, and being turned down. The girl who would hire him tells him if he can't see something invisible in the room, then he's not ready for a job. Leorio is shown studying medicine and looking at a picture of him and the other examinees. Hisoka begins a match with Kastro.

Gon and Killua are able to make it past Hisoka's Ren and enter the fights on the 200th floor of Heavens Arena. Gon immediately wants to test his new powers and fights against a man who uses his Nen and toy tops as weapons. He initially beats up Gon, but Gon learns to use his Zetsu to sense the tops and avoid them.

Killua and Gon learn about Nen from Wing, Zushi's teacher. Nen involves using your body's aura while fighting. On their way to register for the fights on the 200th floor, they're stopped by Hisoka. He doesn't think they're ready to fight at a high level. He uses his Nen to block them, and they have 3 hours to learn enough Nen to get past him, or Killua can never fight in Heavens Arena again.

Gon and Killua decide to fight professionally in order to train and make money. They go to the 251-story Heavens Arena, where every 10 floor increase represents more difficult opponents. Gon's power has increased dramatically from training on Zoldyck grounds, and he sends his opponent flying. Killua faces Zushi, another child who is competing, and Killua senses he can use a technique similar to Illumi's. Killua vows to meet Zushi on the top floor to learn more.

Canary and Gon's group arrive at the Butlers' Quarters and are greeted by Gotoh, Zoldyck family manager. He plays a game with the group, with seemingly deadly stakes. It turns out this was just to entertain them until Killua arrives. He does, and they all leave. At the airport, the group splits up but they all agree to meet in six months in Yorknew City.

Killua's mother Kikyo and brother Kalluto knock Canary out. They tell Gon that Killua doesn't have time to see them and they should leave. When Canary wakes up, she and Gon's group head to the house of security guards. Meanwhile, Killua has a talk with his father Silva, who makes Killua promise to never betray his friends. He then lets Killua leave to find Gon. Later, Silva tells Kikyo that Killua will be back because he's his father's son.

The group meets a butlers' apprentice while walking closer to their target. She has Killua's skateboard, and refuses to let them pass. Repeatedly Gon walks over a line she drew, and each time she sends him flying with her mace. Eventually, she explains that she is Canary, a servant of Killua. Canary tells her Killua gave the skateboard to her because they're friends, so she should let Killua's other friends pass. She lets them pass, but is immediately hit by an unknown projectile.

Gon, Leorio and Kurapika stay in the Zoldyck family's servants' quarters at the security guards behest. Zebro lets them in through the Testing Gate (weighing tons), and Gon feels he should have been able to let himself in. While they stay there, the guard trains them with weighted brooms, water buckets, slippers, cups and whatnot. They end up extremely strong. After 20 days they are able to open the gate themselves, and they start walking through the grounds towards the house. Gon and Kurapika can push the first gate of 2 tons open, and Leorio is strong enough for the second gate.

Gon, Leorio and Kurapika take a train towards Killua's home on Kukuroo Mountain. The last leg of the trip is spent on a tour bus that takes them to the Door to Hades, a giant gate that hides the path to the estate. A beast named Mike waits behind the gate, so Gon asks the security guard, Zebro to call Killua and have him open it from the inside.

Gon is determined that Killua has left against his will and Gon is going to find him. He fights Illumi for information and Illumi is about to kill him when Hisoka shows up. Illumi instead tells Gon that Killua is at the Zoldyck family home. Leorio is about to go to medical school and Kurapika is about to leave on his first job when both change their minds and decide to follow Gon as he looks for Killua.

Satotz explains to Gon that Killua failed the final stage. His opponent turns out to be his older brother Illumi in disguise. Illumi questions Killua and determines him unfit to be a normal person. He believes that Killua has a talent to be an assassin and tells him to return home. Illumi threatens to kill Gon if Killua even attempts to fight him, so Killua gives up and becomes silent for the rest of the exam. Killua murders Bodoro in the middle of his match with Leorio for no reason and is disqualified. Having heard this, Gon confronts Illumi and breaks his arm, deciding to go look for Killua.

Hanzo and Gon continue fighting. Hanzo is easily the better fighter, but when Gon won't concede, Hanzo is forced to accept defeat. Hanzo decides he'd rather lose than kill Gon, because he likes his attitude. Gon is knocked unconscious during the match and wakes up to find the matches are over. Satotz explains to him that he's a Hunter, and that Hisoka defeated Bodoro, Hanzo defeated Pokkle in a match, Killua conceded a match to Pokkle before facing his brother Illumi disguised as Gittarackur.

The next fight is between Hanzo and Gon. Although Gon tries his hardest to combat Hanzo, it is obvious he is no match for the ninja. Hanzo severely injures Gon and breaks his arm, but Gon will not admit defeat. Gon feels that if he is ever to find his father, he must pass the Hunter Exam now.

Hisoka and Kurapika fight in the first fight of the final stage. Hisoka toys with Kurapika at the beginning, but when Kurapika becomes angry they are on similar levels. This causes Hisoka to force himself to calm down. He then whispers something to Kurapika and declares himself the loser of the match. Kurapika is now a Hunter.

Chairman Netero interviews the nine remaining examinees (Gon, Kurapika, Leorio, Hisoka, Hanzo, Pokkle, Gittarackur, Bodoro, and Killua) in preparation for the final test. He asks each who they are interested in, and who would they least like to fight out of the nine. He then unveils a brackets system for the upcoming tournament between the remaining examinees.

Gon, Leorio and Kurapika become trapped in the cave with Ponzu. Leorio has been poisoned, and Gon gets bit numerous times to retrieve the antidote. Gon uses Ponzu's sleeping gas to put the snakes to sleep while holding his breath and rescuing everyone. Leorio takes Ponzu's number badge while she sleeps and Gon retrieves the number badges given to him by Hisoka, reasoning that it's OK to use them so that he can remain with his friends. The fourth stage ends.

Several days pass as Gon recovers from being poisoned. Killua is stalked by Imori, one of Amori Brothers. Imori's brothers Umori and Amori show up, and Killua bests them and gets his number badge from Amori. All the protagonists now have their points except for Leorio, who goes looking for his target Ponzu. He finds her in a cave, but is poisoned by snakes. Gon and Kurapika go inside to help him.

Gon gets Hisoka's number badge while Hisoka kills an examinee crossing his path. Gon is poisoned by Geretta and relieved of his badges. Hisoka kills Geretta easily and returns both badges: Gon's and his own. Gon tries to refuse it, but is unable to. Hisoka tells Gon he will kill him when the time is right, until then he will protect him. He punches him in the face and tells that he can return the badges only after he can return the punch.

Gon stalks Hisoka, and observes Hisoka's friend transform into his real appearance. Then Hisoka decides to hunt other participants for two more points.

The fourth stage of the Hunter Exam is a manhunt on Zevil Island. Each examinee must collect 6 points; their own number badge is worth 3, the number badge of their target is worth 3, and any other number badges are worth one point. Gon's target is Hisoka, and he practices catching birds with his fishing pole to prepare. He realizes he must attack Hisoka when Hisoka attacks his own target. Gon learns this by watching birds catch fish from the water.

The group works together to separate the battleship/hotel from the island before the second wave of the storm hits. Leorio gets stuck on the bottom of the ocean in a diving suit and Gon helps him escape. Gon is then saved by Hisoka. Kurapika is knocked out but the steering is done by a mysterious examinee who seems to be Hisoka's ally. They separate the ship just in time, and a blimp comes to pick them up.

The hotel owners leave the examinees stranded on the island. A map is found indicating another island nearby, and part of the group sets out immediately to find it, dying when a storm hits. Hanzo and Kurapika sense danger and are elected leaders of the people who stay. They learn of a storm that comes in daily waves, the second of which will submerge the island, so they have one day to escape.

The successful examinees are taken by blimp to an island hotel. In order to pay for the rooms, they dive to collect treasure from sunken ships. Kurapika explains to Leorio that everyone from his clan was killed by the Phantom Troupe for their eyes. When a member of the Kurta clan dies with their emotions ablaze, their Eyes become Scarlet and are treated as treasures.

The last test to get out of the tower has two paths: one is too long and the other will only allow three of the five to enter. Leorio and Tonpa start fighting to see who will stay, when Gon thinks outside the box. They choose the longer path, destroy the wall between the paths with axes provided so they could fight, and all five make it.

Leorio goes next. His opponent is Leroute, an attractive woman. He loses ten hours in bet to her so that he can grope her. He then loses the rest of their betting hours to her in a game of rock, paper, scissors. Killua then faces Johness the Dissector, a serial killer responsible for the murder of at least 146 people with his bare hands. Killua rips out his heart, explaining afterwards that Johness is an amateur and he is a pro.

Majitani feigns unconsciousness in an attempt to run out the clock. Leorio and the leader of the prisoners bet on whether he's faking. Leorio holds the man above a long drop, and Majitani wakes up. He concedes the match to Kurapika, but the group loses a large chunk of their time because of the bet.

Gon faces the next prisoner, Sedokan, in a match to see who's candle can burn the longest. Gon is given a candle that burns quickly, but because of this it isn't susceptible to the wind, and Gon drops it on the floor and runs to blow out Sedokan candle. Kurapika engages in a death match with the next opponent, Majitani, but refuses to kill him after seeing red (literally) and knocking the criminal unconscious.

The objective of stage 3 is to get down from a tower alive. The group is forced to team up with Tonpa, and their test is to win 3 out of 5 matches against tower prisoners. Tonpa takes the first match with a hardened-looking criminal, and promptly gives up. He explains that he doesn't want to be a Hunter, he just likes watching others fail and be killed.

Killua stops trying to take the ball from Netero because his killer instincts are surfacing. Anita escapes her handlers and attacks Killua, who comes close to killing Anita, but lets her live because otherwise Gon would get mad at him. Gon is never able to get the ball, but makes Netero use his left leg and both hands once, and is satisfied.

The protagonists and others have passed the second stage, and they fly towards the next stage on a blimp. Anita, a girl who failed the earlier test, sneaks aboard to get revenge on Killua for the death of her father. The Hunters capture her, and Chairman Netero offers to free her if Gon and Killua can take a ball from him.

While one of the examinees, wrestler Todo, criticizes Menchi and all Gourmet Hunters, Netero, the head examiner and Hunter Association's president, arrives and asks Menchi to give everyone another chance. The test takers collect spider eagle eggs, and Todo learns to respect Gourmet Hunters, vowing to return and take the test again.

The group starts stage 2 of the test, which is to satisfy Gourmet Hunters Buhara and Menchi with their cooking. Everyone satisfies Buhara's taste for BBQ pork, but they all fail to make sushi good enough for Menchi. She says all examinees fail.

Hisoka determines the real examiner by flinging deadly playing cards at each man, reasoning the true Hunter will live, and it's Satotz. Later, he plays at being an examiner and kills many examinees. Although Hisoka is able to kill all of his intended victims, he recognizes that Gon and Leorio are special and lets them live.

Tonpa has placed Leorio and another examinee near hallucinogenic sap. In a dream state, he explains that he wants to be a Hunter to get money so he can become a doctor who doesn't charge for his services. Gon and Killua bond. At the end of the first stage, a man appears to accuse the examiner of being a fake.

Gon, Kurapika, and Leorio reach the first stage of the Hunter Exam, a seemingly endless forced run through a tunnel leading by the examiner named Satotz. They are befriended by Tonpa, a man taking the exam for the 35th time, and meet Killua, another entrant. In the end Tonpa betrays Leorio, as Gon and Kurapika go looking for them.

Gon, Kurapika and Leorio continue on the test, arriving at a cabin in the woods. A husband and wife say they have been attacked by beasts, when a beast shows up and kidnaps the wife. Leorio stays to treat the husband's wounds as Gon and Kurapika help the wife. In the end it turns out the couple and the beasts are a family and they find the group worthy of continuing to the next test.

The ship's captain recommends they go towards a tree on the top of a mountain instead of directly at their goal. Leorio takes the bus and the rest head towards the tree. The bus is a trap, so Leorio abandons it and catches up with Gon and Kurapika. Matthew, an examinee they meet, travels with them and then betrays them. They successfully answer a riddle asked by an examiner and move on to the next test.

On the ship to the exam, Gon and Leorio meet Kurapika. The captain asks each for their reason to be a Hunter. Gon wants to find his father, Leorio wants to be rich, and Kurapika wants to be a force for justice.

Gon's aunt Mito gives him the go ahead to take the Hunter Exam after he has successfully passed her test, using a special rod from his father. Gon goes to town to catch a ship to the exam. In town, Gon befriends Leorio, after several run-ins with each other through the town. Leorio is also intent on taking the exam, and they take down a cruel animal show. In the end, they almost miss the ship, but through Gon's quick thinking, they manage to board the ship at the last minute.

Gon Freecss runs into a Foxbear in the forest. A mysterious stranger named Kite saves Gon by killing the beast. This man tells him that his father Ging is alive. Gon decides to take the Hunter Exam and become a professional Hunter, but can only do this after catching the Master of the Swamp to convince his Aunt Mito to let him do it. Despite her feelings, after Gon catches it, Mito allows him to begin his adventure.
