12 歲的小剛想參加獵人試驗，並追隨父親的腳步，但他得先實現對撫養他長大的米特阿姨許下的承諾。

小剛、里奧里奧和古拿比加抄近路到試驗會場時，碰上一名年長的女士擋住去路，要求他們得先回答一道題目。

小剛、古拿比加和里奧里奧抵達試驗會場，許多參加者早已到場，包括愛講話的忍者半藏。

薩茨負責在獵人試驗的第一階段，用看不見終點的長跑，來評估參加者的耐力和心理狀態。

穿越冗長的地下隧道後，參加者發現自己置身於霧氣瀰漫的濕地，還遭到怪獸攻擊。

和希索加吵了一架後，小剛與朋友安全抵達第二階段試驗的會場，這一關要測試大家的烹飪能力。

小剛和基路亞搭上飛行船，準備迎接試驗的第三階段時，受邀參加一場簡單的遊戲，贏了就有望成為獵人。

飛行船來到試驗第三階段的會場：賤阱塔的塔頂。參加者必須在 72 小時內到達地面才算通過。

小剛與古拿比加雙雙獲勝，率領團隊以 2 比 1 領先，但對手卻宣稱喳唬只是昏過去而已，所以古拿比加還沒比完。

里奧里奧不敵對手孤注一擲的心理遊戲，也讓團隊陷入困境，這下大夥的命運全掌握在基路亞身上了。

小組成員被迫原地停留 50 個小時，只好使出渾身解數過關。他們獲准回頭繼續接受試驗後，還得克服更多障礙。

小剛寫信給米特阿姨和奶奶，細述從離開那天，到最近的賤阱塔挑戰，所經歷的旅程。

第四階段試驗的參加者前往賽比擄島，每位候選人都必須在這裡湊齊 6 分才能通過。

小剛等待完美的時機發揮技巧，利用釣魚竿搶走希索加的號碼牌。稍後古拿比加則與里奧里奧結盟。

希索加跟蹤古拿比加和里奧里奧。大夥來回交涉，化解了一場戰鬥之後，希索加尋找新的目標。

基路亞受不了伊摩里一路尾隨他，於是對他下戰帖。另一方面，小剛、里奧里奧和古拿比加研擬一項計畫，好拿到龐珠的號碼牌。

小剛和朋友們被困在一處毒蛇洞穴中。他們想方設法救助慘遭蛇吻而愈發虛弱的里奧里奧。

在獵人試驗的最後階段，半藏和小剛率先上陣比賽。小傑完全無法招架半藏的攻擊，卻不願放棄。

小剛對抗半藏時，手臂被折斷了。他在床上醒來後，薩茨恭喜他通過了獵人試驗。

基路亞被迫痛下殺手，令小剛驚訝不已。他表明要去枯枯戮山救基路亞。

Gon, Kurapica, and Leorio arrive at Kukuroo Mountain only to find out that they cannot get close to the Zoldyck family estate. The Zoldyck family owns the mountain and all of the surrounding forest and the entire region is gated shut. There is a guard outpost immediately outside of the gate, but instead of serving as a guard, the man working in there actually cleans up the mess created by the watchdog whenever there are intruders into the grounds. Gon, unwilling to give up on "rescuing" Killua, learns from the gatekeeper that the actual door is the massive stone gate and anyone who enters via that path will not be attacked by the watchdog. Leorio tries to pull and push on the gate, to no avail. The gatekeeper informs them that the gate opens up different amounts of stone slabs based only on the strength of the person; however, the least amount of strength anyone needs to open the smallest portion of the door requires two tons of strength on each side.

Gon and his friends have decided to pass through the Trial Gate to see Killua. First, they must train in the servants' residence until they can open the gate. Meanwhile, Killua has learned that Gon and the others are here to see him. Gon, Leorio, and Kurapika are able to open the gate after completing their training, but the apprentice butler Canary stands in their way.

With help from Canary, who is concerned about Killua, Gon and his friends are getting closer to the mansion. However, Kikyo tells them that Killua cannot see them as he is in solitary confinement. Meanwhile, Killua has been summoned by Silva and asked if he wants to see his friend? Killua answers truthfully, and he is allowed to go see his friends...

Gon, Kurapika and Leorio arrive at the Butler's Quarters, where the Head Butler entertains them while waiting for Killua. But just what game does he have in mind, and what are the stakes?

A letter from Gon arrives at Whale Island for Mito... (A recap of everything that has happened.)

Gon and Killua arrive at the Heavens Arena and begin to work their way up, making a new friend, Zushi, who is trained in the martial arts.

While working to understand Nen and Ren, Gon and Killua run into a familiar acquaintance.

After reaching the 200th floor, Gon and Killua run into Hisoka's barrier of Nen. They ask Wing to use the violent method for activating their Nen potential. As the deadline for registration draws near, they begin training in one of the four major principles of Nen, Ten.

Gon faces the Nen user Gido in his first 200s Heavens Arena match. Gon uses Ten to protect himself, but he soon finds himself on the defense against Gido's Dancing Tops. As Gon desperately tries to find a way to fight back, he makes a bold decision...

A month has passed since Gon was seriously injured, and Hisoka and Kastro are about to fight in Heavens Arena. Kastro was able to knock Hisoka down in the past and sounds very confident in his interview. Hisoka appears unperturbed by the upcoming fight.

Kastro has used his ability to create a clone of himself with Nen to sever Hisoka's arm and take an advantage in the fight. However, despite losing both arms, Hisoka appears to be perfectly calm. Kastro loses his cool and attacks Hisoka.

After two months, Gon and Killua are finally allowed to practice Nen again. That's when Gido, Sadaso, and Riehlvelt appear before them and tell them to fight them in the arena. Gon and Killua refuse, but Killua finds Sadaso's behavior to be very suspicious.

Gon has fights against Gido and Riehlvelt coming up. He's still mad about what they did to Zushi. Gon is able to withstand Gido's attacks and overwhelm him in battle. This causes Hisoka to smile.

Gon and Killua begin training in Hatsu, the culmination of everything they've learned about Nen. And finally, Gon challenges Hisoka to return the favor from the Hunter Exam.

After landing a punch on Hisoka, Gon returns the tag from the Hunter Exam. Hisoka is ecstatic to see Gon's development and uses his own Nen to attack. Gon is scared, but he recklessly continues to attack! Will he emerge victorious.

After learning Nen and becoming a true Hunter, Gon returns to Whale Island with Killua. When he arrives, Mito has a box for him. She was told by Ging to give this box to Gon once he became a Hunter. However, it appears that the box cannot be opened.

Gon and Killua have begun to listen to the cassette tape left behind by Ging in anticipation of Gon becoming a Hunter.

Having learned his Nen ability, Kurapika pursues a Hunter's work that will get him close to the New York auction.

Kurapika and the other job candidates have to battle their way out of the employers mansion... if they ever hope of obtaining any of the items they even need for the job.

The biggest auction in the world is about to take place in York New City. The Phantom Troupe leader, Chrollo, has instructed the members to gather in the city. For what purpose? The band of murdering thieves is about to make its move.

The auction is finally about to begin. Gon, Killua, and Leorio are working hard to amass enough money to buy Greed Island. Kurapika has been assigned to monitor the auction house. Meanwhile, the Phantom Troupe draws close. All paths will soon cross in York New City.

The Phantom Troupe attacks the underground auction held by the Mafia. Afterwards, there is no sign of the merchandise or guests. The Mafia place a reward on their heads and begin pursuit. Kurapika and the other bodyguards on patrol join the pursuit. Kurapika is drawing closer to the Phantom Troupe.

After Uvogin slaughters the Mafia's pursuit, the Mafia dispatches their secret weapon, the Shadow Beasts. However, Uvogin is able to defeat them by himself. During the battle, the spider tattoo on Uvogin's back is revealed, and Kurapika springs to action.

Kurapika was able to capture Uvogin, a member of the Phantom Troupe. Kurapika struggles to control his rage as Uvogin makes demands as though he isn't a captive. That is when Kurapika receives an e-mail from Hisoka...

Uvogin was able to escape with some help from his fellow bandits. However, after the blow to his pride, he is determined to track down and Kurapika and defeat him. Kurapika realizes that the Phantom Troupe has identified their location and moves the boss to a safe place while awaiting the Phantom Troupe's arrival by himself.

The anticipated battle between Kurapika and Uvogin begins! Can Kurapika really withstand Uvogin's abilities, and just what are the full extent of the powers in Kurapika's chains?

Gon, Killua, and Leorio are trying to get their hands on enough money to buy Greed Island. As they pass through the market, Gon stumbles across a way to identify valuable items. The plan is to buy cheap and sell low, but someone else is bidding on all their items.

Gon and his friends are hoping to win the reward that's been placed on the Phantom Troupe. At the same time, Machi and Nobunaga have been dispatched to search for the "chain user" because Uvogin hasn't returned. Gon and Killua receive a tip and begin shadowing the two Troupe members.

Gon and Killua have been captured by the Phantom Troupe. They are questioned about the chain user that the Troupe is searching for, but the two of them don't know that the chain user is Kurapika. As they're about to be released, Nobunaga decides to keep them around as potential recruits for the Troupe.

The auction has been rescheduled, and the Mafia expects the Phantom Troupe to attack again. The Ten Dons have hired multiple assassins to deal with the Phantom Troupe. Light Nostrade sends Kurapika to join the assassins in dispatching of the Troupe.

The Troupe is attacking the auction with all their power. The Ten Dons hired assassins are no match, except for Zeno and Silva.

The leader of the Phantom Troupe is dead... Kurapika is shocked by the news. Unconvinced, he tries to get a glimpse of the body. Meanwhile, the dead bodies of the other Troupe members have been discovered.

Gon, Killua, Kurapika, and Leorio are finally reunited. Kurapika reveals his Nen powers to the others. However, Killua is afraid that Kurapika is now in danger because one of the Troupe members can read minds. Meanwhile, Chrollo is using the fortune telling power he stole from Neon to tell the fortunes of the Troupe members.

After Chrollo tells fortunes for all of the Troupe members, they suspect that Hisoka has betrayed them. Hisoka's desire to fight Chrollo drives him to take a big risk by altering his own fortune. Meanwhile, after learning that the Troupe is still alive, Kurapika teams up with Gon and friends and work on a plan to capture Pakunoda.

Chrollo uses the information he has on Neon to identify the location of the chain user, Kurapika. Meanwhile, Killua is keeping an eye on the Phantom Troupe base when he is joined by Melody, who helps determine that the Troupe is headed towards Kurapika's hotel. The Troupe is finally closing in on Kurapika.

The Phantom Troupe has learned that Kurapika was the one who killed Uvogin. It's only a matter of time before they realize that the captured Gon and Killua are working with Kurapika? Chrollo takes Gon and killua to the hotel lobby, where Paknoda and the other Troupe members are waiting. Suddenly, the lights go out. Gon and Killua try to escape in the darkness. But Chrollo is the one who has vanished...

Kurapika has captured Chrollo. He offers to release Chrollo if Pakunoda brings Gon and Killua to him. However, Kurapika is unable to control his emotions in the presence of the Troupe leader.

The game Greed Island, which holds a clue to finding Ging, is finally on auction. Gon and Killua ask the winning buyer to hire them as players, but they're told that their Nen is too weak. They begin to work on special abilities so they can be selected as players.

Gon and Killua are trying to get themselves chosen as Greed Island players. Tsezgerra, the judge, says that he will make his decision after they show him his Nen. Only 32 of the 200 applicants will pass.

Gon and Killua have finally made it inside the world of Greed Island, their clue to finding Ging. However, all they found was a message from Ging telling Gon to enjoy the game. Their first step is to find a city and gather information. There, they receive an invitation to join a group that's trying to clear the game.

Gon and Killua set off for Masadora in search of spell cards. On the way, they run into many different monsters. However, they struggle against some of the stronger monsters. A girl named Biscuit watches as they fight their way through.
