Goreinu is a professional Hunter and Conjuration-type Nen user who participates as a player in the game Greed Island during the same period as Gon Freecss and Killua Zoldyck, becoming one of their key allies.
Goreinu is introduced as one of the successful applicants in Battera’s Greed Island player selection exam.
He passes the selection and enters the game shortly after Gon Freecss, making him essentially part of the same intake.
He begins the game playing completely solo and, through his own efforts, collects more than 50 different specified pocket cards.
This alone places him among the more capable players on the island.
Despite his burly frame, thick eyebrows, visible arm hair, and tough-looking build, Goreinu is highly intelligent and sharp.
He is calm, rational, good at negotiation, and possesses excellent insight into people and situations.
He tends not to team up casually and usually avoids large groups, preferring to work alone.
However, once he acknowledges someone as a comrade, he is loyal, dutiful, and willing to share both risks and rewards.
Goreinu is left-handed, a small detail that fans often latch onto along with his appearance and ability for jokes and memes.
His character design, name, and gorilla-themed Nen beasts are widely thought to be modeled after a real-world comedian with a similar nickname and appearance.
He wears a sleeveless vest with a standing collar and loose sweatpants, giving him a casual, athletic look.
Beneath that look, he carries considerable pride in his own strength and hates backing down when it matters.
In terms of combat reputation, Razor explicitly states that Goreinu’s fighting level is “good enough,” indicating he is a genuine powerhouse even among Greed Island players.
He is also familiar with other Hunters and the general Hunter world, suggesting he has done numerous jobs prior to Greed Island.
The character is voiced by Kosuke Toriumi in the Greed Island OVA adaptation and by Hideki Tenjin in the 2011 television series.
Among fans, his famous reaction line to a harsh condition—“That’s nasty…”—has become iconic.
Early Greed Island Participation
Within the selection exam, Goreinu qualifies as a Greed Island player alongside Gon Freecss and Killua Zoldyck.
Once inside the game, he is the second among the successful applicants (after Gon Freecss) to actually step into the game world.
He initially chooses to proceed alone without forming a party.
During this solo phase he manages to gather over 50 different specified pocket cards, which is impressive given the game’s difficulty.
Later, Kazsule organizes a joint operation to stop Genthru and the Bomber group from clearing the game first.
The requirement to join is owning at least 50 types of specified cards, which automatically qualifies Goreinu and shows how far he has progressed on his own.
First Attempt at “A Strip of Beach”
Goreinu joins Kazsule’s coalition and participates in the attempt to obtain the specified card “A Strip of Beach.”
When he learns the true conditions for clearing that event, he mutters to himself, “That’s nasty…,” indicating he has quickly grasped the grim implications.
The first attempt fails, and the temporary team disbands.
Afterward, Goreinu corrects Kazsule’s misunderstanding about the event’s true nature.
Killua Zoldyck then interprets the meaning behind Goreinu’s earlier remark, confirming that Goreinu had already realized what the condition truly meant.
From this point on, Goreinu begins cooperating more directly with Gon Freecss and Killua Zoldyck.
Teaming Up with Gon’s Group
Deciding to continue targeting “A Strip of Beach,” Goreinu joins forces with Gon Freecss’s team.
He uses his own information network and judgment to carefully select players who might join their new assault team.
He also advises Gon Freecss and Killua Zoldyck on how to investigate the mysterious player calling himself “Chrollo Lucilfer,” who is actually Hisoka Morow in disguise.
This leads to their direct encounter with Hisoka Morow.
Goreinu is immediately disturbed by Hisoka Morow’s perverse and unpredictable personality.
He is reluctant to invite Hisoka into the team, but ultimately agrees when he weighs the practical benefits.
When Tsezguerra’s group is proposed as another ally, Goreinu initially shows hesitation.
Even so, he again chooses the realistic option and accepts Tsezguerra’s team on the condition that they act as insurance in case another party clears the game first.
Razor’s Event and the Dodgeball Match
In the renewed challenge against Razor, the team originally plans for Goreinu to participate as the wrestling representative.
However, a sudden betrayal by the player Bobobo disrupts the event structure and forces the team to face Razor and his Nen beasts under unexpected conditions.
In the revised format, eight people must participate in the dodgeball match against Razor.
The problem is that only six of them are genuinely strong, while the remaining players are weak filler participants.
Goreinu solves this by using his ability to create two Nen gorillas to effectively stand in for two additional competent players.
This clever use of his power allows the team to field a full roster without relying on more weak players.
At the start of the match, both of Goreinu’s gorilla Nen beasts are quickly taken out.
Razor then hints that eliminating them first was a deliberate prelude to targeting Goreinu and the others more directly.
Goreinu is provoked and retorts with something along the lines of “Interesting! Try it!” before hurling a powerful throw.
Razor casually catches the ball with one hand, shocking Goreinu and making him realize the huge gap in strength.
When Razor returns the ball, Goreinu instantly senses that taking it head-on would be suicidal and instinctively tries to escape outside the court.
Yet his pride will not let him remain a mere bystander, so he waits for another chance to strike.
Using his position-swapping ability, Goreinu sets up a surprise attack and comes close to forcing Razor out.
However, Razor’s Nen beasts respond brilliantly, the plan fails, and while Goreinu is stunned, Razor nails him in the face with a brutal pass, knocking him unconscious and eliminating him from the match.
Despite this defeat, Goreinu has demonstrated creative strategic thinking and the ability to threaten a far stronger Nen user under the right conditions.
His role in setting up plays and covering weaknesses is crucial to the overall success of the team.
After Obtaining “A Strip of Beach”
Once Gon Freecss and his allies finally defeat Razor and secure “A Strip of Beach,” they receive both the original and cloned versions of the card.
Gon Freecss tries to hand the original to Goreinu and Tsezguerra as a reward.
Both Goreinu and Tsezguerra decline the original and say they are satisfied with the cloned copies instead.
They recognize that, under the game rules, originals and clones have a clear difference in value, yet they choose the humbler reward.
Although their original goal regarding “A Strip of Beach” is achieved, Goreinu opts to continue working with Tsezguerra’s group.
Soon after, Genthru contacts them with threats, demanding that they hand over their cards.
Goreinu becomes a hidden ally supporting Tsezguerra’s side in their conflict with Genthru.
While Tsezguerra’s team eventually retires from the game due to injury and circumstances, Goreinu reveals a bold secret plan.
Before withdrawing, Tsezguerra’s party had swapped most of their important cards with the spell “Fake.”
This ensures that if Genthru seizes their binder, he will mostly get forgeries instead of the real specified cards.
After Battera’s personal reasons cause the cancellation of the original 50-billion-jen reward, Goreinu, together with Tsezguerra, decides to completely leave the game.
They then hand over all of their cards to Gon Freecss and his friends, propelling them toward eventual game clearance.
Division of Reward and Final Scenes
A new arrangement is made where a partial consolation fee is paid instead of the original huge prize.
Goreinu secures 4 billion as a success-related payment but immediately intends to divide it into four equal shares with Gon Freecss’s party.
He insists that this money is not the result of his efforts alone.
Gon Freecss and Killua Zoldyck refuse their shares, but Goreinu’s attitude showcases his strong sense of fairness and camaraderie.
In the apparent ending parade of the Greed Island game, Goreinu is shown celebrating and cheering on Gon Freecss’s team.
This scene marks his last major appearance in the story, though he is briefly seen again later during the election arc.
General Description
Goreinu’s ability is often summarized by his own line: “I become three people.”
He conjures two gorilla-shaped Nen beasts, one white and one black, and can control them remotely.
His skill is widely believed to be a composite of Emission, Manipulation, and Conjuration.
The gorillas themselves are conjured entities, controlled manually and capable of instant position swapping.
The ability is not automatic; it is clearly manual remote control rather than autonomous operation.
As a result, if Goreinu loses consciousness, the gorilla Nen beasts disappear immediately.
Later explanations in the series classify teleportation-like abilities primarily under Emission.
Because Goreinu’s technique involves instantaneous spatial repositioning, many fans reclassify his power as primarily Emission-based, with supporting Conjuration and Manipulation.
Since conjured objects usually require Manipulation-type skills to be controlled at a distance, his gorillas fit that rule as well.
Consequently, some readers believe his Conjuration affinity may actually be lower than originally implied, and that the gorilla form exists as a kind of self-imposed restriction or condition.
Under this interpretation, making the Nen beasts clearly visible as gorillas to everyone, not just Nen users, may amplify the ability in exchange for aesthetic or thematic constraints.
In other words, the gorilla appearance might be functionally meaningless and chosen purely for restriction and flavor.
There is also a fan theory that Goreinu may actually be a Specialist, since combining Emission, Manipulation, and Conjuration at a high level is supposed to be extremely difficult within the standard Nen schema.
Specialists are said to lack conventional strengths or weaknesses, making such a hybrid power more plausible.
White Sage (White Goreinu)
White Sage (White Goreinu) is the ability associated with the white gorilla Nen beast.
It allows Goreinu to instantly swap positions between himself and the white gorilla.
In the Razor dodgeball game, Goreinu uses White Sage primarily to dodge lethal shots.
When Razor sends a devastating ball his way, Goreinu can survive by exchanging locations with the white gorilla at the last moment.
The effect is extremely fast, appearing instantaneous to observers.
There is no visible chant, gesture, or complex ritual required for activation, suggesting simple mental commands are enough.
Black Sage (Black Goreinu)
Black Sage (Black Goreinu) is the ability associated with the black gorilla Nen beast.
It swaps the position of a third party with the black gorilla.
In the story, Black Sage is used to launch a surprise attack on Razor.
Goreinu positions the black gorilla and then exchanges Razor’s position with it, nearly forcing Razor out of bounds.
The speed of activation is again portrayed as extremely high.
Crucially, Black Sage appears to work without any complicated conditions, contracts, or restrictions beyond having the gorilla and target within range.
This means that if an enemy is within effective distance, Goreinu can forcibly teleport them into a deadly zone, trap, or disadvantageous location.
The fact that he manages to apply the effect to Razor—a much stronger Nen user—without any sign of Razor predicting or resisting it is a cornerstone of fan speculation.
Because the power has almost no intrinsic offensive damage but offers nearly unconditional position manipulation, its versatility is considered enormous.
Many fans view Black Sage as a powerful “first-strike” or “checkmate setup” tool, especially in ambush or battlefield-control scenarios.
However, its true potential is never fully explored on-panel, as the series only shows it being used once.
Without an official in-universe explanation, most deeper details remain guesswork.
Goreinu was initially grouped by some readers with Conjuration-type users like Kastro, whose abilities involve creating Nen constructs.
Later Nen explanations that link teleportation and spatial transfer to Emission shifted opinion toward classifying Goreinu as primarily an Emission-type user.
Since controlling a conjured object at a distance requires Manipulation attributes, and making that object visible to all can function as a self-binding condition, Goreinu’s ability checks multiple boxes.
The gorilla theme might simply be a stylistic choice that doubles as a restriction, increasing power in exchange for inflexibility or stigma.
Additionally, specialty-based theories argue that a Specialist could more realistically blend Emission, Manipulation, and Conjuration into a single unique technique.
This aligns with the notion that Specialists stand outside normal affinity rules.
Regardless of classification, fans generally agree that Black Sage is an exceptionally broken utility ability if used creatively.
With proper setup, it could theoretically override differences in combat strength by sending stronger enemies into lethal traps or isolating them from allies.
Tsezguerra’s surprised reaction when Goreinu first reveals that he has two separate gorilla Nen beasts is also noteworthy.
If Goreinu had already fully demonstrated this power during the selection exam, Tsezguerra’s response would be odd, so many conclude that Goreinu either used a different technique then or relied on raw combat ability without showcasing his signature Nen power.
Within the narrative, Goreinu ends up playing a support-heavy role and does not get a long list of flashy victories.
Even so, he clearly possesses the brains, battle sense, and raw power to justify his own high opinion of his abilities.
Beyond Nen, Goreinu earns admiration for his grounded personality.
He is fair, considerate, and prepared to share both cards and prize money with allies, reinforcing his reputation as one of the more decent and reliable Hunters in the story.
At the same time, the timing of his introduction—right after an arc that painstakingly explained how Conjuration training works through Kurapika’s chains—made the sudden appearance of “gorilla conjuration” feel comically absurd to many readers.
As a result, while Goreinu is respected, he is also loved as a meme character whose gorilla-themed Nen beasts are perpetually joked about.
