Suzuki later gives the Sword of Trials to Kuwabara and the Seed of De-Incarnation to Kurama, which he had previously given to Shishiwakamaru and Reverse Urashima respectively, to aid them against Team Toguro. In the past Suzuki fought Younger Toguro but was spared after begging for his life.

Team Toguro are the fifth and final team that Team Urameshi faces in the Dark Tournament. They are the winners of the previous tournament. Younger Toguro fights the preliminary round alone, while his three teammates sweep the semifinal round. Togashi considers the Toguro Brothers to be his favorite villains in the series because they are "fundamentally unrestrained." The Toguro Brothers came in eleventh place in the series' first popularity poll. In the second, Younger Toguro placed tenth and Elder Toguro eleventh. The brothers came in seventh in the American ''Shonen Jump'' poll.Younger Toguro
: is first introduced alongside his older brother as , demons who provide monsters for things such as sideshows or assault forces, hired by Gonzo Tarukane to make Yukina cry. However, it is revealed that their actual client was Sakyo, who is also their team sponsor in the Dark Tournament. Younger Toguro is a human turned demon and the main antagonist during the Dark Tournament arc. His ability is purely physical strength, able to regulate how much of his maximum power he releases, ranging from 0% to 100%. With each increase comes a burst of demon energy and his muscles thicken and enlarge themselves. At full power he needs to feed on aura to maintain such immense power, leading him to absorb the aura of weaker creatures. Once a great martial arts master and Genkai's lover, Toguro was psychologically scarred when a demon named Kairen killed all of his students while inviting him to participate in the Dark Tournament. Toguro defeated Kairen in the final round to win the tournament and decided he did not want to age and lose his power, therefore he asked to be turned into a demon. 50 years later he invites Yusuke to the tournament in hopes of finally finding a fighter worthy of his full 100% power. Although he stops Yusuke's final attack in the final round, Toguro's body is destroyed and he dies. In the afterlife, he is offered a lighter sentence by Koenma due to his time as a martial artist, but Toguro refuses and requests the harshest sentence there is: 10,000 years of torture in hell for 10,000 cycles, with his soul ceasing to exist afterward. In the English anime dub this is changed to him requesting limbo. Feeling it obvious what Team Urameshi would wish for as their prize for winning the tournament, it was Toguro who suggested Koenma resurrect Genkai.Elder Toguro
: is first introduced alongside his younger brother as Brokers of Darkness, demons who provide monsters for things such as sideshows or assault forces, hired by Tarukane to make Yukina cry. However, it is revealed that their actual client was Sakyo, who is also their team sponsor in the Dark Tournament. Elder Toguro is a human turned demon shapeshifter. He usually rides on his much larger brother's shoulder and often fights alongside him. Elder Toguro can alter the shape of his body to form weapons and shields or to move his organs to escape harm, and has regenerative abilities, almost to the point of immortality. In the second to last match of the Dark Tournament, Kuwabara works around his regeneration by squashing him with the Aura Sword (whose shape had been manipulated into that of a flyswatter), and Elder Toguro is declared the loser. But Elder Toguro reveals he is still alive as his brother is about to begin his fight against Yusuke and offers to be his weapon. However, Younger Toguro punches him to pieces and off the island, saying that the fight will be one-on-one only. After being nearly destroyed by his brother, Elder Toguro slowly regenerated until he was a head found by Sensui. Seeking revenge he informed Sensui about Yusuke, who decided it was time to begin his plan to destroy humanity. Toguro was later devoured by Sadao Makihara, but Toguro easily took control of his body and acquired Makihara's abilities as well as those of Makihara's past victims. In his fight with Kurama, Makihara/Toguro is captured in a parasitic tree that casts illusions, and because of Toguro's immortality, he is stuck fighting Kurama's ghost for eternity.Karasu
: is a master-class demon bomber. Like Bui, Karasu fought against the Toguro brothers and lost and subsequently became a member of Team Toguro. He is able to use his aura to create and control bombs undetectable by weaker demons. Karasu displays sadistic tendencies, stating that he favors Kurama and becomes depressed when he destroys what he likes, but enjoys being depressed and therefore is looking forward to killing him. He wears a mask over his mouth which seems to restrict his powers. He is also able to use his entire body as an explosive. Karasu fights Kurama in the opening match of the final round of the Dark Tournament. Due to letting his guard down, Karasu is killed by Kurama, whose fox demon powers have started to return to his human body. But because Kurama did not get up until after a ten count, Karasu is ruled the winner. Karasu is a popular character with fans, coming in eighth place in the series' second popularity poll.Bui
: is a demon warrior who possesses an immense battle aura, that even allows him to levitate. He wears heavy armor to suppress his aura and wields an ax larger than his own body. During the third match of the final round of the Dark Tournament, Bui faces Hiei and loses as the latter has mastered the Black Dragon Hellfire. When he was younger, Bui fought Younger Toguro and lost. With the prospect of a rematch, he trained and improved, but so did Toguro. Having lost to Hiei, it proves he will never beat Toguro, and so Bui asks Hiei to kill him, which Hiei refuses.Sakyo
: is first introduced as a young member of the , a group of wealthy humans who deal with demons and compete in high-stakes gambling, betting on whether Yusuke and Kuwabara will succeed in defeating Tarukane's bodyguards, the Toguro brothers, and their men.

Sakyo is the sponsor of Team Toguro in the Dark Tournament. He is a sociopath, who grew up torturing and killing animals and people. He has an affinity and knack for gambling, occasionally putting his own life on the line just for the thrill of it. With his expected monetary winnings from the tournament, Sakyo plans to create a large hole or portal linking the Demon Plane with the Human World, for no reason other than to see what happens. After Younger Toguro's death and having staked his own life on the victory, Sakyo self-destructs the tournament arena and is crushed to death. In the anime, he forms a romantic bond withSensui Seven
The are a group who are trying to open a portal linking the Human World with the Demon Plane. Led by Shinobu Sensui, it is composed of seven individuals referred to by nicknames which are also the names of their abilities.

Born with a powerful sixth sense, Sensui was a prodigy aura user and demon hunter from an early age. He was recruited as Underworld Detective and worked tirelessly as an advocate for justice, believing demons to be humanity's enemy. During a case to stop a small Demon Plane portal created by the Black Book Club, including Sakyo, Sensui found a room where humans were torturing demons and bathing in their blood. After Sensui saw the cruelty of humans, in antithesis of what he believed, he went mad and murdered everyone in the room. He began to question humanity itself and soon disappeared taking The Black Chapter with him. Sensui waited ten years for a new Underworld Detective to emerge before coming out of hiding and enacting his plan to judge the human race. During his years in hiding, Sensui created six alternate personalities (seven including himself) to deal with the pressures of battle; Shinobu is the original and central one, while three others deal with matters of combat. Only three of the seven are seen, while a fourth is described, they are: , a talkative, argumentative and proud speaker who is in control for the majority of the arc; , a sadistic killer with a gun built into his arm who takes over as Yusuke gets the upper hand fighting Minoru; , a shy, naïve and sensitive female personality only spoken of by Itsuki; and Shinobu, the original personality who takes over after Kazuya is beaten by Yusuke for attempting to kill Koenma. Sensui is a master of , a fighting style that uses the upper body for defensive maneuvers that act as transitions for offensive kicks. Sensui also wields , a special type of aura that is said to be the purest of all. After Sensui takes a fatal blow when Yusuke's demon ancestor takes over Yusuke's body briefly, it is revealed that he suffered from aggressive malignant tumors with only two weeks left to live. Before dying, Sensui states that he longed to have demon heritage, that he created the portal so that he could die in the Demon Plane, and wishes that he be reincarnated as a demon.Itsuki/ Gatekeeper
: , also known as , is a demon who was Sensui's partner as an Underworld Detective. They were enemies when they first met and Itsuki lost the fight, but Sensui spared him after seeing a glimpse of his human side.

Itsuki is a , a demon who possesses the which allow him to traverse dimensions and who can control lesser demons in different dimensions, such as the 2-D demon . He is the one who creates the portal to the Demon Plane. Itsuki has the Inverse Man transport Kuwabara, Kurama, and Hiei to hyperspace in order to watch Yusuke's fight with Sensui without interference or escape. After Sensui's death, Itsuki informs Koenma that he can not have Sensui's soul as he did not want to go to the Underworld and takes the body into another dimension. Itsuki is one of Togashi's favorite characters. After the series ended, Togashi stated that he wishes he had been able to expand on the character's twisted psyche. He also noted the portion of the plot where Itsuki speaks inside the Inverse Man to be his favorite of the series because it reflects how the manga artist was feeling at the time.Minoru Kamiya/ Doctor
: , also known as , is a human physician and one of Sensui's comrades. His Doctor ability allows him to use his hands like scalpels, reattach limbs and create and infect people within his territory with an aura virus. Kamiya also enhanced his physical abilities and can control the adrenaline so he does not feel pain. He knows that finishing the portal to the Demon Plane will mean the destruction of the Human World and himself but believes that death by a demon is a fitting end for him over disease or old age. Kamiya is killed by Yusuke, saving those infected by his virus, but quickly revived by Genkai and then arrested. At the end of the arc, Kamiya escapes from jail, resuscitates Hagiri, and reconstructs his own face to evade police.

But it is later revealed that Hiei was very precise not to kill him and he was healed by Kamiya.

He later disappeared after high school.Kiyoshi Mitarai/ Seaman

His ability Seaman allows him to mix his blood with liquids to create shape-shifting nearly invulnerable creatures made of water. His territory is contained within these creatures that he traps people in to drown. Mitarai is psychologically scarred after watching the Black Chapter videotape and believes that all humans, including himself, are inherently evil and should be wiped out. He attacks Kuwabara and his friends, but is defeated when Kuwabara's regains his aura and acquires the new ability to summon the Dimensional Sword. Sensui knew Mitarai was weak and uncertain and therefore had him bugged with a listening device and tries to kill him alongside Hagiri in Yusuke's apartment. Having been saved by Kuwabara twice and then Botan, Mitarai rethinks his stance on humans and decides to help in the fight against Sensui. After the final fight, he lives a normal life, and gets into his school of choice. He later devotes his time to environmental and international issues. He is voiced byTsukihito Amanuma/ Game Master

However, Kurama informs Amanuma that Sensui took advantage of the child and chose a game where the antagonist dies if beaten, causing Amanuma to die as well. Shaken, Amanuma loses the final match and Kurama wins, killing the boy. However, Amanuma is brought back to life by Koenma's pacifier, just as Sensui intended for him to waste the power. He later lives a normal life and even makes new friends his age.Sadao Makihara/ Gourmet
: , also known as , is a human and one of Sensui's comrades. His ability Gourmet allows him to eat other beings and gain their powers as his own. At some point he devoured Shigeru Murota and the regenerating head of Elder Toguro, but the immortal demon ends up taking over Makihara's body.

Kurama captures Makihara/Toguro in a parasitic tree that casts illusions and because of Toguro's immortality and evil nature, he is stuck fighting Kurama's illusion for eternity.Demon Plane
Yomi
: is the newest of the three demon kings vying for control of the Demon Plane. He was Kurama's second in command as bandits working to build a nation. Yomi was reckless and brash, and Kurama sent an assassin who blinded him before fleeing. Kurama then left for the Human World and Mukuro and Raizen rose to power. Having equaled them in power and with Raizen dying, Yomi plans to take over both the Demon Plane and Human World. He calls Kurama to aid him and threatens his human family to get him to stay. After Yusuke proposes the Demon Plane Unification Tournament, Yomi is forced to accept and announce the dissolution of his nation. However, this is initially a bluff, until his fighting spirit is roused and he abandons his plans. In the tournament he defeats his young son and Yusuke, before losing to someone else.Mukuro
: is one of the three demon kings vying for control of the Demon Plane. She recruits Hiei, who becomes her top warrior. She was born into slavery under a humanoid demon named Chiko, who continuously tormented her, particularly on her birthday, with the implication of sexual abuse. After pouring acid on herself at seven years old, Chiko lost interest and Mukuro was free. She killed indiscriminately, before finding Hiei's lost Tear of Ice jewel, which had the same calming effect on her as it does him. Despite missing half her body, Mukuro rose to prominence equal to Raizen. She is quick to accept Yusuke's proposal of the Demon Plane Unification Tournament, dissolving her nation. In the tournament she defeats Hiei, before losing to someone else. At the end of the series, Hiei learns that Chiko implanted a single memory of himself being kind into Mukuro's mind, which she remembered every time she thought of getting revenge. He also trapped him in a parasitic plant which he gives to her on her birthday. In the anime, Mukuro's backstory is changed to exclude the parts about her being a sex slave, and that she was simply an abandoned child found by Chiko and taken in for slavery. Togashi has stated that Mukuro is one of his favorite characters. The author had desired to write more about her abuse before the series ended.Raizen
: is one of the three demon kings vying for control of the Demon Plane and Yusuke's ancestral father. Nearly 700 years ago, Raizen, then in the Human World, fell in love with a human woman.

Raizen immediately falls in love with her, they mate that night and he vows to himself to never eat human flesh until they meet again. However, they never did as she died giving birth. Raizen summons Yusuke to the Demon Plane as he is on the brink of death from starvation and requires someone to take his throne. During Yusuke's fight with Sensui, he momentarily takes over his body to defeat Sensui. He later dies, making Yusuke king of his domain.Shigure
: is a demon osteopath and one of Mukuro's top warriors. He is the one who gave Hiei his Evil Eye, so that he could find the Ice Maiden's country and his Tear of Ice jewel, and taught him basic swordsmanship. Shigure only operates on patients that interest him and takes part of their "life existence" as payment, which in Hiei's case was that he could never reveal his relation to Yukina. Shigure fights Hiei as part of Mukuro's testing of whether Hiei can qualify to be the right-hand man. He wields the large that looks like a large hula hoop. In the quick battle, they both lose an arm, but Shigure also loses the top half of his head. However, Shigure then appears fully healed in the Demon Plane Unification Tournament as an opponent of Kurama, whom he loses to, and is later seen doing patrol work with Hiei at the end of the series. In the anime, after losing to Kurama, he apparently commits suicide, stating that a swordsman never loses twice.Shu

: is Kazuma's seventeen-year-old sister. She is an aspiring beautician and has a sixth sense even stronger than her brother's. It is Shizuru who recommends her brother see master Genkai for advice on the side effects of his sixth sense, getting him caught up in her tournament to find a pupil. Considerably down to earth and deadpan in most scenes, her role is mainly to act as the tough mother-figure to Kuwabara. Her role grows somewhat during the Dark Tournament, and appears again at the end of the series. However, in the anime she has a brief romantic connection to Sakyo as he saves her numerous times from demon guards at the stadium, and is given his lighter to remember him by as he dies in the stadium's destruction and takes over the role that Yusuke's mother had in the Sensui arc of the manga. Yoshihiro Togashi named Shizuru his favorite female character of the series "because she keeps her cool."Yukina
