'''Species:''' Spirit Being\\
'''Main Power:''' Healing]

-->''Now I understand what kind of person you are; it's in my guidebook! Rather than be scared or surprised, you yell a lot and tell me I don't know what I'm talking about.''

->Voiced by: Sanae Miyuki (JP), CynthiaCranz (EN)

Chief ferry girl across the River Styx, Botan is the perky shinigami sent to retrieve Yusuke's soul after his unexpected death. She initially serves as his guide back to life and becomes his assistant upon his appointment as Spirit Detective.
* ActionGirl: Specifically in the Four Saint Beasts storyline, where she easily fends off possessed people with a baseball bat and then attempts to save Keiko.
* BadassAdorable
* CatchPhrase: "Bingo!"
* CatSmile: Would often make this face... in every occasion too.
* TheChick: Only female member of the main team.
* CoolBigSis: To the team as a whole.
* TheGrimReaper: A pleasant Japanese subversion.
** DontFearTheReaper: Both in apperance (cute and perky) and in role (guide to the after life)
* GenkiGirl: Her liveliness and general energy is one reason why Yusuke didn't think she was a grim reaper.
* HealingHands
* ManicPixieDreamGirl: She fits the personality type (minus crazy impluses) but her relationship with Yusuke was always platonic.
* TheNotLoveInterest: To ''anyone''.
* OohMeAccentsSlipping: In the English dub, she has a slight English accent which diminishes over the course of the series...then pops back up in random intervals.
* OnlySaneWoman
* PurpleEyes
* {{Shinigami}}: A Shinigami with character details (such as the oar she rides on and her blue hair) referencing the Japanese Buddhist myth of the Sanzu River, analogous to the Western River Styx. Her primary function is as a psychopomp, although that appears less and less as the series focuses more on Yusuke's battles with demons.
** The English dub has her call herself the Grim Reaper and Guardian of the River Styx instead.
* TeamMom
* YouGottaHaveBlueHair: Or baby blue hair.

[[WMG: Keiko Yukimura]]
'''Species:''' Human\\
'''Main Power:''' One hell of a slap!]

-->''Yusuke, you perv! People like you should be strung up in the street! Dumb boy! Hasn't grown up a bit since he was 4 years old!''

->Voiced by: Creator/YuriAmano (JP), Creator/LauraBailey (EN)

ClassRepresentative of Sariyashki High and Yusuke's childhood friend, Keiko is his LoveInterest throughout the series.
* ActionSurvivor: Has [[{{Muggles}} no supernatural powers]] to defend herself from demonic and powerful forces. She gets by by being {{plucky|Girl}} and resourceful, shown especially when she and Botan are up against zombies controlled by insects.
* AllGirlsWantBadBoys: Her and Yusuke. [[SubvertedTrope Justi]][[JustifiedTrope fied]] in that while the rest of the school thinks he's some kind of mob boss she knows he's not as bad as he seems because they grew up together.
* ArmorPiercingSlap: Especially when Yusuke touches her inappropriately. Yusuke says it hurts more than Kwuabara's punches.
* BelligerentSexualTension: Her and Yusuke.
* BrainyBrunette: The invesigator from spirit world says "Her marks are next to perfect."
* BrownEyes
* ChildhoodFriendRomance: With Yusuke.
* CurtainsMatchTheWindow
* DistressedDamsel: Not her fault, as it's a consequence of having no magic or spiritual powers.
* GirlNextDoor
* HeroicBSOD: Has a pretty big one when Yusuke gets the tar beaten out of him by Younger Toguro.
* IWishedYouWereDead: After being irritated by Yusuke yet again, she furiously snaps "Why don't you just ''die''?!" Shortly after, Yusuke performs his HeroicSacrifice to save a kid, and Keiko's resultant breakdown is part of what convinces him to work his way back.
* MoralityPet: To Yusuke. Seeing him caring for, and being bossed around by, her shows he's a JerkWithAHeartOfGold.
* {{Muggle}}: Keiko and Atsuko are the only characters listed here without any kind of supernatural powers.
* OfficialCouple: With Yusuke since his revival more or less. Cemented at the end.
* PluckyGirl: Hiei's Shadow Sword, insect-controlled humans, the Dark Tournament...she's been able to handle it all pretty nicely. Borders on BadAssNormal sometimes (the girl's willing to ''douse herself with water and go through fire'' to rescue Yusuke's body!)
* {{Shorttank}}: Even if she ''is'' fond of wearing dresses.
* SpellMyNameWithAnS: Television closed captions for the English dub spell her name as "Kayko".
* TraumaticHaircut: Averted. Getting parts of her hair singed off after rescuing Yusuke from a fire leads to no angst on her part.
* {{Tsundere}}: Type A ''towards Yuusuke big time''... even moreso in the manga.

[[WMG: Koenma]]
'''Species:''' Spirit Being\\
'''Main Power:''' Shapeshifting / Ma Fū Kan]

-->''Actually, I'm proud to say that in addition to knowing the greatest secrets of the universe, I am also quite potty-trained.''

->Voiced by: MayumiTanaka (JP), Sean Michael Teague (EN)

Chief administrator of the Spirit World and son of King Yama, Koenma resurrects Yusuke and becomes his employer.
* BadBoss: Played for laughs as he treats the narrator like dirt.
* BerserkButton: Being laughed off for resembling a toddler.
* BigGood: He is Yusuke's boss and the administrator of the Spirit World.
* {{Bishonen}}: In his adult form.
* ChekhovsGun: [[spoiler: His pacifier is a device that creates a barrier strong enough to hold S-Class demons.]]
** ChekhovsGunman: The Chapter Black Saga forces him out of the sidelines, and into the front field for the first time.
* CrossdressingVoices: Voiced by Mrs. Mayumi Tanaka in the original Japanese. Is also often voiced by female actresses in the dubs. In the Latin American dub, Child!Koenma was voiced by a woman; older!Koenma, by a man, and he's also voiced by a man in the English dub.
** Averted in the English dub, much to Sean Michael Teague's vindication. He talks on the commentary track about how his voice is so high that he's constantly being mistaken for a woman at drive-throughs, so getting a job ''because'' he has a higher-pitched voice was great.
* DeadpanSnarker: In his older form.
* FailureKnight: [[spoiler: Is extremely guilt-ridden from his involvement and appointment of Sensui. Enough for him to [[LovableCoward face him personally]], and betray his own father.]]
* KingOfAllCosmos: More like prince, but still he's a toddler.
* [[SheIsAllGrownUp He Is All Grown Up]] / OlderAlterEgo: Has a ''very'' bishounen adult form.
* ImmortalImmaturity: More in the anime than the manga, and usually when he's in his baby form.
* MrExposition: Particularly in the anime, where he has a video screen that lets him see everything and a clueless assistant who needs things spelled out to him.
* NonActionGuy: The Koenmatron jetpack is his solution to fighting.
* OralFixation: His pacifier. Even as his [[OlderAlterEgo Older and]] SexierAlterEgo, he keeps the pacifier.
* RageAgainstTheHeavens: [[spoiler: Behind the scenes, during the Demon World Unification Tournament, Koenma impeached and overthrew his father for the crimes of manipulating Demons to cause crimes in Human World for centuries.]]
* ReallySevenHundredYearsOld: Is exactly 700 years old, and appears to be a toddler. He can transform into a bishonen teen form for a few minutes at a time... but doesn't remove his pacifier when he does so.
** Stays in teenage form continuously later in the series when it gets more serious. Eventually the pacifier is [[ChekhovsGun revealed to be a device to store energy]]. He keeps the the pacifier in his mouth even after using up its stored energy, presumably because that's how he recharges it.
* SexierAlterEgo: Koenma (usually in the form of an infant with a pacifier) is able to take on an older, more {{bishounen}} appearance.
* ShoutOut: He is disguised as [[spoiler: [[Franchise/SailorMoon Tuxedo Mask]]]] at the Makai Tournament, probably because Togashi and Takeuchi were dating at the time.
* SpoiledBrat: A bit in his baby form.

[[WMG: Genkai]]
'''Species:''' Human Psychic\\
'''Main Power:''' Spirit Wave]

-->''I fight to get what I need, and I kill whoever gets in my way. I always have.''

->Voiced by: HisakoKyoda (Older) and MegumiHayashibara (Younger) (JP), Linda Young (EN)

A legendary human psychic that holds a tournament to choose an apprentice to pass on her power to in her old age. With Yusuke's victory, she becomes his mentor, determined to beat skill into him even if he doesn't want it. Unknown to everyone (though not above suspicion), she's also the fifth masked fighter for Team Urameshi during the Dark Tournament. Has something of an ''interesting'' past with the younger Toguro brother.
* ActionGirl: She is still one of these [[NeverMessWithGranny as a 70+ year-old woman]], and, when she was younger, [[spoiler: she helped Team Toguro with the Dark Tournament, her being the only girl on that team]].
* {{Affectionate Nickname}}s: Yusuke calls her an assortment of names ranging from 'old hag' to 'Grandma'. She, in turn, calls him 'dimwit', among other things.
* [[spoiler:BackFromTheDead]]
* BadAss
* BroughtDownToNormal: [[spoiler:The ultimate secret of the Spirit Wave is the Spirit Wave Orb, which she has to pass down to her apprentice. This makes him stronger while it makes her roughly 90% weaker]].
** BroughtDownToBadass: Yet the lil 'ol hag still manages to hold her own quite well against Doctor's territory. Prior to that, she also took out [[spoiler:Suzuki]] and [[spoiler:Shishiwakamaru]], two C-class demons, with little effort, as well as became the first character on-screen to actually manage to [[spoiler:injure Younger Toguro]].
* CoolOldLady
* DeadpanSnarker: She will say what's on her mind and she isn't afraid to hold back. Oh, and if you don't like it/can't handle it - too bad, she'll kick your ass too.
* GamerChick: Because she doesn't have much to do when she's not training besides playing some arcade game she owns. Really.
** [[spoiler:ChekhovsGun: It becomes very useful against one of Sensui's men who can [[IKnowMortalKombat manifest video games into reality]].]]
--> ''Genkai'': "What? You think I've been playing Solitaire for the past 50 years?"
* HealingHands: Though she doesn't use them often.
* HonestAdvisor: See DeadpanSnarker.
* HugeGuyTinyGirl: With her old friend [[spoiler: Younger Toguro]].
* IWasQuiteALooker: Was [[CuteBruiser VERY cute]] when young. [[spoiler: Her choosing to be old rather than [[DealWithTheDevil become a demon like Toguro]] is what drove him to kill her.]]
* [[spoiler:KilledOffForReal: In the manga, she already passed away at the start of the last chapter. She died after Team Yusuke's last mission at the Gates of Judgment hostage situation.]]
* [[spoiler: LittleDeadRidingHood: Was killed by Younger Toguro in her usual red attire. She recovered]]
* [[spoiler:MeaningfulFuneral: In the manga]]
* MeaningfulName: Genkai generally means "limit" in Japanese. Has quite a few meanings in context of the show, huh? It's a homonym too; her name is written with the kanji for "illusion" and "sea"- "sea of illusion", which is also meaningful as she's an OldMaster with a lot of secrets.
* {{Miniature Senior Citizen|s}}: Although she is seen in flashbacks to have always been that height.
* NeverMessWithGranny: As someone who is a former champion of the Dark Tournament, her fighting skill should be without question. That doesn't stop glory-seeking demons from trying to fight her...
* NotSoStoic: Is harsh, disparaging, and domineering to Yusuke to a fault, but almost has an HeroicBSOD [[spoiler: when he dies in the Chapter Black saga.]]
** Also, [[spoiler: she yells at Toguro-ototo when he's literally about to go to Hell.]]
*** [[spoiler: And when he continues to deny she is the same person that fought alongside him 50 years ago, she is VERY UPSET.]]
* TheObiWan: [[spoiler: Toguro kills her to make Yusuke stronger.]]
** [[spoiler: She's revived later by Koenma]]
* OldMaster: The "just wants a break" version, and badass grandma.
* PaperThinDisguise: Doubly subverted. [[spoiler: Her disguise is her usual outfit with a head covering bandage. Underneath is her younger appearance.]]
* PintSizedPowerhouse: She's barely taller then Hiei. In her first episode, she knocks two rude and huge men into a wall just by blinking a wave of energy at them. Be polite to your elders.
* ProgressivelyPrettier: When she first appeared, she was downright toad-like, with yellowish skin and gigantic eyelids. As her role expanded, she started letting her hair down, grew eyebrows (??), and dropped a few obvious wrinkles. She still looks worn down and ragged, but you can tell that she was once very pretty.
* RenownedSelectiveMentor: Holds a tournament to determine her successor. However, she also points out that she doesn't consider morality a factor when selecting a successor, and part of Yusuke's entering is so that Rando will not receive her techniques.
* ShesAManInJapan: In the Philippines actually.
* SinkOrSwimMentor: "Use your spirit energy to float above the spike."
* SternTeacher: Very stern.
* TrainingFromHell: For Yusuke and herself. [[spoiler: And the Six Fighters, in the Three Kings arc.]]
* TricksterMentor: Sometimes, as part of his TrainingFromHell
* YouGottaHaveBlueHair: Pink hair, which grayed over time.
* [[spoiler: TheSixthRanger.]]

[[WMG: Yukina]]
'''Species:''' Demon\\
'''Main Power:''' Ice Manipulation]

-->''Go Kuwabara! You can do it!''

->Voiced by: Creator/YuriShiratori (JP), Jessica Dismuke (EN)

Hiei's twin sister, a fact lost only on Kuwabara and Yukina herself. An ice demon, and the object of Kuwabara's affections. She was kidnapped and kept imprisoned for a time by Tarukane because her tears, which transform into jewels, fetch a high price on the black market.
* AnIcePerson: She's a lot nicer then Seiryuu at least.
* BewareOfTheNiceOnes: She once told Hiei her ''real'' reason for searching her brother: [[spoiler: reminding him his promise to kill all the Ice Maidens and lead him where they lived]].
* BreakTheCutie: She experiences this briefly after watching her only two friends, a pair of bluebirds, get murdered in cold blood.
* CutenessProximity: Her very ''appearance'' is enough to turn anyone into a doting big-brother and CoolBigSis who wants to hug her all day long.
* DamselInDistress: A defiantly dignified one, facing torture with as much dignity as she can unless ''others'' are threatened/tortured/killed in front of her.
** Which [[FridgeHorror hits you like a sack of bricks]] when you think of how ''long'' she has been tortured until the point of desensitization.
* FriendToAllLivingThings: Portrayed this way in her first appearances. The manga has an off-hand mention of the birds being Reikai messengers, however, and later, one of Hiei's [[WholeEpisodeFlashback Whole Episode Flashbacks]] has her make an interesting statement...which makes her a [[SubvertedTrope subversion]] of the trope, if anything.
* HealingHands: But not TheMedic. Her powers are good, but she doesn't appear often enough for that.
* HugeGuyTinyGirl: With Kazuma who is easily twice her size.
* ImTakingHerHomeWithMe: Kuwabara's ''first'' reaction upon seeing her in Koenma's mission video, and just about every ''good'' person in the cast when they meet her for the first time. By the end of the series [[spoiler: Kuwabara's family ''does'' take her home, whether as a little sister or as Kazuma's wife is left uncertain.]]
* ImpliedLoveInterest: Of Kuwabara by the end of the series.
* TheIngenue: Kind, innocent, gentle, etc.
* MercyKill: Seems to want this to happen to the Ice Maiden society.
-->'''Yukina:''' "If survival means becoming as cold as ice... then I don't see the point."
* NiceGirl
* [[spoiler:MaybeEverAfter]]: [[spoiler:With Kuwabara.]]
* {{Protectorate}}: Of Kuwabara. Raising a hand to her is a very good way to cause Kuwabara's instant UnstoppableRage.
* RedEyesTakeWarning: Subverted. She has deep red eyes yet she's anything BUT evil. [[spoiler: Then again, she's searching her brother to have him commit a genocide...]]
* RedStringOfFate: With Kuwabara.
* SeparatedAtBirth: With [[spoiler: Hiei]].
* [[BodyToJewel Tears to Jewel]]: Her tears become valuable jewels, which has people trying to make her cry through [[ColdBloodedTorture incredible cruelty]].
* WillTheyOrWontThey: Her and Kuwabara. And the finale [[spoiler: [[StatusQuoIsGod keeps the status quo]] even though there are some hints that Yukina [[MaybeEverAfter just might reciprocate]].]]
* WomanInWhite
* YamatoNadeshiko: In both appearance (long hair, kimono, moderate height) and personality (dignified, strong willed, polite, loving) and [[spoiler: just might have become Kuwabara's wife at the end.]]
* [[YouGottaHaveBlueHair You Gotta Have Sea Green Hair]]

[[WMG: Atsuko Urameshi]]
'''Species:''' Human\\
'''Main Power:''' None]

-->''No one gave you permission to die! You got hit by a car, strong people live through that!''

->Voiced by: YokoSoumi (JP), Meredith [=McCoy=] (EN)

Yusuke's alcoholic mother, unaware of his Spirit Detective job.
* AbsurdlyYouthfulMother: Was only 15 when Yusuke was born.
* AlcoholicParent
* AmicableExes: With Yusuke's dad.
* AwLookTheyReallyDoLoveEachOther: She may not be the most responsible parent, but she genuinely cares for Yusuke.
* DemotedToExtra: She kinda disappears after the anime's Spirit Detective arc. Notably, when Keiko, Botan and Shizuru are discussing the Dark Tournament in the anime, Atsuko is passed out drunk. In the manga, the scene is never shown, but all four show up there together.
* DoesNotLikeShoes: She never appears to wear any in the anime. Subverted in the manga as she also wears her [[BadassInANiceSuit business attire]] from time to time.
* DragonLady: Not shown in the anime, but she seemed to have ties with Yakuza. She and her group threatened the school's principal to let Yusuke come back to school after he came back to life. She also got Yusuke set up a business of his own through her connections at the end of the manga.
* HardDrinkingPartyGirl: She often draws others in.
* {{Muggle}}
* OneOfTheBoys: Her pals outside of Yusuke's circle in the manga are men.
* StacysMom: Kuwabara's gang certainly seemed to think she is a hot mom.

[[WMG: Shizuru Kuwabara]]
'''Species:''' Human\\
'''Main Power:''' None]

-->''C'mon kid, I think you're way past your sympathy limit.''

->Voiced by: Creator/AiOrikasa (JP), Kasey Buckley (EN)

Kuwabara's DeadpanSnarker sister, even more spiritually aware than him.
* ActionSurvivor
* AllGirlsWantBadBoys: Her and [[CorruptCorporateExecutive Sakyo]] in the anime. Thought she doesn't seem to have many illusions about him turning to the side of good, she ''does'' listen to his really creepy backstory and show him far more compassion than he deserves. Could be [[SubvertedTrope subverted]] due to just being his [[{{Bishonen}} looks]].
* [[AloofBigBrother Aloof Big Sister]]
* [[BigBrotherBully Big Sister Bully]]: She's sometimes abusive towards her brother.
* CoolBigSis: actually Kuwabara Kazuma's older sister, who seems to consider it her job to keep the younger (acting?) girls safe and upbeat.
* CurtainsMatchTheWindow
* DeadpanSnarker
* [[EducationMama Education Big Sister]]: In the final arc, puts pressure on Kuwabara to study, which results in him getting into a good high school, albeit barely.
* ItRunsInTheFamily: Has a high spiritual awareness like her brother.
* {{Jerkass}}: A lesser version.
* PsychicPowers: Is much more powerfully clairvoyant and can actually see ghosts.
* SmokingIsCool: She even puts her cigarette out on an apparition's tongue to shut him up.
* SugarAndIcePersonality
* TragicKeepsake: [[spoiler: Sakyo's lighter]].

[[WMG: George Saotome]]
'''Species:''' Spirit Being\\
'''Main Power:''' None]

-->''I need a new job…''

->Voiced by: Creator/TomomichiNishimura (JP), Creator/KentWilliams (EN)

Koenma's ogre assistant, often blamed and bullied by him.
* ButtMonkey: He gets abused by Koenma even when he doesn't do anything.
** IronButtMonkey
* CanonForeigner: Doesn't appear in the manga, where his function is usually served by Botan or Ayame.
* [[spoiler: NarratorAllAlong: It is discovered in the last episodes, although hinted at shortly before, that he was the narrator of the show- since it is revealed that the show itself is the records of the protagonists' adventures that Koenma kept (hence the title, which, while using the original Japanese name, is nonetheless translated by Creator/{{Funimation}} as "Ghost Files").]]
* OnlyKnownByTheirNickname / NoNameGiven: The dub credits him as "Blue Ogre" up until Chapter Black, and Koenma addresses him as "Ogre." The Japanese version reveals his name during or near the end of the Dark Tournament, and Koenma just calls him "[[HeyYou you]]" before that.
* OnlySaneMan: ''Painfully'' obvious...
* TheWatson: He exists purely for Koenma to abuse and explain things to.


'''Species:''' Demon\\
'''Main Power:''' Ice Manipulation]

-->''The Shinobi have done their job for centuries, and done it well. But in recent years, we have caught glimpses of the outside world, and asked; 'Why not us?' Have we not earned the privilege others take for free?''

->Voiced by: YasunoriMatsumoto (JP), Daniel Katzuk (EN)

Toya is the ice master of the shinobi of the Spirit World. During the fight for control of the Makai, Toya is one of the demons that Kurama trains to fight for Yomi, though they eventually all disband to fight individually in the Makai tournament.
* TheAce: Considered to be the greatest ice master alive.
* ADayInTheLimeLight
* BadAss: ''Very'' tough customer.
* DoesNotLikeShoes
* FriendlyEnemy: In his fight with Kurama.
* AnIcePerson: A demon ninja with mastery over ice. When he went under [[OldMaster Genkai]] for some TrainingFromHell, he became powerful enough to freeze a battlefield.
* IcyBlueEyes
* LetsFightLikeGentlemen: In the first tournament he openly objects to his team leader's dirty tactics.
* MonochromaticEyes
* {{Ninja}}
* YouGottaHaveBlueHair: Ice blue hair with pale green bangs
** MulticoloredHair

'''Species:''' Demon\\
'''Main Power:''' Wind Manipulation]

-->''I thought I was crazy, Urameshi, but you take the prize!''

->Voiced by: Creator/KappeiYamaguchi (JP), Creator/JerryJewell (EN)

Jin is a demon with mastery over the wind. This grants him the power to fly at great speeds. His signature move is to spin his forearm at high speed, creating a tornado around it, making his punches more powerful, even causing damage when he misses. He enjoys his battles, especially when he has a worthy opponent. He states that when he gets excited about a fight his ears twitch. During the fight for control of the Demon World, Jin is one of the demons that Kurama trains to fight for Yomi, though they disband to fight individually in the Demon World tournament.
* ADayInTheLimeLight
* BadAss
* BlowYouAway
* BloodKnight: Jin loves to fight just as much as Yusuke.
* BoisterousBruiser
* CuteLittleFangs: See [[http://quizilla.teennick.com/user_images/S/SH/SHU/shuichisgirlfriend/1165021852_8screencap.jpg here]]
* DoesNotLikeShoes
* FieryRedhead
* {{Keet}}: This is not helped by the fact that he has the same [[Creator/KappeiYamaguchi Japanese voice actor as Ryuichi Sakuma]].
* {{Ninja}}
* FriendlyEnemy: ''Very!'' He and Yusuke get along remarkably well!
* WorthyOpponent: Views Yusuke as one.

'''Species:''' Demon\\
'''Main Power:''' Drunken Fist]

-->''Right! Before we get this thing started I just want to say I'm a great guy and the only thing I suck at is Rock, Paper, Scissors!''

->Voiced by: NorioWakamoto (JP), Creator/KentWilliams (EN)

Chu is the strongest fighter and leader of team Jolly Devil Six, but ends up as the team alternate after losing at Jan-ken-pon. Chu specializes in the "Drunken Fist", which fuses the alcohol he drinks with his aura. During the fight for control of the Makai, Chu is one of the demons that Kurama trains to fight for Yomi, though they eventually all disband to fight individually in the Makai tournament. At the end of the manga, he begins training with, and falls for, Natsume, the female demon who defeated him in the Makai tournament.
* AddictionPowered: The drunker he gets, the stronger he becomes.
* AuthorityEqualsAsskicking: Zig-zagged, it seemed Zeru, the proxy leader was the real threat, however the only reason Chu wasn't in the roster initially is that he lost at RockPaperScissors. He soon proves his strength soon enough.
* BoisterousBruiser: He's by far the tallest guy Yusuke hangs out with, he [[TheAlcoholic drinks like a fish]] and only becomes that much stronger when he does it. Helped by [[Creator/NorioWakamoto who voiced him as well]].
* BloodKnight: When Yusuke tells him he wants to see if he has more than his drunken fist, he gets very interested
* CrouchingMoronHiddenBadass: He shows up tripping over everything, acting dumbly and lazily, and looking like crap. Boy, does he ever turn out to be ''total badass''. It's pointed out soon afterward that he's only the "alternate" because he lost in rock paper scissors.
* DrunkenMaster: Became more dangerous after taking a swig of Ogre Killer. Taken to whole new levels when his most powerful attack actually involves mixing his energy with alcohol to make an energy ball powerful enough that two shots of Yusuke's Spirit Gun couldn't equal it. The first shot weakened the attack and the second shot burst through it, punching a hole in the middle, but not stopping it. Even better, he has a special kind of alcohol that... well... induces vomiting. Once he's emptied his stomach, he gets drunk even faster, which summons more of his demonic energy for him to use. (Tequila?)
* HandsomeLech
* HeelFaceTurn
* LargeHam: What did you expect of NorioWakamoto? And surprisingly enough, Kent Williams manages to up the ante with a hammy Australian accent!
* LoveAtFirstPunch: With [[IceQueen Natsume]].
* TheAce: To his team
** WildCard: He appears without any foreshadowing, and gives Yusuke who had [[TookALevelInBadass taken training]] what was intended to be a CurbStompBattle and change it into an equal fight. Even their sponsor lampshades it.
* WorthyOpponent: Views Yusuke as one.

'''Species:''' Demon\\
'''Main Power:''' Serpent Yo-Yos]

-->''I know a fun new game. I'll throw my yo-yos and you try to stay alive.''

->Voiced by: Yoshiko Kondo (JP), Kimberly Grant (EN)

Rinku is a young demon who uses yo-yos to attack. Rinku is childish and playful, and often annoys those around him. He controls his yo-yos by channeling his aura through the strings. During the fight for control of the Makai, Rinku is one of the demons that Kurama trains to fight for Yomi, though they eventually all disband to fight individually in the Makai tournament. At the end of the manga, he becomes stricken with Sasuga, a female demon who defeated him in the Makai Tournament, and it is hinted that they are in a relationship together.
* CreepyChild: Very creepy, at first.
** It faded away with time. After befriending Team Urameshi, he stopped the psychotic grins.
* CuteIsEvil
* EnfanteTerrible
* GreenEyes
* HeelFaceTurn
* LikesOlderWomen: Though its hard to tell his age, he did have a crush on a taller and teenage looking demon.
* NiceHat
* KillerYoyo: Rinku can control four yoyos in each hand and each one attacks independently of the other and obey his will. After his TrainingfromHell, he can use eight yoyos.

'''Species:''' Demon\\
'''Main Power:''' Shapeshifting / Banshee Shriek]

-->''Well, I think the end of the world would have to make a bit of noise.''

->Voiced by: Creator/ToshiyukiMorikawa (JP), Creator/ChristopherBevins (EN)

Shishiwakamaru is a tiny imp demon who can transform into a full human appearance. He is a swordsman who seeks to make himself famous. Suzuki gives him the Sword of Trials, a sword hilt that changes into whatever weapon suits the wielder. For Shishi it becomes the Banshee Shriek, a sword which channels the souls of the dead and materializes them to devour his opponent. During the fight for control of the Makai, Shishi is one of the demons that Kurama trains to fight for Yomi, though they eventually all disband to fight individually in the Makai tournament.
* BigBadWannabe: For a minute there, it really looked like he'd be the next tough opponent. ...''He wasn't.''
* HeelFaceTurn: Once retconned into surviving his battle with Genkai
* ItsAllAboutMe: He sort of acts like a celebrity and is obsessed with fame.
* MakeMeWannaShout: His sound's wailing can steal the souls of weaker beings who hear the sound and his attacks are based around sound in general.
* {{Retcon}}: Shishiwakamaru was clearly meant to be dead after Genkai defeats him. In the original Japanese version, Genkai even refers to him as "the late Shishiwakamaru" in her battle with Suzuki. But in the final TournamentArc, he's inexplicably alive and a good guy. One wonders if his real-life fangirls had some sort of influence on this decision.
* {{Samurai}}: Shishiwakamaru, patterned after the legendary hero [[http://en.wikipedia.org/wiki/Minamoto_no_Yoshitsune Minamoto-no-Yoshitsune, aka Ushiwakamaru]], the samurai that was said to originate the term {{Bishonen}}.
* SleepModeSize: Maybe. When he reappears to train with Kurama, he's in an inexplicable bird-like form small enough to fit on Suzuki's shoulder. This form and its relative power/use compared to his bishie form are neither commented on nor explained.
* SmugSnake
* SplitPersonality: Shishiwakamaru fluxuates between a smug warrior and a bloodthristy berserker.
* TeamPrimaDonna: To both Team Uraotogi and the Six Fighters.
* VillainousBreakdown: Shishiwakamaru goes ''ballistic'' once he realizes Genkai has the upper hand in their fight.

!!Yu Kaito
'''Species:''' Human Psychic\\
'''Main Power:''' Taboo]

-->''I drew this by hand. And yes. It IS to scale.''

->Voiced by: Creator/IsseiFutamata (JP), Jakie Cabe (EN)

Yu Kaito is a human who develops superhuman powers as a result of the demon plane hole opened by Sensui. He is a student at Meioh Private Academy where he constantly attempts to outdo Kurama for top grades. He is a master of the written word, having written several books and enjoys word puzzles.

His ability is "Taboo" which allows him to create word games that those within his territory must adhere to or their soul will be extracted from their body. While testing the limits of his power, Kaito breaks his Taboo and has his own soul sucked from his body, prompting Kido and Yanagisawa to consult Genkai to help him and explain their new powers.

In the manga, his last appearance shows him spending his day off mostly playing video games and writing.
* BadassPacifist: ''Literally''. His power completely bans violence of any kind, and the only way to beat him is to outsmart him in word games. Considering just how freaking intelligent the guy is, ''good luck.''
* BadassBookworm
* HoistByHisOwnPetard: His taboo power also applies to him.
* InsufferableGenius: At first.
* MeaningfulName: Yu means ghost and Kaito means thief. One can only wonder why he steals the souls of up to three of our main characters.
* TheProblemWithPenIsland: If he makes a word taboo, anyone who says the syllables for it in succession loses their soul, regardless of whether it's two words formed together, such as "eac'''h''' '''ot'''her" for "hot".
* TheRival: Academically, to Kurama.
* TheScottishTrope, WordsCanBreakMyBones: If you say the Taboo word, you lose your soul.
* SecretKeeper: [[spoiler: He is the only human who knows Kurama's whereabouts in the last arc.]]
* RealityWarper: His territory bans violence and imposes linguistical taboos which must be cleared.

!!Asato Kido

'''Main Power:''' Shadow]

-->''You've made a lot of friends and enemies, Yusuke, and now we're doing one of them a special favor.''

->Voiced by: Creator/TakehitoKoyasu (JP), Iman Nazemzadeh (EN)

Asato Kido is a human who develops superhuman powers as a result of the demon plane hole opened by Sensui. His ability, "Shadow", allows him to step on someone's shadow and incapacitate them. Along with Yu Kaito and Yanagisawa he seeks the aid of Genkai when his powers appear. It is shown that he also has limited control over his own shadow, using it to spell out his attackers name after he is paralyzed by Doctor. In his final manga appearance, Kido is shown to have been stood up by his date in a cinema while the narration says he is far too forgiving.

* RedemptionDemotion: Beaten up by Murota and paralyzed by Doctor within two episodes. (Not that he was really so bad before...)
* CouldntFindAPen: Uses his Shadow for this to tell Yusuke that Kamiya is the Doctor.
* CurbStompBattle: As Genkai [[DeadpanSnarker so kindly puts it]], if Yusuke's fight with Kaito was for real, he would've been deader than dead.
** Also receives one from Murota and one from Doctor.
* KnightOfCerebus: Two-ways. His appearance marks the point when the series takes a ''much'' darker and more mature turn, and when Yusuke comes to the realization that brawn and power alone hardly wins every fight.
* NiceGuy: Despite appearing to be a tough [[FaceOfAThug thug]], he's actually the most polite of his group.
* PutOnABus: Spends most of the Chapter Black saga offscreen in the hospital.
** TheBusCameBack: The doctor likely healed him.
* ShadowPin: Could paralyze people by stepping on their shadows, and managed to hand Yusuke an embarassing defeat by doing just that. He can also control his own shadow independently of the rest of his body.

->Voiced by: Creator/MitsuakiMadono (JP), Creator/TravisWillingham (EN)

Mitsunari Yanagisawa is a human who develops superhuman powers as a result of the demon plane hole opened by Sensui. His power is "Copy" which allows him to copy the appearance, memories, attributes, abilities, and spirit print of anyone he touches. In his last appearance in the manga, he is too shy to ask an attractive girl out, and it is revealed that ten years later, he marries the girl that tries to cheer him up.

* DareToBeBadass: During Yusuke's fight with Doctor he [[spoiler: manages to burn Doctor with chemicals.]]
* EightiesHair: That's some epic hair, man.
* MasterOfDisguise

Murota is a human who develops physic powers as a result of the demon plane hole opened by Sensui. He is recruited by Yusuke, Genkai, Kido and Yana when they arrive in Mushiyori City, using his abilities for Team Urameshi to gather information on the Sensui Seven. His power is Wiretap, which allows him to read the minds of anyone in a 30 mile radius. [[spoiler: He's eaten by Gourmet after Kuwabara was captured]]

* BoxingBattler: Is a boxer. His mind reading power gives him a distinct advantage in fights, albeit not nearly enough to beat Yusuke.

Raizen's second-in-command. He first appears to offer Yusuke the chance to go back to demon world to train and take over Raizen's position if he dies.

'''Main Power:''' Has 99 Different Powers]

-->''This has always been the hardest part, choosing which technique to destroy my opponent.''

->Voiced by: Creator/YouInoue (JP), Creator/EricVale (EN)

Rando is a demon who participated in Genkai's tournament and serves as the main antagonist in Yusuke's second case. He has killed 99 masters and copied their techniques. He disguises himself as Shaolin monk during Genkai's tournament so as not to draw attention to himself. He had planned to win the tournament and make Genkai's Spirit Wave the 100th technique in his arsenal.
* AmbitionIsEvil
* ArcVillain
* ArrogantKungFuGuy
* AwesomeButImpractical: His Shrinking Curse is basically an instant win if it hits, but requires an absurdly long chant to use and can be defeated by earplugs.
** Not just defeated, but deflected back. If the technique is used with no one else around the hear the chant, the spell is cast on the user instead.
* CrossdressingVoices: In the Japanese version.
* EvilRedhead
* FacialMarkings
* FatalFlaw: He is so obsessed with the power of techniques, he doesn't bother to learn their weaknesses and how they can backfire.
* HoistByHisOwnPetard: The Shrinking curse backfires on him.

!!''The Four Saint Beasts''

The Four Beasts are four demons who rule a part of the Underworld called City of Apparitions and the antagonists for Yusuke's third case. The beasts share their names with the four symbols of Chinese astrology. In the anime adaptation they are known as the Saint Beasts.
* KnightOfCerebus: The first enemies that have [[spoiler: [[YouHaveOutlivedYourUsefulness their own teammates killed]]]], and to be killed through [[TheDeterminator determination]] rather then dumb luck.
* BishonenLine: The stronger the Beast, the more human they are.
* ElementalPowers: Genbu [[DishingOutDirt can control the stones that make up his body]], Seiryuu [[AnIcePerson can manipulate ice]] and Suzaku [[ShockAndAwe is able to use lightning]]. Byakko is just [[DarkChick a tiger man who can fire beams from his mouth and create creatures from his hair]].
* TheFourGods: Each of them have an obvious design theme that makes them related to that specific god.
* FourIsDeath

'''Species:''' Demon\\
'''Main Power:''' Stone Body / Stone Manipulation]

-->''Why don't you all attack me at once? Then the last one left won't be lonely.''

->Voiced by: Yutaka Shimaka (JP), Chris Forbis (EN)

A rock demon with the power to move through stone as though it were part of his body.
* TheFourGods: With his shell and reptilian features, he's like demon throwback to gargoyle turtle man.
* TheBrute: Fights with one trick through brute force.
* DishingOutDirt: More like made of dirt.
** ElementalEmbodiment: He's more of a golem
* HomeFieldAdvantage: The first of the 4 Sacred Beasts, Genbu, can use his powers over earth to meld with the stone that composes the castle and move freely through it.
* MonstrosityEqualsWeakness: Looks like a turtle Kaju with a troll face, but had the second swiftest defeat,
* PullingThemselvesTogether: Does this, but epically backfires in a real funny way.
* RockMonster: He's composed of rock, and can melt into any rock surface. He can also control his rock body at will, and is fond of attacking by turning his body into a swarm of rocks and flying towards his opponent.
* SmugSnake: Believes he's going to win and that his power has no flaws, [[AintTooProudToBeg leading him to plead with his opponent not to kill him]].
* TagAlongKid: A sinister subversion. The reason the other Saint Beasts tolerate him is that he can communicate with the demons, they would've been the Three Saint Beasts a long time ago if that wasn't the case.

'''Species:''' Demon\\
'''Main Power:''' Energy Absorbtion / Summon Beasts / Tiger Scream]

-->''Humans! I will rip you apart and eat you myself!''

->Voiced by: TakeshiWatabe (JP), Andrew Chandler (EN)

An anthropomorphic white tiger who can turn pieces of his hair into lesser beasts, absorb aura energy and fire sonic blasts from his mouth.
* [[spoiler: AlasPoorVillain: The story takes a moment to focus on Byakko's shock and horror when he is betrayed and executed by Seiryuu for failing to beat his opponent. This is inspite of being of an arrogant man-eating demon.]]
* TheFourGods: Represents the White Tiger
* [[spoiler: EtTuBrute: He is genuinely shocked when Seiryu decides to kill him for his failures]]
* EvilCounterpart: To Kuwabara
* EvilGenius: See GeniusBruiser below.
* FeedItWithFire: He can absorb spirit energy, becoming bigger in the process.
* GeniusBruiser: Although he is just [[TheBrute muscle]] like Genbu, he employs a lot more moves and wit.
* MadeOfIron: He survives ''falling into lava'', but is grievously injured
* MakeMeWannaShout: His "Tiger Scream" disintegrates anything it hits.
* MonstrosityEqualsWeakness: Averted in that he's tougher than Seiryuu.
* FairPlayVillain: He's straightforward compared to [[DirtyCoward hide and seek]] Genbu, [[YouHaveOutlivedYourUsefulness ruthless]] Seiryuu and [[{{Sadist}} wicked]] Suzaku.
* PantheraAwesome: A white tiger man.
** PettingZooPeople: a tiger man
* RasputinianDeath: Falls from a great height, falls from a great height ''into lava'', but is then ultimately only killed by being frozen and [[LiterallyShatteredLives shattered]]
* SmugSuper: He views himself highly with justified reason, seeing that he has a powerful MakeMeWannaShout attack that is legendary in the Demon World, and due to this reason, he didn't even try to come and face Kuwabara, choosing to have his hairs face him instead.
* SympathyForTheDevil: You must be doing something right, when [[{{Jerkass}} Hiei]] feels sorry for you.

'''Species:''' Demon\\

->Voiced by: Mitsuo Senda (JP), JustinCook (EN)

A demon with enhanced speed and control over ice.
* ArrogantKungFuGuy: Even looks like a martial artist.
* EvilCounterpart: To Hiei.
* TheFourGods: He'd be the dragon...though he's just a big blue skinned man with a dragon outfit. ''YuYuHakushoAbridged'' so LampShades this.
* AnIcePerson: Fragile enough to the point that [[OneHitKill one blow is enough to defeat]], and one can do it through ice punches
* CurbStompBattle: Cut into many pieces by Hiei almost instantly.
* TheDragon: Which is fitting.
* KickTheDog:[[spoiler: Killing Byakko for failing, the fact that he tried asking for help and genuinely shocked at the betrayal makes it worse]]
* [[spoiler: [[SingleStrokeBattle Sixteen Stroke Battle]]: Hiei kills him in 16 slices]]

'''Main Power:''' Lightning Manipulation / Prism of Seven]

-->''You should feel most fortunate, Yusuke. Not everyone's girlfriend gets to star in a horror movie.''

->Voiced by: Creator/NobuoTobita (JP), Creator/JerryJewell (EN)

The leader of the Four Beasts. A demon who uses lightning to attack, he is able to split himself into seven separate, yet equally powerful bodies, and can endlessly regenerate his power by reabsorbing the copies.
* TheFourGods: He'd be the Phoenix, especially since he can revive himself mutliple times and has a bird for a [[CampStraight companion]].
* {{Badass}}: Despite what a bastard he is, Suzuku is undeniably badass. He made Yusuke's training and new techniques look like child's play for most of their fight.
* BiggerBad: Of the Spirit Detective saga.
* BigBad: Of the Saint Beasts Saga.
* {{Bishonen}}: Fits with the BishonenLine theme that the Saint Beasts are going for.
* ColdBloodedTorture: Suzaku is a massive sadist who sits on his chair while his clones electrocute Yusuke, six on one.
* DoppelgangerAttack: Like mentioned above, seven clones, each just as strong as him.
* FauxAffablyEvil: Is infinitely more pleasant, polite, and serene than his allies. However, this politeness and calm persona is a facade to mask his utterly sadistic love of tormenting and [[ShockAndAwe torturing]] others for the sheer, near childlike glee of it all. Such as how he mercilessly tortures Yusuke and forces him to watch while his [[BrainWashedAndCrazy mind controlled minions]] were about to kill [[LoveInterests Keiko]] and Botan; all the while enjoying himself like he is watching his [[GenreSavvy favorite horror film.]]
* GenreSavvy: His scheme (especially regarding Keiko) is set up like a B-grade horror movie. That isn't lost on him in the slightest.
** DangerouslyGenreSavvy
* ManipulativeBastard: Figuratively to the other Saint Beasts, and literally with his flute.
** And emotionally towards Yusuke. Yusuke even says "You think you can ''control'' me, don't you?" To which Suzaku just smirks.
* MoralityPet: Murugu, though she's as gleefully sadistic as he is, she's still the only thing he's shown to care for.
* MusicalAssassin: uses the flute to control insects, but never uses it in combat for [[DoppelgangerAttack obvious]] [[ShockAndAwe reasons]].
* NightOfTheLivingMooks: His cultivated humans.
* {{Sadist}}
* ShockAndAwe: Uses it as arrows or [[ColdBloodedTorture shocking his enemies to death]].

[[folder:'''Team Toguro''']]
!!''Team Toguro''

The Demon Tournament team owned by the ludicrously wealthy Sakyo N., and led by the Toguro Brothers. They each have their own reasons for joining the team and fighting, but they also unanimously want to aid Sakyo in helping him construct an even bigger portal to the Underworld. Because, apparently, [[ForTheEvulz life would be more interesting that way]].
* '''[[{{Badass}} BADASS]]''': So much that their boss and his second in command can take multiple participants at the Dark Tournament at once, also their direct inferiors can defeat their enemies in a blink in an eye.
** BadassCrew: With the exception of [[NonActionGuy Sakyo]] and [[TheDarkChick Elder Toguro]], each is a major PersonOfMassDestruction in their own right
* LovecraftianSuperPower: Each one, with the exception of Bui and Sakyo, manifest their powers in a disturbing and CreepyAwesome kind of way.

Founder and Leader of the Apparition Gang and the captain and star fighter of Team Toguro, Younger Toguro is a former human turned demon and one of the main antagonists of the Rescue Yukina and Dark Tournament arcs. It's been fifty years since he last participated in the tournament, and it appears Yusuke has intrigued him enough to hope he has finally found a fighter worthy of his full 100% power. He has something of an ''interesting'' relationship with Genkai, to say the least.
* [[EightiesHair 80s Hair]]: A ''flat-top'' no less!
* AffablyEvil: A [[NobleDemon honorable fighter]] and [[PunchClockVillain only kills when required to]], unless [[BloodKnight you prove to be a worthy opponent]]
* AntiVillain - [[SlidingScaleOfAntiVillains Type I]]. Once he's defeated we find out his true motivations, [[spoiler: he lost all of his pupils and sought strength to exact revenge. Once he succeeded, he continued to punish himself by becoming a demon because he felt he could never suffer enough for his failure. And then he attempts to punish himself for his punishment during the main series]]. Even before that, he was a guy you couldn't help but admire.
* [[spoiler: TheAtoner]]
* BadAss: Oh yes.
* BloodKnight: Dislikes fighting weak opponents, but fights them anyway because it's a fight after all. [[spoiler: When Yusuke [[RoaringRampageOfRevenge attempts to beat the crap of Toguro for killing his one decent teacher]] only to lose instantly, Toguro [[NightmareFace is a little too happy that he is able to break his hand]].]]
** Once Yusuke doesn't give him a challenge, [[spoiler:he goes to kill one of his friends to get him to be more serious.]]
* CoolShades: Almost ''never'' seen without them. It's only at the very end of the Dark Tournament do we see his eyes.
* CurbStompBattle: Dishes them with each percentage necessary to defeat the enemy at hand.
* DeadpanSnarker: And not exactly subtle about it, either.
* DealWithTheDevil: Combined with HeWhoFightsMonsters when [[spoiler: he defeats Kairen (a demon who had much the same abilities as the Toguro Brothers) at the Dark Tournament 50 years ago, and, by winning, asks the Tournament Commitee to turn him and his brother into demons.]]
* [[spoiler: DeathSeeker: He wants to die at the hands of a stronger fighter...]]
** [[spoiler: HellSeeker: So he can go to the deepest pit of hell so he eternally be punished for not having the strength to protect his disciples.]]
* TheDragon: To Sakyo.
** DragonInChief: But he is '''much''' more dangerous than his boss.
*** DragonWithAnAgenda: [[spoiler: He's a DeathSeeker and thus hopes ''not'' to win the Dark Tournament. That doesn't go well with Sakyo's plan.]]
* EvenEvilHasStandards: Still finds some actions completely distasteful, especially those of his own brother.
* EvilCounterpart: To Yusuke, while Sensui is Yusuke's exact opposite; Toguro is more of if Yusuke decided to abandon his good tendencies and love for his TrueCompanions and gave in to his inner BloodKnight. Even his coat is olive green, a darker shade to Yusuke's usual outfit, Not to mention, they also share a DeadpanSnarker trait.
* [[spoiler: FallenHero: He fought evil demons and taught disciples to fight evil...then Kairen showed up and his beliefs were shattered.]]
* FingerPokeOfDoom: He can make peoples [[YourHeadAsplode heads explode]] by simply ''tapping on them'', which sounds [[HokutoNoKen suspiciously familiar]].
* GeniusBruiser: Despite being muscular, he is a WarriorPoet and a DeadpanSnarker, it's just that it's only limited to fighting.
* HealingFactor: Not to the same extent as his brother, but can regenerate a gaping hole in his body in seconds.
* [[spoiler: HeWhoFightsMonsters: Started off a martial artist fighting demons, but ultimately became one.]]
* HugeGuyTinyGirl [[spoiler: With his old teammate and friend Genkai.]]
* HumanoidAbomination: Especially at 100%
* TheJuggernaut: Spends the majority of his screentime being utterly implacable by even the strongest of fighters. Even Yusuke during the final round of the tournament is thoroughly outclassed during most of the fight, despite two power-ups though the third finally pushes him to Toguro's level.
* KickTheSonOfABitch: Literatelly kicks his older brother, then punches him into yet another temporary death. Ironically, in the dub, "son of a bitch" is what said brother calls Toguro when he does this.
** He also kills Gonzo Tarukane by literally kicking him in the back of the head, decapitating him in the process.
* LightningBruiser: Unlike most beings of his stature, Toguro is every bit as fast as he is strong and muscular, even at his maximum.
* MusclesAreMeaningless: A complete subversion. As he powers up, he becomes incredibly muscular in the process.
* [[spoiler: MyGreatestFailure: Not protecting his students from Kairen, a powerful demon, and even after defeating him in the previous Dark Tournament, he never let it go, turning himself into a demon and later going to the deepest circle of Hell in order to punish himself for this.]]
* NobleDemon: He's only in it for business and will only be brutal when it's necessary, compared to his sadistic brother
* NoHoldsBarredBeatdown: Most of his fights are [[CurbStompBattle Curb Stomp Battles]], but [[spoiler: his fight that he kills Genkai was nothing, but vicious as he [[ColdBloodedTorture slowly takes her apart, a piece of flesh to killing her by breaking her spine with his fist at 80%]]. It gets worse when Toguro goes [[OneWingedAngel 100%]], his fight with Yusuke becomes so one-sided, that it takes [[HeroicSacrifice Kuwabara's "death"]] to make Yusuke fight on truly equal terms. In fact it was so brutal that Yusuke in the middle of the fight passes out and dreams of the moment that he first meets Keiko... only for Toguro himself to appear in the dream as a huge monster that squeezes Keiko possibly to death. [[DespairEventHorizon it's so bad that the REAL Keiko snaps and loses consciousness]].]]
* OneWingedAngel: While does get more and more muscular, with 100%, he becomes a gray skinned monstrosity
* SinisterShades: Throughout most of his appearances.
* SympathyForTheDevil: His FreudianExcuse definitely earns this.
* SpiritedCompetitor: Does not like fighting weaklings at all, [[spoiler: [[BloodKnight but is very excited when Yusuke can provide a challenge to him]].]]
* StartOfDarkness: [[spoiler: goes insane after a demon kills his students, and even after killing him, he felt that he needed to be punished for it for all time.]]
* StealthMentor: [[spoiler: towards Yusuke, he pushes Yusuke to be stronger and his words during his fight with Yusuke seem to a SecretTestOfCharacter in hindsight, so he won't be completely consumed by battle.]]
* TheStoic: One of his most notable attributes is his constant poker face.
** NotSoStoic: [[spoiler: when he goes 100%]]
* UnskilledButStrong: He's a very skilled martial artist--he just prefers relying on absolute strength.
-->''"The strength to make all tactics useless. '''That''' is strength absolute."''
* UpToEleven: [[spoiler: 100% of 100%.]]
* WalkingShirtlessScene: The guy ''loves'' to take off his coat. Justified in that his main power is expanding his muscles, so it would be a shame to damage [[BadassLongCoat his nice coat.]]
* WhenAllYouHaveIsAHammer: Notes that brute strength is the only thing he's really good at, but manages to get by with that, [[CurbStompBattle beating everyone that got his way.]]
* WithGreatPowerComesGreatInsanity: The more he uses his power, the more his bloodthirsty urges seep out.
* WorthyOpponent: Views Yusuke as one [[spoiler: as well as [[DeathSeeker the one to end his miserable existence]].]]

Co-Leader of the Apparition Gang, and vice-captain of Team Toguro. Elder Toguro is a human turned demon shapeshifter who usually rides on his brother's shoulder, and often fights alongside him. He can alter the shape of his body to form weapons or to move his organs to escape harm, and also has powerful regenerative abilities, almost to the point of immortality. Infamous due to his cruelty and sadism, even for [[TheSociopath Sakyo's standards]].
* [[spoiler:AndIMustScream: How he's finally taken care of, considering that he simply ''can't'' die.]]
* [[spoiler: AssimilationBackfire: When Sensui Seven member Gourmet eats Elder Toguro to get his powers, Elder Toguro ends up taking over his body later.]]
* AxCrazy: Gets more and more insane throughout the series until he's completely lost it.
* [[spoiler: BeCarefulWhatYouWishFor: He finally gets a body that can never die, but soon regrets as he's trapped in a LotusEaterMachine for all eternity]]
* BodyHorror: His power involves manipulating his body into anything, and shifting his vital organs around. [[spoiler: it gets worse when he becomes a parasite after taking over Gourmet's body.]]
* CardCarryingVillain: Fully aware of the fact that he's depraved, honorless scum and enjoys every second of it.
* [[spoiler: CompleteImmortality: Gains this after getting HealingFactor boost after being hit by his brother, [[BeCarefulWhatYouWishFor but is soon sealed away in a plant for all eternity]]]].
* TheDarkChick: Unlike his [[PersonOfMassDestruction teammates]] excluding Sakyo, his acts do not ultimately do much damage outside the ring.
* DirtyOldMan: Being in his 80s, he's obvious the elder sibling, he also admitted [[RapeIsASpecialKindOfEvil he admitted he wanted to take advantage of Genkai when he was human]], [[KickTheDog then insults her age in a more disrespectful manner than his brother]]. [[MegatonPunch Younger was not amused]].
* DubText[=/=] FoeYay: Complains that Kurama's not as pretty in his human form, but only in the English version.
* [[spoiler: EatenAlive: Played straight then darkly inverted, he is eaten by Gourmet, but takes over his body from the inside out, causing the latter to commit suicide in order not to be EatenAlive himself]]
* EeriePaleSkinnedBrunette: White skinned, which begs the question on how he and his younger brother are related.
* EmbarrassingNickname: Is often called "Toguro's shoulder monkey", in-universe included.
* EvilFeelsGood: [[spoiler: Especially in Gourmet's death, which he notes to be like being on ecstasy]]
* EvilGloating: Very guilty of this, it led to his defeat [[spoiler: and prompt FateWorseThanDeath for all eternity]] on two separate occasions
* [[spoiler: FateWorseThanDeath: He is trapped in a hallucinogenic plant that feeds on his life force indefinitely.]]
* FauxAffablyEvil: Sure he seemingly presents quite a polite and gentlemen-like demeanor toward his victims, but that's only because he's ravishing in his sadistic nature by torturing them ''physically'' and ''emotionally''.

!!''Sakyo N.''
'''Species:''' Human\\
'''Main Power:''' None]

-->''My brothers all took honest, white-collar jobs, with wives and kids. If I had their lives, I'd kill myself. Luckily, their fate was not meant for me. I was too smart.''

->Voiced by: Nobuyuki Furuta (JP), Creator/EricVale (EN)

Sakyo is the wealthy owner of Team Toguro and a member of the underground Black-Black Club. While he appears to be calm and charismatic, 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. He accumulates a vast fortune which he plans to use to create a hole to the demon world, [[ForTheEvulz for no other reason than to just see what happens]]. For a short while, he was Shizuru's romantic interest.
* AffablyEvil: He's very polite and gentlemanly for a villain, especially towards Shizuru.
* AxCrazy: In his younger days, he enjoyed dissecting animals, and eventually humans. Present-time, however, he seems to have [[BoredWithInsanity moved on from that particular sin.]]
* BigBad: Of the Dark Tournament saga.
** BiggerBad: Eventually becomes this [[spoiler: after his self-inflicted demise]], since his past actions have deep repercussions during Chapter Black, [[spoiler:since Itsuki more or less picked up on digging through the tunnel where he left off. Even worse, Sensui had his mental breakdown in one of ''his mansions'', where they were torturing demons and bathing in their blood]].
** NonActionBigBad: He serves as the fifth member of Team Toguro, but acknowledges that he can't fight. [[spoiler:His "match" with Koenma ends up being tied to the outcome of Yusuke's match with Toguro, essentially meaning that with Yusuke's team having lost one match and won two, the team who won in that case won the round and the tournament]].
* {{Bishonen}}: Reasonably attractive, even with the scar on his right eye.
* BoredWithInsanity: Sort of--he eventually became bored with personal killing and torturing, and [[TheGamblingAddict found gambling to be his truest pleasure.]]
* CardCarryingVillain: Freely admits that he doesn't have a FreudianExcuse and is just rotten to the core for no reason.
* TheChessmaster
* CorruptCorporateExecutive: Gambling on the torture and destruction of demons, and organizing a tournament for this reason, just to earn more money...
* DeadpanSnarker: A villainous example.
* DubText: Even though the original Japanese Sakyo was ''still'' a sociopath, he remembered his happy childhood with a warm fondness, genuinely loved his family (''"My parent were decent and kind people; it was what you could call an ideal family"'') and blamed nobody but himself for how he turned out, the English dub added a ''lot'' of changes to his narration, making him '''hate''' his parents and swearing he would kill himself if he became a white-collar worker.
* EvenEvilHasStandards: It is poor taste for a gambler to cheat, and Sakyo [[TranquilFury does NOT tolerate poor taste]] gracefully.
* [[spoiler: FaceDeathWithDignity]]
* FictionFiveHundred: He is able to stake the equivalent of ''Japan's entire national budget'' like it was ''pocket change'' when betting on the victory of Yusuke and Kuwabara over the Toguro brothers with Torukane Gonzo... [[spoiler: but then again, he KNEW Toguro would throw the fight for him and more importantly LIVE to report it.]]
** The dub ups the ante by keeping the figure 66 trillion+, but implying that it's US dollars, as opposed to Japanese Yen, which increased the figure by two orders of magnitude to more than the annual economic output of the entire planet (noted by two members of the Black Black group: one says, "That's more than Japan's Gross National Product," and another adds, "It's more than any nation's product").
* ForTheEvulz: Wants a portal to the Makai to be opened...just so life will be more interesting as the world goes to hell. [[spoiler: he gets his wish in the end, but it's not the way he wanted to]].
* TheGamblingAddict
* GoodScarsEvilScars
* [[spoiler:GoOutWithASmile]]
* IGaveMyWord: For all his flaws, Sakyo is a deeply honorable man whose word is his ''absolute'' bond; if he promises you that he'll kill himself for losing a bet, he '''means''' it.
* KickTheSonOfABitch: While he does have some [[KickTheDog genuinely evil moments]], at least two of them has him offing some ''very'' {{Corrupt Corporate Executive}}s... to further his own ends, of course.
* LongHairedPrettyBoy: Has more of a mullet, leads to the same FaceOfAnAngelMindOfADemon effect as Karasu
* ManOfWealthAndTaste
* TheManBehindTheMan: He's in charge of Team Toguro, and is thus the true villain of the Dark Tournament saga.
* NightmareFetishist: He claims to have been fascinated by death and suffering since childhood.
* NonActionGuy: In a DoubleSubversion, he reveals himself as the fifth member of Team Toguro... before wagering his life on Toguro so he doesn't have to fight.
* PetTheDog: His interactions with Shizuru (Anime only).
* [[spoiler: PosthumousCharacter: Even after his death, he still has an influence on the Chapter Black saga via Sensui's backstory. [[ChekhovsGun His plans are ultimately fulfilled by a man not only stronger then his top fighter, but is much smarter than him]] and ironically by one of his original enemies: Former Spirit Detective Shinbou Sensui.]]
* SharpDressedMan
* SmokingIsCool
* TheSociopath: His backstory tells us how he would torture animals when he ran a pet shop, and only entering the dark underground because he could gamble lives including his own.
* [[spoiler: TakingYouWithMe]]: [[spoiler: Sort of a half-hearted, unintentional example. After Team Toguro's defeat, he graciously accepts defeat and sets the stadium to self-destruct with himself inside it...without waiting for anyone to actually get out first.]]

'''Species:''' Demon\\
'''Main Power:''' Explosive Touch]

-->''Your red hair is perfect for that fiery spirit that I admire. You know that's why I've decided to leave your beautiful face unharmed. I may not be able to keep you, but I'll always have the memory of your face to give comfort.''

->Voiced by: Creator/RyoHorikawa (JP), Creator/KyleHebert (EN)

Karasu is a Quest class demon. He is able to use his aura to create bombs undetectable by lower level demons, as well as create bombs within his victims. He wears a mask over his mouth which restricts his unstable powers. He is also able to use his entire body as an explosive. [[DepravedHomosexual He takes quite a liking to Kurama.]]
* AxCrazy: Not as much as Elder Toguro, but he is [[{{Yandere}} dangerously obsessed]] with killing Kurama.
** [[DissonantSerenity He's far more dissonant about his insanity]] than Elder Toguro's blatant madness.
* BadAss: Even if he is [[AxCrazy nuts]], the guy is ''just plain awesome'' as far as his powers are concerned.
** BadassLongcoat: Rocks the trench coat and CoolMask look.
* {{Bishonen}}: A definite one for the villains's side.
* CoolMask: A gray one with tiny spectacles [[spoiler: it acts as a restraint for his powers.]]
* DepravedHomosexual: In love with Kurama and shows this with his desire to ''kill him''.
* DissonantSerenity: What makes him so dangerous other than his powers is that he is so calm and nonchalant than you wouldn't know he was crazy at first sight.
* EvilGenius: Take a good look, ladies and gentlemen; this is one of the few men who can outsmart Kurama.
* MadBomber: His fighting style, utilized by conjuring hand-grenades, dynamite and mines.
* LightningBruiser: Is ''extremely'' fast and swift. He can plant sticks of dynamite on you before you even notice he's moved.
* PowerLimiter: [[spoiler: He becomes much more powerful (and psychotic) once his mask comes off.]]
** [[spoiler: Also, [[PowerDyesYourHair his hair turns blond when said limiter comes off.]]]]
* PsychoForHire: Is one like Elder Toguro, but has DissonantSerenity to back it up
* PyrrhicVictory [[spoiler: Despite being killed, he wins his match via a technicality.]]
* {{Sadist}}: He does like seeing his prey in agony
* StalkerWithACrush: To Kurama.
* TheStoic: Normally this, even in his {{Yandere}} moments [[spoiler: when his mask is on.]]
** NotSoStoic: [[spoiler: When his mask comes off.]]
* ShoutOut: [[spoiler: Once he enters his SuperMode, Koto makes one to ''DragonBallZ''. Seeing how his voice actors are Teen Gohan in the U.S. and Vegeta in Japan, the directors were in on the joke...]]
* {{Tengu}}: His name means "Crow" and his mask and design is similar to that of anthropomorphic japanese crows. When flowing, his longcoat also resembles crow wings.
* {{Yandere}}: A male version, for Kurama.

'''Species:''' Demon\\
'''Main Power:''' Battle Aura]

-->''I only put enough energy into my attacks as is necessary to defeat my opponents. That wasn't even enough to scratch me. Take that any way you want.''

->Voiced by: Tetsuo Kaneo (JP), VicMignogna (EN)

Bui is a demon warrior who possesses an immense battle aura. When he was younger Bui fought Younger Toguro and lost. He swore he would train and one day defeat him so Toguro invites Bui to join his team as he trains, but Bui is unable to surpass him. He wears heavy armor to suppress his aura and wields an axe larger than his own body.
* AntiVillain: Even more so then Younger Toguro since we never see him commit any despicable acts like his four teammates and prefers to give his opponents in battle a quick death.
* AnAxeToGrind: His main weapon, until he uses his battle aura.
* ArousedByTheirVoice: [[LampshadeHanging Lampshaded]] in-story.
* BadAss: The second-strongest member of Team Toguro, and a master of energy manipulation. His aura is so strong that it literally lifts him off the ground just by releasing it.
* BattleAura: When he removes his armor.
* TheBrute: He's so freakishly strong that he's able to deflect and toss Hiei's darkness dragon up in the sky.
* [[spoiler: DeathSeeker: Wants to die after Hiei defeats him, believing he cannot get any stronger. Not that Hiei obliges to do so.]]
* EvilSoundsDeep: He's not ''evil'' per say, but he does have a deep, sexy voice - lampshaded in-story.
* GeniusBruiser: ''Much'' more intelligent than he appears.
* HiddenDepths: He looks like a silent brute who wears bulky armour and carries a heavy axe... before losing the axe, taking his armour off, and using his Spirit Energy to fight whilst eloquently chatting with Hiei.
* LightningBruiser: Significantly faster than his opponent in the semifinals expected.
* [[spoiler: PowerLimiter: His armor acts a power restraint that keeps his battle aura under control.]]
* TheQuietOne: Never speaks until his fight with Hiei.
* ShedArmorGainSpeed: Not surprising since his armor is a PowerLimiter. Even with it on he's faster than he seems, but once he removes it he's capable of flight and even faster.
* VillainByDefault: Only really consider a bad guy because he's on Toguro's team.
* WhatHappenedToTheMouse: Never seen again after Hiei spares him. The last time we see him in the manga, he's watching Yusuke's fight with Toguro.
* YouGottaHaveBlueHair

[[folder:'''The Sensui Seven''']]

!!''The Sensui Seven''

A collective of complete psychos who plan to finish Sakyo's work in opening the portal to the Underworld. They however aren't in it for the amusement, but because they personify the whole HumansAreBastards philosophy, and want ''absolutely everyone dead.'' They are lead by former Spirit Detective Shinobu Sensui, a tour de force of sheer crazy. In contrast to Team Urameshi's previous enemies, the Sensui Seven are comprised entirely of humans (save for Gatekeeper), and ironically enough (or ''because'' of that) are also their greatest enemies.
* AxCrazy: Varies from very obvious to subtle DissonantSerenity.
* BadassCrew: Their mental games and nasty moral dilemmas easily make them Team Urameshi's toughest opponents.
* CodeName: They all operate using code designations instead of their real names. (Black Angel, Gatekeeper, Sniper, Seaman, Gamemaster, Gourmet and Doctor). [[spoiler:Save for Elder Toguro.]]
* DrivenToSuicide: Don't seem to mind that their plan might mean that they'll be killed by demons as well; though [[LockedOutOfTheLoop Gamemaster seems to not realize this]]
* SevenDeadlySins: Each represents a Sin respectively, Seaman (Envy), Sniper (Pride), Gamemaster (Sloth), Doctor (Wrath), [[CaptainObvious Gourmet]] (Gluttony), Sniper (Pride), Gatekeeper (Lust) and [[spoiler: Elder Toguro]] (Greed); with Black Angel being without sin [[spoiler: unless you count the flawed six other personalities he has]]
* YouHaveOutLivedYourUsefulness: They generally have this attitude towards one another when they're cornered.

!!''Black Angel - Shinobu Sensui''
'''Species:''' Human\\
'''Main Power:''' Resshūken / Sacred Energy]

-->''Never satisfied, never full, they eat and destroy with grubby hands till nothing is left but piss, but now the judgement of all humans has begun.''

->Voiced by: RokuroNaya (JP, adult), AkiraIshida (JP, younger) RobertMcCollum (EN)

Shinobu Sensui - codename ''Black Angel'' - is the previous Sprit World Detective and the main antagonist of the Chapter Black arc. During a routine case Sensui came upon one of Sakyo's hideouts for the then-early Black-Black Club, a mansion where humans were torturing demons, [[BloodBath bathing in their blood]], and committing other acts of unspeakable evil. Seeing the cruelty of those he was sworn to protect Sensui went mad and slaughtered everyone and everything there. He soon disappeared, taking with him a video known only as Chapter Black, a video tape kept in the vaults of the underworld containing footage of the most evil deeds of humanity. Sensui then waited until Koenma appointed a new Spirit Detective before coming out of hiding, springing his plan to judge the human race.
* AffablyEvil: [[spoiler: His real personality is this. Shinobu is shown to have a kind and polite personality, even wanting to shake Yusuke's hand when they first meet. He even shows genuine remorse after he kills Yusuke, and he is very understanding of Yusuke's friends wanting to seek vengeance. Despite all of this, that does not stop him from wanting to kill all humans.]]
* AlliterativeName
* ASinisterClue Yep, he's left-handed.
* AxCrazy: [[spoiler: His "Kazuya" personality]], with a heaping side of {{Gorn}} and CombatSadomasochist!!!
** Though he is still insane for having [[spoiler: seven personalities including a psychotic killer and a girl. It's just that Kazuya is the most ''blatantly'' insane.]]
* {{Badass}}: The strongest full-blooded human in the series [[spoiler: till he dies, and passes that title to Kuwabara]]
* BadBoss
* EvilPlan: Open a portal to Demon World and flood the Earth with demons because he hates humans. [[spoiler: His true goal was simply to reach demon world and be killed by a demon because of his guilt at killing them for so long to protect humans that were just as bad if not worse.]]
* BigBad: Of the Chapter Black saga.
* BlackAndWhiteInsanity: What broke him.
* BloodBathVillainOrigin: To be fair, the Black Black Club deserved it.
* [[BlueOniRedOni Blue Oni to Yusuke's Red Oni]]
* BoomerangBigot: A human leading a crusade of genocide on the entire human race.
* [[spoiler: CoveredWithScars]]: [[spoiler: They're self inflicted]].
* TheChessmaster: Yusuke and his friends have become so adept combating evil as warriors that Sensui's cerebral, calculating and ruthlessly ''intelligent'' evil renders them ''completely'' helpless.
* CurbStompBattle: Most fights with him are this, especially the three on one. When fighting seriously he is among the most powerful villain in the series, which is saying something since the rest of them are demons. It takes [[spoiler:Raizen, who has been stated to unequivocally the most powerful character in the entire series according to the author,]] to intervene to finally beat the guy. The real irony? [[spoiler:The guy was already dying to begin with]].
* CryForTheDevil: [[spoiler: His death speaks go this]]
* DangerouslyGenreSavvy: More than just his prior Detective experience, Sensui has a fond love of movies and video games - a love his has absolutely no qualms about using to his advantage - from tricking Gamemaster into challenging Yusuke's crew to ''Goblin City'', to ''perfectly timing'' the runtime of a Vietnam war flick to his fight with Yusuke....so that [[spoiler:Yusuke's death]] would be ''immaculately on-sync'' with the end-credit song. ''It works, too.''
** Also when Gourmet/[[spoiler: Elder Toguro]] proved to be useless as he needed Kuwabara's power to activate with the latter being unable to use it, he goes for RoaringRampageOfRevenge, knowing that he'd do anything to avenge his friend and even cut open Hell itself to do it.
* DarkMessiah - Interesting in that he was one FaceHeelTurn away from being an actual Messiah.
* [[spoiler: DeathEqualsRedemption: Sort of, in the anime. He does regret the path he and his other personalities took as he dies and says that Yusuke found balance between demonkind and humanity in a better way than he could have. In the manga, he's unrepentant to the end, and simply dies wishing he'll be reborn as a demon.]]
* [[spoiler: DeathSeeker Combined with SuicideByCop.]]
* DeathOfAThousandCuts: What the Splinter Roushuyuken does
* DepravedHomosexual Subverted/played around with/deconstructed/possibly inverted.
* DoesThisRemindYouOfAnything: [[spoiler: The speech he gives before he dies about having to fight demons from a very early age and having to come to terms with it sounds an awful lot like him recalling his ComingOutStory. Especially in the dub.]]
* DrivenToVillainy: Thanks to that [[HumansAreTheRealMonsters damn Black Black Club]]... though it's also kind of his own fault as well. Sensui's [[BlackAndWhiteInsanity inability to see any issue other than in black and white terms]] is what made him unstable; if his ideas hadn't been coiled so tightly in his head to begin with, he wouldn't have snapped like he did in the first place.
* EvilGenius: A rare DarkerAndEdgier version that's also the BigBad in the series.
* EvilCounterpart: To Yusuke.
* ExtremityExtremist / EnergyBall
* FaceHeelTurn: After going nuts.
* FacialMarkings: His bindi.
* FallenHero: Used to Spirit World's finest till everything went to hell.
* FauxAffablyEvil: [[spoiler: As Minoru,]] Sensui is polite, refined, and utterly twisted.
* GeniusBruiser: Up there with Kurama, Karasu, Kaito, and Yomi as one of the most intelligent characters in the series, as well as the series' most skilled martial artist and first [[spoiler:S-Class]] shown.
* GoldenSuperMode [[spoiler: The main Shinobu personality's Sei-Kou-Ki/Holy Energy.]]
* GoMadFromTheRevelation: He '''definitely''' saw some things he shouldn't have, [[SplitPersonality that broke his brain...]] However, the madness was aided and abetted by the [[BrownNote Chapter]] [[PostHistoricalTrauma Black]] [[SnuffFilm tape]].
* GoodHairEvilHair: It's slicked back when he appears as a BigBad, but in flashbacks, when he's a Spirit Detective, it's more of a bowl cut.
* HeWhoFightsMonsters: He believed in this so strongly that it ultimately broke him when he found out the possibility [[HumansAreFlawed that humans are not the saints that they're made out to be.]]
* HumansAreTheRealMonsters: His pet hangup.
* KillAllHumans: His stated goal and mission [[spoiler:though it turns out to be a secondary aim to his ''true'' goal of being a DeathSeeker.]]
* KnightOfCerebus: If Toguro brought the series to a darker, more serious tone, then Sensui basically brings forth hell, brimming with the worst of humanity and Armaggedon.
* KnightTemplar: Despite being the most "morally pure" of his personas , his original and strongest personality, ''Shinobu'', fits this trope given that he strictly adheres to a [[BlackAndWhiteInsanity highly inflexible black-and-white belief system]] regardless of the costs of doing so.
* LightEmUp ([[spoiler: his main personality's Sei-kou-ki/Holy Energy. Also an example of LightIsNotGood.]])
* MachoMasochism: Double-subverted. When he takes off his shirt after [[ItMakesSenseInContext falling into the lake]], the first thing the heroes notice about him are his [[GoodScarsEvilScars scars that criss-cross his whole body]]. They assume at first that it was from all of the demons he had to fight when he was younger; however, it's revealed that he got all those scars ''training himself''. Yusuke lampshades it in the dub:
--->'''Yusuke:''' Awww, jeez, a masochist!
* ManipulativeBastard: His [[spoiler: split personality, Minoru]] persona.
* PersonOfMassDestruction: While nothing is totally concrete, Sensui as well as Koenma have implied that S class level fighters can wreck entire planets. Very likely the reason why no S classes ever fought on Earth. And guess what, Sensui was [[UptoEleven the weakest one]].
* PsychopathicManchild: Type B and C. While he does act like an intelligent and sophisticated adult, he still has the immature mindset of child who can't accept the complexities of life.
* PureIsNotGood: If Sensui wasn't so pure as a good guy, he couldn't have become so tainted as a villain. [[spoiler: His main 'Shinobu' personality is still pure and innocent after all these years. [[AmbiguousInnocence Sort of]].]]
* PurpleIsPowerful / SupernaturalIsPurple: His bindi and {{Ki Attack}}s.
* SevenDeadlySins: [[spoiler:While Kamiya (Wrath), Makihara (Gluttony), Hagiri (Pride), Mitarai (Envy), Amanuma (Sloth), Itsuki (Lust) and Elder Toguro (Greed) represent the seven deadly sins of the Bible, the true Sensui (excluding Kazuya - Wrath), the unnamed female personality (Lust) and Minoru (Pride), is devoid of any true sin, like a fallen angel who still upholds his duties even if they are warped from his original goals. Hence, his Black Angel title. ]]
* ScrewTheRulesIHaveSupernaturalPowers: Part of his attitude/egotism after becoming a villain, in addition to hating humans.
* SerialEscalation: He can manipulate an energy ball that he uses to various, deadly ways, [[spoiler: has seven personalities, each with a deadlier power]], which is good for a ClimaxBoss, but reaches ridiculous levels of power with Sacred Energy which can level the planet with its mere presence and shape itself to various kinds of armor.
* SignificantBirthDate: June 6th. Add in his year of birth (1967, given that the Sensui Arc takes place in 1993), write it numerically (6/6/67), and you get the NumberOfTheBeast with a [[{{Foreshadowing}} seven]] left over.
* [[spoiler: SplitPersonality]][[spoiler:Seven including the original, in total after losing it.]]
* [[spoiler:SoapOperaDisease: He was suffering from terminal cancer, and had only a few months to live. One of the reasons why he's ''far'' more ruthless and efficient with his plan than any other villain - he had only a short time to execute it.]]
* StartingANewLife [[spoiler: After the events of YuYuHakusho, Minoru Kamiya changed his face and name to evade law enforcement agencies due to his involvement with the Sensui Seven. He founds a clinic to help heal others, which was a result of realizing that the group lost their fight against Yusuke and his comrades, which contributed somewhat to his HeelRealization.]]
* StartOfDarkness: Exposure to the depravity of humanity and then the Black Chapter tape
* StraightGay: By WordOfGod.
** BadassGay: Yeah, he's a villain, and he has a lot of issues, but he's also a [[YoungConqueror martial-arts prodigy born with a very strong spiritual sense]] and the WorldsStrongestMan [[spoiler: until his death]].
* SympathyForTheDevil: His world view was shattered and he spent his whole life trying to understand the creatures he hunted [[spoiler: and the resulting guilt of those actions led him to SuicideByCop]]
* TheReasonYouSuckSpeech: Given to Yusuke by Minoru
* TheUnfettered: Even when he is was a good guy, he used the absolute extremes to deal with demons.
* TVGenius: Sensui is ''extremely'' smart, but he seems to have no clue how to relate to people beyond using and/or killing them. NotGoodWithPeople is, in his case, an ''understatement''.
* [[spoiler: VictoriousLoser / DoomedMoralVictor: Sensui, in dying, achieved what he wanted, and in the manga, his ideology colors the rest of the series as we find out more about the diversity of demons. This is lampshaded by Yusuke after his death.]]
* WellIntentionedExtremist: At least his true personality, ''Shinobu'' is.
* YaoiGuys / OfficialCouple / MindGameShip / BirdsOfAFeather / UnholyMatrimony: Him and Itsuki.
* YoungConqueror: Was born with very high spiritual awareness as well as being a martial-arts prodigy, in contrast to Yusuke's IdiotHero.

!!''Gatekeeper - Itsuki''
'''Species:''' Demon\\

-->''Four times zero power is still zero power.''

->Voiced by: KoujiTsujitani (JP), Jerome 57 (EN)

Itsuki - codename ''Gatekeeper'' - is a demon who can traverse dimensions and Sensui's left-hand man. He is an immensely powerful psychic capable of tearing open entire holes between dimensions through pure meditation, and as such he's the ''other'' necessary key to bring forth Sensui's judgment. Having been with Sensui the longest he has grown very fond of him, stating that he wishes for Sensui to be his lover. Itsuki controls a being known as the Reverse Man, a shadow living between dimensions.
* AxCrazy: A DissonantSerenity type who is much worse in the manga when he compares Sensui's downfall to watching a sweet little girl becoming a whore and being intoxicated with this fact.
* {{Bishonen}} / LongHairedPrettyBoy
* CorruptTheCutie: In the manga, his motive for why he started to hang around Sensui. It's still there in the anime (especially the dub), but ''nowhere near'' as noticeable or blatant. One of the main reasons why Sensui/Itsuki is a MindGameShip.
* DissonantSerenity: Itsuki seems to be a very mellow, quiet guy on the surface - but he ''will'' unexpectedly snap, especially when Sensui is about to do something violent (which he agrees with only because of MadLove). Also, his Ura-otoko is full of dead bodies, airplane wreckage, etc.
* TheDragon: Sensui's left hand.
* EvilGenius: And here's the ''other'' man who can outsmart Kurama. Might be played with because it's not clear of he outsmarted Kurama or just ''out-crazied'' him.
* EyesDoNotBelongThere [[spoiler: His shadow hands are ''covered'' in unblinking PurpleEyes]].
* FauxlosophicNarration: About half of his speaking lines are this.
* HappinessInSlavery: To Sensui.
* [[spoiler: KarmaHoudini]]
* MadLove: To Sensui
* ManipulativeBastard: Of the passive-aggressive variety.
* MoralMyopia: His last speech is filled with this. He calls out Team Urameshi and Spirit World for their crimes in an attempt to justify his and Sensui's goals, despire what he and Sensui did.
* MultiArmedAndDangerous: His shadow hands.

** ActionSurvivor: He ''does'' have [[VillainTeleportation supernatural]] [[MultiArmedAndDangerous powers]], but [[NonActionGuy they're not very useful in battle]]. However, he gets by by being a ''ginormous'' ManipulativeBastard...
* ThePhilosopher: Somewhat of a subversion, as he's bloody crazy.
* PsychoSupporter: Itsuki from the anime ''loves'' [[BigBad Sensui]] because... Sensui is beautiful. In all kinds of senses, with a stress on the functional beauty of tremendous power.
** In the manga, where Itsuki is more twisted, it's because he's gotten the opportunity to see all that [[IncorruptiblePurePureness purity]] get twisted and warped and spit out a shattered genocidal maniac who's more powerful than ever and still charismatic and brilliant. He compares it to [[CorruptTheCutie "a little girl who believes babies come from storks growing up to star in pornos."]] He loves that kind of thing. He plays this ''so'' straight.

* SingleTargetSexuality: Taken to a very obsessive degree - he loves Sensui. A LOT.
* SingleSpecimenSpecies: The ''only'' yaminade left.

!!''Sniper - Kaname Hagiri''
'''Species:''' Human Psychic\\
'''Main Power:''' Marksmanship / Death Print Bull's Eye]

-->''I've got no quarrel with you, stranger.''

->Voiced by: Eiji Sekiguchi (JP), Aaron Hatch (EN)

Kaname Hagiri - codename ''Sniper'' - is a human psychic who acts as Sensui's right-hand man and top field operative, always by his side offering combat support. An extremely cold and efficient assassin and one of Team Urameshi's deadliest opponents, any object he throws within his territory will hit its mark with deadly speed and perfect accuracy.
* AlwaysAccurateAttack: His territory allows him to fire objects at incredible speeds and force, and will ''always'' home in on their marks, though anyone quick enough can stop them and once stopped they lose the ability to follow their target.
** ImprobableAimingSkills: When someone is in his territory, and he can mark them to allow objects to home in on them.
** Genkai was on-edge when she realized he shot Murota from 500 yards (five football fields) in the head with a ''pencil eraser'' ''- '''without''' killing him.''
* BadAss: Aside from [[spoiler:Younger Toguro and Sensui himself]], he comes closest to actually killing Yusuke. Genkai was promptly terrified when she realized how he shot Murota.
* BadassBiker
** [[BikerBabe Biker Bishie]]: He seems to fit this trope better than BadassBiker, especially knowing [[StraightGay his boss]]...
* ColdSniper: An interesting twist. Per say, he doesn't actually ''use'' a real sniper rifle (he ''does'' use a pistol), but he can flick objects (marbles, dice, ''[[UnusualAmmo a tank truck filled with fuel]]'') with ''insane'' force and accuracy. Moreover, his "territory" lets him imprint enemies with bulls-eyes that attract anything he throws with deathly speed. That said, personality-wise he fits the bill of the ColdSniper quite well - out of all the Sensui Seven, he's the least emotional and crazy, and fights purely methodically. (Though he can also be NotSoStoic, and after Itsuki he is the most unfalteringly loyal to their leader Sensui.)
* CombatPragmatist: He's not above toying with his victims, but he never lets it go on for too long either.
* CurbStompBattle: Yusuke's fight against him was absurdly one-sided. In all his experience, Yusuke was always used to fighting enemies head on, but never against somebody who methodically kept his distance and chipped away at him. If it wasn't for [[spoiler:Hiei's [[BigDamnHeroes big damn heroic moment]]]], Yusuke would've been dead a second time.
* TheDragon: Sensui's right hand.
* EeriePaleSkinnedBrunette
* EnigmaticMinion
* EvenEvilHasLovedOnes: About the only human he truly cares about is his sister - she even somewhat serves as his MoralityPet, not that it deters him from his goals.
* ForTheEvulz: Like Itsuki, Hagiri could care less about the Chapter Black and the evils of humanity. He is mainly motivated by a massive superiority complex: He finds most everyone around him too stupid and not worth the dirt they walk on, and thus they deserve to be replaced with Demons. He does however value his family.
* TheGunslinger: Always carries a pistol with him, [[CombatPragmatist just in case]].
* ImpaledWithExtremePrejudice: By Hiei, [[spoiler:non-fatally]].
* ImprobableWeaponUser: Let's see, he uses dice, marbles and shot a guy on the head bloodtastically with a pencil eraser.
* [[spoiler: KarmaHoudini]]
* NothingPersonal: Says this to Hiei right before he was about to shoot him.
* PsychoSupporter
* SevenDeadlySins: As one of the Sensui Seven, he represents {{Pride}}.
* ShoutOut: Honestly, who doesn't think he looks a bit like [[Manga/{{Akira}} Kaneda]]?
* SquishyWizard: Practically unstoppable at a distance. If that distance is closed however, the threat level plummets.
* ThereIsNoKillLikeOverkill: Lampshaded by both Yusuke and Kaname himself when he locks a ''fuel tanker'' onto Yusuke's bull's eyes.
* UndyingLoyalty: Is the most loyal to Sensui, after Itsuki.
* WeakButSkilled: There's a reason he's called ''[[MeaningfulName Sniper]]''. For how hax his powers are, he's a regular human, and would be knocked out by a direct him from any main character.
* WhyDontYouJustShootHim: After playing around with Yusuke as target practice, he finally opts to just gun him down with a pistol. [[spoiler: If [[BigDamnHeroes Hiei didn't arrive in the nick of time]], that definitely would've been the end of him]].

-->''You can't avoid it any longer. You have to kill me - cross the ultimate line that divides all men - but you've NEVER killed a human and, once you do that, you could never go back to the other side. It's like a narcotic. You have to keep on killing or else the guilt will overcome you. At least that's the case with me.''

->Voiced by: Taro Arakawa (JP), Creator/SonnyStrait (EN)

Minoru Kamiya - codename ''Doctor'' - is a human Psychic and one of the Sensui Seven. An extremely deranged and disturbed man, he is fully aware that the goal he strives for will result in his (and everyone else's) death - and he's perfectly fine with that, seeing humanity as a disease that needs to be eradicated. Within his territory he can create viruses, reattach limbs, alter his own body chemistry and wield a psychic scalpel which he uses with surgical accuracy.
* AxCrazy: He was going to kill every person in an entire hospital, paralyzed Kido, and slashed a woman's torso open. And he did it all with a smile.
* BadAss: The guy is freaking ''spry'' for a doctor! And while he's hardly the strongest opponent Team Urameshi has faced, the situation which he creates for them makes him one of their most dangerous.
* BrainwashedAndCrazy: One way of looking at his mad acts is that the horrible scenes of humanities' worst crimes on Chapter Black made him decide to have all humanity die
* DespairEventHorizon: What he saw on Chapter Black, made him nihilistic enough to wish for the death of all humanity
* [[spoiler: FacialHorror: Courtesy of Yana. He got better looking in the epilogue]]
* FourEyesZeroSoul: He was once of the most sadistic members of Team Sensui, at least before [[spoiler: he escapes from prison, changes his face, and founds a clinic to help others.]]
* GoodPowersBadPeople: Has HealingHands, but uses them to kill others
* HealingFactor: He can numb the pain receptors and use his ability to reattach his limbs
* HealingHands: He can reattach limbs with his powers, making him very hard to put down [[spoiler: however, he decides to use those powers for others later one]]
* [[spoiler: HeelRealization: After a short while after the Sensui incident, he realizes that he was very wrong and decides to help others]]
* [[spoiler: KarmaHoudini: Despite almost killing an entire hospital and giving an innocent nurse a three-foot-long scar, in the epilogue, he gets to use his skills to become a doctor for the weak and change his face to boot, and this is after admitting to still wanting to complete their goal of creating hell on earth after a well deserved NoHoldsBarredBeatdown from Yusuke]]
* MadDoctor: This guy is freaking crazy [[spoiler: [[HeelRealization he realizes that he needs to make amends for his actions]]]]
* MorallyAmbiguousDoctorate / DeadlyDoctor: He can used his medical training to infect others with diseases or repair himself
* [[spoiler: MyGodWhatHaveIDone: Realized how far off he went and decides to use his skills for the betterment of others]]
* NietzscheWannabe: Doesn't care if humanity is eaten by demons, in fact he welcomed it
* SevenDeadlySins: As one of the Sensui Seven, he represents {{Wrath}} for his extremely violent methods
* TheSociopath: He is paranoid, a liar and had no guilt about hurting others
* PsychoSupporter: Possibly the biggest one, as he fully intends to be killed by demons when they show up

!!''Seaman - Kiyoshi Mitarai''

'''Main Power:''' Water Manipulation]

-->''Humanity only seems good to you because you were born in a peaceful time, but war's our nature, it'll always come back.''

->Voiced by: RicaMatsumoto (JP), Justin Pate (EN)

Kiyoshi Mitarai - codenamed ''Seaman'' - is a human psychic and one of the Sensui Seven. He had a particularly troubled childhood dealing with bullies, which affected him all the more when he watched the entirety of the Chapter Black tape. Kuwabara's kindness, however, ultimately made him defect and help Team Urameshi - [[YouHaveOutlivedYourUsefulness simultaneously making him Sniper's next target]]]. He has the power to mix his blood with water to create powerful golems.
* AxCrazy: Pre-HeelFaceTurn
* {{Bishonen}}
* BloodyMurder: Seaman's power is to create monsters by mixing his blood with water. Which he strangely doesn't use after his HeelFaceTurn, although it can be justified because it needs a large source of water to strengthen it.
* BreakTheCutie
* EvenEvilHasStandards: Was disgusted by Doctor and his intentions, even when they were both part of the Sensui Seven.
* FreudianExcuse: Was savagely bullied in his former school, then Sensui subjects him to watch the Chapter Black.
* HeelFaceTurn
* MakingASplash: Has the ability to animate water to attack people with by mixing his blood in it.
* MoreThanMindControl
* SevenDeadlySins: As one of the Sensui Seven, he represents {{Envy}}.
* VillainousBSOD: The basis for his entire character, from watching the Chapter Black video to discovering people who contradict its contents, it's just one breakdown after another for the poor guy...
* YouHaveOutlivedYourUsefulness: Neither Sensui or Sniper were really bothered with the idea of killing him off immediately the moment Kuwabara took him in.
** UnwittingPawn: That too was a part of Sensui's plan to lure out Kuwabara.

!!''Gamemaster - Tsukihito Amanuma''
'''Species:''' Human Psychic\\
'''Main Power:''' Video Game Materialization]

-->''Hold on to whacha got! Drivin' a REAL car is pretty much like the racing game at the arcade.''

->Voiced by: Yoshiko Kamei (JP), MonicaRial (EN)

Tsukihito Amanuma - codenamed ''Gamemaster'' - is a human psychic and member of the Sensui Seven. He joined Sensui purely because he thought he was "cool for an adult"; meeting someone who apparently liked video games as much as him, and hated the world as much as him. He works together with Gourmet to kidnap Kuwabara. His territory lets him bring any video game to life, altering the physical and logical laws of reality to be the same as that of any game.
* AffablyEvil: Has a [[BrattyHalfPint rather smart mouth]], but is easily the friendliest of the seven.
* CreepyChild: A bratty one
* ChildrenAreInnocent: Sensui plays his naivete and cavalier innocence to manipulate him into joining his cause. Even though he claims to be behind Sensui's plan, it's clear he doesn't process it as real in the way the others do, and though he knows demons are going to be released on the world he doesn't really understand what that truly means - seeing it all as a game (likening the worst thing to happen to being the demons "messing with people" and him getting off of school for a while) [[spoiler: until [[KilledOffForReal he's forced to face the consequences of his actions.]]]] He doesn't even have any ill will towards Team Urameshi, and [[DramaticIrony casually promises to throw the game and let them go]] once enough time has passed and he's had his fun - not realizing at all what that means
--> Amanuma (tearfully): "I didn't mean for all this stuff to ''really'' happen!"
* CurtainsMatchTheWindow: He has brown hair to match his brown eyes in the manga
* HannibalLecture: Tries one on Mitarai during their match to distract him, but Mitarai is able to persist and win.
* [[spoiler:KilledOffForReal: An ''enraged'' Kurama is forced into a situation where he has to kill the child.]]
** [[spoiler:BackFromTheDead: Fortunately, Koenma pulls a few strings.]]
* LockedOutOfTheLoop: While he does know that their plan will kill off the human race, he's either been not told or is too young to understand that the human race '''includes him and his colleagues as well'''
* LonersAreFreaks
* IKnowMortalKombat: In the most literal way imaginable.
* MoreThanMindControl
* TheReveal: Despite his tragic character, this actually serves to be more amusing than anything else as we learn that both Kurama and Genkai are video game nerds.
* RealityWarper: His powers allow him to make video games into reality.
* SevenDeadlySins: As one of the Sensui Seven, he represents {{Sloth}}.
* UnwittingPawn
* VillainousBreakdown: Kurama [[spoiler: reveals that he is going to die]] in order to invoke one of these in him and unnerve him enough to cause him to lose the game. It works, and it's heartbreaking.
* YourSizeMayVary: Just after he is first shown, he drives the truck when the Sensui Seven [[spoiler:kidnaps Kuwabara]]. [[FridgeLogic An elementary school student drove a truck.]]

->Voiced by: Atsushi Ishida (JP), E. Bailey (EN)

Sadao Makihara - codename ''Gourmet'' - is a human psychic and one of the Sensui Seven. He works together with Gamemaster in kidnapping Kuwabara, and later challenges Kurama directly. His territory is inside his stomach, and any person or being he eats lets him absorb their powers. [[spoiler: He ate Elder Toguro, but the latter managed to take over his body]]
* [[spoiler: AssimilationBackfire: Gourmet eats Elder Toguro to get his powers, Elder Toguro ends up taking over his body later.]]
* BreakingSpeech: Strangely fond of these, especially being DumbMuscle and all...
** [[spoiler:Subverted, of course as it's really Toguro talking.]]
* CannibalismSuperpower: When he eats other demons or psychics, he gains their powers.
* [[spoiler: DeadPersonImpersonation: A very dark variant, he ate Elder Toguro, only for the latter to slowly devour him and the realization led him to suicide]]
* [[spoiler:DemonicPossession:When he tries to eat Elder Toguro, the parasitic demon instead ends up taking over his mind and body.]]
* [[spoiler: DrivenToSuicide: In order to escape the terror being EatenAlive from the inside out]]

* ImAHumanitarian: [[spoiler: Ate Murota to gain his {{Telepathy}} power, did the same to Elder Toguro, but it backfired and led to his suicide]]
** MegaManning: He's able to gain the abilities of [[ImAHumanitarian who he eats]]

->Voiced by: Creator/MasashiEbara (JP), Rick Robertson (EN)

Yomi is the newest of the Three Kings--he has a bad relationship with both Mukuro and Raizen, but seeks to unify all three sides and end the squabbling. He was once second in command to Kurama's brigand prior to Kurama ending up into the body of a mortal. Yomi, at the time, was reckless, losing countless men in unauthorized raids and direct confrontation, thinking it more exciting that way. Kurama, angered, sent an assassin to blind him as punishment. Yomi then grew extra ears and tuned his senses so acutely he could eventually hear all within his kingdom. He plans to take over both the demon and human planes in an act of unification, calling on Kurama to his side once again.
* AffablyEvil
* AntiVillain: [[SlidingScaleofAntiVillains Type I]]
* {{Authority Equals Asskicking}}: S+ Class demon
* {{Badass}}: To survive in the demon world, you need some level of this trope. To become one of the ruling powers in demon world, you need to be ''made'' of this trope!
** HandicappedBadass: Was blinded by an assassin hundreds of years ago [[spoiler:sent by his former partner, Yoko Kurama, as punishment for being a LeeroyJenkins]]. To counteract this, he grew four extra ears to allow him to "hear" his surroundings. Despite his blindness, he manages to grow in power from A to S Class, take over a third of the Makai, curbstomp his cloned son Shura in a fight, and [[spoiler:defeat Yusuke during the hero's final fight in the series—credit to Yusuke, though, his fight drained Yomi's Badass tank, causing him to lose in the next round]].
** The most impressive of all his feats? [[spoiler: He manages to force ''[[TheChessmaster Kurama]]'' into an alliance with him, by having one demon threaten to sabotage his parents' honeymoon flight, and having another demon keep track of his beloved stepbrother, all the while flaunting his superior firepower to make sure Kurama doesn't simply try to kill either demon threatening his family or Yomi himself.]] ''MagnificentBastard'', indeed.
* {{Beam Spam}}: Used against Yusuke.
* BloodKnight: Yusuke helps bring this out of him, and Yomi admits that for all his planning and status, he's always wanted to fight against [[AlwaysSomeoneBetter Raizen]].
* CharacterDevelopment: Goes through a lot of it, both on and off screen. Before the series even began he went from a hotheaded glory seeker to a calm, calculating ManipulativeBastard to rival Kurama. Then during the Makai Tournament his warrior's spirit is reawakened, and he decides that he now only wants to achieve his goal of unifying the worlds if he can earn it. [[spoiler: when he loses, he goes on a journey with his son to parts unknown, forsaking his empire.]] It's a lot of growth for a character who appears so late in the series!
* TheChessmaster
* CurbStompBattle: Against Shura.
* DisabilitySuperpower: Yomi has grown two extra sets of ears, giving him six in total. His hearing is so acute that he can hear everything within the borders of his country, hear heart rates spike and decrease, as well as accurately guess facial expressions. Oh, and he can fight just fine. You don't need eyes when you're this guy!
* EvenEvilHasLovedOnes: The reason Yomi was able to win against Yusuke during their CrossCounter was he was able to hear his son's voice encouraging him not to give up. Otherwise it would have been ended in a double KO.
* FriendlyEnemy: He's an [[DesignatedVillain enemy in name-only]], and has no choice but to scheme and manipulate due to the demon realm being a CrapsackWorld, and with all that he still always places emphasis on civility and negotiations before violence and plotting. After his fight with Yusuke, he pulls a HeelFaceTurn and even seems to respect him as a friend and rival of sorts.
* HeelFaceTurn: He wasn't all that evil to begin with, but in the end decides to spend more time with his son than anything else.
* IHaveYourWife: Uses this on Kurama to get his cooperation.
* JerkassFacade: To his son, to make him stronger and more self reliant.
* LeeroyJenkins: He used to be one of these, until he lost his eyes. He seems to imply that he has not once, in a full 1000 years ever again relied on impulse.
* ManipulativeBastard
* NobleDemon
* PyrrhicVictory: [[spoiler:He wins against Yusuke in their match, but gets defeated in the next round because he exhausted himself]].

* [[spoiler: TrulySingleParent: Shura is both his son ''and'' his clone.]]
* WellIntentionedExtremist: Probably the most rational and reasonable of all the kings. He seeks to end the fighting and unify all three realms under a single, stable rule. [[TheChessmaster Too bad no one really trusts him]].
* WorthyOpponent: Views Yusuke as one after [[spoiler:Yusuke finds a way past his DeflectorShields]].
* WouldHurtAChild: Yomi has no problem at all kicking the ever loving crap out of his own son in battle. Although given how much of a cocky smartass Shura is, it's kind of hard to feel sorry for him.

Mukuro is one of the three kings of the Demon realm - despised by Yomi as a " chaos preaching tyrant", somewhat liked by Raizen, but more or less feared by ''everyone'' for being shady and unpredictable. Discovering Hiei while preparing for war and, after testing his strength against Shigure, Mukuro placed him as second in command. Mukuro is quick to agree when Yusuke proposes the demon world tournament, battling with Hiei and winning but then ending up up losing to Enki in the final round.

Raizen is one of the three kings of the Demon World (in fact, he was considered the strongest of the three) and Yusuke's ancestor. After Sensui is defeated, Raizen summons Yusuke to the Demon Realm as he is on the brink of death from starvation and requires someone to take his throne.
* AttackAttackAttack: Combined with CombatPragmatist. If his fight with [[spoiler: Sensui while possessing Yusuke's body]] is any indication, Raizen's fighting style consists of a complete and overwhelming offense, leaving his opponents no chance to properly counter-attack or even defend. During what little is shown of his first "fight" with Yusuke, Raizen delivers another merciless assault, leaving no room or Yusuke to even counter.
* {{Authority Equals Asskicking}}: S+ Class demon
* [[BadassGrandpa Badass Great Grandpa]]: At his peak, Raizen is stronger than everyone in the series!
** According to Yomi's informants, his offensive power is ''still'' the strongest even when almost dead of starvation, and the only reason Yomi and Mukuro can take on him is that his defensive abilities are sub-par due the starvation.
* BigDamnHeroes: During Chapter Black, Raizen [[spoiler:directly intervenes and temporarily possesses Yusuke's body so that he can defeat Sensui. Yusuke was ''mad pissed off'' about this, but when looking at it in hindsight, if he didn't do that, [[OneManArmy Sensui]] would've likely killed Yusuke. ...Again.]]
* CurbStompBattle: His three shown "fights" in the series consist of beating the piss out of [[spoiler:Sensui]], nearly killing Yusuke without even moving, and once again overwhelming Yusuke despite being [[spoiler:literally minutes away from death]]. Only during the third one did his opponent even have a chance at taking him.
* FaceDeathWithDignity: ''After'' going completely berserk first...
** GoOutWithASmile
* GlassCannon: According to Yomi's informants, his offensive power is ludicrously high even by the Three Kings' standards, but the starvation weakened his defensive abilities a bit too much.
** LightningBruiser: Back when he had no problem eating humans, he had enough power to dispatch Yomi and Mukuro simultaneously.
* JerkWithAHeartOfGold: Like his "son".
