Characters: YuYu Hakusho

Has its own page here.

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.

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.

---

• Action Girl: Specifically in the Four Saint Beasts storyline, where she easily fends off possessed people with a baseball bat and then attempts to save Keiko.

• Catch Phrase: "Bingo!"
• Cat Smile: Would often make this face... in every occasion too.

• Cool Big Sis: To the team as a whole.
• Don't Fear the Reaper: Both in apperance (cute and perky) and in role (guide to the after life)
• Genki Girl: Her liveliness and general energy is one reason why Yusuke didn't think she was a grim reaper.
• The Grim Reaper: A pleasant Japanese subversion. Yusuke was expecting the straight version (black robe, sycthe, stoic personality etc.) and that's why he was so surprised to a cute and cheerful girl in a pink kimono.
• Healing Hands: Has this as a limited ability, and uses it on Mitarai at some point.
• Manic Pixie Dream Girl: She fits the personality type (minus crazy impluses) but her relationship with Yusuke was always platonic.

• Ooh, Me Accent's Slipping: 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.

• 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.
• Team Mom: Tends to mother Team Urameshi around. Then again, one of its members is Yusuke of all people.
• Theme Naming: Ferry girls have names based on flowers of which in Botan's case is based on peony.
• You Gotta Have Blue Hair: Or baby blue hair.

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!

Class Representative of Sariyashki High and Yusuke's childhood friend, Keiko is his Love Interest throughout the series.

---

• Action Survivor: Has no supernatural powers to defend herself from demonic and powerful forces. She gets by by being plucky and resourceful, shown especially when she and Botan are up against zombies controlled by insects.
• All Girls Want Bad Boys: Her and Yusuke. Justified 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, therefore she does know his Hidden Heart of Gold very well.
• Armor-Piercing Slap: Especially when Yusuke touches her inappropriately. Yusuke says it hurts more than Kwuabara's punches.
• Belligerent Sexual Tension: Her and Yusuke.
• Brainy Brunette: The invesigator from spirit world says "Her marks are next to perfect."

• Childhood Friend Romance: With Yusuke.
• Childhood Marriage Promise: Played for laughs. Yusuke gives her one right before going to the Spirit World to meet Raizen, she's baffled by it... and then Mr. Yukimura laughs cheerfully and says "he did that every time he gave you grief when you were kids, remember?"

• Distressed Damsel: Not her fault, as it's a consequence of having no magic or spiritual powers.

• Heroic BSOD: Has a pretty big one when Yusuke gets the tar beaten out of him by Younger Toguro.
• I Wished You Were Dead: After being irritated by Yusuke yet again, she furiously snaps "Why don't you just die?!" Shortly after, Yusuke performs his Heroic Sacrifice to save a kid, and Keiko's resultant breakdown is part of what convinces him to work his way back.
• Morality Pet: To Yusuke. Seeing him caring for, and being bossed around by, her shows he's a Jerk with a Heart of Gold.
• Muggle: Keiko and Atsuko are the only characters listed here without any kind of supernatural powers.
• Official Couple: With Yusuke since his revival more or less. Cemented at the end.
• Plucky Girl: Hiei's Shadow Sword, insect-controlled humans, the Dark Tournament...she's been able to handle it all pretty nicely. Borders on Bad Ass Normal 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.
• Spell My Name with an "S": Television closed captions for the English dub spell her name as "Kayko".
• Traumatic Haircut: Averted. Getting parts of her hair singed off after rescuing Yusuke from a fire leads to no angst on her part.
• Tsundere: Often tsun-tsun towards Yusuke (particularly when he's praising her body), although it's clear she does worry about him. The brief dere-dere momments are when he gets out of a particularly dangerous situation. She's a little harsher in the manga.

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

Chief administrator of the Spirit World and son of King Yama, Koenma resurrects Yusuke and becomes his employer.

---

• Bad Boss: Played for laughs as he treats the narrator like dirt.
• Berserk Button: Being laughed off for resembling a toddler.
• Big Good: He is Yusuke's boss and the administrator of the Spirit World.
• Bishōnen: In his adult form.
• Chekhov's Gun: His pacifier is a device that creates a barrier strong enough to hold S-Class demons.
• Chekhov's Gunman: The Chapter Black Saga forces him out of the sidelines, and into the front field for the first time.
• Crossdressing Voices: 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, 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.
• Deadpan Snarker: In his older form.
• Failure Knight: Is extremely guilt-ridden from his involvement and appointment of Sensui. Enough for him to face him personally, and betray his own father.
• He Is All Grown Up / Older Alter Ego: Has a very bishounen adult form.
• Immortal Immaturity: More in the anime than the manga, and usually when he's in his baby form.
• King of All Cosmos: More like prince, but still he's a toddler.
• Mr. Exposition: 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.
• Non-Action Guy: The Koenmatron jetpack is his solution to fighting.
• Oral Fixation: His pacifier. Even as his Older and Sexier Alter Ego, he keeps the pacifier.
• Rage Against the Heavens: 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.
• Really 700 Years Old: 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 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.
• Sexier Alter Ego: Koenma (usually in the form of an infant with a pacifier) is able to take on an older, more bishounen appearance.
• Shout-Out: He is disguised as Tuxedo Mask at the Makai Tournament, probably because Togashi and Takeuchi were dating at the time.
• Spoiled Brat: On his bad days, he'll come off as (particularly) insufferable and bossy, but he's still a fairly responsible leader in general.

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

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.

---

• Action Girl: She is still one of these as a 70+ year-old woman, and, when she was younger, she helped Team Toguro with the Dark Tournament, her being the only girl on that team.
• Affectionate Nicknames: Yusuke calls her an assortment of names ranging from "old hag" to "Grandma." She, in turn, calls him "dimwit," among other things.

• Brought Down to Badass: The li'l ol' hag still manages to hold her own quite well against Doctor's territory. Prior to that, she also took out Suzuki and Shishiwakamaru, two C-class demons, with little effort, as well as became the first character on-screen to actually manage to injure Younger Toguro.
• Brought Down to Normal: 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.
• Chekhov's Gun: Her gaming skills become very useful against one of Sensui's men who can manifest video games into reality.
  Genkai: "What? You think I've been playing Solitaire for the past 50 years?"

• Deadpan Snarker: Sarcastic quips are her specialty, though she laces it with bitter cynicism.
• Gamer Chick: Because she doesn't have much to do when she's not training besides playing some arcade game she owns. Really.
• Healing Hands: Though she doesn't use them often.
• Hidden Heart of Gold: As a Sink-or-Swim Mentor enforcing Training from Hell on Yusuke, she can come across as unfeeling. Well it's clear later on that she cares just as much as anybody else, but don't expect her to show it though.

• Huge Guy, Tiny Girl: With her old friend Younger Toguro.
• I Was Quite a Looker: Was VERY cute when young. Her choosing to be old rather than become a demon like Toguro is what drove him to kill her.
• Killed Off for Real: 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. Unlike the first time she died at the end of the Dark Tournament, she didn't come back.
• Little Dead Riding Hood: Was killed by Younger Toguro in her usual red attire. She recovered.
• Meaningful Funeral: In the manga.
• Meaningful Name: 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 Old Master with a lot of secrets.
• Miniature Senior Citizen: Although she is seen in flashbacks to have always been that height.
• Never Mess with Granny: 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...
• Not So Stoic: Is harsh, disparaging, and domineering to Yusuke to a fault, but almost has an Heroic BSOD when he dies in the Chapter Black saga.
  • Also, she yells at Toguro-ototo when he's literally about to go to Hell.
  • And when he continues to deny she is the same person that fought alongside him 50 years ago, she is VERY UPSET.
• The Obi-Wan: Toguro kills her to make Yusuke stronger. She's revived later by Koenma.
• Old Master: The "just wants a break" version, and badass grandma.
• Paper-Thin Disguise: Doubly subverted. Her disguise is her usual outfit with a head covering bandage. Underneath is her younger appearance.
• Pint-Sized Powerhouse: 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.
• Progressively Prettier: 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.
• Renowned Selective Mentor: 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.
• Self-Deprecation: She's not afraid to make fun of herself in the pursuit of snark.
  Shishiwakamaru: I'm surprised my sword's sound alone didn't kill you, you withered old hag.
  Genkai: Yes, silly me, I must have forgotten to turn my hearing aid on. When you get to be a washed-up old lady like me, the memory is the first to go.
• She's a Man in Japan: In the Filipino dub, she was given the name Jeremiah, which fortunately is unisex, although usually used by males.
• Sink-or-Swim Mentor: "Use your spirit energy to float above the spike."

• Training from Hell: For Yusuke, herself. and the Six Fighters, in the Three Kings arc. For instance, one of her practicies is "Use your spirit energy to float above the spike. We will hold this for twelve hours."

• Vitriolic Best Buds: Yusuke loves and is totally loyal to her. They spend most of their time with him threatening to kill her for all of her Training from Hell sessions and with her telling him in excruciating detail every one of his faults.
• You Gotta Have Blue Hair: Pink hair, which grayed over time.

Go Kuwabara! You can do it!

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.

---

• Beware of the Nice Ones: She once told Hiei her real reason for searching her brother: reminding him his promise to kill all the Ice Maidens and lead him where they lived.
• Body to Jewel: Her tears become valuable jewels, which has people trying to make her cry through incredible cruelty.
• Break the Cutie: She experiences this briefly after watching her only two friends, a pair of bluebirds, get murdered in cold blood.
• Cuteness Proximity: Her very appearance is enough to turn anyone into a doting big-brother and Cool Big Sis who wants to hug her all day long.
• Defiant Captive: She faces torture with as much dignity as she can unless others are threatened/tortured/killed in front of her. Which hits you like a sack of bricks when you think of how long the poor girl has been tortured until the point of desensitization.
• Friend to All Living Things: 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 Whole Episode Flashbacks has her make an interesting statement...which makes her a subversion of the trope, if anything.
• Healing Hands: But not The Medic. Her powers are good, but she doesn't appear often enough for that.
• Huge Guy, Tiny Girl: With Kazuma who is easily twice her size.
• An Ice Person: She's a lot nicer then Seiryuu at least.
• Implied Love Interest: Of Kuwabara by the end of the series.
• I'm Taking Her Home with Me!: 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 Kuwabara's family does take her home, whether as a little sister or as Kazuma's girlfriend/wife is left uncertain.
• The Ingenue: Kind, innocent, gentle, etc.
• Maybe Ever After: With Kuwabara.
• Mercy Kill: 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."

• Protectorate:
  • Of Kuwabara. Raising a hand to her is a very good way to cause Kuwabara's instant Unstoppable Rage.
  • Also of Hiei. In the second movie, one of the villains admitted having harmed her, and Hiei disintegrated him. Then there's his Cruel Mercy to Tarukane...
• Red Eyes, Take Warning: Averted. She has deep red eyes yet she's anything BUT evil. Then again, she's searching her brother to have him commit a genocide...

• Separated at Birth: With Hiei. So separated that he was thrown off the Ice Demon's floating city few hours after he and Yukina were born, despite their mother's cries and pleas to get him spared.
• Will They or Won't They?: Her and Kuwabara. And the finale keeps the status quo even though there are some hints that Yukina just might reciprocate.
• Woman in White: She always shows up dressed in a pure white kimono.
• Yamato Nadeshiko: In both appearance (long hair, kimono, moderate height) and personality (dignified, strong willed, polite, loving) and just might have become Kuwabara's wife at the end.
• You Gotta Have Blue Hair: Sea green in this case.

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

Yusuke's alcoholic mother, unaware of his Spirit Detective job.

---

• Absurdly Youthful Mother: Was only 15 when Yusuke was born.
• Alcoholic Parent: She is almost always shown drunk, and more than once toasted to the point of sleeping in.

• Aww, Look! They Really Do Love Each Other: She may not be the most responsible parent, but she genuinely cares for Yusuke.
• Demoted to Extra: 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.
• Does Not Like Shoes: She never appears to wear any in the anime. In the manga as she also wears her business attire from time to time.
• Dragon Lady: 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.
• Hard-Drinking Party Girl: She often draws others in.

• One of the Boys: Her pals outside of Yusuke's circle in the manga are men.
• Parents as People: While she does clearly love her son, she is just as clearly unprepared for motherhood.
• Stacy's Mom: Kuwabara's gang certainly seemed to think she is a hot mom.

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

Kuwabara's Deadpan Snarker sister, even more spiritually aware than him.

---

• Action Survivor: The girl isn't a fighter, but manages to survive this very action-packed story. That's pretty badass in itself.
• All Girls Want Bad Boys: Her and Sakyo in the anime. Though she's Genre Savvy enough to not harbor any 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 subverted due to just being his looks.

• Big Sister Bully: She's sometimes abusive towards her brother.
• Cool Big Sis: actually Kuwabara Kazuma's older sister, who seems to consider it her job to keep the younger (acting?) girls safe and upbeat.

• Education Mama: In the final arc, puts pressure on Kuwabara to study, which results in him getting into a good high school, albeit barely.
• Hidden Heart of Gold: She does care about her brother, but you're not gonna find her admitting or showing that any time soon.
• It Runs in the Family: Has a high spiritual awareness like her brother.
• Psychic Powers: Is much more powerfully clairvoyant and can actually see ghosts.
• Smoking Is Cool: She even puts her cigarette out on an apparition's tongue to shut him up.
• Tragic Keepsake: Sakyo's lighter.

A shinigami like Botan whose primary duty in Spirit World seems to be doing research for Koenma.

---

• Aloof Dark-Haired Girl: As can be seen here.
• Demoted to Extra: She is one of Koenma's chief assistants in the manga. In the anime, her only appearance was in Episode 66 to provide a summary of Younger Toguro's life for him to decide on his fate in the afterlife.
• Kimono Is Traditional: She always shows up in her black kimono, and unlike Botan she never changes into anything else.
• Love Interest: In the manga, Koenma is shown to have an infatuation for her. Whether she has any feelings for him in return is ambiguous.
• Theme Naming: As with her fellow Ferry girls, her name is based on that of a flower. In Ayame's case, hers is iris.
• The Watson: She is the one who primarily serves as this in the Manga, but gets replaced as this by Ogre in the anime.

A Yusuke's Spirit Beast who hatched from the egg given to him by Koenma.

---

• Bond Creature: Yusuke received an egg that would hatch a spirit beast. If he's good it will be this. If he isn't, the beast will eat his soul. The egg would have been the latter but he sacrificed it to save Keiko. Thus because of this, it ends up hatching a good spirit beast, Puu. The nature of the creature produced was supposed to be determined by the type of energy Yuusuke gave off. If bad, he'd get eaten and the filing problem he represented would be over; if good, he'd earned resurrection. But then scheduling issues caused Koenma to ditch that plan and just resurrect him, and the egg presumably hung around in spiritual form being ignored until ready to hatch. Puu originally resembles a blue Furby with huge floppy ears, but evolves into a sort of phoenix thing after Yuusuke is resurrected again as a Mazoku.
• Cessation of Existence: What it could have done to Yusuke had it hatched earlier.
• Chekhov's Gun: The egg Yusuke throws into the fire to save Keiko early in the series is Puu! It gets lampshaded when Koenma has to remind Yusuke about the egg during the Dark Tournament arc, as he'd completely forgotten about it after he came back to life.
• Empathy Pet: Whatever Yusuke is feeling, Puu will also feel and vice versa.
• Foreshadowing: During the final match against Toguro Yusuke's spirit energy takes the form of a giant bird and flies around the stadium before it settles back into him, foreshadowing the form Puu (who is a representation of Yusuke's spirit) will eventually take. (Puu also settles down around Yusuke right after taking that form, just like the energy did.)
• Head Pet: Until he was too large to stay on Yusuke's head.
• The Phoenix: His true form.
• Synchronization: With Yusuke by virtue of being his bond creature.

I need a new job…

Koenma's ogre assistant, often blamed and bullied by him.

---

• Ascended Extra: His first appearance was as one of several Ogres trying to get paper work to Koenma during the Genkai Tournament arc in which he provides some small amount of commentary. He made his next appearance during the Maze Castle arc unaccompanied by any other ogres and the rest is history.
• Butt Monkey: He gets abused by Koenma even when he doesn't do anything.
• Canon Foreigner: Doesn't appear in the manga, where his function is usually served by Botan or Ayame.
• Narrator All Along: 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 Funimation as "Ghost Files").
• Only Known by Their Nickname / No Name Given: 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 "you" before that.

• The Watson: He exists purely for Koenma to abuse and explain things to.

A Ferry girl that is featured in the movie "Bonds of Fire"/Poltergeist Report.

---

• Canon Foreigner: She was created specifically for the movie.
• Idiot Hair: She has an ahoge that is long enough that it bends back, however she isn't dumb. A Ferry girl in training yes, but not stupid.
• Miko: She wears an outfit that resembles one that would be worn by a Shinto Shrine Maiden (AKA Miko).
• Ms. Exposition: Serves as this in explaining the backstory regarding the Spirit World vs Netherworld war that occurred eons earlier.
• Theme Naming: She continues this trend of Shinigami having names derived from flowers. Hinageshi's name translates into English as "Poppy".
• You Gotta Have Blue Hair: Blood red hair in her case.

Toya

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?

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.

---

• The Ace: Considered to be the greatest ice master alive.
• Badass: Very tough customer.

• Friendly Enemy: In his fight with Kurama.
• An Ice Person: A demon ninja with mastery over ice. When he went under Genkai for some Training from Hell, he became powerful enough to freeze a battlefield.

• Let's Fight Like Gentlemen: In the first tournament he openly objects to his team leader's dirty tactics.

• You Gotta Have Blue Hair: Ice blue hair with pale green bangs.

Jin

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

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.

---

• Blood Knight: Jin loves to fight just as much as Yusuke.

• Cute Little Fangs: See here◊

• Friendly Enemy: Very! He and Yusuke get along remarkably well.
• Keet: This is not helped by the fact that he has the same Japanese voice actor as Ryuichi Sakuma.

• Oireland: in the English dub, speaks with a nearly impenetrable Irish accent for some reason.
• Worthy Opponent: Views Yusuke as one.

Chu

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!

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.

---

• The Ace: To his team.
• Addiction Powered: The drunker he gets, the stronger he becomes.
• Authority Equals Asskicking: 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 Rock-Paper-Scissors. He soon proves his strength soon enough.
• Blood Knight: When Yusuke tells him he wants to see if he has more than his drunken fist, he gets very interested
• Boisterous Bruiser: He's by far the tallest guy Yusuke hangs out with, he drinks like a fish and only becomes that much stronger when he does it. Helped by who voiced him as well.
• Casanova Wannabe: Shown in his Establishing Character Moment with Koto (the cat commentator). He mellows out a bit later on, mainly directing the unwanted affections toward his Ice Queen love interest.
• Crouching Moron, Hidden Badass: 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.
• Drunken Master: 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?)
• Friendly Enemy: Right up there with Jin as one the friendlier opponents Yusuke faced though this was probably due to their mutual Blood Knight tendencies in the beginning. During the Three Kings saga later on however, he and Jin did share hugs and laughs with the latter upon being reunited.
• Heel-Face Turn: Though let's be fair, it's not like he was that evil to start with.
• Large Ham: What did you expect of Norio Wakamoto? And surprisingly enough, Kent Williams manages to up the ante with a hammy Australian accent!
• Love at First Punch: With Natsume.
• Wild Card: He appears without any foreshadowing, and gives Yusuke who had taken training what was intended to be a Curb-Stomp Battle and change it into an equal fight. Even their sponsor lampshades it.
• Worthy Opponent: Views Yusuke as one.

Rinku

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

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.

---

• Creepy Child: Very creepy, at first. It faded away with time. After befriending Team Urameshi, he stopped the psychotic grins.

• Enfante Terrible: He started off as a sadistic opponent who enjoyed every bit of the Curb-Stomp Battle he was giving Kuwabara.

• Killer Yoyo: Rinku can control four yoyos in each hand and each one attacks independently of the other and obey his will. After his Trainingfrom Hell, he can use eight yoyos.
• Likes Older Women: Though its hard to tell his age, he did have a crush on a taller and teenage looking demon.

Shishiwakamaru

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

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.

---

• Affectionate Nickname: Occasionally called "Shishi" for short. Suzuka tends to use it a lot in the final arc, particularly when Shishiwakamaru's life is briefly in danger during the tournament preliminaries.
• Apathetic Citizens: Is the only one of Kurama's Six Fighters to not express much passion in the Yusuke vs. Yomi debate, instead marking his vote as "undecided". Suzuki is quick to scratch out his vote and change it to "Yusuke".
• Big Bad Wannabe: For a minute there, it really looked like he'd be the next tough opponent. ...He wasn't.
• Heel-Face Turn: Once retconned into surviving his battle with Genkai.
• It's All About Me: He sort of acts like a celebrity and is obsessed with fame.
• Make Me Wanna Shout: 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 Tournament Arc, 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 Minamoto-no-Yoshitsune, aka Ushiwakamaru, the samurai that was said to originate the term Bishōnen.
• Sleep Mode Size: 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.

• Split Personality: Shishiwakamaru fluxuates between a smug warrior and a bloodthristy berserker.
• Team Prima Donna: To both Team Uraotogi and the Six Fighters.
• Villainous Breakdown: Shishiwakamaru goes ballistic once he realizes Genkai has the upper hand in their fight.

Onji / Suzuka / Suzuki

Better watch yourself, simple human boy. It's against Spirit World law to say my name without putting a 'beautiful' in front.

A crafty and mysterious old man who's the true leader of Team Uraotogi. No one's really sure who he even is, or what his real game is...

---

• Boisterous Weakling: Summed up by Genkai that while he had plenty of tricks that helped him win fights, it was all a smokescreen to hide the fact that he had jack in terms of genuine strength or firepower. She punctuated the fact by beating the crap out of him.
• Curb-Stomp Battle: After Shishiwakamaru was efficiently disposed of, then it looked like this guy would be the next tough customer... He was even weaker.
• Eviler Than Thou: Backed down scared rather than face Toguro at a fraction of his full strength (to clarify, Toguro was only powered at 3%).
• The Fighting Narcissist: Such is his vanity that he'd actually prefer to be made a legend without his face being shown, so those in the future would forever wonder how "the beautiful Suzuki" looked.

• Insistent Terminology: Suzuka demands to be addressed as "the beautiful," and throws a razor playing card at one of the commentators, decapitating an audience member behind her, when she fails to call him that. Also blasts a portion of the stadium that mocked him for not using this. He still insists on this, even after his Heel-Face Turn.

• Joke Character: Both figuratively and literally, haha. When his true form is revealed, even the demon audience is embarrassed. Keep in mind, the people who have spent the entire tournament calling for Team Urameshi's heads on a pike are so turned off by a flamboyant clown demon that they openly say that they have no idea what team to hate more.
  Hiei: This idiot makes Kuwabara seem smart.
  Kurama: I admit, I'm embarrassed listening to him.
• Took a Level in Kindness: Unlike Shishiwakamaru, who switched to the side of good while maintaining his prima donna attitude, Suzuka seems to be a lot more dedicated to Team Urameshi's cause following his defeat. He starts out by giving Kuwabara and Kurama vital devices to help hone their energy for the fight against Team Toguro, and then is quick to express his support for Yusuke alongside Rinku, Chu, Jin, and Toya when Kurama asks how they feel about Urameshi facing off against Yomi (their boss). He even goes so far as to enthusiastically override Shishiwakamaru's vote of indifference on the matter, forcing the latter to side with Yusuke like the rest of them.
• The Trickster: He's actually very powerful and tricky. He just has no Godamn idea how to properly use that power...
• True Companions: Appears to have this feeling with Shishiwakamaru, showing genuine fright when he thinks the latter was killed after getting swallowed whole in the preliminary round for the final tournament. The sight literally causes him to freeze up onscreen.
• Villainous Harlequin: Suzuka, who would be a Monster Clown if he wasn't such a source of comic relief. At least until his Heel-Face Turn.
• Weak, but Skilled: He has an amazing capacity for spiritual energy—unfortunately, he thought this was enough to make him strong. Grows out of this after his Heel-Face Turn.
• Writing Around Trademarks: Suzuki was renamed Suzuka for the dub, so as to not offend the car company. He was changed back to Suzuki in the Blu-Ray re-dub.

Yu Kaito

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

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.

---

• Badass Pacifist: 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.
• Badass Bookworm: While he's not exactly a fighter, he can keep his wits when 'fighting' others and is very, very booksmart.
• Hoist by His Own Petard: His taboo power also applies to him.
• Insufferable Genius: A villainous one at first, which probably came with the whole "evil act" business.
• Meaningful Name: Yu means ghost and Kaito means thief. One can only wonder why he steals the souls of up to three of our main characters.
• The Problem with Pen Island: 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 "each other" for "hot".
• Reality Warper: His territory bans violence and imposes linguistical taboos which must be cleared.
• The Rival: Academically, to Kurama.
• The Scottish Trope/Words Can Break My Bones: If you say the Taboo word, you lose your soul.
• Secret Keeper: He is the only human who knows Kurama's whereabouts in the last arc.

Asato Kido

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

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.

---

• The Bus Came Back: The doctor likely healed him.
• Couldn't Find a Pen: Uses his Shadow for this to tell Yusuke that Kamiya is the Doctor.
• Curb-Stomp Battle: As Genkai 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.
• Knight of Cerebus: 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.
• Nice Guy: He's actually the nicest member in the group, despite appearing to be a tough thug.
• Put on a Bus: Spends most of the Chapter Black saga offscreen in the hospital.
• Redemption Demotion: Beaten up by Murota and paralyzed by Doctor within two episodes. (Not that he was really so bad before...)
• Shadow Pin: 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.

Mitsunari Yanagisawa

So you picked my pocket with some greenery? You really are a first class freak!

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.

---

• Dare to Be Badass: During Yusuke's fight with Doctor he manages to burn Doctor with chemicals.
• '80s Hair: That's some epic hair, man.
• Master of Disguise: As said above, his psychic powers allow him to adquire someone else's looks, memories, skills, etc. after touching him or her.

Shigeru Murota

I don't have any heroic aspirations. I'm much more interested in starting my fighting career.

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 Tapping, which allows him to read the minds of anyone in a 30 mile radius. He's eaten by Gourmet after Kuwabara was captured

---

• Boxing Battler: Is a boxer. His mind reading power gives him a distinct advantage in fights, albeit not nearly enough to beat Yusuke.
• The Chew Toy: Punched out by Yusuke, shot in the head by Sniper as intimidation, and infected by the Doctor's disease all within the space of three episodes.
• Combat Clairvoyance: Seeks to use his mind reading skills to become a successful professional boxer.
• Dare to Be Badass: During Yusuke's fight with Doctor he reads the Doctor's mind to save Yusuke from his bluff.
• He Knows Too Much: He's killed by Gourmet for both his ability and that he knew too much about the plan.
• Heroic BSOD: Has a full-blown psychotic breakdown after reading Sensui's mind.
• Killed Off for Real: He is eaten by Gourmet right after Kuwabara was kidnapped.
• Not What I Signed Up For: Says this after reading Sensui's mind and being shot by Sniper.
• Telepathy: His power.

Hokushin

You are my king now! I am sworn to protect you!

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. Impressing Yusuke in a fight, Hokushin goes back to demon world waiting for Yusuke's arrival so they can get to training. When Yusuke arrives, he begins training and preparing him towards his true destiny.

---

• Bald of Awesome: As said below, he's incredibly badass. And has no hair on his head save for his brows.
• Badass: He is an S-Class demon. His debut even has him beat Yusuke in fight.
• Cool Old Guy: He doesn't exactly look like it, but he's several centuries old and is a pretty chilly guy when you get to know him.
• The Dragon: Initially to Raizen. Later becomes Yusuke's right-hand man.
• I Am A Humanitarian: During their initial fight Yusuke states he smells humans on Hokushin's breath.
• Manly Tears: Cries these during the Yusuke and Yomi's fight.
• The Mentor: To Yusuke once he arrives in Demon World although Yusuke quickly surpasses him.
• Not So Stoic: When Yusuke used all of Raizen's treasury to suggest the Makai Tournament, Hokushin freaks out.
• The Rival: Initially to Yusuke during the Three Kings Saga but quickly becomes more of a mentor figure to him.
• Rubber Man: Hokushin's main power used effectively in his fights.
• The Stoic: Everything he says he says with a straight face on.
• Undying Loyalty: To both Raizen and Yusuke.

Jyaki

The subject of Yusuke's very first case as Spirit Detective. He possessed a human teenager named Sakamoto who black mailed Kuwabara to do what he wanted and break his honor code in the process on the pain of harming and/or killing Eikitchi, Kuwabara's pet cat.

---

• The Corrupter: He is able to take control of other's minds and influence their dark side into committing evil deeds.
• Demonic Possession: His specialty.
• Horned Humanoid: Jyaki has a pair of horns which also manifest on the hosts he possesses (though only those with Spiritual awareness can see them).
• The Imp: So small that Yusuke could hold him in his hand.
• Orifice Evacuation: Jiaki is shown escaping Sakamoto's body via his mouth.
• Starter Villain: He is the very first demon that Yusuke encounters upon being resurrected.

Goki

Do you know what the best spices for a soul are? Some fear and a dash of pain.

A collaborator with Hiei and Kurama to steal the Artifacts of Darkness from the Spirit World Vault.

---

• The Brute: Serves this role for Hiei and Kurama.
• Child Eater: Or then at least eats their souls, which he says tastes like candy.
• Death by Irony: Gouki who eats souls for a living dies by taking a blast of spirit energy into the mouth.
• Does This Remind You of Anything?: Goki's soul-eating tastes (that of little children) is rather close to the edge of pedophilia.
• Dumb Muscle: Which brings about his own undoing.
• Lack of Empathy: Especially when it comes to eating children's souls.
• Nigh Invulnerable: Nothing Yusuke could do at the time could penetrate his skin. Goki's mouth and insides on the other hand....
• Serial Killer: He was said to have committed six murders prior to taking part in the heist.
• Underestimating Badassery: Upon seeing Kurama, he snidely dismisses him as not being the great Yoko Kurama he has heard of. Kurama then quickly cuts down several trees around him and Goki bites his tongue back after that.

Rando

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

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.

---

• Awesome but Impractical: 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. It can even be deflected back to the user if the technique is used with no one else around to hear the chant.
• Crossdressing Voices: In the Japanese version.

• Fatal Flaw: He is so obsessed with the power of techniques, he doesn't bother to learn their weaknesses and how they can backfire.
• Hoist by His Own Petard: The Shrinking curse backfires on him.
• Mega Manning: Steals other martial arts masters' techniques.
• Not-So-Harmless Villain: His scores on the tests are barely high enough to pass, but he turns out to be the strongest opponent Yusuke faces.
• Playing with Fire: One of his stolen abilities.
• Psychopathic Manchild: More obvious in the Japanese version.

• Shark Pool: Hangs Yusuke over a pond of piranha-like fishes.

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.

---

• Bishonen Line: The stronger the Beast, the more human they are.
• Elemental Powers: Genbu can control the stones that make up his body, Seiryuu can manipulate ice and Suzaku is able to use lightning. Byakko is just a tiger man who can fire beams from his mouth and create creatures from his hair.
• The Four Gods: Each of them have an obvious design theme that makes them related to that specific god.

• Knight of Cerebus: The first enemies that have their own teammates killed, and to be killed through determination rather then dumb luck.

Genbu

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

A rock demon with the power to move through stone as though it were part of his body.

---

• The Brute: Fights with one trick through brute force.
• Dishing Out Dirt: More like made of dirt.
• Elemental Embodiment: He's more of a golem.
• The Four Gods: With his shell and reptilian features, he's like demon throwback to gargoyle turtle man.
• Home Field Advantage: 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.
• Monstrosity Equals Weakness: Looks like a turtle Kaju with a troll face, but had the second swiftest defeat,
• Pulling Themselves Together: Does this, but epically backfires in a real funny way.
• Rock Monster: 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.
• Smug Snake: Believes he's going to win and that his power has no flaws, leading him to plead with his opponent not to kill him.
• Tag Along Kid: 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.

Byakko

Humans! I will rip you apart and eat you myself!

An anthropomorphic white tiger who can turn pieces of his hair into lesser beasts, absorb aura energy and fire sonic blasts from his mouth.

---

• Alas, Poor Villain: 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.
• Et Tu, Brute?: He is genuinely shocked when Seiryu decides to kill him for his failures.

• Fair Play Villain: He's straightforward compared to hide and seek Genbu, ruthless Seiryuu and wicked Suzaku.
• Feed It with Fire: He can absorb spirit energy, becoming bigger in the process.
• The Four Gods: Represents the White Tiger.
• Genius Bruiser: Although he is just muscle like Genbu, he employs a lot more moves and wit.
• Made of Iron: He survives falling into lava, but is grievously injured.
• Make Me Wanna Shout: His "Tiger Scream" disintegrates anything it hits.
• Monstrosity Equals Weakness: Averted in that he's tougher than Seiryuu.
• Panthera Awesome: A white tiger man.
• Petting Zoo People: A tiger man.
• Rasputinian Death: Falls from a great height, falls from a great height into lava, but is then ultimately only killed by being frozen and shattered
• Smug Super: He views himself highly with justified reason, seeing that he has a powerful Make Me Wanna Shout 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.
• Sympathy for the Devil: You must be doing something right, when Hiei feels sorry for you.

Seiryuu

It is not wise to insult your executioner.

A demon with enhanced speed and control over ice.

---

• Arrogant Kung-Fu Guy: Even looks like a martial artist.
• Curb-Stomp Battle: Cut into many pieces by Hiei almost instantly.
• The Dragon: Which is fitting.

• The Four Gods: He'd be the dragon...though he's just a big blue skinned man with a dragon outfit. Yu Yu Hakusho Abridged so Lamp Shades this.
• An Ice Person: Fragile enough to the point that one blow is enough to defeat, and one can do it through ice punches
• Kick the Dog: Killing Byakko for failing, the fact that he tried asking for help and genuinely shocked at the betrayal makes it worse
• Single-Stroke Battle: Hiei kills him in 16 slices.
• Smug Snake: Confident, but too sure of his technique.

• You Have Outlived Your Usefulness: To Byakko, and anyone who is of no further use to the Saint Beasts.

Suzaku

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

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.

---

• 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.
• Big Bad: Of the Saint Beasts Saga.
• Bigger Bad: Of the Spirit Detective saga.
• Bishōnen: Fits with the Bishonen Line theme that the Saint Beasts are going for.
• Cold-Blooded Torture: Suzaku is a massive sadist who sits on his chair while his clones electrocute Yusuke, six on one.
• Doppelgänger Attack: Like mentioned above, seven clones, each just as strong as him.
• Faux Affably Evil: 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 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 mind controlled minions were about to kill Keiko and Botan; all the while enjoying himself like he is watching his favorite horror film.
• The Four Gods: He'd be the Phoenix, especially since he can revive himself mutliple times and has a bird for a companion.
• Genre Savvy: His scheme (especially regarding Keiko) is set up like a B-grade horror movie. That isn't lost on him in the slightest.
• Manipulative Bastard: 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.
• Morality Pet: Murugu, though she's as gleefully sadistic as he is, she's still the only thing he's shown to care for.
• Musical Assassin: uses the flute to control insects, but never uses it in combat for obvious reasons.
• Night of the Living Mooks: His cultivated humans.

• Shock and Awe: Uses it as arrows or shocking his enemies to death.

Half Breed Demons

Not!Kuwabara: To make your name in this world is a hard job indeed!

Not!Yusuke: For half Youkai like us who have a registered name and citizenship in Ningenkai.^note  In the YYH-verse, Ningenkai refers to the Human world.

---

• Adapted Out: They don't appear in the anime.
• Criminal Doppelgänger: Their Human forms have a strong resemblance to Yusuke and Kuwabara as can be seen here.
• Evil Redhead: Not!Kuwabara.
• Glory Seekers: They seek to bring about Yusuke and Kuwabara's demises in order to make a name for themselves.
• Half-Human Hybrid: As their de facto name shows, they are Demon-Human hybrids.
• Mundanger: Double Subversion. While they have Demon ancestry, they are incapable of doing any sort of supernatural abilities and thus have to rely on their own wits and an army of low level Demon-Human hybrids cohorts.
• No Name Given: Their names are never revealed.
• Opportunistic Bastards: They attempted to take advantage of Yusuke and Kuwabara's weakened states from having fought against the Saint Beasts to frame them for sneak attacks so that other gangs will seek to fight and potentially kill them.
• Time for Plan B: In the event that things went awry (which they did once Kurama exposed their ruse), they had recruited an army of fellow half breeds to aid them. However, Hiei already took them out leaving them at the mercy of the angry mob. Cue Oh, Crap.

Gonzo Tarukane

The Founder of the Black Book Club.

---

• Asshole Victim: Thanks Toguro for giving him what he deserved.
• Big Bad Wannabe: While he is dangerous thanks to his wealth and his connections (being the founder of the Black Black Club, and hiring various demons and humans to do his dirty work), he overestimates his chances of winning, loses everything when Younger Toguro is defeated, and doesn't compare well to most of the antagonists in the series. It doesn't help that The Toguro Bros were actually working for the real Big Bad, who had caused him to lose his money, and that they end up killing him after this is revealed.
• Collector of the Strange: He has a personal zoo of demons in his possession.
• The Don: Though Oyabun might be more appropriate given his Japanese nationality. To emphasize this, in the Filipino Dub his name was changed to "Don Paquito''.
• Gonk: Discussed in this exchange when the Heroes see an image of him for the first time.
  Kuwabara: He's too ugly to be a Human.
  Yusuke: He's too ugly to be anything.
• Smug Snake
• Villainous Glutton: Gonzo Tarukane is fat, ugly, and has a satisfying death scene.
• Villainous Legacy: Though he isn't around for long and only appears in the Spirit Detective Saga for a few chapters/episodes, his actions via the founding of the Black Book Club and its Demon trafficking operation puts into motion much of the series and also leads Sensui to believe that Humans must be destroyed.

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, life would be more interesting that way.

---

• 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.
• Badass Crew: With the exception of Sakyo and Elder Toguro, each is a major Person of Mass Destruction in their own right
• Lovecraftian Super Power: Each one, with the exception of Bui and Sakyo, manifest their powers in a disturbing and Creepy Awesome kind of way.

Younger Toguro

Please be gentle with us. We're very fragile.

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.

---

• '80s Hair: A flat-top no less!
• Affably Evil: A honorable fighter and only kills when required to, unless you prove to be a worthy opponent.
• The Ageless: Became this upon becoming a Demon so that he would never experience declining strength with age as well as preventing those he loved from ever being victims of the likes of Kairen.
• And I Must Scream: Chooses to be sentenced to the lowest pit of hell where he will be tormented for thousands of years then simply cease to exist, even though he could have received a lighter punishment.
• Anti-Villain: Despite a steady stream of brutal actions under his belt, thoughts of redemption are in the back of his mind and he is honorable, with a Freudian Excuse.

• Badass: Oh yes. Koto lampshades it, calling him the Dark Tournament's resident badass.
• Blood Knight: Dislikes fighting weak opponents, but fights them anyway because it's a fight after all. When Yusuke attempts to beat the crap of Toguro for killing his one decent teacher only to lose instantly, Toguro is a little too happy that Yusuke is able to break his hand. His whole reason for Stealth Mentoring Yusuke is that he's looking for someone who can allow him to fight at 100% strength.
  • Once Yusuke doesn't give him a challenge, he goes to kill one of his friends to get him to be more serious.
  • Also qualifies as a Deconstruction as he no longer has any satisfaction in his life outside of fighting.
• Cool Shades: Almost never seen without them. It's only at the very end of the Dark Tournament that we see his eyes.
• Curb-Stomp Battle: Dishes them with each percentage necessary to defeat the enemy at hand.
• Cynicism Catalyst: His students' murder at the hands of Kairen is what caused him to Took a Level in Cynic.
• Deadpan Snarker: And not exactly subtle about it, either.
• Deal with the Devil: Combined with He Who Fights Monsters when he defeats Kairen (a demon who had much the same abilities as the Toguro Brothers) at the Dark Tournament 50 years ago, and upon winning asks the Tournament Commitee to turn him and his brother into demons.
• Death Seeker: He wants to die at the hands of a stronger fighter.
• The Dragon: To Sakyo.
• Dragon-in-Chief: But he is much more dangerous than his boss.
• Dragon with an Agenda: He's a Death Seeker and thus hopes not to win the Dark Tournament. That doesn't fit well with Sakyo's plan.
• Even Evil Has Standards: Still finds some actions completely distasteful, especially those of his older brother.
• Evil Counterpart: To Yusuke; whereas Sensui is Yusuke's exact opposite, Toguro is more what Yusuke would become if he decided to abandon his good tendencies and love for his True Companions and gave in to his inner Blood Knight. Even his coat is olive green, a darker shade to Yusuke's usual outfit, Not to mention, they also share a Deadpan Snarker trait.
• Fallen Hero: He fought evil demons and taught disciples to fight evil...then Kairen showed up and his beliefs were shattered.
• Finger Poke of Doom: He can make peoples heads explode by simply tapping on them, which sounds suspiciously familiar.
• Genius Bruiser: Despite being muscular, he is a Warrior Poet and a Deadpan Snarker, it's just that it's only limited to fighting.
• Healing Factor: Not to the same extent as his brother, but can regenerate a gaping hole in his body in seconds.
• Hell Seeker: He is a Death Seeker so he can go to the deepest pit of hell so he can be eternally punished for not having the strength to protect his disciples.
• He Who Fights Monsters: Started off a martial artist fighting demons, but ultimately became one.
• Huge Guy, Tiny Girl With his old teammate and friend Genkai.
• Humanoid Abomination: Especially at 100%.
• Immortality Seeker: In his past, though Eternal Youth Seeker is more accurate. He comes to regret that wish.
• The Juggernaut: 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.
• Kick the Son of a Bitch: 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.
• Last Name Basis: His given name is never mentioned, he's only known as the younger of the Toguro brothers.
• Lightning Bruiser: Unlike most beings of his stature, Toguro is every bit as fast as he is strong and muscular, even at his maximum.
• Muscles Are Meaningless: A complete subversion. As he powers up, he becomes incredibly muscular in the process.
• My Greatest Failure: Not protecting his students from Kairen, a powerful demon. Even after defeating Kairen in the previous Dark Tournament, he never let it go, turning himself into a demon and later going to the deepest level of Hell in order to punish himself for this.
• Never Be Hurt Again: One of two reasons (see also Survivor Guilt) why he made a Deal with the Tournament committee was so that he could never again be powerless.
• Nineties Anti-Hero: Deconstructed. Ridiculously muscled and possessing tremendous power? Check. Cold, aloof son of a bitch with little care for others? Check. No inhibition to destroying anyone he is ordered to kill and/or needs to be killed to fulfill his goals. Check. Though the "Hero" Part? He is a Fallen Hero who made his Deal with the Devil with the intention of using his new found eternal youth to avoid being powerless to stop massacres like the one that cost his students' their lives. However he gradually became more jaded in his outlook and lost faith in his mission upon realizing he had become no different from what he sought to destroy.
• Noble Demon: He's only in it for business and will only be brutal when it's necessary, in contrast to his sadistic brother.
• No-Holds-Barred Beatdown: Most of his fights are Curb Stomp Battles, but his fight in which he kills Genkai was nothing but vicious as he goes for her heart and No Sells all of her remaining energy blasts before finally killing her by breaking her spine with his fist at 80%. It gets worse when Toguro goes 100% against Yusuke: the fight becomes so one-sided that it takes 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. it's so bad that the REAL Keiko snaps and loses consciousness.
• Not So Stoic: when he goes 100%.
• One-Winged Angel: At 100% strength he becomes a gray-skinned monstrosity
• Sinister Shades: Throughout most of his appearances.
• Spirited Competitor: Does not like fighting weaklings at all, but is very excited when Yusuke can provide a challenge to him.
• Start of Darkness: He went insane after a demon killed his students, and even after killing him, he felt that he needed to be punished for it for all time.
• Stealth Mentor: towards Yusuke, he pushes Yusuke to be stronger and his words during his fight with Yusuke seem to a Secret Test of Character in hindsight, so he won't be completely consumed by battle.
• The Stoic: One of his most notable attributes is his constant poker face.
• Survivor Guilt: His inability to save his disciples from being killed by Kairen is the source of his motivation for his actions.
• Sympathy for the Devil: His Freudian Excuse definitely earns this.
• Tragic Villain: His whole backstory and motivation, even if he has little Pet the Dog moments.
• Unskilled, but Strong: Subverted. He's a very skilled martial artist—he just prefers relying on absolute strength rather than doing flashier energy attacks.
  "The strength to make all tactics useless. That is strength absolute."
• Up to Eleven: 100% of 100%.
• Walking Shirtless Scene: 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 his nice coat.
• When All You Have Is a Hammer: Notes that brute strength is the only thing he's really good at, but manages to get by with that, beating everyone that got in his way.
• Who Wants to Live Forever?: He certainly didn't want to by the time the story began.
• With Great Power Comes Great Insanity: The more he uses his power, the more his bloodthirsty urges seep out.
• Worthy Opponent: Views Yusuke as one as well as the one to end his miserable existence.

Elder Toguro

My mom always wanted me to become a surgeon. It's a pity I played hookie the day we dissected frogs. Oh well...

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 Sakyo's standards.

• The Dark Chick: Unlike his teammates excluding Sakyo, his acts do not ultimately do much damage outside the ring.
• Dirty Old Man: Being in his 80s, he's obvious the elder sibling, he also admitted he admitted he wanted to take advantage of Genkai when he was human, then insults her age in a more disrespectful manner than his brother. Younger was not amused.

• Fate Worse Than Death: He is trapped in a hallucinogenic plant that feeds on his life force indefinitely.
• Faux Affably Evil: 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.
• For the Evulz: He is really guilty of this, there was really no point of telling Kuwabara of Genkai's death and then graphically showing how she died through a "puppet show" other than being a a nasty little waste of space. it backfired epically
• From a Single Cell: He can regenerate from anything which is ultimately used against him.

• Impaled with Extreme Prejudice (what he does with his fingers)
• Jerk Ass: While his brother is a Noble Demon, he is so repulsive to every one that Kurama decides that putting him through a "living hell" plant for all eternity because death wouldn't cure of it.
• Jerk with a Heart of Jerk: During the Dark Tournament, he promised to spare the lives of two of his opponents, if they begged for their lives. They begged and he killed them anyway.

• Not-So-Harmless Villain: He had been long considered only "Toguro's shoulder monkey". Then he fought three of the Ki-Rangers team and crippled two and killed the third in a single move, creeping out the whole stadium with how he did it.
• People Puppet: He does this with his hands to show how Genkai died this pointless action in an attempt to destroy him mentally in addition to Kuwabara's shame of not knowing the truth led to his defeat
• Recurring Boss: While he isn't the Big Bad by any stretch, he might as well be - he's the most recurring enemy that Yusuke and his crew go up against. During their raid on Tarukane's mansion, he's leader of the Apparition Gang. During the Dark Tournament, he's one of the co-founders of Team Toguro. And during Chapter Black, he's a key member of the Sensui Seven.
• Sadist: Fully admits he gets off on the pain of others, he's much more open about it than Karasu.

• Stupid Evil: Played with. He's not exactly an idiot, but he tends to do incredibly pointless acts of evil despite having a clear advantage, till he does those said acts.
• Villain Ball: While not unnecessary stupid, the Elder tends to be very boastful of how sick he is and his tendency to be sadistic at every single moment is what tests everyone's temper even his younger brother, and which causes the ones he fights who had previously had a major disadvantage to go Unstoppable Rage on him and causes anyone who listens to his twisted drivel to lose any respect they had for him.
• Why Won't You Die?: Most common reaction towards his constant returns. Ironically says the same thing while under Kurama's hallucination.
• Would You Like to Hear How They Died?: Told how Genkai died to Kuwabara in an extremely graphic way. It backfires, and then raves about he caused Makihara to commit suicide in order to escape the pain of being devoured from the inside out. It epically backfires.
• You Are Already Dead: Kurama ultimately disposes of him by trapping him in a hallucinating plant for all eternity.

Sakyo N.

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.

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, for no other reason than to just see what happens. For a short while, he was Shizuru's romantic interest.

---

• Affably Evil: He's very polite and gentlemanly for a villain, especially towards Shizuru.
• Ax-Crazy: In his younger days, he enjoyed dissecting animals, and eventually humans. Present-time, however, he seems to have moved on from that particular sin.
• Big Bad: Of the Dark Tournament saga.
• Bigger Bad: Eventually becomes this after his self-inflicted demise, as his past actions have deep repercussions during Chapter Black, 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.
• Bishōnen: Reasonably attractive, even with the scar on his right eye.
• Bored With Insanity: Sort of—he eventually became bored with personal killing and torturing, and found gambling to be his truest pleasure.
• Card-Carrying Villain: Freely admits that he doesn't have a Freudian Excuse and is just rotten to the core for no reason.

• Corrupt Corporate Executive: Gambling on the torture and destruction of demons, and organizing a tournament for this reason, just to earn more money...

• Dub Text: 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.
• Even Evil Has Standards: It is poor taste for a gambler to cheat, and Sakyo does NOT tolerate poor taste gracefully.

• Fiction 500: 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... 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").
• For the Evulz: Wants a portal to the Makai to be opened...just so life will be more interesting as the world goes to hell. he gets his wish in the end, but it's not the way he wanted to.
• The Gambling Addict: Self-admitted, and to the point of gambling his own life at some point. And keeping his word when he loses.

• I Gave My Word: 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.
• Kick the Son of a Bitch: While he does have some genuinely evil moments, at least two of them have him offing some very Corrupt Corporate Executives... to further his own ends, of course.
• Long-Haired Pretty Boy: Has more of a mullet, leads to the same Face of an Angel, Mind of a Demon effect as Karasu

• The Man Behind the Man: He's in charge of Team Toguro, and is thus the true villain of the Dark Tournament saga.
• Nightmare Fetishist: He claims to have been fascinated by death and suffering since childhood.
• Non-Action Big Bad: He serves as the fifth member of Team Toguro, but acknowledges that he can't fight. 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 wins in that case would win the round and the tournament.
• Non-Action Guy: In a Double Subversion, he reveals himself as the fifth member of Team Toguro... before wagering his life on Toguro so he doesn't have to fight.
• Pet the Dog: His interactions with Shizuru (Anime only).
• Posthumous Character: Even after his death, he still has an influence on the Chapter Black saga via Sensui's backstory. 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.

• The Sociopath: 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.
• Taking You with Me: 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.
• Visionary Villain: Averted in the manga, but his portrayal in the anime invokes this. See For the Evulz above for details.

Karasu

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.

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. He takes quite a liking to Kurama.

---

• Ax-Crazy: Not as much as Elder Toguro, but he is dangerously obsessed with killing Kurama. He's far more dissonant about his insanity than Elder Toguro's blatant madness.
• Badass: Even if he is nuts, the guy is just plain awesome as far as his powers are concerned.
• Badass Longcoat: Rocks the trench coat and Cool Mask look.
• Bishōnen: A definite one for the villains's side.
• Cool Mask: A gray one with tiny spectacles it acts as a restraint for his powers.
• Depraved Homosexual: In love with Kurama and shows this with his desire to kill him.
• Dissonant Serenity: 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.
• Evil Genius: Take a good look, ladies and gentlemen; this is one of the few men who can outsmart Kurama.
• Lightning Bruiser: Is extremely fast and swift. He can plant sticks of dynamite on you before you even notice he's moved.
• Mad Bomber: His fighting style, utilized by conjuring hand-grenades, dynamite and mines.
• Not So Stoic: When his mask comes off.
• Power Limiter: He becomes much more powerful (and psychotic) once his mask comes off. Also, his hair turns blond when said limiter comes off.
• Psycho for Hire: Is one like Elder Toguro, but has Dissonant Serenity to back it up.
• Pyrrhic Victory Despite being killed, he wins his match via a technicality.
• Sadist: He does like seeing his prey in agony.
• Shout-Out: Once he enters his Super Mode, Koto makes one to Dragon Ball Z. Seeing how his voice actors are Teen Gohan in the U.S. and Vegeta in Japan, the directors were in on the joke...

• The Stoic: Normally this, even in his Yandere moments when his mask is on.
• 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.

Bui

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.

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.

---

• Anti-Villain: Similar to Younger Toguro in a sense . However, as firmly aligned as he is to the team, he's never shown partaking in excessive brutality like his fellow members, instead preferring to give his opponents a quick and merciful death.
• Aroused by Their Voice: Lampshaded in-story.
• An Axe to Grind: His main weapon, until he uses his battle aura.
• 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.
• Battle Aura: When he removes his armor.
• The Brute: He's so freakishly strong that he's able to deflect and toss Hiei's darkness dragon up in the sky.
• Death Seeker: Wants to die after Hiei defeats him, believing he cannot get any stronger. Not that Hiei obliges to do so.
• Evil Sounds Deep: He's not evil per say, but he does have a deep, sexy voice - lampshaded in-story.
• Genius Bruiser: Much more intelligent than he appears.
• Hidden Depths: 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.
• Lightning Bruiser: Significantly faster than his opponent in the semifinals expected.
• Power Limiter: His armor acts a power restraint that keeps his battle aura under control.
• The Quiet One: Never speaks until his fight with Hiei.
• Shed Armor, Gain Speed: Not surprising since his armor is a Power Limiter. Even with it on he's faster than he seems, but once he removes it he's capable of flight and even faster.
• Villain by Default: Only really consider a bad guy because he's on Toguro's team.
• What Happened to the Mouse?: Never seen again after Hiei spares him. The last time we see him in the manga, he's watching Yusuke's fight with Toguro.

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 Humans Are Bastards 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.

---

• Ax-Crazy: Varies from very obvious to subtle Dissonant Serenity.
• Badass Crew: Their mental games and nasty moral dilemmas easily make them Team Urameshi's toughest opponents.
• Code Name: They all operate using code designations instead of their real names. (Black Angel, Gatekeeper, Sniper, Seaman, Gamemaster, Gourmet and Doctor). Save for Elder Toguro.
• Driven to Suicide: Don't seem to mind that their plan might mean that they'll be killed by demons as well; though, Gamemaster seems to not realize this
• Seven Deadly Sins: Each represents a Sin respectively, Seaman (Envy), Sniper (Pride), Gamemaster (Sloth), Doctor (Wrath), Gourmet (Gluttony), Gatekeeper (Lust) and Elder Toguro (Greed); with Black Angel being without sin unless you count the flawed six other personalities he has
• You Have Out Lived Your Usefulness: They generally have this attitude towards one another when they're cornered.

Black Angel - Shinobu Sensui

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.

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, 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.

---

• Affably Evil: His real personality "Shinobu" is a strange case. He is shown to be well-mannered and polite, even wanting to shake Yusuke's hand when they first meet. Which doesn't stop him from breaking his arm and going Ax-Crazy after. And while he does show remorse after he kills Yusuke, and is very understanding of Yusuke's friends wanting to seek vengeance, he still desires to kill all humans.

• Anti-Villain: Both a type I and II. He sees his actions as atoning for his past actions. Though the apocalypse he seeks to bring about upon Humanity is only a secondary goal in which he seeks to be killed by a demon.
• Ax-Crazy: His "Kazuya" personality, with a heaping side of Gorn and Combat Sadomasochist! Though he is still insane for having seven personalities, including a psychotic killer. It's just that Kazuya is the most blatantly insane.
• Badass: The strongest full-blooded human in the series until he dies and passes that title to Kuwabara.
• Badass Gay: Yeah, he's a villain, and he has a lot of issues, but he's also a martial-arts prodigy born with a very strong spiritual sense and the World's Strongest Man until his death.
• Bad Boss: He doesn't give a damn about whether his subordinates live or die, only whether they fulfill their tasks.
• Big Bad: Of the Chapter Black saga.
• Black and White Insanity: The fact that Humans Are Flawed and thus can't be neatly labeled in terms of absolute good and evil is what broke him.
• Blood Bath Villain Origin: To be fair, the Black Black Club deserved it.
• Blue Oni Red Oni: Blue Oni to Yusuke's Red Oni.
• Boomerang Bigot: A human leading a crusade of genocide on the entire human race.
• The Chessmaster: Yusuke and his friends have become so adept at combating evil as warriors that Sensui's cerebral, calculating and ruthlessly intelligent evil renders them completely helpless.
• Covered with Scars: They're self-inflicted.
• Curb-Stomp Battle: Most fights with him are this, especially the three-on-one. When fighting seriously he is among the most powerful villains in the series, which is saying something since the rest of them are demons. It takes Raizen, who has been stated to unequivocally be the most powerful character in the entire series according to the author, intervening to finally beat the guy. The real irony? He was already dying to begin with.
• Dangerously Genre Savvy:
  • More than just his prior Detective experience, Sensui has a fond love of movies and video games—a love he 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 Yusuke's death would be immaculately on-sync with the end-credit song. It works, too.
  • Also, when Gourmet/ Elder Toguro proved to be useless as he needed Kuwabara's power to activate with the latter being unable to use it, he invokes Roaring Rampage of Revenge in Kuwabara, knowing that Kuwabara'd do anything to avenge his friend and even cut open Hell itself to do it.
• Dark Messiah: Interesting in that he was one Face-Heel Turn away from being an actual Messiah.
• Death Equals Redemption: 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.
• Death Seeker: Combined with Suicide by Cop.
• Death of a Thousand Cuts: What the Splinter Roushuyuken does

• Does This Remind You of Anything?: 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 Coming-Out Story. Especially in the dub.
• Driven to Villainy: Thanks to that damn Black Black Club... though it's also kind of his own fault as well. Sensui's 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.
• Enlightened Antagonist: Sensui utilizes Sacred Energy/Holy Chi, a form of energy so great that it requires not only years of discipline and training but an understanding of the world to operate on a higher plane and transcend the physical realm. Despite this achievement, he planned to initiate a complete genocide of all humanity and is not above slaughtering whoever gets in his way.

• Evil Genius: A rare Darker and Edgier version that's also a Big Bad in the series.
• Evil Plan: Open a portal to Demon World and flood the Earth with demons because he hates humans. 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.
• Extremity Extremist / Energy Ball: The Roushuyuken is a ball of energy that Sensui kicks at his opponent.

• Facial Markings: His bindi.
• Fallen Hero: Used to be Spirit World's finest before everything went to hell.
• Genius Bruiser: 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 S-Class shown.
• Golden Super Mode The main Shinobu personality's Sei-Kou-Ki/Sacred Energy.
• Go Mad from the Revelation: He definitely saw some things he shouldn't have, that broke his brain... However, the madness was aided and abetted by the Chapter Black tape.
• Good Hair, Evil Hair: It's slicked back when he appears as a Big Bad, but in flashbacks, when he's a Spirit Detective, it's more of a bowl cut.
• He Who Fights Monsters: He believed in this so strongly that it ultimately broke him when he found out the possibility that humans are not the saints that they're made out to be.
• Humans Are the Real Monsters: His pet hangup.
• Kill All Humans: His stated goal and mission though it turns out to be a secondary aim to his true goal of a Karmic Death in Demon World.
• Knight of Cerebus: 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.
• Light 'em Up (His main personality's Sei-kou-ki/Sacred Energy. Also an example of Light Is Not Good.)
• Macho Masochism: Double Subverted. When he takes off his shirt after falling into the lake, the first thing the heroes notice about him are his 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, he refutes that he got all those scars training himself. Yusuke lampshades it in the dub:

  Yusuke: Awww, jeez, a masochist!

• Manipulative Bastard: His split personality, Minoru persona.
• Misaimed Fandom: In-universe example. Sensui fervently accepts the Chapter Black tape as the undisputed truth in its depiction of Humanity. Koenma corrects him by stating that Chapter Black is supposed to be watched along with Chapter White to get a balanced look on humanity's potential for great good and great evil. Thus Sensui is operating based on a misleading half-truth at best.
• Person of Mass Destruction: Though 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 the weakest one.
• Psychopathic Manchild: Type B and C. Though he does act like an intelligent and sophisticated adult, he still has the immature mindset of a child who can't accept the complexities of life.
• Pure Is Not Good: If Sensui wasn't so pure as a good guy, he couldn't have become so tainted as a villain. His main "Shinobu" personality is still pure and innocent after all these years. Sort of.
• Purple Is Powerful / Supernatural Is Purple: His bindi and Ki Attacks.

• Screw the Rules, I Have Supernatural Powers!: Part of his attitude/egotism after becoming a villain, in addition to hating humans.
• Serial Escalation: He can manipulate an energy ball that he uses in various, deadly ways, has seven personalities, each with a deadlier power, which is good for a Climax Boss, but reaches ridiculous levels of power with Sacred Energy, which can level the planet with its mere presence and shape itself into various kinds of armor.
• Seven Deadly Sins: Whereas 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.
• Significant Birth Date: 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 Number of the Beast with a seven left over.
• A Sinister Clue: Yep, he's left-handed.
• Soap Opera Disease: 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.
• Split Personality: Including the original, seven in total after losing it.
• Start of Darkness: Exposure to the depravity of humanity and then the Black Chapter tape.
• Straight Gay: By Word of God.
• Sympathy for the Devil: His world view was shattered and he spent his whole life trying to understand the creatures he hunted and the resulting guilt of those actions led him to Suicide by Cop.
• TV Genius: Sensui is extremely smart, but he seems to have no clue how to relate to people beyond using and/or killing them. Not Good with People is, in his case, an understatement.
• The Unfettered: Even when he was a good guy, he used the absolute extremes to deal with demons.
• Victorious Loser / Doomed Moral Victor: 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.
• Yaoi Guys / Official Couple / Mind Game Ship / Birds of a Feather / Unholy Matrimony: Him and Itsuki.
• Young Conqueror: Was born with very high spiritual awareness as well as being a martial-arts prodigy, in contrast to Yusuke's Idiot Hero.

Gatekeeper - Itsuki

Four times zero power is still zero power.

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.

---

• Action Survivor: He does have supernatural powers, but they're not very useful in battle. However, he gets by by being a ginormous Manipulative Bastard...
• Ax-Crazy: A Dissonant Serenity 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.
• Bishōnen / Long-Haired Pretty Boy: As seen above. The guy is very, very pretty, even if not to Dude Looks Like a Lady degrees.
• Corrupt the Cutie: 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 Mind Game Ship.
• Dissonant Serenity: 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 Mad Love). Also, his Ura-otoko is full of dead bodies, airplane wreckage, etc.
• The Dragon: Sensui's left hand.
• Evil Genius: 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.
• Eyes Do Not Belong There: His shadow hands are covered in unblinking Purple Eyes.
• Fauxlosophic Narration: About half of his speaking lines are this.

• Karma Houdini: He takes Sensui's corpse with him into pseudo-space and is never seen again. Being that he is no longer a threat to Spirit World and is in area they cannot pursue lest they wish to be stranded with him, his file his permanently closed. Additional note should be made that of the five surviving members of the Sensui Seven, Itsuki was the only one (or two if you include Elder Toguro) who has made no attempt to atone for his actions.
• Mad Love: To Sensui. Both are incredibly unhinged and Itsuki is very aware of it, yet he's still incredibly loyal and in love with his leader.
• Manipulative Bastard: Of the passive-aggressive variety.
• Moral Myopia: 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, despite what he and Sensui did.
• Multi-Armed and Dangerous: His shadow hands.
• Non-Action Guy: But he is surprisingly Badass for one. And woe betide anyone who makes him angry...
• The Philosopher: Somewhat of a subversion, as he's bloody crazy.
• Psycho Supporter:
  • Itsuki from the anime loves 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 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 "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.
• Seven Deadly Sins: As one of the Sensui Seven, he represents Lust.
• Single Specimen Species: The only yaminade left.
• Single-Target Sexuality: Taken to a very obsessive degree - he loves Sensui. A LOT.
• Softspoken Sadist: His smooth, mellow voice tends to hide his inner crazy.
• Stalker with a Crush: In the Funimation dub at least, Itsuki was once this for Sensui.
• Subordinate Excuse and Undying Loyalty: Holds both of these towards his ex-partner, now leader and lover: Shinobu Sensui.
• Villain Teleportation: A variant with his power over dimensions and the Ura-otoko.
• Yaoi Guys / Official Couple / Mind Game Ship / Birds of a Feather / Unholy Matrimony: Him and Sensui.
• You Gotta Have Blue Hair: Well, turquoise, but still...

Sniper - Kaname Hagiri

I've got no quarrel with you, stranger.

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.

---

• Always Accurate Attack: 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. 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 Younger Toguro and Sensui himself, he comes closest to actually killing Yusuke. Genkai was promptly terrified when she realized how he shot Murota.

• Biker Babe: He seems to fit this trope better than Badass Biker, especially knowing his boss...
• Cold Sniper: 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, 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 Cold Sniper quite well - out of all the Sensui Seven, he's the least emotional and crazy, and fights purely methodically. (Though he can also be Not So Stoic, and after Itsuki he is the most unfalteringly loyal to their leader Sensui.)
• Combat Pragmatist: He's not above toying with his victims, but he never lets it go on for too long either.
• Curb-Stomp Battle: 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 Hiei's big damn heroic moment, Yusuke would've been dead a second time.
• The Dragon: Sensui's right hand.
• Eerie Pale-Skinned Brunette: He's a pale teenager with jet black hair, a poker face, and very creepy intentions.

• Even Evil Has Loved Ones: About the only human he truly cares about is his sister - she even somewhat serves as his Morality Pet, not that it deters him from his goals.
• For the Evulz: 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.
• The Gunslinger: Always carries a pistol with him, just in case.
• Impaled with Extreme Prejudice: By Hiei, non-fatally.
• Improbable Aiming Skills: When someone is in his territory, and he can mark them to allow objects to home in on them.
• Improbable Weapon User: Let's see, he uses dice, marbles and shot a guy on the head bloodtastically with a pencil eraser.
• Karma Houdini: Aside of simply disappearing at some point, he doesn't really get much punishment for what he did as a Sensui Seven member.
• Nothing Personal: Says this to Hiei right before he was about to shoot him.
• Psycho Supporter: He might be the second most crazily devoted member of the Sensui Seven, right after Mr. Mad Love aka Itsuki.
• Seven Deadly Sins: As one of the Sensui Seven, he represents Pride.
• Shout-Out: Honestly, who doesn't think he looks a bit like Kaneda?
• Squishy Wizard: Practically unstoppable at a distance. If that distance is closed however, the threat level plummets.
• There Is No Kill Like Overkill: Lampshaded by both Yusuke and Kaname himself when he locks a fuel tanker onto Yusuke's bull's eyes.
• Undying Loyalty: Is the most loyal to Sensui, after Itsuki.
• Weak, but Skilled: There's a reason he's called 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.
• Why Don't You Just Shoot Him?: After playing around with Yusuke as target practice, he finally opts to just gun him down with a pistol. If Hiei didn't arrive in the nick of time, that definitely would've been the end of him.

Doctor - Minoru Kamiya

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.

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.

---

• Ax-Crazy: 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.
• Brainwashed and Crazy: 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.
• Despair Event Horizon: What he saw on Chapter Black, made him nihilistic enough to wish for the death of all humanity
• Facial Horror: Courtesy of Yana. He got better looking in the epilogue.
• Four Eyes, Zero Soul: He was once of the most sadistic members of Team Sensui, at least before he escapes from prison, changes his face, and founds a clinic to help others.
• Good Powers, Bad People: Has Healing Hands, but uses them to kill others.
• Healing Factor: He can numb the pain receptors and use his ability to reattach his limbs.
• Healing Hands: He can reattach limbs with his powers, making him very hard to put down however, he decides to use those powers for others later one.
• Heel Realization: After a short while after the Sensui incident, he realizes that he was very wrong and decides to help others.
• Karma Houdini: 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 No-Holds-Barred Beatdown from Yusuke.
• Mad Doctor: This guy is freaking crazy until he realizes that he needs to make amends for his actions.
• Morally Ambiguous Doctorate / Deadly Doctor: He can used his medical training to infect others with diseases or repair himself.
• My God, What Have I Done?: Realized how far off he went and decides to use his skills for the betterment of others.
• Nietzsche Wannabe: Doesn't care if humanity is eaten by demons, in fact he welcomed it.
• Psycho Supporter: Possibly the biggest one, as he fully intends to be killed by demons when they show up.
• Seven Deadly Sins: As one of the Sensui Seven, he represents Wrath for his extremely violent methods.
• The Sociopath: He is paranoid, a liar and had no guilt about hurting others.
• Starting A New Life: After the events of YuYu Hakusho, 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 Heel Realization.

Seaman - Kiyoshi Mitarai

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

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 - [[You Have Outlived Your Usefulness simultaneously making him Sniper's next target]. He has the power to mix his blood with water to create powerful golems.

---

• Ax-Crazy: Pre-Heel-Face Turn, he was pretty eager to use his powers to kill others. Even in his Motive Rant, he was making horrible Nightmare Faces as he explained his reasons.

• Bloody Murder: Seaman's power is to create monsters by mixing his blood with water. Which he strangely doesn't use after his Heel-Face Turn, although it can be justified because it needs a large source of water to strengthen it.
• Break the Cutie: The massive bullying that he went through and what he witnessed in the Chapter Black video simply... broke him.
• Even Evil Has Standards: Was disgusted by Doctor and his intentions, even when they were both part of the Sensui Seven.
• Freudian Excuse: Was savagely bullied in his former school, then Sensui subjects him to watch the Chapter Black.
• Heel-Face Turn: As said above, Kuwabara's kindness and the help of the Urameshi Team help him leave the Sensui Seven.
• Making a Splash: Has the ability to animate water to attack people with by mixing his blood in it.

• Seven Deadly Sins: As one of the Sensui Seven, he represents Envy.
• Stock Shoujo Bullying Tactics: We see him as a victim of both the "ignoring" and the "physical violence" tactics.
• Villainous BSOD: 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...
• You Have Outlived Your Usefulness: Neither Sensui or Sniper were really bothered with the idea of killing him off immediately the moment Kuwabara took him in. That too was a part of Sensui's plan to lure out Kuwabara.

Gamemaster - Tsukihito Amanuma

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

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.

---

• Achilles' Heel: Amanuma is not immune to the laws of his own world. He has to follow the rules set forth by the game that he manipulates. This comes back to bite him royally in the ass when he emulates Goblin City and assumes the role of a character that is destined to die when the challenger wins.
• Affably Evil: Has a rather smart mouth, but is easily the friendliest of the seven.
• Back from the Dead: Fortunately, Koenma pulls a few strings.
• Creepy Child: Come on, this is a kid under 12 and he's working for the Arc Villain.
• Children Are Innocent: 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) until he's forced to face the consequences of his actions. He doesn't even have any ill will towards Team Urameshi, and 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!
• Curtains Match the Window: He has brown hair to match his brown eyes in the manga
• Hannibal Lecture: Tries one on Mitarai during their match to distract him, but Mitarai is able to persist and win.
• I Know Mortal Kombat: In the most literal way imaginable.
• Killed Off for Real: An enraged Kurama is forced into a situation where he has to kill the child.
• Locked Out of the Loop: 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
• Loners Are Freaks: One of the factors that turned into a Misanthropic kid willing to join Sensui's crusade to destroy Humanity. Subverted at the end following the failed apocalypse when he manages to make friends.

• The Reveal: 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.
• Reality Warper: His powers allow him to make video games into reality.
• Seven Deadly Sins: As one of the Sensui Seven, he represents Sloth.
• Unskilled, but Strong: His powers, even if restricted to video games is undoubtedly very great; but he hasn't practiced much with it, so he can't manipulate it to cheat or to abort a game in progress. All According to Sensui's plan.
• Unwitting Pawn: Sensui completely played on the poor kid's weaknesses and desires to make him his pawn. Amanuma didn't notice until Kurama told him that he would die if he lost his own game.
• Villainous Breakdown: Kurama 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.
• Your Size May Vary: Just after he is first shown, he drives the truck when the Sensui Seven kidnaps Kuwabara. An elementary school student drove a truck.

Gourmet - Sadao Makihara

Touching, Seaman. You want to save Kuwabara so very badly because he saved you, but at the same time you're terrified of letting Sensui find out how much your new buddy means to you, aren't you?

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.

---

• Assimilation Backfire: Gourmet eats Elder Toguro to get his powers, Elder Toguro ends up taking over his body later.
• Breaking Speech: Strangely fond of these, especially being Dumb Muscle and all... Subverted, of course as it's really Toguro talking.
• Cannibalism Superpower: When he eats other demons or psychics, he gains their powers.
• Dead Person Impersonation: A very dark variant, he ate Elder Toguro, only for the latter to slowly devour him and the realization led him to suicide.
• Demonic Possession: When he tries to eat Elder Toguro, the parasitic demon instead ends up taking over his mind and body.
• Driven to Suicide: In order to escape the terror being Eaten Alive from the inside out.
• Dumb Muscle: Lampshaded by both Sensui and Toguro.
• Eaten Alive: Does this to Murota and Elder Toguro, in a sick twist of irony, the latter slowly does this to Makihara.
• Eyes Always Shut: Except for one instance when he tells Kurama about how much guilt he had for killing Game Master.
• Forgotten Fallen Foe: Notably the only one of Sensui's group not to be given a mention/come back to life in the arc's epilogue, though given how he'd been completely consumed by Elder Toguro beforehand, it is understandable.
• Hoist by His Own Petard: His power backfires when he tries to devour a parasitic demon like Toguro.
• I'm a Humanitarian: Ate Murota to gain his Telepathy power, did the same to Elder Toguro, but it backfired and led to his suicide.
• Mega Manning: He's able to gain the abilities of who he eats.
• Mind Rape: After eating Murota, he does this to Kurama resulting in an angered reaction
• Off with His Head!: Kurama cuts the top part of his head off, subverted as Elder Toguro bursts out to reveal it was really him the whole time.
• Seven Deadly Sins: As one of the Sensui Seven, he fittingly represents Gluttony. Also a twofer example as Elder Toguro is the embodiment of Greed.
• Swallowed Whole: How he eats people.
• Villainous Glutton: His power is eating people and is very much a glutton, plus he is a part of a group that wants to start the apocalypse and he tried to Mind Rape Kurama Though the latter part was due to be being Elder Toguro being in control
• Walking Spoiler: He's actually Elder Toguro using Gourment's body after the latter ate him.
• We Hardly Knew Ye: We never knew what Makihara was like before Elder Toguro took over, by the time he showed up; it's already Elder Toguro masquerading as him.

Elder Toguro

See Team Toguro folder.

Koashura

---

• Big Bad: Of Yu Yu Hakusho: The Golden Seal. Later is shown to be a Big Bad Wannabe.
• Love Makes You Evil: He is angry at Koenma for taking the affection of a girl when they were younger.
• Punny Name: Koashura's name means "Little Asura" much like how Koenma's name means "Little Enma".

Garuga /Yasha

Koashura's right hand man in carrying out his plot against Koenma. He is actually a wanted criminal named Yasha who wants the Golden seal for his own purposes.

---

• Attack Reflector: Located on his chest which can reflect energy attacks.
• Bishonen Line: While his transformed state, Yasha's true form to be more exact, is still monstrous in appearance, but is far less bulky and allows him to be swifter in battle.
• The Dragon: To Koashura Later revealed to be The Starscream.
• Dumb Muscle: Garuga demonstrates that he is a subversion. He reveals that it was merely an act to make Koashura think he was in charge, but was simply manipulating him for his own means.
• Hoist by His Own Petard: Yusuke defeats him in his true form by sealing the reflector on his chest using the magma found in the Magma Valley.

Yakumo

The main Antagonist of Yu Yu Hakusho: Meikai Shito Hen - Hono no Kizuna.

---

• All-Encompassing Mantle: He wears a dark cloak with a turnover collar.
• Authority Equals Asskicking: He was the ruler of the Netherworld, which was destroyed and assimilated into Spirit world, and demonstrates that he is not to be taken lightly. He is estimated to be at A Class in power and goes to S Class upon regaining the Netherworld Power Sphere.
• Bad Boss: Downplayed. Shortly after seeing Hiei incinerated Raiko with multiple Dragons of the Darkness Flame, he simply turns away remarks along the lines of "sucks to be you".
• Badass: Yakumo was notably the only antagonist to fight against all four members of Team Urameshi at the same time.
• Big Bad: Of Yu Yu Hakusho: Meikai Shito Hen - Hono no Kizuna / Yu Yu Hakusho: Bonds of Fire / Poltergeist Report
• Canon Foreigner: He and the other Makai Gods were created for this film, though the concept for them is derived from some latent ideas from the Manga. Canonically, the Demon plane is simply another part of the Spirit World of which King Enma and his forces have gradually subjugated. The movie portrayed it as part of a separate pre-existing realm that was assimilated after a war between Enma and Yakumo.
• Catch Phrase: "Know Your Rightful Place!" which he tends to particularly addresses to Humans.
• Dark-Skinned Blond: Though his hair is white.
• Evil Versus Evil: Is this in the background of the movie with King Enma by default of revelations in the last chapters of the manga.
• Filler Villain: Though he is the co-Trope Namer (along with Lanipator 's Yu Yu Hakusho Abridged), ironically he actually averts this as he debuted in a Non-Serial Movie, not any episodes of the television series.
• Fingerless Gloves: The type of gloves he wears.
• Foil: To Sensui. Whereas Sensui was a Fallen Hero Messianic Archetype who became an anti-villainous Dark Messiah with an inflexibly strict since of Justice, Yakumo, while he may agree with Sensui's assessment about Humanity (read Humans are Bastards below), is an unabashedly wicked Satan-like God of Evil who could not careless about Humanity perhaps except as livestock.
• Humans Are Bastards: Yakumo harnessed the power of the souls of evil Human beings who were banished to the void to free himself and his fellow Makai gods.
• Meaningful Name: The kanji that make up Yakumo's name can mean "eight clouds" or "august cloud" which is fitting given that he is the former King of the Netherworld.
• Mind Manipulation: Yakumo is able to exert his will over any demons under the influence of the Netherworld, designated by the cross-shaped mark on their foreheads. With his being the King of the Netherworld, and his influence wiping away the last traces of free will, the affected demons essentially become slaves to his will.
• Our Gods Are Greater: And he takes plenty of opportunities to snidely remind his enemies to respect that he is a god.
• Purple Eyes: He possesses irises of this color signifying his supernatural origins and, in reference to color association in Japanese culture, that he is evil.
• Purple Is Powerful: His aura manifests as a purple color.
• Reality Warper: One of the powers he has when in possession of the Netherworld Power Sphere.
• Satanic Archetype: He has shades of this. He had waged a war against King Enma eons earlier, ruled The Netherworld, and is also quite ambitious in his goal to displace Enma as the ruler of all existence.
• Sealed Evil in a Can: Following his defeat at the hands of King Enma, he and the rest of the Makai gods were banished to the void.^note  The Central Park Media due calls this as "Deep outer space". However, he managed to convert the souls of Human beings damned to the void into Demon energy and broke out of his prison from the inside.
• Smug Snake: And he has the power to back it up.
• Telekinesis: One of Yakumo's abilities.
• Visionary Villain: In addition to seeking to conquer Spirit world, his plan is to recreate the Netherworld in the Human World via an Assimilation Plot with the use of the Power Sphere of the Netherworld.
• White Hair Dark Heart: As can be seen here.

Other Makai Gods

Yakumo's subordinates.

---

• Bald of Evil: Raiko As can be seen here.
• Barbarian Longhair: Kaiki has his red hair in this style.
• Combat Pragmatist: Kaiki has no inhibitions to taking an opening when he sees one. This ends up giving him away when disguised as Kuronue as the latter refused to ever attack someone from behind.
• The Corrupter: One of the abilities of Raiko's Jagan Eye gave him the ability to put others under his will by "bringing out their wickedness" which he does on Hiei However, the Dragons of the Darkness Flame could not be effected by the trance when they were released upon Raiko's attempt to control Hiei and shortly after destroyed the Makai deity in a giant ball of Hellfire.
• The Dragon: Raiko serves as this for Yakumo.
• Dude Looks Like a Lady: Majari. The Central Park Media dub deliberately gave him a very Camp Gay vibe to him in an effort to avoid Viewer Gender Confusion.
• Extra Eyes: Raiko possess a Third Eye. His Jagan Eye is similar, albeit more powerful than Hiei's, though unlike him Raiko has absolutely no moral restraint in how he uses it.
• Knight Templar: Majari proclaims in his fight against Kuwabara his devotion to Yakumo's plan. Raiko is also this to a lesser extent.
• Laser Blade: Raiko has the ability to create a BFS. Majari gains this ability via copying Kuwabara's Spirit Sword technique.
• Manipulative Bastard: Kaiki plays on Kurama's grief for his lost comrade to take advantage of him.
• Playing with Fire: One of Raiko's abilities.
• Power Copying: Majari's specialty.
• Shapeshifter Guilt Trip: Kaiki's method of operation is to use this on opponents so as to get them to refuse to fight back.
• Spell My Name with an "S": Some translations spell Raiko's name as "Raigo".
• Squishy Wizard: Majari, once Kuwabara tricked him into blasting out all his energy, was left vulnerable without his powers.
• Telepathy: One of Kaiki's abilities which he uses in conjunction with illusionary shape shifting.
• Undying Loyalty: Raiko has this for Yakumo and doesn't take kindly to slights against him.

Kuronue

A thief and former associate from Kurama's past who is featured in the movie Poltergeist Report.

---

• Back from the Dead: Subverted. The real Kuronue is dead, the one Kurama confronts is an imposter.
• Bat out of Hell: Kuronue is a Bat Demon.
• Canon Foreigner: He was created for this film.
• Enemy Mine: He joined with Yakumo in order to carry out his vendetta against Kurama. See Revenge for details.
• Expy: Let's see, he's villain that is a former accomplice of Kurama. This may sound like Yomi, but actually averted and simply coincidental as at the time Bonds of Fire/Poltergeist Report was released (April 9, 1994) the Manga and its Anime adaptation where still in the middle of the Chapter Black arc. Though Kuronue could possibly be an inversion in relation to Yomi if the latter was in part inspired by former.
• OOC Is Serious Business: He tosses away his pendant just as he is about to stab Kurama in the back. Kurama is able to deduce that the Kuronue he is fighting is an imposter.
• Posthumous Character: While escaping with their loot, Kuronue was killed trying to go back for his pendant.
• Revenge: Against Kurama for failing to come to his rescue in the past. Subverted as the person Kurama is fighting against is merely an illusion.
• Winged Humanoid: He fittingly has a set of Bat-like wings.

King Enma

King of the Spirit World and father of Prince Koenma.

---

• Adaptational Heroism: In the anime due to omitting revelations that came about in the last chapters of the manga.
• Authority Equals Asskicking: He has power that is estimated to be at middle or upper A Class.
• Balance Between Good and Evil: He has proclaimed that he values the balance of the Spirit, Human, and Demon worlds. It is subverted in that it has nothing to do with any sort of utilitarian goal but is for a self-serving purpose of giving him exclusive access to the Human world's souls.
• Beast Man: Many characters imagine him to look like this, but when he finally appears in person during the Chapter Black arc he is, aside from being a giant, no different in appearance to an average Human. You can compare the images his actual and imagined appearance here.
• Big Good: As the King of Spirit World and the source from which the office of Spirit Detective derives its authority, he would be this naturally. Except for the fact that he's a subversion as he's the Bigger Bad. In the manga King Enma is responsible for just about everything, in the name of keeping his public image as powerful as possible—after all, Team Urameshi work for him, so if they take out a criminal, he can take credit for it.
• The Corrupter: He committed crimes of brainwashing weak demons to make them attack humans and portray the Spirit World as the Human World's protectors.
• Corrupt Politician: What Koenma discovered about him near the end of the Manga and had him deposed.
• God Is Evil: An interesting non-Abrahamic, non-monotheistic, nor Crystal Dragon Jesus example. He released demons into the Human world in order to stir up trouble and thus add meaning to his existence. Though unlike most examples of this trope as Enma is only the Judge of the dead and not the Top God of the pantheon, he gets his comeuppance.
• The Gods Must Be Lazy: While he isn't shown for most of the time, he actually is an interesting subversion of this trope. He's the source of most of the problems that occurred.
• Hair-Trigger Temper: Koenma describes him as having a temper like this during the Artifacts of Darkness arc. He said that he would be willing to destroy an entire continent to retrieve them.
• Large and In Charge: He is literally gigantic.
• Noble Bigot with a Badge: In his case it would be more like "Noble Bigot with a Crown". Regardless, his actions resulted in proving that the "Noble" part is Blatant Lies.
• Villain with Good Publicity: He manipulated Demons to cause crimes in Human World for centuries. It was to justify maintaining Spirit World's exclusive access to the Human world and intervening under the claim of protecting Humanity, but in truth was seeking to control the Human world for his own personal gain.
• Walking Spoiler: Most of the details of his biography involve giving away a major plot twist.
• Well-Intentioned Extremist: Definitely a Subversion.

The Special Defense Forces (SDF)

The SDF is a military group operating under the command of King Enma.

---

• Adaptational Heroism: In the anime due to omitting revelations that came about in the last chapters of the manga.
• Armies Are Evil: Zigzagged. While Ōtake and the rest of the leadership of the SDF are clearly aware of Enma's machinations, the rest of the team seems to have no knowledge of this. Even then, some members (see sociopathic soldier below) are sadistic thugs who enjoy abusing civilians. However, when the Sei-Sei Shinto initiate a coup attempt, Shunjun (the SDF member with slicked back, light blue hair and wearing earrings), aided Team Urameshi in thwarting the Terrorists (of which included Ōtake and other former Spirit World military and government officials from Enma's rule prior to his impeachment and removal) from achieving their goal.
• Badass Mustache: Captain Ōtake sports one.
• Continuity Nod: Kurama was a demon fox before he was injured in a botched robbery and merged with a human fetus to recover his energy. When the Spirit World SDF arrive near the end of the Chapter Black arc, several of them mention that one of them (Shunjun) was the one who injured him.
• The Dragon: Captain Ōtake serves as this for King Enma.
• Elite Army: They are all at Class A ranking in power meaning few enemies aside from those at Class S ( such as Yusuke reborn as a Human-Demon hybrid) can stand against them.
• Expy: Of the Science Patrol from Ultraman. In the Manga, Yana highlights the SDF's resemblance to the group.
• Godzilla Threshold: The only time the SDF is ever present in the Human world is if any being with Class A power or higher is detected there. Otherwise, they serve in helping Spirit World's forces in expanding their territory across the Demon world.
• The Hunter: They are colloquially known as this by denizens of the Demon plane.
• Jerkass: The two unnamed ones were harsh and sadistic towards Koenma and Mitarai, even ignoring that the latter had a change of heart and aided them in the conflict against Sensui. Captain Ōtake also qualifies, but is downplayed as he is more polite when addressing Prince Koenma.
• Locked Out of the Loop: When Yusuke, Koenma, and Puu manage to blow past them, it is only at this point that Ōtake reveals that there is a ranking of power above that of A class which comes as a shock to the rest of the team.
• No Name Given: Of the Nine shown members of the SDF, only two have no known names.
• Sociopathic Soldier: The two unnamed ones who took sadistic glee in beating Mitarai and then begging for mercy once Yusuke came back as a Mazoku Demon.
• Teleporters and Transporters: One of the powers that its members have. They can seal unauthorized portals between dimension and also create portals when ordered to.
• To Be Lawful or Good: The SDF is strongly on the Lawful side in upholding King Enma's decree

Yomi

You can never know victory unless you understand defeat.

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 plans to take over both the demon and human planes in an act of unification, calling on Kurama to his side.

---

• Anti-Villain: Would have probably been this, if it wasn't revealed that he continually tortured and then ruthlessly killed the assassin who blinded him (since he was just a random mook for all we know). Granted, he still shows a few signs of the trope in the anime, unlike his somewhat colder manga counterpart.
• 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! The most impressive of all his feats? He manages to force 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. Magnificent Bastard, indeed.
• Beam Spam: Used against Yusuke.
• Blood Knight: Yusuke helps bring this out of him, and Yomi admits that for all his planning and status, he's always wanted to fight against Raizen.
• Character Development: 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 Manipulative Bastard 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. 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!
• The Chessmaster: This guy managed to checkmate Youko motherfucking Kurama.

• Disability Superpower: 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!
• Even Evil Has Loved Ones: The reason Yomi was able to win against Yusuke during their Cross Counter 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.
• Friendly Enemy: He has to scheme and manipulate (because of the demon realm being a Crapsack World), but still always places emphasis on civility and negotiations before violence and plotting. After his fight with Yusuke, he pulls a Heel-Face Turn and even seems to respect him as a friend and rival of sorts.
• Handicapped Badass: Was blinded by an assassin hundreds of years ago sent by his former partner, Yoko Kurama, as punishment for being a Leeroy Jenkins. 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 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.
• Heel-Face Turn: In the end, he comes to some agreement with the heroes and decides to spend more time with his son.
• I Have Your Wife: Uses this on Kurama to get his cooperation. Replace "wife" with "mother" and "stepbrother" and there we go.
• Jerkass Façade: To his son, to make him stronger and more self reliant.
• Leeroy Jenkins: 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.
• Manipulative Bastard: This is pretty much the only character who can outsmart Kurama. And does so flawlessly. And gets away with it.

• Pyrrhic Victory: He wins against Yusuke in their match, but gets defeated in the next round because he exhausted himself.
• Red Oni, Blue Oni: When he was younger, he was the Red Oni to Yoko Kurama's Blue Oni. However, he starting developing Blue Oni traits after he lost his eyesight.
• Truly Single Parent: Shura is both his son and his clone.
• Visionary Villain: Wants to unite all of Demon World and then launch an assault on the human world to take it over. What his plan is after that is unknown, thoughts it hinted that he wants to use the combined strength of both worlds to defeat Spirit World and end their meddling.
• Worthy Opponent: Views Yusuke as one after Yusuke finds a way past his Deflector Shields.
• Would Hurt a Child: 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

Hiei, you needn't search for death. Death will find us all soon enough.

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.

---

• Authority Equals Ass Kicking: S+ Class demon.

• Belligerent Sexual Tension: Lampshaded by Kurama himself. He made notice that Hiei and her were enjoying maybe a little too much fighting with each other during the tournament.
• Body Horror: Half of her body is horribly scarred and deformed from sexual abuse and self-inflicted acid burns, and one of her legs is prosthetic.
• Broken Bird: Her past was sincerely horrific, and it left her mentally and physically scarred. See Body Horror for the reason why.
• Dark Action Girl: Less evil than usual examples though.

• Expy: Of the Norse goddess Hel.
  • Togashi has also said that Kushana of Torumekia was also an inspiration for Mukuro^note Togashi, Yoshihiro (1994). Assault Interview: Ask the Author!. ヨシりんでポン![Yoshirin de Pon!] (in Japanese). pp. 10–1..
• Fan Disservice: The full sight of her torn half, scarred and deformed half.

• I Was Quite a Looker: From the half of her body that isn't deformed she appears to be drop-dead-gorgeous.

• Made a Slave: Back in the days, before Mukuro became one of the three kings. Doubled as Sex Slave.

• Orgasmic Combat: Again with Hiei during the tournament since none of them really wanted to kill the other.
• Rags to Royalty: Self-Made Man.

• Reasonable Authority Figure: Described by Raizen as a "traditionalist" who is content with maintaining the current relations with the human world (in sharp contrast to Yomi who wishes to conquer it).
• Samus is a Girl: When she unveils herself as a woman, everyone in Makai is blown away! Only Yomi seems unsurprised, but then again this is Yomi.

• Two-Faced: Mukuro's body had been completely stripped of flesh on one side with strong acid. Though Mukuro is different from most examples, being a not-so evil demon (given a choice between Yomi and Mukuro, Raizen told Yusuke to side with Mukuro) and being female. Besides, said scars were self-inflicted, as she figured that uglifying herself would be the only way to escape her abusive caretaker (who did abuse her sexually, too).
• Tiny Guy, Huge Girl: With Hiei. She is One Head Taller than him.
• World's Strongest Man: According to Yomi's data, she is the world's strongest demon, at least now that Raizen is starving. Got defeated by Enki, but at the time she couldn't give it all in such a peaceful contest.

Raizen

You should be careful what you call a fortunate opportunity. Your luck could run out.

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 his descendant Yusuke to the Demon Realm as he is on the brink of death from starvation and requires someone to take his throne.

---

• Attack! Attack! Attack!: Combined with Combat Pragmatist. If his fight with 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.
• Badass 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.
• Big Damn Heroes: During Chapter Black, Raizen 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, Sensui would've likely killed Yusuke. ...Again.
• Curb-Stomp Battle: His three shown "fights" in the series consist of beating the piss out of Sensui, nearly killing Yusuke without even moving, and once again overwhelming Yusuke despite being literally minutes away from death. Only during the third one did his opponent even have a chance at taking him.
• Face Death with Dignity: After going completely berserk first...
• Handicapped Badass: A couple centuries of constant absolute fasting, and he's still the best around.
  Eniki: If Yomi and Mukuro saw Raizen in his prime, they would have peed their pants.''
• Glass Cannon: 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.
• Jerk with a Heart of Gold: Or perhaps a Hidden Heart of Gold. He's a demon who acts uncaring and hard-boiled but it isn't difficult to sympathize with his plight and good intentions underneath (but he doesn't exactly warm up to Yusuke until the end).
• Lightning Bruiser: Back when he had no problem eating humans, he had enough power to dispatch Yomi and Mukuro simultaneously.
• No Sell: Yosuke fired the Spirit Gun at him. It destroyed the wall behind him but he himself was unharmed.

• Red Baron: Hokushin refers to him as "The Master of War."
• Red Eyes, Take Warning: When he's so overcome by hunger, he goes into a berserk state.
• Soap Opera Disease: When we first meet him, he's already dying of selfimposed starvation.
• Story-Breaker Power: When he was in his prime centuries ago.
• Take a Third Option: Between devouring the Lady Doctor and dying, or killing her in vain... he chose to have sex with her.

• Walking Spoiler: Due to being Yusuke's ancestor.
• World's Strongest Man: At his peak he was the world's strongest demon, and still is: the only reason Yomi and Mukuro can compete with him is that being almost dead by starvation made his defenses subpar.

Teams in General

For details about Team Urameshi and Team Toguro, look under respective entries

---

• Opposing Sports Team: Most of the Teams that the heroes go up against are not motivated by evil desires and for the most part participate for the joy of fighting and the right to get a wish granted by the Dark Tournament Committee. The few genuinely evil people they go against, aside from Toguro's team, are Dr. Ichigaki (read his entry here for details) and possibly, if not evil then certainly amoral jerkasses, Roto and Bakken.
• The Team Benefactor: Each team is sponsored by a member of the Black Book Club with the exception of Team Urameshi which is sponsored by Koenma. However, two teams, those being Team Ichigaki and Team Uraotogi, are self-sponsored.

Team Jolly Devil Six/Team Rokuyukai

The first team of Fighters that Team Urameshi fought against in the Dark Tournament.

For Chu and Rinku, see Allies section above

---

• Blade Below the Shoulder: Roto can form a blade on his hand from one of his fingers.
• Complacent Gaming Syndrome: In-universe non-video game example. Roto's only strategy to winning involves threatening to kill an opponent's loved one if they retaliate.
  Roto: "Why go through all the hard work of becoming a better fighter when all you have to do is to press a button?"
• Dirty Coward: Roto who stoops as low as to try to try to have relatives of opponents killed via a Familiar. Though at least he did make an effort in contrast to Gaou and Imajin who fled the moment Hiei incinerated Zeru.
• Dragon-in-Chief: Zeru acted as the leader of the team in Chu's stead due to the latter's habitual drunkenness.
• Hostage Situation: Roto tries doing this to Kurama by using his human mother as the hostage during their fight in the Dark Tournament. It doesn't work for long.
• I Have Your Wife: Mother in this case. Kurama is forced to not retaliate against Roto lest Roto order the demon stalking his mother to kill her. Kurama manages to immobilize Roto, steal the trigger to signal the demon, then kill him.
• Off with His Head!: Chu, angry at Gaou and Imajin's cowardice in abandoning Rinku to fight Team Urameshi all on his own, took off their heads in one swift attack. The anime alters their death at Chu's hands as being beaten to death.
• Playing with Fire: Zeru's special ability, but it doesn't exactly hold a candle to Hiei's Dragon of the Darkness Flame.
• Punny Name: In addition to being a reference to a song (see Shout out below), Imajin's name is a play on the word "Majin" (meaning either "Demon" or "Evil person" depending on context).
• Rag Tag Bunch Of Misfits: Consisting of among other people a yo-yo wielding Child fighter, a Drunken Master, a Blue-skinned murderer and extortionist, and a blond fire wielder (and also an Edward Cullen fanboy before he even existed).
• Scary Black Man: Gaou looks like one.
• Shout-Out: Imajin has a strong resemblance to Musician John Lennon and his name is an allusion to his song "Imagine".
• Villains Want Mercy: Roto certainly wanted mercy, but Kurama wasn't going to let him go unpunished.

Team Spirit Warriors

A team that Younger Toguro fights and slaughters single handedly.

---

• Adaptation Expansion: Topaz gets more screen time and characterization in the anime.
• Bald of Awesome: Topaz. He may also qualify as an invocation of Bald Black Leader Guy.
• Canon Foreigner: Rugby, an alternate for the team, is a character that was created for the anime.
• The Captain: Topaz is the leader of the Spirit Warriors.
• Intrigued by Humanity: Rugby states this and more specifically says he has a liking of Human sports, particularly Rugby.
• Large and In Charge: Each of Spirit Warriors' members dwarf Younger Toguro, who himself isn't small in stature. Though that ultimately doesn't help them in the end. Rugby however averts this being of about the size of an average Human.
• Noble Demon: Topaz objects to Rugby's attempt to kill Yusuke outside of the ring and for that kills him.
• Red Shirt: The entire team is this, though Topaz at least gets upgraded to Mauve Shirt in the anime.
• Spikes of Villainy: Topaz wears a collar with spikes on it.
• Stout Strength: Dosukoi by default of being a sumo wrestler.
• Weapon of Choice: Topaz's is an ax, Gorira is armed with a hammer, Babaki uses a trident, and Gagaki wields a mace. Dosukoi is the only member who doesn't use a weapon. Anime-only character Rugby can create rugby balls.

Team Ichigaki

The second team of Fighters that Team Urameshi fought against in the Dark Tournament.

---

• Blinding Bangs: Yen (AKA M1).
• Braids of Action: Kai (AKA M2), a male example of this trope, wears his hair in a Mandarin Queue.
• Brainwashed and Crazy: What Dr. Ichigaki has done to three humans, via implanting berukis onto them, to use them as test subjects in exchange for healing their ill master Mitamura of which he was responsible for poisoning in the first place to force his students into accepting his deal.
• The Cameo: Yen, Kai, and Ryo (formerly M1, M2, and M3 respectively) are briefly shown in the bleachers watching the Final round of the Dark Tournament.
• Cyborg: Gatasubal, a cyborg demon to be more exact.
• Death by Adaptation: Ichigaki is strongly implied to have been killed in the anime, but the manga shows that he was still alive and witnessed the fight between Yusuke and Toguro. Inverted in the case of M5 who was killed in the Manga by Hiei and Kurama but is spared in the anime after getting them to the ring.
• Evil Redhead: Yen (M1). Subverted in that he is not inclined to evil but has been mentally enslaved by Ichigaki.
• Humans Are Special: Ichigaki is one of the few Demons to recognize the potential of Human Spirit power rather than belittling Humans as being inferior. However he fails to realize the potential of emotions, and firmly believes that Virtue Is Weakness.
• Lizard Folk: Minor characters M4 and M5 are reptilian humanoids.
• Mad Scientist: Dr. Ichigaki. We're not sure what university he got his doctorate from, but where ever he went really should do a better job of screening those people out.
• Mercy Kill: What Yen, Kai, and Ryo, upon being able to temporarily break though the control of their berukis, ask Yusuke to do to end their suffering, which he obliges. However it is subverted when Genkai intervenes and uses the Spirit Wave technique's Mortality Fatality function to destroy the Berukis without killing the fighters themselves.
• Mind-Control Device: The function of the Berukis.
• Must Make Amends: The three martial artist have stated that they wish to make up for having killed people while under Ichigaki's control. Ryo in particular offered to fight for Team Urameshi as his way to atone for his past actions.
• One-Winged Angel: Upon M1, M2, and M3's defeat, Ichigaki injects himself with a serum to take out retaliation against Yusuke. Instead, the doctor gets his ass handed to him.
• Put on a Bus: Upon being freed of Ichigaki's control, they return to train with their master and adoptive father Mitamura. Aside from a cameo of them cheering Team Urameshi in the final round of the Dark Tournament, this is their last appearance in the story.
• Shout-Out: Kai (M2) was modeled on Lau Chan.
• Slasher Smile: Ichigaki shows sadistic glee in seeing others suffer.
• This Is Unforgivable!: Inverted in that it is the previously antagonistic Yen, Kai, and Ryo who call themselves out. However Master Mitamura quickly tells them that they shouldn't blame themselves for being Mentally Enslaved by Ichigaki. Though this is certainly played straight against Ichigaki.
• Walking Shirtless Scene: Ryo (AKA M3) and thus has his Beruki in open sight in contrast to his teammates who wear shirts over theirs.
• We Have Reserves: He says this about M1, M2, and M3, considering that his real target is using Yusuke as a subject for his experiments. He doesn't care whether they will survive and that even if they were to win the Dark Tournament that he would simply kill them himself anyway.

Team Masho

The third team of Fighters that Team Urameshi fought against in the Dark Tournament.

For Jin and Touya, see Allies section above.

---

• Anti-Villain: The Shadow Channelers only wish to compete in the Tournament to, in Touya's words, "step into the light" to make a new home in the Human world. They qualify as Type IIs in that they regard themselves as True Companions. Completely averted in Bakken's case, though.
• Avenging the Villain: Not any of Team Masho's members' objective, but their sponsor, Butajiri, wants to get back at Tarukane's killers. Subverted in that he didn't give two craps about Tarukane, but Butajiri is a pompous Plutocrat who is pissed off at the audacity of a bunch of downtrodden Delinquents taking out a fellow Corrupt Corporate Executive and now wanting to "put them in their place". Though Sakyo corrects him that he was the one who ordered Toguro to kill Tarukane just before Toguro gave him a well deserved death as well.
• Bloody Murder: Gama's enchanted body paint is made from his own blood.
• Dishing Out Dirt: Risho can create a suit of armor by coating his body with clay from the ground.
• The Dragon: Jin serves as this for Risho.
• Elemental Powers: Gama's is blood based, Touya is An Ice Person, Jin's is wind based, and Risho's is Earth based. Bakken seems to have no particular elemental power.
• Evil Albino: Gama, though antagonistic albino would be a better description for him.
• Face-Heel Turn : Touya and Jin do this after the team's defeat.
• Four-Temperament Ensemble : Jin is sanguine, Risho is choleric, Touya is melancholic.
• Heroic Sacrifice: Gama may not exactly fit the definition of heroic, but he nonetheless sought to use his dying breath to place a concealment spell on Kurama to help his team achieve victory.
• Honor Before Reason: Toyed with. While Touya keeps to his principles demanding that Risho fight honorably in the face of blatant bribery and rigging of the match in their team's favor, the latter subverts this by choosing to be pragmatic and accept the ruling so that they can get closer to their goal of winning a new home in the Human world.
• Jerkass: Bakken is an unrepentant thug who is willing to beat down people who can't defend themselves and happily gloat about it. His personality is so grating that even his own teammates regard him as the The Scrappy in-universe. Thankfully, Bakken gets what he deserves from Yusuke.
• Kick Them While They Are Down: Bakken does this to an unconscious Kurama.
• Ninja: Or the "Shinobi of Spirit World" to be more exact.
• Real Men Wear Pink: Gama is referred to as being a "Master of Make-up".
• Smoke Out: Bakken can create a smoke screen with the vapor of his sweat.
• Smug Snake: Risho.
• Stripperific: Gama and Bakken wear little else than loin clothes and sandals. Justified as their abilities require their skin to be exposed in order to perform their techniques.
• Unintentionally Unsympathetic: In-universe example. This is the reason Bakken's Wounded gazelle gambit failed miserably.
• Wounded Gazelle Gambit: Bakken attempts to pull this on Yusuke once the latter gets the upper hand. Bakken pleads for mercy claiming that his ribs are broken and that he can't remember about the beating he gave to Kurama minutes earlier, in which he then tries to smash Yusuke's head with some debris. Yusuke never lowered his guard based on how inauthentic his pleas were and decided to "help remind" Bakken what he did to Kurama.

Team Uraotogi

The fourth team of Fighters that Team Urameshi fought against in the Dark Tournament.

For Shishiwakamaru and The Beautiful... Onji, see Allies section above.

---

• Adaptive Ability: Kuro Momotaro uses Steaming Spheres to gain an immunity to whatever attack was last used against him.
• Blade Below the Shoulder: Makintaro's only shown ability was being able to turn his hands into blades.
• The Dragon: While Shishiwakamaru appears to be the team's captain, he is revealed to simply be the Frontman for Suzuki.
• Fractured Fairy Tale: Its members are based on heroes from Japanese Fairy tales and folklore. Makintaro is based on Kintaro, Kuro Momotaro is based on Momotaro, Ura Urashima is based on Urashima Taro, and Shishiwakamaru is inspired by Oniwakamaru. Onji is the notable exception as he wishes, to paraphrase him, to make his own story. In an interesting coincidence Onji/ Suzuki's name in the Funimation English dub, "Suzuka", is similiar to that of the Mythological Suzuka Gongen. In addition, the team's name almost literally translates into English as "Team Fractured Fairy Tales".
• Full-Body Disguise: Two of its members are disguised. Ura Urashima is revealed to be a hairy canine-like humanoid shortly after he is killed by Shishiwakamaru and Onji is actually Suzu-ahem! The Beautiful Suzuki.
• Killed Off for Real: Makintaro, Kuro Momotaro, and Ura Urashima. Subverted in the case of Shishiwakamaru who Togashi intended to have been killed off at the conclusion of his battle against Genkai, but with the additional Three Kings saga his death was retconed as him being knocked unconscious.
• The Man Behind the Man: Onji/Suzuki is the true leader for Team Uraotogi.
• Manipulative Bastard: Ura Urashima claims that he was forced into villainy on the pain of his mother being killed during his fight against Kurama in order to get him to lower his guard to use his Idunn Box on him.
• Merlin Sickness: What Ura Urashima's Idunn Box inflicts on its targets and unwittingly brought about his defeat and near death when Kurama reverted to Yoko Kurama.
• Rag Tag Bunch Of Misfits: Who are empowered thanks to the weapons and equipment made for them by Onji.
• Reincarnation: Four of its members (See Fractured Fairy Tale above) claim to be the reincarnations of famous individuals as Demons.
• Telepathy: One of Ura Urashima's abilities.

Koto

The more prominent of the two hostesses of the Dark Tournament. Koto resembles a cat or a fox. At the end of the manga, the two and Ruka, the nurse of the Dark Tournament, become the "Cult Trio" and become widely popular on human television. She also has a crush on Toya.

• Cat Girl: Or Fox Girl (its ambiguous as to what animal-type demon she is).
• Combat Commentator: She first provided media coverage for the Dark Tournament.
• Cute Monster Girl: A cat-girl announcer.
• Dub Text: The dub gave her a crush on Kurama, or at least on his demon form.
• Even Evil Has Standards: Although she usually comes off as amoral, she does object to the dirty methods used by two of Team Masho's members, and goes surprisingly out of her way to save Juri from the Dragon of the Darkness Flame during Hiei and Bui's fight.

• Plucky Girl: Koto takes her job VERY seriously and continues to commentate even when the arena is falling apart around her.

Juri

The second of the two hostesses of the Dark Tournament, introduced in the Semi-finals. Juri resembles an amphibian. At the end of the manga, it's revealed that she has a crush on Suzuki.

• Bare Your Midriff: Wears a one-piece outfit with a large section around her belly cut out.

• Combat Commentator: She also provided media coverage for the Dark Tournament.

• Cute Monster Girl: A dragon-girl referee.
• Punch Clock Villain: Doesn't enjoy the job too much (given her cowardly nature), and prefers to look out for herself when the collateral damage becomes dangerous.

Ruka

Part of Team Mashōtsukai more or less. She can create barriers and tries to restrain Hiei and Genkai for several matches.

• Break the Haughty: Starts out arrogant but as Hiei gathers strength her nerve starts leaving her, then her cords start shreading.
• Defeat by Modesty: Started to go this route but sadly Kuwabara won before all of Ruka's cords were destroyed.
• Evil Redhead: Though more like Jerkass Redhead as she was simply a Punch Clock Villain overall.
• Hello, Nurse!: About every man's reaction to first seeing her. Even better she first steps out in a nurse uniform.
• Hoist by His Own Petard: Or in her case Hoist by her own cords, but narrowly averted. While she was able to able to restrain Hiei and Genkai behind her barrier, it also had an unbeknownst healing effect which Hiei benefitted from. Had Yukina not shown up at the right time, Ruka's life would have ended almost immediately after.
• Irony: She isn't a nurse at all, but her barrier ability happens to have healing properties she wasn't aware of.
• Ms. Fanservice: She even becomes a model (in-universe) as part of the "Cult Trio" with Koto and Juri.
• Squishy Wizard: While she can create barriers to protect herself or contain others, but if her cords are destroyed she will be left vulnerable to being killed.
• Stripperiffic: Starts out in a nurse uniform, strips it off to just cords around her chest and hips, along with high heels and hat. Apparently they can only work uncovered.

Natsume

• Action Girl: Among the old drinking and fighting pals of none other than Raizen, a Demon King just like Mukuro. Chu is completely smitten with her!
• Half-Identical Twins: She and her brother.

Kokou

• Action Girl: Among the old drinking and fighting pals of none other than Raizen, a Demon King just like Mukuro.
• Clingy Jealous Girl: Implied to be one since she still resents the Lady Doctor for snatching a place in Raizen's heart.

• Tsundere: She treats her husband Enki rather harshly, but then she breaks down crying in front of Raizen's tomb.

Enki

• Battle Couple: He and his wife Kokou are not just married, but also fighting partners.
• Big Fun - Nice Guy: Despite being a demon, he's very jolly and nice, and a good foil to his Tsun Dere wife. See also Noble Demon.
• Huge Guy, Tiny Girl: Is much larger than Kokou.
• Noble Demon: Wins the tournament and ends up making it the most peaceful place in ages, and yes he is a demon. Might be a subversion though, since he may not even count as a villain.
• World's Strongest Man: He's officially the World's Strongest Demon after defeating Mukuro and winning the tournament.

Maya Kitajima

Voiced by: Yuki Matsuoka (Drama CD's)

Kurama's underclassman who seems to have a crush on him and gets accidentally caught in the middle of his struggles. She only appears in the manga and the Drama CD's.

• Ascended Extra: Her very first appearance was during the Dark Tournament in a cameo in Kurama's flashbacks (not shown in anime) of his childhood in the middle of his fight against Ura Urashima. She later appeared in the Two Shot Special as a somewhat more prominent character.

• Damsel in Distress: While she does have slight spiritual powers, she cannot fight against demons ans has no martial arts knowledge.
• Laser-Guided Amnesia: Kurama wipes out her memories of her abduction at the end.
• Psychic Powers: She tells Shuichi Minamino (AKA Kurama) that she possesses spiritual awareness and could tell that he was special. However, she fails to detect the demon who apprehends her. Though this lapse could be justified in that she was distracted due to Kurama and Hiei's fight at the time.
• Sempai Kouhai: Wants to have a romantic relationship of this kind with Kurama.

Yatsude

Voiced by: ??? (Drama CD's)

The antagonist of the Two-shots Extra Chapter that explain how Kurama and Hiei met for the first time.

• Adapted Out: He makes no appearance in the anime, though a brief moment showing Kurama's and Hiei's first meeting from this special chapter is depicted in a blink-and-you'll-miss-it scene.
• Cannibalism Superpower: He can gain power, and possibly specific abilities, from consuming other live organisms. He particularly seeks to eat Kurama.
• Devour the Dragon: The "reward" he gave to the demon who captured Maya.
• I Have Your Wife: Or in this case, I have your classmate and an Ice Maiden. Subverted in the latter case as that was merely him taunting Hiei.
• Multi-Armed and Dangerous: He has six arms in total of which two protrude from his head.
• Posthumous Character: He was killed prior to Yusuke's death at the beginning of the story.
• Power Copying: Says he has this ability with his dying breath. He claims that if he had consumed an Ice Maiden he wouldn't have lost.
• Skeletons in the Coat Closet: He wears a belt consisting of skulls, of which are presumably those of his victims.
• Unskilled, but Strong: He is recognized as being powerful by Kurama, but demonstrates that he is not a good tactician which gets him killed.

Shigure

A very powerful and eccentric warrior and combat medic from the Demon World.

• Bunny-Ears Lawyer: Very efficient at work. His fees and charges are very... personalized. In the case of Hiei, he first demands to listen to his life story and reasons, and then makes him promise that he will never tell Yukina of their bond.
• Combat Medic: Both a badass combatant with his Rings of Death and an extremely efficient surgeon who actually implanted the Jaganishi in Hiei's forehead.
• Death by Adaptation: He's killed off in the anime, whereas he survives in the original manga.
• Driven to Suicide: Anime only, since he pretty much throws himself off the huge tree grown in the stage after Kurama defeats him.
• Go Out with a Smile: At least he wasn't that unhappy as he kicked it.
• Rings of Death: His Weapon of Choice.
• Walking Spoiler: More exactly, what he did in the past completely shaped Hiei's motivations and storyline.

The Lady Doctor

A human woman from Raizen's past. And Yusuke's ancestress.

• Aloof Dark-Haired Girl: She was a tall and beautiful woman with long dark hair and a no-nosense attitude.
• Death by Childbirth: The Lady Doctor was impregnated by Raizen in their first and only time, then died when their baby was born.
• Dress Hits Floor: When Raizen shows up at her home with the clear intention of eating her, she pulls this on him with her kimono... but in a subversion, it's to show him how her body had been ravaged by disease and prove him that, should he eat her, he would regret it. Not that we actually get to see that.
• Hot Witch: Some translations of the manga have referred to her as being a "witch", though the "Hot" is not as disputed in-universe at least. Thus when her lover awoke to justice, the Dark Knight Spar-Oh, sorry, wrong story.^note For those unfamiliar with Devil May Cry and possibly don't understand, Eva (the one from the classic continuity, not to be confused with her angelic counterpart in Dm C Devil May Cry) was a witch who fell in love with the Demon Sparda, of whom the protagonist is one of two products of this union, somewhat like the Lady Doctor's relation to the spoiler protected individual.
• Interspecies Romance: With the super powerful descendant to show it, too.
• The Lost Lenore: For Raizen. After their single night of sex, he swore off his demon-womanizing (much to the displeasure of Kokou) and, having learned about her Death by Childbirth, he decided to never eat any humans until she was reincarnated and he found her again.
• The Medic: Said to be a skilled healer.
• No Name Given: We never learn her name, in fact "Lady Doctor" is her Fan Nickname.
• Poisonous Person: She was a "shaman cannibal" who willingly consumed the flesh of people who died of illness so her body would develop antibodies and eventual cures, which doubled self-defense against human-devouring demons. If any demon had a piece of her, they'd die painfully and slowly since her flesh was ripe with disease.
• Posthumous Character: As she is a human who lived centuries before the present of Yu Yu Hakusho.
• Regret Eating Me: She told this to Raizen. The reason is resumed in one trope: Poisonous Person
• Small Role, Big Impact: Her role in Raizen's life pretty much put the whole story in movement.
• Tsundere: Raizen has described her as having a fiery temper and says that Yusuke inherited that personality trait from her.
• Walking Spoiler: Because, as said above, her small role was vital in the story.

Sei-Sei Shinto (AKA The Armed Church of the True Disciples)

The last enemies that Team Urameshi fought against in the story.

---

• Adapted Out: The Sei-Sei Shinto, which appeared in Chapter 174 (the next to last one) in the manga, doesn't appear in the anime.
• Big Bad Wannabe: Ōtake, the former Captain of the Special Defense Forces who was removed by King Enma for failing to kill Yusuke, is the leader of the Sei-Sei Shinto.
• The Coup: In this case, the True Disciples goals is to to restore the Deposed ruler Enma back onto the throne.
• Death Ray / Wave Motion Gun: What they plan on using as their Final Solution against Sarayashiki, Japan if their demands are not met.
• Does This Remind You of Anything?: Their opposition to the changes brought about by the new Spirit World government led by King Koenma is strongly reminiscent of Right Wing Militia Fanatics that were active during The Nineties. In addition their head grabs closely resemble Keffiyehs that are worn by people of the Middle East. Their goals are described, via the Viz Media English translation, as follows: "They believe they are on a Holy mission from god to purify the Human world. The True Disciples follow the most extremist (sic) version of their teachings".
• Evil Reactionary: Now that the status quo has been changed following King Enma's impeachment and removal from the throne, they seek to restore the previous order at all costs.
• Fantastic Racism: Against Demons who they still regard as being Always Chaotic Evil even after that was definitively disproven. The Sect also has some contempt for Humans in viewing them as being immoral and undeserving of running their own lives. Team Urameshi would beg to disagree.
• Gas Mask Mooks: Most of the Terrorists wear Gas Masks.
• Hostage Situation: Of whom notable individuals they are holding at gun point include Koenma and Botan.
• I Reject Your Reality: They refuse to accept that King Enma was responsible for brainwashing and using Demons to justify his so-called "protection" of Humans and now wish to restore Status Quo Ante regarding that revelation as never having happened.
• Knight Templar: The Sei-Sei Shinto are a radical Spirit World religious sect that take over the Gates of Judgment in the Spirit World to "purify" the Human world.
• Light Is Not Good: Spirit beings, such as Koenma and Botan, have for most of the series been portrayed as allied with the forces of good against Demonic threats. In this instance it has been flipped with some of Spirit World's Denizens as the antagonists.
• The Magic Versus Technology War: In this case, Sei-Sei Shinto's Spirit World Magitek against Team Urameshi's members' Supernatural Martial Arts. Despite outnumbering the heroes thirty-three to four, the True Disciples were easily beaten. The Interdimensional laser, on the other hand, remained as one thing Team Urameshi could not over come with brute force.
• Order Versus Chaos: They are the order to the perceived anarchy of Demons. Though the order that Sei-Sei Shinto wishes to impose would better be described as Tyranny.
• Politically Incorrect Villain: Of a more Fantastic variety.
• Superior Species: What they believe to be the case with Spirit World in regard to its inhabitants' "right" to rule over Humans.
• Undying Loyalty: For the ultimate villain of the series King Enma.
