Despite his stunning victory at the Dark Tournament, Yusuke Urameshi learns firsthand that there are others wishing to challenge him. Yusuke makes the first mistake by underestimating the strengths of these new adversaries. With his best friend kidnapped, Kuwabara must round up the old gang in order to stage a rescue attempt...or suffer the consequences!

After much convincing, Hiei joins Kuwabara's crusade to save his kidnapped comrade. Upon reaching the mysterious Rokurokubi Estates, the three discover Kaitou, who quickly explains the rules of his territory. Can Kuwabara, Kurama, and Hiei be of any use in a place where any form of violence is strictly prohibited.

Kaitou's devious game becomes a fight for survival as Hiei, Botan, and Kuwabara all fail prey to the twisted teen's bizarre rules. But Kurama issues a challenge...one by one the letters of the alphabet will become taboo. If any of the taboo sounds are uttered, the speaker will face a terrible penalty. Placing his own soul on the line, Kurama prepares himself to battle wits with the brilliant Kaitou.

Kuwabara and the gang finally reach the room where Yusuke is being held captive. But Kido has one final game to play with the Spirit Detective. One of his friends is in fact an imposter, and Yusuke has only minutes to determine which one it is! With his decision made, Yusuke attacks!

A tunnel is being carved between the Living World and the Demon World that if completed would usher in such darkness and chaos that the world might never recover. In a bold move, the despicable Sensui begins his search for the person that will finally allow him to complete the tunnel.

The Spirit Detective's best chance to uncover the truth behind the tunnel lies with the mind reader, Murota. But mere hours after entering Mushiyori City, Yusuke and team find themselves being hunted by an unseen evil. Just who are Black Angel, Gate Keeper, Sniper, Gourmet, Game Master, Doctor, and Sea Man?

Somewhere in Mushiyori City, a psychic is forging a tunnel between the Demon and Human worlds. Yusuke has recruited Murota, a mind-reading human. But while trying to weed out the enemies by their thoughts, Murota was shot -- and the criminal mastermind made his introduction. The heroes have taken Murota to the hospital, where new danger awaits.

Searching Mushiyori City, Yusuke's team was quickly steered to the hospital, where a trap awaited. There they encounter the Doctor, a human with immense psychic powers, super strength, feels no pain, and has infected the entire hospital with a deadly virus. To save his friends, will Yusuke be forced to destroy the wretched creature?

As Sensui's plan continues, Kuwabara and his friends attend a rock concert. However, they are ambushed by Sensui's next minion: Seaman, a person with the ability to create monsters out of water. With his friends held hostage, Kuwabara must battle Seaman alone...

Kuwabara's battle with Seaman continues.

Shinobu Sensui, the former Spirit Detective, is revealed to be the mastermind behind the plot to remove the barrier to Makai. Koemna discusses his fall into insanity with Yusuke's group.

Sensui makes his appearance, and battles Yusuke, Kuwabara, and Kurama. Sensui's abilities enable him to battle all three on equal footing. During the battle, Sensui manages to kidnap Kuwabara.

As Yusuke continues his chase of Sensui, the unbelievable Sniper confronts Yusuke. As Genkai and the rest of the team follow, can Yusuke escape Sniper's endless barrage, reach Sensui and save Kuwabara... not to mention, the entire human race?

Yusuke continues to evade Sniper's dangerous attacks, but the horrible villain may still have a few tricks up his sleeve. Meanwhile, Hiei has finally returned to his former teammates to join in their crusade, but will that be enough to free Kuwabara before Gourmet can consume his power, and tear the Kekkai Barrier to shreds?

Yusuke, Kurama, Hiei, and Mitarai enter a cavern controlled by the tricky Gamemaster. Gamemaster's territory can be manipulated into a video game, a game where everyone must play by the rules in order to survive. Yusuke's team must win 4 rounds to move on, but is a victory possible against an adversary who can manipulate the rules?

Yusuke's team has won the first round, but they'll need to win three more to defeat the Game Master and move on to Sensui's lair. The hole to the Demon World is rapidly expanding. Can they make it there in time to prevent the end of the world?

Only two hours remain before the tunnel opens unleashing a horde of hungry demons upon the world of the living. Kurama steps forth to battle Gamemaster for the right to move on to Sensui's lair and Yusuke senses that one of them will not make it out alive.

Yusuke and his entourage have made it to Sensui's lair, but their battle to save the human race is just beginning. The opening to the Demon World is widening rapidly and shows no signs of slowing down. What's more, an old nemesis reveals his own master plan. His target, Kurama!

Kurama's anger has sentenced Toguro to an eternity of suffering, forever chasing his foiled revenge. But the tunnel to Demon World is opening. Can Yusuke's team still save the human race? Only a dramatic showdown between the past and present Spirit Detectives will reveal the truth!

As the epic battle between Yusuke and Sensui continues, Yusuke learns that he is no match for the former Spirit Detective. As Sensui prepares the finishing blow, aid comes in a most unexpected package. And what is the truth behind Sensui's unique personalities?

As Itsuki explains more about the bizarre Sensui, Koenma prepares to use his most powerful weapon: his pacifier! It can create a barrier that would stop the demons from flooding Living World. Koenma knows that Sensui must be stopped or his evil plan will come to fruition dooming the entire human race!

Koenma's tactics have saved Yusuke for now. But mysteriously Yusuke won't allow the Prince of Spirit World to use his pacifier. While they discuss their next move, the terrible gateway between Demon World and Living World opens.

Yusuke comes to terms with the fact that he cannot defeat Sensui. Watching but unable to help, Kuwabara fights off emotion with rage as he remembers all the good times and bad he's had with his best friend. Kuwabara manages to free Kurama and Hiei, but it's too late. Yusuke Urameshi has been destroyed.

Too late to save their friend's life, Kuwabara, Kurama, and Hiei unleash their most devastating attacks on Sensui, who retreats within the tunnel. King Yama reveals a dark secret to Botan. What news would cause her to tremble in terror? What does King Yama know about Yusuke that the others do not?

With no thought to their own safety, Kuwabara, Kurama, and Hiei charge deep into the tunnel in an effort to rid all worlds of Sensui forever. Meanwhile, King Yama's soldiers arrive to take Yusuke's body away to ensure he is never revived. As Koenma does his best to stop them, help arrives on the horizon in a very different form.

After being saved in the nick of time by Puu, Yusuke revels in his new power and resumes his battle with Sensui. Although Yusuke's skill and strength have increased, he is still clumsy with his new abilities. But there is no time to practice as Sensui bears down for the final confrontation.

Yusuke's body has undergone an intense transformation as his dormant demon blood takes hold. As the battle against Sensui concludes, Koenma tells Yusuke that he must choose between Demon World and Living World. Without hesitation, Yusuke makes his decision!

Yusuke and team return topside to the waiting arms of their friends. But all is not well. King Yama's soldiers arrive saying that they must destroy Yusuke once and for all. Could this be the end? How much energy does the Spirit Detective have after his exhausting battle with Sensui?

Toguro wants Yusuke to enter a competition called the ""Dark Tournament"". Compiled of a group of greedy mafia warlords, Toguro convinces Yusuke, as Yusuke gathers Kurama, Hiei, and Kuwabara for his team, the gang sets out to compete in the tournament.

As Team Urameshi boards the ship to the Dark Tournament, the preliminary round begins.

Botan, Keiko, and Shizuru, Kuwabara's sister, arrive at the tournament site to watch Team Urameshi duke it out with their first opponents, Team Rikkuyukai.

Kuwabara continues his battle with Rinku.

The Rikkuyukai team leader, Zero, stands up to fight. Hiei steps up, saying he'll take him on.

Yusuke begins fighting the drunken Chuu, the final fighter from the Rikkuyukai Team.

Yusuke continues his fight with Chuu.  Meanwhile, Keiko and Shizuru get lost in a catacomb of hallways inside the arena.

Having won their first round, the Urameshi Team has a day to rest while they wait for their next opponents.

The battle begins between the Dr. Ichigaki Team and the Urameshi Team. Since the other two members of the Urameshi Team, Kurama and Hiei, haven't shown up yet, the doctor suggests a 3-on-3 battle.

The Urameshi Team continue their fight against the Dr. Ichigaki Team.

The Urameshi Team confronts Ichigaki himself.

Only minutes after Yusuke's victory in round two, the faceless tournament commitee makes a jarring anouncement. Team Urameshi's next match will begin immediately against Team Masho, five demons veiled in black cloaks.

Kurama's battle continues.

Kurama's battle concludes.

Yusuke battles Jin, the Wind Master.

Yusuke's battle with Jin concludes.

Kuwabara battles Risho.

Yusuke is confronted by Botan about the hatching of his Spirit Beast.  The Masked Warrior's identity is revealed.

Genkai tells Yusuke his final test is to kill her.

Yusuke is still in the midst of Genkai's Spirit Wave Orb absorption test. Meanwhile, Hiei battles Kuro Momotaro in the arena.

Hiei continues his struggle against Kuro Momataro and Kurama's battle against Ura Urashima begins.

With both Ura Urashima and the newly transformed Yoko Kurama trapped in the ring, the true battle begins.

Kuwabara starts his battle against Shishiwakamaru.

The match between Shishiwakamaru and Genkai begins.

In the last match against Team Uraotogi, Genkai overwhelmed Suzuka, an old demon with many tricks and specialties, but little strength. Meanwhile, Yusuke recovers from the torturous absorption of Genkai's Spirit Wave Orb, which promises to give him unfathomable power. Yusuke's team has claimed their spot in the Dark Tournament's final round. Now Team Toguro must try to do the same.

The members of Team Toguro demonstrate their power in the semifinals.

Fifty years ago, Genkai and Toguro were actually teammates who fought and won their own Dark Tournament, before becoming violently estranged. Yusuke Urameshi arrived just in time to see his teacher slain, and assaulted Toguro in a rage, only to be knocked away by one devastating blow. With the final round of the tournament soon to begin against Toguro, Yusuke must find a way to keep that from happening again.

Shortly before the final round of the Dark Tournament, Yusuke's mentor Genkai was killed, leaving him with all of the Spirit Power she possessed. Since then Yusuke and his crew have been rigorously training for the upcoming battle. Suzuka, a member of the recently beaten Team Uraotogi, has helped by offering two very powerful, yet unstable weapons, hoping that Team Toguro will finally taste defeat.

The tournament finals are set to begin. But the rules state that each team must have five members to compete. With each team having only four fighters, two competitors step up to join with each team no matter what the consequences. Who are the two new fighters and what could they possibly bring to the team?

The Dark Tournament finals have just begun and Kurama finds himself facing the strangely magnetic yet dangerous Karasu. Kurama, believing that it's his only chance to defeat his eerie opponent, transforms himself into the powerful and equally ruthless Yoko Kurama. Things seem to be looking up, but will Kurama's metamorphosis be enough to conquer Karasu?

With Karasu able to counter Yoko Kurama's attacks, the vicious member of Team Toguro is set to take the victory. Taking his own life into his hands, Kurama prepares to sacrifice his life energy in a final chance to defeat the demon. But with no life energy remaining, Kurama may stay down forever.

A disappointing verdict is handed down in the Kurama versus Karasu match, reversing Team urameshi's fortunes in the Finals of the Dark Tournament. Hiei seeks to recover from this setback in the ring with Bui, but will the power lurking beneath Bui's armor be too much for him?

Hiei unleashes his most powerful attack, the Dragon of the Darkness Flame! But Bui is able to turn the Dragon against his master. Will Hiei be swallowed and destroyed by his own power?

During his match with Toguro, Kuwabara is told of Genkai's death. With extreme rage Kuwabara strikes Toguro with the Trial Sword splitting the demon in half! The arena watches in horror as the evil Toguro rises from the arena floor unharmed.

Kuwabara's fight with the elder Toguro brother comes to a smashing conclusion, leading into Yusuke's grudge match with the younger Toguro. But before that bout can begin, intrigue at Team Toguro culminates in a shocking proposal from Sakyo and an even more shocking response from Koenma!

The ultimate showdown between Yusuke and Toguro finally begins, and everyone is on the edge of their seats -- at least everyone that hasn't been melted into their seats by Toguro's intense Spirit Energy. Yusuke reveals the power he inherited from Genkai with a colossal blast of his Spirit Gun, but is it enough to bring down Toguro once and for all?

Yusuke reveals to Toguro that he has not been fighting at full power and removes the Spirit Cuffs, which reduce his power. Finally, a fully powered Yusuke launches an attack at his nemesis. But Toguro too has powered up to his top level and stares down Yusuke's most powerful Spirit Blast.

As Yusuke lies beaten on the arena floor, Toguro taunts the Spirit Detective. Toguro begins to suck the souls of the spectators in order to enrage Yusuke to once again bring out his full power. But Toguro soon learns that the best way to provoke Yusuke is to kill one of his friends!

As one of his friends lies on the arena floor, Yusuke powers up to the same level as Toguro. To defend himself, Toguro must power up to 120% of his capacity. Can either fighter, each completely devoid of any remaining energy, survive to claim the prize?

With the Dark Tournament at an end, Yusuke must beign to cope with the loss of his best friend at the hands of Toguro. After Sakyo asks Koenma to take his life, the evil billionaire unveils his final evil plan to destroy the entire stadium with everyone still inside!

Team Urameshi prepares to depart Hanging Neck Island the victor of the sinister Dark Tournament to return to the world of the living leaving their fallen mentor and friend behind. But somewhere far away a chance encounter between two former allies seems to hint at what is to come as the most unlikely of people reveals a most shocking secret.

Yusuke Urameshi is having a typical day. He's cutting class, arguing with teachers and getting into fights with his rival Kuwabara. But then Yusuke does something that betrays his killer rep. He dives in front of a speeding car to push a little boy out of harm's way! Yusuke has sacrificed his life for the sake of another, but is this really the end of this brash young man?

Pulled by the sprightly, pink-robed Botan, Yusuke enters a realm that is not quite normal -- the Spirit World. There, Yusuke meets Koenma, a 700 year-old ruler with the body of a toddler, pacifier and all! But there's no rom for laughs as Koenma gives Yusuke an ordeal to restore his life. Hatching a Spirit Beast!

Kuwabara was tormented by his rival's death. The loser in all 156 of his brawls against Yusuke , he's now lost any chance he ever had of evening the score! But with Yusuke out of the way, Kuwabara is the new kid to beat... which means he's making plenty of enemies. Yusuke isn't fond of this classmate, but if he wants to win back his life, he will need to give him a ghostly hand.

The Spirit World forgot an important question -- does anyone want Yusuke back? Koenma sends an Investigator to find out, and Yusuke's friends answer quickly when a fire threatens to char his earthly body. But will Yusuke give up the Spirit Beast, his one chance for revival, to rescue his friends?

Yusuke has reclaimed his life, but has only one day to be revived by someone's kiss -— And that someone might be Kuwabara! Back in the flesh, Yusuke finds he can see supernatural creatures hiding in the living world, and quickly hunts down a demon criminal. With this move, he learns his adventure is only beginning. Yusuke is a Spirit Detective.

Yusuke receives his first real case as Spirit Detective. Three demon thieves have muscled their way into King Yama's sacred vault, stealing the three Artifacts of Darkness. Yusuke must recover the artifacts and bring the thieves to justice before they unleash dark and deadly powers on the people of Earth.

The oafish demon Gouki is using the stolen Orb of Baast to capture children's souls. If Yusuke doesn't track down and defeat this monster quickly, those souls will become the monster's next meal. But Gouki isn't the only one Yusuke has to worry about when the second thief suddenly appears. His name is Kurama, and to great surprise, he asks Yusuke for a favor...

With two artifacts under his belt, Yusuke heads for his most dangerous challenge yet – the ruthless demon Hiei. But unbeknownst to Yusuke, Hiei is chasing him, and kidnaps his girlfriend Kayko! Unless Yusuke can retrieve the antidote inside Hiei's Shadow Sword, Keiko will become a brainless, monster slave! Can Yusuke close the case?

Yusuke's three-day weekend is cut short when Botan delivers his next big case. Genkai, an aging psychic, will hold a contest to find a worthy apprentice to her powerful technique: the Spirit Wave. But an evil demon, Rando, plans to steal the technique and use it for mass destruction! Yusuke must go undercover and infiltrate Genkai's compound!

The candidates for Genkai's apprenticeship have been narrowed to eight. Among them: Yusuke, Kuwabara, and the disguised demon Rando! Genkai announces the final test will be a tournament, fought in total darkness. And Kuwabara's first opponent is swinging a supernatural sword!

In his first match of the tournament, Yusuke faces an impossible disadvantage. He can't see a thing in the pitch-black arena, but a hi-tech helmet allows Kibano to follow Yusuke's every move. Even if the battle-worn detective can survive Kibano, he'll have to fight his second match immediately -— against a lethal ninja!

Yusuke, Kuwabara, and young Shorin are the only fighters still standing in the Genkai Tournament. Yet Rando has not been found. Could this mean that Shorin is actually Rando? Or is the demon lurking somewhere in the shadows? The truth will soon be known, as Kuwabara faces Shorin on the haunted field of battle.

Kuwabara's body lays broken. Shorin is nowhere to be found. And with Yusuke's energy dwindling every minute, the evil Rando reveals his true and monstrous form. Now, can the injured Yusuke battle the human-hunting demon and close the case? How can he, when Rando has ninety-nine deadly techniques in his arsenal.

Yusuke returns from training with the great psychic Genkai, and not a moment too soon! Dreadful Makai Insects are invading his own city, part of a sinister scheme to flood the earth with demons! With Kuwabara at his side, Yusuke dives into a forbidden demon city. His target: four deadly creatures known as the Saint Beasts!

Kurama and Hiei, two demons Yusuke beat in his first case, join Yusuke and Kuwabara to battle the Saint Beasts. This awkward alliance must learn to trust each other quickly, as they struggle through the Gate of Betrayal. And waiting just beyond this trap is the first Beast —- a giant made of solid stone!

One of Yusuke's teammates has been badly injured, and Kuwabara insists on fighting the next enemy all by himself -— revealing his amazingly improved Spirit Sword! Before the bickering group can disagree, a ferocious roar slices through the castle. Byakko, the second Saint Beast, is waiting!

After a harrowing fight on a collapsing bridge, Byakko is seemingly defeated. But as soon as the Spirit Detective team enters the castle's next wing, a fearsome tiger roar bids Kuwabara to round two -- in Byakko's secret lair. Can this Beast be beaten once and for all, in a room of molten lava?

Two of the four Saint Beasts are dead -- or so Yusuke and his team believe! But in the chamber of Seiryu, a Beast who can trap his enemies in ice, an unexpected guest arrives. How can two Beasts in one room be stopped? And why is Hiei, a cold-hearted rogue, suddenly beset with emotion?

Yusuke, Kuwabara, Kurama and Hiei rush into the next part of the castle as they reach the final chamber where Suzaku awaits. Unknown to them Suzaku's master plan is being made - to capture Keiko.

Suzaku uses The Prism of Seven technique to create seven Suzakus. Not merely copies, each one has independent will and full powers - all aimed at the torture and annihilation of Yusuke.

Suzaku releases another lightning fist attack, but Yusuke was up to the task as he himself unleashes his full power and he blasts Suzaku with his devastating spirit shotgun!

Yukina is a beautiful ice apparition whose tears transform into priceless jewels. Now a filthy human crime lord named Tarukane has kidnapped Yukina, planning to extract her tears through torture and make a fortune! Yusuke, Kuwabara, and Botan must quickly mount a rescue mission. But why is Hiei not allowed to know?

Yusuke's Spirit Detective team continues toward Tarukane's mountain stronghold, facing a small army of grotesque demon guards. It seems an alliance has formed between human criminals and demon mercenaries, with money as the bottom line. Yet Kuwabara plows fearlessly ahead declaring he's in love with Yukina!

Struggling their way to the front gates of Tarukane's stronghold, Yusuke, Kuwabara, and Botan now face a much greater challenge: three notorious demon fighters known throughout Spirit World as the Triad! Can the Spirit Detective team fight three outlandish opponents on after another, and save the tortured Yukina?

One giant battle stands in the way of rescuing Yukina. Yusuke and Kuwabara versus the leaders of the demon mercenaries, the immensely powerful and bizarre - Toguro Brothers! What will it take to defeat the freakish duo in a fight where anything goes? Elsewhere, Kurama races to stop Hiei, who is entering Tarukane's stronghold with his own violent agenda!
