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!

Having rescued Yukina and defeated Toguro, Yusuke is spending some time with Keiko in the city. However, when a huge chunk of building is blown up, Yusuke sees Toguro, and they have a little chat. Turns out that Yusuke and Kuwabara really didn't defeat the Toguro brothers, as they were faking and working for Sakyo, and now 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, the preliminary round begins. The Masked Fighter is the one to fight, as she knocks out the demons with a Shotgun, causing a riot against Team Urameshi on the ship. The team then begins to fight, knocking out many demons, even killing a few, when they reach Hanging Neck Island. When they reach their hotel room, they are greeted by two mysterious characters, from Team Rikkuyukai, the team they are to face in the first round of the tournament.

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. Koenma is there as well, and reveals an adult form, to impress everybody since he's tired of being called a toddler. Everyone takes their seats, and the kid with the colorful outfit, whom Team Urameshi met last night, Rinku, steps up to take the first match. Since Yusuke still seems to be asleep, Kuwabara takes the first match. The match begins, and Rinku demonstrates his incredible speed by running in flashes around Kuwabara. Kuwabara's training pays off, however, when he can easily detect Rinku's movements. He deals him a few crushing blows, and it looks like Rinku is down. He grins, though, standing back up and telling Kuwabara he was just playing around to begin. He reveals his true weapon, eight Yo-Yos, four for each hand. He launches them forward to Kuwabara. Kuwabara reveals his newly-improved weapon, double Spirit Swords.

Kurama takes on Roto after the end of Kuwabara and Rinku's fight. Roto earns Kurama's wrathful vengeance by taking his mother hostage.

Hiei takes on Rokuyukai’s leader, Zeru, whose explosive fire attacks ravage the stadium. Hiei must resort to an unbelievable technique, one that could take his life as well: he must summon the power of a dragon.

Yusuke jumps out of his slumber, ready for the final fight against a new fighter named Chu. He’s rude, he’s crude -and he claims to be Team Rokuyukai’s true leader.

Yusuke and Chu, both drained of their Spirit Energy, struggle to win the first round of the Dark Tournament for their team. They agree to settle it with a Knife Edge Death-Match, an intense and fatal arena of combat.

When he’s ambushed by a loose-cannon competitor, Yusuke learns that even quiet moments on Hanging-Neck Island are dangerous. Meanwhile, Hiei faces the consequences of his deadly dragon attack.

Round two of the tournament arrives and Team Urameshi must face Dr. Ichigaki’s fighters, a group with a habit of chopping off their opponent’s heads! Will Yusuke be the doctor’s next guinea pig?

During a three-on-three battle, a rip on the Masked Fighter’s headdress gives a surprising peek into the warrior’s true identity! But there’s little time to ponder the ramifications, as Kuwabara now refuses to fight!

The doctor’s human experiments are clearly fighting against their will! As Yusuke prepares to put them out of their misery, the Masked Fighter intervenes and suggests a peculiar plan.

After Yusuke and the others make it to the third round, Hiei and the masked fighter get tricked and trapped inside a force field.

Okay, brief recap to what happened last episode: Kurama has just had his arms and legs frozen, but used his spirit energy through his hair when he used the rose whip to slice Gama apart. And like in the last episode, Gama tries to hit Kurama through his wounds, splattering his blood all over him. Right before he dies, Gama tells Kurama that his blood has sealed his spirit energy. Uh-oh. To make matters worse, the next member, Touya is ready to fight and avenge his dead teammate. Touya attacks just as Gama's first spell wears off, allowing him to move, but with his energy still sealed, he's still in a bad situation. Kurama spends all of the time trying to keep himself from getting killed by Touya's attacks. Eventually, he forms a plan to defeat Touya, and gets himself cut on purpose to plant one of his death plant seeds inside his own body right so it can manifest as a weapon.

Kurama is unconscious, and getting beaten to death by Baken. The announcer Koto tries to give a 10-count to stop the fight, but Baken ignores her and kicks her out of the ring. Just as Baken is about to kill Kurama, the team captain, Risho, tells him to stop. As it turns out, Yusuke was about to fire his spirit gun right at Baken if he had tried to kill Kurama. Kurama then is tossed out of the ring. Baken is declared the winner. Yusuke then gets onto the ring to confront him. Baken uses a technique built from his sweat to cover the entire arena in mist, so Yusuke won't be able to see now. Baken delivers a few blows, but the barely harm Yusuke, and he then fires a spirit gun through the arena, causing the mist to vanish.

The episode starts with Jin in the air, admiring the island. He swoops down and flys by Yusuke. Yusuke turns around and takes a punch to the face. He tries to counter with a kick but misses. Jin pulls out his signature move, the Tornado Fist. It is literally a tornado on his wrist. The punch misses Yusuke but the force pushes him back. Yusuke goes the hand to hand combat. Jin blocks everything but one punch. He flees into the air and recovers. While he is recovering, Yusuke shoots a spirt gun. Jin makes a tornado around him and deflects it. On the sideline, Botan realizes the Yusuke can't fight close and far away. Koenma is concerned because Jin uses wind for offense and defense. Jin comes down with another Tornado Fist. Yusuke doesn't even move. When Jin is at pointblank, Yusuke fires spirit gun into the Tornado. There is a huge explosion. Yusuke is blown back to the medical tent. Hiei tells him that Jin blocked with the Tornado Fist, saving both of their lives.

This episode starts with Jin in the air with his Double Tornado Fist ready for the kill. All of a sudden Yusuke says, ""Time for something stupid."" His body becomes surrounded with spirit energy. Everyone is surprised-Botan, Kuwabara, Kayko, Koenma. Then Jin attacks with the first tornado fist. Yusuke somehow catches the fist. Jin exclaims, ""No one can catch a tornado!"" Yusuke throws the fist, rendering it useless. When Jin attacks with the second fist, Yusuke catches it with his foot. He also makes the Tornado Fist useless. He yells, ""SPIRIT WAVE"" and a punch full of blue energy nails Jin right in the stomach. Jin goes flying in the air. The Masked Fighter explains that the Spirit Wave is like Yusuke's shotgun attack and that he must have learned it from Genkai. In the stands, Kayko is shocked, but Shizuru says, ""Let's move."" All of a sudden, a sparkle is seen in the sky and Jin's body comes crashing down in the stands. Koto makes a ten count, and Yusuke is the winner.

This episode begins with the fight between Risho and Kuwabara underway. Risho is beating the crap out of Kuwabara, who can't even use his spirit sword. Outside Shizuru, Kayko, Botan and Yukina are trying to get back inside. The demon security guard won't let all four back in, so they show him some human butt kicking. They get chased by more security guards unless they see Toguro. Yukina has flashback to her kidnapping. Toguro, however, lets the four go by. He wants the Urameshi team to win because he wants a rematch with Yusuke, as Sakyo promised. Eventually Kuwabara get cocky and forces Risho to show his Shinobi strength. Risho is the Master of Earth. He holds up his finger and the ground shakes. Risho uses his Armor of Clay techinique to cover his body with earthen armor. He jumps up in the air and crashes into the ring like a giant meteor. Kuwabara refuses to go down. Eventually Kuwabara realizes he can't win. He decides to use his life energy like Yusuke did against the final Saint

After talking to Kayko, Yusuke is confronted by Botan. She tells him his Spirit Beast will hatch soon. Koenma startles the two and show Yusuke his big egg. Koenma reminds him that the egg will consume every part of him if he was evil. The egg hatches and no one sees where the beast is. They look at Yusuke and they see the beast. It is a small blue bird with big floppy ears. Everyone mocks him. The next day, the team trys to scope out the competition. Team Uraotogi takes care of Team Gokki 6 in two minutes. Only the badly injured Hiei and Kurama watch the fight. Kuwabara tells them to go to Yukina for healing, not knowing she is Hiei's sister. He mentions her quest and Yusuke and Kurama starts mocking Hiei. Then, Team Toguro shows up. Toguro and his younger brother are there, as well as a guy in black with mask (Karasu) and a guy clad in armor (Bui). The crowd gives them praise. Then Yusuke and the Masked Fight get into a fight. She says she would be a better leader than Yusuke.

Genkai tells Yusuke his final test is to kill her. Yusuke has second thoughts. He meets Genkai in a cave and says he can't do it. She tells him that was the first part of the test. She would not give her power to someone who would kill her. She reveals her source of power is her Spirit Wave Orb. She takes out a bright ball of energy. Yusuke's test is to absorb it. He agrees to the terms, though the test could kill him. She puts it in him. He feels nothing at first, but then he collapses and pain. In a new ring, the semifinals begin. Team Urameshi enters, missing two of their members (Genkai and Yusuke). They are facing Team Uraotogi. Hiei and Shishiwakamaru agree to choose the fight by dice. The first fight is Hiei vs Makintaro. Hiei wips out his katana. Makintaro asks him to make a move. Hiei holds up Makintaro severed arm. Makintaro reveals his attack, the Axe-blade fist. Hiei is too quick for him and stabs his head. Meanwhile, Genkai watches Yusuke suffer through her test.

Yusuke is still in the midst of Genkai's Spirit Wave Orb absorbtion test. After a while, Genkai realizes that this is too much for Yusuke. She tries to take the orb back, but Yusuke takes it back. He wants to finish the test. Back in the ring, Shishiwakamuru rolls the dice. It lands on Kuro Momotaro and a free space for team Urameshi. Hiei volunteers to fight. Both fighters step in, and Kuro asks for Hiei's katana. Kuro licks the blade and cuts himself with it. The fight begins. Kuro pulls something called a steaming sphere out of his belt and squeezes it. Kuro inhales the fumes from the sphere and hair starts to grow from his body. This is the first beast armor, the Armor of the Ape. Hiei tries to attack with his sword, but it breaks in three pieces. Kuro gives him a few punchs and sends him into the wall. Kuro explains once his body is hit with an attack it memorizes the pain and steaming spheres are a catalyst to make his body immune to the attack.

Hiei continues his struggle against Kuro Momataro, who has just transformed to his second armor of beast, the Phoenix Armor. Kuro decides to show off by transforming into his third, and most powerful armor, the Wolf Armor. Kuro throws his last Steaming Sphere, and he turns into his hideous wolf form. Hiei draws his broken blade, and Kuro laughs, and tells him if his sword didn't work on the first armor, how could it work on the third. Hiei uses the power he stored for his Dragon of the Darkness Flame, and puts into his sword, creating the Sword of the Darkness Flame. Kuro jumps to bite him, and Hiei kills him in midair. Next, it's Ura Urashima vs. Kurama. Ura is a small boy who fights with a fishing pole. He starts swinging it in a circle, and Kurama does the same with his Rose Whip. T

With both Ura Urashima and the newly transformed Yoko Kurama trapped in the ring, the true battle begins. Yoko finally shows himself, and unleashes an attack known as the Death Tree. Yoko Kurama demands that Ura Urashima tell him the secret of the Idunn Box. Ura says he doesn't know, and that he only joined Team Uratogi because Shishiwakamaru promised him riches. Yoko knows he's lying, and threatens to kill him. Ura finally starts telling the truth. He says that he's not even Ura Urashima,and both Kuro Momotaro and Makintaro weren't who they seemed either. That they were together when Shishi and Onji showed up, and he's about to say something else when a sword flies into the ring, and hits Ura, changing into a wolf-like creature. As the smoke clears, we see that it was Shishi that threw the sword. Juri then declares Kurama the winner. Shortly after the smoke clears, Kurama turns back into his regular form.

Kuwabara starts his battle against Shishiwakamaru. It's a duel between a sword of energy and a sword of steel.shishi is obviously the more skillful of the two. They battle on and on until Shishi unleashes one of his two special items known as the Cape of No Return. Shishi throws the cape at Kuwabara and it surrounds him. He falls through a dimensional portal into the ring that was used before the semi-finals. He finds Botan, Kayko, Yukina, and his sister there; lost. He leads them to the new ring. Meanwhile, they roll the dice again to decide the fight. It comes up on a free space for Team Uratogi, and the Masked Fighter for Team Urameshi. Hiei is prepared to take her place when she magically shows up behind him and stops him. Shishi is curious about the identity, and cuts the mask. Shishi tries to get them disqualified by saying that they're using the mask to sneak in fighters. But Toguro steps in and the comittee finds nothing wrong. A new chapter in the semi-finals is set to begin.

The match between Shishiwakamaru and Genkai begins. Genkai is very weak because she has given Yusuke her Spirit Wave power through the Spirit Wave Orb. Genkai however, has a great deal more wit than Shishi, and really nails him a few times. Shishi then decides to use his second item: the Banshee Shriek. Shishi is really excited beacause he thinks by using his sword to defeat Genkai, he'll become famous. He then shows off his power of the Chorus of a Thousand Skulls on the audience, killing many. Genkai is able to dodge it. After one more chorus, Shishi uses another of his new sword's power, the Death Cage. Genkai and Shishi are surrounded by a barrier of energy. Shishi goes in for the kill with an attack in which he puts his spirit energy into his sword when Genkai catches it and fires the Spirit Reflection Blast, blasting Shishi right through the cage.

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.

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.

Yusuke Urameshi suffers from a recurring nightmare that he just can't shake. Is this a mere inconvenience? Or are there deeper meanings hidden behind the bizarre occurrences? Genkai sends Yusuke to the home of a former Spirit Detective. But what he doesn't know is that someone knows his destination... and more about his past than he ever thought possible!

As the three strangers in Kuroko's house explain the reason for their presence, Yusuke begins to sense that something is amiss. These demons have come to him to reveal one thing: that Yusuke's ancestor resides as a king of Demon World! And unless Yusuke travels to Demon World soon, the balance of power could shift and spell the end of humans reign at the top of the food chain.

Hiei and Kurama are visited by two of the kings of Demon World with a very dangerous proposition. Meanwhile, Yusuke prepares himself for his own long journey home. He finds out that the only thing more difficult than making an irreversible decision is trying to convince Kayko that everything will be all right. Won't it?

Control of Demon World is divided among three rulers: Raizen, Yomi and Mukuro. From his deathbed, Raizen has invited his descendant, Yusuke Urameshi, to return to Demon World to train under him for one climactic battle. Yusuke's first challenge is to defeat his ancestor. If he cannot defeat one of the three kings, how could he expect to stand up to the other two?!

After years of searching, Hiei finally returns to his homeland. Hiei clearly remembers the traumatic banishing he was forced to endure. But despite his many losses, one thing was never far from his mind: complete and utter revenge! But to complete his mission Hiei must first survive an encounter with yet another demon from his past.

During a duel with Shigure, Hiei has a flashback to his childhood.  The origin of his Jagan is revealed.

Just as Yusuke and Hiei were forced to confront their demons, Kurama boldly ventures through his own past. Yomi, one of the three Kings of Demon World has summoned his former partner in crime to his inner sanctum. What secrets haunt Kurama? And why has Yomi prepared for the worst?

In a brutal power play, Yomi has forced Kurama to serve as his advisor. If he doesn't, Yomi will destroy the one person Kurama loves more than anyone. But the alliance is hardly stable, for ancient seeds of hatred lie between them. Meanwhile, a group of familiar faces from the past return for one more shot against Yusuke!

It's been nearly a year since Yusuke, Hiei and Kurama arrived in Demon World, each firmly enmeshed in its tense power struggle. Now, the three former teammates are in high positions on conflicting sides, as they head towards an inevitable clash. With Raizen's time drawing to an end, Yusuke must act fast in order to keep the tenuous peace in Demon World.

Raizen's death has upset the balance of power in Demon World. Now it is up to Yusuke to prevent the threat of total upheaval. As Mukuro and Yomi prepare their next move, Yusuke arrives at a brilliant decision that just might preserve the peace. But at what cost?

Yomi and Mukuro, preventing a full-scale Demon War, have embraced Yusuke's unlikely proposal. Peace is secured for the moment. But the battle for control of Demon World must begin. Who will win the tournament, and grasp complete power?

As the tournament to decide the king of Demon World wraps up it's preliminary round, one match continues to wage on. A father and son were pitted against each other in the random drawing.
