An Unexpected Proposal - A Change in the Demon Realm
One day, 14-year-old Yusuke Urameshi suddenly finds himself dead, having died pushing a child out of the way of oncoming traffic. Since he has such a bad personality, even the Spirit World was caught by surprise that he would sacrifice himself. Yusuke soon finds out he wasn't supposed to die and has a chance for resurrection and bringing his body back to life. After being resurrected, Yusuke becomes a Spirit Detective, along with his comrades, and one adventure after another happens, whether it be an investigation or a fighting tournament.
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. Now the vigor of youth has to beat out the patience of age. Which one will come out on top? Who will finally advance to the main tournament?
As the main bouts of the Demon World tournament get underway, some of the best and most familiar fighters are removed rather quickly. While it looks like some of the fighters' motivations for entering aren't exactly what they seemed, they all have their eyes on one warrior as the prize--Yusuke.
Kurama faces down Shigure in the ring! But Kurama has to deal with the demons of his past: namely his choice to remain in the Human World. With the boiling up of tempers and anxieties comes the resurgence of Yoko Kurama! But will Kurama find a way to keep his anger from taking over?
In the next match of the tournament, Hiei steps into the ring of battle against his former ally, Mukuro. But Mukuro has already explored the horrors of Hiei's past and knows his thirst for revenge. Will this give the bizarre, shackled fighter the advantage? As a last result Hiei prepares his ultimate weapon: the Dragon of the Darkness Flame!
As the fighters make their way through the main bracket of the Demon World Tournament, Yusuke Urameshi finds himself staring down Yomi. Both powerful warriors had their own reasons for entering, but one soon learns that he may not have any reason to continue. Which will be left standing when the dust settles?
Yusuke struggles to continue his fight with Yomi and as his demon blood continues to flow through him, his demon engery also flows out.
High school student Kazuma Kuwabara is having a typical day. He is studying hard for his college entrance exams and fending off the flirtatious glances from his female admirers. But nothing could prepare him for what happens when he arrives at a mysterious meeting with Genkai. Surprise follows surprise as one by one each member of the old gang shows up! But where is Yusuke?
