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?
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?
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 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?
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.
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!
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.
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?!
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?
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.
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!
