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?

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!

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?

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

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!
