Yu Yu Hakusho - Saga of the Three Kings (1994)

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.
