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.

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?

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.

After being saved in the nick of time by Puu, Yusuke revels in his new power and resumes his battle with Sensui. Although Yusuke's skill and strength have increased, he is still clumsy with his new abilities. But there is no time to practice as Sensui bears down for the final confrontation.

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?!

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?

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.

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?
