The Dark Tournament finals have just begun and Kurama finds himself facing the strangely magnetic yet dangerous Karasu. Kurama, believing that it's his only chance to defeat his eerie opponent, transforms himself into the powerful and equally ruthless Yoko Kurama. Things seem to be looking up, but will Kurama's metamorphosis be enough to conquer Karasu?

A disappointing verdict is handed down in the Kurama versus Karasu match, reversing Team urameshi's fortunes in the Finals of the Dark Tournament. Hiei seeks to recover from this setback in the ring with Bui, but will the power lurking beneath Bui's armor be too much for him?

Yusuke's body has undergone an intense transformation as his dormant demon blood takes hold. As the battle against Sensui concludes, Koenma tells Yusuke that he must choose between Demon World and Living World. Without hesitation, Yusuke makes his decision!

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?!

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?

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 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?
