Now a filthy human crime lord named Tarukane has kidnapped Yukina, planning to extract her tears through torture and make a fortune! Yusuke, Kuwabara, and Botan must quickly mount a rescue mission. But why is Hiei not allowed to know?

Kuwabara's fight with the elder Toguro brother comes to a smashing conclusion, leading into Yusuke's grudge match with the younger Toguro. But before that bout can begin, intrigue at Team Toguro culminates in a shocking proposal from Sakyo and an even more shocking response from Koenma!

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.
