Sati chooses Yoh to become one of the Five Warriors, but first, she needs him to prove he's got what it takes—in Hell itself! He'll have to work his way back to the world of the living before he's strong enough to command the Five High Spirits…and to do that, he'll need to defeat the spirit of his ancestor, Yohken Asakura, who killed Hao 500 years ago. Meanwhile, Team Acala track down Ren, Joco, and Horohoro, intent on killing them before Yoh can make his return!
