Yuyu Hakusho Episode 47

Uraurashima has confined the ring with a peripheral space made of his fishing line; he unleashes smoke that makes everyone age reverse, thereby growing younger. However, this only transforms Kurama to his original and possibly stronger form, which is the fox demon, Yoko Kurama. Uraurashima finds himself in big trouble as Kurama calls forth a Death Tree and tries to find the real motivations for Uraurashima's team's participation in the tournament. Meanwhile, Yusuke continues to struggle with the absorption of the Spirit Wave Orb. Will he survive?
