Yuyu Hakusho Episode 46

Hiei continues his struggle against Kuro Momataro, who has just transformed to his second armor of beast, the Phoenix Armor. Kuro decides to show off by transforming into his third, and most powerful armor, the Wolf Armor. Kuro throws his last Steaming Sphere, and he turns into his hideous wolf form. Hiei draws his broken blade, and Kuro laughs, and tells him if his sword didn't work on the first armor, how could it work on the third. Hiei uses the power he stored for his Dragon of the Darkness Flame, and puts into his sword, creating the Sword of the Darkness Flame. Kuro jumps to bite him, and Hiei kills him in midair. Next, it's Ura Urashima vs. Kurama. Ura is a small boy who fights with a fishing pole. He starts swinging it in a circle, and Kurama does the same with his Rose Whip. They start having a whip battle, when Ura Urashima tells Kurama a sob story about his sick grandmother, and he was only on the team because Shishiwakamaru, the team leader, promised him riches through telepathy. He asks Kurama to kill him, cause he feels it's the only way out. Kurama says he can fake his death by allowing him to hit him with the Rose Whip in a way that will knock him out. Ura "agrees." Kurama goes for the hit when Ura Urashima disappears. He is soon hit by the fishing pole and the cruel laughter announces Kurama was tricked. Ura Urashima decides to unleash a great weapon known as the Idunn Box. The magic inside the box will cause anyone but the user who breathes the smoke to go back in age and become a helpless baby. Kurama tries to hold his breath, but he breathes the smoke, and we see him go back in age. But the Idunn Box has pushed him too far. As we know, Kurama was a fox named Yoko before possessing the human baby Suiji, well it took him back to before he was born; Kurama has transformed into Yoko Kurama!
