Kurama is unconscious, and getting beaten to death by Baken. The announcer Koto tries to give a 10-count to stop the fight, but Baken ignores her and kicks her out of the ring. Just as Baken is about to kill Kurama, the team captain, Risho, tells him to stop. As it turns out, Yusuke was about to fire his spirit gun right at Baken if he had tried to kill Kurama. Kurama then is tossed out of the ring. Baken is declared the winner. Yusuke then gets onto the ring to confront him. Baken uses a technique built from his sweat to cover the entire arena in mist, so Yusuke won't be able to see now. Baken delivers a few blows, but the barely harm Yusuke, and he then fires a spirit gun through the arena, causing the mist to vanish.

The episode starts with Jin in the air, admiring the island. He swoops down and flys by Yusuke. Yusuke turns around and takes a punch to the face. He tries to counter with a kick but misses.

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. T
