This episode begins with the fight between Risho and Kuwabara underway. Risho is beating the crap out of Kuwabara, who can't even use his spirit sword. Outside Shizuru, Kayko, Botan and Yukina are trying to get back inside. The demon security guard won't let all four back in, so they show him some human butt kicking. They get chased by more security guards unless they see Toguro. Yukina has flashback to her kidnapping. Toguro, however, lets the four go by. He wants the Urameshi team to win because he wants a rematch with Yusuke, as Sakyo promised. Eventually Kuwabara get cocky and forces Risho to show his Shinobi strength. Risho is the Master of Earth. He holds up his finger and the ground shakes. Risho uses his Armor of Clay techinique to cover his body with earthen armor. He jumps up in the air and crashes into the ring like a giant meteor.

He falls through a dimensional portal into the ring that was used before the semi-finals. He finds Botan, Kayko, Yukina, and his sister there; lost. He leads them to the new ring. Meanwhile, they roll the dice again to decide the fight. It comes up on a free space for Team Uratogi, and the Masked Fighter for Team Urameshi. Hiei is prepared to take her place when she magically shows up behind him and stops him. Shishi is curious about the identity, and cuts the mask. Shishi tries to get them disqualified by saying that they're using the mask to sneak in fighters. But Toguro steps in and the comittee finds nothing wrong. A new chapter in the semi-finals is set to begin.
