In Duel Academy, Jaden Yuki was waking up from unconsciousness. "Whoa. What hit me?" asked Jaden to himself. He looked around his surroundings. Duel Academy wasn't really Duel Academy. "Syrus, Hassleberry! Are you there? Alexis? Chazz? Jesse? Anybody?"
"Jaden, are you alright?" asked a voice. Yubel appeared beside him in spirit form.
"Yeah, I'm fine. Where are we?" asked Jaden.
"I really don't know, Jaden." said Yubel. Suddenly, Pharaoh the cat opened his mouth and a ball of light popped out. Professor Banner also appeared in spirit form.
"It appears that we are in Duel Academy. But this is not the Duel Academy I remember." said Banner.
"The last thing I remember was that I got a call from Pegasus that my friends were having a reunion at Duel Academy which ended up terribly and they all got kidnapped by an unknown force." said Jaden.
"Maybe we should look around for Dr. Crowler or Chancellor Sheppard and see if they know the answer to this situation." said Banner.
"Jaden, I sense that no one is inside the school. It appears to be empty." said Yubel. Suddenly, the 3 heard a scream coming from another classroom.
"Did you hear that?" asked Banner.
"Yeah. Let's go find out who it is." said Jaden.
