One day Judai, Manjome, and Shou were standing on the dock of Duel Academy. This is strange because they graduated 2 years ago. Why were they there then? Let's listen to their conversation to figure out.
"I can't believe we have to go back to school," Judai wines.

"At least we're in college this time, so we get more control of our schedule," Shou says to his best friend.

"Yeah," Manjome says, "and all this happened because of a new type of card."
"This is all the Synchro monsters fault!" Judai yells.

"Look, it's everyone else," Shou points to a group of people walking towards them.

"I guess I can deal with this. We do get to see all our old friends again. Maybe we'll get to hang out without the constant threat to the world this time. Plus I heard that they're working on card games on motorcycles. How awesome is that!"

(A few hundred years later)

Yusei Fudo was working on his D-Wheel when his best friend, Jack Atlas, came running in.

"Hey, Yusei!" Jack yells in his Australian accent.

"What is it, Jack," Yusei asks his friend not looking up from his work.

"I was just reading an article about Yugi Moto's successor, Judai Yuki, when I found an interesting fact. Judai Yuki and his friends, along with almost every single duelist in the world, had to go back to dueling school because Synchro monsters had just come out and there they met the person who created the D-Wheel whose name is lost to history. And we also have a meeting to go to with Yugi, Judai, Yuma, and their friends."
"Thank you."
