Amagi Yuryu, a Synchro Dragon enthusiast, travels to a real Yu-Gi-Oh world and encounters the extremely ferocious dungeon "Devil's Night Walk."

Tiancheng Youlong, who was holding the [Junk] deck, looked at the [Red Dragon] that suddenly appeared in his deck and came up with a bold idea.

Tiancheng Youlong: "We are all living our best."

"I've tried my best, how come you're still alive?"

"No, I picked up the card. I don't want to waste time talking to you. Go talk to my red dragon."
