Crossing through Duel City, Yugi discovers that the dueling philosophy of this world is incredibly primitive. Seeing his opponent still slamming down his card, "I'm going to Normal Summon a Lancelot," Yugi slams it onto the Duel Disk. "Watch this! This is the end of evolution, the miracle of steel!" "When your opponent controls a monster, you can Special Summon it!" "Come forth, Cyborgagon!" From Duel City onward, Yugi uses his Cyber ​​Dragon to show the world what a second-turn OTK (One-Turn Kill) is! What it means to clear the field and deliver the final blow! What the struggle of the Cyber ​​Dragon is! Kaiba: "There's a power even purer than my Blue-Eyes White Dragon..." Yugi Muto: "Um, Yugi-kun, shall we talk about bonds first?" Yugi: "No need! What's the point of a duel you don't want to win! Victory is everything! Attack!"
