[Yu-Gi-Oh!] + [Fictional World] + [Mainly Playing Cards] + [No Female Lead] + [OCG Rules] + [High-Tech Elements]

After just battling wits and courage with Marisne in MD, I woke up and found myself sitting on the street of the future duel city!

Are physical cards just old-fashioned? Did a card player's bond theory get mocked by a kid as "overdue for retirement"?

I can’t stand it! I absolutely can’t stand it!

Faced with the Future Imp's arrogant provocation, Youjie furiously pulled out his battle-damaged card box! A strangely scratched [Conquering Fighting Spirit - Dr. Crazy Love] unexpectedly formed a fatal link with the tattered wristband!

"Look carefully, boy! This is not an antique system..."

Youjie raised Dr. Crazy Love, who was shining with ominous purple light, to the sky, and his roar resounded throughout the duel arena.

"It's my damn conquering fighting spirit!"

(Note: There are also scenes with other decks, and card effects may appear due to poor play or the author's misremembering. If you find any errors in the writing, please point them out in the comments. I will definitely correct them if I see them!)
