Is this the world of card players? Yada Thief!

The old man by the roadside, who used to practice Tai Chi at a leisurely pace in the early morning, was now standing before a duel arena, looking radiant and shouting with vigor, "My turn!" The topics of conversation among students on campus had also shifted to "Who pulled a rare card" and "A new batch of booster packs arrived at the shop." The name of his location had become "Domino City," and the most famous local company was "KaibaCorp"... This was the world of Yu-Gi-Oh! Even Lin Sun himself had somehow been renamed "Hayato Kobayashi," and his hairstyle now looked exactly like someone who was an expert at playing cards. While he was still in a state of confusion, a voice drifted into Hayato's ears— "Beep beep, O King—your initial booster pack has arrived."
