So this is the world of a card gamer? Yattaze!

The old man by the roadside, who usually practiced slow-paced Tai Chi in the morning, was instead standing before a dueling platform, glowing with vitality and shouting at the top of his lungs, "My turn!"

The name of his location had become "Domino City," and the most famous company in the area was called "Kaiba Corp"... This was the world of Yu-Gi-Oh! Even Lin Xun himself had inexplicably changed his name to "Hayato Kobayashi," and his hairstyle had become one that clearly signaled he was good at playing cards. While he was still in a daze, a voice reached Hayato's ears— "Beep, you King of—Your starter card pack has arrived."
