Yu-Gi-Oh!: the Unknown Duelist

I'm really grateful that I went to prison with my friends at the beginning. After all, it was Yu-Gi-Oh! Without duel disks and cards at the beginning. How can I open up the wasteland? What about the system? Is it possible that the only thing I have is these two teammates who traveled with me through time together? Woohoo, no, why do you two have so many cards? It turns out it was just my start that was so bad. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
