"I've heard far too much about the era of shadows for one lifetime."

Kaiba gives her a look. "As I'm sure you know, Duel Monsters itself takes some influence from that era. And I don't know if this was ever known to the public, but in the early days of the game, a certain group of cursed relics possessed duelists and wreaked havoc on my tournaments. I tend to prefer that the past stay buried."

He sighs and shakes his head.
