Yu-Gi-Oh!

Yu-Gi-Oh! is a Japanese manga created by Kazuki Takahashi. It has spawned a franchise that includes multiple anime shows, a trading card game, and numerous video games. Most of the incarnations of the franchise involve the fictional trading card game called Duel Monsters, in which each player uses cards to "duel" each other in a mock battle of fantasy monsters. The Yu-Gi-Oh! Trading Card Game is the real world counterpart to the fictional game on which it is loosely based.

While no agents from this canon are currently known in HQ, Agent Kitty Callahan (DMS, Freelance Division) comes from a badfic that crossed Yu-Gi-Oh! with The Legend of Zelda.
