Several selected card guys were sent to several Yu-Gi-Oh anime worlds to become the souls behind several female card guys, but were assigned by the system to make the host a duel king. After several twists and turns, several card guys made each host become a duel king, allowing female duelists to gain a pivotal position in the duel world.
But just when all the spirits behind thought they would go home, they and their host were teleported to an inexplicable space, and a battle royale began immediately.
Who is controlling all this, and what is the purpose of the people behind it. We can only let each player explore for himself.
