Yu-Gi-Oh! The Sacred Cards

The game starts when the player and his two friends, Yugi Muto and Joey Wheeler are preparing for the Battle City tournament of the card game, Duel Monsters. In order to win the tournament, the player must obtain six Locator Cards which are received after beating certain characters in Duel Monsters. After all of the locators are obtained, the player is entered into the finals.

However, a mysterious person named Marik has a gang of card thieves, known as the Ghouls, which he is using to obtain the three Egyptian God cards to bring the world to darkness. Marik's Rare Hunters eventually take over the whole city. Even the owner of the card shop works for Marik and tries to kill the player. Then, the player meets Ishizu Ishtar, who challenges them to a game of Duel Monsters, to see if he is strong enough to wield an Egyptian God card. After she is beaten, the player must beat Seto Kaiba, the person that organized the tournament, in order to obtain the first God card.
