Yu-Gi-Oh!: Conquering the Duel World with Aleister

(Academy story, with a harem and a world where six anime settings merge. Ritual, Fusion, Synchro, Xyz, Pendulum, and Link Summons are all included, and he will become King of Games. This Alai is not genderbent: she is an ordinary female magician. Consider that a small spoiler.) After transmigrating to the world of dueling, You Lai has barely had time to lie flat when Rare Hunters corner him in an alley and start a Shadow Game. “I’ll wager my life against yours.” He draws a card.

At the last moment, he pulls out a Pot of Greed and, under the gaze of everyone present, flips the card that will decide the duel alongside Aleister “A true duelist knows that everything happens for a reason.” This is the story of a guy who crosses the academy with a jealous spirit at his side, beats decks from every corner, and saves the world along the way to becoming King of Games.
