Harukaze Doremi considers herself to be the unluckiest girl in the world. Her parents are always fighting, her little sister makes fun of her, and her crush pines after another girl. If only Doremi could just wave a magic wand, she would have a much better life—or so she used to think. After a mishap with a real witch, Doremi becomes an apprentice witch herself, and it turns out she's pretty horrible at that, too. Now she and her two friends must study to become better at magic so they can become good witches. That is, if they can focus on their magic studies! The three apprentices will need all the luck they can get if they want to pass the witch exams and become full-fledged witches. Only then will Doremi's debt to the witch Majorika be repaid. Until then, Doremi will remain a useless little witch girl!

Bullies often target someone frail and weak—someone exactly like Yuugi Mutou. His beautiful childhood friend, Anzu Mazaki, is always there to stand up for him, but he can't depend on her forever. Katsuya Jonouchi, who is almost always accompanied by his verbal sparring partner Hiroto Honda, doesn't seem like a bad person either, despite always bringing Yuugi trouble. But most of all, Yuugi wishes for a true friend who understands him and would never betray him. Yuugi treasures his Millennium Puzzle, an ancient Egyptian artifact that was brought into his grandfather's game shop. Believing that solving the puzzle will grant him his wish, he completes the puzzle, unleashing a new personality within him—the soul of the "King of Games." Dark, twisted, strong, and reliable, the new personality named Yami Yuugi is the exact opposite of Yuugi. Upon any injustice toward him, Yami Yuugi takes over Yuugi's body and forces the opponent into a "Shadow Game." The stakes are high as whoever loses shall have a taste of the darkness that resides within their own heart. [Written by MAL Rewrite]
