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.

Based on the children's story by Hans Christian Andersen. Gerda and Kai have been neighbors and best friends since childhood. Gerda is eleven, Kai twelve. They were happy children who worked and played as they should. All that changed when the Snow Queen's mirror broke. The shards spread all through the world, each containing evil. If a shard went inside your eye, it would turn your heart to ice. A shard went into Kai's eye. After that, he grew cold to those he loved. One night, the Snow Queen came in her carriage and took Kai back to her ice castle at the farthest north point of the world. Everyone in Kai and Gerda's village didn't know where he went and believed he died from drowning in the frozen-over lake. Gerda doesn't believe this, for she dreamed of seeing Kai enter the carriage. When a drunk man admits that he also saw this, Gerda starts realizing that maybe what she saw wasn't a dream. She packs her things and goes on a journey to save Kai and bring him back home.
