Otogi Riyuji is a 16-years-old boy with black hair and green eyes. His first appearance in the anime is right after the Duel Kingdom as a new student in Yugi's school. He becomes the most popular boy in the school after he shows a game with dice to the girls. Otogi is the creator of the game "Dungeons, Dice, Monsters". This game was supposed to be sponsored by Maximilian Pegasus but after the Duel Kingdom they lose contact and the contract is terminated. Otogi is not a person who wants only money, he wants to become famous by beating Yugi Muto. He fails to do so and ends up becoming friends with Yugi and his friends. Finally, his game is accepted. Otogi is a game store owner, too. He becomes a competitor to Solomon Muto's store.
