Otes

Otes, also known as the Hologram Man, was a designer for the Goha Corporation who grew dissatisfied with the state of Dueling and sought to return the enjoyment of it back to the children, and he chose Yuga Ohdo to be the King of Duels. Otes would test Yuga in the form of the Hologram Man, projected from a Relic that became the subject of urban legend.
