An enigmatic life form that comes from the Astral World. His eyes are mismatched, having one translucent eye and one golden eye. Level-headed and intelligent, and a prodigious tactical duelist.
He crashed into Yuma upon first arriving to the human world, which scattered around the 99 Number cards that contain his memories, and he lost all of his memories that are not directly related to dueling. He has been gradually learning about the human world by observing Yuma's daily life and asking him questions from time to time. He remembers everything he has been learning as an observation, and he sorts them by numerical order. Having no physical presence in the human world, his existence can only be noticed by Yuma and a very small number of other specific people. He is essentially unable to leave Yuma's side, so he is floating somewhere around Yuma all the time.
