One is a supporting character in the anime Ray the Animation, closely tied to the series' storyline about human cloning. His defining background detail is revealed in the tenth episode, where he and the protagonist Ray are shown to be clones of a deceased woman named Honoka. Because of this origin, One's identity is bound up with Honoka; the story hints that he may carry an unusually intense, possibly Oedipal attachment to her, and he uses the initial H of her name as a personal signature. His relationship with Ray is rooted in their shared status as copies of the same original person, giving him a distinctive place in the plot once the truth about his past comes to light. The anime otherwise places little emphasis on fleshing out his personality, personal motivations, or any special abilities; his dramatic importance rests mainly on the revelation of his origins and the strange devotion he holds for the woman he was cloned from.
