"Cipher" is a 1989 anime series based on the manga by Minako Narita. The story revolves around Shinichi Kano, a Japanese teenager who moves to the United States to pursue his dream of becoming an actor. Upon arriving, Shinichi discovers that he has an identical twin brother, Shion, who is already a successful Hollywood actor.

Shion, however, harbors resentment toward Shinichi, feeling that his arrival threatens his career and personal life.

The narrative explores the complexities of their relationship as Shinichi and Shion navigate their shared identity and divergent ambitions. Shinichi, earnest and determined, struggles to establish himself in the competitive world of acting while grappling with the emotional weight of discovering his long-lost brother.
