The concept of identity and duplication in anime is often explored through themes such as parallel worlds, clones, doppelgangers, and the idea of multiple personalities within one character. By presenting characters who are duplicates of each other or who struggle with their sense of self in the face of alternate versions of themselves, anime delves into questions of individuality, self-discovery, and the nature of existence. These narratives challenge viewers to consider what defines a person's true identity and how they differentiate themselves from others who are essentially the same.
