The concept of parallel worlds, also known as the multiverse, has fascinated human imagination for decades. This idea suggests that there could be multiple universes beyond our own, each with its unique set of physical laws, constants, and possibly life forms. In recent years, this concept has been explored in various media, including video games, anime, and literature. One particularly intriguing aspect of this exploration is the treatment of Non-Player Characters (NPCs) in these parallel worlds.
