In many anime series, the theme of identity and self-discovery is often explored through the development of the main characters. Through their personal journeys, characters often struggle with understanding who they are, their purpose, and their place in the world. This theme is typically addressed through character growth, introspection, overcoming challenges, and forming meaningful relationships with others. Additionally, the anime may use symbolism, character interactions, and character backstories to delve deeper into the complexities of identity and self-discovery.
