In many anime series that involve time travel, the impact on personal identity is often explored through themes such as self-discovery, self-acceptance, and the consequences of altering the past or future. Characters may grapple with questions about who they are, how their actions affect themselves and others, and whether changing the course of events is worth the potential ramifications. Time travel in anime can serve as a tool for characters to reflect on their choices, values, and relationships, ultimately leading to personal growth and development.
