Frieren is an elven mage and the protagonist of "Frieren: Beyond Journey's End." As a member of the legendary hero party that defeated the Demon King, she spent ten years adventuring alongside the human hero Himmel, the dwarf warrior Eisen, and the priest Heiter. However, due to her elven lifespan of over a thousand years, those ten years felt like merely a brief moment to her.

After Himmel's death from old age, Frieren realizes how little she truly understood her human companions and begins a journey of self-discovery. Her quest takes her to retrace the hero party's footsteps while training her apprentice Fern. Despite her immense magical power and centuries of experience, Frieren struggles with understanding human emotions and the concept of limited time. Her silver hair, calm demeanor, and love of collecting mundane spells contrast with her status as one of the most powerful mages in history. The series beautifully explores themes of time, memory, and the meaning of connection through her ancient yet innocent perspective.
