An elven mage who was a member of the group that defeated the Demon King. Although she appears to be very young, she was born into a long-lived race of elves and has lived for over a thousand years. Because her sense of time is so dissimilar to that of humans, she has no qualms about working for months, if not years, at a time. After the death of Himmel, a member of her disbanded party, Frieren regretted not knowing him better during their ten-year adventure. As a result, she embarked on another journey to learn more about humanity. She has also traveled with a human wizard apprentice, Fern, since she took her on as an apprentice at Heiter's suggestion.
