Frieren Beyond Journey's End: Frieren

  Frieren was a mage in Hero Himmel's party. They travelled along with Priest Heiter and Warrior Eisen in a ten-year journey to defeat the Demon King. She was the last member to be recruited to the party and, despite Heiter's initial impression of her mana being average, Himmel had a hunch she was the most powerful mage he had ever met.  Being an elf that has lived for over a thousand years, Frieren has a hard time forming meaningful relationships with humans because of the difference in their lifespans and how they perceive the passage of time. This generally manifests itself as laziness, since missing an important event is of no importance as she will have plenty of opportunities to relive it in the future, or as a nearly sociopathic inability to comprehend human's feelings. For instance, she tends to not notice how her lack of impatience or cold statements can affect humans around her. Her party members have also frequently stated that they can't comprehend her feelings or read what goes on in her head.
