Frieren is Not exactly immortal, but Frieren as an elf with an extremely long lifespan. The exact details of elven aging aren’t explicitly stated in the story, but it’s clear she ages much slower than humans or even dwarves. This grants her a functionally immortal existence compared to the humans she travels with. Her perception of time reflects this; decades pass like fleeting moments for her. So while she might not be invincible, she won’t die to old age soon.
Personality
Frieren is always shown as a cool and calm Character. Due to her elvish nature, her companions often struggle to understand her emotions. Having lived for over a thousand years, Frieren’s perception of time is quite different from that of humans. For this reason, she doesn’t understand how quickly time passes for humans. For example, she viewed a ten-year journey with her comrades as brief. But after Himmel’s death, things changed; she realized she should have known him better. However, after Himmel’s funeral, she decided to understand humans better.
Despite her generally calm and carefree attitude, Frieren has her emotional sensitivities. She’s embarrassed about a slight delay in her mana detection when casting spells, a mistake even apprentice mages make. She doesn’t take kindly to being called old, holding a grudge against Stark for doing so on two occasions. When upset, she can throw intense tantrums, crying for days, which can unsettle her companions. she occasionally displays hints of insecurity about her own physique, showing subtle signs of jealousy towards Fern’s bust size.
At Last
Frieren is an elf mage who has lived for over 1000 years. As an elf, they live longer than any human or dwarf; basically, their lifespan is longer than any other species. Even though she looks like a child, her age is over 1000 years. She is also an immensely powerful mage. In the anime or manga, nowhere is it mentioned that she is immortal.
