Fern is the young mage apprentice of Frieren and accompanies her as a member of her party.
Fern is a young human teen with purple eyes and long waist-length purple hair, styled with a straight cut and blunt bangs. She usually wears her hair down with two additional chest-length strands framing her face. After her sixteenth birthday, Fern began styling her hair partially tied back with a butterfly hair ornament gifted by Frieren.
During her travels with Frieren, she is most commonly seen wearing a long, buttoned white dress with a Victorian-style top, including a frilled collar and long sleeves, along with black boots. When outdoors, she also dons a long hooded coat black coat with a white inside layer. For her eighteenth birthday, Stark gifted her an ornate mirrored lotus bracelet, which she frequently wears on her left wrist.
After the events at Graf Granat's Domain, Graf Granat gave Fern a black, long-sleeved dress that she wears with a thick, white winter coat and purple braided scarf in colder settings.
