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.
