is a young human Mage, and she accompanies Frieren as her apprentice and party member. She is an orphaned war refugee originally from the Southern Lands, later adopted by Heiter and placed under Frieren's care after his death. Fern is a orphaned war refugee originally from the Southern Lands. She was adopted by Heiter at a young age and started learning magic, Heiter was a good father figure to Fern, in his final days, he wished for Fern to be strong enough so that he could pass in peace without regret. After Heiter's death, she became Frieren's apprentice, travelling with her in her quest for grimoires.

Appearance: Fern is a young human teen with purple eyes and long, waist-length purple hair that fades to magenta near the top, styled with a straight cut and 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. After turning sixteen, Fern also grew to be taller than Frieren. As a result of her mature and calm personality, she frequently wears a stoic expression and rarely expresses strong emotions. 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 puffy white sleeves, along with black boots. When outdoors, she also dons a long black coat with a white inside layer and a hood. For her eighteenth birthday, Stark gifted her an ornate mirrored lotus bracelet, which she frequently wears on her left wrist. Fern wields a long wooden staff wrapped with purple ribbons in battle, a gift from Heiter.

Personality: Fern has a mature personality as a result of her upbringing, leading her to often act as the mother of the party. She constantly has to help Frieren perform ordinary tasks such as waking her up due to her being a deep sleeper, feeding her, and dressing her, along with cleaning up her messes. She acts similarly around Stark, such as getting mad when he stays up late, even though they are around the same age. Despite her outward motherly nature, Fern is easily upset and can act childish when others don't cater to what she wants or offend her, and in extreme cases, pouting and completely ignoring them when they attempt to reconcile, though this can be resolved through actions like treating her with food and abiding by demands she makes. She also has a habit of following around and watching others when she is suspicious or curious about them instead of confronting them directly, as seen when she stalks Frieren after suspecting her of making poor financial decisions and investigating Stark when she struggles to find a suitable birthday gift for him. Fern is additionally a very loyal apprentice and has the discipline to train incredibly hard since she was young so she can manage on her own, ultimately becoming a powerful mage acknowledged by Frieren. She rarely cracks under pressure and is able to keep a level head in combat despite receiving injuries and battling opponents that are technically more powerful. Her devotion to learning magic stems from the loss of her parents at an early age and her subsequent adoption by Heiter; after nearly giving up after her parents' death, she was stopped by the priest, who advised her to stay alive for the sake of keeping the good memories she had. As a result, she became extremely dedicated with the maturity to learn magic and prove to him that he could pass peacefully without any regrets and without worrying about her

Abilities: Mana Concealment: Like Frieren, Fern is an expert at concealing her mana, a skill she has maintained ever since she was a child. As a result, she can often sneak up on individuals, including Demons, without being detected. She was able to catch the powerful demon Lügner off guard, which surprised him greatly as the powerful mana detection of his subordinate Linie would normally expose human mages. She was also able to approach the powerful mage Wirbel without him sensing her until she was right next to him, and even Frieren herself claims to have trouble locating Fern when she is concealing her mana. Mana Detection: Fern has shown to be more skilled at detecting mana than any other human introduced so far. She was able to determine that Serie's mana was unstable, something that not even Lernen, the first ever first-class mage and an apprentice of Serie for over 50 years, was able to do. This feat was impressive enough for Serie to request Fern be her apprentice on the spot despite initially planning to fail her.
