Fern

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 also 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 more powerful or experienced than her. Her devotion to learning magic stems from the loss of her parents at an early age and her subsequent adoption by Heiter; after nearly committing suicide 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 Heiter that he could pass peacefully without any regrets and without worrying about her.
