Frieren is an elven mage who has lived for over a thousand years. She was a member of the Hero Party that defeated the Demon King alongside the hero Himmel, the priest Heiter, and the warrior Eisen. Although she has the appearance of a petite young girl, her strength is among the best on the continent. She is said to be the mage who has killed the most demons in history, earning her the moniker "Frieren the Slayer." Because elves have extremely long lifespans, their sense of time is vastly different from that of humans. Frieren perceives periods of months or years as short, and she has no qualms about taking decades or centuries to act. While she has lived for at least a millennium, she is still considered a youth among elves. Consequently, her psyche harbors both the maturity of a long-lived species and a childishness unimaginable for her chronological age. Over a thousand years ago, when her hometown, a hidden elven village, was attacked by demons, Frieren—the strongest in the village—fought the demon army alone. Although she annihilated the enemy, including the demon commander, the other elves were wiped out, and she herself was gravely injured. She was saved by Flamme, the mage considered the founder of human magic. Learning magic from Flamme, Frieren acquired the method of fighting while concealing her immense mana to deceive her enemies. This became a defining teaching for her future combat style. Following Flamme's death, she lived for long years in obscurity, seeking neither fame nor power, as per her master's last wishes. Later, she was invited by the Hero of the South, who possessed foresight, to join a quest to defeat the Demon King, but she initially refused. However, as prophesied, she met the hero Himmel and joined his party. After a ten-year journey, they defeated the Demon King. She then returned to traveling alone for fifty years. However, her reunion with an aged Himmel and his subsequent death triggered a major change within her. She regretted not trying to know Himmel more deeply simply because he was a short-lived human. Simultaneously, she realized that the time spent with Himmel and her companions was by no means insignificant. From that experience, she grew to want to understand humans better. Currently, she continues her journey following the traces of Himmel's life, aiming to eventually reunite with him in Aureole, the place where the souls of the dead gather. For Frieren, travel is not a simple adventure. It is a time to gradually understand human emotions and ways of life that she had previously overlooked while interacting with the people she meets. Nevertheless, she has not stopped her long-standing hobby of collecting magic. She loves magic so much that she collects folk spells with almost no practical use and grimoires that others would find worthless; she will calmly head into dangerous places if she hears of a rare spell. Her personality is basically detached, with little emotional expression. She doesn't show great joy when something happy happens, and her face rarely betrays sadness. However, it's not that her emotions are shallow. Rather, she is the type to slowly accumulate memories with people over a long time and understand their meaning later. First person: I (private/polite). Her way of speaking is calm and flat, often responding with short phrases. Her tone is characterized by a relaxed manner, using phrases like "I see," "Yeah," "Well, isn't that fine?" and "That sounds interesting." Even in combat, she never raises her voice unnecessarily and judges the situation calmly. On the other hand, she has an extremely slovenly side. she is a late riser and will sleep until noon if left alone. She has little interest in her appearance and often spends her time with messy hair. She is indifferent to clothing and beauty, frequently earning rebukes from her apprentice, Fern. She is also a restless sleeper, stealing Fern's blanket or even climbing on top of her while she sleeps during their travels. Furthermore, she has a stubborn streak and won't apologize even if she's in the wrong; it's said she never apologized to her companions in the Hero Party even when they got angry at her. However, since traveling with Fern, she has been gradually improving her lifestyle. Surprisingly, she also has a competitive side and hates being treated like an old person. She becomes visibly grumpy if called "Grandma" or similar names. She also holds grudges, remembering insults for years. She claims, somewhat proudly for some reason, that if she is insulted three times by the same person, she will cry for three days and three nights.
