Description
Asirpa is a young Ainu girl and a skilled huntress who becomes the central partner to the story's protagonist. She possesses a small, agile frame with long dark hair and distinctive blue-green eyes, an inheritance from her father. Her traditional attire consists of a white Ainu robe made from attus bark fiber, known as a cosmic, which features swirling traditional patterns, worn over a purple kimono. She completes her outfit with dark leggings, deerskin boots called yukker, a protective headband known as a matanpushi, and heirloom ninkari earrings.

Asirpa initially presents as a cold and withdrawn individual, a demeanor that masks the deep emotional wounds from her past. After the death of her father, she became withdrawn and rarely smiled, finding solace only in the company of her wolf companion, Retar. This changed when she formed a bond with Sugimoto, which helped her recover her playful, cheerful, and spirited nature. When among friends and family, she is jovial, enthusiastic about cooking and hunting, and enjoys teasing her companions, particularly Sugimoto and Shiraishi. However, she is defined by a pragmatic understanding of the natural world. As a hunter, she knows that weakness leads to death in the wilderness, making her mature, serious, and decisive during a hunt or when planning their next move. Despite this pragmatism, she holds a strict personal code, refusing to kill other human beings even when her own life is in danger. She can also be stubborn and domineering, famously using her severe glare to pressure Sugimoto into eating unusual animal parts.

Asirpa is deeply rooted in Ainu culture, which teaches that nature and animals are gods, or kamuy, to be respected. She always honors her prey and never consumes the meat of an animal that has killed a man, deeming it a wen kamuy, or evil spirit. However, she considers herself a modern Ainu woman and selectively dismisses certain traditions, such as tattooing her mouth or believing in fortune-telling. This cultural identity is the core of her motivation. While she initially joins the search for gold to avenge her father, her journey and the revelations she uncovers lead her to a larger purpose. She ultimately decides to find the gold to ensure the preservation of the Ainu people and their culture, protecting her people's independence from being erased or forgotten.

In the story, Asirpa acts as the expert survivalist and guide, possessing a deep knowledge of Hokkaido's flora, fauna, and harsh winter conditions. Her role is symbiotic with her partner, as her wilderness skills complement his combat prowess. The most significant relationship is with her partner, whom she trusts completely and refers to as her "one and only partner." He is fiercely protective of her, while she grounds him in the moral code of the wilderness and gives him a purpose beyond simple greed. She also forms a close bond with Shiraishi, the trio often operating as a cohesive unit. Her relationship with the sniper Ogata is more complex, acting as rivals and foils to one another, sharing a deep and troubled connection. Other key figures in her life include her uncle Makanakkuru, who notes how her partnership has brought back her smile, and her late father Wilk, a central mystery she seeks to understand.

Asirpa's development throughout the story is marked by her emotional healing. She begins burdened by the loss of her father and a deep-seated fear of abandonment, uncertain if her companions will stay by her side once the gold is found. Through her journey and the bonds she forges, she rediscovers her smile and sense of purpose, evolving from a girl seeking personal vengeance into a young woman determined to safeguard her people's future.

Her notable abilities are extensive and rooted in traditional Ainu knowledge. She is an expert hunter and trapper, skilled in archery with her longbow, and knowledgeable in brewing poisons and preparing traditional medicine. She is also a proficient cook of Ainu cuisine, capable of preparing meals from anything she hunts or forages. Despite little formal training, she is a talented artist, responsible for sketching the tattooed prisoners as clues. Her name, Asirpa, means new year in the Ainu language but can also translate to future, reflecting her role as a symbol of her culture's continuity.
