Asirpa entered life as the child of Wilk and Riratte near Otaru in Hokkaido, losing her mother moments after birth. Her father schooled her early in hunting and survival, teaching nature’s unforgiving laws—how hunting sustains life and how death intertwines with existence. On a hunt, he revealed that bears live on through those who eat them, warning that misplaced compassion risks survival in the wild. He entrusted her with his secret Ainu name, Horkew Oskoni, a bond shared only with her and her late mother. Childhood loss carved deep wounds, especially when her wolf companion Retar vanished, driving her into solitude until later events drew her out. First appearing as a stoic, pragmatic Ainu girl, she wields vast wilderness mastery: trapping, brewing poisons, archery, and discerning edible plants and animals. Her ingenuity surfaces when she spares Sugimoto from a bear using toxic arrows and tactical cunning. Yet she staunchly refuses to kill humans, even defensively, honoring Ainu reverence for life while rejecting traditions like mouth tattooing as a modern Ainu. Behind her reserve lies playful humor with trusted allies, joy in cooking Ainu dishes, and gentle teasing of companions like Sugimoto and Shiraishi, though childhood abandonment haunts her, reawakening old fears. Her gear reflects her hunter’s life: a cherry-bark bow, poison-tipped arrows, a hunting knife, snowshoes, and her father’s crafted menokomakiri knife. She wears traditional Ainu dress—an attus robe over a purple kimono, deerskin yukker boots, a matanpushi headband, and tekunpe hand covers—often adorned with her mother’s ninkari earrings. Practical items like cooking spices, a deer whistle, and a punishment rod complete her kit. Her goals shift across her journey: joining Sugimoto initially to avenge her father’s death in an Ainu gold heist, she later redirects the quest to protect her people’s cultural freedom, a resolve cemented by revelations in Karafuto. Her partnership with Sugimoto anchors her story; she rescues him as an equal using her skills. Subtle hints of unreciprocated feelings for him emerge, but they settle into a familial bond. Over three years, she grows taller, nearing Sugimoto’s shoulder height, balancing cultural preservation with personal resilience while holding fast to her ethics.
