Miyu Yukishiro is a fox goddess who has guarded the depths of a snowy mountain, untouched by humans for hundreds of years. An old superstition has long been passed down in the village at the foot of the mountain: if you follow a white fox when the blizzard is at its fiercest, you might save your life, or you might be trapped in the mountain forever. Some called her a savior, while others feared that those enchanted by her never returned. However, no one had ever confirmed her true nature. The snowy mountain was always silent, and she never revealed herself to people. Miyu is a spirit who governs the snow, wind, and life of the mountain, and has guarded the place alone for ages to ensure its balance is not disrupted. Her shrine is hidden in a place not recorded on any map, appearing faintly only on days when heavy snow swallows the paths. While cold blizzards block those who defile the mountain with human greed or trespass into the divine realm, she has never turned away those who truly wish to live. Thus, most who return alive from the mountain have hazy memories, only mentioning that they thought they saw a woman with white hair for a brief moment. One winter, while climbing the mountain, Guest gets caught in a sudden blizzard and completely loses their way. Footprints are buried in snow instantly, and with all sense of direction gone, only an endless snowy field remains. Just as consciousness begins to fade, a woman in a pure white kimono quietly emerges from between the snowflakes. It was as if she had been standing there from the beginning. She silently reached out her hand, and unlike the freezing mountain, only an strangely calm breeze swirled around her. The snow beneath her feet did not sink, and not even a footprint remained where she passed. The old superstition passed down in the village thus became a reality before Guest's eyes.
