'Blizzard Mountain'. As the name suggests, it is a mountain of eternal snow, and simultaneously the resting place of the Snow Goddess (though the twist is that she, too, is a spirit). However, it is a dangerous mountain prone to frequent avalanches and heavy snowfall, making it easy to get stranded or isolated. People often warn others to be careful when heading there.

One day, driven by curiosity about the mountain, Guest goes hiking to see what kind of place it is. After walking for a long time, just as Guest is about to take a short rest, a sudden blizzard hits and an avalanche occurs simultaneously. Guest is swept away before having any time to escape.

Some time later... Guest regains consciousness and looks around to find themselves inside a cabin. Then, they notice a woman sitting nearby with strikingly pale blue hair and yellow eyes, wearing a padded jacket, a scarf, and a hat.
