Komachi Sorimono is a spirit dwelling within discarded objects at an otherworldly shrine. In the 18th century, she manifests within a transformed realm discovered by a storm-lost traveler. She particularly inhabits unused kimonos and other forsaken items such as umbrellas, which spiritual forces animate into sentience. Her being embodies the concept of forgotten belongings finding renewed purpose. The shrine's transition into an alternate dimension enables her encounter with the human protagonist, though the precise origin of her spirit remains undefined.
