Chika is a young woman whose life is thrown into turmoil following the death of her mother. In the wake of this profound loss, she finds herself at the center of a series of unsettling supernatural incidents. As she struggles with her grief, Chika is forced to confront strange and otherworldly phenomena that seem to be connected to her mother's passing.

This supernatural suspense manga, created by Maki Fujita, follows Chika as she navigates a world where the boundary between the living and the spiritual realm becomes dangerously thin. The story blends psychological tension with ghostly encounters, placing its protagonist in situations that test her courage and sanity. The narrative unfolds in a contemporary Japanese setting, where everyday locations become backdrops for eerie and inexplicable events. Fujita has crafted a spiritual suspense story focused on a single girl's terrifying journey into the unknown, which began serialization in Akita Shoten's Monthly Princess magazine.
