The story begins when Kanan discovers an ancient, ornate dagger in an abandoned shrine. Unbeknownst to her, the dagger is a conduit for malevolent spirits, and her interaction with it awakens a powerful and vengeful entity. This entity, known as the "Demon of the Dagger," begins to manipulate Kanan, granting her supernatural abilities but at a grave cost. As Kanan struggles to control the newfound powers, she is drawn into a series of violent and tragic events that blur the line between reality and nightmare.
