After spending two years in a coma caused by a traffic accident, Shiki Ryougi awakens with amnesia. One day, Shiki is visited by Touko Aozaki, a wizard and proprietor of a studio called "Garan no Dou." Due to the loss of her alternate personality, Shiki has lost not only any memory of her accident, but also any real sense that she's alive and spends her days as a mere empty shell of herself. Strange, enigmatic beings begin to attack her, trying to take control of her body, now that her soul is hollow. However, one day, she confronts the attackers who've resorted to force and Shiki makes the decision to fight of her own volition.
