Kibayashi Rento is a Personification of a supernatural being descended from a family of Ents (tree-oak people). One day his arm got torn off trying to save a cat from a tree. While hes looking for the arm, he crosses a girl, Kurashina Saya, who finds his lost arm. Saya is Rentos crush, and actually a fellow Personification descended from a family of Ghouls, whose main characteristic is appetite for humanoid meat. Can romance blossom between the two supernatural beings? Slight discomfort advised. Dont worry: because hes a plant, he can regenerate his lost body parts easily, including the aforementioned arm.
