Dear Sir Hannibal

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 he's looking for the arm, he crosses a girl, Kurashina Saya, who finds his lost arm. Saya is Rento's 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. Don't worry: because he's a plant, he can regenerate his lost body parts easily, including the aforementioned arm.
