Cacao, a student at Micro Grand Academy, wakes one morning to discover a wooden girl sleeping beside him. She is Hinano, a tree spirit who has possessed the body of a wooden puppet after Cacao accidentally disrupted his magic teacher’s spell. Instantly taken with Cacao, Hinano decides to enroll at the academy. With Hinano’s presence, a host of bizarre elements enter Cacao’s life: monsters, two odd twins and their four‑eyed cat master, a demon boy, eccentric teachers and classmates, and the possibility that he could become one of the greatest magic users of all time. As a result, Cacao’s days become increasingly chaotic and peculiar.
