In her youth, Jeanne was a powerful witch who vanquished the evil Demon King and saved the world--but over time, the people she rescued have forgotten about her and her noble deeds. Now she is a short-spoken old woman, living by herself in a secluded forest...until she summons a cat from Earth to her home. The former city kitty is now the size of a giant, and must acclimate to this new world at Jeanne's side. Through eating the food Jeanne prepares, and offering a head for pats, can this furry feline soothe the loneliness of the forgotten witch?
