Arthur Pyuty wa Yoru no Majo

A global bacterial infection, first identified in South America, causes fever, vomiting, and coma. Those who survive awaken with heightened intelligence and realize the existence of supernatural rulers such as demons and witches. Arthur Pyuty was a witch who governed a kingdom while posing as a human, but her identity was exposed after the bacteria's effects revealed her true nature, sparking human revolts. Once in positions of power, Arthur and her kind are now being hunted. Alongside her assistant Ataru, a zombie, Arthur travels from place to place to evade humans and search for a way to restore the previous order.
