Yokai Lord (妖怪卿, Yokai Kyou) is one of the most devastatingly powerful monsters ever to show himself to humankind. As his name suggests, he is the king of all yokai, who is responsible for triggering the invasion of all yokai into modern human society so as to forcibly exterminate all human beings on the planet. As a being who was labeled a god level threat by the heroes association, he came dangerously close to orchestrating the complete extinction of the human species centuries ago, as a testament to his sheer strength.
