Sakyu Basu

Sakyu is a demon whose appearance is that of a humanoid female, a hybrid of a succubus and another demon of unknown species. Despite being over 200 years old, she closely resembles a young, attractive human woman due to physical aging signs disappearing when a demon reaches an age of maturity. When asked why they chose to attend Akademi, they always provide the same answer: "We're looking for something." This woefully short reply is far too vague to adequately satisfy the curiosity of anyone who wants to learn more about them. However, no matter how much they are begged to elaborate, they refuse to say anything more about their intentions at Akademi. In actuality, Sakyu had lived more than 200 years; she is a demon who eats dreams to continue living, more specifically, "the dreams men have when they are sleeping". Unlike her younger sister, she is based on the trope of "tsukkomi", being knowledgeable and serious. Her supernatural power strength is "considerable", but she hides her true nature to avoid attracting attention of the monster hunters.
