Tsukasa is a first-year graduate student at Keio University, where she originally studied Humanities and Geography. She is a kind-hearted human who falls in love with Yuuki Anzai at almost first sight. Despite the difficulties of being in a devil/human relationship, she stays positive and is always trying to make it work. She is strong willed, determined and stubborn at times, as well. She cares about Anzai and his suffering as a half-devil very much and is constantly looking for something she can do to help him. After becoming more aware of the devils' situation in society and learning more about them, she is thinking about researching the devils, or rather study sociology and about devil problems, as she claims that devil problems are human problems as well.
