Taira, Tsukasa

平つかさ

Tsukasa is a first-year graduate student at Keio University, having originally studied Humanities and Geography there. 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 deeply about Anzai and his suffering as a half-devil, 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 studying sociology and devil problems, as she claims that devil problems are human problems as well.
