With a case of social anxiety bordering on agoraphobia, combined with the trauma of losing her mother Wakaba Isshiki, Futaba is strongly discomfited by going outside. When the protagonist first meets her, she is a hikikomori who does not attend school and almost never leaves her room. She communicates with the world remotely via the Internet, and her adoptive father Sojiro Sakura enables her lifestyle out of guilt that he could not protect her from trauma. Having disconnected herself from humanity and the world beyond her apartment, Futaba is lonely, lives without passion and enthusiasm, suffers from suicidal depression, and questions the point in her living. When first encountered, Futaba is so consumed with self-loathing that she suppresses her desire to live, causing her Shadow Self to develop a much more helpful personality than average, one who only desires Futaba's happiness. When she first leaves her room after her change of heart, she tends to hide behind the protagonist so that she won't be seen in public, or wears masks which make it impossible to identify her. Her room acts as a sanctuary and a refuge from the chaos and noise of the outside world.
