Yuuka Midarezaki

As the eldest daughter of the Midarezaki family, Yuuka carries a difficult past stemming from her upbringing within the Demon's Family Himemiya, where she endured mistreatment under their "Solitary Doll" tradition, particularly from her biological sister. Despite these traumatic experiences, she maintains a remarkably calm and gentle demeanor. Her true name is Reiko Himemiya.
