Hamayū

Natsukihiko's legal wife, "Sakura no Kimi", is also his childhood friend. Her real name is Sumiko. She is the daughter of the former head of the Minami family, who lost in a power struggle within the clan, and became the adopted daughter of the current head, who is her uncle. She is the first princess.

She is tall for a woman, with a full chest and a stunning waistline, but she is a beauty without any coquettishness in her personality or behavior. She speaks in a masculine tone and has a refreshing temperament.

When she enters the palace, she does so as a member of the Minami family in the "Summer Palace", but she enters as a member of the "Former Minami Family".
