Hime is a princess residing in Edo Castle, the center of government in the anachronistic parallel world of the series. Her life within the castle walls is balanced by a secret nightlife. On most nights, she sneaks out of the castle to attend a local disco hall, where she has become a popular and well-known figure among the regular patrons.

In terms of personality, Hime is portrayed as having a strong will and a spirited nature. She is not simply a passive noble; her actions show a desire for personal freedom and enjoyment, as demonstrated by her regular forays into the commoner nightlife. Within the castle, she holds a unique position of influence. The character Jiji, who serves the lord of the castle, comments that Hime is the only one who can keep the often unruly ruler Yoshimune in check. This suggests she possesses a level of authority or persuasive power that others in the court do not.

A significant aspect of her motivation and role in the story is tied to the alter ego of the lord, Yoshimune. When Yoshimune secretly leaves the castle dressed as a commoner named Yoshi, he ends up saving Hime from a group of kidnappers. Following this event, Hime falls in love with Yoshi, unaware that he is actually Yoshimune. This secret identity creates a key dynamic in her relationships, as she interacts with the lord during the day while harboring feelings for his commoner persona at night. Her relationship with the ruler is complex; while she is one of the few who can control him, she is also romantically interested in his disguised self. No information is available regarding her development across the series or any notable abilities she may possess.
