Haruhime Sanjouno

One of the heroines of the work. A 16-year-old fox girl with green eyes, long golden hair, and a thick tail. Formerly a member of the Ishtar Familia. After the Ishtar Familia was destroyed, she converted to the Hestia Familia and, after an expedition with the faction alliance, qualified for a rank-up, advancing to Lv.2 before the "Faction War."

She met Bell in the Pleasure Quarter and developed feelings for him, seeing the hero of the story in his efforts to save her. Polite, gentle, and simple, she speaks courteously to everyone. She is from a noble family in the Far East and has known the Takemikazuchi Familia since childhood. She has been obedient to others since she was young and only knew the outside world through books, leading her to avidly read hero tales and fairy tales. At around 11 years old, she was disowned by her father after he was scammed, and after various twists and turns, she was taken in by Ishtar as a prostitute due to her interest in magic (sorcery). In the Pleasure Quarter, she couldn't do anything on her own and would faint at the sight of a naked man, being so innocent that she is actually a virgin, though she herself is unaware of it. Despite knowing she would disappear due to the Killing Stone ritual, she obeyed Ishtar, but after joining the Hestia Familia, she showed a will to stand on her own, voluntarily taking on the role of caretaker within the Familia. She also demonstrated strength by not backing down when confronting Bete to protect Wiene, with whom she had a mother-daughter or sister-like relationship.

In combat, she has no direct fighting ability and primarily serves as a rear guard. She possesses a magic that temporarily ranks up the level of a target by one, and with the enchantment magic she learned before the expedition, she can activate it on multiple targets simultaneously. In the story, this is often used as a trump card when facing strong enemies.

Due to the enemies, including the Black Dragon, being too strong, there is a possibility that they cannot be defeated within the story's setting, making her a character introduced for the convenience of the plot. However, the author has mentioned that they felt they had finally written a heroine typical of light novels.
