Sanjouno Haruhime hails from a noble Far Eastern family, living in isolation until children of the Takemikazuchi Familia secretly brought her outside, easing her loneliness. Framed for stealing an offering, she faced disownment by her father. A Pallum guest offered sanctuary but abandoned her during a monster attack. Surviving led only to capture by bandits, sale into slavery, and eventual placement in Orario's red-light district. There, the goddess Ishtar purchased her, forcing her into prostitution within the Ishtar Familia. Despite this role, Haruhime remained a virgin; an involuntary reaction caused her to faint at the sight of naked men, a fact unknown to her. Her experiences instilled deep shame and a conviction of unworthiness for rescue or redemption. Haruhime possesses long blonde hair, green eyes, and distinctive fox ears and tail, identifying her as a renart beast-human. She wore a red kimono with the Ishtar Familia but adopted a maid outfit upon joining the Hestia Familia, though she wears a kimono for dungeon expeditions. Her protective equipment includes the Goliath Robe, crafted from Black Goliath hide, and the Undine Cloth for water defense. Her weapons are Oubu, a magic-enhancing fan forged by Welf, and Suiran, a fan-shaped wind-element magic sword. Gentle, timid, and excessively polite due to her sheltered upbringing, Haruhime exhibits kindness and eagerness to help, counterbalanced by low self-esteem stemming from her past. Fairy tales, especially those of heroic rescues, offered escape during isolation and fueled a secret wish for a hero to save her from prostitution—a wish she later deemed herself unworthy of. Despite her timidity, she displays surprising bravery to protect those she cares for, leaping off buildings to shield Wiene or confronting hostile adventurers. Highly emotionally sensitive, she gradually develops resilience through her time with the Hestia Familia. Her primary ability is the unique magic Uchide no Kozuchi, temporarily boosting a single target's level by one. Initially lasting 15 minutes with a 10-minute cooldown at Level 1, it improved to 20 minutes with a 9-minute cooldown upon reaching Level 2. This magic prevents full experience gain and causes initial difficulty controlling enhanced abilities. Her second magic, Kokonoe, generates up to nine tails, each capable of carrying Uchide no Kozuchi's effect for multi-target boosts. Initially exhausting her mind after five tails, she later managed six. The skill Mikuzumenohou accelerates her mind recovery during chanting. Her Mage development ability enhances magic power, range, and efficiency, granting magic stat strength equivalent to Level 3. Despite reading numerous high-quality grimoires, she has not unlocked a third magic slot, theorized to require a unique life experience. Relationships significantly shape her development. Bell Cranel rescued her, sparking deep romantic feelings. She respects his love for Ais Wallenstein, content with the idea of being his lover or concubine due to her perceived impurity. A shared fondness for fairy tales strengthens their bond; Haruhime reads to him during vulnerable moments. She maintains a childhood friendship with Yamato Mikoto, who attempted her rescue before Bell; their reunion involved heartfelt apologies and rekindled trust. Aisha Belka, her caretaker in the Ishtar Familia, shares a sister-like bond, often offering guidance. Haruhime views Wiene as a younger sister, protecting her fiercely—shielding her from harm or confronting adversaries like Bete Loga. With Hestia, she navigates a rivalry over Bell's affections but earns Hestia's admiration for her maternal instincts. She also participates in events with the Takemikazuchi Familia, her sole link to the Far East in Orario. Haruhime's growth reflects increasing assertiveness and self-worth. After joining the Hestia Familia, she worked to overcome dependency, contributing to dungeon expeditions despite her non-combat role. She ranked up to Level 2 following the events of volume 14, though this was initially withheld due to Aisha's advice about premature advancement. Public revelation of her level-boosting magic during the Great Faction War eliminated its secrecy but solidified her value to allies. Her daily life includes maintaining the Hestia Familia's home, reflecting dedication to her new family. Her journey culminates in a commitment to protect others, embodying her declaration: "I'm not weak. I'm not a burden!"
