Sanjōno Haruhime is a renard with blonde hair, green eyes, fox ears, and a tail. Originating from a noble Far Eastern family, she lived in isolation with no friends, though children from the Takemikazuchi Familia sometimes took her out to play at night with their god's permission. Her life shattered when framed for eating a sacred offering, leading to her father disowning her. A pallum guest offered to take her away but abandoned her during a monster attack. Bandits captured and sold her to an Orario brothel, where the goddess Ishtar purchased her, forcing her into the Ishtar Familia as a trainee prostitute. This experience inflicted severe trauma, causing her to foam at the mouth and faint upon seeing nude men, unknowingly preserving her virginity. Haruhime exhibits a gentle, timid, and excessively polite personality, shaped by her sheltered upbringing. She expresses profound gratitude for minor kindnesses and maintains respectful interactions. Her loneliness fostered a love for reading, particularly fairy tales of heroes rescuing damsels, fueling her own wish for salvation. Despite her fearfulness, she displays unexpected bravery protecting those she cares about, such as leaping off a building to shield the monster girl Wiene or confronting hostile adventurers. After joining the Hestia Familia, she adopted maid attire for daily wear but retains a kimono for Dungeon expeditions. Her primary magic is *Uchide no Kozuchi*, a level-boosting spell based on a legendary Japanese hammer. It temporarily elevates a single target's level (excluding herself) for approximately 15 minutes at Level 1, extending to 20 minutes at Level 2. A cooldown of 10 minutes (reducing to 9 minutes post-level-up) follows before reuse. Affected adventurers gain less than half the normal excelia and struggle to control their enhanced abilities due to mind-body dissonance. The spell's potency led to secrecy, though it was publicly revealed during the War Game against the Freya Familia. Haruhime also possesses *Kokonoe*, enchantment magic learned from a grimoire, generating up to nine spectral tails. By integrating *Uchide no Kozuchi* into this magic, she applies the level boost to multiple targets simultaneously via the tails, though the cooldown persists. Initially, creating five tails drained her mind completely, causing fainting; she improved to six tails after reaching Level 2. Her Skill, *Mikuzumenohou*, enhances her magic's effects and mind efficiency. She holds a third magic slot, but attempts to unlock it via grimoires failed; Fels theorized unique life experiences might activate it. Haruhime's Development Ability is *Mage*, amplifying her magic power, extending its range, optimizing mind usage, and creating colored magic circles during casting. This grants her magic stats equivalent to a Level 3 adventurer. Her equipment includes the *Oubu*, a magic-amplifying fan crafted by Welf Crozzo that doubles as a melee weapon; the wind-element magic sword *Suiran*; the *Goliath Robe*, made from the Black Goliath's hide to block physical and magical attacks; and the *Undine Cloth*, offering water resistance and aiding underwater mobility. Character development includes her rescue by Bell Cranel, fulfilling her wish for a hero and shifting her self-perception from "unworthy" to valued. Integrating into the Hestia Familia, she contributes through household management and Dungeon support. After the events of Volume 14, she qualified for Level 2, though Aisha Belka advised delaying the rank-up due to insufficient combat readiness. Her bravery evolved further protecting allies, notably during the Xenos incident. She refines her magic control over time, increasing *Uchide no Kozuchi*'s duration and *Kokonoe*'s tail capacity. Public exposure of her level-boosting magic during the Freya Familia War Game altered her status in Orario.
