Hephaistos is the goddess of blacksmiths in her fictional world. She possesses red hair, consistently wears an eye patch over her right eye, favors practical boyish attire, and stands 172 cm tall. As leader of the Hephaistos Familia, renowned throughout Orario for crafting exceptional weapons and armor, her group focuses primarily on craftsmanship, though some members engage in dungeon adventures. She originates from the same divine realm as Hestia and maintains longstanding friendships with deities such as Hermes and Takemikazuchi; however, her past romantic relationship with Aphrodite ended poorly and remains a sensitive topic. Her personality blends strict professionalism with genuine warmth. Enforcing uncompromising quality standards as a master blacksmith, she intimidates even skilled artisans like Tsubaki during evaluations. Beneath this stern exterior lies deep-seated insecurity about her concealed right eye, a vulnerability shared only with Hestia. Hephaistos exhibits protectiveness toward her Familia members and close associates, though she initially expelled Hestia for laziness before permitting her residence in an abandoned church. She recruited Welf Crozzo as a mentee for his latent talents, despite disapproving of his rejection of magic swords. Her divine craftsmanship produces near-artifact weapons, exemplified by the Hestia Knife forged for Bell Cranel. Worth 200 million valis, this blade grows stronger with its wielder and functions solely for Hestia Familia members. Hephaistos created it reluctantly after persistent begging from Hestia, imposing a massive debt and labor as repayment. Key developments include: * Allowing Welf Crozzo temporary membership in Hestia Familia after acknowledging his resolve during a crisis. * Initially opposing aid to the Xenos due to perceived risks, later permitting support after persuasion by Takemikazuchi and Miach. * Forgetting Hestia’s debt due to Freya’s city-wide enchantment, leading to confrontation and subsequent alliance against Freya after the spell broke. * Accepting Welf’s romantic confession despite her eye-related insecurities, developing reciprocal feelings, and later rewarding him with adamantite for his contributions during the faction war. Her technical prowess proved crucial during the War Game against Freya Familia, where she directed her smiths to mass-produce potent magic swords for the alliance. She maintains a balance between divine duties, personal relationships, and unspoken vulnerabilities.
