Malty S. Melromarc, first presented under the alias Myne Sophia, emerges as a cunning antagonist shaped by royal heritage and a talent for manipulation. The eldest daughter of King Aultcray and Queen Mirellia, and sister to Melty, her upbringing under her father’s unchecked favor bred entitlement and cruelty, fostering sadistic tendencies that resisted reform. Foreign education efforts backfired, as she exploited peers and mentors alike, leveraging charm and calculated seduction for personal advantage. Her striking crimson hair, emerald eyes, and regal bearing contrast sharply with her moral decay. Even after her disownment forces her into humbler attire, observers like Naofumi begrudgingly acknowledge her arresting presence, deeming her a “waste of beauty.” A master manipulator, she masks her narcissism and ruthlessness behind feigned vulnerability, deploying false tears and fabricated victimhood to orchestrate schemes. Her false accusation against Naofumi, theft of his assets, and sabotage of Melty’s succession rights reveal a pattern of treachery fueled by greed and powerlust. She evades accountability reflexively, deflecting blame even when cornered by undeniable proof. Exiled and legally rebranded with the derogatory epithet “Bitch,” she escalates her vendetta by allying with interdestructive forces like the Vanguard of the Waves, destabilizing worlds to prolong chaos. Her psychological manipulation of heroes—triggering Motoyasu’s obsessive fixation on Filo and Ren’s spiral into avarice—unlocks their cursed powers, amplifying conflict while her own strategic miscalculations and arrogance ensure recurring defeats. Her familial strife deepens her villainy: she resents Melty’s status as heir, pursuing assassination plots to seize power, and clashes with Queen Mirellia, whose condemnations culminate in punitive disownment. Though initially shielded by her father, her complicity in the queen’s demise severs his allegiance. In spin-offs such as *The Reprise of the Spear Hero*, temporal loops test her consistency; across timelines, she remains unrepentant, her core malice immutable. Her name becomes a byword for betrayal, echoing her legacy of cruelty through countless conflicts and worlds.
