Malty S. Melromarc, first known as Myne Sophia, is the eldest princess of Melromarc, daughter of King Aultcray Melromarc XXXII and Queen Mirellia Q. Melromarc, and sister to Melty Q. Melromarc. She possesses striking crimson hair tied in a ponytail with loose strands and emerald-green eyes, her notably attractive appearance forming a stark contrast to her malevolent nature. Taller than some heroes but shorter than others, she initially wears fine armor and luxurious attire, later adopting simpler garments after losing her royal status. Her personality defines itself through extreme narcissism, deceit, and a profound lack of empathy. Malty crafts a charming, flirty facade to manipulate, concealing traits like sadism, hypocrisy, entitlement, and cowardice. A consummate actress, she employs false tears and victim narratives to sway others, incapable of genuine attachment and viewing everyone as tools. Her short-sightedness and overconfidence frequently unravel her schemes, making her vulnerable to manipulation targeting her ego. Offered redemption, she remains unrepentant, refusing accountability even when confronted with undeniable proof. Her privileged upbringing was dysfunctional. Spoiled by her father, she developed destructive tendencies early, including allegedly orchestrating her brother's poisoning to sabotage a Siltvelt alliance, an act that shattered King Aultcray and increased his susceptibility to her influence. Queen Mirellia, recognizing her malice, sent her abroad, accelerating her promiscuity and manipulative behaviors. Malty's instability led the Queen to name Melty heir, fueling Malty's resentment and ambition for the throne. Her actions drive key plot events. She joins Naofumi Iwatani's party only to betray him, stealing his possessions and falsely accusing him of assault, triggering his social ostracization and unlocking his Wrath curse series. She later manipulates other heroes: Motoyasu Kitamura (unlocking his Lust curse after abandonment), Ren Amaki (triggering his Greed/Gluttony curses through theft), and Itsuki Kawasumi (exacerbating his Pride curse). Exposed in a trial, Queen Mirellia disowns her, strips her royal status, renames her "Bitch" (later "Witch"), and brands her with a slave crest. Subsequently, Malty allies with destructive factions like the Church of Three Heroes and the interdimensional terrorist group Vanguard of the Waves. She betrays allies during critical moments, abandoning Motoyasu during the Spirit Tortoise conflict and stealing party resources. Her most egregious act involves conspiring with Takt to assassinate Queen Mirellia, prompting King Aultcray to endorse her execution. She dies repeatedly across timelines: fatally stabbed by Rino, killed by Motoyasu in multiple realities (via explosions and spear strikes), and relentlessly targeted in spin-offs like *The Reprise of the Spear Hero*, where Motoyasu's time-looping persona dubs her "Red Pig" and eliminates her preemptively. In combat, Malty wields fire-based magic and the Whip Vassal Weapon, though her skills remain secondary to her manipulation. Her abilities include swordsmanship and exploiting political influence, but chronic betrayals and poor adaptability often lead to defeat. Her legacy is marked by infamous aliases (Myne Sophia, Bitch, Witch, Whore) and her role in perpetuating cycles of revenge and suffering.
