Born Lüge Lansarz Faubrey, thirtieth legitimate heir to Faubrey's throne and descendant of an ancient Spear Hero lineage, Aultcray Melromarc XXXII lost his parents and relatives to the Hakuko, a White Tiger demi-human race. Forced to flee to Melromarc with his blind younger sister Lucia, her later disappearance and presumed murder by Hakuko agents deepened his hatred for demi-humans, especially Siltvelt, a nation that revered the Shield Hero. Rising through Melromarc's military ranks during its war against Siltvelt, he seized the Vassal Staff by defeating its previous wielder. His strategic brilliance earned him the title "Wisest King of the West" and widespread respect. He married Queen Mirellia Q Melromarc, adopting her surname and ruling as king consort under Melromarc's matriarchal system. His reign included victories like slaying Siltvelt's supreme Hakuko leader, Tyran. He fathered daughters Malty and Melty. Excessive indulgence fueled Malty's manipulative nature, while unresolved trauma over his sister's death cemented his bigotry. This prejudice drove his unjust persecution of the Shield Hero, Naofumi Iwatani, due to the Shield's association with demi-humans. He enabled Malty's false rape accusation against Naofumi, withheld resources, and sabotaged his progress – actions fueled by Malty and the Church of the Three Heroes' manipulations, alongside fear Naofumi would ally with Siltvelt. The Vassal Staff abandoned him following his moral decline, refusing to materialize despite their lingering link. Exposed by Queen Mirellia, he was stripped of his royal title, legally renamed "Trash," and reduced to menial status. His appearance deteriorated to wearing only underpants and a cloak, marking his fall. Meeting Atla and Fohl, his niece and nephew born from Lucia, challenged his prejudice against demi-humans and sparked redemption. Queen Mirellia's death at the hands of Takt and Malty catalyzed his full atonement. He reclaimed the Vassal Staff, regained his tactical genius, and allied with Naofumi to defeat Takt. He rejected reinstating his original name, accepting "Trash" as penance. He reemerged as a key strategist, commanding Melromarc's military with restored brilliance and coordinating alliances with former enemies like Siltvelt. While reconciled with Naofumi, his relationship with Melty remained strained. He endorsed Malty's execution for her role in the queen's death.
