Melphiera Marchalrayd, daughter of a count, devotes herself to exploring the gastronomic potential of monster flesh—a strange pursuit begun by her late mother. By instructing the local inhabitants of Marchalrayd to cook these exotic proteins, she aims to curb famine in the region. Yet her distinctive palate and deep familiarity with beasts have isolated her socially: few aristocrats engage for her, derisively dubbing her the "Voracious Villainess."
During a monster assault at a royal feast—where Melphiera had been dispatched to seek a husband—Aristide Rogier du Galbraith, the crown prince"s younger sibling, rushes to her defense. Renowned for his fearsome monster‑slaying prowess, Aristide earned the moniker "Blood‑Man Duke." Captivated by Melphiera"s boldness and culinary intrigue, he promptly vows to propose.
Together, Melphiera and Aristide become the most unconventional pair in high society, determined to dispel the harsh gossip and nurture their shared passion for monsters and the craft of turning them into cuisine, inspiring others to reconsider the value of these creatures.
