Akujiki Reijou to Kyouketsu Koushaku (The Gluttonous Noble Lady and the Vampire Duke) tells the story of Teresse, a noblewoman infamous for her uncontrollable appetite, who finds herself disgraced and cast aside by her family. Just as her future seems hopeless, she crosses paths with Viktor, a mysterious and aloof duke who is secretly a vampire. Intrigued by her honesty and her unusual tolerance toward his nature, Viktor proposes a contract marriage that benefits them both: she gains protection and a new life away from scorn, while he gains a companion unafraid of his vampiric side. What begins as a pragmatic arrangement slowly develops into a heartfelt romance, blending gothic fantasy, charm, and themes of acceptance and self-worth.
