Noroigo no Meshitsukai

Renée's eternal existence is a lonely affair. Cursed with immortality, she has long struggled to find her place in a world that shies away from the unnatural. Her very nature, perceived as unsettling and macabre, recently cost her yet another job, leaving the ageless girl adrift and desperately searching for new employment to fill her endless days. Fate, however, leads her to the doorstep of a royal prison, where a prince languishes in isolation. Imprisoned due to a "curse of poison," his touch is a death sentence for any living being—a power that has sealed him away from society and condemned him to a life of solitude. The kingdom regards him as a monster, and his only companions are the cold stone walls of his cell. Then comes Renée's recruitment to serve as his personal attendant. When the prince declares that she alone can be his servant, it is not merely a command but a recognition of a kindred spirit. Who better to attend a man who kills with a touch than a woman whom death itself cannot claim? Bound by fate and their contradictory afflictions, this solitary pair embarks on a master-servant relationship that promises to challenge the very nature of their lonely existences.
