Watashi wa Ikenie no Hazu desu ga: Fuguu Shoujo wa Yasashii Kyuuketsuki ni Dekiai Sare Shiawase ni Naru

Every few decades, a human girl must be sacrificed to the vampires. When that day arrives, Lumina—a humble church servant—is chosen in place of the local lord’s daughter. Eager to repay the church that raised her, Lumina willingly arrives at the estate of the vampire Marquis Varnox, only to be greeted by a mouthwatering feast, a luxurious room, and a warm bed. And though she's been taught all her life that vampires are cruel and ruthless creatures, this one seems shockingly kind! "If there's anything you want, please tell me. You'll never have to experience hardship again." "...Wasn't I supposed to be a sacrifice?" A cozy, heart-melting romantic fantasy about a kind-hearted vampire and an unfortunate girl whose expectations couldn't be further apart! (Source: Manga UP!)
