[A virgin to sacrifice to vampires!?] Hana Sumioka has lived all her life devoted to work. Whilst waiting on the train home, Hana’s body was suffering from overwork and exhaustion. When her body can’t take it anymore, she fell off the platform of the station. She can see that the train is approaching to her and before she knew it, she was transmigrated to the world of fairy tales that she once read when she was young. Hana, who was injured by herself, is saved by Flora, the main character of a picture book. However, she was caught by Flora’s older brother, Nicholas, and sacrificed her to a man-eating monster. As soon as she realised that her blood was sucked by a man (whom we assume a vampire) her body got hot.
