Acrasia Penthesllea was living dramatically in her Auntie's custody where she gets abused every day. She stopped studying due to her Auntie's decision, instead, working 24/7 in their house is all the thing she does. Unable to go outside, she became a maid without getting paid. However, the poor girl decided to escape from that hell. That led her to get run by a rushing vehicle. Acrasia thought she finally died in that accident but when she set her eyes opened, she saw a magnificent fantasy world where she could see magical things wherever she lay her eyes. Acrasia then met a royalty guy named Lace Eupheus, owner of the Eupheus manor and heir of Eupheus Royal School. She thought that she was given a second life to live peacefully in that world but she was fully wrong, little did she know that the world she set in a rather more chaotic than before. Now she has to deal with the monsters that are called Level E; A Vampires that can no longer control themselves.
