A high school girl, Kanami Miria, reincarnated as the seventh daughter of an aristocrat. Since she had lived a miserable life, she dreamed of living peacefully in her second life. However, she reincarnated in a super-poor aristocratic family in the countryside. In order to achieve her goal to leave the house and live a peaceful life, she practiced magic and secretly went to the Royal Girls Academy. But, thanks to her omnipotent magical power, her evaluation became ridiculous. The easygoing Miria decided to ignore all invitations and aim for a relaxing life with her omnipotent magical power.
