In this world, where diverse beings dwell, such as elves, beastmen, and fairies, there exist those who are disliked: mixed breeds. One example is Acht, a girl with recollections of a past existence on another realm. Due to her unique heritage, she faces rejection wherever she goes, unable to secure lodging at an inn or find employment opportunities. Her life presents numerous challenges, which she endeavors to surmount through the wisdom gleaned from her previous existence. However, when she does so, it attracts unwanted attention from individuals like a research-obsessed royal magician, a malevolent prince, and even a notorious pirate captain, who dub her "Sage" and relentlessly pursue her everywhere.
