In a diverse realm filled with elves, beastmen, and fairies, there exists a marginalized group despised by many: the mixed breeds. Among them is Acht, a girl burdened with memories from a past life in a different world. Rejected wherever she goes, unable to find shelter or work, her future appears bleak. Despite facing a slew of challenges, she draws upon her past life's wisdom to navigate her struggles. However, her life takes an unexpected turn when a curious royal mage, a malevolent prince, and a daring pirate captain recognize her as a 'Sage' and flock to her side, turning her world upside down.
