Trama

Frost Archmage Calista once defeated the Demon Lord. To honor her mother's dying wish, she seals her powers, marries Count Silas, and raises their son Louis. When he brings home a female commander and demands both wives share him equally, Calista reclaims her frost magic. The rival gets possessed by the Hell Lord, and demons flood the city. Calista fights beside holy knight Elliot, protects her son and city, and wins a new life.
