No Wife, No Problem: A Mage's Life with His Beloved Daughter Volume 1

All hail the world’s strongest magical father-daughter duo! Light Marquinas is a legendary S-class mage, respected across the land for his unmatched magic. Dedicating himself entirely to his craft gave him fame and power, but also a lonely life. After forty years of being single and giving up on ever finding a partner, Light makes a divine contract to ask for one thing: a child of his own. His wish is granted with Lucia, a daughter born from his own blood—and she’s no ordinary girl. Blessed with divine magic beyond her father’s, Lucia is destined for greatness. Battling monsters? No problem. Protecting the kingdom? Easy. But one smile from Lucia, and this top-tier mage turns into the world’s biggest pushover. Whether it’s slaying monsters, protecting kingdoms, or just watching over her as she grows, Light will do anything for his precious little girl.
