The Demon King's Daughter is Too Kind!!

Ahriman, once the dreaded sovereign of all demonkind, harbors a singular ambition: the total conquest of the world. Yet his grand campaign of darkness is abruptly derailed by an unforeseen obstacle—his own daughter, Dou. Far from the ruthless conqueror her father envisioned, Dou possesses a nature entirely unsuited for chaos and warfare. Instead of spreading terror, her boundless gentleness effortlessly softens the hearts of demons, humans, and even angels alike, turning potential enemies into charmed admirers. Faced with the collapse of his fearsome legacy, Ahriman finds himself powerless against his daughter’s overwhelming benevolence. Desperate to salvage their people's tarnished reputation, his loyal aide, Jahi, steps forward with a bold plan. Jahi takes it upon herself to mold Dou into a proper, formidable demon worthy of her royal lineage. However, this ambitious endeavor quickly proves far more difficult than anticipated. As Jahi attempts to instill cruelty and discipline, she must confront a daunting question: can any amount of demonic training truly withstand the radiant power of Dou’s unwavering compassion?
