The Demon King's Daughter Is Too Kind!!

Demon King Ahriman’s grand plans hit an unexpected snag: his daughter, Doux, is so affectionate and friendly that he puts his invasion of the world on hold, worried her warmhearted behavior doesn’t suit a demon at all. Doux happily makes friends, lends a hand to anyone in need, and spreads cheer even among their supposed enemies—the humans.

Rather than reprimand her, Ahriman can’t help but praise her good deeds. With the assistance of his aide Jahi, appointed as Doux’s instructor, the demon king sets out to “correct” her gentleness and teach her to be the fearsome heir he expects—though Doux’s kindness proves harder to extinguish than anyone anticipates.
