DMM Pictures describes the anime’s story:
The Demon King Ahriman, the embodiment of evil, united the demons and invaded the world with violence and power.
But for some reason, this Demon King suddenly stopped all acts of aggression!
The reason why the most powerful Demon King in the demon world stopped invading…is this!
It’s because the Demon King’s daughter, Dou, is too kind!!
Though born a demon, Dou’s kindness knows no bounds. Her kindness is so great that she can gently soothe evil demons, violent monsters, human slaves, and even her sworn enemies, angels.
With his daughter in this state, the Demon King is so worried that he can no longer invade.
Seeing the Demon King’s anguish, his aide, Jahy, decides to turn Dou into a worthy demon, and sets out to put her through various trials. However, Jahy does not yet realize that these trials will only further broaden Dou’s kindness…
And Dou’s kindness causes small ripples in this far-from-kind world…
Sakamoto launched the manga in Hakusensha‘s Manga Park app in May 2019, and it now runs on Hakusensha‘s Young Animal Web site. Hakusensha will published the manga’s seventh compiled book volume on December 25.
