Premieres sometime in 2026. The new PV is here. Synopsis for the source manga from AniList:
“The Demon King Ariman” He reigns above all in hell. Together with powerful demons. He seeks to conquer the entire world.
However, the Demon King halted his world conquest for a certain troubling matter… His daughter, Dou, is too kind?
That’s good, I already got baited by the one with the adventurer raising an elf. Luckily the anime ended way before he married her.
