A hero's son, Dariel, was kidnapped and raised by his demon lord enemy to be his subordinate. But when Dariel is thrown out, he must find his own way to his own place in the world.

After losing his job as a Dark Soldier of the Demon King's Army for his lack of magic ability, 30-ish-year-old Dariel has found himself in a village of humans to spend his early forced retirement. But this unemployed magic-less demon has found a new calling as an adventurer. His second life might just be not so bad after all, as long the villagers don't find out he's not human.—Crunchyroll
