The Devil is a Part-Timer!

The Devil is a Part-Timer! is a comedy fantasy series that follows Sadao, the Devil King, after he is defeated by the hero Emilia and transported to modern-day Tokyo. Stripped of his powers and unable to conquer anything in the human world, Sadao must adapt to a completely ordinary life and take a job as a part-time worker just to afford rent and food. The series balances humor with genuine character development as an all-powerful demon navigates the mundane realities of employment, friendship, and unexpected romance.

The show aired in spring 2013 as a thirteen-episode television series. It combines comedy with slice-of-life elements and romance, creating a lighthearted take on the isekai concept where the setting swap becomes the source of the story's comedy rather than its central conflict. The premise works because the contrast between Sadao's fearsome nature and his current powerless situation drives the humor—he is forced to be responsible, considerate, and genuinely competent at his job despite being fundamentally out of place in the modern world.

If you enjoy stories where fantasy elements collide with everyday life, or comedies that balance absurdist humor with surprisingly heartfelt moments, this series offers a refreshing take on the genre. The complete season is finished airing, so you can watch the full story without waiting for new episodes.
