A legitimately incompetent onmyoji tries to do his job while his supernatural clients slowly realize he has no idea what he's doing. The comedy doesn't come from slapstick or timing gags, it comes from watching a deeply mediocre person commit completely to work he's terrible at, surrounded by spirits and demons who are somehow worse at their own existence than he is at his. Slice of life anime usually hide their ambition behind wholesome vibes. This one just lets you watch a guy fumble through a world that should terrify him, and the fact that nothing catastrophic happens is somehow the funniest part. It's built for people who find relief in competent incompetence, who see themselves in someone trying and failing in the most mundane possible way. The show doesn't need high stakes or perfect animation to land. It just needs you to care about a guy who definitely should not be doing this job, doing it anyway.
The series follows the daily life of an onmyoji who is not very competent at his work.
