Makai no Ossan is told in a different style than Mob Psycho 100 and One Punch Man. It's all anecdotes about demons living peacefully in a suburban underworld. There are some longer plotlines, but the story always returns to bite-sized arcs, which gives the series a true slice-of-life feel. It's got ONE's signature weird style, which, for all its roughness, has heart and style.
