Nobody expects a show about office worker shellfish to actually be funny. The comedy doesn't come from absurdity for its own sake, it comes from watching deeply flawed creatures fail at basic human interaction in ways that feel weirdly recognizable. You're laughing at something true about yourself, just filtered through a shellfish that refuses to get out of bed.
Asa da yo! Kaishain is a short-form comedy with a touch of fantasy, built around a cast of shellfish who hold down jobs. Each of these employed shellfish comes with its own selfish or odd personality, and the humor grows out of those quirks. With 744 brief episodes, the 2016 series serves its absurd premise in small, quick doses.
