The show treats human extinction like a joke nobody's laughing at anymore, then gets funnier the more you sit with that idea. Watashi glides through a world that stopped needing us with the same detached politeness she uses to discuss faerie economics or the philosophy of decline, and that mismatch between her tone and what she's actually saying becomes the entire engine. The art style itself refuses to choose a mood, shifting between pastel whimsy and genuine unease, which means you're never comfortable enough to just coast through a punchline. This is comedy for people who like their philosophy tangential and their social collapse served with a smile, but the smile never quite reaches the characters' eyes.

Humanity is fading. After centuries of declining populations, the remnants of the human race now share Earth with faeries: tiny, intelligent creatures who've quietly filled the void left behind. A young woman called Watashi returns to her hometown of Kusunoki and takes up her grandfather's old post as an official arbitrator between humans and faeries. She picked the job expecting it to be easy, but the sweet-loving faeries have advanced technology and little concern for human safety, and keeping their candy-driven mishaps under control proves far harder than she imagined. The result is a comedic fantasy with a science fiction backdrop, built around one person trying to keep the peace between two very different races.
