Donyatsu

In the 21st century, an unexplained catastrophe has turned Tokyo's Shinjuku ward into a desolate wasteland, completely devoid of human life. The only inhabitants left are strange, hybrid creatures born from the fusion of food and animals.

Among them is Donyatsu, a curious being who is half-cat and half-doughnut. Alongside other oddities like Begaru, a feline-bagel composite, Donyatsu navigates the ruins of this abandoned world, embarking on a loosely science-fiction adventure through the empty streets of what was once a bustling metropolis.
