Fool Night, Vol. 3 Yasuda Kasumi (2025)

In a distant future where the sun no longer shines, Toshiro Kamiya gives up his body to a sinister floral metamorphosis for a payday. The Earth is covered in thick clouds, plants are withering, and oxygen is scarce. To fight extinction, humanity has developed a technology that turns people into plants, providing a small amount of oxygen. Is the process sustainable, and is it ethical? Toshiro must consider these questions when faced with a difficult choice: save his family or save himself. Kamiya is trying to make the most of the time he has left before completing his spiriflor transformation. But when his childhood friend Hourai becomes the latest victim of a mysterious spiriflor that somehow retains the ability to move and function like a human, Kamiya finds himself drawn into the hunt for this deadly creature.
