is a Japanese manga series written and illustrated by Kasumi Yasuda. It has been serialized in Shogakukan's manga magazine Big Comic Superior since November 2020. An original net animation (ONA) adaptation produced by Sunrise and Shaft is set to premiere worldwide on Netflix in November 2026.
Plot For 100 years, a thick layer of clouds have enveloped the planet and no sunlight reaches Earth's surface. As a result, plants have withered and there is a rapidly-decreasing amount of oxygen in the atmosphere. To breathe, humanity has developed a technology of transfloration, which allows humans to be transformed into plants. Initially, only terminally ill people were selected, but the promised high reward has also attracted other volunteers. They receive all the necessary funds for the two years the transformation lasts. Thus, everyone is faced with the choice of continuing to live as a human in the desolate world or beginning a new life as a plant.
The young Toshiro Kamiya is among those who see no future in his human life. He had wanted to become a musician, but his grades in school are not good enough, and he has to pay for his sick mother's medication. He works hard and tries to save up for his education, but when his mother tries to take his savings, he loses all hope. He asks his friend Yomiko Horai to turn him into a plant so he can live happily for at least two years. During this process, he unexpectedly gains the ability to understand the language of plants. Since his mother has once again taken all his money, he uses this ability to find a new job: searching for plants on behalf of their relatives and communicating with them.
