In the apocalypse of genetic collapse, the last pure city "Viridia" regards the "Whispering Forest" outside the city as a taboo and plague.
The younger sister of Kai, a young man from the urban area, is suffering from the terminal disease "gene annihilation", and his life has entered a countdown. When cold technology pronounces a death sentence, the only hope points to the cursed forest.
In order to save his beloved, Kai embarks on a road of no return. He will coexist with the mysterious life called "Mycelium Echo", weave forbidden genetic strings with flesh and blood, and explore the truth of the world under the double pursuit of aberrant monsters and iron-blooded "purifiers".
When "purity" means decay, but "pollution" brings new life, how will he choose? Should we live as a "monster" or be destroyed together as "human beings"?
This is a story about sacrifice, growth, and redefining "life" in the wasteland.
