The world is always changing. Every year, new species and adaptations change the balance of their ecosystems. This visual effects-intensive short film was filmed in Shikoku, Japan. It is a film with an in-depth understanding of the world of dust. A deadly new plague with mysterious dust is destroying villages around the world's oldest city, Kabé. Irez ú mi, a tracker who lives in the abandoned suburb of Kabe, is hired by businessmen in the city's underground pharmaceutical industry to study the dust that has fallen into the city. Unwilling to find a cure for this abnormal disease, Irezumi reluctantly agreed to find the source of the disease in the countryside. Little is known about dust and the diseases it causes, but as dust continues to consume the countryside, Cabe is preparing to close the door-refusing to shelter anyone outside the wall.
As the city was gradually cordoned off, the two men embarked on a dangerous journey to the countryside to find the source.
