In 2035, a research project in Japan called the "Burst" results in an accident that creates an uncontainable artificial life form known as "Matter." This entity spreads throughout Kurobe Gorge, prompting the government to close off the once-hopeful research city. Aiko Tachibana, a 15-year-old who tragically lost her family during the Burst, discovers an incredible truth from a new student, Yuya Kanzaki. A secret lies within Aiko's own body, and the solution to the mystery can be found at the "Primary Point" - the epicenter of the disaster. As destiny brings these two individuals together with the fate of humanity at stake, what secrets will they uncover?
