Singularity—the technological tipping point when artificial intelligence surpasses humanity or merges with it completely. Quantum computers replace traditional ones; nanobots transform humans into new life forms.
In 2045, humanity reaches Singularity—but it's no utopia. The world remains filled with conflict: resistance movements and neo-hippies everywhere.
Ren Ariwara belongs to a resistance group called "Koropokkur Kotan." He creates an AI-powered quantum computer called "UJ Soumonka," then sends its consciousness back in time to intentionally alter history.
Officially, this project's goal is for UJ Soumonka to travel into the past and contact "a certain person," steering humanity toward a brighter future—but actually there's a selfish reason behind it all.
UJ Soumonka's consciousness arrives in 2017—in a computer at a small café in Sapporo—and meets three high-school girls attending Asahioka Second High School: Aoi Miyuki (smart and sharp), Wakana Fujiuraba (aspiring novelist), and Hotaru Azumaya (an ordinary girl). Their encounter with this mysterious technology begins changing their lives forever...
How will this quantum AI affect these girls' destinies? And who exactly among these three was UJ Soumonka trying to contact?
This is an SF coming-of-age story about high school girls whose lives change after glimpsing Singularity before its arrival—a story set between eras.
