The year is 2025. Five years have elapsed since the Tokyo Olympic Games were canceled following fatal terrorist attacks. An international school administered by the United Nations now occupies the former Olympic venue at Tokyo Bay's edge in the bustling metropolitan area. Among its pupils are seven teens with extraordinary powers, each possessing unique abilities, called "Flowers."
Their student personas mask their true roles as agents of a UN intelligence agency. Their mission is to eliminate other youths that pose a threat to global stability, possessing similar gifts. The Flowers must carry out their assignments flawlessly; the agency holds their relatives hostage to enforce compliance. Failure would endanger not only them but also their loved ones and the lives of those they care about.
This narrative chronicles their battle against a cruel destiny, illustrating how humanity seeks hope even when prospects seem grim despite the overwhelming odds for now.
