“The future had arrived, but it was nothing like what we’d imagined.”
Chapter 1: A Changed World
The novel opens in a near-future Japan where children are born frail and elderly, while the elderly remain healthy but burdened with longevity. Yoshiro, a 100-year-old man, cares for his great-grandson Mumei, a child with the body of an old man. Society has adapted to this inversion of aging, but the psychological toll is heavy. Yoshiro reflects on the past, when aging followed a natural order, while Mumei struggles with his fragile body.
Chapter 2: The Language of Survival
Mumei attends a school where children learn in a world that no longer resembles the one their ancestors knew. Language itself has shifted—foreign words are banned, and communication is tightly controlled. Yoshiro worries about Mumei’s future, knowing that the boy’s body may not last long. Meanwhile, rumors circulate about a government program to send “emissaries” abroad, though their purpose remains unclear.
Chapter 3: The Emissary Program
Mumei is selected as one of the children to be sent overseas as part of a diplomatic initiative. Yoshiro is torn—this may be Mumei’s only chance at a meaningful life, but it also means separation. The government claims the program will help Japan forge new alliances in a world reshaped by environmental collapse. Yoshiro suspects darker motives.
Chapter 4: Departure and Doubt
As Mumei prepares to leave, Yoshiro grapples with memories of his own youth, when the world was still recognizable. He wonders if the emissaries are merely political pawns. Mumei, though physically weak, shows resilience, asking questions about the world beyond Japan’s borders. The chapter ends with Mumei boarding a plane, uncertain of his fate.
Chapter 5: A World Beyond
Mumei arrives in an unnamed foreign country, where he encounters a society vastly different from Japan’s. The people there do not suffer from the same aging affliction, and their language is fluid, unrestricted. Mumei begins to question everything he was taught, realizing that Japan’s isolation may have been a form of self-imposed exile.
Chapter 6: Revelations and Resistance
Mumei learns that the emissary program is not purely diplomatic—Japan is seeking a cure for its children by studying foreign genetics. He also discovers that his own role is more experimental than diplomatic. Meanwhile, Yoshiro, back in Japan, begins to uncover suppressed truths about the government’s role in the aging crisis.
Chapter 7: The Return
Mumei is sent back to Japan, carrying with him new knowledge that could change his homeland. Yoshiro, now aware of the government’s deception, must decide whether to expose the truth or protect Mumei from further danger. The novel ends ambiguously, with the possibility of resistance lingering in the air.
