First, the virus changed the world. Then, it changed me.
The “Great Reformation” began silently. A biological agent, originally designed to pacify soldiers, mutated. The result? It lobotomized male aggression while unlocking dormant potential in the female brain. Overnight, the balance of power shifted. Women became the leaders, the thinkers, the masters. Men became the gentle, domestic supporters.
Amidst this global revolution, 12-year-old Miruku Sugimura faces a personal earthquake. The star of his soccer team and a “normal boy,” he collapses during a game only to discover a shocking medical truth: he isn’t a boy. He is a girl whose gender was misidentified at birth.
As society transforms around him, with fathers donning aprons and mothers taking charge, Miruku must navigate his own transition. From learning to wear a skirt to falling in love with his former rival, Daigo, in a world where boys are now the “fairer sex,” Miruku’s journey is a microcosm of a new human history.
A sweeping, satirical, and touching saga about a world turned upside down.
