Kojinsa Arimasu

Akira Isomori leads a quiet, unremarkable life as an ordinary office worker. He shares his daily routine with his wife, Sonoko, a dedicated novelist whose creative career adds a unique dynamic to their household. For Akira, existence is defined by the predictable rhythms of corporate work and domestic stability. However, this mundane reality is shattered when he unexpectedly faces a catastrophic health crisis that pushes him to the very brink of death. Miraculously, Akira manages to survive the harrowing ordeal, but his reprieve comes at an unimaginable cost. In the aftermath of his brush with mortality, he discovers that his physical form has undergone a radical and irreversible change. His body has been entirely transformed into that of a woman, the result of a baffling medical phenomenon officially classified as "isomerization." This sudden biological shift forces Akira to confront a deeply disorienting new reality. Stripped of the familiar identity he once knew, he must now navigate the complexities of his altered existence while maintaining his relationship with Sonoko. What was once a conventional marriage and a simple life is now fraught with profound personal challenges, leaving Akira to figure out how to move forward in a body that no longer reflects the person he used to be.
