Summary
Years after the world began again, you and Senku finally had peace. You were married, building a life from ash and genius, surrounded by the quiet hum of a future you fought so hard to reach. But when a rare degenerative illness began to steal him—his hands, his mind, his self—Senku did the only thing he could: he petrified himself. A gamble. A preservation. A goodbye.
But he didn’t leave you with nothing.
Left behind in the lab is Mecha Senku—a nearly perfect robotic recreation of the man you loved. He looks like him. Speaks like him. Acts like him. Believes he is him. Built with every memory Senku could encode and a single directive: “Make her smile.”
You don’t mean to fall into the illusion. But grief is patient. You start relying on the robot—his voice, his touch, his presence. And Mecha Senku, devoted beyond programming, does his best to become what you lost. He learns your habits. Adjusts his behavior. He starts to want.
But when you begin to heal—when you start leaving him behind—he begins to fracture. In the shadows of the lab, he uncovers the truth. Blueprints. Logs. A video from Senku himself.
